Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (肌腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because __________.
A.people did not know how to put out the fire
B.Elias Howe thought Thimonnier had stolen his invention
C.the sewing machines couldn’t work finally
D.workers who feared the loss of their jobs to a machine set fire
小題2:Why did the court force Isaac Singer to pay Elias Howe a lifetime of royalties?
A.Because the judge was against Singer for his unfriendly attitude.
B.Because Howe had already patented the lockstitch used by Singer.
C.Because Singer had borrowed money from Howe and never repaid it.
D.Because Singer and Howe had both invented the same machine.
小題3:Which of the following would be the best title for this passage?
A.A Stitch in Time Saves Nine
B.The Case between Howe and Singer
C.Patent Laws on the Sewing Machine
D.The Early History of the Sewing Machine

小題1:D

人類最早是用動物的骨頭和肌腱做針線來縫制的,很多人夢想發(fā)明機器來解放繁重的勞動。法國的Barthelemy Thimonnier發(fā)明了能用的縫紉機結(jié)果卻差一點被裁縫活活燒死。美國的Elias Howe發(fā)明并申請了專利雙線連鎖縫紉法,結(jié)果回到英國發(fā)現(xiàn)另一個美國人Isaac Singer改用腳工作,使縫紉機走進了百姓家,縫紉法還是他的。最終Howe成了百萬富翁,不是因為批量生產(chǎn)縫紉機,而是因為得到了他發(fā)明的版稅。
小題1:細節(jié)理解題。第三段大意是:Barthelemy Thimonnier 的制衣廠被一群憤怒的裁縫燒了,因為他們擔心會因為這個機器而丟了工作。 故選D。
小題2:細節(jié)理解題。 最后一段的大意:法庭強迫Isaac Singer付給Elias Howe專利稅。因為Isaac Singer沒有經(jīng)過Elias Howe同意,就使用了他已經(jīng)申請了專利的雙線連鎖縫紉法。Howe控告Singer侵權(quán)并獲勝,而Singer被要求付給Howe版稅。故選B。
小題3:主題歸納題。通讀全文判斷,全文介紹了縫紉機從無到有,從手動到腳動的過程,以及幾個發(fā)明人之間的故事。所以最佳題目應(yīng)該是縫紉機的早期歷史。故選D。

How long you live has a lot to do with your environment and lifestyle, but exceptional(特別的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因譜)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(標志基因組). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
小題1:Which of the following is TRUE according to Paragraph 2?
A.Most long-living people have special long-life-related genes.
B.Ninety percent of the participants lived to 100 years of age.
C.All the long-living people have only one signature genetic cluster.
D.Scientists know how the integration of the genes helps people live long.
小題2: Perls may most likely agree that         .
A.most people living extremely long benefit from not smoking
B.living longer just depends on certain genetic recipes
C.environmental factors play an important role in long-living
D.being mentally active has nothing to do with living an old age
小題3: Which of the following is FALSE according to the text?
A.Remaining socially engaged helps a person to live long.
B.A genetic recipe can accurately predict who may live to 100 and beyond.
C.Perls is the first to think living longer is just a matter of genes.
D.The older he gets, the more likely the genes contribute to his extended years.
小題4:Which of the following would be the best title for the text?
A.Genes May Predict Who Lives to 100B.Environment And Genes
C.Genes, the Secret of Long LivingD.Lifestyle And Genes

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino (厄爾尼諾). The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe(津巴布韋), Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication(出版物)Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
小題1:El Nino is known as ___.
A.the changing of the weather in southern Africa
B.the warming of waters in the Pacific Ocean
C.the weather which brings drought(旱災(zāi))to Africa
D.the weather phenomenon(現(xiàn)象)that brings heavy rains to Africa
小題2:Scientists study El Nino in order that ___.
A.they can provide a kind of early warning to the place that will suffer from drought
B.they can tell why Zimbabwe has little or no rain
C.they can do some research work in this field.
D.they can put all this information into their computers.
小題3:Which of the following is TRUE according to the passage?
A.Scientists come to understand how El Nino appears.
B.Three scientists from the USA work on this subject.
C.Southern Africa suffered a serious drought and many people died from hunger.

How to Study Smarter, Not Harder
Here are some of our favorite study tips that will help any student study smarter, not harder:
Recite As You Study
Reciting—saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.
Take Fuller Notes
Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.
Study the Middle
The best time to review is soon after you’ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.
Sleep On It
Study before going to bed, unless you are very tired. It’s easier to remember material you’ve just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you’ve fallen asleep.
Combine Memory and Understanding
There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding.
The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.
小題1: You can notice your mistakes by _______.
A.saying things out aloudB.taking notes
C.studying the middleD.sleeping on it
小題2:When taking notes, you should _______ to better help you with reading.
A.underline important notes
B.write notes in your own words
C.take down every detail
D.write as quickly as possible
小題3:The writer advises you to _______ as it is easier for you to remember material.
A.study after a period of activity
B.do some exercise after studying
C.study as soon as you get up
D.study before going to sleep
小題4:Which of the following is NOT helpful for your understanding?
A.Thinking about an idea in different ways.
B.Relating ideas and concepts with what you already know.
C.Reading from the beginning to the end without stop.
D.Going back to what first made you confused and start again.

Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.
小題1:What would be the best title for this passage?
A.Terraforming Mars.B.Saving the Earth
C.Travelling to Mars.D.A Newly-found Place
小題2:What does the underlined word “altering” mean in the second paragraph?
A.Warming.B.Changing.C.Planting.D.Building
小題3:According to the passage the main purpose of terraforming Mars is to ________.
A.do some scientific research work
B.find out its similarity to earth
C.a(chǎn)void the dying away of many other species
D.find on Mars living place for the increasing human beings
小題4:The main reason for causing many people to consider terraforming Mars is that _______.
A.there are some resemblances between Earth and Mars.
B.terraforming Mars is theoretically simple
C.we have had some experience with terraforming our own planet: Earth
D.the development of science and technology is very rapid
小題5:What’s the author’s attitude towards the project?
A.Optimistic.B.Negative
C.Sceptical(懷疑的)D.Objective.

Beautiful cars surrounded by even more beautiful models—it’s no secret why the 2012 Beijing Auto Show was popular.
The exhibition was held between April 23 and May 2.Although renowned companies showed off their top models,it wasn’t just their expensive sports cars that grabbed people’s attention.
Concept cars are a way for designers to test out their ideas on the public with complete freedom.They can try out cars with special features that could not be massively(批量)produced easily.
Designers don’t have to follow industry rules;they don’t even need to worry about whether their cars would be followed on the roads.
At the Beijing Auto Show,the@Ant by Chery was one concept car to draw a lot of attention.China Daily called it‘‘the very definition of a concept car”.
The vehicle is powered by electricity and is capable of driving itself.But the magic doesn’t end there.
The@Ant was inspired by actual ants.According to Car News China,with the help of automated telemetric systems,@Ants are able to“see” other@Ants and compare  destination information. If two are heading the same way for a while, the vehicles connect, with one car’s rear (后面的)wheels matching up with the front wheels of another car.Up to 10@Ants can be put together and will automatically connect to form a“train".This  will help save energy while traveling, as well reducing traffic jams.
The car sounds like a great idea.Further research will be needed to turn this concept  car into something for the market,but concepts like Cherry’s  show how carmakers are  working for cleaner and greener vehicles.It’s like what the@Ant motto says,“Exploring future human beings’lifestyles”.
小題1:The concept car is getting popular because         .
A.it looks like an ant
B.it is beautifully designed
C.it is exhibited as a top model
D.it conveys a new idea for the future

Below is a selection from a popular science book.
If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker(超級油輪). But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed(腐爛)and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink(收縮)as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not.
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system(邊緣系統(tǒng)). All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease.  
 
小題1:What is the color of blood in a vein near the surface of the skin?
A.BlueB.Light yellow
C.Red D.Dark reddish purple
小題2:Why do some old people look a little shrunken as they age?
A.Because their spine is in active use.
B.Because they are more easily affected by gravity.
C.Because they keep growing backwards.
D.Because their spine becomes more bent.
小題3:Which of the following statements about our brain is true?
A.In the long run, our brain probably works harder than our heart.
B.When our brain senses the spinning, we will feel dizzy.
C.The brains of the other mammals are as complex as those of humans.
D.Our feelings and emotions come from the most developed area in our brain.
小題4:What is the main purpose of the selection?
A.To give advice on how to stay healthy.
B.To provide information about our body.
C.To challenge new findings in medical research.
D.To report the latest discoveries in medical science.

Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.
小題1:What’s the main idea of the passage?
A.An auto revolution is on its way.
B.Google has developed a driverless car.
C.The Carbot has passed its early testing stages.
D.Science fiction has turned into reality.
小題2:The driverless car is safer than an auto with people because _______.
A.it uses radar, lasers and video cameras
B.it knows speed limits, traffic patterns and road maps
C.the computer has a better sense of direction than drivers
D.the software responds to emergencies faster than a human driver
小題3:The advantage of the Carbot is that _______.
A.it can drive all by itself
B.it can avoid any traffic accident
C.it doesn’t pollute the environment
D.it is the most fashionable car nowadays
小題4:70. The author’s attitude towards the Carbot is _______.
A.unfriendlyB.desperateC.criticalD.optimistic
