Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency  identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes(密碼) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake(假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip,you would need an operation to remove it.
小題1:The Verichip is         .
A．the identity number B．the security code
C．a(chǎn) tiny microchipD．a(chǎn) radio reader
小題2:Paragraph 3 is mainly about         .
A．how the Verichip works
B．the importance of the Verichip
C．the development of the Verichip
D．how money is taken from your accounts
小題3:Which is true of the Verichip?
A．Your information on it will always be safe.
B．Medical records have already been included.
C．You can easily reach for your wallet using it.
D．An operation has to be performed to remove it.
小題4:What can be inferred from the text?
A．All people are satisfied with the chip.
B．The Verichip company has financial problems.
C．The chip needs improving to be widely accepted.
D．Many people have the experience of losing keys or money.
小題5:The author's purpose of writing the text is most likely to         .

A practical English Grammar is intended for intermediate（中級的） and post-intermediate students. We hope that more advanced learners and teachers will also find it useful.
The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on controversial forms.
In the fourth edition the main changes are as follows.
1. Explanation and examples have been brought up to date.
2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of place, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns.
3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice.
4. The contents list now summaries every edition heading, and there is a new index containing many more entries references.
In this edition the sign “~” is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign “="”" sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech.
We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項多余選項。
It’s not news that we spend more time than ever texting and online.1 Yes, that’s right: a 2010 study shows that more teens are reading good old-fashioned, ink-on-paper books.
Reading is a good way to discover the next big thing and to learn a little more about yourself while you’re at it.2 Here are some tips.
Start with your interests
Reading on your own isn’t like reading for school. You can pick something that’s all about your interests, whether it’s ancient martial arts, computers, or fashion design.
Reading the blurbs(簡介)
The reviews and quotes on the back and inside covers of many books are called “blurbs”. 3if you find a book you really like, take a minute to read the quotes(if there are any) and see which authors praised the book. Often, they’ll have similar styles and you might find you like books by those authors too.
Ask an expert
4 Explain your interests--- rock stars, sports teams, historical events, humors, whatever you’re into—and any writers you like, and your librarian can point you toward books that you’ll love.
Finally, you’ll probably enjoy what you’re reading a lot more if you find a quiet place and make time for the book.5 You can put on some good music(ideally without lyrics), get yourself some tea and a comfy spot, and let yourself be carried away by the book.
You’ll see that time does fly when you are reading something you love!
A．Join a group with your friends and people you trust.
B．But do you know how to pick a book you’ll really like?
C．But did you know that we also spend more time reading?
D．Your local library can hook you up with a whole lot of great book ideas.
E. What was your mother’s favorite book when she was your age or your dad’s?
F. We all multitask, but most reading is best enjoyed when you can concentrate and focus on it.
G. They give you an idea of what the book is about, and can also help you pick future books too.

As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the
animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、職業(yè)) in science.
Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty?”
Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.　
小題1:According to the passage, which of the following statements is true?
A．People are curious in the same way.
B．People in different countries are interested in different things.
C．Men and women are curious about different things.
D．People of different ages are interested in different things
小題2:Scientists who work with the biological sciences study____.
A．the earth , the oceans and the sky
B．man-made things
C．plants and animals
D．ocean water
小題3:When you run, your muscles need ____.
A．more nutrition and oxygenB．more signalsC．more saltD．water

Some of Man's closest relatives in the animal kingdom are under serious threat because of human activity, according to a recently published report.
Almost one in three of all apes and monkeys are now considered to be in danger of dying out and disappearing from our planet, if action is not taken soon.
The report, which was produced for the World Conservation Union (WCU), shows that 114 of the world's 394 kinds could be lost forever, and the main reason they are threatened is the continuing loss of forests where most of these animals live. In addition, illegal wildlife trade, climate change and commercial（商業(yè)的）hunting for meat are also endangering them.
What's more, the problem is getting worse. The number of species on the organization’s Red List has increased by 3 to 25 since 2005.
Russell Mittermeier, the main researcher of the WCU report, said, "You could fit(安置) all the surviving members of these 25 species in a single football stadium. So the problem is obviously urgent."
The scientists, who drew up the Red List, believe that the situation is now so bad that if action is not taken immediately, it will result in primate(靈長目動物) species dying out - something which has not happened in over a century.
The loss of habitat caused by the clearing of forests for wood, farmland and fuel continues to be the main reason for the decreasing number of primates, according to the report, and the problem was most severe in Asia.
The loss of forest trees is also responsible for 20 percent of all greenhouse gases - more than all the cars, trucks, trains and airplanes in the world combined.
小題1:What is the main subject of the report discussed in the text?
A．Climate change.B．Loss of animal habitat.
C．Animal protection.D．Endangered animals
小題2:How many animals were on the Red List in 2005?
A．22 B．19C．25. D．28.
小題3:The spokesman refers to 'a football stadium' in paragraph 5 to stress that ______.
A．the animals enjoy playing sports
B．these animals should be placed there for protection
C．there are not many of these animals left
D．the report was announced there
小題4:What is the main cause of the greenhouse gas problem according to the text?
A．Airplanes.B．Loss of trees.
C．Factory pollution.D．Road vehicles.

Apple has entered the textbook market. The tech giant（科技巨頭） introduced iBooks textbooks a couple of weeks ago when it announced its iBooks 2 platform. They are digital books in many subjects taking in science, maths, history and geography.
Apple developed its iPad-based textbooks in conjunction with（連接）major textbook publishers. The company offers a collection of textbooks for high school students.
Apple says it offers a “new textbook experience” and suggests its iBooks textbooks are “the next chapter in learning”. It sounds like good news for pupils and students. Think of it. No more carrying heavy backpacks full of textbooks. Every textbook you require can be stored on your iPad. No more having to buy expensive textbooks which you will only use for a year or two and then sell or give away.
Of course there’s a catch. You need to own an iPad and as you know, it is not cheap. You also need to buy digital textbooks, mostly priced each at $14.99 (94.74 yuan) or less. Textbook publishing was worth $ 8.7 billion in the US alone last year. And the rest, as they say, is history. Will Apple revolutionize learning? Will digital books take over completely in education? That remains to be seen.
小題1:What is the best title of the text?
A．Apple Enters New MarketB．A Different Way of LearningC．Experience Digital TexbooksD．Say Good-bye to Tradition
小題2:iBooks textbooks will do good to pupils and students because ________.
A．they are free to getB．they are easy to carry
C．they are ipad-basedD．they are favorite gifts
小題3:The underlined words “a catch” in Paragraph 4 are closest in meaning to “________.”
A．a(chǎn)n advantageB．a(chǎn) surprise
C．a(chǎn) problemD．a(chǎn)n order
小題4:What can we know from that last paragraph?
A．iPad-based textbooks have changed our learning.
B．Traditional textbooks will be replaced sooner or later.
C．Apple has earned a lot from the textbook market.
D．Digital books have disadvantages and advantages.

We all know the dangers of fires. It’s good and necessary for a family to learn how to prepare for a fire. Here are some suggestions.
Put a smoke alarm(火警) in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.
Make escape plans. We should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.
Buy fire extinguishers(滅火器) in the house. Everyone in the family should know how to use them.
Practise for a fire. We do fire practice because we teach children about fire safety. Everyone in the family should know the following fire rules:
★Don’t open a hot door! The fire can grow more quickly if you open the door.
★Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.
★What will you do if your hair or clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out. Put a blanket(毯子) around you to keep air away from the fire that may still be on you.
There are many possible causes for fires. A wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.
