BEIJING (AP) — Sandstorms whipping across China shrouded(遮蔽) cities in an unhealthy cloud of sand Monday, with winds carrying the pollution outside the mainland as far as Hong Kong and Taiwan.
It was the latest sign of the effects of desertification: Overgrazing, deforestation, urban sprawl(無計(jì)劃地?cái)U(kuò)展) and drought have expanded deserts in the country's north and west. The shifting sands have gradually moved onto populated areas and worsened sandstorms that strike cities, particularly in the spring.
Winds blowing from the northwest have been sweeping sand across the country since Saturday, affecting Xinjiang in the far west all the way to Beijing in the country's east. The sand and dust were carried to parts of southern China and even to cities in Taiwan, 1600 miles (2600 kilometers) away from Inner Mongolia where much of the pollution originated.
The sandstorm in Taiwan, an island 100 miles (160 kilometers) away from the mainland, forced people to cover their faces to avoid breathing in the grit(砂礫) that can cause chest discomfort and respiratory problems even in healthy people. Drivers complained their cars were covered in a layer of black soot in just 10 minutes.
In Hong Kong, environmental protection officials said pollution levels were climbing as the sandstorm moved south. Twenty elderly people sought medical assistance for shortness of breath, Hong Kong's radio RTHK reported.
The latest sandstorm was expected to hit South Korea on Tuesday, said Kim Seung-bum of the Korea Meteorological Administration. The sandstorm that raked(掠過) across China over the weekend caused the worst "yellow dust" haze in South Korea since 2005, and authorities issued a rare nationwide dust advisory.
Grit from Chinese sandstorms has been found to travel as far as the western United States.
China's Central Meteorological Station urged people to close doors and windows, and cover their faces with masks or scarves when going outside. Sensitive electronic and mechanical equipment should be sealed off, the station said in a warning posted Monday on its Web site.
State television's noon newscast showed the tourist city of Hangzhou on the eastern coast, where graceful bridges and waterside pagodas were hidden in a mix of sand and other pollution. In Beijing, residents and tourists with faces covered scurried along sidewalks to minimize exposure to the pollution.
A massive sandstorm hit Beijing in 2006, when winds dumped about 300,000 tons of sand on the capital.
小題1:We can learn from the text that           .
A．the sandstorms were purposely made by China.
B．the writer thinks that China government should be responsible for the pollution.
C．the sandstorms badly affected the air in US.
D．China's Central Meteorological Station will be closed.
小題2:The passage tells us that the sandstorms mainly came from      .
A．XinjiangB．HangzhouC．BeijingD．Inner Mongolia
小題3:The underlined word, “respiratory” (in Para.4) means         .

Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide(一氧化碳), 45% of the nitrogen oxides(氮氧化合物), and 34% of the hydrocarbon (碳?xì)浠衔? pollution in the United States can be traced directly to automobile exhausts (廢氣). In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water.
In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents (成分) of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides.
California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent.
小題1:The author uses figures in Paragraph 1 ________.
A．to reflect the rapid growth of automobile use
B．to highlight the importance of environment protection
C．to show the consequence of automobile exhausts
D．to criticize the low quality of cars
小題2:How are nitrogen oxides formed according to the text?
A．Nitrogen and oxygen are put together in great heat.
B．Carbon monoxide and oxygen are mixed together.
C．Hydrocarbons pass through the engine.
D．Nitrogen is burned incompletely.
小題3:Which of the following is NOT true according to the text?
A．Carbon monoxide can be controlled in the engine.
B．Smog will form when hydrocarbons meet nitrogen oxides in the sunlight.
C．Hydrocarbons have no poisonous character themselves.
D．The conditions that decease emission of hydrocarbons will increase emission of nitrogen oxides.
小題4:According to the text, alcohol is added to gas in order to ______.
A．increase awareness of environment protection
B．control air pollution
C．increase the fuel efficiency
D．replace gas gradually

Teaching a child to read at a young age gives him a valuable start in life. Reading is the basic part of education and a child’s reading ability will influence his school success greatly. Learning difficulties, many of which begin from poor reading skills, can damage a school child’s confidence and affect his future achievement. Young children are programmed to learn and they can learn better with encouragement. Ten to twenty minutes of reading a day still leaves plenty of time for play.
Many parents are concerned that learning to read is too challenging a task for a pre-school child, but they should also remember that most children learn to speak by the time they are 3. Learning a language is probably the single most challenging task any individual can undertake, yet children do it without formal instruction, achieving the fluency much better than adult language students.
There is a window of opportunity in terms of IQ development, which is most open during a child’s early years. A scientific study, carried out by Dr. Peter Huttenlocher at the University of Chicago, showed that the number of connectors, called synapses（神經(jīng)元突觸）, between the nerve endings in a newborn baby’s brain is similar to the number in the average adult brain. These synapses increase rapidly during early childhood. By 12-24 months a child’s brain has about 50% more synapses than the average adult brain. After that the synapses which are not in use begin to atrophy（衰退）. For most people, from age 16, the number remains steady. It begins to drop again as we move into our golden years. Doing intellectual activities at a young age, such as learning to read, can stimulate（刺激）and preserve these connectors in the brain resulting in a long-term beneficial（有益的）effect on IQ development.
Another notable study is probably the Milwaukee project. This study took a group of babies, all of whose mothers had low IQs, and gave them special training for seven hours a day, five days a week, until they started first grade. By the age of 6 these children had an average IQ 30 points higher than their contemporaries. The overwhelming conclusion is that the early intellectual stimulation can have a positive, long-term effect on a child’s brain development.
From birth you should talk to and explain things to your baby. Reading to him can be a wonderful way of spending quality time with your child. The enjoyment of books and being familiar with the idea of print will pave the way for（為……鋪平道路）learning to read later.
If your child is a fast learner you can help him realize his potential by introducing him to the joy of the printed word at an early age. This will lay the foundations（基礎(chǔ)）for both a high achieving school career and a lifelong love of reading. If your child shows early signs of reading difficulties, your efforts may help him get rid of such problems before he goes to school.
It can be difficult to teach your own child because emotional（引起情緒激動(dòng)的）issues arise easily. Online programs for learning to read English are excellent options. They allow children to repeat new materials as many times as they need to, without wearing out the parents’ patience.
小題1:What does the passage mainly discuss?
A．Children should be taught to read at an early age.
B．Children can read better than most adult students.
C．Children have more synapses than most adults.
D．Children are supposed to learn to read on the Internet.
小題2:Why does the author mention the study by Dr. Peter Hutten locher?
A．To remove parents’ worry.
B．To explain IQ development.
C．To explain how a baby’s brain works.
D．To show the parents’ wrong ideas.
小題3:How can children benefit from learning to read at a young age?
A．It can build up great confidence in their mind.
B．It can help preserve the connectors in their brains.
C．It can help produce more connectors in their brains.
D．It can help them find both their weaknesses and strengths.
小題4:At the end of this passage the author advises _______.
A．parents not to get angry too often
B．children to enjoy reading as early as possible
C．children not to wear out their parents’ patience
D．parents to get their children to take an online program

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing?Paper,No notebooks,no test paper.Nor are there any pencils or pens,which always seem to run out of ink at the critical moment.
A“paperless classroom”is what more and more schools are trying to achieve.Students don't do any handwriting in this class. Instead, they use palm (手掌) size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student's personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they're studying from math to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan (阿富汗) over one year ago.
"We could touch every side of the country through different sites? from the forest to refugee camps (難民營(yíng))," she said. "Using a book that's three or four years old is impossible."
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
"Think about the money and trees we could save with the computers," she said.
But, with all this technology, there's always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
小題1:What does the part of the last sentence in the first paragraph, “run out of ink at the critical moment”, mean?
A．Pens may not write well at the critical moment.
B．Pens get lost easily, so you may not find them at the critical moment.
C．Pens may have little or no ink at the critical moment.
D．Pens use ink, while pencils don't.
小題2:In a paperless classroom, what is a must?
A．Pens.B．Computers.C．Information.D．Texts.
小題3:The high school teacher, Judy Herrell, used the example of her class to show that _______.
A．the Web could take them everywhere
B．the Web taught them a lot
C．the Web is a good tool for information
D．the Web better than the textbooks, can give the latest and comprehensive (全面的) information
小題4:The paperless classrooms will benefit _____ the most.
A．studentsB．teachersC．treesD．computers
小題5:What does the phrase in the last paragraph, “break down”, mean?
A．Break into pieces.B．Stop working
C．Fall down.D．Lose control.

If the eyes are the romantic’s window into the soul, then the teeth are an anthropologist’s ( 人類學(xué)家 ) door to the stomach.
In a study published last month in the journal Science, Peter Ungar of the University of Arkansas and his partner, Matt Sponheimer of the University of Colorado, US, examined the teeth of our early human ancestors to find out what they were really eating.
They already knew that different foods cause different marks on teeth. Some cause scratches, while others cause pits (坑).The carbon left on teeth by different foods is also different. Tropical grasses, for example, leave one kind of carbon, but trees leave another kind because they photosynthesized ( 光合作用 ) differently.
Traditionally, scientists had looked at the size and shape of teeth and skulls ( 頭骨 ) to figure out what early humans ate. Big flat teeth were taken to be signs that they ate nuts and seeds, while hard and sharp teeth seemed good for cutting meat and leaves. But this was proven wrong.
The best example was the Paranthropus (傍人), one of our close cousins, some of which lived in eastern Africa. Scientists used to believe Paranthropus ate nuts and seeds because they had big crests(突起)on their skulls, suggesting they had large chewing muscles and big teeth. If this had been true, their teeth should have been covered with pits like the surface of the moon. They would also have had a particular type of carbon on their teeth that typically comes from tree products, such as nuts and seeds.
However, when the two scientists studied the Paranthroupus, it turned out to have none of these characteristics. The teeth had a different kind of carbon, and were covered with scratches, not pits. This suggests they probably ate grass, not nuts and fruit stones. It was the exact opposite of what people had expected to find.
Carbon “foodprints” give us a completely new and different insight into what different species ate and the different environments they lived in. If a certain species had the kind of carbon on its teeth that came from grasses, it probably lived in a tropical grassland, for example.
小題1:The underlined sentence in Paragraph 1 probably means that _____.
A．a(chǎn)nthropologists can study the structure of human stomachs by studying their teeth.
B．a(chǎn)nthropologists can study the diet of early humans by studying their teeth
C．a(chǎn)nthropologists can learn whether humans were healthy by looking at their teeth
D．a(chǎn)nthropologists can get the most useful information about humans from their teeth
小題2:According to Paragraph 3 to 5, which of the following statements is TRUE?
A．Scratches on teeth are caused by eating nuts or seeds.
B．Pits on teeth are caused by eating grass or leaves.
C．Early humans with hard and sharp teeth ate meat and leaves.
D．Different foods leave different marks and carbon on teeth.
小題3:The example of the Paranthropus was mentioned in the article in order to _____.
A．tell readers that they are one of our close cousins living in eastern Africa
B．tell readers they had different eating habits from modern humans
C．prove that size and shape of skulls does not show accurately what early humans ate
D．tell readers that living environment makes a difference to skull structure

Lettuce (萵苣)has been eaten for over 4,500 years, and was known to the Egyptians, Greeks and Romans. Now, people in some countries start the meal with lettuce as part of a salad. There are hundreds of kinds of lettuce. The main ones include head lettuce, such as iceberg, leaf lettuce ,Boston, bibb and romaine.
Experts say lettuce is one of the easiest crops to grow in your garden. The best time to plant the seeds is during cool weather. The University of Illinois Extension advises that the best planting temperature is 15 0C.
Lettuce seeds are small, so do not place them too deep in the ground. If you plant some seeds every week or two, you will have crops ready to eat one after another.
To start the seeds inside, you can use a seed tray in your home or other shelter. This container should be deep enough to hold at least three centimeters of soil or more. There should be about one centimeter of space between the soil and the top of the container. The container should have holes in the bottom so the extra water can flow out. Drop the seeds over the surface and cover them lightly with soil. If the soil is not already a little wet, give it some water. But do not drown the seeds.
Next, cover the seed tray with paper. When the seedlings have come up far enough to touch the paper, take it off. You can transplant the seedlings into the garden when they are about two to three centimeters tall. Do this when the weather is not too hot and not too cold. Take out as much soil as you can with the seedlings, Then dig a hole in the ground bigger thanthe lettuce roots. Water the plants but not too heavily.
Harvest leaf lettuces when the leaves are big enough to eat. Pull the leaves from the outside of the planting so the inside leaves will keep growing. Or, you can cut off the whole plant. Leave about two or three centimeters above the ground so the plant will re-grow. Cut off head lettuces at ground level.
Lettuce is best when served fresh, so make a salad and enjoy. Experts say lettuce is one of the easiest crops to grow in your garden.
小題1:Which of the following shows the right order of planting lettuces?
a.Dig a hole in the ground bigger than the lettuce roots.
b.Drop the seeds over the surface.
c.Water the plants.
d.Cover the seed with soil.
e.Take off the paper.
f.Transplant the seedlings into the garden.
A．b, d, e ，f, a, cB．a(chǎn), b ，c, d ，e, f
C．d, e，f, b，a，cD．b，c, d，e，f，a
小題2:The underlined word “seedlings” in paragraph 5 means______.
A．containersB．seedsC．young plantsD．layers
小題3:When eating Iettuce5 you’d better ______ so that it tastes best.
A．store it in plastic bagsB．eat the inside leaves
C．wrap it in paperD．eat while it is fresh
小題4:What can we infer from the passage?
A．Lettuce is the easiest crop to grow in your garden.
B．The lettuce is not hard to plant and store.
C．We can plant lettuce in a two-centimeter-high tray.
D．We should water lettuce at least twice a day.

Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other．In fact, eye contact is avoided at all times. That’s not rudeness ― people are just too busy to bother looking．
　　Busy doing what, you ask? Well, they’re certainly not using the time for a moment of quiet thinking．Nor are they reading a book．New technology has replaced quiet habits．Today the only acceptable form of book on the London underground is an e-book．
　　Apple must earn a fortune from London commuters（使用月票上下班者）. Since the launch of the iPhone in 2007, over 40, 000 ― yes, 40, 000 “apps” have been designed．
　　Commuters love them because they are the perfect time - fillers. One “app”, called iShoot, is a game that features tanks．Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination. iSteam clouds the iPhone screen when you breathe into the microphone. You can then write in the “steam” on your phone screen．
　　For those without an iPhone, another Apple product, the iPod, may be the distraction (消遣) of choice. It’s not just teenagers who “plug in” to their music － iPods are a popular way to pass the time for all ages．
　　And if games, e-books and music aren’t enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work．With all these distractions, it’s amazing that people still remember to get off the train．
小題1:Those who want to save time to reach where they go can download ________ to their iPhones
A．iShootB．Tube ExitsC．iSteamD．iPod

小題3:The underlined word “apps” in the third paragraph means ________．
A．computers
B．programs downloaded for the iPhone
C．computer companies
D．fortune from London commuters
小題4:The main idea of the passage is that ________．
A．London commuters are unfriendly to strangers
