When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses．This phenomenon is referred to as the bystander effect．
The bystander effect is also called the Genovese effect, which was named after Catherine Kitty Genovese, a．young woman who was murdered on March 13, 1964．Early in the morning, 28-year-old Genovese was returning home from work．As she approached her apartment entrance, she was attacked and stabbed（刺）by a man later identified as Winston Moseley．Despite Genovese]s repeated cries for help , none of the dozen or so people in the nea
rby apartment building who heard her cries called the police for help ．The attach first began at 3:20 , but it was not until 3:50 that someone first contacted the police．
There are two major factors that contribute to the bystander effect．First, the presence of other people creates a diffusion（分散）of responsibility．Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present．
The second reason is the need to behave in correct and socially acceptable ways．When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate．Other researchers have found that onlookers are less likely to take action if the situation, is ambiguous^ R^E^?）．In the case of Kitty Genovese, many of the 38 witnessing reported that they believed that they were witnessing a " lovers' quarrel" , and did not realize that the young woman was actually being murdered．The passage seems to suggest that Genovese might not have been murdered if there had been_____．
| A．no observer | B．fewer observers |
| C．more observers ． | D．younger observers |
Genovese was murdered .
| A．while she was going out | B．in her apartment |
| C．halfway home | D．in front of her apartment ? |
The underlined word "this" in the last
paragraph probably refers to ____．
| A．not doing anything to help | B．behaving in correct ways |
| C．taking action | D．murdering |
We can learn from the passage that Genovese's neighbors didn't lend a hand partly because they ____．
| A．were afraid of being attacked by the murderer |
| B．thought someone else might come to her rescue． |
| C．didn't get along well with her |
| D．were sure it was murdering |
The sandstorm has a bad effect on human beings, but it also brings some good results. There wouldn’t have been our Chinese nation if there had been no sandstorms. Sandstorms have existed for millions of years, while the written history of human beings has lasted only 5,000 years. The Loess Plateau(黄土高原) was formed by sandstorms over millions of years. The Yellow 
River, while moving through the Loess Plateau, carries a great deal of sand and has formed the North China Plain. The Loess Plateau is regarded as the place where Chinese civilization(文明) began. If there had been no Loess Pla
teau, the North China Plain wouldn’t have existed, nor would have the Chinese civilization.
Sandstorms don’t bring only loess to human beings. When sandstorms move from central Asia to the Pacific regions, they carry some minerals into the a
ir, which will later fall into the ocean in the form of rain. The minerals will help some planktons(浮游生物) to survive. The planktons are eaten by small shellfish, and fish live on these small shellfish, and fish are eaten by humans. This forms a biological chain which shows a relation between humans and nature.
So it is unrealistic to say we should stop sandsto
rms. What we can possibly do is to reduce their bad influence as much as we can.
1. The underlined sentence in the first paragraph probably means _________.
A. there are many sandstorms in China
B. the land of China was made by sandstorms

2. Ho
w does the sandstorm help to form the biological chain?
A. The sandstorm carries lots of rain into the ocean.
B. The sandstorm helps some minerals fall into the ocean.
C. Some minerals directly fall into the ocean in the form of rain.
D. The sandstorm moves from central Asia to the Pacific regions.
3. The writer thinks that _______.
A. the sandstorm only has a bad effect on human beings
B. sandstorms bring about lots of trouble, but we can still make use of them
C. without sandstorms, there would be no Chinese civilization and human beings
D. sandstorms play an active role in the Chinese civilization, so we should protect them
4. The text mainly talks about _______.
A. the history of sandstorms B. what the biological chain is
C. how the Loess Plateau formed
D. the good effects of sandstorms

Online shopping started not so long ago. Tim Berners-Lee invented the World Wide Web in 1990. The first online bank opened in 1994. In 1995, Amazon started operating and is now one of the largest online shopping malls. Then in 1996, eBay started its online shopping site.
By sitting at home you can now buy anything from knives to cars. The worry you may have about traveling and parking can be avoided while you shop online. With online shopping, you need not worry about the weather. Online shops have no holidays, closing times or any other problems. You can shop 24 hours a day, 7 days a week and 365 days a year. Some online shops also keep customers’ opinions about each product, so you can easily find out what other customers think about the product before buying it.
When you go for real-world shopping, you can actually touch and feel it, but in online shopping you can only see the pictures. Also if you are shopping online, you have to be careful with your credit cards.
The first step in online shopping is to search for what you want to buy. Once you find the required product, put it in a “shopping cart” and continue shopping. After you have got enough in your “shopping cart”, check out the product. You can add or take out the products in your shopping cart. The next step is to login(登录) using a username and a password. Enter the address where you want the product to be sent. Some sites even ask for your email, phone numbers, etc. Then wait for the confirmation(确认)of your order. You can also cancel the order if needed. Online shopping is a different experience and you can make shopping online easy when you get used to it.

IV.阅读理解：（共32分，每小题2分）
Can you imagine your doctor warning that taking a bath could be unhealthy? In the early 1800s, many doctors thought that bathtubs(浴缸) could carry diseases, so they advised against their use. The advice wasn’t based on personal experience, because few of the doctors owned bathtubs. The White House did not even have a bathtub until 1851.
In the 19th century, only one home out of six had a bathroom. A child took only one bath a week. On Saturday nights, children all lined up for their turns to wash in a wooden bathtub in the kitchen. Mothers had to boil the water on the stove and carry it over to fill the bathtub. It’s no wonder that children could not jump into a bathtub as they do today.
When the first bathtubs were introduced, even their makers weren’t sure whether the new fashion would last. They advertised their products as water containers that “could be used as bathing tu
bs”.
The bathtub became popular in America shortly after World War I. By then most middle-class families had indoor taps. At first most bathtubs 
were made of wood, but as the popularity of the product increased, so did the creativity of bathtub makers. Before porcelain(瓷) bathtubs there were rubber o
nes like the plastic swimming pools kids use today. In the past few years owners often invited guests to see them. They told their friends how wonderful baths in these bathtubs could be.
Now doctors no longer warn that bathtubs carry diseases. Instead, they tell their patients about the benefits of frequent bathing in the bathtubs. Maybe one of the best reasons why doctors 
encourage frequent trips to the bathtub is that bathed patients smell better!
1. Many doctors in the past were against using bathtubs because ______.
A. they didn’t have their own bathtubs
B. they thought bathtubs could carry diseases.
C. the children might hurt themselves in the bathtubs
D. bathtubs were too expensive for the common families
2. Why couldn’t children jump into a tub in the 19th century as they do today?
A. It was unhealthy to do so. B. The bathtubs were not enough.
C. Mothers were always busy. D. The bathtubs were made of wood.
3 .Which of the following is true according to the text?
A. Some different materials can be used to make bathtubs.
B. In the 19th century only one home out of seven had a bathroom.
C. The bathtub became popular when they were introduced to the market.
D. Children prefer the bathtubs made of plastic to those made of porcelain.
4. It can be inferred from the last paragraph that ______.
A. all the doctors have bathtubs in their homes
B. the doctors have realized the advantages of bathtubs
C. the doctors will make lots of money by advertising 
bathtubs
D. the patients should take a bath before going to see a doctor
Try this little test. A man dressed completely in black is sitting at a bar in a country pub. He is drinking one whisky after another. After three hours, the man in black leaves the pub and walks drunkenly down a small country road. There are no lights, and there is no moon. A car without headlights approaches. The driver notices the man, however, and is able to brake in time to avoid an accident. How could the driver see the man in black? Think about this.
The reason we can get stuck with this – and other problems in life—is that we make assumptions. If we assume that the man in black is out for an evening drink, then the problem is a hard one to solve.
The dictionary describes an assumption as something we take for granted or suppose to be true. Assumptions are essential to logical thinking and decision-making, but what happens if they are false?
Sometimes false assumptions can lead to disaster. On 8 January 1989, a British Midland Airways Boeing took off from Heathrow for Belfast. The number-two (right) engine, which had caused trouble on the previous flight, had been cleared. Twenty minutes after take-off, the plane began to shake violently. The flight recorder later showed what had happened. The captain asked the co-pilot what the problem was. “It’s the f-ing right engine again!” he replied. The captain ordered no.2 engine to be shut down, and the lefthand (no.1) engine to be turned on for an emergency landing. The 737 crashed on the edge of the M1 motorway. The cause of the crash? The captain and copilot made a false assumption and shut down the wrong engine. Of the 118 passengers, 39 died and 74 suffered serious injury.
The more risky or the more expensive the decision, the more important it is to check assumptions. There is a nice way to remember the importance of assumption checking. Look at the letters in the word ASSUME, and note that taking things for granted can make an ASS（傻瓜） of U and ME.
