Kicking the Habit
What is a bad habit? The most common definition is that it is something that we do regularly, almost without thinking about it, and which has some sort of negative consequence. This consequence could affect those around us, or it could affect us personally. Those who deny having bad habits are probably lying. Bad habits are part of what makes us human.
Many early habits, like sucking our thumb, are broken when we are very young. We are either told to stop doing it by our parents, or we consciously or subconsciously observe that others do not have the same habit, and we gradually grow out of it. It is when we intentionally or unintentionally pick up new habits in our later childhood or early adulthood that it becomes a problem. Unless we can break that habit early on, it becomes “programmed” into our brain.
A recent study of human memory suggests that no matter how hard we try to change our habits, it is the old ways that tend to win, especially in situations where we are rushed, stressed or overworked. Habits that we thought we had got rid of can suddenly come back. During the study programme, the researchers showed a group of volunteers several pictures, and gave them words to associate with them. They then showed the volunteers the same pictures again, and gave them new words to associate with them.
A few days later, the volunteers were given a test. The researchers showed them the pictures, and told them to respond with one of the words they had been given for each one. It came as no surprise that their answers were split between the first set of words and the second. Two weeks later, they were given the same test again. This time, most of them only gave the first set of words. They appeared to have completely forgotten the second set.
The study confirms that the responses we learn first are those that remain strongest over time. We may try to change our ways, but after a while, the response that comes to mind first is usually the first one we learned. The more that response is used, the more automatic it becomes and the harder it becomes to respond in any other way.
The study therefore suggests that over time, our bad habits also become automatic, learned behaviour. This is not good news for people who picked up bad habits early in life and now want to change or break them. Even when we try to put new, good intentions into practice, those previously learned habits remain stronger in more automatic, unconscious forms of memory.
16．Boys usually develop bad habits when they are very young.
A．Right B．Wrong C．Not mentioned
17．We can only break bad habits if others tell us to do so.
A．Right B．Wrong C．Not mentioned
18．Bad habits may resume when we are under pressure.
A．Right B．Wrong C．Not mentioned
19．Researchers were surprised by the answers that the volunteers gave in the first test.
A．Right B．Wrong C．Not mentioned
20．The volunteers found the test more difficult when they did it the second time.
A．Right B．Wrong C．Not mentioned
21．The study suggests that it is more difficult to respond to what we learn first.
A．Right B．Wrong C．Not mentioned
22．If we develop bad habits early in life, they are harder to get rid of.
A．Right B．Wrong C．Not mentioned

Pedestrians Only
1　The concept of traffic-free shopping areas goes back a long time. During the Middle Ages, traffic-free shopping areas were built in Middle Eastern countries to allow people to shop in comfort and, more importantly, safely. As far back as 2,000 years ago, road traffic was banned from central Rome during the day to allow for the free movement of the pedestrians, and was only allowed in at night when shops and markets had closed for the day. In most other cities, however, pedestrians were forced to share the streets with horses, coaches and, later, with cars and other motorized vehicles.
2　The modern, traffic-free shopping street was born in Europe in the 1960s, when both city populations and car ownership increase rapidly. Dirty gases from cars and the risks involved in crossing the road were beginning to make shopping an unpleasant and dangerous experience. Many believed the time was right for experimenting with car-free streets, and shopping areas seemed the best place to start.
3　At first, there was resistance from shopkeepers. They believed that such a move would be bad for business. They argued that people would avoided streets if they were unable to get to them in their cars. When the first streets in Europe were closed to traffic, there were even noisy demonstrations, as many shopkeepers predicted they would lose customers.
4　However, research carried out afterwards in several European cities revealed some unexpected statistics. In Munich, Cologne and Hamburg, visitors to shopping areas increased by 50 percent. On Copenhagen’s main shopping street, shopkeepers reported sales increases of 25-40 percent. Shopkeepers in Minneapolis, the USA, were so impressed when they learnt this that they even offered to pay for the construction and maintenance costs of their own traffic-free streets.
5　With the arrival of the traffic-free streets, many shops, especially those selling things like clothes, food and smaller luxury items, prospered. Unfortunately, it isn’t good news for everyone, as shops selling furniture and larger electrical appliances who actually saw their sales drop. Many of these were forced to move elsewhere, away from the city centre.

23．Paragraph 1 _____
24．Paragraph 2 _____
25．Paragraph 3 _____
26．Paragraph 4 _____

A．Facing protest from shop owners
B．Increase in sales and customers
C．An idea from ancient history
D．A need for change
E．An experiment that went wrong
F．Popularity of online shopping

27．Traffic-free shopping streets first developed in ________.
28．In the 1960s, dirty gases from cars made shopping ________.
29．Shopkeepers mistakenly believed that car-free streets would keep away ________.
30．The arrival of the traffic-free shopping street made many ________ lost their business.

A．customers
B．pedestrians
C．furniture sellers
D．Middle Eastern countries
E．a bad experience
F．North America

第4部分：阅读理解（第31～45题，每题3分，共45分）
下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。
第一篇 An Expensive Mistake
Is there water on the planet Mars? Is there life on Mars? Was there ever life on Mars? Scientists from NASA wanted to know the answers to these questions. They built a spacecraft to travel around Mars and get information. The spacecraft was called the Mars Climate Orbiter.
The Mars Climate Orbiter left for Mars on December 1998. The trip took nine and a half months. At first, everything was fine. However, when the Orbiter got near Mars, something terrible happened. The spacecraft didn’t go to the right place. It went too close to Mars. It was too hot for the Orbiter there. The spacecraft couldn’t function correctly. Suddenly, it stopped sending messages to NASA．The Orbiter was lost.
How could this terrible thing happen? How did the Orbiter get closer to Mars than the scientists planned? Finally, they found the answer. Two teams of scientists worked together on the Orbiter. One team was in England, and one team was in the United States. There were many similarities in the way they worked, but there was one important difference: The teams used different guidelines for measuring things. The United States team used the metric system（公制）. The other team used the English system.
Because they used different systems, the scientists made a mathematical mistake. The Orbiter’s orbit (the shape and pattern of its path) around Mars was not correct. The scientists put the Orbiter on the wrong path. The Orbiter got too close and too hot, and it stopped functioning.
Why didn’t anybody see the mistake before it was too late? Many things contributed to the problem. One thing was that NASA scientists and mathematicians were working on two other spacecrafts at the same time. This was a challenge, and they were very tired from working long hours.
The Mars Climate Orbiter cost $94 million to build. It also cost a lot of money to try to find the lost Orbiter in space. In addition, NASA’s research on the cause of the problem was expensive. This wasn’t the first time that two different measurement systems caused mistakes in scientific projects. However, the Mars Climate Orbiter was definitely the most expensive mistake of all!
31．NASA built the Mars Climate Orbiter to get information about
A．possible life on Mars
B．the size of Mars.
C．the shape of Mars.
D．the atmosphere of Mars.
32．How long did it take the Orbiter to get close to Mars?
A．One year.
B．Less than one year.
C．About two and a half years.
D．More than three years.
33．When did the Orbiter’s problem begin?
A．Right after it left for Mars.
B．Right after it landed for Mars.
C．When it got near Mars.
D．When it returned to Earth.
34．What caused the Orbiter’s problem?
A．Scientists used wrong guidelines of mathematics.
B．Scientists used wrong building materials.
C．Scientists used different measurement systems.
D．Scientists used different operating systems.
35．Why didn’t NASA scientists identify the problem before the Orbiter left for Mars?
A．They didn’t know the English system.
B．They were tired from working long hours.
C．They were sure of the success of the trip.
D．They didn’t get enough research funding.

第二篇 The Development of Ballet
Ballet is a dance form that has a long history. The fact that it survives to this day shows that it has adjusted as times have changed.
Ballet began in the royal courts during the Renaissance. At that time it became common for kings and queens, as well as other nobility, to participate in pageants that included music, poetry, and dance. As these entertainments moved from the Italian courts to the French ones, court ladies began participating in them. Though their long dresses prevented much movement, they were able to perform elaborate walking patterns. It was not until the 1600s that women dancers shortened their skirts, changed to flat shoes, and began doing some of the leaps and turns performed by men.
It was also in the 1600s that professional ballet began. King Louis XIV of France, himself a devoted dancer, founded the Royal Academy of Dance. The five basic feet positions from which all ballet steps begin were finalized. In the late 1700s another important change occurred. Ballet began to tell a story on its own. It was no longer simply dance to be performed between acts of plays. Elaborate wigs and costumes were eliminated. By the early 1800s dancers to rise on their toes to make it appear that were floating.
Classical ballet as we know it today was influenced primarily by Russian dancing. The Russians remained interested in ballet when it declined in other European countries in the mid-1800s. One of the most influential figures of the early 20th century was Sergei Diaghilev. His dance company, the Ballets Russes, brought a new energy and excitement to ballet. One of his chief assistants, George Balanchine, went on to found the New York City Ballet in 1948 and to influence new generations of dancers.

A．famous names in ballet.
B．Russian ballet.
C．how ballet has developed.
D．why ballet is no longer popular.

C．royal courts.
D．big shows.
38．Professional ballet was first performed in
A．Italy..
B．France
C．Russia.
D．America.
39．Who had an important influence on early ballet?
A．Balanchine.
B．Antoinette.
C．Diaghilev..
D．Louise ⅪⅤ
40．We can conclude from this passage that ballet
A．is a dying art.
B．will continue to change.
C．is currently performed only in Russia.
D．is often performed by dancers with little training.

第三篇 Operation Migration
If you look up at the sky in the early fall in the northern part of North America, you may see groups of birds. These birds are flying south to places where they can find food and warmth for the winter. They are migrating（迁徙）. The young birds usually learn to migrate from their parents. They follow their parents south, in one unusual case, however, the young birds are following something very different. These birds are young whooping cranes, and they are following an airplane!
The young whooping crane is the largest bird that is native to North America. These birds almost disappeared in the 1800s. By 1941, there were only about 20 cranes alive. In the 1970s, people were worried that these creatures were in danger of disappearing completely. As a result, the United States identified whooping cranes as an endangered species that they needed to protect.
Some researchers tried to help. They began to breed whooping cranes in special parks to increase the number of birds. This plan was successful. There were a lot of new baby birds. As the birds became older, the researchers wanted to return them to nature. However, there was a problem: These young birds did not know how to migrate. They needed human help.
In 2001, some people had a creative Idea. They formed an organization called Operation Migration. This group decided to use very light airplanes, instead of birds, to lead the young whooping cranes on their first trip south. They painted each airplane to look like a whooping crane. Even the pilots wore special clothing to make them look like cranes. The cranes began to trust the airplanes, and the plan worked.
Today, planes still lead birds across approximately 1,200 miles (1,931 kilometers), from the United States-Canadian border to the Gulf of Mexico. They leave the birds at different sites. If a trip is successful, the birds can travel on their own in the future. Then, when these birds become parents, they will teach their young to migrate. The people of Operation Migration think this is the only way to maintain the whooping crane population.
Operation Migration works with several other organizations and government institutes. Together, they assist hundreds of cranes each year. However, some experts predict that soon, this won’t be necessary. Thanks to Operation Migration and its partners, the crane population will continue to migrate. Hopefully, they won’t need human help any more.
41．Whopping cranes migrate in winter to
A．raise baby whooping cranes.
B．find warmth and food.
C．get human help.
D．lay eggs.
42．Whopping cranes are native to
A．Mexico.
B．South America.
C．the Persian Gulf
D．North America.
43．Operation Migration aims to
A．teach adult cranes how to fly.
B．breed cranes in special parks.
C．lead young cranes on their first trip south.
D．transport cranes to the North.
44．The distance covered by the young whooping cranes on their trip south is
A．120 miles.
B．1,200 miles
C．1,931 miles
D．2,000 miles
45．If Operation Migration is successful, whooping cranes will
A．follow airplanes south every year.
B．live in Canada all year round.
C．be unable to fly back.
D．learn to migrate on their own.

52　A　原文意思是“地球温度的升高”，此处的介词表示的是从属关系，四个选项中只有A项表示一定的从属关系，其余三个都不行。
53　C　that引导宾语从句，不要受到后面插人语的干扰。
54　C　at risk是固定搭配，表示“受到威胁，处于危险中”。
55　D　此处的them指代的是前一个句子开头的many scientists。
56　A　such as“例如”。
57　B　科学家认为，全球变暖使得极端天气更加严重，even more前面的短句是插人语，分析句子成分的时候可将其去掉，会更容易看出。
58　C　根据句义，此处应该是“引起海平面上升”，raise一般表示“举起，抬起”，如：Would all those in favour please raise their hands？赞成的人请举手好吗？rise指“上升，升起”，如：The balloon rose gently into the air.气球慢慢升人空中。in常指“举起，提起”，如：Could you help me lift this table, please？你能帮我抬一下桌子吗？
59　D　句子意思为：环保组织正对政府施加压力。put pressure on someone“对某人施加压力”。
60　A　amount指不可数名词的数量；deal也指不可数名词的数量，但前面常加形容词，如a good/great deal of; number指可数名词的数量；count的意思是“计数，总数”，指可数名词，如：Early vote counts show Mr. Adams in the lead.早先的计票显示亚当斯先生领先。
61　B　此处表示因果关系。
62　C　in favour of是固定搭配，意思是“赞成、支持某人”。
63　D　环保组织支持增加太阳能、风能和潮汐能电站以代替现存的电站，replace意为“代替”。
64　D　最后一段的观点与前文不同，这句表示转折，因此用however。
65　B　句子的意思是：即使我们现在停止向大气中排放二氧化碳和其他气体，可能也需要好几百年我们才能看到结果。
