Passage 1
Body color is of great importance for many animals. For example, the stripes of a zebra and the
spots of a giraffe make them look very surprising in zoo. But if you saw them in Africa against a
background of trees with the sunlight going through the leaves, then you would be greatly
surprised how difficult they are to see, for they seem to be mixed into the background.
This is called protective coloration, for it protects the animal from its enemies by making
itself more difficult to be seen. You can see this protective coloration in many kinds or animals.
The angel fish, for example, is striped like a zebra so that it becomes almost invisible against the
background of the red stems in the streams of very hot areas. Another fish that has wonderful
protective coloration is the common plaice(比目鱼). This remarkable flat fish can change the
color of its body so that it can suit whatever type of ground it is lying on.
The chameleon (变色龙) is a famous for its protective coloration, for it can change its body
colors as it walks from a tree onto a branch with green leaves. You can see it turn green as you
watch. In this case, of course, its ability to match its surroundings serves two purposes: protecting
it from its enemies and making it nearly impossible to be seen by insects on which it feeds.
1. What is the main purpose of this passage?
A. It is to tell people to protect animals.
B. It is to explain how animals change their colors.
C. It is to introduce the function or animals' body color.
D. It is to tell readers that the world is full of varieties
2. Body color is important for animals because________.
A. they like to be different from each other depend upon it for survival
C. it presents a colorful picture D. it is part of the wild life
chameleon is well-known for its________.

C . technique in catching insects D. ability to go from place to place quickly.
4. Which of the following statements is NOT true according to the passage?
A. Protective coloration can help animals to get food.
B. The plaice can change its color into one similar to the ground.
C. Protective coloration can protect animals from their enemies.
D. You can easily see a zebra in Africa because of its stripes.
5. How many animals that can change body color are mentioned in the passage?
A. 2 B. 3 C. 4 D. 5

Passage 2
Our minds may wander during boring tasks because daydreaming is actually the brain's
normal state, rather than a pointless distraction, according to a new U.S. study.
The researchers, reporting their findings today in the U.S. journal, Science, found that
daydreaming could be the result of the brain thinking over important—but not immediately
relevant—issues when the external environment ceases to pose interesting and engaging problems.
―For the most part psychologists have sort of assumed that we spend most of our time
engaged in goal-directed thought and that, every so often, we have blips (光点) of irrelevant
thoughts that pop up on the radar,‖ said Malia Mason of Harvard University. ―However, it could
very well be the case that most of the time we are engaged in less directed, unintended thought
and that this state is routinely interrupted by periods of goal-directed thought.
Daydreaming or mind- wandering is more precisely defined as a state of mind where thoughts
that are experienced by an individual are unrelated to what is going on in the environment around
them, according to Mason. When wandering, the brain flits from one thought to the next,
generating images, voices, thoughts and feelings.
When deciding how best to encourage daydreaming in order to study it, the researchers
recognized that our minds often wander while we are engaged in familiar tasks, such as making a
sandwich, because we don't need to concentrate on it. They trained study subjects to become
proficient on certain tasks so that their minds would be able to wander when they performed them,
but would have to concentrate when given something new.
1. According to the new US study mentioned in the passage, daydream happens when
___________.
A. the brain thinks over important but temporarily irrelevant things
B. the external environment stops posing interesting and engaging problems
C. the brain generates images, voices, thoughts and feelings
D. both A and B.
2. According to Mason, we spend most of our time engaged in___________.
A. goal-directed thought B. less directed and unintended thought
C. very important thought D. none of the above
3. In order to study daydream, researchers ___________.
A. encourage study subjects to daydream
B. ask study subjects to make sandwiches
C. train study subjects to become proficient on certain tasks
D. help study subjects concentrate on certain tasks
4. Which of the following statements is TRUE according to this passage?
A. Daydream is a meaningless distraction away from the brain’s normal state.
B. Daydream researchers find that one cannot concentrate on familiar tasks.
C. During daydreaming, thoughts flash through the brain one after another, producing
images and voices and feelings.
D. Mason shares the same opinion with most psychologists.
5. The passage is most probably from _____________.
A. a science magazine B. a medical textbook
C. a personal letter D. a government document

Passage 3
The city has always been an engine of intellectual life, from the 18th-century cafes of London,
where citizens gathered to discuss chemistry and politics, to the Left Bank bars of modern Paris,
where Picasso talked about modem art. Without the metropolis, we might not have had the great
art of Shakespeare.
And yet, city life isn’t easy. Now scientists have begun to examine how the city affects the
brain, and the results are depressing. Just being in an urban environment, they have found, impairs
(损害) our basic mental processes. After spending a few minutes on a crowded city street, the
brain is less able to hold things in memory, and suffers from reduced self-control. While it’s long
been recognized that city life is exhausting, this new research suggests that cities actually dull our
thinking, sometimes dramatically so.
One of the main forces at work is a complete lack of nature, which is surprisingly beneficial
for the brain. Studies have demonstrated, for instance, that hospital patients recover more quickly
when they can see trees from their windows, and that women living in public housing are better
able to focus when their apartments overlook a lawn. Even these glimpses of nature improve brain
performance, it seems, because they provide a mental break from the urban life.
This research arrives just as humans cross an important milestone (里程碑). For the first time
in history, the majority of people live in cities. Instead of inhabiting wide-open spaces, we’re
crowded into concrete jungles, surrounded by traffic and millions of strangers. In recent years, it’s
become clear that such unnatural surroundings have important implications for our mental and
physical health, and can powerfully alter how we think.
1. Which of the following is the main idea of this passage?
A. The city inspires talented people.
B. The city hurts your brain.
C. The city has many pleasures and benefits.
D. The city seriously affects the natural balance.
2. The word ―metropolis‖ in the first paragraph is closest in meaning to_______.
A. citizen B. nature C. city D. stress
3. People have just come to realize that_______.
A. human attention is a scarce resource
B. city life can make people very tired
C. the city is an engine of intellectual life
D. an urban environment is damaging to the brain
4. What is the factor mentioned in the third paragraph that helps the hospital patients recover more
quickly?
A. Nature. B. Better treatment.
C. Experienced doctors. D. Good medicine.
5. According to the passage, which of the following statements is TRUE?
A. Different aspects of an urban environment, such as the crowded streets, can lead to
an increase in self-control.
B. Small changes in urban design cannot reduce the negative side effects of city life.
C. For the first time in history, the earth’s population is more urban than rural.
D. A walk down a busy city street will improve brain performance.

Passage 1
The economy of the United states after 1952 was the economy of a well-fed, almost fully
employed people. Despite occasional alarms, the country escaped any postwar liquidation (清
算)and lived in a state of boom. The history of extraction, production, and distribution had
therefore been almost nothing but a statistical (统计的) table reflecting prosperity.
An economic survey of the year 1955, a typical year of the 1950’s, may be typical as
illustrating the decades. The national output was valued at about 10 percent above that of 1954
(1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40
percent more than it had averaged in the years immediately following World War II. The country’s
business spent about 30 billion dollars for new factories and machinery. National income available
for spending was almost a third greater than it had been in 1950. Consumers spent about 256
billion dollars; that is, about 700 million dollars a day ,or about twenty- five million dollars every
hour , all round the clock. Sixty-five million people held jobs and only a little more than two
million wanted jobs but could not find them.
Only agriculture complained that it was not sharing in the room. To some observers this was
a vicious (危险的) echo of the mid-1920’s . As farmers’ share of their products declined,
marketing costs rose.

A. The agricultural trends of the 1950's.
B. The unemployment rate in 1955.
C. The general economic situation in the 1950's.
D. The federal budget 0f 1952.
2. In the first paragraph, the word “boom
explosion B. general public support
C. thunderous noise D. rapid economic growth
3. The passage states that income available for spending in the U.S. was approximately ________
greater in 1955 than in 1950.
A. 33% B . 50% C . 66% D. 90%
4. It can be inferred from the passage that most people in the U.S. in 1955 viewed the national
economy with an air of________.
A. optimism B. confusion y D. suspicion
5. Which of the following statements about the 1950s in the United States is NOT true?
A. The unemployment rate was very low.
B . Farmers' situation was the worst.
C . The government invested a lot of money in manufacturing industry.

Passage 2
It happened in February about twelve years ago. I had left school a couple of months before
that and was not due to go to university until the following October. I was still living at home at
the time.
One morning I was in Richmond, a suburb of London near where I lived. I was looking for a
temporary job so that I could save up some money to go traveling. As it was a fine day and I was
in no hurry, I was taking my time, looking in shop windows, strolling in the park, and sometimes
just stopping and looking around me. It must have been this obvious aimlessness that led to my
downfall.
It was about half past eleven when it happened. I was just walking out of the local library,
having unsuccessfully sought employment there, when I saw a man walking across the road with
the obvious intention of talking to me. I thought he was going to ask me the time. Instead, he said
he was a police officer and he was arresting me. At first I thought it was some kind of joke. But
then another policeman appeared, this time in uniform, and I was left in no doubt.
'But what for?' I asked.
'Wandering with intent to commit an arrestable offence,' he said.
'What offence?' I asked.
'Theft,' he said.
'Theft of what?' I asked.
'Milk bottles,' he said, and with a perfectly straight face too!
'Oh,' I said.
It turned out there had been a lot of petty thefts in the area, particularly that of stealing milk
bottles from doorsteps.
Then I made my big mistake. At the time I was nineteen, had long untidy hair, and regarded
myself as part of the sixties' 'youth counterculture'. As a result, I wanted to appear cool and
unconcerned with the incident, so I said, 'How long have you been following me?' in the most
casual and conversational tone I could manage. I thus appeared to them to be quite familiar with
this sort of situation, and it confirmed them in their belief that I was a thoroughly disreputable
character.
A few minutes later a police car arrived.
'Get in the back,' they said. 'Put your hands on the back of the front seat and don't move
them.'
They got in on either side of me. It wasn't funny any more.
1. At the time the story took place the author was _________.
A. at school B. at college
C. waiting to attend college later that year D. working in the local library
2. He went job-hunting in order that he might earn enough money _________ .
A. to support himself B. to go to university
C. to take a journey D. to hire a good lawyer
3. The first man who came up to him was __________ .
A. a uniformed policeman B. a policeman in plainclothes
C. not a policeman D. a good joker
4. According to the passage, the story took place in _________.
A. London B. Richmond C. local library D. school
5. What does the word intention mean in the third paragraph?
A. purpose B. milk bottle C. belief D. situation


Passage 3
My father was foreman of s sugar-cane plantation in Rio piedras, puerto Rico. My first job
was to drive the oxen that plowed the cane fields. I would walk behind an ox, guiding him with a
broomstick. For $$1 a day, I worked eight hours straight, with no food breaks.
It was very tedious work, but it prepared me for life and taught me many lasting lessons.
Because the plantation owners were always watching us, I had to be on time every day and work
as hard as I could. I’ve never been late for any job since. I also learned about being respectful and
loyal to the people you work for. More important, I earned my pay.
I was only six years old, but I was doing a man’s job. Our family needed every dollar we
could make because my father never earned more than $$18 a week. Our home was a three- room
wood shack with a dirt floor and no toilet. Nothing made me prouder than bringing home money
to help my mother, father, two brothers and three sisters. This gave me self-esteem, one of the
most important things a person can have.
When I was seven, I got work at a golf course near our house. My job was to stand down the
fairway and spot the balls as they landed so the golfers could find them. Losing a ball meant you
were fired, so I never miss one. Some nights I would lie in bed and dream of making thousands of
dollars playing golf and being able to buy a bicycle.
The more I dreamed, the more I thought, why not? I made my first golf club out of guava
limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I
dug two small holes in the ground and hit the ball back and forth. I practiced with the same
devotion and intensity I learned working in the field – except now I was driving golf balls with
club, not oxen with a broomstick.
1. What was the writer’s first job?
A. To stand down the fairway at a golf course.
B. To spot the balls as they landed so the golfers could find them.
C. To drive the oxen that plowed the cane fields.
D. To watch the sugar-cane plantation.
2. The word “tedious” in paragraph 2 most probably means ____.
A. hard B. boring C. interesting D. long
3. What did the writer learn about from his first job?
A. He could work as hard as possible.
B. He could go to work on time.
C. He should never fail to go to work.
D. He should be respectful and loyal to the people he works for.
4. What gave the writer self- esteem?
A. Having a big family. B. Bringing money back home to help the
family.
C. Helping his father with the work. D. All of the above.
5. What was the writer’s dream while working at a golf course?
A. Making a lot of money by playing golf. B. Becoming a successful golfer.
C. Running a golf course near his house. D. Both A & B.

5【解析】正确答案是A。根据上下文，那个人穿过马路，很明显是想和我 说话。Intention
意图，与purpose同义。
Passage 3
1、【解析】正确答案B。作者在第一段的第二句提到：My first job was to drive the oxen that
plowed the cane fields.我的第 一份工作便是赶着牛犁甘蔗地。很明显，C符合文章内容；A
守候在高尔夫球场的球道上；B当球着地时 辨认出来，以便高尔夫球手找到他们。在高尔夫
球场的工作虽然作者也做过，但并不是作者的第一份工作 ，故答案为C。
2、【解析】正确答案B。文章第二段开始提到：It was very tedious work, but I prepared me
for life and taught me many lasting lessons.这份工作虽然很令人厌烦，但是使我对生活 做好了
准备，为我上了终身受益的一课.从but一词可以看出这句话明显带有转折的语气，显然
tedious的语气与后面―我‖ 的收获相反，是否定的语气。上文提到，I would walk behind an ox,
guiding him with a broomstick. For $$1 a day, I worked eight hours straight, with no food breaks.
我得在一头牛后面慢慢走，用一根帚柄引导它。一天一美元，我要一直 工作8小时，没有用

money home to help my mother, father, two brothers, and three sisters. This gave me self-esteem,
one of the most important things a person can have.没有什么比拿钱回家帮助我的母亲，父亲，
两个 兄弟和三个姐妹更令我感到骄傲的了。这给我带来了自尊---一个人所能拥有的最重要的
东西之一。很 明显使作者感到自尊的是能赚钱帮助家人。A并非是作者感到自尊的原因；C
也不甚准确；D前面提到的 答案都对，这显然也不符合题目意思。故答案为B。
5、【解析】正确答案D。文章第四段最后提到：Some nights I would lie in bed and dream
of making thousands of dollars playing golf and being able to buy a bicyc le.多少个夜晚我躺在床
