conversations and interrupting your sleep, you can call the police. But what is a whale to do?
Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately,
man-made noise from oil and gas drilling, sonar, and ships is also present.
Low frequency noise has doubled off the California coast every decade since the nineteen sixties.
The main reasons are ships" propellers (螺旋桨). They not only generate continuous low frequency
sound, some propellers cavitate (形成气穴), which means they create air bubbles that collapse,
creating loud popping sounds.
Whales use low frequency calls to communicate across thousands of miles of ocean. They are
threatened by noise pollution because it can prevent them from contacting each other and from locating
their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the
water, are the most at risk.
Scientists studying right whales off Canada"s east coast have discovered that whales are sending
louder calls through the water to make themselves heard. Because they invest more energy in making
calls, they have less energy available for finding food and mating. Other scientists measuring whale calls
against background noise pollution have discovered that right whales have lost about eighty percent of
their normal communication area. This could seriously affect survival of this already threatened species.
Scientists don"t have badges and guns, but they are trying to correct the noise pollution problem. By
tracking ships and marine mammals and understanding how noise travels, they are creating sound maps.
They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas
most important to the whales.
C. Natural noise is good for whales.D. How to protect whales endangered.
B. Low frequency noise has doubled off the Canadian coast every decade since 1960s.
C. Noise pollution can prevent whales from contacting each other and from locating prey.
D. Endangered humpback and right whales are the most at risk.
B. Scientists are creating the sound maps by tracking ships and marine mammals.
C. If scientists have guns, they can correct the noise pollution.
D. Scientists have worked out a plan to protect the whales.
B. Right whales cannot find food and mate for they lose a lot of living area.
C. There are about 20% of the normal communication areas still available for the right whales.
D. The right whales always invest most of their energy for making calls.
B. Whales can communicate with each other by diving into the deep water.
C. Whales cannot find mates because they don"t have enough energy.
D. The communication between whales is through low frequency calls

Fukushima (Japan) last year the issue is back in the headlines. And the world is divided- some countries
are planning more nuclear plants, while others have promised to shut theirs down.
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy
are also phasing out nuclear power. But France and the United States remain staunch supporters of
atomic energy. In fact, almost 80% of France"s electricity comes from nuclear power, the highest
percentage in the world. And in the US, the Obama administration said it "continues to support the
expansion of nuclear power, despite the crisis in Japan."
Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power
doesn"t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to
generate energy without contributing to climate change. Britain"s chief scientific adviser (John Beddington)
supports this view. He recently said that the world doesn"t have the luxury of ignoring nuclear energy.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind
power may be clean, but they"re expensive; and right now, they require a lot of investment. This higher
cost of using "green energy" is usually passed onto the consumer. So, while many people may prefer their
energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of
particular concern while the world economy is in such bad shape.
The main argument against nuclear energy is that it isn"t safe. For a start, nuclear waste is very difficult
to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there
were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in
the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
The nuclear energy issue is very complex. And it doesn"t look like it"ll be resolved anytime soon. As a
Japanese commentator recently said, "it"s been a bad year for the "nuclear village", but I don"t think they"re down and out yet." The battle continues.
B. The cost of using renewable sources
C. The fact that the nuclear power is cheaper.
D. The investment of renewable energy sources
B. explain that nuclear waste may remain harmful to humans for thousands of years.
C. persuade the world not to use nuclear energy.
D. support the idea that nuclear energy is not safe.
B. the nuclear energy issue will be soon settled.
C. a battle will break out in the future.
D. Japan is considering to build a nuclear village in the future.
B. To introduce some serious nuclear disasters.
C. To show the argument between nuclear supporters and protesters.
D. To give some advice on how to use nuclear energy safely.
depends on his home life and his relationships with the people who love him. Children in large families
learn how to get along with others through normal brother- sister play and tussles (打斗). An only child,
on the other hand , may have to learn his lessons in social living through hard experiences on the
playground or in the classroom. Twins who always have one another to lean on may be slow in
responding to others because they do not need anyone else.
A child who is constantly scolded and made to feel he does everything wrong may have a difficult
time developing socially. He may be so afraid of displeasing the adults around him that he keeps to
himself (where he can"t get into trouble)or he may take the opposite route and go out of his way to create
trouble. Like the deserted child, he too may return to infantile (幼稚的) pleasures, developing habits that
will satisfy him, but create barriers (障碍) toward social contact.
B. Education
C. Home life.
D. Gender (性别)
B. All children developed in the same ways.
C. Children who are constantly scolded may learn to get along with others quickly.

D. All of the above
have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite
different ideas about how to teach it, or how much priority (优先) it must be given over general language
development and writing ability. The problem is how to encourage a child to express himself freely in
writing without holding him back with spelling.
If spelling becomes the only point of his teacher"s interest, clearly a bright child will be likely to "play
safe". He will write only words within his spelling range. That"s why teachers often encourage the early
use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism of
the pupils" technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略过)
to read the composition, which contained some beautiful expressions of the child"s deep feelings. The
teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child"s
ideas, an expression of his disappointment with the presentation would have given the pupil more hope to
seek improvement.
B. the necessity of teaching spelling
C. the importance of the basic writing skills
D. the role of spelling in general language development
B. to avoid using words one is not sure of
C. to use dictionaries frequently

C. the correct way of marking composition
D. the relationship between spelling and the content of a composition
Violence and traffic accidents can leave people with terrible physical and emotional scars. Often the
experiences in nightmares appear repeatedly.
Now American researchers think they are close to developing a pill, which will help people forget
bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it
might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body
releasing chemicals that fix memories in the brain. So far, the research has suggested that only the
emotional effects of memories may be reduced, not that the memories are wiped out. They are not
sure to what degree people"s memories are affected.
The research has caused a lot of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers" troubling memories after war. They
say that there are many people who suffer from terrible memories.
"Some memories can ruin people"s lives. They come back to you when you don"t want to have them
in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a
professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that maybe the pills can change people"s memories and
changing memories is very dangerous because memories give us our identity. They also help us all avoid
the mistakes of the past.
"All of us can think of bad events in our lives that were terrible at the time but make us who we are.
I"m not sure we want to wipe those memories out." said Rebecca Dresser, a medical ethicist (伦理学家).
B. a new research on the pill
C. an argument about the research on the pill
D. a way of wiping out painful memories
B. stop people remembering bad experiences
C. wipe out the emotional effects of memories
D. prevent body producing certain chemicals
B. the pill will certainly stop people"s emotional memories
C. taking the pill will do harm to people"s physical health
D. the pill has already been produced and used by the public America
B. people want to get rid of bad memories.
C. experiencing bad events makes us different from others.
D. the pill will reduce people"s sufferings from bad memories.
B. a textbook
C. a medical magazine
D. a science fiction
not forced, to "leave the nest" and begin an independent life. After children leave home, they often find
social relationship and financial support outside the family. Parents do not arrange marriages for their
children, nor do children usually ask permission of their parents to get married. Romantic love is most
often the basis for marriage in the United States; young adults meet their future spouses (配偶) through
other friends, at jobs, and in organizations and religious institutions. Although children choose their own
spouses, they still hope their parents will approve of their choices.
In many families, parents feel that children should make major life decisions by themselves. A parent
may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do exactly the opposite of what their parents wish in order to be independent. A son
may decide not to go into his father"s business on purpose because of a fear that he will lose his
autonomy(自主) in his father"s workplace. This independence from parents is not an indication that
parents and children do not love each other. Strong love between parents and children is universal and
this is no exception in the American family. Coexisting (共存) with such love in the American family are
cultural values of self - reliance and independence.
B. They want to win the permission of their parents.
C. They enjoy the freedom of choosing their spouses.
D. They want to challenge the authority of their parents.
B. financial concern
C. love
D. family background
B. most American people never make major decisions for their children
C. American young adults possess cultural values of independence
D. once a young person steps into his twenties, he will leave his home permanently
B. he wants to prove his independence
C. he wishes to do the opposite of what his parents approve of
D. he wants to show his love for his parents
B. marriage arrangements
C. the pursuit of a career
D. decision making
