Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分貝)measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
小題1: According to the passage, which of the following is increasingly dangerous to sea creatures?
A.The man-made noises.B.The noises made by themselves.
C.The sound of earthquakes.D. The sound of the ice-breaking.
小題2: Which of the following is discussed in the third paragraph?
A.Different places with different types of noises.
B.The very human ears sensitive to all types of noises.
C.The ocean animals' reaction to noises.
D.The same noise measured differently on land and in the ocean.
小題3:We can know from the passage that many researchers think that the noise limit of one hundred twenty decibels would _____.
A.prevent them from doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output
小題4: According to the passage, what will scientists most probably do in the future?
A.They will try their best to decrease noise.
B.They will work hard to cut down noise pollution.
C.They will study the effect of different noises.
D.They will protect animals from harmful noises.

There is one language that is used in every country in the world. The people who use it are young and old, short and tall, thin and fat. It is everybody’s second language. It is easy to understand, although you can’t hear it. It is sign language.
When you wave to a friend who is across the street, you are using sign language. When you smile at someone, you are saying, “I want to be friendly”, but you are not using speech. You are using sign language. When you raise your hand in class, you are saying, “Please ask me. I think I know the correct answer.”
Babies who can’t talk can point at things. They are using sign language. A policeman who wants to stop traffic holds up his hands. He is using sign language.
Many years ago, a French priest(神父), Charles Michel de Epee, became interested in education for deaf people. He invented a finger alphabet (字母表). It is still in use. People can make the sign for letters and spell words with their hands, and deaf people can read and understand them. Soon there were schools for the deaf in many countries. The only university for the deaf is Gallaudet College in Washington, D.C.
Today, in the United States, there are special TV news programs for deaf people. The newsreader tells the news in sign language. At the same time, the words appear on the TV screen.
The actors in the Theatre of Deaf don’t spell every word. Sometimes they use hand signs. When they put two hands together, it means sandwich. They can make a roof with their hands when they want to show a house. One finger in front of an actor’s mouth can mean quiet. You can talk to people who are behind windows that are closed. And when you go swimming with your friends, you can have conversations under water.

D
Around the globe, the tourist trade is booming and you are promised to enjoy all the comfort and convenience of modern tourism. The first-class systems of communication by air, sea and land make it possible for us to visit each other’s countries at a moderate cost. What was once the ‘grand tour’, reserved for only the very rich, is now within most people’s grasp. The package tour and chartered flights (包機(jī)) are quite popular to us. Modern travelers enjoy a level of comfort which those on grand tours in the old days couldn’t have dreamed of. With all this coming and going, you would expect greater understanding to develop between the nations of the world. Not a bit of it! So what’s the sense of this mass exchange of populations if the nations of the world remain basically ignorant of each other? So there is a great misdirection in tourist business, especially in conducted tour items.
Many tourist organizations are directly responsible for this state of affairs. They purposely set out to “protect” their passengers from too much contact with the local population. Modern tourists lead a protected and separated life. They live at international hotels, where they eats their international food and sips their international drink while gazing at the natives from a distance. Designed tours to places of interest are carefully arranged. The tourists are allowed to see only what the organizers want them to see and no more. A strict schedule makes it impossible for the tourists to wander off on their own; and anyway, language is always a barrier, so they might only be too happy to be protected in this way.
At its very worst, this merely leads to a new and terrible kind of colonization. The sad thing about this situation is that it leads to the persistence of certain old ideas of other nations and countries. We don’t see the people of other nations as they really are, but as we have been brought up to believe what they are, even staying along with that from text books during our schooling.
You can test this for yourself. Take five nationalities, say, French, German, English, American and Italian. Now in your mind, match them with these five adjectives: musical, emotional, cold, pedantic (愛追究的), native. Far from providing us with any insight into the national characteristics of the peoples just mentioned, these adjectives just actually act as barriers, for we can’t do the job with certainty. So, frequently, when you set out on your travels, the only characteristics you notice are those which confirm what you have already obtained as the first conceptions in your mind. And you get home only with the highly unoriginal and inaccurate impression, such as the saying, “Anglo-Saxons are hypocrites (偽君子)” and “Latin peoples shout a lot ”. However, to gain the real understanding, you only have to make a few foreign friends and you will know how ridiculousridiculous ridiculous ridiculous and harmful some old conceptions of other nations are. But how can you make foreign friends when the tourist trade does its best to prevent you?
Being carried to an extreme, stereotypes can be positively dangerous. A very wild and limited outlook may stir up racial hatred and blind us to the basic fact — how reasonless it sounds! – that all people are human. We are all similar to each other, while at the same time all unique.
小題1:What does “grand tour” bring people now?
A.It only offers us reasonable cost.B.It is the best way of modern tourism.
C.It is not liked by rich people.D.It is available for the majority to enjoy it.
小題2:Which of the following is TRUE according to the passage?
A.By travelling abroad, one can know a certain country well.
B.Making friends is impossible for anyone staying abroad.
C.The tourist organizations have the best way to do their duty.
D.Traveling conditions are much more improved than before.
小題3:Which word in the following is the best to summarize “Latin people shout a lot”?
A.Silent.B.Noisy.C.Lively.D.Active.
小題4:The purpose of the author’s writing is to point out ______.
A.conducted tour should be stoppedB.the way of touring should be changed
C.gained knowledge can’t be renewed D.some nations stay the same as before
小題5:What is the author’s attitude toward the present tourism?
A.Objective B.Negative.C.Critical.D.Appreciative.
小題6: The main idea for this passage is that ______.
A.tourism does little to increase understanding between nations

D.tourism really does something wonderful to many countries

Many of us assume that with such a last name, Peter Buffett, 52, must enjoy a life of endless privilege. But the son of billionaire investor (投資人) Warren Buffett definitely doesn’t think so.
“People who are born with a silver spoon in their mouth can fall victim (受害者) to what my father has called a silver dagger (匕首) in your back,” Buffett told Reuters in an interview. “It leads to a sense of entitlement (特權(quán)) and a lack of personal achievement.”
Entitlement, he believes, is the worst thing ever. “Anybody who acts like they deserve (應(yīng)得) something ‘just because’ is a disaster,” he said.
In his new book, Life Is What You Make It: Finding Your Own Path to Fulfillment, Buffett says that the only real inheritance (遺產(chǎn)) handed down from his parents was a philosophy (價值觀): Forge your own path in life. It is a belief that has allowed him to follow his own passions, establish his own identity, and reap (收獲) his own successes.
Did his father ever want him to go into finance? “It was encouraged for a moment when I was open to the idea,” he told Reuters. But as he grew older, it became clear the financial world “was not speaking to my heart.”
His father accepted his choice to become a musician. He began his musical career by writing music for TV commercials (廣告). He then released his own albums.
“I am my own person and I know what I have accomplished in my life,” he told Reuters. “This isn’t about wealth or fame or money or any of that stuff, it is actually about values and what you enjoy and finding something you love doing.”
Along with the book, Buffett has begun a “Concert & Conversation” tour in which he plays the piano, talks about his life and warns against consumerist (消費主義) culture and damaging the environment.
“Economic prosperity (繁榮) may come and go; that’s just how it is,” he writes in the book. “But values are the steady currency (硬通貨) that earn us the all-important rewards.”
小題1: What does “It” in the second paragraph refer to?
A.A life of a top investor. B.A silver spoon in the mouth.
C.Being born to a wealthy family.D.The victim of a silver dagger in the back.
小題2: What does the article tell us?
A.Peter Buffett is a born musician.
B.Peter Buffett enjoys a hugely privileged life.
C.A wealthy family can benefit a child but also spoil him or her.
D.Peter Buffett was forced by his parents to take over their business.
小題3:The article claims that Peter Buffett owes his achievements largely to ______.
A.his passion for music B.the good education he received
C.his great determinationD.the values he learned from his parents
小題4: Which of the following statements would Peter Buffett probably agree to?
A.Wealth is there to enjoy to the fullest.
B.A person’s value lies within.
C.Many people are fooled by economic prosperity.
D.Young people should choose their own philosophy, whatever their parents believe in.

After the U.S. House of Representatives passed a bill aimed at retaliatory(報復(fù)的) action against China for its “significantly undervalued” currency, Treasury Secretary Timothy Geithner urged the IMF to pressure China to adopt “more flexible, more market-directed exchange-rate management”. This is a coded message to China: You’re keeping on purpose your currency cheap, and the U.S. economy is paying the price. So cut it out --- or else. The normally dull IMF meeting became the latest battleground for the U.S. to be against a fast developing China.
Our new conventional wisdom is that China’s policy leads to make trade deficits (逆差) greater and the loss of American jobs. Dozens of candidates have run ads attacking a competitor for allowing China to take advantage of us. In the election-year view, China grew 10% annually for the past decade while maintaining low inflation(通漲) only by taking advantage of its artificially low currency. The idea that the U.S. is not responsible for its own economy is a black-is-white view. It argues that China and its currency are causing the lion’s share of harm.
This is an argument born of fear. It covers a fact that the economies of China and the U.S. have become beneficial to each other. Those trillions in reserves that China accumulates: Where do they go? Back to the U.S. in the form of lending money to the federal government. Those made-in-China goods that account for the trade deficit: Whom do they benefit? China, yes, but also American consumers and companies. Without China, American companies could not have maintained their profitability in recent years. Take two brand names, Caterpillar and Nike. Both have their products made in China, but both also view China as a fast-growing market for their products.
George Soros warned recently that a currency war could put the world into disorder more damaging than anything caused by the financial crisis of the 1930s. He’s right. Whether we like it or not, we live in a global system. The zero-sum attitude toward China and its currency is a relic, the remaining of an earlier time when nations defined economic life.
China is far from perfect and seeks its own advantage, but holding it accountable for our domestic problems is beyond outdated. It reflects a dangerous refusal to deal with the world as it is. Retaliating against China over currency will not regain high-end jobs in the U.S., which needs more our own demand. It will not renew construction or retool the American labor force. It will not rebuild rotting bridges or create a next-generation energy network.
小題1:Which of the following argument can be supported by the writer?
A.China is the winner in the Sino-US trade.
B.China’s rapid development over the past ten years is based on its low inflation.
C.The world’s economy will benefit from China’s policy changes on its currency.
D.The US will get hurt if it tries hard on damaging China’s economy.
小題2:This passage is in a tone that is ____________.
A.in favor of China
B.in the shoes of US
C.blaming China’s low currency policy
D.helping IMF solve the world’s economic problem
小題3:The writer makes his point of view clear through the passage by using _____________.
A.reasonable analysis
B.leaders’ quotations
C.figure examples
D.moving stories
小題4:China’s currency policy ________.
A.will help increase the demand in the US
B.is unable to equip the American labor force with new working skills
C.could guide the world economy for the next decade
D.is to be controlled by the international currency groups

D
People in Shanghai can quench their thirst with high quality water if the Shanghai Water Authority (SWA) is able to make good on its word. It has vowed to make the city’s water match its status as a world class city.
“The current tap water quality meets national standards, but, compared with that of the European Union and the United States, it still needs to be improved.” said the SWA’s director general, Hang Jiayi.
In other developed countries, water fountains can be found almost everywhere—people do not bother with bottled drinking water.
By 2020, the water of the Huangpu River will be treated to reduce the amount of organic waste in it. Major water works that draw water from the Huangpu will need more treatment facilities to improve the colour, texture, ammonia(氨)and nitrogen content before 2010.
These treatment facilities are expected to cost 4 billion yuan, something that could affect the price of water, according to Chen Yin, SWA’s deputy director general.
Chen said that replacing water pipes was also a key project. The city’s aged pipes are mostly to blame for the bad water quality.
The SWA has started the water facilities renovation(更新)work, including the more than 14,000 kilometres of indoor piping, 107,000 tanks on top of the buildings, and more than 6,000 underground facilities.
World Water Day came on March 22, and this year’s theme is “Water for the future”. Beijing is also drawing up plans during China’s Water Week, which runs until March 28.
By 2010, the water for the Shanghai EXPO is to be above World Health Organization standards. And, the people of Beijing will be able to drink their tap water as well.
小題1:People in Shanghai can drink their tap water_____.
A.by 2020B.in the first half of this yearC.by 2010D.by 2008
小題2:What step need not be taken in order to improve the tap water?
A.The water of the Huangpu River will be treated. B.Aged water pipes will be treated.
C.Water facilities must be renovated.D.Water fountains must be found.
小題3:Which is the correct statement according to the passage?
A.The tap water quality in Shanghai hasn’t met national standards.
B.World Water Day fell on March 22 this year.
C.The people of Beijing cannot drink their tap water now.
D.The treatment of the water of Huangpu River has been finished.
小題4:What is the main idea of the passage?
A.The cost of treating the tap water.
B.How to reach the water standards of developed countries.
C.The project for making tap water drinkable in Shanghai and Beijing.
D.The progress of treating the water of Huangpu River.

A new power plant in Nakoso, Japan, might someday change everything for coal plants.Since the new power plant fired up in September, the designer, Mistubishi, is expecting to prove it's possible to burn coal without polluting.This technology is known as integrated gasification combined cycle (IGCC).Proving IGCC works should give Mitsubishi's US partner, NRG Energy, the jump other hurdles to building new clean plants.
The project promised to solve the problem of the ages for power plants: how to produce cheap, clean, reliable electricity.No existing technology can do all three perfectly.
The problem is IGCC isn't there yet.It costs about 20 percent more than traditional plants.And even though it's easier to collect the resulting carbon dioxide from an IGCC plant than a traditional plant, there's no proven way to get rid of the greenhouse gas.One plan is to drill a shaft(通道) to pump the carbon dioxide underground, into saltwater formations.But there's no guarantee it will remain underground forever.
NRG administrators think solving the IGCC riddles is worth the trouble because they expect the U.S.will soon limit the amount of carbon dioxide that power generators may give out .
"With the additional cost of IGCC, to just voluntarily build something that's 20 percent more expensive, that’s commercial suicide," NRG chief administrator, David Crane said.
NRG administrators expect the cost to decline after six or seven plants are built.But other industry experts think it will take about a dozen plants for the price to be competitive with traditional coal plants.
Takaya Watanabe, a vice general manager of Mitsubishi, admits that the cost challenges are difficult.“It’s good for a company to say we want to be green, but unless someone is willing to pay, it's a dream.It won't keep our family eating rice," he said.
小題1:What is expected of the new technology?
A.To make electricity without polluting the air.
B.To produce energy without burning coal.
C.To keep the use of electricity cheaper.
D.To pump carbon dioxide more easily .
小題2:What's the biggest problem the companies are faced with?
A.How to pump greenhouse gases.
B.How to deal with the high cost.
C.How to get along with other partners.
D.How to improve the new technology.
小題3:What can be inferred from the passage?
A.New technologies are unacceptable to people.
B.It's unlikely to build more new power plants.
C.The companies are run on a tight budget.
D.Going green is easier said than done.
