Some scientists say that animals in the ocean 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(分贝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.
Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which 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(感染的).
Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.The second paragraph mainly tells us that the noises on land and in water .
| A．are both from human activities. |
| B．both do harm to sea animals |
| C．are measured differently |
| D．have the same effect on humans |
As to(依据) the effects of noises on whales, which of the following statements is TRUE according to the passage?
| A．They are deaf to noises. |
| B．Noises at a certain level may hurt them. |
| C．They are easily confused by noises. |
| D．Noises will limit their ability to reproduce. |
Many researchers think that the noise limit of 120 decibels would .
| A．protect whales from noises |
| B．benefit them a lot in their research work |
| C．do good to their health |
| D．increase industrial output |
What will scientists most probably do in the future?
| A．Count the number of sea animals. |
| B．Stop their research on the ocean. |
| C．Study the effect of different noises. |
| D．Protect sea creatures from harmful noises. |
I know what you’re thinking : pizza （比萨饼）? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.I know lots of women who skip breakfast （不吃早餐） , and they have a ton of different excuses for doing it . Some say they don’t have time. others think they’re “saving” calories （卡路里）, still others just don’t like breakfast food .But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece. 21Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.The word “leftovers” in Paragraph 1 probably means__________.
| A．food remaining after a meal |
B．things left undone |
C．meals made of vegetables | D．pizza topped with fruit |
What can we infer from the text?
| A．Working women usually have breakfast in a hurry. |
B．Many people have wrong ideas about breakfast. |
C．There are some easy ways of cooking a meal. |
D．Eating vegetables helps save energy. |
According to the last paragraph, it is important to____________.
| A．eat something for breakfast | B．be careful about what you eat |
| C．heat up food before eating it | D．eat calorie-controlled food |
The text is written mainly for those_____________.

The year 2009 is the Year of Ox. The ox is a representative of the farming culture of China. In the farming economy （经济）, oxen are the major animals pulling plows （犁）.
Of course, the good of oxen is not limited to plowing. In fact, they are seen as "boats on land" for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who1ive in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar （农历）, and during their run they will take their oxen along, which indicates they regard the creature as human.Because of the contribution of oxen in their lives, the Chinese people are very grateful to the animal.

Brian arrived at the San Francisco airport two hours before the flight to Paris. He was wearing three shirts, a jacket, two pairs of socks, a pair of shorts, and two pairs of jeans. He was carrying one small backpack, which was very full, but he didn’t have any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a round-trip ticket and a small package.

Parties held by the wealthy seldom welcome poor guests.But last week China made it through the doors into a gathering of the world’s richest countries.
Jin Renqing ,Chian’s finance minister,and Zhou Xiaochuan,governor of the People’s Bank of China,joined a meeting of the Group of Seven(G7)on October1,2004.It is the fist time that China has had direct talks with the club.It was a good chance to share the world powers’thoughts about critical economic issues and promote understanding.
China’a participation is a natural part of its increasingly important role in the global economy.China is the world ‘s factory and the biggest market.
America and China made up almost half of global economic growth last year.“If Anerican consumers and Chinese producers were to reduce their activities at the same time,global growth would drop greatly,”said the Economist,a leading British economics magazine.
Up to now chinese economic stability(稳定)has been closely related to world development.“The increasingly connected global economy means that China should be a part of the meeting.”said Stephen Roach,a world famous economist.
During the meeting,China represented (代表)developing countries.It callde on the world’s developed nations to increase their spending on aid to poorer countries.Jin said that overall official help from developed countries is only 0.23 per cent of their Gross Domestic Product(国内生产值),much lower than the 0.7per cent UN targert.And this should be changed.According to the passage,China particpates in the meeting of G7 because______.
| A．China has become one of the richest countries of the world |
| B．China is playing a more important part in the world economy |
| C．China has more factories than any other countries in the world |
| D．developing countries want China to speak for them |
