With environmentalists pointing to the use of coal, oil and other fossil fuels as adding to the problem of global warming, the world is rushing to find other more environmentally friendly energy sources. Many countries are looking to nuclear power as the answer to their energy needs. Those who support using nuclear power point to the fact that the process for creating nuclear power produces huge quantities of electricity without producing any greenhouse gases. It seems to be the safest and most environmentally safe method for producing the largest amount of power, much more than solar or wind energy sources.

However, despite the many advantages of nuclear power, there are many groups who strongly advise against the use of nuclear power. Some groups point to concerns about possible terrorist attacks on nuclear plants or possible nuclear accidents that might result in widespread disaster. However, strange as it seems, many of the strongest voices against nuclear power are actually environmentalists, who oppose nuclear power because they claim it results in more greenhouse gases.

It may seem impossible, but in fact both facts are true: nuclear production itself produces no greenhouse gases, but nuclear power does, in fact, lead to the production of many greenhouse gases. How is this possible? The actual production of nuclear power does not let off any greenhouse gases at all; this is the fact that most governments and nuclear power companies point to, and it is, indeed, correct. However, those who oppose nuclear power point out the bigger problem: building and maintaining the nuclear power stations, mining the material used to produce the nuclear power and getting rid of the nuclear waste all create greenhouse gases, the very thing that nuclear power is supposed to avoid. The final point that environmentalists point out is that nuclear power is not a long-term solution to energy. One day uranium, the resource needed for producing nuclear power, will be at an end, the same problem the world is facing with coal and oil today.

1.What are many countries relying on to satisfy their energy needs according to the passage?

A. Coal. B. Oil.

C. Nuclear power. D. Other fossil fuels.

2.What disadvantages relating to the use of nuclear power are mentioned in the passage?

A. No greenhouse gases.

B. Killing more plants.

C. Widespread disasters and more greenhouse gases.

D. Making other energy sources not function well.

3.What’s the writer’s attitude towards the use of nuclear power?

A. Optimistic. B. Indifferent(漠不关心).

C. Pessimistic. D. Objective(客观的).

4.Why do some environmentalists point out that nuclear power is not a long term solution to energy?

A. Because the resource for producing nuclear power will come to an end someday.

B. Because they think nuclear power gives off too many greenhouse gases.

C. Because the world is facing coal and oil shortages now.

D. Because more and more people are opposed to the use of nuclear power.

When I was about 10, I was walking down the street with my mother. She stopped to speak to Mr Lee. I knew I could see Mr Lee anytime around the neighborhood, so I just stood there. After we passed him, my mother stopped and said something unforgettable, "You let that be the last time you ever walk by somebody you know without opening your mouth to speak, because even a dog can wag its tail when it passes you on the street." That sentence sounds simple but it made me become who I am.

At work, I used to say hello to the president of the company and ask him how our business was doing. But I also spoke to the people in the cafe? and people who cleaned the buildings, and asked them how their children were doing, for every single person deserves to be accepted, no mater how humble (卑微的)they are. I remember that after a few years of passing by the president, I had the courage to ask him for a chat. We had a great talk. At some point, when I asked him how far he thought I could go in his company, he said that if I wanted to, I could get all the way to his seat.

I've become vice president, but that hasn't changed how I treat people. I speak to people wherever I am. Speaking to people creates a pathway into their world, and it lets them come into mine, too. The day you speak to someone who has his head down and then see him lift it up and smile, you will realize how powerful it is just to open your mouth and say hello.

1.What is the best title of this passage?

A. The Power of Being Talkative

B. My Mother's Influence on Me

C. The Power of Saying Hello

D. My Way to Become Vice-president

As we all know ,trees are important to our life. They provide us with food, wood and most importantly, oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria in water.

The discovery was made by some scientists and high school students who were seeking for a natural water filter(过滤器)—one that could help people in developing countries that don’t have access to modern water systems.

The researchers, led by Rohit Karnik, a professor ,decided to turn to trees for help because they were able to allow liquid to flow through while blocking out air bubbles(气泡).

They began by cutting 1.5-inch-wide sections of tree bark from the branch of a white pine tree. The researchers then tested the wood’s filtering ability by pouring water containing red dye particles(染料颗粒)of different sizes through. To their surprise, they found it was effective in trapping all the particles. Encouraged, the team did another experiment, this time with water containing bacteria. Sure enough, the bark held back 99%of the bacteria, allowing only 1% to flow through.

Mr. Karnik said the bark was able to filter water containing much smaller particles. This means that it can be used to get rid of most of the bacteria. However, what troubles them is that tree bark cannot hold back viruses, which tend to be much smaller.

Though the experiment is successful, we must remember one thing—the bark only works when damp. This means that before this natural filter can be put to practical use, the researchers will have to figure out how to keep the bark damp, or find a way to keep the bark’s great filtering ability even when it’s dry.

But the study is not done. The researchers plan on testing other types of trees, including those flowering trees. They think those may be more effective in trapping smaller particles and even viruses.

1.How will the discovery affect the world?

A. No harmful bacteria will be found in water.

B. There will be no water pollution around the world.

C. More pine trees will be planted around the world.

D. Clean water will be more accessible in developing countries.

2.What problem troubles the researchers when using the trees bark as a water filter?

A. Viruses cannot be prevented.

B. Tree bark should be wet.

C. It’s hard to remove air bubbles.

D. Not all bacteria can be held back.

3.Why does the team plan to do other experiments?

A. To find other natural water filters.

B. To improve the filtering ability of other trees.

C. To find a way to keep the bark wet.

D. To test the filtering ability of other trees.

4.In which column of a newspaper can we read this text?

A. Culture. B. Science.

C. Lifestyle. D. Society.

Organic exercise is a good fit for people looking to train functionally. It is defined as exercise that is similar to the type of physical activity performed by ancient hunter-gatherer ancestors. Organic exercise is generally preformed in natural or outdoor settings. 1.Organic exercise may include such activities as walking, jogging, swimming, hiking or rock climbing.

When it comes to organic exercise, one of its most significant benefits is its limited reliance on equipment. 2.Going for a jog, walking, or even hiking does not require tools, weights, or even hiking does not require tools, weights, or other products, and therefore, is fairly inexpensive.

Since the types of activity emphasized in organic exercise programs are similar to those performed as part of daily life, they do not require extensive or long amounts of practice to obtain proficiency(精通). 3.Therefore the type of activity recommended in an organic workout routine can be performed by beginning or advanced exercisers alike with relative ease.

While the type of exercise recommended in an organic workout may be easy enough to perform, the intensity at which it is recommended can be too much for some individuals. 4.Individuals who are new to exercise or suffer from a chronic health condition that limits their physical ability may find it difficult to perform exercise that is especially strenuous.

5.Individuals who are new to exercise may want to talk with their health care provider before choosing this type of activity. In some cases, it may be better to start off with a more traditional workout and slowly transition to organic exercise than starting with this regimen(养生法)right off the bat.

A. Weigh both the benefits and drawbacks.

B. In fact, it can be done nearly anywhere, any time.

C. Therefore it requires very little helping equipment.

D. Choosing the right types of organic exercise is important.

E. Most adults already know how to hike, swim or dig, for example.

F. In fact, one of the biggest drawbacks is the emphasis on high-intensity exercise.

G. While organic exercise may be a good choice for some, it is right for all adults.
