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 counting on to satisfy their energy needs according to the passage?

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.
What a Scientist Is Like
If you were asked to imagine a scientist,what image（形象）would come to your mind?The common idea that most kids from kindergarten through college have of a scientist is a man wearing a white lab coat with messy hair, big glasses,and several glass cups of mysterious colorful liquids giving off clouds of smoke.As for adults,the majority view scientists as strange people who spend 100 hours a week slaving away in a lonely laboratory.However, the reality is quite different.
Recently I’ve had a chance to take part in a scientific experience far from my laboratory and into Costa Rica.It supports a huge amount of wildlife due to its geographical placement between North and South America.It is home to more than 500,000 species,which represents nearly 4% of the total species worldwide!
First we worked alongside conservationists to preserve wildlife at a leatherback turtle（棱皮龟）rescue center. We helped the volunteers preserve turtle populations by removing rubbish from the shoreline to create a safe environment for turtle eggs to come out.After that we stayed at Mount Arenal where we studied seismic activity relating to earthquakes.During our stay at Arenal,we rode over the mountainous areas and took a long walk through the rainforest.After reaching the top,we went down and through waterfalls to the beautiful valley below!On the last day we got a hands-on introduction to rocket science where we learned about new rocket technology that will be used on the international space station.
During my Costa Rica experience,I know that being a scientist doesn’t mean working in a lab all day and night. A scientist is one who loves learning and getting a better understanding of the world from helping preserve wild-life, learning about earthquakes or inventing rockets.I think that schools should really stress that science is so much more than wearing a lab coat and mixing chemicals.Kids need to be aware of the excitement and adventures science can bring!

An artist in Bogota, Colombia is using his skills to aid the homeless. Greg Kloehn builds very small shelters that make life on the streets a little more comfortable. The structures offer the homeless some safety and protection from bad weather. Each little house also has wheels on the bottom so it can go wherever its owner goes.
Greg Kloehn has given away at least 20 tiny houses. Several are on the roadside near an active railroad. On a recent day, Mr. Kloehn stops at one to visit Oscar Young. The two men hug. Inside his little shelter Mr. Young gets relief from cold nights on the streets. Mr. Kloehn also visits Sweet-Pea, another friend who also lives in one of the little homes the artist built. She says it keeps her safe and protects her belongings.
In the mornings, Mr. Kloehn searches the streets for building materials. He gathers what he can and takes it to his studio. There, he puts the houses together. Empty coffee bags become roof material. A washing machine door and refrigerator part become windows. Nails, screws and the sticky glue hold all the pieces together. The artist also attaches a small electrical device to the house. The device is powered by the sun.
Some of the people living on the streets once had normal houses of their own. But some of the people say they have learned to live with less and they are thankful to that man.
Mr. Kloehn says his work is not a social project. He says he is just someone applying his skills to helping his homeless neighbors.
