Do you think alien beings exist somewhere in the universe? It seems like Mars, our closest neighbor, has inspired the most science fiction as the place where aliens are most likely to come from. Recent Mars probes (探测) have shown us that there is no life on that planet—at least not now. But that does not mean that life does not exist elsewhere—after all, the universe is really big. A lot of scientific research is going on in the search for “extraterrestrial life”.
Think about it—why should the seven billion people on this little planet be the only living beings in the universe? It would, in fact, seem logical that this is not the case. So scientific research in this matter is based around the idea of finding other planets that have environments that can support life —environments similar to the Earth. The search is on for the evidence of the existence, or earlier existence of life: from very wise beings to simple organisms (有机物).
So far, there have been a number of theories as to which planetary bodies may have an atmosphere that can support such life and therefore deserve closer attention. As for places within our own Milky Way Galaxy, it has been assumed over the decades that Mars and Venus, as well as some of the moons of Jupiter and Saturn, may have been hosts for life. Now, as technologies have improved and we can obtain measurements of the composition of the atmosphere on extra-solar planets, the chances of finding “alien” life forms are increasing.
There has been a theory that some of the planets in the habitable zone of the red dwarf star Gliese 581 may be able to support life. In 2007, scientists discovered exoplanet Gliese 581c—and felt that its atmosphere was most suitable for supporting life. But further research revealed that it would not. Now, attention has been turned to Gliese 581d, at the outer edge of the star’s habitable zone. The main standards for deciding whether a planetary body can be life-supporting are atmospheric conditions which allow the existence of water. Gliese 581 is about 20. 4 light years away from the Earth, so even if life does exist there, the distance would mean that communication would be unlikely.
Having said this—who says alien life forms (if they exist) need water?
1.What does the underlined part in Paragraph 1 mean?
A.Life existing outside of the Earth.
B.The evidence of the existence of life.
C.Other faraway planets in the universe.

A.the atmosphere of Gliese 581c was most suitable for life
B.it is not certain whether alien life forms need water or not
C.the 7 billion people on the Earth are the only beings in the universe
D.the distance of 20. 4 light years makes it impossible to find life on Gliese 581d
4.Which of the following is the best title for the passage?
A.Do Aliens Exist? B.Is Mars Suitable for Life?
C.Are Alien Life Forms Various? D.Can We Communicate with Aliens?
Dear Sir,
I am writing in reply to your article about homelessness in Ledchester as it raises questions about whether or how we should give money to charity.
There are now so many chances to give to charity in the UK these days that it can be difficult to know what is best to do. As your article said, if you go shopping in Ledchester city centre, there will be many chances to give money to charity, or to homeless people who look poor, tired and cold, but the solution is not as easy as you seem to think. Can I be sure that the person won’t spend the money on alcohol(酒) or drugs? You seem to have forgotten the research which showed that 9 out of 10 people begging on the street spend the money they are given on alcohol and drugs. Also, can I be sure that the person isn’t one of those “professional beggars” who simply pretend to be homeless and poor?
I think a more effective way to give money is to buy things in one of the many charity shops in Ledchester such as the Oxfam shop. This isn’t really charity as you are buying something, but you know the money is going to a good cause.
In recent years, as we all know, there have been a lot of big events organized to raise money for charity. Many will remember “Live Aid”. Lots of famous bands got together to hold a concert and make a record with all the money going to Ethiopia because of the food shortages there. The BBC also has a “Children in Need” day every year. In one sense you could say that these events are very successful as they raise a lot of money. However, I don’t believe that these events solve the real problems. In my view, these events just allow people to feel good about themselves for a day and then forget about charity and problems in the developing world for the rest of the year. My wife and I decided to support a child. We give a certain amount of money every month and this goes to pay for the education of a girl in Ethiopia. I would encourage your readers to support a child too. We don’t know if it is the best way to help, but at least it is something.
Yours faithfully,
Tom Blinson

It was Monday morning, and the writing class had just begin. Everyone was silent, wait to see who would be called upon to read his and her paragraph aloud. Some of us were confident and eager take part in the class activity, others were nervous and anxious. I had done myself homework but I was shy. I was afraid that to speak in front of a larger group of people. At that moment, I remembered that my father once said, "The classroom is a place for learning and that include learning from textbooks, and mistake as well." Immediate, I raised my hand.
