     After spending years searching for a planet with life, scientists may have found one. In September 2010,
a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature
neither too hot nor too cold for liquid (液態(tài)) water. Scientists think there is a chance that the planet could
have life.
     The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth.
That is about 194 trillion (萬億) kilometres－500 million times farther away from us than the moon.
     A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years.
A human can't live that long, but robotic explorers could make the job easier. However, our fastest spacecraft
don't come anywhere near that one-tenth light-speed mark.
     At present, scientists don't know what the surface might be like on Gliese 581g. What they know is that
the planet is at the sight distance from its star to have liquid water. It's also at the right distance to have an
atmosphere that could protect the water if it is on the surface.
     Although spacecraft won't be getting there anytime soon, one way to look for life on Gliese 581g is to
turn our radio telescopes (望遠(yuǎn)鏡) towards the planet and search for radiation (放射). By studying the
radiation, scientists would find out about the chemicals (化學(xué)物質(zhì)) around the planet and discover it Gliese
581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has
life or not. But it'll probably be many years before we can do this properly.
     People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life
is just guessing at this point, according to its discoverers.
1. What did scientists find in September 2010?
A. A planet with water.
B. A planet similar to the earth.
C. A planet without life.
D. A planet near the earth.
2. According to the article, Gliese 581g ________.
A. is at the right distance from its star
B. moves around the earth
C. is as far away from us as the moon
D. can be reached in about 220 years
3. Paragraph 5 is mainly about ________.
A. the possibility of living on Gliese 581g
B. the kinds of chemicals around Gliese 581g
C. the way of looking for life on Gliese 581g
D. the aim of studying the radiation on Gliese 581g
4. Which of the following is the best title for the passage above?
A. Gliese 581g, a Likely Living Planet.
B. Gliese 581g, a Likely Living Planet.
C. Gliese 581g and Its Star.
D. Gliese 581g and Radiation.

      The customs in different countries are rather different. If I have dinner with a Chinese host, he always
puts more food onto my plates as soon as I have emptied it. That often discomforts me greatly. I have to eat
the food even if I don't want to, because it is considered (認(rèn)為) bad manners in the West to leave one's food
on the plate. I have already noticed that when a Chinese sits at an American's dinner party, he very often
refuses (拒絕) the offer of food or drink though he is in fact still hungry or thirsty. This might be good
manners in China, but it is not in the West at all. In the United States, it is impolite to keep asking someone
again and again or insist on his accepting something. Americans have a direct (直接的) way of speaking. If
they want something, they will ask for it. If not, they will say, "No, thanks." When an American
dislikes the beer served by the host, for example, he might say, "No, thanks. I'll take some diet Coca-Cola
(可口可樂) if you have it." That is what an American will do. So when you go to the United States, you
had better remember the famous saying: When in Rome, do as the Romans do.
1. From the passage, we can know that the Chinese are usually _______ to the guests.

4. When an American wants something to eat or drink at a dinner, he will _______.
[     ]
A. ask for it through others
B. refuse the offer
C. ask for it directly
D. express himself indirectly (間接地)
5. "When in Rome, do as the Romans do" means "_______".
[     ]
A. When you got to Rome, you should act as the Romans do
