Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek god Helios was said to drive the sun around the sky with his chariot（战车）. But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.
So what does all this mean? Well, quite simply, there is now a plane （or “chariot”） that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths（希腊神话）, Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.
This plane is called Solar Impulse （“太阳驱动”号）. It will fly across the US in May. This is very important for the future of the world.
So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals（化学制品）from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.
Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.
小题1:What does “chariot” really refer to in the last sentence of Paragraph 1?

A．The Earth.

B．The Greek god.

C．Solar Impulse.

D．Birds.

小题2:Which of the following is TRUE of Solar Impulse?

A．It can only fly at night.	B．It has already flown across the US.
C．It is powered by the sun.	D．It needs gas to work.

小题3:In the passage, what is mentioned as the cause of pollution in China?

A．Overpopulation.	B．Burning coal or gas.
C．Using solar energy.	D．Heavy traffic.

小题4:What does the writer mean by “That’s a pretty long flight”?

A．It takes a lot of time to get Solar Impulse going.

B．Solar Impulse moves very slowly.

C．Solar Impulse will be in use for a long time.

D．Solar Impulse has a long way to go to take the place of the sun.

小题5:The passage is most probably taken from___________.

A．a Greek myth

B．a science fiction

C．a story-book

D．a science magazine

小题1:C
小题2:C
小题3:B
小题4:C
小题5:D

I know what you’re thinking: pizza? 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 (跳过) breakfast, and they have a lot of different excuses for doing it. Some say they don’t have time. Others think they’re “saving” calories, 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（装填） with vegetables, and you just eat one small piece.
Breakfast 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 (吃得过多) later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of getting 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 get the fat-burning effects.
小题1:The word “leftovers” in Paragraph 1 probably means_______.

A．food left after a meal	B．things left undone
C．meals made of vegetables	D．pizza topped with fruit

小题2: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 losing weight.

D．Eating vegetables helps save energy.

小题3:According to the last paragraph, it is important to_______.

A．be careful about what you eat	B．eat calorie-controlled food
C．heat up food before eating it	D．eat something for breakfast

小题4:The text is written mainly for those_______.

A．who want to lose weight	B．who go to work early
C．who stay up late	D．who eat before sleep

BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity.
Of course, astronauts can still produce tears. But crying is much more difficult in space, according to The Atlantic(大西洋月刊) in January. Without gravity, tears don't flow(流动) down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go-they just stick(粘) to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes...They just kind of stay there."
Besides making your vision(视线)unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging(刺痛) like crazy," Feustel told his teammate during the walk.
Since gravity doesn't work in space, astronauts need some extra help to get rid of（除去） the tears. Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away. Another choice is to just wait-"When the tears get big enough they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic.
There are lots of small things-things like crying-that we are so used to on Earth. We usually take them for granted until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up（呕吐）everything in their stomach, according to the UK National Space Center.
Therefore, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."
小题1:From Paragraphs 2 and 3 , we can know that_______.

A．astronauts are unable to feel sad in space

B．astronauts produce fewer tears in space

C．tears produced in space flow down more slowly

D．tears produced in space don't flow downward

小题2:What effect do tears have on astronauts?

A．They cause physical pain.

B．They bring comfort to them.

C．They make their vision clearer.

D．They float around and cause trouble.

小题3:The underlined phrase "take them for granted" in paragraph 7 means _______.

A．find them important

B．consider them useless

C．need them during an emergency

D．fail to notice their presence(存在)

小题4:The second-to-last paragraph (paragraph 7) is mainly about_______.

A．suggestions of how astronauts can stay comfortable in space

B．other basic things that are difficult to do in space

C．why burping is impossible in space

D．things human can't do without gravity

Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.
Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
小题1:Who thinks that students won’t have to go to school?

A．Everyone.

B．The writer.

C．Some people.

D．The teachers.

小题2:What does “a new kind of school” mean in the passage?

A．A school with many new computers.	B．A school with many new students.
C．A school with many new teachers.	D．A school connected to the Internet.

小题3:What the writer thinks is that____________.

A．schools are still necessary	B．more schools should be built
C．there should be fewer schools	D．more computers are needed in schools

小题4:Why do people think learning can take place at home, at school, and in the office?

A．Because whole city is connected to the Internet.

B．Because everyone can go on the Internet.

C．Because getting online is very easy.

D．Because Scientists could give talks through the Internet.

小题5:What fact does the passage NOT provide?

A．Technology will change our way of learning.

B．If you are a student, you can set up websites to show new technology.

C．The schools provide computer labs for those who have no personal computers.

D．On the Internet, you can visit another city's libraries as easily as the people there.
