If you put a buzzard(秃鹰) in a cage without a roof(顶棚), the bird will be a prisoner. Even though it can fly, it can’t fly through the open roof. The reason is that a buzzard always begins a flight from the ground with a run of 3 or 4 meters. Without space to run, he will not even try to fly, but will stay in his small jail(监牢) for the rest of his life.
The ordinary bat that flies around at night cannot take off from the ground. If it is placed on the ground, all it can do is shuffle(穿梭) about helplessly. If it reaches a higher place, it will be able to throw itself into the air. Then it takes off quickly. But on flat ground, it will never fly.
A bee dropped into a cup will be there until it dies, unless it is taken out. It never sees the means of escape at the top, but keeps trying to find some way out through the sides near the bottom. It will look for away where none exists, until it completely destroys itself.
In many ways, there are lots of people like the buzzard, the bat and the bee. They are struggling with all their problems and frustrations(挫折)，not realizing that the answer is right there above them.
A buzzard can’t fly through the open roof of a cage because .

A．it is too big and heavy to fly up

B．it feels the space is too small to start the flight

C．it gets used to living in the cage without a roof

D．it would like to spend the rest of his life in the jail

Paragraph 2 mainly tells us that.

A．the bat is a kind of smart bird

B．the bat can take off quickly on flat ground

C．the bat flies only at night

D．the bat can only take off from a higher place

Which is NOT true about the bee?

A．The bee doesn’t try to find a way to escape.

B．The bee will die if it isn’t taken out of the cup in time.

C．The bee always wants to escape from the cup near the bottom.

D．The bee doesn’t see the way out at the top.

What’s the purpose of the story?

A．Many people are like the buzzard, the bat and the bee.

B．Animals will also give up when in trouble.

SPACE is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds.
We still know very little about space, and about living in zero gravity. In fact, we are discovering new things every time astronauts take to the skies (and beyond). As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries, gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry your tears have nowhere to go. As a result, they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this. “Tears,” as he said, “don’t fall off your eye… they just kind of stay there. ” This can be quite painful. In space, your eyes get very dry, and the added moisture is irritating (气人的). Sometimes, things get even weirder(更怪异的). The astronaut Ron Parise told The Atlantic that when tears get big enough, they “break free of the eye and float around”.
No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger.
The first paragraph mainly wants to tell us that .

A．living in space is lonely

B．it’s easy to feel sad in space

C．it’s hard to cry in space

D．nobody wants to live in space

If astronauts cry in spacecraft, their tears will .

A．move downwards	B．move upwards
C．go out of the window	D．stick to their eyes

Astronauts feelif tears are always in their eyes.

A．sad

B．comfortable

C．happy

D．uncomfortable

What can we learn from the passage?

A．In space our eyes are very wet.

B．Tears will float around if they are big enough in space.

C．People know everything about living in zero gravity.

D．Gravity makes people’s tears move upwards in space.

Long long ago, a king had a big rock placed in the middle of a very busy road. Then he hid nearby to see if anyone would move the rock out of the way to make it convenient for others. Some of the king’s wealthiest supporters came past and simply walked around it. Many others complained about the rock and some blamed the king for the problem. To the king’s surprise, no one did anything about moving it out of the way.
Finally, a poor farmer came along, carrying a load of old vegetables. When he saw the rock, he put down his load, and tried to move the heavy rock to the side of the road. No one stopped to help him. Many laughed at him and made jokes as they walked past. Finally, after much pushing and straining, and with no help , the farmer managed(设法) to get the rock to the side of the road. As he bent down to pick up his vegetables, he noticed a small bag lying in the road, exactly where the rock had been. There was a lot of money and a note in the bag. The note was from the king saying that the money was for the person who moved the rock out of the way.
Taking responsibility(责任) is about solving hard problems. The farmer takes responsibility when no one else is prepared to. It does not always mean that you will get an instant reward, but it is a value that builds up a community, and makes life better for all of us.
The word “convenient” in Paragraph1 meansin Chinese.

A．重要的

B．方便的

C．必要的

D．有用的

Why did the king put a big rock in the middle of the road?

D．To see how people walked around it.

Who moved the rock away？

A．The king	B．The king’s supporters.
C．The wealthy	D．A poor farmer

The story mainly tells us that.

A．everyone should learn to take responsibility

B．nobody likes to solve hard problems

C．taking responsibility always means getting a reward

D．the poor always take more responsibility than the rich

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered a planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）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（万亿）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 spacec raft 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 right 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（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether 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.
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.

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

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

Which of the following is the best title for the passage above?

A．Gliese 581g, a Likely Living Planet	B．Gliese 581, a Likely Living Planet
C．Gliese 581g and Its Star	D．Gliese 581g and Radiation

In 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist .So he invented a very simple camera. He put it in a window of his house and took a picture of his garden .That was the first photo.
The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room .He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.
Soon, other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world .people took picture of famous buildings, cities and mountains.
In about 1840, photography was improved .Then photographers could take pictures of people and moving things .That was not simple .The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people .The pictures were unusual because they were very lifelike.
