三、阅读理解。(每小题3分，共30分)
A
My name is Peter Green. I live in Australia. I had a very unusual experience. I saw a UFO in the daytime.
Early this spring, I went outside with my friend Barry who lived close to me. We were walking home when I saw a large round bright thing moving around in the sky. I called Barry and asked him to look up. He kept asking, “What's that？” It was round and red in the center.
I looked at it for a moment. It seemed that it had wings. Barry would not believe me when I told him it must be a UFO. We shouted to it excitedly and we wished that it would land. We wanted to know if there was an alien in it.
Seeing it was still in the sky, Barry said, “Camera! Camera！” He ran as quickly as possible to his home to get a camera. But when he returned, the UFO had already left.
Maybe our shouting scared it We were both regretful for not taking any photos of the UFO.
26. The story happened ____.
A．late in spring
B．at night
C．in Russia
D．during the daytime

C．an alien would visit them
D．an alien would shout to them
29. Barry ran home to ____.

B
Glaciers(冰川) are large bodies of ice and snow. Because they're so icy, it's very hard for things to live on them. But glacier mice do somehow.
Of course, glacier mice aren't real mice. They're round balls of moss(苔藓) that can grow to about the size of a tennis ball. They're usually found in groups near small rocks on the surface of icy glaciers.
Normal moss can't form on a glacier, so scientists believe glacier mice probably form around something small, like a bit of dust(尘土). Because staying on the ice too long would kill the moss, glacier mice form into a ball. It allows them to move around, so that their different parts touch the ice at different times.
Some scientists once did an experiment on glacier mice. They put a small device(装 置)inside 30 glacier mice to follow their movements. They learned that the mice traveled about 2.5 centimeters a day. They seemed to move in groups. They moved in the same direction and at about the same speed, almost like a group of animals. The scientists tested several ideas that might explain how the mice moved together, such as rolling downhill，being blown by the wind, or following the sun. None of these explained the movement of the glacier mice.
Glacier mice are still a mystery to scientists. For their next experiment, the scientists said they would use cameras to take pictures of the movements of the mice over a long period of time. Are you looking forward to the answer
31. Glacier mice can be as large as ____.
A．a basketball B．a tennis ball
C．a baseball D．a soccer ball
32. Why do glacier mice probably form into a ball
A．Because the moss is round.
B．Because they're on round rocks.
C．To keep a short time.
D．To keep cold away.
33. How far did the mice move a day in the experiment
A．About 3 cm.
B．About 2 cm.
C．About 3.5 cm.
D．About 2.5 cm.
34. Which of the following is TRUE
A．Nothing can live on glaciers.
B．Glacier mice move in different directions.
C．Glacier mice are a kind of moss.
D．Glacier mice aren't a mystery to us any longer.
35. Where can we probably find the passage
A．In a science magazine.
B．In a storybook.
C．In a history magazine.
D．In a science fiction novel.
四、任务型阅读。(每小题2分，共10分)
On the dark night of May 5 in the year 1110, the moon slowly disappeared. Though the stars and the sky could be clearly seen, the moon couldn't be seen until nearly daytime. People expressed their worries about it, but nobody knew what happened. For over 900 years, scientists have been trying to figure out what caused the strange event. However, hardly anybody was able to come up with any ideas.
Now scientists have finally found an answer—volcanoes(火山)！The forgotten eruptions(爆发)of Japan's Mount Asama happened around the beginning of September in 1108 and lasted nearly two months. A lot of ash(灰尘)was produced. It moved slowly towards the sky and finally covered the moon.
But how did scientists discover this They had to look at the ice from Greenland and Antarctica. The huge ice is useful to scientific study. It can show what the climate(气候) was like a long period of time ago and what was in the air at that time. Scientists noticed that there was more volcanic ash in the ice around May 5，1110.
Tree rings were also helpful in getting the answer. The rings change thickness with the climate. Scientists were able to see the year 1109 was a cold and rainy year and that people failed to get enough food. This supported the idea that a volcano had erupted.
