三、阅读理解

Tommy got up very early on the Christmas morning.He looked in every room and wished a Merry Christmas to his family.Then he ran into the street to repeat that to those he might meet.When he returned to his home，his mother gave him two bright，new silver dollars.

His face lighted up as he got them.He had wished for 3 weeks to buy some pretty books that he had seen at the bookstore.He left his home with a light heart，and expected to buy the books.He was running down the street when he saw a poor family.

“I wish you a Merry Christmas.” said Tommy，as he was passing on.The man shook his head.“You are not from this country，” said Tommy.The man again shook his head，for he could not understand or speak his language.He pointed to his mouth and to the children shaking with cold，as if to say，“These little ones have had nothing to eat for a few days.” Tommy understood at once that these poor people were very hungry.He took out his dollars and gave one to the man，and the other to his wife.

They were excited and said something in their language，which doubtless meant，“thank you so much that we will remember you all the time.”

When Tommy came home，his mother asked what books he bought.He hung his head a moment，but he quickly looked up.“I have bought no books，” said he，“instead I gave my money to some poor people，who seemed to be very hungry then.” He went on，“I think I can wait for my books till next Christmas Day.”

“Oh，my dear boy，” said his mother，“here are some books for you，more as a prize for your goodness of heart than as a Christmas gift.”

“I saw you give the money cheerfully to the poor German family.It was nice of you，a little boy，to do so.Be always ready to help others and every Christmas of your life will become to you a Merry Christmas.”

Dust storms don't just happen in the middle of the desert.They happen in any dry area where loose dirt can easily be picked up.The sand blown into the air by the wind usually falls back down to the ground after a few hours.Smaller bits of particles (微粒) stay in the air for a week or longer and can be blown thousands of miles away.Dust from the Sahara is always blown across the Atlantic and keeps travelling as far as Caribbean.

The scary thing about sandstorm is that they can spread over hundreds of miles and rise over 10，000 feet (3050 meters). They also have wind speeds of at least 25 miles per hour (40km). Not strong enough to blow the feathers off a chicken but still something worth avoiding.

Don't be surprised if you suddenly see a dust storm heading your way.Dust storms usually arrive without warning and move in the form of a big wall of dust.The dust makes driving impossible.Often they only last for a few minutes but storms usually leave serious car accidents behind.If you are in a car during a dust storm，remind the driver to pull over and turn off the headlights.

In mild (轻微的) dust storms，it's still impossible to walk around although you wouldn't want to.You can't see anything because of the dust particles flying around.It's not just the dust you want to avoid.The wind carrying the dust will leave things as if they were just hit by a tornado.The best thing to do is find a safe place in a building.

5. What can we know from Paragraph 1?

A. Sand blown into the air can float for months.   

B. Dust storms don't happen in the heart of the desert.

C. Dust blown into the air can travel a very long distance. 

D. Smaller bits of particles stay in the air for only a few hours

6. What does Paragraph 2 mainly talk about?

A. The speed of the wind.     B. The harm of dust storms.

C. The movement of dust.     D. The power of dust storms.

7. What should a driver do when he is caught in a dust storm?

A. Stop by the roadside.     B. Slow down a little bit.

C. Turn on the headlights.     D. Drive along the side of the road.

8. Which of the following statement is TRUE when the dust storm is not strong?

A. You should find a safe shelter.   B. You can walk around as usual.

C. There is no need to avoid dust.   D. People can see everything clearly.

答案

三、阅读理解

1.C　细节理解题。根据第二段中“He left his home with a light heart，and expected to buy the books.”可知，汤米希望从他母亲那里得到钱后能买一些漂亮的书。故选C项。

2.A　细节理解题。根据第三段中“The man again shook his head，for he could not understand or speak his language.”可知，汤米跟这个可怜的人说话时他摇头是因为他不明白这个男孩的意思。故选A项。

3.B　推理判断题。根据最后一段中“Be always ready to help others and every Christmas of your life will become to you a Merry Christmas.”可知，作者试图鼓励我们随时准备帮助别人。故选B项。
