　　第三部分阅读理解

　　短文理解1

　　阅读下面短文，从A.(Right)、B.(Wrong)、C.(Doesn’t say)三个判断中选择一个正确选项，并在答题卡上将该项涂黑。

　　Farmers do not like crows (乌鸦) because these birds eat newly-planted seeds (种子). They are afraid that they will not have anything left in autumn if the birds eat up all the seeds.

　　It is hard for farmers to get close enough to kill crows. Crows have very good eyes and good hearing. They are also very careful. While some are eating the newly-planted seeds, others sit on the tallest trees around the fields. "Caw-caw-caw," cries the first crow to see farmers coming. All the other "lookout" crows join in the crying and then, in no time at all, there is not a crow to be seen. Farmers have found several ways to kill crows. But it is good that there are still crows about. These birds are our friends. They pay for the seeds they eat by killing pests(害虫). One pest, for example, can eat up several plants in a few hours. With thousands of them at work in one night, we might find ourselves without food to eat. This is why we should not try to kill off the crow.

　　56. According to the writer, crows only bring troubles to farmers.

　　A. Right

　　B. Wrong

　　C. Doesn't say

　　57. It is not easy for farmers to kill crows.

　　A. Right

　　B. Wrong

　　C. Doesn't say

　　58. Farmers can get paid by killing pests.

　　A. Right

　　B. Wrong

　　C. Doesn't say

　　59. Up to now, no ways have been found to kill crows.

　　A. Right

　　B. Wrong

　　C. Doesn't say

　　60. Crows eat seeds and pests at night.

　　A. Right

　　B. Wrong

　　C. Doesn't say

　　答案解析：

　　56.B【精析】句意：根据本文作者，乌鸦只会给农民带来麻烦。是非题。从文章第三段第二句“But it is good that there are still CROWS about.”可以推断出，本题的判断是与原文不符。故选B。

　　57.A【精析】句意：农民们要杀死乌鸦并不容易。推断题。从文章第二段前三句“It is hard for farmers to get close enough to kill crows.Crows have very good eyes and good hearing.They are alsovery careful.”可以推断出本题是正确的。故选A。

　　58.C【精析】句意：农民们杀死害虫会获得报酬。是非题。文章第三段只是说乌鸦会通过杀死害虫来回报给农民它们吃掉的种子，但是没有说农民杀死害虫会获得报酬。题干说法文中并未提及，故选C。

　　59.B【精析】句意：直到现在，人们还没有找到杀死乌鸦的方法。是非题。文章第三段第一句“Farmers have found several ways to killcrows.”可以推断出，本题的判断与原文不符。故选B。

　　60.C【精析】句意：乌鸦晚上吃种子和害虫。推断题。从文章第一段和第三段我们知道乌鸦会吃种子和害虫，但是并没有指明是在晚上。故选C。

　　The train arrived early. Mara didn't know the station very well and instead of going to the west entrance, she went out of the north entrance and waited for Fanny there.

　　Fanny checked at the information desk and found that the train had already arrived. She looked round near the west entrance of the station but couldn't see Mara anywhere. She began to think that Mara must have missed the train.

　　Mara waited at the north entrance, but she couldn't see Fanny. She decided that Fanny was not coming to meet her after all. So she walked across the road to the bus station and asked for the bus to Market Road, where Fanny lived.

　　You can imagine(想象 ) how surprised Fanny was when she arrived home and found Mara al-ready talking to her mother.

　　61. When did Mara tell Fanny about her train ride?

　　答案解析：

　　61.B【精析】句意：玛拉是什么时候告诉范妮她乘坐的火车的?细节题。从文章第一段第二句“A week before her trip，she called Fan—ny to tell her when the train would arrive.”可以得出，玛拉是在旅行之前一周告诉范妮火车何时到达的。故选B。

　　62.B【精析】句意：为什么玛拉去了北进站口而不是西进站口?细节题。从文章第二段第二句“Mara didIl’t know the station verywell…”可以看出，玛拉是由于不了解火车站而走错的，故选B。

　　63.A【精析】句意：玛拉没有在火车站等范妮是因为——。细节题。从文章第四段第二句“She decided that Fanny was notcoming to meet her after all.”可以看出，玛拉没有在火车站等范妮是因为她觉得范妮不会来接她了，故选A。

　　64.C【精析】句意：在下火车后玛拉是如何到达Market路的?推断题。从文章第四段最后一句“So she walked across the road to the busstation and asked for the bus to Market Road，where Fanny lived"可知，玛拉去马路对面的公交车站问了到范妮家街道的公交车。因此，可以推断出玛拉是坐公交车到范妮家的。故选C。

　　短文理解3

　　today we are sure that the mail will be sent every day to our door. But in the early days, no one could be sure about where--or when--the mail would arrive.

　　There is a stump (树桩) of a big tree in the state of Washington. It was once a "post office". Because people needed a place for the mail carrier(信使) to leave their letters, they found a tree at the cross of roads and cut it down ten feet from the ground. Then they hollowed it out and covered it with something. Inside, they put many boxes. Each box had a family's name on it. The mail carrier could leave letters there for everyone.

　　Even earlier, when there was no post services, people gave their letters to any traveler going in the right direction. Often they gave them to a traveling shoe maker. The traveler might stop in a small hotel and he would leave the letters there. But the letters stayed there until the person to re- ceive them happened to come by and stop at the hotel.today an airmail letter can travel across the world in much less time than that. And you know that your letter will go where you want it to go, and when.

　　66. What is the text about?

　　A. The uses of a mail box.

　　B. The early days of the mail.

　　C. The post service in Washington State.

　　67. Why did people cut down the tree?

　　A. to make it into a "post office".

　　B. to use it for building houses.

　　C. to build mail boxes.

　　68. What does "hollowed it out" mean in "Then they hollowed it out..."?

　　A. Made its inside empty.

　　B. Covered its stump up.

　　C. Cut it short.

　　69. Who often worked as a mail cartier when there was no post service?

　　A. A hotel owner.

　　B. A letter writer.

　　C. A shoe maker.

　　70. What do we know about the post service in the old days?

　　A. Hotels offered post service.

　　B. Letters were sent to the door.

　　C. When letters would arrive was not clear.

　　答案解析：

　　66.B【精析】句意：这篇文章是关于什么的?主旨题。文章除首末段引入和结语外，主体的`二、三两段都是关于早期邮递服务的，可以推断出，这篇文章是关于早期信件邮递的，故选B。

　　67.A【精析】句意：为什么人们会砍断那棵树?细节题。从文章第二段第二句“It Was once a‘post office’.”可知，人们砍断这棵树把它做成了一个“邮局”。故选A。

　　68.A【精析】句意：在“Then they hollowed it out…”这句话中“hollowedit out”是什么意思?词汇题。“hollowed it out”是挖空的意思，B项意为将树桩盖起来，C意为把它砍短。故选A。

　　69.C【精析】句意：在还没有邮政服务的时候是什么人充当信使的?细节题。从文章第三段第二句“0ften they gave them to a trave—ling shoe maker.”可以看出，人们会把信件托付给四处旅行做生意的鞋匠。故选C。

　　70.C【精析】句意：关于古代的邮政服务，我们了解了哪些?推理题。从文章第一段第二句“But in the early days，no one could be sureabout where—or when一the mail would arrive.”可推出C项符合。而文章第三段虽提到旅行者会将信件存放在旅馆直到收信人碰巧路过取走，但是并没有说旅馆提供邮政服务，故A项不符合文意;B项信件会被送到门口也在文中无法证实。故选c。
