第三部分 閱讀理解
短文理解1
閱讀下面短文，從A.(Right)、B.(Wrong)、C.(Doesn’t say)三個判斷中選擇一個正確選項，并在答題卡上將該項涂黑。
Farmers do not like crows (烏鴉) because these birds eat newly-planted seeds (種子). 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(害蟲). 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：根據本文作者，烏鴉只會給農民帶來麻煩。是非題。從文章第三段第二句“But it is good that there are still CROWS about.”可以推斷出，本題的判斷是與原文不符。故選B。
57.A【精析】句意：農民們要殺死烏鴉并不容易。推斷題。從文章第二段前三句“It is hard for farmers to get close enough to kill crows.Crows have very good eyes and good hearing.They are alsovery careful.”可以推斷出本題是正確的。故選A。
58.C【精析】句意：農民們殺死害蟲會獲得報酬。是非題。文章第三段只是說烏鴉會通過殺死害蟲來回報給農民它們吃掉的種子，但是沒有說農民殺死害蟲會獲得報酬。題干說法文中并未提及，故選C。
59.B【精析】句意：直到現在，人們還沒有找到殺死烏鴉的方法。是非題。文章第三段第一句“Farmers have found several ways to killcrows.”可以推斷出，本題的判斷與原文不符。故選B。
60.C【精析】句意：烏鴉晚上吃種子和害蟲。推斷題。從文章第一段和第三段我們知道烏鴉會吃種子和害蟲，但是并沒有指明是在晚上。故選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.

64.C【精析】句意：在下火車后瑪拉是如何到達Market路的?推斷題。從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，瑪拉去馬路對面的公交車站問了到范妮家街道的公交車。因此，可以推斷出瑪拉是坐公交車到范妮家的。故選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 (樹樁) 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：這篇文章是關于什么的?主旨題。文章除首末段引入和結語外，主體的'二、三兩段都是關于早期郵遞服務的，可以推斷出，這篇文章是關于早期信件郵遞的，故選B。
67.A【精析】句意：為什么人們會砍斷那棵樹?細節題。從文章第二段第二句“It Was once a‘post office’.”可知，人們砍斷這棵樹把它做成了一個“郵局”。故選A。
68.A【精析】句意：在“Then they hollowed it out…”這句話中“hollowedit out”是什么意思?詞匯題。“hollowed it out”是挖空的意思，B項意為將樹樁蓋起來，C意為把它砍短。故選A。
69.C【精析】句意：在還沒有郵政服務的時候是什么人充當信使的?細節題。從文章第三段第二句“0ften they gave them to a trave—ling shoe maker.”可以看出，人們會把信件托付給四處旅行做生意的鞋匠。故選C。
70.C【精析】句意：關于古代的郵政服務，我們了解了哪些?推理題。從文章第一段第二句“But in the early days，no one could be sureabout where—or when一the mail would arrive.”可推出C項符合。而文章第三段雖提到旅行者會將信件存放在旅館直到收信人碰巧路過取走，但是并沒有說旅館提供郵政服務，故A項不符合文意;B項信件會被送到門口也在文中無法證實。故選c。
