短文理解
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.

短文理解答案解析
農(nóng)民不喜歡烏鴉，因為這些鳥會吃掉新種下的種子。他們擔(dān)心如果烏鴉吃光了所有的種子，到秋天他們將一無所獲。農(nóng)民們很難接近烏鴉到足夠殺死它們的距離。烏鴉有非常好的視力和聽力并且非常謹(jǐn)慎小心。當(dāng)一部分烏鴉在吃新種下的種子時，其他的烏鴉就蹲在田地周圍最高的樹上。只要一看到農(nóng)民來了，烏鴉就會“呱呱呱”地叫起來。只要第一個叫了，其他望風(fēng)的烏鴉也會一起叫起來，馬上田地里就一只烏鴉也沒有了。
農(nóng)民們找到了一些殺死烏鴉的方法。但是有烏鴉存在還是有好處的。這些鳥兒是我們的朋友。它們會通過吃掉害蟲來彌補(bǔ)吃下的種子。比如，一只害蟲可以在幾個小時內(nèi)就吃光幾株植物，那么上千只害蟲一晚上吃下來，我們就沒東西可吃了。這就是為什么我們不應(yīng)該試圖殺光烏鴉的原因。
56.B【精析】句意：根據(jù)本文作者，烏鴉只會給農(nóng)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(nóng)民們要?dú)⑺罏貘f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(nóng)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(nóng)民它們吃掉的種子，但是沒有說農(nóng)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(xiàn)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。
