Unit 24 The science of farming
例1 On Saturday afternoon, Mr Green went to the market, _________ some bananas and visited her cousin.
A. bought B. buying C. to buy D. buy
分析
本题考查的是并列的谓语与非谓语动词作状语的区别。英语中当几个动作以先后的顺序依次发生时,用并列的谓语动词表示。当几个动同之间有修饰的关系时,用非谓语动词作状语。
所以从题中and 表示并列的关系来看,也可直接得出brought与visited是并列谓语。答案为A。
例2 Mr Zhang gave the text books to all the pupils except _________who had already taken them.
A. the ones B. ones C. some D. the others
分析
the ones 等于the pupils,为了避免重复,用代词来代替。由于后有定语从句对先行词的限定,则先行词一般需加定冠词。the others在词义上与except重复,不可用。答案应为A。
例3 He asked _________for the violin.
A. did I pay much B. I paid how much
C. how much did I pay D. how much I paid
分析
本题考查的是疑问句变为间接引语后,宾语从句的语序及引导从句的连接词。在宾语从句中,需使用主谓语序,而不是疑问句中的倒装语序。本题只要掌握了宾语从句的一般要求,则不难得出正确答案为D项。
例4 In spring, the soil is _____ before seeds are sown.
A. turned on B. turned off C. turned over D. turned up
分析
此题考查动词turn的相关词组的意义区别。turn on意为“打开(电器、水龙头、煤气等)”;turn off意为“关掉”;turn over意为“翻转;使翻转”;turn up意为“把……量开大”或“出现”。本题题意为“春天播放前要翻耕土壤”。此题答案为C项。
例5 We all write______, even when there’s not much to say.
A. now and then B. by and by C. step by step D. more or less
分析
此题旨在考查短语意义区别。now and then意为“时而,不时”;by and by意为“渐渐地”;step by step意为“逐步地”;more or less意为“或多或少”,表示行为的量或限定一个量。此题中much表示行为的量,所以该用now and then来说明write的频度。此题答案为A项。
例6 They agreed ______ her, but so far she hasn’t turned up yet.
A. to meet B. meeting C. have met D. to have met
分析
agree后直接加不定式作宾语,表示“同意于某事”。如果强调一个动作发生在主句谓语动作之前,才能用不定式的完成式。据题意所知,D项不符。正确答案是A。
例7 —Is this raincoat yours?
—No, mine ______ there behind the door.
A. is hanging B. has hung C-is hanged D .hung
分析
hang表示“挂”的意思,作及物或不及物动词均可;若只表示所挂物品的状态时,常用作不及物动词,直接用进行时态表达。另外hang非规则动词时,意为“绞死”,故C项与题不符。答案为A。
例8 She thought I was talking about her son, ______, in fact, I was talking about my son.
A. whom B. which C. while D. where
分析
while可作并列连词,用来表示比较或对比,译为“但是、然而”。正确答案是C。
例9 Is the house _____________ built of bricks
A. the one what is B. that is
C. the one that is D. when we
分析
此句如变成肯定句,就可以看出定语从句前面没有先行词。故B是错的。“one”是替代词,用来代替或避免重复某个可数名词。当所代替的词前有冠词时,“one”前必须有冠词。所以,C是正确的。另外,the one之后是定语从句,A和D不符合句子结构和句意。
例10 Mistakes in the printing should _____________ before the book is published.
A. point out B. point to C. be pointed out D. be pointed to
分析
“point”在此句中是及物动词,“point sth. out”其意为“指出某事”,所以,C项是正确的。B项“point to”是指向,不符合句子意思,不正确。D项,“point”是不及物动词,所以没有被动语态。
例11 They asked the children _____________ they _____________ the things in the lab that morning.
A. if…had touched B. whether…touched
C. where did…touch D. when…touch
分析
此句应注意宾语从句的时态,只因主句的谓语词是过去时,从句的动作先于主句的谓语动词,尤其从从句时间状语可以看出,它应是一个“过去的过去”的时态,即过去完成时。C项的结材不对,D和B项从句的时态不对。正确答案为A。
例12 —What’s happened to my library books? —_______.
A. I have no idea. B. You borrowed them from the library
C. You bought them yesterday D. They are about long life
精析
问句的句意为“图书馆的书怎么了?”根据这一信息句可知,B、C、D都不符合,故正确答案为A。
例13 The mother asked her son ______.
A. what did he do the day before
B. where did he find his last wallet
C. what time he got up that morning
D. that if he had finished his homework
精析
本题考查直接引语变间引语的问题,凡是在直接引语中是疑问句的变为间接引语时常变为陈述语序,但是对主语提问的问句语序不变。由此可知A项、B项应排除掉。D项连词重叠使用也不正确。故正确答案为C。
