Unit 14 Roots

典型例题

　　1.Is ________ necessary to tell everything to his father?
　　A. that B. this C.－ D. it
　　答案为D。考查it作为形式主语的用法。it在这儿代替不定式作主语。it还可以代替动名词和主语从句作形式主语。

　　2.I didn't feel ________ possible for them to finish the work on time, but I was wrong.
　　A. its B. it C. that D. this
　　答案为B。考查it作形式宾语的用法。设在本句中代替不定式复合结构作形式宾诺，同时还要注意到，it可代替动名词或宾语从句作形式宾语。it's是it has或 it is的编写，在此句中不能用。

　　3. ________ is two hours' ride from my house to our school.
　　A. It B. That C. Distance D. This
　　答案为入考查it指距离的用法。it在此相当于distance。it也可用来指天气与时间等。

　　4. ________ no use regretting what you have done.
　　A. It's B. That's C. What's D. There's
　　it在习惯用语中的用法。“It's no use（good）doing sth．”含义为“……是没有用的”。There is no use (need, harm, hurry)in doing sth．是动名词短语作介词宾语。答案为A。

　　5. ________ happened that I was there.
　　A. There   B. It    C. This    D. That
　　考查it作动词的主语。it后接that从句或as if从句，成为seem, appear, happen, occur, follow等动词的主语，译成中文时，可省略。It happened that...…意为“……碰巧……”。此句不是作that…的形式主语。答案为B。

　　6.She was shivering           cold.

　　A. for    B. with    C. by    D. as

　　答案：B

　　解题策略  读题后，我们可以知道“她正冷得发抖”。虽然A项的for 在表示原因时，指的是由于外在的原因，且这种原因只能对谓语行为作解释，不能成为谓语的行为的直接原因；C项的by 在表示原因时，只对谓语行为方式作出解释，如：He took my seat by mistake. D项在表示原因时，它必须后接一个原因状语从句。因此，该题正确答案为B项，with 用在这里既能表示原因，又能表示cold 与shivering是伴随的状态。

　　错误辨析  本题的解题错误是由于对上述四个选项表示原因的含义及用法不清楚造成的。

　　7.Man is born_________ free yet everywhere he is_________ chains.

　　A. to be…in　　B. being…by 　　C./...in　　D./...by

　　此题主要考查be born + n./adj. (生来就是，天生就是)以及in chains（受束缚）两个语言点，因此正确答案是C。注意搭配be born +n./adj. 不能接be 或being。如：

　　He was born a poet. 他是天生的诗人。

　　No man is born wise. 没有人生来聪明。

　　The prisoner was led off the boat in chains. 囚徒带着镣铐被从船上带走。

　　8.John hit_________.

　　A. him on the head　　B. him on his head

　　C. him in the head　　D. him in his head

　　此题正确答案是A (him on the head), hit + sb. + in/on +the+身体部分表示打某人部位（其中的the不可用物主代词代替），这是英语的习惯用法。打在head, shoulder, back                    等坚硬结实的部位用on, 打在eye, face等柔软多肉部位用in。如：

　　She hit Jack in the eyes. 她打杰克的眼睛。

　　The teacher patted the boy on the shoulder. 老师拍男孩的肩膀。

　　9. He said nothing but sat ____.

　　A. silently smoked　　B. silently to smoking

　　C. silent smoked　　　D. silent smoking

　　此题正确答案是D(silent smoking), 此题主要考查形容词和动词-ing形式作状语，表示时间、原因、伴随状况等。如：

　　Afraid of being late, they drove fast. (= Because they were afraid of being late, they drove fast. )

　　Eager to improve farming conditions, they tried out this new crop on a large area.

　　因为渴望改善耕作条件，他们在大块土地上试验试作物。

　　Nobody wants to sit here doing nothing.

　　谁也不愿坐在那儿什么也不干。

　　10. —Hello! May I speak to Li Ling?

　　　　—Yes. ______.

　　A. You’re speaking to Li Ling　　B. I’m Li Ling

　　C. I’m speaking　　　　D. Speaking

　　此题正确答案是D(Speaking)。打电话时，询问和回答均有习惯用法，回答语“我是李林”可用This is Li Ling speaking. 或It’s Li Ling here. 或简单一句话Speaking。选项A、B、C均不符合英语电话用语习惯，应予排除。如：

　　—Hello, may I speak to Bill, please? 喂，我要和比尔通话。

　　—This is Bill speaking. 我是比尔。

　　—Bob! You are wanted on the phone. 鲍勃，有人打电话找你。

　　—Coming. 我来了。

　　—Hello. Can I speak to Peter, please? 喂，我要找彼得通电话。

　　—Just a minute, please. I’m sorry, he’s not here right now. Can I ask who’s calling? (或：Who’s calling /speaking, please?) 请等一等，对不起，他现在不在家。请问你是谁？　

　　—Yes, It’s Bob here. 我是鲍勃。
