课文重难点精析 (Unit 2, Book 7)

Asimov had both an extraordinary imagination that gave him the ability to explore future worlds and an amazing mind with which he searched for explanations of everything, in the present and the past. 阿西莫夫不仅有着超凡的想象力,使他有能力探索未来世界,而且还有着惊人的智力,使他能对现在的和过去的各种事物作出解释。

【点拨】这个句子很长,较难理解。句子的主要部分是:Asimov had both an extraordinary imagination and an amazing mind. 句中有两个定语从句…that gave him the ability to explore future worlds修饰an extraordinary imagination;…with which he searched for explanations of everything, in the present and the past修饰an amazing mind。而第一个定语从句中的不定式to explore future worlds又作定语修饰ability

with which是介词前置的定语从句。定语从句中经常出现“介词 + which/whom”,其中介词的选择是难点,所用介词或者与前面的名词搭配有关,或者与后面的动词或词组搭配有关。如:

He lost the pen with which he signed the important paper.

This is the person with whom I worked for ten years.

【拓展】

1. where =介词(in/at/on) + whichwhen =介词(on/in/during) + whichwhy = for + which

2. 如果介词属于一个固定词组的话,介词就不能提前。

【活学活用】用正确的介词加引导词填空。

(1) The school         I am studying is far away from here.

(2) Liu Mei studied in the high school from 1993 to 1996,        she went to Beijing University.

(3) Please pass me the book         the cover is broken.

(4) Can you tell us the reason         you were absent from school?

 

Key: (1) in which     (2) after which   (3)of which     (4) for wh
