Question

How long do you think _______ the conflict between Japan and China comes to an end?

A．will it be until	B．will it be when
C．it will be before	D．it will be that

Answer 1

C

試題分析：句意：你認(rèn)為還有多長時(shí)間中國和日本能夠結(jié)束沖突？do you think是插入語，它用疑問句的形式，它的后面應(yīng)該用陳述語氣，故排除AB；這里it wiil be +some time before +…表示還要過多久才能……。
點(diǎn)評(píng)：本題難度適中。插入語在近幾年的高考中經(jīng)常出現(xiàn)，有插入語的句子增加了試題的難度，考生如果分不清插入語與句子的其他成分，很容易判斷錯(cuò)誤；固定句式不僅在單選中考查，還會(huì)出現(xiàn)在完形和短文改錯(cuò)中。
即學(xué)即練：He made another wonderful discovery, ____ of great importance to science.
A. which I think is    B. which I think it is
C. which I think it   D. I think which is
解析：A。這是一個(gè)非限制性定語從句， which 在從句中作主語，代替 the discovery .做這類題目的方法是先將插入語 I think 去掉，然后再將句子還原成為 He made another wonderful discovery， which is of great importance to science. 問題就迎刃而解了。
