【答案】1.raised 2.was driving 3.will have finished 4.had read 5.happened 6.is covered 7.water 8.hasn’t happened 9.fixing 10.not to be
【解析】
1.句意:他们同意一旦筹到足够的钱,他们就会帮助建立一所夜校。
根据时间状语从句主从句时态要一致的原则,主句“They agreed”是一般过去时,推断从句的谓语动词也是一般过去时,raise的一般过去式是规则变化,词尾+ed;故填raised 。
2.句意:当我开车走的时候,一条狗突然跑过马路。
while引导的时间状语从句,主句“a dog suddenly ran across the road.”是一般过去时,从句动词drive为延续性动词,推断空格用过去进行时;故填was driving。
3.句意:到下周二我们将完成第五章。
根据时间状语“by next Tuesday”,表示到将来某个时间为止,判断用将来完成时;其谓语动词的结构是will have+ 过去分词;finish 过去分词是规则变化,词尾+ed; 故填will have finished。
4.句意:这是她读过的最难的文章。
从句的动作“read”发生在主句动词“was”之前,判断空格用过去完成时;其谓语动词的结构是had+ 过去分词;read 过去分词是不规则变化read,故填had read 。
5.句意:吉姆问在1949年中国发生了什么。
根据句中的时间状语“in 1949”,表示过去的具体时间,判断空格用一般过去时;happen的一般过去式是规则变化,词尾+ed;故填happened 。
6.句意:几乎四分之三的土地被水覆盖。
根据常识,地球表面大约四分之三被水覆盖,推断空格用被动语态;一般现在时被动语态谓语动词的结构是“is / are+ 过去分词”,主语“Almost three quarters of the Earth”是单数形式,故填is covered。
7.句意:当我还是个孩子的时候,我的邻居常让我给她浇花。
have sb do sth意为“让某人做某事”;判断空格填动词原形; water当名词意为“水”,当动词意为“浇水”;故填water。
8.句意:我真的不知道该说什么,因为这样奇怪的事情以前从来没有发生过。
主句的谓语“don't know”是一般现在时,根据句中的副词“before”推断从句的谓语动词用现在完成时,其结构为“has/have+过去分词”;从句的主语such a strange thing是单数形式,故填
hasn’t happened。
9.句意:他花了半个小时修理他的笔记本电脑。
sb spends+时间+ doing sth意为“某人花多长时间做某事”;由此推断空格填动名词;fix意为 “安装”,动词;故填fixing。
10.句意:他已经告诉过你不要再迟到了。
tell sb to do sth “叫某人做某事”;根据备用词not提示,推断空格填不定式的否定式—— tell sb not to do sth“叫某人别做某事”;故填not to be。
