三、句式详解

1. In India there is a national festival on October 2 to honour Mahatma Gandhi, the leader who helped gain India’s independence. 在印度,十月二日是一个全国性的节日,该节日就是纪念帮助他们获得了印度独立的领袖甘地的。

句中关系代词who引导的定语从句修饰Mahatma Gandhi的同位语the leader。同位语指的是句子中指代同一事物的词语、短语或从句,它和其前的名词构成同位关系。例如:

Mr Li, my English teacher, will be leaving on Tuesday, October 1. 李先生,我的英语老师,将于星期二,即10月1日离开。(My English teacher是Mr Li的同位语)

In this chapter we shall make use of only two of Newton’s laws, the first and the third. 本章我们将只使用牛顿的两个定律:第一定律和第三定律。(the first and the third为two of Newton’s laws的同位语)

同位语可以由名词从句担当。同位语从句中的that并不是从句结构中的一个成分,而是一个连接词,只起连接作用,无具体词义,但一般不能省略。例如:

The idea that computers can recognize human voices surprises many people. 计算机能够识别人的声音的想法使许多人感到惊奇。

The news that I have passed the exam is true.我通过了考试这一消息是真的。

2. The country is covered with cherry tree flowers so that it looks as though it might be covered with pink snow. 乡村掩映在樱桃花里,它看起来仿佛被粉红色的雪所覆盖。

as though意为“似乎;好像”,在句中引导表语从句。在通常情况下,as though所引导的从句的谓语动词多用虚拟语气,表示所叙述的情况与事实相反。例如:

Why is she looking at me as though she knew me?她为什么那样看着我?像是认识我似的。

He stood there looking at the train and laughing, as though to miss a train was the best joke in the world.他站在那里,望着火车哈哈大笑,好像误了火车是天底下最开心的事儿似的。

so that既可引导目的状语从句,也可引导结果状语从句,可以由以下几点进行区分:

1) 当表达“为了……”、“以便……”的含义时,引导的是目的状语从句;当表达“以至于……”、“因此”的含义时,引导的是结果状语从句。如:

If you do know, answer in a loud enough voice so that all the class may hear. 如果你的确知道,应大声回答,以便让全班同学都可以听见。

It rained hard the day before yesterday, so that she had to stay at home. 前天雨下得很大,因此她只好呆在家里。

2) 当从句的谓语动词有情态动词can, could, may, might, should等时,是目的状语从句;当从句里没有情态动词,且谓语动词是一般现在时、一般过去时或现在完成时等时态时,引导的是结果状语从句。如:

We stopped at Salt Lake City so that we could visit the monument to seagulls. 我们在盐湖城逗留是为了可以参观为海鸥修的纪念碑。

They have walked a long distance so that they are all tired. 他们走了很长的路,所以都很累。

3) 当so that之前有逗号时,引导的是结果状语从句;反之,引导的是目的状语从句。如:

You didn’t plan your revision well, so that you didn’t pass the exam. 你没有好好地按计划复习,结果你没考及格。

The teacher must speak slowly so that the students may understand him. 那位老师必须讲得慢些,以便所有的学生可以理解
