《Unit 3 Language in use》语法解析
whether/if及疑问词引导的宾语从句
上一模块中我们学习了that引导的宾语从句,在本模块中,我们来学习另外两类宾语从句——whether/if引导的宾语从句和疑问词引导的宾语从句。
1.whether/if引导的宾语从句
如果我们要表达像“他不知道他们周六是否会去植树”或“我记不清以前是否见过他”这样的不确定的概念时,从句就要用whether或if来引导,不能用that。例如:
● He does not know whether they will plant trees on Saturday or not.
他不知道他们周六是否会去植树。
● He asks whether/ if we will go fishing on Sunday.
他问周日我们是否会去钓鱼。
● Tom wants to know whether/ if he needs to come early tomorrow.
汤姆想知道明天他是否有必要早来。
同学们可能会问,这里有两个引导词,一个是whether,一个是if,应如何选择呢?在宾语从句后面没有or not的情况下,一般来说两个词都可以用。如果从句后面还有or not的话,一般就要选择whether,构成whether...or not的结构。
2.疑问词引导的宾语从句
通过本模块的学习,相信同学们已经注意到,有的宾语从句既不用that引导,也不用whether或if引导,而是用when,where,how或why等疑问词引导,这是从句意思表达的需要。例如要表达“他问什么时间出发”时,句中的“什么时间”必须用一个疑问词才能表达。如果遇到“什么时间、什么地点、什么方式、什么原因”之类的疑问时,我们就要使用相应的疑问词来引导从句。但是同学们一定要注意,在疑问词引导的宾语从句中,一定要用陈述句语序。例如:
● He asks how we can help protect the environment.
他问我们怎样才能为保护环境出力。
● I do not understand why they like computer games so much.
我不理解他们为什么如此喜欢电脑游戏。
● They have not decided where they should go for the holiday.
他们还没有决定到什么地方去度假。
● Do you know when we will hold the sports meeting?
你知道我们什么时候开运动会吗?
