1、主语丛句:在复合句中起主语作用的句子被称为主语丛句,通常有这些连词连接,that / whether / if /, 连接代词who ,whose , what, which 或连接副词when , where , why , how ,等引出。如:
Whether we can rece the use of energy is important.我们是否能减少能量消耗是最重要的。
分析:这个句子是一个明显的主语丛句,句子中的whether we canrece the use of energy 则充当主语,它以一个句子的形式充当主语。
2、表语丛句:在复合句中起表语作用的句子称为表语丛句,表语丛句也由从属连词that ,whether[that 可省略],连接代词who , whose , what , which , 或者连接副词when , where , where , why , how等引出。如:
The trouble is where the lost wallet can be found。麻烦的是遗失的钱包到哪里才能才能找到。
分析句子中where the lost wallet can be found在is的后面表示为联系动词后的句子,为表语,所以充当表语丛句,在这里也看到了is这中形式,但它不表现为主语丛句,因为他头轻脚重。
3、宾语丛句: 由从属连词that ,whether / if 引导的丛句,that 此时无词意,常用在动词后。
Do you know why winter is colder than summer?你知道为什么冬季比夏季冷吗?
He said he had finished his studies when the war broke out.他说战争爆发时,他已经完成了学业。
4、连词whether可引导主语从句、宾语从句和表语从句,不可省。if引导宾语从句。
I don't know if/whether I should tell you.不知我是否应告诉你。
Everything depends on whether we have enough experience.一切都取决于我们是否有足够的经验。
5、that引导宾语:
I promised that if anyone could set me free,I would make him king over the earth.曾许诺如果有人把我放了,我就让他成为全世界的国王。
6.宾语从句的主语是this/that,或用this/that修饰主语时。
He said that that was a good idea.他说那是个好主意。
7.在直接引语中,主句和宾语从句被隔开时。
“I'm sorry to tell you,”he said,“that you didn't watch carefully enough what I did.”我很遗憾的告诉大家,你们没有仔细观察我所做的一切。
