六.只用whether不用if引导主语从句.
形式主语IT
有时为了考虑句子平衡(避免头重脚轻),通常在主语从句处使用形式主语it,而将真正的主语从句移至句末。
这分三种情况:
(1)对于以连词that引导的主语从句,通常用形式主语代主语从句:
It’sapitythathedidn’tcome.很遗憾他没来。
It’svitalthatwe(should)bepresent.我们出席是至关重要的。
Itwasintendedthatyoubethecandidate.大家的意图是让你当候选人。
Itisappropriatethatthistaxbeabolished.废除这个税是恰当的。
It’sunfairthatsomanypeopleshouldlosetheirjobs.竟有这么多人失业这是不公平的。
Thattheyshouldrefusetosignthepetitionrequiredgreatcourage.他们拒绝在请愿书上签字这是需要很大勇气的。
注意:
should用于虚拟语气
用于主语从句中
在“Itis+形容词/某些动词的过去分词+that从句”的结构中,从句的谓语动词用“(should)+do”虚拟语气形式来表示命令、要求和建议。
这些形容词和过去分词常见的有important(重要的)、essential(必要的)、necessary(必须的)、natural(自然的)、ordered(命令的)、demanded(要求的)、proposed(建议的)、required(要求的)等。
(2)对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从句:
Whethertheywouldsupportuswasaproblem.他们是否会支持我们还是一个问题。
Itwasaproblemwhethertheywouldsupportus.他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从句,通常直接将主语从句放在句首。
如:
Whatweneedismoney.我们需要的是钱。
WhatIwanttoknowisthis.我想知道的就是这一点。
有时也可将助用形式主语。
Itisclearenoughwhathemeant.他是什么意思很清楚。
(4)如果句子是疑问句,则必须用带形式主语it的结构:
Isittruethatheisthegirl’sfather?
他是那女孩的父亲,是真的吗?
Howisitthatyouarelateagain?
你怎么又迟到了?
三、连词that的省略问题
引导主语从句的连词that有时可省,有时不能省,其原则是:
若that引导的主语从句直接位于句首,则that不能省略;
若that引导的主语从句位于句末,而在句首使用了形式主语it,则that可以省略:
Thatyoudidn’tgotothetalkwasapity.很遗憾你没去听报告。
(that不可省)
Itwasapity(that)youdidn’tgotothetalk.很遗憾你没去听报告。
(that可省)
