Step3Grammar
定义：用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的连接词有：连词that,whether；连接代词who,what和which；连接副词when,where,how和why。
1)由what等代词引起的主语从句：
Whattheteachersaidtodaywasquiteright.老师今天说的话是十分正确的。
2)由连词that引起的主语从句：
Thattheyarebadlyinneedofhelpisquiteclear.他们急需帮助，这是十分明显的。
但是这类句子在大多数情况下会放到整个句子的后部去，而用代词it作形式主语。
3)由连接代词或连接副词以及whether引起的主语从句。
Whethertheywillsellthehouseisnotyetdecided.他们是否卖掉这所房子还没有决定。
4)whatever,whoever也可引导主语从句。
Whateverwassaidheremustbekeptsecret.这里说的话都应当保密。
Whoevermakesmistakesmustcorrectthem.凡犯了错误的人都必须改正。
注意:上述例句中的主语从句都是放在句首,但有时为了使句子结构平衡,避免“头重脚轻”,常用it作形式主语,而把从句放在后面。例如:
Itisapitythatshehasmadesuchamistake.她犯了这样一个错误,真是遗憾。
这样就构成了下面一些常用句型:
1)Itis+adj./n.+从句
Itisapity/shamethat...遗憾的是……
Itispossiblethat...很可能……
Itisunlikelythat...不可能……
2)It+不及物动词+从句
Itseems/appearsthat...似乎……
Ithappenedthat...碰巧……
3)It+be+过去分词+从句
Itissaidthat...据说……
Itisknowntoallthat...众所周知……
Itisreportedthat...据报道……
Itisbelievedthat...据信……;人们相信……
Itissuggestedthat...有人建议……
单个的主语从句作主语时谓语动词用单数；由and连接的两个主语从句作主语时，谓语动词用复数。

prevent,stop,keep与protect四者的常见结构为：
prevent...(from)doingsth.；stop...(from)doingsth.；keep...fromdoingsth.;均表示“阻止……做某事”。
上述三个结构中，在主动语态中stop与prevent后可省去from，但在被动语态中不可省略;而keep...from...中的from在任何情况下都不能省略。另外，
protect...from...表示“保护……不受……侵袭；阻挡；防御”。from后接能带来伤害或损害的事物。

happen强调偶然发生。
takeplace指按计划、安排发生；举行
breakout多用于指战争、火灾、疾病、疫情的突然爆发。
