当需要强调句中的主语、宾语、状语时,我们常用“Itis(was)+被强调部分+that(who)”这种句型,使用此句型时,应注意以下几点.
1.一般情况用Itis(was)……that…如:
Hereadthreebooksinthelibraryyesterday.
我们分别可以强调主语、宾语、地点状语和时间状语.如:
Itwashewho(that)readthreebooksinthelibraryyesterday.(强调主语)
Itwasthreebooksthathereadinthelibraryyesterday.(强调宾语)
Itwasinthelibrarythathereadthreebooksyesterday.(强调时间状语)
2.当被强调部分指人时,可用that,也可用who;指物时,只用what,如:
ItwasTomwho(that)Imetlastweek.
Itisanewbokethathisbrotherwantstobuy.
3.强调状语时,只用that,不用when、where.如:
Itisat5o'clockthatthetrainwillarrive.
4.被强调的部分是主语时,注意句子的谓语动词和被强调的主语保持一致.如:
Itishewhoislate.Itistheythatwerelate.
5.一般疑问句的强调句为“Is(was)it+that…?”;特殊疑问句为:“特殊疑问词+is(was)+that…?”结构.如:
Wasittenyearsagothathisfatherdied?(他的父亲是十年前去世的吗?)
Whenisitthatyouwillsetoff?(你到底什么时候出发?)
6.“not…until…”句型的强调结构为“Itisnotuntil…that…”应注意把否定词not转移到until前面.如:Ididn'tgohomeuntilrainstopped.(直到雨停了我才回家).
强调句为:ItwasnotuntilrainstoppedthatIwenthome.
Ididn'tknowthenewsuntilyesterday.(直到昨天我才知道那个消息)
强调句为:ItwasnotuntilyesterdaythatIknewthenews.
