职称英语理工类考试辅导：语法句型技巧

职称英语理工类考试辅导：语法句型技巧常见的强调句构造是it引导的句子。

Itis(was)被强调局部+that(who)+句子其他局部。

此构造强调的成分仅限于主语，宾语和状语。

Itisfromthesunthatwegetlightandheat.

ItwasnotuntilIhadreadyourletterthatIunderstoodthetruestateofaffairs.

使用此句型时,应留意以下几点。

(1)一般状况用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)当被强调局部指人时,可用that,也可用who;指物时,只用that,如:

ItwasTomwho(that)Imetlastweek.

Itisanewbokethathisbrotherwantstobuy.

(3)强调状语时,只用that,不用when、where.如:

Itisat5o”clockthatthetrainwillarrive.

(4)被强调的局部是主语时,留意句子的谓语动词和被强调的主语保持全都。如:

Itishewhoislate.Itistheythatwerelate.

(5)一般疑问句的强调句为“Is(was)it+that…?“;特别疑问句为:“特别疑问词+is(was)+that…?“构造。如:

Wasittenyearsagothathisfatherdied?他的父亲是十年前去世的吗?

Whenisitthatyouwillsetoff?你究竟什么时候动身?

(6)“not…until…“句型的强调构造为“Itisnotuntil…that…“应留意把否认词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.

原句:Myfatherdidtheexperimentinthelabyesterdayevening.

强调主语:Itwasmyfatherwhodidtheexperimentinthelabyesterdayevening.

强调宾语:Itwastheexperimentthatmyfatherdidinthelabyesterdayevening.

强调时间:Itwasyesterdayeveningthatmyfatherdidtheexperimentinthelab.(留意不用when)

强调地点:Itwasinthelabthatmyfatherdidtheexperimentyesterdayevening.

C.倒装句：(这是我们在阅读文章时常见到的句式。)
