一、英语判断强调句***把it***was***was***that去掉后***句子怎么看
the telephone是主语，rang是谓语。
我们把主从句提出来：When she was about to go to bed（从句）， the telephone rang.（主句）.这个句子中the telephone作主语，谓语是rang。主句“the telephone rang”句子成分已经完整了，所以前面的从句是状语从句。又因为是when引导的，所以是时间状语从句。
关于it is/was…that,在这个句子里强调的是状语。这种情况是很常见的。it is/was…that除了不能强调谓语，其它句子成分都可以强调。
二、用强调句造(两句)(It be that……)
强调句贯穿整个高中，但是我们是高二的时候讲的，其实高一也讲过不过不记得了
在英文中，句子的主语、宾语、状语都可以写进一定的句式里以表示对它的强调。它们是：
1. It is/ was+被强调的部分+ that( who, which)+句子的其他部分,
2. What… is/ was…这种句式就称为强调句。
强调句主要有两种形式：
1. It is/was+被强调的部分+ that(who,which)+句子的其他部分
下面我们以两个句子为例来演示强调句的构成。如：
1）Western health-care system are spending huge sums of money
on the surgical treatment of the disease.
西方国家医疗保健机构在心脏病的手术治疗上开支巨大。
强调主语
It is Western health-care system that(which) are spending huge sums of money on the surgical treatment of the disease.
正是西方国家医疗保健机构，在心脏病的手术治疗上开支巨大。
强调宾语
It is huge sums of money that( which) Western health-care system are spending on the surgical treatment of the disease.
西方国家医疗保健机构在心脏病的手术治疗上，开支确实是巨大的。
强调状语
It is on the surgical treatment of the disease that Western health-care system are spending huge sums of money.
西方国家医疗保健机构，就是在心脏病的手术治疗上付出了巨大的开支。
2）Ann Peters' husband rushed her to a nearby hospital last night.
主语宾语状语
昨晚，安妮.彼德的丈夫立即送她去附近医院。
强调主语
It was Ann Peters' husband that(who) rushed her to a nearby hospital last night.
昨晚，正是安妮.彼德的丈夫，立即送她去了附近医院。
强调宾语
It was her(she) that(who) Ann Peters' husband rushed to a nearby hospital last night.
昨晚安妮.彼德的丈夫立即送的是她，去附近医院。
强调状语
It was to a nearby hospital that Ann Peters' husband rushed her last night.昨晚安妮.彼德的丈夫立即送她去的就是一家附近的医院。
强调状语
It was last night that Ann Peters' husband rushed her to a nearby hospital.
就是在昨晚，安妮.彼德的丈夫立即送她去附近医院。
要点提示：
1）当原句叙述的是现在或者将来发生的事情用"It is… that…"的句式（如例句1）；当原句叙述的是过去发生的事情则用"It was… that…"的句式（如例句2）。
2）在这种强调句式中，一般用that引出句子的其他部分。如果被强调的部分是表示人的意义的名词时，可以用who代替that引出句子的其他部分；如果被强调的部分是表示事物意义的名词时，可以用which代替that引出句子的其他部分。但是，无论被强调的部分是表示地点、还是表示时间意义的名词，都不可以用where或者when。例如：
It is that man who(that) is teaching our English.
就是那个人教我们英语。
It was my telephone number which(that) Miss White happened to know.
怀特小姐碰巧知道的就是我的电话号码。
It is in front of the religious leader that the bride and groom stand together to be married.
新郎、新娘通常就是一起站在宗教头领面前举行结婚。
2）如果被强调的部分是人称代词，应该用该人称代词的主格形式；在口语或非正式文体中也可以用其宾格形式。
It was she(her) who told the police.就是她报告警察的。
It was you who we were talking about.我们刚刚谈论的就是你。
3）没有强调句子谓语的强调句，但有其通常的强调手段：do/ does/ did+动词原形。例如：
I do believe that he is an honest man.我的确相信他是老实人。
She does like literature.她确实喜欢文学。
They did go to see you yesterday, but failed to meet you.
他们昨天的确去看过你，但没见到你。
4）What… is/ was…
"What… is/ was…"是名词从句结构，也是强调句的另一种构成形式。它常用来强调主语、宾语。如果所叙述的是现在或者将来发生的事情用"What is… that…"的句式；如果所叙述的是过去发生的事情用"What was… that…"的句式。例如：
What he wishes most is to become a pilot.（强调宾语）
他最希望的是成为一名飞行员。
What interested me most in that movie was the beautiful scenery of Alps.（强调主语）
那部电影使我最感兴趣的是阿尔裨斯山那美丽的风景。
What I like is her speaking manner.（强调宾语）
我喜欢的是她说话的风度。
What encouraged us was the example he set for us.（强调主语）
给予我们鼓励的是他为我们树立的榜样。
三、英语语法--it was...that强调句的用法问题
1.一般情况用It is(was)……that…如：
He read three books in the library yesterday.
我们分别可以强调主语、宾语、地点状语和时间状语。如：
It was he who(that)read three books in the library yesterday.(强调主语)
It was three books that he read in the library yesterday.(强调宾语)
It was in the library that he read three books yesterday.(强调地点状语)
2.当被强调部分指人时，可用that，也可用who；指物时，只用that,如：
It was Tom who(that)I met last week.
It is a new boke that his brother wants to buy.
3.强调状语时，只用that,不用when、where.如：
It is at 5 o'clock that the train will arrive.
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：
It is he who is late. It is they that were late.
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：
Was it ten years ago that his father died?（他的父亲是十年前去世的吗？）
When is it that you will set off?（你到底什么时候出发？）
6.“not…until…”句型的强调结构为“It is not until…that…”应注意把否定词not转移到until前面。如：I didn't go home until rain stopped.(直到雨停了我才回家)。
强调句为：It was not until rain stopped that I went home.
I didn't know the news until yesterday.(直到昨天我才知道那个消息)
强调句为：It was not until yesterday that I knew the news
四、it is that 主语从句和强调句的区别
最简单易懂的讲解，
例如，Danny broke the window yesterday.
强调Danny---- It is Danny who broke the window yesterday.
强调yesterday----It is yesterday that Danny broke the window.
特点：被强调的部分原本是后面句中的某个成分。被提到前面加以强调了。
It was my suggestion that made him confident of success.这就是强调句。
正是我的建议使他对成功有了自信。
It is my suggestion that he needs more practice.
他需要更多的练习是我的建议
最后这句就是主语从句，it指代后面的that he needs more practice作主语。
my suggestion不是that he needs more practice中的一个成分。
