1(2)21. 强调句型的结构：It is/was+ 被强调部分 +that / who+ 句子的其余部分。强调句型主要用来强调主语、宾语、状语等句子成分。如果强调的部分是人，可用who, whom 代替 that 。例如：强调句型3Mr Smith bought a new car from the factory last year.史密斯去年从工厂买了一辆新车。强调主语：It was Mr Smith that/who bought a new car from the factory last year.去年从工厂买新车的是史密斯先生。4强调宾语：It was a new car that Mr Smith bought from the factory last year.史密斯先生去年从工厂买的是一辆新车。强调状语：It was from the factory last year that Mr Smith bought a new car.去年史密斯先生是从工厂买的新车。5强调句型的一般疑问句形式是： Is/Was it+ 被强调部分 +who ／ that+…? 例如：Was it from the factory that Mr Smith bought a new car last year?去年史密斯先生是从工厂买新车的吗？6特殊疑问句形式是：疑问词 +is ／ was+ 被强调部分 +that…? 例如：Where was it that Mr Smith bought a new car last year?去年史密斯先生是从哪里买的新车？72. 使用强调句的几个注意方面：（ 1 ） not until 结构用于句首时，主语和谓语通常用倒装语序。但在“ It is/was not until… that…” 句型中， that 后的主谓不倒装。例如：8Not until he came back did I know the truth. 直到他回来，我才知道真相。It was not until he came back that I knew the truth. 直到他回来，我才知道真相。9（ 2 ）被强调部分是主语， who ／ that之后的谓语动词应该在人称和数上与原句中的主语保持一致 :It is I who am right. 我是对的。It is he who is wrong. 他是错的。It is the students who are in need of practice. 学生需要练习。10（ 3 ）被强调部分是句子中的时间状语、地点状语、原因状语时，不能用 when, where, because ，要用 that 。例如：It was because of the heavy rain that he came late. 是因为大雨他迟到的。11（ 4 ）被强调部分既包括人又包括物，用that 不用 who 。例如：It was the things and people that they couldn’t forget.他们不能忘记的是这些人和事。12（ 5 ）强调句型用...
