在英语中怎样把陈述句改成强调句?

It is I that am your English teacher.
把需要强调的部分直接放在It is ...that之间,其余部分就直接放在that之后就可以了.
注意以下几点：
1.强调句只能强调主语、宾语、状语,不能强调定语和谓语.
2.强调句只有两个时态It is和It was,选择的原则要看原句的时态,如果原句是过去的时态,那么强调句就应该是It was,否则的话,就是It is
3.当强调状语的时候,要把介词同时放在It is/was ...that之间,比如It was at 8:00 that I met him.

It is I that is your English teacher.
It is ...that...是强调除谓语之外的其他成分的句型.

It is I that am your English teacher.
It is ...that...是标准的强调句型 强调的是that前面的成分
直接把句子拆开填进去就行了
