英语强调句问题句型是it was(is) for sb/sth that/who还是没有for .it was(is)

it was/is ...that/who...是强调句,但? 强调句型 it is 还是it was? 强调句it is（was) .that/who,其中it is（was)能不能写成it's/it was不能缩写么? It is /was for the first /second ...time that sb.do /did sth it is/was...that/who..强调句型都能强调什么句子成分?同位语可以吗? 英语中的强调句型 it is/was...that/who...中的that、who可以省略吗?最好有详解. it is/was adj.for sb to do sth.真正的主语是to do sth,sb是此句的宾语,又是to It is the house that I want to look for.是强调句型还是定语从句? 强调句 It is (was) 被强调部分+ that (who) + 句子其他部分 英语中的强调句型 it is/was +强调范围 that/who····这个强调范围就是表语吗? It is(was) +强调部分+that (who)+从句 是sth is important to sb还是 it is important for sb to do sth?
