基本信息
强调句型的判断 把“it, be，that”去掉，如果剩余部分句子结构仍然完整（被强调部分要还原到原位置），那么这个句子就是强调句；如果句子不完整，则不是强调句。如：（1）①it is he who / that often helps me with my english. ②it is on the hillside that we plant trees every year. ③it was because of bad weather that the football match had to be put off.(shanghai 2003, spring) 分析：去掉it is / was... that / who 句子后结构仍然完整，句意仍明确，都是强调句。 ④ it was 9 o'clock when we came back． 我们回来时是九点钟。 ⑤ it was 3 hours since we had come back． 我们回来已三个小时了。
