2021届高中英语新高考语法核心考点专项复习（09）强调句和倒装句知识点整理总结

2021届高中英语新高考语法核心考点专项复习（09）强调句和倒装句知识点整理总结    强调句型的基本句式为： It is /was + 被强调部分 + that 或 who（只能指人） + 句子的其余部分。被强调部分指人时，引导词用 who 或 that，被强调部分为疑问代词 who 时，为了避免重复，只能用 that，其余情况一律用 that。如： It is I who was present at the meeting last Friday. 上周星期五是我出席这个会议的。 It was because he worked hard that he succeeded. 他是因为努力工作才取得成功的。 It was with great pleasure that we learned of your son’s success. 我们非常高兴地了解到你儿子所取得的成功。 It was in the laboratory which Mr. Smith is in charge of that they did the experiment. 他们是在史密斯先生负责的那个实验室里做这个实验的。 It was not until she took off her dark glasses that I realized she was a famous film star. 直到她把墨镜取下来，我才意识到她是个著名的电影明星。 It was only when I read his poems recently that I began to appreciate their beauty. 只是当我最近读到他的诗时，我才开始欣赏这些诗的美。   注： a. 有时某些状语从句，主语从句，定语从句因结构相似，容易与强调句型混淆，可用如下方法判断是否为强调句型：将 It is … who / that 去掉，如果句子成立 (有时要调整语序 )，则属于强调句型，否则就不是。如果是时间 it，则引导词需选用引导时间状语从句的从属连词 when, since, before 等，如为形式主语 it，则引导词需选用引导主语从句的与句型相适应的连词，辨别是何 it，应注意时态和引导词的关系。   当被强调部分是句子的时间状语时应特别注意区别：It+ be + 时间 +
