一、
“It is that”强调句是一种通过将句子的某个成分提前到句首,以加强其重要性的结构。它通常由“It is/was + 被强调部分 + that/who + 其余部分”构成。这种句型可以强调主语、宾语、状语等成分,尤其在口语和写作中使用广泛。
需要注意的是,“It is that”强调句不能用来强调谓语动词,且在疑问句或否定句中需适当调整结构。此外,根据时态不同,可使用“It was that”来表示过去的情况。

- It was not until 2020 that he returned.
- It is not the teacher who is responsible.

四、常见误区
- 混淆强调句与定语从句:
强调句强调某一成分,而定语从句则对先行词进行补充说明。
- 强调句:It is the man that helped me.(强调“the man”)
- 定语从句:The man who helped me is my friend.(描述“the man”)
- 误用“that”和“who”:
“that”可用于人或物,“who”仅用于人。
- 正确:It was the girl that won the prize.
- 正确:It was the girl who won the prize.
