英語是高中的基礎學科，那麼必修一英語都有哪些知識點呢?接下來本站小編爲你整理了人教版英語必修一知識點，一起來看看吧。
直接引語如果是陳述句，變爲間接引語時，用連詞that(可省略)引導，從句中的人稱、時態、指示代詞、時間狀語、地點狀語都要發生相應的變化。
人稱的變化——人稱的變化主要是要理解句子的意思
例：1. He said, “ I like it very much.” → He said that he liked it very much.
2. He said to me, “I’v left my book in yourroom.”
→ He told me that he had left his book in my room.
時態的變化
直接引語 | 間接引語 |
一般現在時 | 一般過去時 |
現在進行時 | 過去進行時 |
現在完成時 | 過去完成時 |
一般過去時 | 過去完成時 |
一般將來時 | 過去將來時 |
過去完成時 | 過去完成時 |
例：
“I don’t want to set down a series of factsin a diary,” said Anne.
→Anne said that she didn’t want to set down a series offacts in a diary.
The boy said, “I’m using a knife.”
→ The boy said that he was using a knife.
▲注意：如果直接引語是客觀真理，變爲間接引語時，時態不變，如：
He said, “Light travels much faster thansound.”
He said that light travels much faster thansound.
指示代詞、時間狀語、地點狀語和動詞的變化
直接引語 | 間接引語 |
this | that |
these | those |
now | then |
ago | before/earlier |
today | that day |
yesterday | the day before |
tomorrow | the next/following day |
the day after tomorrow | In two day’s time |
come | go |
here | there |
the day before yesterday | two days before/earlier |
如果直接引語是疑問句，變爲間接引語時要把疑問句語序變爲陳述句語序，句末用句號。
一般疑問句：如果直接引語是一般疑問句，變爲間接引語時，謂語動詞是say或said時，要改爲ask 或asked,原問句變爲由if/whether引導的賓語從句。例:
“Do you think a diary can become your friend?”the writer says.
→ The writer asks us if we think a diary can become ourfriend.
2) 特殊疑問句：如果間接引語是特殊疑問句，變爲間接引語時，仍用原來的引導詞，但疑問句要變爲陳述句。例：
“What do you want?” he asked me.
→ He asked me what I wanted
