人教版高一英语重点语法总结
同学们还在头疼到底应该记哪些语法嘛?今天跟小编来看看有哪些重点语法吧!
Unit1:
直接引语和间接引语(一)
直接引语：直接引述别人的原话。一般前后要加引号。
间接引语：用自己的话转述别人的话。间接引语在多数情况下可构成宾语从句且不要加引号。 例：Mr. Black said, “ I’m busy.” Mr. Black said that he was busy.
变化规则
1. 陈述句的变化规则
直接引语假设是陈述句，变为间接引语时，用连词that(可省略)引导，从句中的人称、时态、指示代词、时间状语、地点状语都要发生相应的变化。
(1)人称的变化——人称的变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 your room.” → He told me that he had left his book in my room.
例： “I don’t want to set down a series of facts in a diary,” said Anne. →Anne said that she didn’t want to set down a series of facts in a diary. The boy said, “I’m using a knife.” → The boy said that he was using a knife.
▲注意：假设直接引语是客观真理，变为间接引语时，时态不变，
如： He said, “Light travels much faster than sound.”
He said that light travels much faster than sound.
(2)指示代词、时间状语、地点状语和动词的变化
3. 疑惑句的变化规则
假设直接引语是疑惑句，变为间接引语时要把疑惑句语序变为陈述句语序，句末用句号。 (1)一般疑惑句：假设直接引语是一般疑惑句，变为间接引语时，谓语动词是say或said时，要改为 ask 或asked,原问句变为由if/whether 引导的宾语从句。
例:“Do you think a diary can become your friend?” the writer says. → The writer asks us if we think a diary can become our friend.
(3)尤其疑惑句：假设间接引语是尤其疑惑句，变为间接引语时，仍用原先的引导词，但疑惑句要变为陈述句。
例：“What do you want?” he asked me.
→ He asked me what I wanted
Unit2:

3.祈使句的变化规则
假设直接引语是祈使句，变为间接引语时，要将祈使句的动词原形变为带to的不定式，并根据句子意思在不定式前加上tell/ask/order等动词，假设祈使句是否定句，在不定式前面还要加上not。
例：The hostess said to us, “Please sit down.”
→ The hostess asked us to sit down.
He said, “Don’t make so much noise, boys.”
→ He told the boys not to make so much noise.
Unit3:

① 瞬间动词的进行时在任何情况下都表示将来含义。

② 继续动词的进行时，只有在有将来时间状语或将来语境的情况下才可以表示将来含义。 An American professor is giving a lecture this afternoon.

An American professor is giving a lecture. 一个美国教授正在作报告。(进行含义)
