人教版英語必修一知識點

　　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?接下來小編為你整理了，一起來看看吧。

　　：陳述句的變化規則

　　直接引語如果是陳述句，變為間接引語時，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

　　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，變為間接引語時，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

　　：疑問句的變化規則

　　如果直接引語是疑問句，變為間接引語時要把疑問句語序變為陳述句語序，句末用句號。

　　一般疑問句：如果直接引語是一般疑問句，變為間接引語時，謂語動詞是say或said時，要改為ask 或asked,原問句變為由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，變為間接引語時，仍用原來的引導詞，但疑問句要變為陳述句。例：

　　“What do you want?” he asked me.

　　→ He asked me what I wanted

　　：定語從句

　　概念：在複合句中，修飾名詞或代詞的從句叫做定語從句。

　　成分：先行詞，即被定語從句修飾的名詞或代詞;關係代詞：that，which，who賓格為whom,所有格為whose;或者關係副詞where，when，why等。關係代詞或關係副詞處在先行詞和定語從句之間，起著連線主從句的作用。
