Unit 7单元知识清单Section A一、基础知识清单二、知识点清单知识点①：need教材原句I need a sweater for school.1. need用作实义动词，意为“需要”，其后可接名词、代词或动词不定式作宾语，此时need 有人称、数和时态的变化，句型变化时需借助助动词。
We need much money now.我们现在需要很多钱。
－Does he need any help?他需要帮助吗？－Yes,he does./No,he doesn't.是的，他需要。
／不，他不需要。
need 用法歌诀1.实义动词表“需要”，后接名、代、不定式。
need后接动词的－ing形式，主动形式表被动。
2.情态动词表“需要”，没有时态数人称的变化。
后面直接跟动词原形，多用于疑问和否定。
用法辨析need to do need doingneed to do“需要去做”，动词不定式做宾语。
主语是动词不定式所表示的动作的逻辑主语，主语多为“人”。
need doing“需要被做”，主语是动词－ing形式所表示的动作的逻辑宾语，主语多为“物”。
The boy needs to buy a pair of shoes.这个男孩需要买双鞋。
The shelf is broken. It needs mending.这个架子坏了。
它需要被修理。
拓展（1)need还可做情态动词，意为“需要”，这时need没有人称和数的变化，其后接动词原形，变否定句时，要在need后加上not,变疑问句时，要把need提到句首。
You needn't clean the room now. 你现在不必打扫房间。
Need we do our homework first?我们需要先做家庭作业吗？（2)needn't用于must开头的一般疑问句的否定回答。
－Must we finish our homework now?我们必须现在完成家庭作业吗？－No,you needn't.不，你们不必。
