need常考的就4类题：

选形式、语法填空变形、句型转换、改错。

1.单选：先看后面接什么

need+动词原形→情态，多用于否定/疑问：needn't go

need+to do→实义：needs to go

need+doing→表被动：

The  flowers 

need watering=need to be watered 

2.语法填空：给need让变形

肯定句看人称：She needs help.

过去时加-ed：They needed time.

被动含义填needed：the string needed to fly kites

3.句型转换：情态vs实义互改

needn't  do=don't need to do（都是"不必"）Need I go?=Do I need to go?

4.短文改错：最爱挖这几个坑

need后漏了to：

❌need go→✅

need to go第三人称没加s：

❌she need→✅she needs

needn't后加了to：

❌needn't to go→✅needn't go
