POINT语法说明
need
■
In Srf there are two separate verbs need.在英国英
语中有两个各不相哼的动词need。
■
Need as a main verb has the question form do you need?, the negative you don’t need and the past forms needed, did you need? and didn’t need. It has two meanings. * need作主要动词时，疑问式为 do you need?,.否定式为 you don’t need,、过去时为 needed、did you need?和 didn’t need。其含义看二：
1.
to require something or to think that something is
necessary 需要或认.有必要：Do you nm/
help?你需要帮助码？I needed to get some sleep,
我需要睡一会jL:。2..to have to or to be
obliged to do sth 必须或一定要：州/•〃 we need fo show owr passpo/ts?我们要出示护照吗？
■
Need as a modal verb has need for all forms of the present
tense, need you? as the question form and need not (needn’t).as the negative. The past is need
,have, needn’t have. It is used to say that something is or is
not necessary. * need作情态动词时，现在时 均作need,疑问式夫need you?,否定need not
,(needn’t),过去时为 need
have、needn’t have,用以" 表示某i有必要或痠有必要：/Vmy / pay f心vv/io/e flwownt now?我必须现在全部付清吗？
儀 In
AMmf only the main verb is used. This leads to some important differences in
the use and meaning of need in British and American English.在北美英语
中，need仅作主要动词，故need的用法和含义在英
国英语和北美英语中有些重要差异。
■
In NAmE it is more common for need to be used to speak about what is necessary, rather
than about what you must do.北美英语舍常用need表示有必 要，M非必定要做某事：/ don’t /7m/ to go home yet—it's still early. [BrE and NAmE = it isn^t necessary)
我不必现在回家，时间还早。(英国英语和北美
英语均为“不必”..)：◊ You
don’t need to go home yet—we never go to bed before
■
The difference is even more noticeable in
the past tenses.在过去时中差别單日月M: He need
to go to hospital, but he went just to reassure
himself.
(AWm£)他用不着去医院，去了只是想让自己放心
点。（北美英语）◊ We have 夸one to
hospital, but he went just to reassure himself. [BrE =he t/wf wflsnY necesso/y)也;4s1不必
去医院的，去了只是想让-己放^1、点。(英国英语
意为“他做了不需要做的事”）◊Wed/加to go to hospital after all~he only
had a few bruises.
(8nE
= he didn’t go)其实他无须去医院，他只是有点
碰伤。（英国英语意为“他没有去”）
