【needed】NEED被动的用法为什么有时候是need 有时候是 be+needed_英语_浮生梦魇TA0254
2017年15月06日发布
这2种的意义不同.
A+need doing/need to be done 表示是 “A+需要被做某事”
例The tree needs planting/The tree needs to be planted .指树要“被种”
A+be needed是“A被需要”
例Five more people are needed. 另外5个人被需要.
具体的你可以用百度Hi和我聊.

题1: NEED的所有用法.有needdoing这种用法吗?关于need的所有用法.[英语科目]
此乃我复制的...
need “need”既可以作情态动词,也可以作实义动词,但是它们的用法不同.
作为情态动词的“need”的用法与其他情态动词“can”,“may”,“must”的用法基本相同:在限定动词词组中总是位居第一,没有非限定形式,即没有不定式、-ing分词或-ed分词等形式;第三人称单数现在时没有词形变化;情态动词之间是相互排斥的,即在一个限定动词词组中只能有一个情态动词.下面是“need”作为情态动词的用法:
一、need表示“需要”或“必须”,通常用于否定句,疑问句,条件句.例如:
1.You needn't do it again.你不需要再做了.
2.He needn't worry about it.这件事他无需担心.
3.Need he do this homework first?他需要先做这些作业吗?
4.Need they fill in the form?他们需要填表吗?
二、在否定句中,可以用need的否定形式+不定式完成体.例如:
1.We needn't have worried.其实我们不必要慌.
2.You needn't have mentioned it.你本来不必提起这件事.
3.You needn't have said that when he asked.当他问的时候,你其实不必要说.
三、needn't后的不定式间或也能用进行式或被动语态.例如:
1.He needn't be standing in the rain.他不必要站在雨中.
2.We needn't be waiting in this place.我们不必要在这儿等.
3.The hedges needn't be trimmed thisweek.本周树蓠不必要整修.
四、其一般疑问句的答语,肯定用must,否定用needn't.
Need I go with her? 我需要和他一起去吗?
Yes,you must. 是的,你需要去.
No,you needn't. 不,你不必去.
“need”作为实义动词时,通常用法是:
人+need +to do
物+need +doing
物+need +to be done
另外,“need”作实义动词时后还可以直接跟名词.请看下面的例子:
It is a question that needs very careful consideration.这是一个需要慎重考虑的问题
很简单的方法区别情态动词与实义动词:当need为情态动词时,意思是“必要”,否定为"needn't",后面大多接动名词,表示动作;
当need为实义动词时,意思是“需要”,否定为"don't need",后面大多跟名词.
STH need doing =STH need to be done
啊对了.还有need作名词...意思就是需求.需要..比如 meet one's needs 满足某人需求.用法还有我还复制...
need n.需要, 必需, 必需品, 要求, 贫困the need to do the need of sth.
A friend in need is a friend indeed.
患难见真情.
I am in need of a laptop.我需要一台笔记本电脑.
I am in a crying need for $1,000. 我急需1000块钱
题2: 英语被动句中need的用法作情态动词和实义动词时用法一样吗[英语科目]
需要较全面、比较准确的回答吗?可以等着看我的回答哦!很快就补充上来.
一、用作情态动词
像绝大多数情态动词一样,没有人称和数的变化,后面接动词原形.主要使用于疑问句和否定句,也可以用于陈述句.
1、否定式:直接在need后面加not,缩写为 needn't,表示【不必】.
疑问式:直接将need提前到句子开头.
后面搭配:动词原形.
这三点是区分情态动词还是实义动词的常用标准.
例如:
——Need I come over to help you with the work?
——Thanks,With Tom helping us,you needn't .
You need finish the job before six a.m.
2、情态动词常考形式(见例句):
①——Must he stay with us this evening?
——No,he【needn't/doesn't have to】.
表示【不必】,要用needn't,don't have to,而不能用mustn't(禁止;不许).
②You【 needn't have told】 him the news,for he had been informed of it by his friends.
needn't have+过去分词
表示【过去本来没有必要做某事(却做过了)】.
二、实义动词
这时,它的用法和其他实义动词一样,都有人称和数的变化,后面需要接带to不定式.
1、 否定式:加助动词 do,did,does来表达.
疑问式:将助动词do,did,does提到句子开头,后面用动词原形.
后面搭配:带to不定式(在否定式中,不定式符号to可以省略).
例如:
We need to do more practice.
She needs another pen to write her homework with.
——Does he need to go to school on this Friday evening?
——No,he doesn't.
2、need表示“需要”,用法类似于want,require
The computer needs【 repairing.(主动式表示被动)】
=The computer needs 【to be repairesd 不定式被动式】.
3、被动结构的用法:
More new book 【are needed 】in our school library.
The work 【needs to be done 】at once.
三、need作名词的典型用法:
1、【There is no need】 for you to come again.
2、We 【are in great need 】of this kind of reading materials.
3、A friend in need is a friend in deed.【谚语】
患难见真情/患难朋友才是真正的朋友.
个人精心总结,纯粹手工制作.希望能够帮助你!
祝你开心如意!
