live in and live等几个问题一.I don't konw why Lucy lives 我不知道露西住哪儿I visited the room which they lived in 我参观了他们居住过的房间前一句不用in为什么后面要用in二.详细说明动名词,分词和不定
I don't know where Lucy lives.
where 是 副词 这里可看作 which house (Lucy lives) in
总之就是which/what + 介词 的 合成
所以 I visited the room which they lived in.
也可以说 I visited the room where they lived.
动名词 就是 应该用动词 但是语法要求用名词 就改成动名词
比较典型的是 介词后面一定要跟名词 但如果要跟动词 就改称动名词
如 We played basketball instead of playing football.
分词就是除了动名词之外的 都是 可以作为定语补充修饰对象
There is a boy standing there.补充 站在那里
不定式除了有表示将来的含义之外 作主语与动名词没有什么区别
To protect / Protecting wild animals is necessary.
不定式应该很好区分啊
I want to be a doctor.
to 是不定式的标志 一定跟 动词原形

1.
live in的意思是“住进去”,live则是“生存/生活”。
如:
This room is too dirty to live in.(住进去嫌脏,但不至于住进去就活不成)
We have too little food for us to live. (没食物就活不下去了,所以用live)
3. 因为be之前是to,to之后一定跟原形,所以只能用...

1.
live in的意思是“住进去”,live则是“生存/生活”。
如:
This room is too dirty to live in.(住进去嫌脏,但不至于住进去就活不成)
We have too little food for us to live. (没食物就活不下去了,所以用live)
3. 因为be之前是to,to之后一定跟原形,所以只能用be
2的篇幅比较长,我放在最后:
动词不定式就是我们常说的to do形式,其中的动词是以原形出现的,情态动词加动词原形就是因为情态动词要求接不带to的不定式,也就只剩动词原形了。
分词包括过去分词和现在分词,拿fall为例,fallen为过去分词,falling为现在分词。fallen leaves表示落叶(在地上),falling leaves表示落叶(正在下落)。
动名词的形式与现在分词是一样的,但是意义上稍有区别,例如:
a sleeping bag,这里的sleeping是动名词,表示的是a bag for sleeping.
a sleeping baby,这里的sleeping是现在分词,表示的是a baby who is sleeping动词不定式概述
一 不定式的体
1. 不定式的一般式(to do)表示不定式的.动作将要发生或与谓语动作同时发生.
2 不定式的进行体(to be doing)表示不定式的动作正在发生.
不定式的完成体(to have done)表示不定式的动作在谓语动作之前发生.
二 不定式的逻辑主语
1 不定式的逻辑主语常不出现在句中.
2 句子的主语,宾语有时是不定式的逻辑主语.
3 不定式前"for+名词/代词"结构中的名词或代词也可以用来表示不定式的;逻辑主语.
4 在"It+be+形容词+of+名词/代词+to do"结构中,名词或代词为不定式的逻辑主语.该结构中的形容词通常用来表示人的品质.例如:kind, good, nice, bad, cruel, honest, bold, thoughtful, right, wrong, wise, clever, silly, foolish, careless, rude等.
例如:It's very kind of you to cal to tell me about the conference.
三 不定式的否定式
不定式否定式由not/never +to do构成
四 不定式的句法功能
1 不定式做主语
1)To say something is one thing; to do it is another.
2)It is not a good idea to build houses along the lines where two of the earth's plates join together.
注:充当主语的不定式即可置于句首,位于谓语动词之前,也可作为句子的真正主语置于句末,用作形式主语.
2 不定式作表语
3)Her uncle seems to be acting rather strangely towards her these days.
4)The purpose of the fence is to keep out a type of wild dog called a "Dingo".
5)One suggested answer is for farmers to limit the number of their cattle.
注:充当表语的不定式一般位于be ,seem等系动词后.
3 不定式作宾语
6)Shylock agreed to lend Antonio money on one condition.
注:充当宾语的不定式位于及物动词后.常用不定式作宾语的动词有:agree, plan, determine, dare, refuse, hope, wish, expect, promise, choose, pretend, decide, manage, intend, offer, afford, demand.
7)The dusty air makes it difficult to get a clear picture of space.
注:充当宾语的不定式如果有自己的表语,则可用代替只个不定式作为形式宾语,而作为真正宾语的不定式则放在表语之后.以it作为形式宾语的这种结构常用在think, feel, find, make, consider等动词之后.
big and strong.
4 不定式作宾语补足语
8)The powder made from fish, blood and bones will make the cabbage plants grow big and strong.
9)Portia told Bassanio to go to his friend at once.
注:在下列动词后作宾语补足语的不定式通常不带to.这些动词是observe, notice, see, hear, watch, have, feel, make, let.但上述动词转换为被动语态时,其后的不定式须带to.例如:The cabbage plants will be made to grow

第一句应该是I don't konw where Lucy lives
I visited the room which they lived in
前一句不用in为什么后面要用是因为where =in which用于引导一个地点状语从句。
第二句中的in 实际是和which 搭配,也就是说:I don't konw where Lucy lives =I don't...

三.为什么有些句子里会用到be ,不用am is are(将来时除外,请举例说明)如 I want to be a doctor 我想成为一名医生
动词分为be 动词(如be /become)和行为动词(V,如:come /go )在不定式,情态动词后要用动词原形,而am, are, is是be的现在式, was, were是be的过去式; been是be的过去分词; being是be的现在分词动词不定式的形式是to+动词原形(be动词/行为动词:V)如:I want to be a doctor.我想成为一个医生。 I must be/become a doctor .我必须成为一个医生
