B: Yes, I’d like to(=I’d like to go to Ann's birthday party tomorrow).
B：是的，我想去。
I went there, because I wanted to(=l wanted to go there).
我到那儿去了，是因为我想去。
(3)有时不定符号“to”也可省略（主要不得在名词、形容词以及动词try等之后）。例如：
He has to get a job and he is ready (to).
他不得不找工作，并且他也准备这么做。
A: Can you start the car?
B: OK, I’ll try.
A：你能发动这车子吗？
B：好，让我试试。
(4) 在would like和want之后，通常不能省略“to”。例如：
A: Are you interested in playing football?
B: Yes, I would like to.
A：你对踢足球感兴趣吗？
B：是的，我想踢足球。
My parents encouraged me to be a lawyer, but I don't want to.
我父母鼓励我去当个律师，可我不想。
(5) 当want和like用于从句中（在when/ if/ what/as之后）对，动词不定式符号“to”常常省略。例如：
Come when you want. 你什么时候想来，就来吧。
You may go if you like. 如果想走，你可以走。
Also，around the area of Aswan there are a lot of important old temples，which date from about 1250 B．C．而且在阿斯旺地区的周围还有许多重要古庙，它们是公元前1250年左右建立的。
这是一个带有非限制性定语从句的复合句。非限制性定语从句用以补充前面内容的不足，它和主句的关系不十分密切。如果去掉，主句意思仍然清楚。从句与主句之间往往用逗号隔开，一般不用that引导。如：
He marred a doctor，which made his parents angry．他娶了位医生，使得他的父母很生气。
She had two sons，neither of whom was kind to her．她有两个儿子，没一个对她好的。
The dam, which is the biggest in the world, is 3,830 metres long.
这座水坝长3,830米，是世界上最大的。
(1) “…，which is the biggest in the world”是一个非限制性定语从句，它插在主句（The dam is 3,830 metres long）的主语和谓语之间，前后有逗号隔开。例如：
上一页 [1] [2] [3] [4] [5] [6] 下一页
The letter, which I got yesterday, lay there unopened.
这封信是昨天收到的，还没有拆开过哩。
(2) 3,830 metres long是名词短语，表示长度，在句中作表语。英语中常用“…metres long/ wide/ high”等表示长度/宽度/高度（=metres in length/ width/height），如课文中的：980 metres wide, 40metes wide, 500 kilometres long. 例如：
He is a basketball player; he is six feet tall.
他是篮球运动员，身高6英尺。
It was carved in the rock and had on the outside four large stone figures, each of which was 20 metres high.
这座庙宇是雕凿在岩石中的，外面有四尊巨大的石像。每尊石像有20米高。
（1）句中的each of which was 20 metres high是一个非限制性从句。句中had的宾语是four large stone figures，状语on the outside。这种定语从句是由“名词（代词或数词）+介词+关系代词”来引导的。又如：
In his house there are three rooms, each of which has a bed.
They lived in a house, the door of which opens to the south.
China has hundreds of island, the largest of which is Taiwan.
These books, two of which I have read, are interesting.
（2）除了of which外，还有of whom这种句型。即：“名词/代词/数词+of whom”
There are around 100 teachers in our school, most of whom are women.
These girls, the youngest of whom is my sister, will dance a waltz for us.
Her brothers, both of whom (three of whom) work in Scotland, ring her up every week.
(3)除了上述所举的名词、代词、数词外，some, all, none, several, few等词都可接of+ which/ whom的句型。
限制性和非限制性定语从句的区别
区别：
1)在形式上
限制性定语从句的关系词和先行词之间不用逗号分开。
非限制性定语从句中两者则用逗号分开。
Jack is the kind of people who prefers listening to talking. (限定性)
杰克是那种宁愿聆听，不愿讲话的人。
The students, some of whom were rather busy, did not spend much time on music. （非限定性）
这些学生在音乐上花的时间不多，他们中有些人的确很忙。
2)在意义上
限制性定语从句说明的是句中的先行词必不可少的情况，它用来限制先行词所指的范围，其内容与先行词关系密切；若去掉此定语从句，剩下的部分则含义不明确、意义不完整或意义完全改变。
非限制性定语从句则与先行词关系较松散，只是对先行词做进一步的解释、补充或说明；若去掉此定语从句，整个句子意义一样很明确，不会引起误解和歧义。请看以下例句：
