( I在句中作主语） 我喜欢踢足球。You can ask me for advice. ( me在句中作ask宾语） 你可以向我咨询建议。2)宾格代词有
2、时可代替主格代词在比较级中，在不引起误解的前提下，有时用宾格代词代替主格代词(尤其是其后跟有同位语all时).Eg: He is taller than us all.他比我们都高。在情景对话中，当省去谓语时Eg: -Who can drive a bus? - Me. - 谁会开公交车？ - 我。表示惊奇、猜疑、反问、不满、厌烦等情绪。Eg: Why me? (表示一种不满的情绪） 为什么是我？用作表语时，口语中常用宾语Eg: - Who is there? - Its me. - 谁在那？ - 是我。3)三个人称的代词同时出现时，其单数人称排列顺序一般是 “2 - 3 - 1”；复数人称排
3、列顺序一般为“ 1 - 2 - 3”Eg: You,she and I all enjoy music.你我她都喜欢音乐。 注意：在承担责任、承认错误、检讨工作时，排列顺序为“ 1 - 2 - 3”Eg:I and she are to blame for the accident.她和我都应该为这次事故负责。* it的用法it用作人称代词，代替事物。1)代替刚提到的过的一件事，既可以直接一个具体的东西，也可以指前面所谈的事情或情况。Eg: Please give it to me. 请把它给我。2)习惯上用it代替this/that等指示代词。Eg: -Whos this? -It is m
4、y mum. - 这是谁？ - 它是我妈妈。3)it 常代替无法或没有必要分性别的人；有时指某个动作的人或心里所指的人。Eg: Someone is knocking at the door. Go to see who it is. 有人在敲门。去看看是谁。4)指距离、时间、季节、天气、气候等自然现象、指环境、情况等。Eg: Its sunny today. 今天天气晴朗。Its 10:00 now.现在10点。5)it常用作形式主语句式： It is + 形容词 + for sb./ of sb. to do sth.Eg: It is important for us to learn
5、English. 对我们来说学英语很重要。It is kind of you to help me. 你能帮我真善良。注意： 形容词如果形容人的品格则用of；否则用for6)it常用作形式宾语Eg: He found it difficult to learn maths. 他发现学数学很难。(二)物主代词* 含义：物主代词就是人称代词的属格，表示“所有”。因此，物主代词和人称代词是相对应的。Eg: I always do my homework after dinner.我总是晚饭后做我的作业。如同名词所有格和of属格一样，物主代词也有形容词性和名词性物主代词之分。Eg: This is m

9、（强调所有照片中的一张）(三)反身代词* 含义：反身代词是一种表示反射或强调的代词。基本含义为：通过反身代词指代主语，使施动者把动作在形式上反射到施动者自己。因此，反身代词与它所指代的名词或代词形成互指关系，在人称、数上保持一致。Eg: He saw himself in the mirror. 他在镜中里看见了他自己。 (himself 和he为同一人)He saw him in the mirror. 他在镜子里看见了他。 (him指另一个人)* 形式单数复数第一人称Myself我自己Ourselves 我们自己第二人称yourself你自己Yourselves 你们自己第三人称Himse
