2．–Whose cat is that?那只猫是谁的？ -It is her cat./It's hers.是她的（猫）。 （1）whose 疑问代词，意为“谁的”，其后加名词，再加一般疑问句，或whose加一般疑问句。如：
Whose computer is that?= Whose is that computer? 那是谁的电脑？
（2）hers 为名词性物主代词，意为“她的（猫）”，其后不在加名词。 3．I think it's Li Ming's.我认为（想）是李明的。 （1）I think 可作为插入语，通常放在句尾或句首。 如：-What's that? 那是什么？ - A plane, I think.我想是飞机。
（2）当不能简单的用Yes 或No回答的时候，可用I think 来表达。
如：-Can you spell it? 你会拼写（它）吗？-I think so.我想我会。 （3）Li Ming's 是名词所有格，意为“李明的”。 名词所有格一般表示所有或所属关系，意为: “……的，在名词后加上's. 如： Maria's book is here.玛利亚的书在这里。
【拓展】1) 单数名词词尾加's. 复数名词词尾没有s 的，也要加's,表示所有格。 如：the boy's food 男孩的食物 men's room 男厕所 2）名词已有复数（即词尾已有s）,则只加“”，表示所有格。 如：a girls' school 女子学校 Teachers' day
3)如果两个名词并列并且分别有's,则表示分别拥有；如果只是最后一个名词后有's，则表示共有。
如：John's and Mary's room 约翰和玛丽各自的房间。（各有一个房间）John nd Mary's room 约翰和玛丽共同的房间。（共有一个房间）
【链接】前面我们已经学习了加's 的缩写形式。如：he's, what's, that's 等。是所有格还是缩写形式必须根据具体的语境来判断。如： That's a book.那是一本书。（that's 是that is的缩写形式，意为“那是”。） 翻译短语。

4.吉姆和汤姆共有的房间_____________________________________ 5.我妈妈的房间__________________________________________
4.We look the same, but we are in different clothes.我们看起来很像，但我们穿着不同的衣服。
Clothes总以复数形式出现，统称各种衣服，包括上衣、裤子、裙子、帽子和鞋等，不指单件衣服，也不和具体数字的数词连用。它作主语时，谓语用复数。如：My new clothes are from Guangdong. 我的新衣服产自广东。 Don't judge a person by the clothes he wear. 不要以貌取人。 【链接】我们已学过关于服装的名词有：dress女服，连衣裙；cap 帽子；shoes 鞋，coat 外套，大衣；skirt 短裙； shirt(男士)衬衫； T-shirt T恤衫；pants裤子 5.This man is from Canada.这位男子来自加拿大。Man （男人）的复数形式是men; woman(女人)的复数形式是women,注意 women 的读音是/'wimin/.
【拓展】当man, woman 作定语修饰名词时，如果名词是复数，那么man 和 woman也用复数形式。如：men teachers 男教师， women doctors 女医生 6.Please help us find him.请帮我们找到他。 （1）注意此句中动词help的句型。“帮助某人做某事”可以是help sb do sth,也可以是help sb to do sth.或 help sb with sth. 如：She help me (to) learn English.=She helps me with my English.她帮我学英语。 （2）此句中的us, him分别是we,he 的宾格。动词和介词后面的人称代词要用宾格的形式，I can help him.我能帮助他。I go to school with her.我和她去上学。
