一、选词填空。（填序号）
1. Hello! We are (A. friends/B. twin).
2. (A. I/B. It) is a cat. Nice to meet you, little cat!
3. This is Mr Zhou. (A. He/B. She) is my English teacher.
4. I'm nice, so I have many friends in (A. I/B. my) class.
5. (A. It's/B. This) is Zhuge Liang. He is very clever(聪明的).
6. Yang Ling, this is Liu Jiajia. (A. She/B. She's) my new friend.

1. A 解析:"We are"表明是复数,"friends"(朋友,复数形式)符合,"twin"(双胞胎之一)是单数。故选A。
易错提醒
名词单复数
易错点在于名词单复数及twin词义辨析不清。friends是复数形式,twin指双胞胎之一,是单数,根据be动词"are"可知,这里应选friends。学生在英语学习中要注意对单词词义的理解。
2. B 解析:It后be动词用is,I后be动词用am,空后是is。故选B。
3. A 解析:"Mr Zhou"是男性,用"He"指代,"She"指代女性。故选A。
4. B 解析:这里需要修饰名词class,所以要用形容词性物主代词my(我的)。I是主格代词,只能作主语,不能直接修饰名词。故选B。
知识点拨
I和my的辨析
一、意思不同
I:我;my:我的
二、用法不同
1. I是主格,放在句子开头,作主语,后面直接跟动词。
例:I am a student. 我是一名学生。
2. my是形容词性物主代词,后面必须跟名词,表示"我的……"。
例:This is my book. 这是我的书。
三、一句话口诀
I是我,放句首,后面动词跟着走;
my是我的,后面加名词,不能单独用。
5. B 解析:"This is ..."用于介绍某人,"It's"是"It is"的缩写,意为"它是",这里介绍人用"This is"。故选B。
6. B 解析:"She's"是"She is"的缩写,意为"她是","She"只是"她",这里表达"她是我的新朋友"用"She's"。故选B。

二、根据对话，选择相应的图片。
A. B. C. D.
()1. —Good morning, Sam. —Good morning.
()2. —It's good. —Thank you.
()3. —What's your name? —My name is Zhang Hua.
()4. —Su Yang, this is Wang Bing. He's my friend. —Nice to meet you.

1. C 2. D 3. B 4. A
