1. Who is this / that?这(那)是谁?(Lesson 17)

　　这是由who引导的特殊疑问句,常用来询问人的姓名或身份。询问他人是谁时,一般不用Who is he / she?因为这样不够礼貌,而要用Who is this / that? 具体来说,询问近距离的人时用Who is this?如果离得较远,要用Who is that?例如:

　　-Look! The boy is coming. Who is that? 看!那个男孩正朝这边走来,他是谁?

　　-That is Jim. My brother.他是吉姆,我弟弟。

　　2. How old is she? 她多大了?(Lesson 17)

　　how old用来询问年龄,当主语是单数第三人称he, she, it 时,谓语动词be用单数第三人称形式is。回答时可用He / She / It / is...后接年龄。例如:

　　-How old is Li Ning? 李宁多大了?

　　-He is eleven. 他十一岁。

　　3. I think she's twelve. 我想她12岁了。(Lesson 17)

　　I think...是"我想……"或"我认 为……"的意思,说话语气比较委婉。例如:

　　I think Miss Gao is a good teacher.我认为高老师是位好老师。

　　I think he's Mr Zhang.我想他是张先生。

　　当表示"我认为……不是"时,应该说I don't think... 例如:

　　I don't think he is very old.我认为他不太老。　

　　4. Is everyone here today?今天大家全到了吗?(Lesson 19)

　　everyone意为"每个人,人人,大家"。当它在句中作主语时,谓语动词用单数形式。例如: Everyone is here. 大家都在这儿。

　　回答时可以用Yes.(都到齐了。)或No, ...isn't here.例如:

　　-Is everyone here today? 今天大家全到了吗?

　　-No, Lin Tao isn't here today.没有,林涛今天没到。

　　5. -Is she at school today?她今天在校吗? -No, she isn't. I think she's at home. 不,她不在,我想她在家里。(Lesson 19)

　　at school表示"在学校""在上学";at home表示"在家"。在at school和at home中的名词school, home前面不加冠词。例如:

　　This boy is six. He isn't at school. 这个男孩6岁了,他没有上学。

　　Is Mr Wang at home?王先生在家吗?
