Unit 3

1. This is his sister. 这是他的妹妹。

向一个人介绍另一个人, 用This is…。例如:

This is my mother. 这是我的妈妈。

This is Gina. 这是吉娜。

【拓展】

This is…的其他用法:

(1)用于指空间上较近的事物。例如:

This is a car. 这是一辆小轿车。

This is Lilys bag. 这是莉莉的书包。

(2)用于电话用语,意为“我是……”。例如:

“Who is that?” “This is Tom speaking.” “你是谁?” “我是汤姆。”

2. And thats my sister. 那是我妹妹。

(1)and用于此句表示承接关系,起连接的作用。不用翻译。

(2)句中thats是that is的缩写形式。意为“那是”。此句式常用于介绍离其较远的人或物。例如:

That is a desk. 那是一张桌子。

Thats his brother. 那是他的哥哥。

3. Is that your brother? 那是你哥哥吗?

Is that…是由that is构成的一般疑问句,意思是“那是……吗?”是用来辨认人或物的。指人时,常指不明确其性别。回答时用:Yes, it is./No, it isnt. 例如:

“Is that Mr Wang?” “Yes, it is.” “那是王老师吗?” “是的,他是。”

“Is that your computer?” “No, it isnt.” “那是你的电脑吗?” “不,它不是。”

【拓展】

此类询问人的一般疑问句还有:Is she…? Is he…?。回答时用:Yes, she is./No, she isnt.和Yes, he is./No, he isnt. 例如:

“Is he your friend?” “Yes, he is.” “他是你的朋友吗?” “是的,他是。”

“Is she your aunt?” “No, she isnt.” “她是你的姑姑吗?” “不,她不是。”

4. Thanks for the photo of your family. 谢谢你们家的照片。

“Thanks for…”为某事而感谢,for是介词,表示原因,后面接名词或者动词的-ing形式。这里的thanks为名词形式。例如:

Thanks for your help. 谢谢你的帮忙。

Thanks for helping me. 谢谢能够帮助我。

【拓展】

“thank”还可作动词,意为“感谢”。thank sb. for sth./doing sth.意为“感谢某人做某事”。后可直接接名词或接动词的-ing形式。例如:

Thank you for your help. 谢谢你的帮助。

Thank you for inviting me to your birthday party. 谢谢你邀请我参加你的生日聚会。

5. Here is my family photo!这是我的全家福!

Here is…是倒装句型,其正常语序为My family photo is here.。在英语中,here, there置于句首起强调作用。其基本结构为:Here/There+be/其他动词+名词或名词短语。当主语为代词时,常用不完全倒装形式:Here/There+主语(人称代词)+be动词等。be的单复数取决于后面主语的单复数。例如:

Here she comes. 她来了。
