    it,this 和that都是指示代词,但是它们使用的条件却有很大的区别,而且这三个词都有一些固定的用法,具体说区分如下:

    一、 距离说话人近的人或物用this,距离说话人远的人或物用that。如:

    This is an apple tree. (近处)这是一棵苹果树。

    That is an orange tree.(远处)那是一棵桔子树。

    二、放在一起的两样东西,先说this,后说that。如:

    This is a pen. That is a pencil.这是一枝钢笔,那是一枝铅笔。

    三、向别人介绍某人时说“This is …” 不用“That is …”。 如:

    This is Tom. Tom,this is Jack 1. 这是汤姆。汤姆,这是杰克。

    四、This is 不能缩写,而that is 可以缩写成that’s。如:

    This is a bus. That’s a car. 这是一辆公共汽车,那是一辆轿车。

    五、在回答this 或that 做主语的疑问句时,要用it 代替this 或that。如:

    —Is this a book? 这是一本书吗?

    —Yes,it is. 是的,这是本书。

    —What’s that? 那是什么?

    —It’s a kite. 那是个风筝。

    六、打电话时,介绍自己用this,询问对方用that。注意不可用“I am …”或“Are you …”“Who are you?” 等句式。如:

    —Hello!Is that Miss Green? 你好!你是格林小姐吗?

    —Yes. This is Miss Green speaking. Who’s that? 是的,我是格林小姐,你是谁?

    —Oh. This is Mr Brown. 哦,我是布朗先生。

    七、指性别不明的婴儿、身份不明的人或是只闻其声未见其人的时候用it而不用this或that。如:

    —It’s a nice picture. Who’s in it? 这是张好看的照片,上面的人是谁?

    —Me! 是我!

    八、It 常用来代替前文中所提到的东西。如:

    The pen doesn’t work. It’s Lily’s.这枝钢笔坏了,它是莉莉的。



n.插座,千斤顶,男人;v.抬起,提醒,扛举;n.(Jake)杰克
  • I am looking for the headphone jack.我正在找寻头戴式耳机插孔。
  • He lifted the car with a jack to change the flat tyre.他用千斤顶把车顶起来换下瘪轮胎。
