(指近处) That is a banana tree. (指远处 ) (2) 指示代词在指事物时有单数、复数之分。 this 和 that 用来表示单数概念 , 系动词 be 用 is 。 there 或 those 用来表示复数概念 , 系动词 be 用 are 。 (3) 当含有 this 或 that 的特殊问句指人时,其回答仍 可以用 this 或 that; 但不指人时,单数用 it, 复数用 they 回答。例: ①Who’s that? That’s Andy Liu.. What’s this? It’s an insect. ② What are those? They are apples.③ 。(4) 在介绍人时,我们常用 this 指下面要提到的人, 而不用其它指示代词。 eg: Ladies and gentlemen, this is Dr Ray, she is going to give us a talk on trees. (5) 打电话时通常用 this 表示自己, that 表示对方, 而不用代词 I 和 you 。 eg: ----Hello, is that Mary speaking? ----Yes, this is Mary speaking. Who is that?3. 叙述在一起的两样东西时,先说的用 this ,后说 的用 that . 如: This is a computer. That is a TV set.5. 最后提醒同学们注意: this 和 is 不能缩写,但 that 、 it 与 is 连用时可分别写为 that's 和 it's 如:This is a dinosaur. (不可写成 :This's a dinosaur. )It is a postcard. (可以写成: It's a postcard. ) 4. 我们平...
