走出do的误区

在动词家族中, do 虽是一个不起眼的小不点,但它的作用可大了,忽略了它便会受到惩罚｡同学们可千万别走入 do 的误区哟!

[误区一] 多用 do 或其相应的变化形式

1. 当句子中的谓语动词含有 be 的相应形式(如 am， is， are)时,应在其后直接加上 not 构成否定句,或将 be 的相应形式(如 am， is， are)移到句首构成疑问句,不可再用 do｡例如:

乔治没在和他的朋友玩｡

误:George doesn’t is playing with his friends.

正:George isn’t playing with his friends.

你是澳大利亚人吗?

误:Do you are from Australia?

正:Are you from Australia?

正:Do you come from Australia?

2. 当句子中的谓语动词含有 can, may, must 等情态动词时,应在其后直接加 not 构成否定句,或将情态动词移到句首构成疑问句,不可用 do 或它的相应的变化形式｡例如:

吉姆不会说汉语｡

误:Jim doesn’t can speak Chinese.

正:Jim can’t speak Chinese.

我现在可以玩电脑游戏吗?

误:Do I may play the computer games now?

正:May I play the computer games now?

误:Zhang Jun does never stop doing morning exercises.

正:Zhang Jun never stops doing morning exercises.

[误区二] 漏用 do 或其相应的变化形式

1. 在一般现在时态的句子中,当句子的谓语动词是行为动词时,应用 do 或其变化形式构成疑问句和否定句｡例如:

彼得没有留长发｡

误:Peter isn’t have long hair.

正:Peter doesn’t have long hair.

刘芳不喜欢说笑话｡

误:Liu Fang isn’t love to tell jokes.
