这一课里,涉及到一个非常重要的词的用法——助动词。很多同学学到这里会晕,问题往往出在不知道什么时候使用 be 动词,什么时候使用助动词上面。

我们观察这节课课文中的句子,都是这样的句型:

do you +?动词原形.....

christine : do youlike coffee, ann?

christine : do youwant a cup?

christine: do youwant any sugar?

christine: do you want any milk?

christine: do youlike biscuits?

christine: do youwant one?

句子中的这个 do 有一个称呼,叫“助动词”。

背诵下面的概念:

助动词的意思,就是这个词(do)要帮助句子中的动词提问和否定。只有没有使用 be 动词和情态动词的句子,才需要用到助动词。

我们来展开讲一下上面要求大家背诵的概念。

只有没有使用 be 动词和情态动词的句子,才需要用到助动词。

有be动词的句子,为什么不需要用到助动词呢?因为 be 动词本身就能完成提问和否定的功能,并不需要别的词帮忙。

例如:

it is hot today.

在第一课中就学了,我们把这个句子变成疑问句,只需要把 be 动词提前:

is it hot

today?

把这个句子变成否定句,只需要在 be 动词后面加 not:

it is not hot today/ it isn’t hot today.

既然, be 动词已经足以提问和否定了,就不需要再用别的词了。所以,有be 动词的句子,不需要用到助动词(现阶段)。

情态动词同理,本身就足以完成提问和否定。

例如:

i can swim.

can you swim?

i cannot swim.

i must see her.

must you see her?

i?mustn’t see her.

再来重复一遍,只有没有使用 be 动词和情态动词的句子,才需要用到助动词。

对于没有be 动词的句子,提问和否定就都需要借助助动词了。

比如:

i like coffee.

这个句子里没有 be 动词。那么你要提问的时候,就不能像有 be 动词的句子一样,直接把动词提前,变成:

like i coffee? ?

必须要借助助动词,让助动词在句首:

do you like?coffee? ??

在否定的时候,也不能像有有 be 动词的句子一样,直接在动词后面加 not,变成:

i like not coffee.??

必须要借助助动词+not,放在动词前面:

i don’t like coffee.???

所以文章中的这几个问句,我们都可以还原为陈述句:

i?want?a cup.

i?want?some sugar.

i?want some?milk.

i?like?biscuits.

i?want?one.

对于使用了助动词的提问,通常回答的时候也是用助动词。

比如:do you like coffee?

通常不回答:

yes,i like coffee.

而是沿用助动词:

yes, i do.

因为通过上文我们已经知道在谈论什么了,再使用完整的回答太啰嗦了。


lesson 48?do you like .. .?你喜欢.....吗??do you want.. .?你想要.....吗?

根据图片中的内容,使用 do you like .... 和 do you want ....句式问题并回答。

例如:

do you want any eggs?

yes, i do.

a. ?完成以下句子,用off, over, between, along, in front of, behind, under 或 across 等介词或介词短语填空。

1 the aeroplane is flying _____ the village.

2 the ship is going?_____ the bridge.

3 the children are swimming _____?the river.

4 two cats are running _____?the wall.

5 the boy is jumping _____?the branch.

6 the girl is sitting _____?her mother and her father.

7 the teacher is standing _____?the blackboard.

8 the blackboard is _____?the teacher.

b.?模仿例句回答问题,注意可数名词与不可数名词的区别

例子:

do you like eggs?

yes, i do. but i don’t?want one.

do you like butter?

yes, i do. but i don’t want any.

1 do you like honey?

2 do you like bananas?
