语法点金 小金鹿(上)
作者: 徐小红
阳光洒满树林和草地,一只活泼又健壮的小金鹿正在山谷里蹦蹦跳跳。凉爽的山风吹来,亲吻他的脸颊,把他的歌声送到了山的另一边。
小金鹿:
Be 动词妈妈真伟大,
生了三个胖娃娃:am,is,are。
我(I)用am,你(you)用are;
Is 跟着她(she)、他(he)、它(it);
我们(we)、你们(you)、他们(they)都用are;
单数和不可数名词用is,复数名词全用are。
忽然,小金鹿听见前方山谷里隐约传来一阵呻吟声。他走过去一看,只见芭蕉姐姐低垂着黄色的叶片,满脸苦痛。
小金鹿:How are you? Are you ill?
芭蕉姐姐:I’m thirsty. The dewdrops(露水) are very important. But there isn’tany dewdrop now. I am dying(濒死的).
小金鹿:Look, the sun is setting. Thebirds are backing home. The dewdrops arecoming soon. Come on!
夜渐渐深了…… 一滴露水滴落下来,接着,第二滴、第三滴…… 喝足了露水的芭蕉姐姐渐渐恢复过来。小鹿高兴得又蹦又跳,继续唱那支动听的歌。
小金鹿:
变否定,很容易,be后not 加上去;变疑问,往前提,句末问号别丢弃;否定疑问任你变,句首大写莫迟疑。
听见小金鹿的歌声,别的小动物们都从森林里跑了出来。他们聚集在一起,纷纷讲述起be 动词家族的故事。
小山猴:
1. 主语是单数名词,be 动词用is。如:
My mother is a nurse.
2. 主语是不可数名词,be 动词也用is。如:
Knowledge(知识)is power.
3. 主语是复数名词,be 动词用are。如:
These apples are sweet.
小兔子:
1. 现在进行时,表示正在做某事。如:
They’re singing in the music room.
2. 现在进行时,表示将来的动作。如:
The dewdrops are coming soon.
小松鼠:
1. will be 或be going to 句型,表示将要发生的事情。如:
I will be there in time.
I am going to be a doctor in the future.
2. Don’t+be 句型。如:
Don’t be sad!
Don’t be late again.
小羚羊:
在一般现在时、现在进行时和be going to句型中——
1. 肯定句改成否定句,在be 动词后面加not 就可以(am not 没有缩略形式,is not = isn’t, are not =aren’t)。如:
I’m not Mike.
They’re not swimming in the river.
She’s not going to Beijing.
2. 肯定句改成疑问句,把be动词移至句首,注意人称的变化,句号变问号就可以了。如:
I’m Lucy.
→ Are you Lucy?
We’re dancing in the park.
→ Are you dancing in the park?
