Step 1 ~ Text ~

JEAN: Where's Sally, Jack?


JACK: She's in the garden, Jean.


JEAN: What's she doing?


JACK: She's sitting under the tree.


JEAN: Is Tim in the garden, too?


JACK: Yes, he is. He's climbing the tree.


JEAN: I beg your pardon? Who's climbing the tree?


JACK: Tim is.


JEAN: What about the dog?


JACK: The dog's in the garden, too. It's running across the grass. It's running after a cat.


Step 2 ~ Notes on the text ~

Where's = Where is。

She's sitting under the tree. 她正在树阴下坐着。

句中is sitting是现在进行时结构,这里是表示现在正在进行的动作。

What about the dog? 那么狗呢?

这句话的意思是:What is the dog doing in the garden? 为了避免重复原句中的主语和谓语动词可以用What about ...? 这个结构,用来询问情况。What about ...?(……怎么样?)是英语口语中较常用的一个句式,也可以说How about ... ? about一词后面可跟人,也可跟物。通常在对话中,有上下文情况时使用,用于询问情况或征求别人意见。

run across 跑着穿过


200000 — two hundred thousand

1000000 — one million

Step 3 ~ Grammar in use ~


 在英文中若想表达此刻正在进行的动作或事件,要用动词的现在进行时形式。现在进行时由be的现在时形式(am, is, are)+ 现在分词组成。如课文中的She's sitting under the tree. 和He's climbing the tree. 等句子均为现在进行时。对大多数动词来说,在动词后面直接加-ing即可构成现在分词,如doing,climbing。以-e结尾的动词,要去掉-e,再加-ing,如making。如果动词只有一个元音字母而其后跟了一个辅音字母时,则需将辅音字母双写,再加-ing,如running,sitting。
