课文详注 Further notes on the text

1．I thought so.我也这样想。

so 是代词，意为“这样”、“如此”。 I think so的否定式为I don't think so（我不这样认为）。类似用so的短句如：

I hope so.

我希望如此。

I expect so.

我期待如此。

I told you so.

我这么告诉过你的。

2．have another look,再（仔细）看一眼。

3． look old,看上去老。

这里look是系动词，后跟表语。

4．at least,至少。

5．I'm sure she is.我肯定她有40岁了。

其后省略了 at least forty。

6．not more than twenty-nine myself,我自己还没29岁。

其中not more than是“不超过”、“不到”的意思。这里反身代词myself是I的同位语，用来加强语气。

She did it herself.

这事是她自己做的。

语法 Grammar in use

表示猜测和推断的情态助动词must和can't（1）

表示最有力的推论的最常用的形式是must和can't。这时，它们一般与系动词be连用。肯定的推断用 must be来表示，否定的推断用 can't be来表示，而不用mustn't。请看例句：

He can't be a doctor. He must be a dentist.

他不会是个医生。他一定是位牙医。

She can't be Danish. She must be Norwegian.

她不会是丹麦人。她一定是挪威人。

He can't be shaving. He must be having a bath.

他不可能在剃胡子。他一定是在洗澡。

It can't be cheap. It must be expensive.

它不会便宜。一定价格昂贵。

He can't be ill. He must be tired.

他不可能生病了。他肯定是累了。
