課文詳注 Further notes on the text
1．I thought so.我也這樣想。
so 是代詞，意為“這樣”、“如此”。 I think so的否定式為I don't think so（我不這樣認(rèn)為）。類似用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.
我這么告訴過你的。
2．have another look,再（仔細(xì)）看一眼。
3． look old,看上去老。
這里look是系動詞，后跟表語。
4．a(chǎn)t least,至少。
5．I'm sure she is.我肯定她有40歲了。
其后省略了 at least forty。
6．not more than twenty-nine myself,我自己還沒29歲。
其中not more than是“不超過”、“不到”的意思。這里反身代詞myself是I的同位語，用來加強語氣。
She did it herself.
這事是她自己做的。
語法 Grammar in use
表示猜測和推斷的情態(tài)助動詞must和can't（1）
表示有力的推論的常用的形式是must和can't。這時，它們一般與系動詞be連用?？隙ǖ耐茢嘤?must be來表示，否定的推斷用 can't be來表示，而不用mustn't。請看例句：
He can't be a doctor. He must be a dentist.
他不會是個醫(yī)生。他一定是位牙醫(yī)。
She can't be Danish. She must be Norwegian.
她不會是丹麥人。她一定是挪威人。
