新概念英语第一册第127-128课课文重难点 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。

　　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。
