新概念英語第一冊第127-128課課文重難點 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）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。
