14、sb. doing意思是“讓……繼續(xù)”做某事。 e. g. She kept me waiting for half an hour. 她讓我等了半個(gè)小時(shí)。 2）work on后接賓語(yǔ)，是“從事……，搞……”的意思。 e. g.

20、 2）so…that意思是“如此……以致于”之意。 e. g. I ran so fast I got a pain in my legs. 我跑得太快了，以致于我的腿很疼。 比較so和such表示程度的用法。 so用于“so+形容詞/副詞”，“so+形容詞+a(n)+名詞（單數(shù)）”，“so+many/few+名詞（復(fù)數(shù)）”，“so+much/little+名詞（不可數(shù)）”等結(jié)構(gòu)中。 e. g.

22、 用這樣不好的詞是壞的習(xí)慣。 7. He said that he thought more of a people who has one idea and makes it work, than of a person who has a thousand ideas but doesn’t do anything about them. 他說(shuō)他認(rèn)為與其做一個(gè)有一個(gè)個(gè)想法，但對(duì)這些想法置之不理的人，還不如做一個(gè)有一個(gè)想法，就把它付諸實(shí)際的人。 1）work是“起作用”的含意，根據(jù)上下文看，應(yīng)該譯成“付諸實(shí)際”。 2）more…than…是“與其…不

23、如…”之意。 e. g. I think the book seems to be more a grammar than a dictionary. 我認(rèn)為這本書(shū)看來(lái)與其說(shuō)是一本字典，不如說(shuō)是一本語(yǔ)法書(shū)。 當(dāng)然，more…than可以表示“比…更…”之意。 e. g.
