请看下面这道高考题： —I was riding along the street and all of a sudden, a car cut in and knocked me down. —You can never be _________________ careful in the street. A.much B.very C.so D.too 分析：该题考查的是“cannot (never)… too…”结构的用法。答案为D，句意为“在街上骑车，你越小心越好”。 “cannot … too…”结构表示“无论怎么……也不算过分”、“越……越好”、“要格外……”的意思。表示此意的结构有下列几种： 1.cannot +动词+too +形容词或副词。如： We cannot be too careful in doing experiments. 我们做实验时越仔细越好。 I cannot thank you too much. 我怎么感谢你也不过分。 2.cannot + over动词/cannot + be +over-形容词。如： We cannot overemphasize the importance of learning a foreign language. 我们无论怎么强调学习外语的重要性也不过分。 We cannot be over- vigilant. 我们应该特别警惕。 3.cannot+动词+too much （much enough）。如： We cannot praise him too much. 我们无论怎样表扬他也不算过分。 He is very reliable. You can’t trust him too much (much enough). 他很可靠，他是你最值得信赖的人。 4.cannot +动词+形容词或副词+enough。 在“cannot… too…”结构中的too可换成enough; not也可换成never, hardly等否定词。如： You can never be strong enough. 强壮的身体有百利无一害。 Drinking water can never be pure enough. 饮用水越纯越好。 5.cannot +动词+too many +可数名词（或too much +不可数名词）。如： I think it right that one cannot learn too much knowledge. 我认为一个人的知识越多越好。 It is wrong to think that one cannot bear too many children. 认为一个人生的孩子愈多愈好是错误的。 |
