【改错】His son is enough old to go to school. (×)
【解析】enough作副词时,意为“足够地”“充分地”“相当地”“很”等意思,修饰形容词、副词时,必须放在这些词之后,结构为“adj/adv + enough”, 表示“足够…的”。例如:
①Liu Xiang runs fast enough.刘翔跑得足够快了。(修饰副词fast)
②The room is big enough.这个房间足够大了(修饰形容词big)
【改正】本题应该为:His son is old enough to go to school. (√)
他的儿子到上学的年龄了。(年龄足够大,可以上学了)
【知识拓展】除此以外,还要注意enough以下用法:
1. enough做形容词,意为“足够的”,修饰名词时,一般要放在名词之前。(有时可放名词之后,但不必考虑)。例如:
①15 minutes is enough time for you to have a coffee.你喝杯咖啡15分钟足够了。
②I have enough money to pay for the taxi.我有足够的钱付车费。
③Have we got enough sandwiches for lunch?我们午餐的三明治够吃吗?
2.用作代词,意为“足够;充分”。例如:
①Enough is enough.适可而止。(谚语)
②―Would you like another piece of bread?你想再来一块面包吗?
―I have had enough. Thank you very much.我已经喝够了,非常感谢。
【常用句型】
“形容词/副词 +enough +(for +sb. ) +to do”结构:“对某人来说,足够....可以...”。
