“...enoughtodo...”进行转换。如：Theboyissocleverthathecananswerthequestioneasily.＝Theboyiscleverenoughtoanswerthequestioneasily.◆当that引导的结果状语从句是否定句时，“so...that...”可以与“too...to...”或“not...enoughtodo...”进行互换。如：Thegirlissoyoungthatshecan'tlookafterherself.＝Thegirlistooyoungtolookafterherself.＝Thegirlisnotoldenoughtolookafterherself.“如此……以至于……”的其他常见表达方式：①so＋adj.＋a/an＋可数名词单数＋that从句②such＋a/an＋adj.＋可数名词单数＋that从句③such＋adj.＋可数名词复数/不可数名词＋that从句④so＋many/much/few/little＋名词＋that从句一、单项填空(
