学生问:be used to do和be used to doing有什么区别?
第一,used有两层含义,use作为动词,be used是被动结构,to do是分词;used是形容词,be used to表示习惯做某事,doing是分词。一句话说清表达:
1.Peppers are used to make spicy food.
2.I used not to eat spicy food before, but I am used to spicy food now.
3.I used not to eat spicy food before, but I am used to eating spicy food now.
第二,在Tyger的语法体系中,used to do中used to归于情态助词,used区分动词或形容词,动词后分词选to do,形容词后分词选doing。
第三,不论中考还是高考,used都是一个较难的内容,突破点仍然是结构。
