有些英语疑问,
He used to go fishing (这句话没有错吧),He is used to Beijing food(这句话也没错哈)
1.为什么前者加了BE动词,而后者没有加?麻烦讲下什么时候可以加,什么时候不用加.
These children have been studying English for 3 years.-- He has learned English since he came to our school
1.都是完成时,为什么前者要用have+been+dong 的结构,而后者要用has+learned?
2.可以把前者改成These children have learned English for 3 years?可以把后者改成He has been learnning Englishi since he came to our school?
3.,什么时候要用have+been+dong 的结构,什么时候要用类似has+learned的结构?该怎么用 .

额.这些问题.不是刚才.
再问：不知道怎么的，被百度删了！！！还没有看
再答：啊！！！我辛辛苦苦打的字啊！！还有哪里不明白吗？
再问：其实我还没有看完！就那个used to 那几个句型比如be used to do 是。。。。什么意思，好像有三个！老师，可以留下你QQ吗？谢谢，以后有不懂可以问你
再答：。。
