Question

4．自從來到無錫，我們學校的外教已經習慣了這里的生活．
The foreign teacher in our schoolhas been used to livinghere since he came to Wuxi．

Answer 1

分析 has been used to living．

解答 答案：has been used to living．結合從句since he came to Wuxi表示自從來到無錫，也就是習慣這個動作發(fā)生在過去，一直持續(xù)到現(xiàn)在，故主句用現(xiàn)在完成時have/has+過去分詞，表示習慣于…用be used to doing sth，主語是teacher三單，故has，be的過去分詞been，居住live的動名詞living，故答案是has been used to living．

點評 used to do 過去常常做某事 
be used to doing 習慣于做某事 be used to do sth被用來做某事
