Tom used to ______ short and fat, didn’t he ? —Yes, he did. Now he’s tall and thin. A．do B

Tom used to ______ short and fat, didn’t he ? —Yes, he did. Now he’s tall and thin. A．do B

D

试题分析：根据可知此句的含义是Tom以前又爱又胖，表示过去常常做某事用固定句型结构used to do sth，又因short和fat是形容词，其前要用系动词故选D。 点评：注意区分be used to doing sth、used to do sth 、be used as和be used for doing sth四个个句型结构的区别和意义。be used to doing sth是习惯做某事，used to do sth表示过去常常做某事，现在不做了。be used as是把…用作…be used for doing sth表示被用来做某事。
