Question

Tina isn’t so quiet as she      . She is much more outgoing now.

1. A.
   did
2. B.
   used to
3. C.
   was used to
4. D.
   used to be

Answer 1

D
試題分析：句意：蒂娜不像她過去那樣安靜。她現(xiàn)在外向多了。聯(lián)系前文可知as引導的從句中應為系表結(jié)構(gòu)，選項AC語義不符，選項B缺少系動詞。故選D。
考點：used to用法
點評：used to用法比較固定，be used to sth習慣于某事;used to do sth過去常常做某事.需要注意use還可以作為被動語態(tài)使用，sth be used to do sth某物被用來做某事。
