问题补充:
Two weeks ago, I bought a bicycle. If you live in town, it is often faster than a car and you worry about parking.
A. must not
B. should not
C. don have to
D. may not
答案:
A. must not
B. should not
(答案→)C. don have to
D. may not
解析:考察情态动词用法。Must not禁止,千万不能;should not不应该;don have to不必;may not也许不;句意:两个星期前,我买了一辆自行车。如果你住在城里,自行车经常比汽车还有快,而且你不必担心停车的问题。根据句意说明使用C项。
