单选题 John will have to go to work by bus as his car ______.
A. is repaired B. is needed repairs
C. is being repaired D. is needed repairing

【正确答案】 C

【答案解析】该题是语法题，考查动词被动语态的用法。选项A表示修好了。选项B和选项D中动词need的使用不对，应该是needs repairing才对。选项C是动词被动语态的现在进行时，表示“正在被……”，如：The reform is being carried out in China. 中国正在进行改革。因此，根据题意和语法规则，选项C为最佳答案。
