问题 When the engine would not start, the mechanic inspected all the parts to find what was at______.
选项 A、wrong
B、trouble
C、fault
D、difficulty
答案 C
解析 这四个选项中只有fault与at能在一起搭配使用。at fault意为"有毛病"，如，My memory is at fault．"我记错了。"in trouble"处于困境(苦恼，不幸)"；wrong"出毛病"，如用wrong，应将at去掉，句子仍成立；difficulty"困难"，in difficulty"有困难"。
