A．not B．not a C．no D．not some 答案选择 C，no 置于可数名词单数前面时，相当于 not a；放在可数名词复数前面或不可数名词前时，相当于 not any，意为“没有的，全无的”。因此答案选择C。 4、as far as的用法 ① 我们走得不如其他人远。 We didn't go as far as the others. ② 就我所知，他人不错。 As far as I know，he's_a good man. ① as far as本义，意为“与……一样远”，“一直到……” (在否定句中也可用 so far as)。 ② 用于引申义，意为“就……而言”，“从……来看”，“尽……所能”，“只要”(有时可用 so far as)。
