U.S. News ______ rankings of colleges since 1983. They are a very popular resource for students looking to apply to a university campus.
选项
A、maintains
B、is maintaining
C、maintained
D、has been maintaining
答案
D
解析
现在完成进行时表示一个从过去某时开始发生,一直延续到现在并可能延续下去的动作。“since+时间点”常与完成时连用,表示某事于过去某一时间开始,并且现在仍在继续。因此D项has been maintaining“一直在维持”为答案。A项“维持”,是一般现在时的第三人称单数形式;B项“正在维持”,是现在进行时的用法;C项“曾维持”,是一般过去时的用法。根据完成时的标志词“since+时间点”,排除A、B和C。
