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
时态题。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继续延续下去的动作。“since+时间点”常用于完成时,表示某事于过去某一时间开始,并且现在仍在继续。因此,has been maintaining “一直在维持”为答案。A项maintains “维持”是用于一般现在时的动词的第三人称单数形式;B项is maintaining“正在维持”是现在进行时的用法;C项maintained“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。
