题型：不详难度：来源：
His uncle ________ for a week.| A．has arrived here | B．has been here | | C．came here | D．will get here |
|
答案
| B |
解析
试题分析：句意：他的叔叔已经在这儿一周了。句中有for a week表示一段时间，用现在完成时，同时谓语动词要有延续性，故选B
点评：动词的时态是学习英语过程中非常重要的知识。现在完成时表示动词在过去发生对现在造成的影响。现在完成时往往和already,yet,for+一段时间，since+点时间的时间状语连用。一般过去时只表动词在过去发生，一般现在时表示习惯性的动词或是客观真理、事实。 |
