二、几种易混时态的辨析 1．
一般现在时与现在进行时
一般现在时表示经常性的、习惯性的或状态性的行为。 而现在进
行时则具有进行性、未完成性和暂时性的特点。如：
On the wall hangs a picture painted by Qi Baishi. This is not my coat. Mine is hanging behind the door.
如：
[2010·重庆卷] The palace caught fire three times in the last century，
and little of the original building ________ now.
A．remains B．is remained C．is remaining D．has been remained
【解析】 A 考查动词用法及时态。remain作不及物动词用，表
示“剩下，仍有”，只能用于主动语态，不可直接跟宾语。结合语境应用一般现在时表示现状。

一般过去时和现在完成时
一般过去时所表达的事件与现在无关。而现在完成时则强调对现
在的影响和结果。如：
I stayed in Beijing for five days. Then I went to America. (I am not in
Beijing now. )
I have stayed in Beijing for five days and haven't decided where to go
next. (I am still in Beijing now and don't know where to go next.) [2010·北京卷] —I'm sorry，but I don't quite follow you. Did you say you wanted to return on September 20?
—Sorry，I ________myself clear. We want to return on October 20. A．hadn't made B．wouldn't make C．don't make D．haven't made
【解析】 D 本题考查时态和情景交际。答句句意为：抱歉，我
还没有把我的意思表达明白，强调对现在造成的影响，用现在完成时态。
