问题描述:
Now he _____ (wave) his arm towards Bill.
这里用is waving还是waves?
At the moment the taxi stops and the passenger gets off.Now he _____ (wave) his arm towards Bill.It turns out to be Jim,Bill's best friend!
答
您好,如果是单独一句话:
Now he is waving (wave) his arm towards Bill.
这里有 now 进行暗示是现在的动作,所以用现在进行时.
但你给出了上下文:
At the moment the taxi stops and the passenger gets off. Now he waves (wave) his arm towards Bill.It turns out to be Jim,Bill's best friend!
这里很明显要用一般现在时 waves,原因是前后句都在保持这个时态记叙同一个时间段发生的事情.Now在这里的意思是“叙事时发生的时间”,“当时”,不知道你理解了没.
希望对您有帮助,不懂的话可以继续提问.
