by now 应用什么时态
Let‘s see if the baseball game has started yet.
Started?It must be clear who ( ) by now.
A:is winning B:wins C:has won D:would win
这题选A:is winning
原句还原是:It must be clear to find out who is winning at the moment(by now)
by now 可用于多种时态,要根据语境具体分析哦.
By now the power of the Roman Empire was on the wane.
到这时,罗马帝国已日益衰败.
By now,putting satellites in orbit is old hat to space scientists.
现在,对航天科学家来说,把卫星送入轨道已不是一桩新鲜事了.
By now she is redoing problems — how do I get characters into a room — dozens and dozens of times.
到目前为止,她正在无数次地重复解决问题,我该怎么把一个个字母填入一个空位.
By now,all good designers and developers realize the importance of usability for their work.现在,比较牛的设计师和开发者都认识到了可用性在他们工作中的重要性.
Oh,and they go to Buckingham Palace to receive medals from the Queen and,by now,more or less accept it as their due.对了,他们还去了白金汉宫接受了女王的勋章,并且直到现在,或多或少地还是人们接受他们的原因.

如对回答满意,
再问: 答案说选D!是答案错了吗
再答: 嗯,可以保证答案是A,这题之前做过。 解析如下: 句意:让我们看看篮球比赛是否已经开始了?开始了?现在一定能看出谁将赢了。B一般现在时,表经常性动作或状态,明显不对;C现在完成时,表动作已经完成,也明显错;D过去将来时,表过去某时间之后要发生的事情,也不对,故选A,现在进行时表将来。
