翻译题 64.It's said that they have swum to the island from the continent, but they ______(不可能做到)because the ocean in between is too wide.(do)
【正确答案】can’t/couldn’t have done it/that/this
【答案解析】这里表示对已经发生的动作进行推理判断,用can’t/couldn’t have done sth.,由于do是及物动词,这里要加上代词it,that,this,指代前面提到的情况。句意:据说,他们从大陆游到了那座岛屿,但是岛屿与大陆之间的距离太远了,他们是不可能做到这一点的。
