6.So far the boys have be able to swim across the river.be改为been.分析 到目前为止,这些男孩子已经能够游过河了.
解答 答案:be 改为 been.考察现在完成时 的谓语动词.根据时间状语So far 可知谓语动词用现在完成时have done,所以 be 改为 been.
点评 考查句子改错.
现在完成时的用法:
(1)强调动作是从过去持续到现在,并有可能继续持续下去.
(2)强调对现在的影响或结果,此用法容易和一般过去时混淆.两者的区别是:一般过去时有动作发生的时间点,即过去某一时间发生某一动作;现在完成时则没有,即不强调是哪个时间点发生的动作,而强调过去的动作对现在造成的影响和结果.
(3)在过去不确定的时间里发生的动作,但是结果对现在有影响.
