题目内容
19.Many scientists believe that robots ______ able to talk like humans in 50years.( )| A. | were | B. | are | C. | will be | D. | have been |
分析 许多科学家认为五十年后机器人能和人类一样进行交谈.
解答 答案:C.
本题考查的是动词的时态,根据题干in 50 years可知这是表示将来时间的时间短语,应该用一般将来时,其结构是will+动词原形,故选C.
点评 一种特定的时态都有其相应的时态标志,寻找其时态标志并加以认真分析可以巧解时态试题.本题中in+时间段是一般将来时的时态标志,同学们在做题时若能充分利用这些时态标志,同时结合句子语境,就可很快选出正确答案.
