问题 By the end of this century, the scientists (discover) ______ a cure for the disease.

选项

答案 will have discovered

解析本题考查的是动词时态变化。“by the end of”意为“到……时候为止”，所以在出现"by the end of"的句子中，句子时态应是完成时态，通常是过去完成时或将来完成时。本句表示到将来某一时间为止的动作，所以要用将来完成时。试比较：By the end of last week，I had learnt 5000 words． (到上周为止，我已经学了5000个单词。)
