It is __________ (possible) for him to finish the work in such a short time. He needs more time.
题目考点:形容词的适当形式,表示可能性
答案:
impossible
解析:
根据句意,‘It is __________ for him to finish the work in such a short time’表示‘他在这么短的时间内完成工作是不可能的’,需要用‘impossible’来表达‘不可能’,即‘It is impossible for him to finish the work in such a short time.’
