根据句意，写出括号内所给单词的适当形式。
【小题1】My father will go to Beijing on business at the beginning (begin) of next month.
【小题2】I couldn’t fall asleep (sleep) because I drank too much coffee in the daytime.
【小题3】Who do you think did worst (badly) in this competition, John, Jim or Jane?
【小题4】--- Is the fruit salad finished (finish)? --- You’d better wait for five more minutes.

解析：【小题1】句意：我爸爸将在下个月初去北京出差。At the beginning of在…开始时，是一个固定短语，所以填写beginning。【小题2】句意：我睡不着因为我在白天喝了太多咖啡。Fall asleep入睡，睡着，所以填写asleep。【小题3】句意：你认为在这场比赛中谁做的最差，约翰，吉姆还是简？由John, Jim or Jane 可知用最高级形式，此处是副词的最高级，故可以省略the，所以填写worst。 【小题4】句意：水果沙拉做好了吗？——你最好再等五分钟。根据句意此处用被动语态，前面已经有了助动词is，所以填写过去分词finished。

我也是这个答案
