Answer 1

1.参考答案为tomorrow morning,如果把morning去掉,你就很自然的知道不用介词了,morning修饰tomorrow的.
2.应该说两个都是不恰当的,因为句中often表示频率,而this表特指.要么把in this afternoon 改为in the afternoon,要么把often去掉,选用 this afternoon
3.参考答案为on foot,是固定搭配.by bus 而不是by a bus,是ride a bike而不是take a bike
4.参考答案为in five days,in 后加一时间段表示多久以后.句子意思是,五天以后我回去看我的祖母.after一般不用在将来时中.
5.next week,解释参见第一题.
