3、I went to see you yesterday evening.But you weren't in.Where were you then?
I _____ a walk by the lake with my husband.
A was having B am having C have had D have

Answer 1

1，楼主打的容易让人误解的说：分两种情况讨论如下：
（1）tomorrow后面不加IF从句的话选D 句子表示将来时WILL表示客观上的，BE GOING TO是主观打算
（2）tomorrow后面是从句那就选A主将从现
2next week表示将来的时间所以选C(BE DOING可以表示将来）
3询问过去某点钟正在做什么应该用过去进行时显然选A
希望对你有帮助

Answer 2

1、Shall we go to Monkey Island for a picnic tomorrow?
If it __A____ fine (if 条件句中所指代的时间是tomorrow，按照主将从线原则，be用is的形式）
A is B was C is going to be D will be

2、I __A___ the Greet wall next week.（一般现在时在口语中可以用于表述将来的动作）
Have a good trip!
A visit B visited C am visiting D have visited

3、I went to see you yesterday evening.But you weren't in.Where were you then?
I ___A__ a walk by the lake with my husband.（针对过去某一时间点发生的动作，用过去进行时）
A was having B am having C have had D have
