1. to go (invite sb to do sth, 邀请某人做某事)
2. making (avoid doing sth, 避免做某事)
3. Heated (being heated的缩略形式，表示被动，被加热)

5. Not having done (做某事没有做对)

Answer 3

to go invite sb todo sth
making avoide doing sth避免做
heated 要表达出被动的意思，用过去分词“被加热，金属膨胀”
working 当工作时，是主动的
Not doing，“没做对，我再做一次”

Answer 4

1，to go .invite somebody to do sth ,邀请某人去做。。。
2，making.avoid doing.避免去做。。。
3,Heated.现在分词做条件状语。分词短语逻辑主语为METAL，和HEAT有被动关系
4.working,主句主语和从句动词WORK有主谓关系，用现在分词。
5.Not having done.
