1.-are tom and jack still in shanghai?
-no.they _have went_(go) back to the united states.They _had stayed__(stay) there for two weeks
第一空如果直接用过去时,后面要有时间状语.这个回答表示,他们已经回美国了,要用现在完成时.第二空,是表示过去的过去,要用过去完成时.
2.mother was so angry with jack when she found he _was smoking_(smoke) in his room.
如果用smoking,那原句要改成found him,him是宾语,smoking现在分词短语作宾语补足语.
但原句中,found 后面是he,所以这里是宾语从句,省略了that,因此要用was smoking
