Christmas Day was coming.Father and Son went to get a Christmas tree.请问第一句的时态?
是不是过去进行时?第二句的句子成分都是什么?go to后接的是不是从句?
I was surprised to learn that he was taking drugs.这句中surprise是及物动词还是不及物动词？后面接to应该是不及物吧？这句They were surprised to find the animals at their gate.这句的用法也是接to接doing。能否把句子成分分析一下呢？是不是主系表结构+to do+从句

Answer 1

1 Christmas Day was coming 过去将来时（进行时中动词如果是瞬间动词可以用来表示将来）
2 Father and Son went to get a Christmas tree一句中
Father and Son 作主语
went 谓语动词
to get a Christmas tree目的状语
3 go to 后面接的不是从句.从句必须具备有主语,但go to 后面没有.
I was surprised to learn that he was taking drugs.这句中surprise是形容词“惊奇的”,非动词
to learn that he was taking drugs是不定式作原因状语,说的是惊奇的原因；
They were surprised to find the animals at their gate一句中
they是主语
was是系词
surprised是表语
to find the animals at their gate是原因状语
