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

答案和解析
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
