短文改错
I happen to meet some American tourists at gate of the Summer Palace last week. I
greeted them with English and then we began to chat. I got to know they were college
student traveling in China. Most of us were fond of Chinese medicine. They were busy
taking pictures and were surprising at the changes that had taken place in the past few years. After that, we went boat and had a good time. We were exchanged our e-mail
addresses such that we could write to each other in the future. They thanked me again
and again. I was gladly to have a chance to practice my oral English.happen改成happened
网友回答
(答案→)happen改成happened
解析：
【小题1】happen改成happened，因为这篇文章用的是过去时。
【小题2】at后面加the，考查冠词：特指“电影院的门”，用the。
【小题3】With改成in，用英语,用介词in
【小题4】Student改成students，主语是they，后面的名词是复数
【小题5】us改成them，they的宾格是them
【小题6】Surprising一般修饰物，surprised一般修饰人
【小题7】Boat改成boating，词组：go boating
【小题8】去掉were，we和exchange是主动关系
【小题9】such改成so，so that是引导目的状语从句，“为了”
【小题10】gladly改成glad，be动词后面是形容词做表语
