[-A35] ------ that I would travel to Europe.

翻译：我突然想起来要去欧洲旅行.
解释：
1. 这是occur的一个固定句型.
句型如下：it occur to sb + to do sth 或 that从句,意思是“某人突然想起要做某事”,或“...的想法/念头突然闪现在某人脑海中”.
即此句答案为：It occurred to me that I would travel to Europe.
= It occurred to me to travel to Europe.
2. 该句型中,it为句子的形式主语,而that从句（或不定式短语to do sth）才是句子的真正主语.
英语语法中,只有it才能做句子的形式主语,that不可以,排除C.
3. occur是不及物动词,不能直接加宾语me,必须加上介宾to me,排除A；
而strike也有此种结构,但是strike是及物动词,其句型是：it strike me that从句,排除B（struck是strike的过去式）.
