參考答案:1C one's visit to some place，后面是用介词to，
across“在...之间架起”,在某地方架起桥梁用介词across,over指“在...上面”，through“从物体里面穿过”,比如火车穿过隧道
2C happen是不及物动词,不能用于进行式所以A和D排除,sth. happen to sb.表某人发生了某事,是个固定用法,
supposed +that 从句,表猜想,料想,推测
be supposed to do被相信,认为,根据这个我们看题目就知道B选项是错的,题目中没有这个结构
3C what引导的表语从句
no longer what it used to be,指不再是以前的那个样子了,发生了很大变化了,这是个经常用到而且很有用的句子
4D it指代上文提到过的事物，my book在上面没有出现，我查了资料，也看到了一样的例句是填mine，所以我把A改为D
