4、 night,which is very interesting.我昨天晚上读了一本小说,它非常有趣。(2)作用不同限制性定语从句可以修饰名词或代词,与先行词关系密切，若去掉,则句意不完整。非限制性定语从句可以 修饰名词或代词,也可以修饰整个主句或主句中的一部分,对先行词仅起补充说明作用,若去掉,句意仍相对完整。Do you remember the man who taught us English?你记得教我们英语的那个人吗?A trip to Rome can be pricey for travellers,which is why many choose to stay in a h
