I saw her last week中last week 是constituents of phrase 还是 constituents of sentence 为什么?谢谢

【专家解说】：恩恩，last week 不是短语啊，是时间状语，像什么today,the before yesterday....... 短语要平时多积累一下，就分清楚了，在做题时要思考一下总接一下，很快就可以分清了，因为他们有共性的 像短语come up with，pay attention to......凭我个人经验，我告诉你啊，短语一般由动词和介词组成,move away i don't like to go to school,so everyday I want to escape from the school like to, go to school,want to ,escape from，这些包含了动词和介词的都是短语，恩，我教你了，你在平时做题时要多留意，多总结，就很快区分了
