This is a photo i took during my trip to japen

题目

This is a photo i took during my trip to japen
这话是新概念上面的意思是：这是我到日本旅行时拍的照片.那个TOOK不是take的过去式吗,在这句话为什么要有它呢?
i shaved it off when i came home.意思是我回到家就把它（胡子）刮掉了.请问 when干嘛会出现呢,
那是不是在这里 TOOK 就是表示去的意思呢

答案

1、This is a photo (which) I took during my trip to Japan.take a photo照张相这个是定语从句.which指的是photo,因此用take.2、I shaved it off when I came home.这里的when是“当...的时候”....
