The window was broken by my brother. 是被我弟弟给打破的。What's broken也是被动结构，be动词过去分词，break, broke, broken. 再看第二种用法，表示时间在什么什么之前不迟于IT needs to be ready by next friday，下周五之前，这个需要准备好表示时间。By the time we got home, we were tired and hungry. 等到我们到家的时候，我们又累又饿的。注意这个词组by the time往往联系在一起，用到什么什么为止。当什么什么的时候到什么什么的时候，by the time等到我们到家的这个时候。第三种用法是通过使用，you can booked the table by phone, 可以用电话来预定位置。Book做动词是预定book the table。They traveled to chicago by train, 是通过是以什么方式？是搭火车旅行，到芝加哥去旅行的，trade to chicago. 这个by train表示一些交通方式，是大家最熟悉的，bike、by bus、by air等等。你像by car、by taxi、by air, 乘飞机还是乘船？By sea通过陆地去还是公路去？By land是by road，by rail就是搭火车去了。By rail铁路by train还可以说是通过做某件事情，by doing something, SHE earns her living by some insurance, earns one's living, 意思是谋生的意思。它还可以换成make SHE makes her living也是谋生。通过doing something selling，通过卖insurance，卖保险insurance，通过做某件事情，通过使用什么？这是第三种用法。第四种用法则是指靠近在旁边。SHE stood by . the window, 她站在窗户旁边stand的过去式，stood . come . and sit by me过来，坐在我身边来sit by me靠近。第五种用法是路过经过。He worked right by me without even saying hano, 他就从我身边路过走过，甚至连招呼都没有打，without even saying hello. 注意这里的saying ING是without介词，介词后面看见动词，我们就一定要记得加ING。I passed by the fun everyday on my way to work. 每天我去上班的路上都会经过这个农场。Die是经过路过的意思。第六种用法表示逐渐的变化，表示某件事物在渐渐的发生。Day by day, he grew weaker. 一天一天的，他变得越来越虚弱，weaker比较级，一天比一天更加的虚弱了。Weaker little . by little, I was beginning to discover the truth. 一点一点的，我开始to discover . the . truth，是发现了真相。第七种用法是抓着物体或者身体的某个部分，也用这个。By he took the old woman by the ARM是抓着他的胳膊，也就是搀扶着这个old woman，let her across the road, that是need的过去式，引导need net net牵着她过的公路。第八种用法用在这个短语当中，all by oneself是独自或者独自一人。Dave spend Christmas all by himself, 他是自己一个人度过的圣诞节。You can move the furniture all by yourself. Furniture是家具，你一个人是搬不动这些家具的。第九种用于运算当中乘以或者是除以。What's forty eight divided by four, 这个by for用到介词，by defied就是除划分的意思。最后它用在一些短语当中，意思是由于出于什么？I met him by chance out working yesterday. 昨天我外出去散步是意外，偶然的遇到了他。By chance就是偶然意外的意思。He took my umbrella by mistake, 他拿我的雨伞是by mistake。怎么样拿的呢？错误的拿的这个by用在这样的短语当中，由于。后面大家把这些buy的一些短语还要再复习巩固一遍。Thank you.
