这可绝不是件容易的事。一年，二年，至少有三四年；一滴汗，两滴汗，不知道多少万滴汗，才挣出那辆车。从风里雨里的咬牙，从饭里茶里的自苦，才赚出那辆车。那辆车是他的一切挣扎与困苦的总结果与报酬，象身经百战的武士的一颗徽章。在他赁人家的车的时候，他从早到晚，由东到西，由南到北，象被人家抽着转的陀螺；他没有自己。可是在这种旋转之中，他的眼并没有花，心并没有乱，他老想着远远的一辆车，可以使他自由，独立，象自己的手脚的那么一辆车。有了自己的车，他可以不再受拴车的人们的气，也无须敷衍别人；有自己的力气与洋车，睁开眼就可以有饭吃。

    Last December, students at Duluth Edison Charter school in the US took part in a food drive. They were on their way to collecting food and other things for their local food bank.

    Since lots of people in the world are still suffering from hunger, food banks are set up to help them. They collect and store food and give it to people who cannot afford to buy it. There are thousands of food banks in the world. Some people donate(捐赠) food or money to them, and some work as volunteers in the banks. The students from Duluth Edison Charter School had their own task—they had to collect what poor people needed for their holiday.

    Each grade received different requests(需求) from the food bank. Some needed to collect potatoes and vegetables from the farm. Some went to bakeries(面包房)to ask for cakes. And for seventh grade donating is simple. "Not everybody has everything they need, and we think it will be nice to give everybody what they need for the holiday," said Sydow.

    Students collected a total of 1,409 items for the food bank and donated ＄262. "Thanks for your help," said Eric, the leader of the local food bank. "The poor people will have a nice Christmas just like everybody else."
