今天我去搜索了六年级上册第二单元的作文预习，里面的内容是这样的：

I am a student . I usually go to school by bike . My home is far from my school . I must pay attention to the traffic lights . I know them very well . Slow down and stop at a yellow light . Stop and wait at a red light . Go at a green light . We must go on the right side of the road in China .

我是一个学生。我通常骑自行车去上学。我家离学校很远。我必须注意红绿灯。我很了解他们。慢下来，在黄灯处停下来。遇到红灯时停下来等待。绿灯时行驶。在中国，我们必须靠右边行驶。
