兔子姐姐:你好!我叫吴雷,现在在读六年级。我们家住在广州,老家在武汉。广州的冬天比武汉暖和,因此爷爷奶奶每年都会从武汉来我们这边过冬。今年因为家乡的亲人办喜事,他们就还没来。兔子姐姐你也知道,我们广东的空气还是比较好的,但是武汉在冬天雾霾就比较严重。我们都跟爷爷奶奶说了,雾霾严重的时候一定要戴口罩。奶奶还好,比较配合,但是爷爷就老是忘记,而且他也不怎么喜欢戴 Rabbit sister: Hello! My name is Wu Lei, and I am now in sixth grade. We live in Guangzhou, home in Wuhan. Guangzhou is warmer than Wuhan in winter, so grandparents come to Wuhan from Wuhan every winter. This year because the relatives of their hometown happy event, they have not come. Rabbit sister, you also know that our air in Guangdong is still relatively good, but the haze in Wuhan in the winter is more serious. We all told the grandparents say, must wear a mask when the haze is serious. Grandma okay, more cooperation, but my grandfather always forget, and he does not like how to wear
