最近,我们发现在蓝蓝的天空下,密密麻麻地漂浮着白色小粉尘。它们到处飞舞,有时甚至钻入人的眼、耳、鼻、口中,使人感到浑身不舒服,有些人因此过敏。刚开始,我们以为是工业污染,就向环保局打电话要求查处释放小粉尘的厂家。后来我们才知道,它不是什么工业污染,是烟粉虱虫灾。于是成们环保小组在王老师带领下,积极行动起来,对烟粉虱进行了深入的调查研究。 Recently, we found white dust floating densely under the blue sky. They fly around, and sometimes even into people's eyes, ears, nose, mouth, make people feel uncomfortable, some people are allergic. At first, we thought it was industrial pollution, we called Environmental Protection Agency to investigate and deal with the release of small dust manufacturers. Later we did not know that it is not what industrial pollution is bugworm pest. Under the leadership of the teacher Wang, the environmental protection groups of the two groups took active actions to conduct an in-depth investigation and study on the whitefly.
