肖舒文的天敌只有一个，体型格外地小，寻找起来非常困难，有一定的季节性，昼伏夜出，行动时，声音很轻。
Xiao Shuwen has only one natural enemy. He is extremely small in size. It's very difficult to find him. He has certain seasonality. He stays up in the daytime and at night. When he moves, his voice is very light.
对了，就是——蚊子。
By the way, it's the mosquito.
今天同学们一定看到了肖舒文同学的假期收获，眼皮上的大包、脸上还有两个（已经消肿了）。
Today, the students must have seen Xiao Shuwen's holiday harvest. There are two bags on the eyelids and two on the face.
昨天夜里一阵围追堵截，可惜没有发现敌人的踪迹。所以，今天的任务就是将此只蚊子俘获，并就地正法！
Last night, there was a round up, but no trace of the enemy was found. So, today's task is to capture this mosquito and get it right!
