It’s not real snow, of course. It’s catkins （飞絮） from willows and poplars （杨树） in spring. For some people, this “snow” is not welcomed. Catkins can trigger allergies （过敏症）, making people’s noses, eyes, and skin uncomfortable. 刷速度 返回目录 22 In spring, the female trees grow lots of flowers. When these flowers finish growing, they produce cotton-like seeds that spread through the air. Luckily, scientists have found many ways to control catkins. Doing “gender change surgery （变性手术）” on willows and poplars is one of them. People cut off the branches of female trees and take the place of them with branches from male trees. This cuts down the number of catkins. However, this way is slow and expensive. A skilled worker can do the “surgery” on less than ten trees a day. It was reported that from 2008 to 2018, only around 1,000 trees were treated in Beijing. 刷速度 返回目录 Scientists in Wuxi, Jiangsu, give the trees special injections （注射） to reduce the number of catkins. These injections make the trees mainly use their energy to grow bigger and get more leaves, not to reproduce and make catkins. Xu Qinming, an expert in Wuxi, said that this method was safe for the trees. However, the trees need to get injections every year to keep the catkin number under control. Other than injections, the trees can take “medicine”. This medicine can be sprayed （喷洒） onto the trees before the catkins form, which can quickly reduce the number of catkins. Still, people need to be careful about how much medicine they use and when they use it, or they might hurt the environment.#6 阅读理解B·语篇导读本文主要介绍了科学家研究出来的减少柳絮和杨絮产生的方法。 刷速度 返回目录 14.What can we infer from Paragraphs 1 and 2?( ) D A.Catkins are hard to see.

( ) A A.Replacing the branches of female trees with those from male trees. B.Planting more male trees. C.Planting more female trees.
