① The “April snow” is here! It’s not real snow, of course—it’s catkins(飞絮) from willows(柳树) and poplar trees(杨树) in spring. The female trees grow lots of flowers. When these flowers finish growing, they produce cotton-like seeds that spread through the air. For some people, this “snow” is not welcomed. Catkins can cause allergies(过敏), making people’s noses, eyes, and skin uncomfortable.
② Luckily, scientists have found many ways to control catkins. Doing “gender change surgery(变性手术)” on willows and poplar trees is one of them. People cut off the branches(树枝) of female trees and replace(替换) 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. From 2008 to 2018, only around 1,000 trees were treated in Beijing, reported *Outlook Weekly* in 2022.
③ Scientists in Wuxi, Jiangsu use special injections(注射剂) to reduce the number of catkins on trees. These injections make the trees mainly use their energy to grow bigger and get more leaves, not to reproduce(繁殖) and make catkins. Xu Qinming, an expert in Wuxi, told *Science and Technology Daily* that this method is safe for the trees. However, the trees need to get injections every year to keep the catkin numbers under control.
④ 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 catkin numbers. Still, people need to be careful about how much of the medicine they use and when they use it, or they might hurt the environment.
⑤ It is sure that with the development of science and technology, there will be more convenient ways to deal with the problem.

答案：9. D
10. D 【解析】根据第二段中“People cut off the branches of female trees and replace them with branches from male trees.”可知,人们砍断雌树的树枝,然后用雄树的树枝来替换它们,这一过程称为“变性手术”。
11. A 【解析】根据第三段中“However, the trees need to get injections every year to keep the catkin numbers under control.”可知,使用特殊的注射剂可以减少飞絮的数量,但这些树每年都要被注射来保证飞絮数量在可控范围内。
12. C 【解析】通读全文可知,第一段总领全文,介绍了飞絮及其危害;第二、三、四段分别讲述了减少飞絮的方法;第五段总结全文,表达了作者对未来能用更便捷的方法来解决这一问题的期待,因此 C 选项符合文章结构。

① “四月雪”来了！当然，这不是真正的雪——它是春天里柳树和杨树的飞絮。雌树会开出很多花。当这些花生长完成后，它们会产生像棉花一样的种子，这些种子会在空气中传播。对一些人来说，这场“雪”并不受欢迎。飞絮会引起过敏，使人的鼻子、眼睛和皮肤感到不适。
② 幸运的是，科学家们已经找到了很多控制飞絮的方法。给柳树和杨树做“变性手术”就是其中一种方法。人们砍掉雌树的树枝，然后用雄树的树枝替换它们。这会减少飞絮的数量。然而，这种方法速度慢且成本高。一名熟练工人一天能给不到十棵树做这种“手术”。据《瞭望周刊》2022年报道，从2008年到2018年，北京只有大约1000棵树接受了这种处理。
③ 江苏无锡的科学家们使用特殊的注射剂来减少树上的飞絮数量。这些注射剂能让树木主要把能量用于长得更粗壮、长出更多叶子，而不是用于繁殖和产生飞絮。无锡的专家徐勤明告诉《科技日报》，这种方法对树木来说是安全的。然而，树木每年都需要注射，以将飞絮数量控制在一定范围内。
④ 除了注射，树木还可以“吃药”。这种药可以在飞絮形成之前喷洒在树上，这样能快速减少飞絮的数量。不过，人们需要注意用药的剂量和时间，否则可能会对环境造成伤害。
⑤ 可以肯定的是，随着科学技术的发展，将会有更便捷的方法来解决这个问题。

A. 树木每年都需要注射。
B. 做这项工作需要很多熟练工人。
