📖 題組：
Sometimes when the rain falls hard and fast on you, it might hurt a little. But what happens when it hits a mosquito? A 2012 study says when a raindrop falls on a mosquito, it’s like when a bus hits a person. Besides, the little insect is hit by a raindrop about once every 20 seconds. So why don’t we see many dead mosquitoes after it rains? A mosquito is as big as a raindrop, but it is much lighter—0.002 g only. This saves its life in raindrop attacks. Because the mosquito is so light, when it is hit by a raindrop, it won’t experience a force that is strong enough to kill it. The study also found that when a mosquito is hit by a raindrop, the insect is pushed by the raindrop and falls together with it. But the mosquito doesn’t get wet easily because it is covered with hairs which keep off water. After dropping about 6 cm, it will roll off the raindrop and fly away. However, this trick isn’t always successful. If the mosquito flies too low when it is hit by the raindrop, it won’t have time to fly off. Then it will hit the ground and meet its death.

請讀一下文章的第二段，作者提到蚊子和雨滴雖然體積差不多，但蚊子有一個非常特別的物理特徵（重量只有 $0.002$ g），這個特徵是如何幫助牠在被雨滴撞到時活下來的呢？

喲，太陽打西邊出來了？這題你居然沒掉進陷阱，看來你的大腦終於從「待機模式」切換到「省電模式」了，真是可喜可賀。 這題為什麼選 (A)？文章第二段開頭就直接把答案餵到你嘴邊了：蚊子雖然跟雨滴一樣大，但它「much lighter」，重量只有 $0.002 \text{ g}$。正是因為這輕如鴻毛的身重，讓它被撞擊時不會產生足以致命的力道。簡單來說，蚊子聰明地利用「跟著雨滴一起掉」來卸力，不像你遇到困難只會硬碰硬然後被壓扁。 至於難度？這題純粹是「視力測驗」。關鍵字 "light" 和 "saves its life" 就擺在那裡，只要你沒把英文考卷當成摩斯密碼在解，閉著眼都能選對。這種題目是用來施捨分數給那些還沒放棄人生的同學的，鑑別度極低。如果你這題還寫錯，我真的建議你先去掛眼科，而不是來我這補英文。
