Ⅱ.理解
There are any Aerican expressions about insects—like bees, for exaple. Bees always appear to be busy, oving around their hoes, or hives. In fact, you ight say your house was a beehive of activity if your whole faily was helping you clean. You also ight say you ade a beeline for soething if you went there right away.
Here is an expression about bees that is not used uch any ore, but we like it anyway. We think it was first used in the nineteen twenties. If soething was the best of its kind, you ight say it was the bee's knees. Now, we adit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot stop talking about soething because she thinks it is iportant, you ight say she has a bee in her bonnet. If soeone asks you a personal question, you ight say “that is none of your beeswax”. This eans none of your business.
Speaking of personal questions, there is an expression people soeties use when their children ask, “where do babies coe fro？” Parents who discuss sex and reproduction say this is talking about the birds and the bees.
Hornets are bee­like insects that soeties attack people. If you are really angry, you ight say you are ad as a hornet.
Butterflies are beautiful insects, but you would not want to have butterflies in your stoach. That eans to be nervous about having to do soething, like speaking in front of a crowd. You would also not want to have ants in your pants. That is, to be restless and unable to sit still.

答案與解析：
在美國，有許多關于昆蟲的習語，其中關于蜜蜂、大黃蜂和蝴蝶的習語更受人們的青睞。這些習語的出現，使人們的語言變得更加豐富多彩。
16．D　推理。由第一段第二、三句可知選D。
17．C　細節理解題。由第二段前三句可知，習語“It's the bee's knees”人們已經不經常說了，因此我們不會經常聽到這個習語。
18．A　推理。由第三段第一句可知，如果一個人喋喋不休地說自己認為重要的事情，我們可能會說you have a bee in your bonnet。因此這個詞語應表示“不要再說了”。
19．C　推理判斷題。由短第一句可知，本要講述的是有關昆蟲的習語。在四個選項中，只有C項的bugs(蟲子)與昆蟲有關。
