Question

【題目】閱讀理解
It might be something that you miss unless it's pointed out to you. Next time you go to a public bathroom, take a look before you sit down on the toilet seat. You won't see a circle shape, but something designed not connected in the front part: a U.
This is an open-front toilet seat, and thanks to the American Standard National Plumbing (水管裝置) Technology, it's the go-to for most public restrooms. This technology was created in 1955 and further developed by the Uniform Plumbing Technology in 1973, according to Mental Floss.
As to the plumbing rules which fit water seats, the first two requirements are as follows:
Toilet seats shall be of smooth, non-absorbed material.
All Toilet seats, except those within apartment units, shall be either of the open front type or have an automatic seat cover.
This part of the rules also clears up why you won't meet fur toilet seats in truck stop bathrooms. The reason for both of these rules comes down to health. With an open front, there's less surface area that can make incidental touch with your private regions. But what about the toilet seat covers you can use? Unfortunately, those don't offer as much protection against bacteria as you think they do.
They were also designed with women in mind, according to Lynne Simick, the senior vice president of technology development at IAPMO. The open front of the seat is fairly good for women.
Now that you know why the public toilet seat is shaped the way it is, learn which one is the cleanest you can use.
（1）What do we know about the toilet seat from the first paragraph?
A.It's round.

A.It has an automatic seat cover.
B.It is made from non-absorbed material.
C.It is very comfortable to sit on.

【解析】本文是一篇說明文，介紹為何馬桶座圈是Ｕ型的。從文章可知使用這種開放式馬桶座圈的好處是它能保護(hù)你免受細(xì)菌感染。
（1）考查推理判斷。根據(jù)第一段中的“Next time you go to a public bathroom, take a look before you sit down on the toilet seat. You won't see a circle shape, but something designed not connected in the front part: a U.”可知它被專業(yè)化。故選D。
（2）考查推理判斷。根據(jù)第四段中的“ With an open front, there's less surface area that can make incidental touch with your private regions. But what about the toilet seat covers you can use? Unfortunately, those don't offer as much protection against bacteria as you think they do.”可知使用開放式馬桶座圈的好處是它能保護(hù)你免受細(xì)菌感染。故選D。
（3）考查推理判斷。根據(jù)“As to the plumbing rules which fit water seats, the first two requirements are as follows: Toilet seats shall be of smooth, non-absorbed material. All Toilet seats, except those within apartment units, shall be either of the open front type or have an automatic seat cover.”對Ｕ型馬桶的介紹，A圖應(yīng)該是最好的選擇。
（4）考查主旨大意。根據(jù)第一段中的“You won't see a circle shape, but something designed not connected in the front part: a U.”和最后一段中的“Now that you know why the public toilet seat is shaped the way it is, learn which one is the cleanest you can use.”可知本文介紹為何馬桶座圈是Ｕ型的。故選B。
