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 (水管装置) 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.

【解析】本文是一篇说明文,介绍为何马桶座圈是U型的。从文章可知使用这种开放式马桶座圈的好处是它能保护你免受细菌感染。
(1)考查推理判断。根据第一段中的“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.”可知它被专业化。故选D。
(2)考查推理判断。根据第四段中的“ 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.”可知使用开放式马桶座圈的好处是它能保护你免受细菌感染。故选D。
(3)考查推理判断。根据“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.”对U型马桶的介绍,A图应该是最好的选择。
(4)考查主旨大意。根据第一段中的“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.”可知本文介绍为何马桶座圈是U型的。故选B。
