(2019·武汉市武昌区调研)Every now and then, a product comes along that proves itself a complete game-changer, as is the case with a new British brand and invention, Eyejusters — the reading glasses that you can focus yourself — for less than ￡ 70!

With 6 in 10 people wearing glasses in the UK, those with perfect vision are increasingly in the minority. And of those who do require glasses, many find themselves requiring two or three pairs of glasses

everything else, this also means carrying around (and trying not to lose) those extra pairs!

Eyejusters allow you to instantly change the lens (镜片) strength of your glasses with hidden dials, tucked just inside the frames themselves. Eyejusters work by the wearer simply turning the concealed eyeDials to change the focus to fit your needs. The lenses adjust from ＋0.00 to ＋3.00 D. They also have anti-scratch technology and are lightweight in design so you aren't paying the price of comfort for convenience.

The creator of Eyejusters, Owen Reading — who came up with the idea for Eyejusters with friend David Crosby, who studied physics at Oxford with him, explained: “Lots of people need reading glasses but they need glasses with lots of different strength. They might have a pair with ＋1 prescription－strength lenses for the computer, ＋2s for reading and ＋3s for really close-up stuff. Eyejusters replace the need for multiple pairs of reading glasses, by covering the whole range from zero to ＋3, which is the strongest you will find in over-the-counter products.”

He added: “If you wear reading glasses, these are a much more flexible alternative. You can put them on and just turn the dial until what you want to see comes into focus. They are much like using binoculars (双筒望远镜)．”

语篇解读：本文是一篇说明文，介绍了一种视力调节器，人们可以调整镜片焦距以达到不同的目的。

5．Which has the closest meaning to the underlined part “on top of” in Para.2?

in

order to complete different tasks throughout the day. As well as being an added expense on_top_of

A．Joan stays on_top_of the news by reading newspapers. B．A submarine can run under water as well as on_top_of water. C．When I turned the corner, I was right on_top_of the post office. D．He promised to help us and on_top_of that he lent us many books. 解析：选D 词义猜测题。画线部分上文讲的是，很多人需要两三副眼镜来完成不同的任务，而画线部分所在句是说这不但是一笔额外的费用，还意味着到哪里都要带着额外的眼镜。由此可以推断，on top of 的意思是“除……之外”，所以D项表达的含义与画线部分最接近。

6．Eyejusters are popular for the following reasons EXCEPT their ________. A．new brand C．light weight

B．anti-scratch technology D．low price

解析：选A 细节理解题。根据第一段最后的“for less than ￡ 70”可知，它的价格低，排除D项；根据第三段最后一句中的“They also have anti-scratch technology and are lightweight in design”可知，它有抗抓痕技术，还很轻便，排除B项和C项。故选A项。

7．How can you make Eyejusters serve different purposes? A．By folding glasses. C．By combining glasses.

B．By adjusting lenses. D．By changing lenses.

解析：选B 细节理解题。根据第三段首句“Eyejusters allow you to instantly change the lens (镜片) strength of your glasses with hidden dials, tucked just inside the frames themselves.”可知，人们通过调整镜片的焦距来服务于不同的目的，所以选B。

8．Who need Eyejusters most according to Owen Reading? A．People having perfect vision. B．People wearing reading glasses. C．People changing glasses constantly. D．People preferring comfortable glasses.

解析：选C 推理判断题。根据第二段第二句可知，为了完成一天之内不同的任务，很多人需要两三副眼镜。Eyejusters这种新型的眼镜正好可以弥补这个缺陷，可以通过调整镜片焦距来达到不同的目的，所以选C。
