Don’t Make Me Wait

How long are you willing to wait for a web-page to open? Half a minute? A few seconds?

Internet engineers have 1 that even 400 milliseconds are too long for most Internet users.

A millisecond is one thousandth of a second. People 2 notice such a small time difference, but it does cause them to stop searching, reported The New York Times. Millions of smart-phones and computers are collecting and sending out information. With so many people downloading maps, sports videos, and news, you can get “3jam online”. Meanwhile, users are expecting faster and faster service. If one website is 250 milliseconds 4 than another website, then people will visit it less often. That is why technology companies are now competing to be the fastest.

【答案】

1D

2B

3E

4A

【解析】

随着科技的发展,人们的生活节奏越来越快,在浏览网页时,甚至400毫秒的时间也不愿等待,这反过来又督促了科技公司追求更快的速度。

1句意:互联网工程师发现,对于大多数互联网用户来说,即使是400毫秒也太长了。

根据句子结构可知,该空与前面的have搭配构成现在完成时,是句子的谓语动词;结合句意可知,空后that引导的宾语从句是网络工程师们所发现的情况,因此discovered意思合适。故选D

2句意:据《纽约时报》报道,人们几乎不会注意到这么小的时差,但这确实会导致他们停止搜索。

根据句子结构可知,该空修饰谓语动词notice,应用副词形式。结合上句话“A millisecond is one thousandth of a second.”可知,一毫秒是千分之一秒,是很短很短的一瞬间,因此人们几乎不会注意到,hardly“几乎不,符合语境,故选B

3句意:有那么多人下载地图、体育视频和新闻,你可能在网上遭遇堵车

由上句话“Millions of smart-phones and computers are collecting and sending out information.”可知,使用电脑和手机的人有上百万,这样会导致网络速度慢,就跟道路上的堵车一样。traffic意为交通,和jam组成短语traffic jam交通堵塞,符合语境。故选E

4句意:如果一个网站比另一个网站慢250毫秒,那么人们访问它的频率就会降低。

根据句意和空后的than可知,这个空应用比较级形式,且结合句意“then people will visit it less often”可知,网站速度慢,人们就不想访问了。slower更慢的,符合语境。故选A

【题目】 Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.

The eye-recognition (眼睛识别) program has already been tested in shops and banks in the USA. Britain, Spain, Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.

Eye-recognition is a course of recognizing iris (虹膜), which includes the following steps. First, a kind of machine needs to collect different examples of one’s iris from his eyes and store them. Second, when this person goes to the bank to take out money, this machine will have iris feature extraction (采集). Then, this machine will compare the examples kept in it with iris feature extraction. Once the examples and the feature extraction are the same, this person will be identified, and he will take out the money from the bank successfully.

However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We have already had machines that can tell who you are from your voice or the mark made by your finger. Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct now. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.

In the future your computer will be looking at you in the eye, So smile!
