How long are you willing to wait for a webpage to open before you start to lose your patience? Half a minute? A few seconds? Google engineers have discovered that even 400 milliseconds―as short as the blink of an eye―is too long for most Internet users.

A millisecond is one thousandth of a second. People hardly notice such a small time difference, but it does cause them to stop searching, reported The New York Times. “Without question, nobody likes to wait,” said Arvind Jain, a Google engineer. “Every millisecond matters.”

Nowadays, millions of smart-phones and computers are continually gathering and sending out information. With so many people downloading maps, sports videos, news and restaurant recommendations, you can get digital “traffic jams”. Meanwhile, users are expecting faster and faster service.

Google found that if one website is 250 milliseconds slower than another website, then people will visit it less often. This is why technology companies are now competing to be the fastest. Google said people do expect different things from different websites because they realize not all loading times are the same. For example, a person will be more patient waiting for a video to load than for a search result.

Even so, four out of five online users will click away if a video takes too long to load. This makes it difficult for video websites to choose between the quality of pictures and fast loading times.

Trying to get a higher speed has always been part of the history of the Internet. In the 1990s, when the World Wide Web first started to become popular, it was very crowded and slow; people called it the “World Wide Wait”. But engineers managed to fight the problem with new inventions. They laid a lot of fiber optic cables (光缆)for sending in high speed; they improved software so it would work more smoothly; they placed computer servers all around the world to be nearer to users; all this increased speed.

Nowadays we can enjoy much faster Internet. Famous search engines such as Google and Microsoft’s Bing usually find search results in less than a second. However, in order to meet the requirement of Internet users, these tycoons should never stop their steps.

1.The report from The New York Times suggests that

A. A millisecond is one thousandth of a second.

B. 400 milliseconds is not so long for most Internet users.

C. A millisecond has nothing to do with the Internet speed.

D. A millisecond really makes a difference to the Internet users.

A. The quality of pictures comes first for video websites.

B. Google is 250 milliseconds slower than other websites

C. Microsoft’s Bing is the fastest engine the world now

D. People are more likely to wait for loading films than maps

4.What does the underlined sentence mean?

A. Internet users are willing to see more search engines set up

B. Google and Microsoft’s Bing should help find the searching results

C. These companies should mind their steps, or they will break down soon.

2.Health

A good night’s sleep

Do you get the sleep you need?

When the morning sun looks in through our window, do you jump out of bed or go on lying?

Having enough sleep can make the difference between a great day and a terrible one!

Here are the tips for a good night’s sleep:

First, go to bed and get up at the same time, even if you haven’t gotten a good night’s sleep. Sleeping late for just a few days can change your body clock to a different cycle.

Also, avoid big meals at night. Eating heavy, rich food within two hours of bedtime can keep you awake. Your stomach works hard because of those fatty foods, and that may keep you up.

Your body produces a chemical called melatonin that helps you sleep. Light changes the amount of melatonin. It produces more in the evening and less in the daytime. So at night turn off your TV and PC. Also, don’t read from a backlit device(有背光的设备) like an iPad. Some scientists think that light from those devices stops your body from making melatonin. So turn those screens off at least an hour before bedtime.

After a good night’s sleep, you’ll be able to face a new day.
