We have known for a long time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at particular times. It is not as simple as we might think, as new experiments have shown. In one experiment, flowers were kept in darkness. We might expect that the flowers, without any information about the time of the day, did not open as they usually do. In fact, they continued to open at their usual time. This shows that they have some mysterious (神秘的) way of knowing the time.

Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of “inner clock”. This discovery may not seem to be very important. However, it was later found that not just plants but also animals including man have this “inner clock”which controls working of their bodies and their activities.

Human beings, then, are also controlled by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food. And our ability to concentrate(集中).

When people want to find something on the Internet, they often say,“Let’s Google it!”It means “Let’s search for it on the Internet!”

It all began in the summer of 1995, Larry Page, 24, and Sergey Brin, 23, met at Stanford University. In their project, the two students came up with a plan to make a new search engine(引擎). They founded(成立)Google a year later. It became a company on September 7,1998.

Google is not the first search engine, but it is certainly the most successful. Google’s worldwide market share(市场占有率)was as high as 82.8 percent last year, according to Marketshare. Hitslink.com.

Before Google,search engines ranked (排名) websites simply by how many times the webpage has been visited. Page and Bin used a completely different way, by the number of other websites that linked(链接) to that site. Google helps people find the most important site that connects to their key words.

As popular as Google in the English world, in China, Baidu is the most popular and biggest search engine. It held a market share of nearl y 80 percent for web search in 2012.

Baidu was started in 2000 by Li Yanhong and Xu Yong. It offers searches for website, audio, images...It also provides the largest online Chinese encyclopedia(百科全书)，Baidu Baike.
