Lake Victoria is the largest lake in Africa.It is also the second largest lake in the world.It is an important lake because it is one of the sources(源头) for the longest river in the world, the Nile River.Lake Victoria provides a source of water, food, and power for several African countries.Lake Victoria is a big part of African life.

Unfortunately, Lake Victoria has a problem.It is shrinking.There are several power stations at Lake Victoria in Uganda.These are on the Nile River, and besides producing power, they keep the water of the lake at a certain level.For the past forty years, that level has been 11.9 meters.Over the last several years, the water level has dropped by about 2.5 meters.There seem to be several reasons for this drop.

One possible reason is drought(干旱).Drought has been very bad in the area since 2000.Lake Victoria gets all of its water from rain, so the drought means less water in the lake.

However, some environmentalists believe that the real problem is the power plants(factories) on Lake Victoria.Uganda depends on those power plants for most of its power, and they made the power plants larger in 2000.Many people believe the power plants have been taking too much water off Lake Victoria.As a result, they have been asked to use less water until Lake Victoria goes back to its old level.

Whether the low water level is caused by drought or power plants, the result is the same.This is already a poor area of Africa, where many people live a really hard life.People, animals and plants around Lake Victoria will suffer even more from low water levels on the lake.Many people need Lake Victoria for fishing or growing food.Fish need the water to live, and animals need it for water.Plants around the lake will die without the water, and then more animals and people will suffer.Unless the lake fills soon, many people will suffer and die.

“How many common English words were invented by Shakespeare?”

How long did it take people to find the answer to this question 15 years ago? And now! you can google it and find the answer immediately!

Google is the most popular Internet search engine in the world. It was invented by two students, Larry Page and Sergey Brin. They met in 1993, when they were studying computer science at Stanford University, USA. They dreamed of producing something that could also answer any question in seconds.

Internet search engines at that time were slow and gave many websites that weren't useful. In January 1996, Page and Brin decided to make a better and faster search engine. They thought the results should be based on the most popular websites.

Nobody would give them money for their project, so they used their own money. They also borrowed money from family and friends. Then, in 1998, they were given achequefor $100,000, and they started their own company. Their first office was in a friend's garage. The company's name is Google, a word which comes from mathematics. A “google” is a very high number----1 followed by a hundred zeros.

The google search engine was soon used by thousands of people worldwide because it was fast, easy and correct. By 2002 it was the biggest search engine on the Internet. Now, more questions have been answered by Google than any other Internet service, from sport to science, and from music to medicine. Google hopes that in the future all the world's information will be put on the Internet, so that everybody can find everything.
