Now satellites(卫星)are helping to forecast(预报)the weather. They are in space and they can reach any part of the world.The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成)。They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.

Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures,the meteor- ologists compare(比较)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change,too. In their next weather forecast, the meteorologists can say this.

So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon,perhaps , they may be ablet to forecast the weather for a week or more ahead(提前)

Alpha Go, a computer program, has beaten Lee Se-dol, a world-famous Go player (围棋选手), 4-1 in a competition. Lee has won 18 world championships over the past 21 years. The win is seen as a landmark (里程碑式的) moment for artificial intelligence (人工智能). The Alpha Go system was developed by British Computer Company Deep Mind.

Lee expressed great confidence ahead of the competition. However, after losing the first game, he said, “I was very surprised because I did not think I would lose the game.” Lee said he felt “regrettable (令人遗憾的)” about the result of the game. At a press conference held after the final match, Lee said he did not think Alpha Go was necessarily superior to (优于) humans.

It is played on a board made up of a grid (网格) of 19 by 19 squares. The game opens with players taking turns to place black and white pieces, known as “stones,” on the board. The aim, as its name shows, is to surround a larger total area of the board than your opponent (对手) by the end of the game.

The competition was held in Seoul. It attracted huge attention. The first match was broadcast online. It was watched by 60 million viewers in China alone, with an estimated global audience of 100 million. Alpha Go’s developer got US $1 million in prize money.
