Football is so popular in China. Almost everyone is interested in the sport,young and old, boys and girls,and
now even robots.
Last week at Hangzhou Guangming Middle School, kids from several schools played football with their robots.
The robot football is very different from human football. Only two robots play in each match. The field is as big
as a ping-pong table. One half is black and the other is white. Each robot tries to catch the " football" and push it
into the goal. The robot with more goals won.
Gao Linge,a boy from Guangming Middle School, helped make one of the robots for the match.
" My school bought the main board (主板) ," said Gao,14. " Then I decided what my robot looked like and made
a computer programme for it. "
Gao's robot was eight cm tall and had two arms.It had four sensors (感應器 ) to " see " and "kick" the football.
Ying Xuehai, a 12-year-old student from Gao's school,also made a robot. His robot played against Gao's.The match
decided who would go to the final game. Ying lost the game. So he gave many of his robot's parts to Gao.
Even with the help, Gao's robot didn't win the final. It played well in the first five minutes.
Then it slowed down. By the end of the match,it could hardly move.
What was wrong?
Gao and Ying found the problem. Their robot ran out of batteries(電池) !
" We'll solve the problem and beat the other schools next time ! " said the two boys.

科目：初中英語 來源：期末題 題型：閱讀理解
Many places in the world need more fresh water. Every country is trying to find ways to turn salt water
into fresh. Why aren't there many factories like the Symi factory?
In some places, the sun is not hot enough. Or it does not shine every day. In such places, other ways of
heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea
water with high heat, a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried. One way is
freezing. The fresh part of salt water freezes (冷至結冰) first. To get fresh water, the bits of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way
for each place.
Symi's way seems very good for small, hot places. It doesn't make very much water at a time. But the
factory is easy to build and costs little. That is why people in many dry places talk about Symi!
