Football is so popular in China. Almost everyone is interested in the sport — the young and the old, boys and girls, and now even robots.

Recently at Hangzhou Guangming Middle School, kids from several schools played football with their robots.

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 score a goal. The robot with more goals wins.

Gao Linge, a boy from Hangzhou 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 program for it.”

Gao’s robot was eight centimeters tall and had two arms. It had four sensors (传感器) 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 so, 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 — the robot ran out of batteries (电池)!

“We’ll solve the problem and beat the other schools next time!” said the two boys.

Beavers(河狸) are a very unique species in the world of nature and wildlife——they are architects. Their dams are fine examples of engineering.

A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped(锥状的) pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter.

From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has “walls”, one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses.

Trees are essential to beavers. They eat the bark on the upper branches. But they must first fell the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree.

The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin(下巴) with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood.

2.Which of the following sentences is Not the reason why trees are important to beavers?

When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into their cars and go straight for the center of the storm. These people are willing to risk being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.

  “Storm chasing(追逐)” is becoming an increasingly popular hobby, especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.

  Although anyone can do it, storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for vacations during the storm season.

  Even then, storm chasing is not all adventure and excitement. “Storm chasing is 95% driving,” says Daniel Lynch, who spends most of his summer storm-chasing. “Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers.”

  However, for storm chasers, it is all worth it. “When you get close to a storm, it is the most exciting sight you will ever see in your life,” says Jasper Morley. “Every storm is an example of the power of nature. It is the greatest show on Earth.”
