There are about 80.000.000 mines under the ground in more than 60 countries. It is difficult and dangerous to clear these mines.About 50 people including many children were killed or hurt each day.In 2003，APOPO，a Duch research company that trains the animals,came up with the idea of using rats to search for the mines.
The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell.The rats were about 75 cm long and weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.
In January 2004，the  APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later，the rats were no longer afraid of people and the things around them.Then they were trained to connect a click sound with food.After the rats had learned that ,the trainers then taught them to tell the different between the smell of mines and other smells.When the rats could do it，the click was sounded and they were given a bit of bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“You have to be patient.Sometimes I get angry,but then again.I tell myself these are animals.”
After nine months’ training,the rats were taken to 4 minefield. They ran across the minefield ,stopped, sat and searched the ground to tell the deminers that they smelt out a mine. Then the mine was cleared.It had taken two deminers a day to clear a 200 m² minefield. But with the help of two rats they could finish it in two hours.
The rats and the deminers saved thousands of lives.“The rats did this job much better than we expected.So far they have helpde to make almost 2.000.000 m² of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.
【小题1】The APOPO trained the rats to search for__.

Animals grow up in different ways. They have lots of lessons to learn.
Some animals are born helpless but their mothers protect them. A newborn kangaroo is the size of a bee. She stays in her mother’s safe pouch. She doesn’t open her eyes for at least five months. A newborn monkey cannot walk. He is carried by his mother.
Other baby animals can walk soon after they’re born. They learn to run with their mother when danger is near. A baby zebra（斑马）can run an hour after she is born.
Some baby animals are born in a place that is safe. Other baby animals are born in the open. Baby wolves are born in large holes. A baby elephant is born on open, grassy land. Other elephants make a circle（圈）to protect her.

Animals that drink their mothers’ milk are called mammals. A mother bear’s milk is fatty and rich. Baby bears need lots of fat to keep warm in winter. They have milk for six months. Baby zebras drink milk for six months or more! As baby animals grow they need solid（固体的）food. Baby lions eat what their mother can catch.
【小题1】Which baby animals don’t open their eyes for at least five months?

There has been a lot of rain in California recently. Villagers and leaders there begin to be worried because they have found two birds died from a disease, West Nile Virus(病毒).
West Nile Virus is carried by mosquitoes(蚊子).The symptoms(症状) are just like the flu. However, it can cause dangerous brain problems.

People can get the disease if they are bitten(叮咬) by mosquitoes with West Nile Virus.
The government is trying its best go stop the spread of West Nile Virus. People are asked to wear long sleeves(长袖)and pants, close their windows and shut the doors.

Television has a huge influence on our lives. It is one of the most important ways of getting information. People spend part of their spare time watching television, and much of what they learn comes from it.
What we see on TV — movies，news shows, sports shows, advertisements and so on have increased our knowledge and have changed the way we learn about the world today. However, not everything on TV is true.
Most of the viewers (观众) are children. Television sometimes is like a baby-sitter. It spends more time with children than parents do. But it keeps them in the living room away from healthy outdoor activities. They spend less time playing soccer or walking in the park or playing games in the yard.
Of course, there are some programs on TV that are good for children. But there are also some shows which are bad. Children should not watch unhealthy shows. Maybe we can't change what is on TV, but we can choose what we watch. Do you agree?

The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are small and light and you do not need much space for them. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can only buy telephone cards, and some cards cost up to ￡4,000.The first Japanese card has a value of about ￡28,000. Most people only see cards with prices like these in their collectors’ magazine.

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.
The Lizard house
Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑风格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.
【小题1】What is the best title (标题) of the passage?
A. Green house of the future.
b. The greener, the better.
C. How to build green houses.
D. Changes of the houses.
【小题2】We can heat water, produce electricity or create fresh air for the home            .
A. with the root of a leaf.
b. with the energy from sunlight.
C. with the soil under the ground
D. with gardens on its walls.
【小题3】What will happen to the cover of the lizard house when it’s in the bright sun?
A. It will take in light.
b. It will produce energy.
C. It will turn dark.
D. It will turn white.
【小题4】The passage seems to tell us that meals at home in the future            .
A. will be more delicious.
b. need more cooks.
C. cost as much as possible.
D. will be greener.
【小题5】A chimney can be a useful air conditioner but it used to cause          .

The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鸽子). Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way.
Human (人类的) messengers (persons carrying messages) are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system(电子印刷系统) could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each.
Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about the pigeons in the newspapers around the world.
