Recently,a solar powered(太陽能動力的)plane took to the sky for the first time. It had passed an important test on the way to travel around the world.
The plane took off from an airport in Switzerland(瑞士)at 45km an hour. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight, the plane did several turns. It climbed nearly 1.6km above the countryside.
Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
The plane flies at 70 km an hour. That is faster than a bike and slower than a car. Piccard and pilot Andre Borschberg will take the plane around the world. The pilots will keep the plane in the air for up to five days at a time.
“We want to fly it day and night with no fuel (燃料),” Piccard said
【小題1】How long did the first flight of the solar powered plane last?
A.45 minutes | B.60 minutes | C.70 minutes | D.90 minutes |
A.It uses no fuel | B.It’s the fastest plane |
C.It can fly highest | D.It’s the heaviest plane |

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.
1.The APOPO trained the rats to search for__.

People do not usually like floods but some farmers need floods when their fields are too dry.When there is a flood, the water carries mud and sand from the river bed to the field near the river. When the water goes away, the mud and sand become good soil.
People in many countries tell stories about a very big flood. The flood covered the world. Here is just one of those stories.
A long , long time ago there was a man called Noah(諾亞). He lived with his wife, his three sons and his sons’ wives. One day, Noah heard a voice. It said: “Noah, soon there will be a big flood. You must build a boat. You must put two of every animal and bird in the boat. Many, many people will die in the flood but you and your family will be all right.”
Noah and his family built a boat. They put two of every animal and bird in their boat. They put food in the boat, too. Then it started to rain. It rained for 40 days and 40 nights. The water covered the world. The hills and mountains looked like islands. Noah’s boat stopped on the top of the mountain. At last the rain stopped and the flood went away. There was a beautiful rainbow in the sky. And the animals and birds left Noah’s boat. They ran, jumped, walked and flew away to live on the mountains.
According to the story, answer the following questions:
1.Can floods be good for farmers?
______________________________________________
2.What did Noah build to protect his family from the flood?
________________________________________________
3.How long did the rain last?
