题目列表(包括答案和解析)



Recently,a solar powered(太阳能动力的)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 1.6k 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
【小题1】How long did the first flight of the solar powered plane last?

There are about 80,000,000 mines*  under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50  people including many children were’ killed ‘or htirt each iay.  In 2003,  APOPO,  a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng 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.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.

  In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference 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 banana.  The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu.  “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 a minefiel山  They’ran across the minefield, stopped, sat and scratched 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㎡ . minefield,  but with the help of two rats ‘they could finish it in two hours.

  The rats and ~he deminers saved thousands of lives,  “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.

1. The APOPO trained the rats to search for     .

A. children    B. animals      C. mines     D. bananas

2. While training the rats, the trainers have to be

Dear Gramps,

    I was so upset last week when somebody stole my Super Racer from the park by your house. I called up the toy company but they said they have only red, blue and green racers. Dad called Cobb's Toy Store today and found out they might have purple ones. Can we go there when I come to visit you next week?You and I were only gone for a few minutes to the shop down the street to get ice-cream and cookies. Maybe the thief was watching us. Mum was surprised when I told her the racer was stolen. She said she used to leave things at the park all the time when she was young. Once she even left her bicycle for two days near the swimming pool.

    Tell Grandma that I like the food she made last time. Ask Grandma if we can have pancakes with sugar for breakfast when I come this time. I have packed in my towel, comb and soap. Tell her this time I won't forget to pack in my toothbrush.

Love

Toby
