There are about 80,000,000 mines (地雷) 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 Dutch 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 weighed about 1.35kg, 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 not afraid of people and the things around them anymore. 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 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 minefield. They ran across the minefield, stopped, sat and searched the ground to tell the domineers (排雷员) that they smelt out a mine. Then the mine was cleared. It had taken two domineers a day to clear a 200 ㎡ minefield, but with the help of two rats they could finish it in two hours.
The rats and the domineers 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 Weetjens, the head of the APOPO.
1.While training the rats, the trainers have to be ________.
A.clever B.patient C.brave D.serious
2.Which of the following is NOT TRUE according to the passage?
A.Each day about 50 children were killed or hurt by mines.
B.The APOPO started to train the rats in January 2004.
C.The trainers gave the rats food after they smelt out a mine.

Do you know what makes lightning(闪电)? Why does lightning strike(击打)?
Lightning strikes happen when ice and water in clouds rub(摩擦) together, and cause atmospheric(大气层的) changes. When this happens, it creates a static charge(静电). Lightning can strike inside the cloud, between two clouds or between a cloud and Earth. It's the last kind of strike that is the most dangerous for humans.
Lightning can be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches a temperature of 28，000℃. About 1，000 people are hit by lightning every year in the United States, and about 100 of them die as a result.
Lightning makes people shocked, and it happens all over the world! Scientists think that there are more than three million lightning strikes every day in the world—that's thirty strikes every second. An American man, Roy Sullivan, who worked in a park, survived from the most lightning strikes. Between 1942 and 1983, he was hit seven times! And he keeps the highest world record.
Lightning is sure not something to play with. When lightning strikes, it's best to stay inside a large building. To stay safe, do not stand under trees, on hills or near water. Also, do not lie down on the ground, or the electricity may go through you and cause a heart problem.
1.Lightning strikes ________．
A.happen thirty times each day
B.happen when there are big fires

巴黎自行车计划
Like all big cities, Paris has a traffic problem: lots of cars, lots of traffic jams and lots of pollution. So in 2007, the city began a plan called Velib to improve the situation.
Under the Velib plan people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first halfhour on the bike is free, but if you don't return it after 30 minutes, you have to pay. There are about 20, 000 of them in the city, and around 1, 450 bicycle stations.
Paris is not the first city to have a plan like this. Lyon started a "free" bicycle plan many years ago. And not everybody thinks it's a great idea. One Parisian said, "These bicycles are only for short journeys."
A city spokesman said, "The bicycle plan won't solve all of traffic problems, of course. But it might reduce pollution levels in the air. Traffic, together with factory smog, is a big problem. Everyone knows about global warming. It's because there's so much pollution in the world. The bikes might help people to lead a healthier life, too. There aren't any simple solutions to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems of our environment will get worse."
