Have you ever wondered?
1. Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.
2. What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.

Many people hurt their backs when they try to lift heavy things from the floor. It is easy to hurt your back muscle(肌肉) when you try to pick up a heavy thing. However, there is a correct way to lift things from the floor. If you pick up heavy things correctly, you probably will not hurt your back.

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.
