A leading biologist has found the angels and fairies that sit at top of Christmas trees did not get there under their own power.
Prof Roger Wotton, from University College London, found that flight would be impossible for angels with arms and bird-like feathered wings.  
"Angels cannot take off and cannot use powered flight,” said Prof Wotton. “They would need to be exposed to very high wind velocities at take off - such high winds that they would be blown away."
Some the world’s most famous religious paintings and architecture make most Americans believe in angels.
The study found that 68 per cent of the 36,000 adults thought that angels and demons (魔鬼) were at work in the world.
According to the latest study, angels lack the powerful muscles which allow birds to beat their wings.
Prof Wotton’s paper explores why there are so many stories about angels. “Angels are very powerful religious icons for people with faith. Their similarity to humans adds to their power. At the same time, they have wings on them because they are more than human. They take messages to heaven and therefore have to fly.” said the academic.

A. There will probably be no school on Mars.
B. It might take us two or three days to get to Mars.
C. There is a problem for us to live on Mars.
D. Food will not be the same.
E. First, people will have more space.
Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light.  【小题1】 
Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
 【小题2】  We could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better in many ways.  【小题3】  It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
 【小题4】 Every student can study, do their homework on the computer and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today.  【小题5】Meals will probably be in the shape of pills(药片) and will not be as delicious as they are today. Also, space travel will make many people feel ill.

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!

WHAT YOU’LL NEED: ● Soap           ● Water          ● Your hands! WHAT TO DO: 1. Make sure your hands are dry. 2. Rub your hands together until you feel the heat of your hands. 3. Now, use soap and water to get your hands very slippery (滑的). 4. Try to make friction happen while your hands are slippery. 5. Please write down what has happened. LET’S TALK! Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot. DID YOU KNOW? 1. Friction happens when you stop your fast running bike. 2. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it.         ?        Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction.

A Solar-powered Plane---Lowcarbon Earlier this month, a solar-powered (太阳能动力的)plane called Lowcarbon took off to the sky for the first time. It has passed an important test on the way to travel around the world. Lowcarbon took off from an airport in Switzerland(瑞士)at 45 km an hour. It slowly rose into the sky. “There has never been an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project. During the 90-minute flight, Lowcarbon did several turns. It climbs nearly 1.6 km above the countryside. Engineers plan to test a night flight in 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. “We want to fly it day and night with no fuel,” Piccard said. Piccard and pilot Andre Borschberg will take Lowcarbon around the world .They will make a few stops to change places and rest after a long time in the air----and to show off their aircraft. Lowcarbon flies at 70 kph on average(平均). That is faster than a bike and slower than a car. The pilots will keep it in the air for up to five days at a time.
