There are many colors in nature. But do you think that a color has weight? I think you'll say 6/no". But I'm afraid you are wrong. If you don't believe it, you may do a small experiment(实验).

  First, put two objects with the same weight into two boxes. Then cover the boxes.Third, wrap(包裹) one box with a red piece of paper, the other one with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.

 Why do you think so? A scientist found that different colors have different weights in man's mind. That is to say, every color has its own weight in our mind.

 The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say S07 That is because every color stands for (代表) a kind of light with a certain wavelength,(波长). It reaches our brain through sense organs

 According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you'll be nervous or even get ill.  For example (例如) ,  you like blue and hate red.  If you stay in a room with red windows, wallpaper and furniture（家具) for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only an hour.  And, if a person walks out of a blue room and into a red room, his temperature will rise.That means our body temperature will change with different colors.

    Almost all cultures celebrate the end of one year and the beginning of another in some way. Different cultures celebrate the beginning of a new year in different ways, and at different times on the calendar(日历).

    In Western countries, people usually celebrate New Year at midnight on December 31st—January 1st. People may go to parties, sometimes dressed in formal(正式的) clothes, and they may drink champagne(香槟酒)at midnight. During the first minutes of the new year, people cheer and wish each other happiness for the year ahead. But some cultures prefer to celebrate the new year by waking up early to watch the sunrise. They welcome the new year with the first light of the sunrise.

    Many cultures also do special things to get rid of(摆脱) bad luck at the beginning of a new year. For example, in Ecuador(厄瓜多尔), families make a big doll from old clothes. The doll is filled with old newspapers and firecrackers. At midnight, these dolls are burned(燃烧) to show the bad things from the past year are gone and the new year can start afresh(重新). Other common traditions to keep away bad luck in a new year include throwing things into rivers or the ocean, or saying special things on the first day of the new year.

    Other New Year traditions are followed to bring good luck in the new year. One widespread(普遍的) Spanish tradition for good luck is to eat grapes on New Year's Day. The more grapes a person eats, the more good luck the person will have in the year. In France, people eat pancakes for good luck at New Year. In the United States, some people eat black­ eyed peas(豌豆) for good luck—but to get good luck for a whole year you have to eat 365 of them!

    After years of research and testing, the hybrid car was developed and put on the market. It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and save our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car's engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it produces electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas". When it completely runs out, the warning reads, "YOU ARE NOW OUT OF GAS!" Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

    Goal(射门)! Football, or soccer, is one of the world's most popular sports. The game first came from old China, though the modern football game began on the streets of old England. The rule is simple: get the ball in the other team's goal, not using your hands or arms. With simple rules and easy equipment(设备), people can play football anywhere. But the game needs teamwork.

    The men's game came into the Olympics at the 1900 Paris Games in France. The women's game came into the Olympics at the 1996 Atlanta Games in Georgia. At the Olympics, players play for two 45-minute halves, with 11 players on each team.

    At the Olympics, we make 16 men's and 12 women's teams into groups of four teams. Each team plays against every other team in their group. The best eight teams in the men's and women's competitions move onto the quarterfinals. In the end the best one will become the winner of the game.

In the year 2070，most of you will be more than 50 years old.The good news is that travel might become smarter by that time.To catch people's eyes and increase the numbers of passengers，European airline （航空公司）（发布）easyJet 2070：The Future Travel Report.Let's take a look at some mind—blowing ideas.
