Colours and Moods
Some people believe that colours can influence our moods. You may wonder whether it is true. In fact, colours can change our moods and make us feel happy or sad, energetic or sleepy. This article explains what colours can do and what characteristics they represent.
Calm colours
Have you ever walked into a room and felt relaxed? It could be because the walls were painted blue. Blue is a calm colour. It brings peace to our mind and body. Blue can also represent sadness, so you may say “I'm feeling blue” when you are feeling sad. White is another calm colour. It is also the colour of purity. Many women like to wear white on their wedding day.
Warm colours
Some colours, such as orange and yellow, can make you feel warm. People in cold areas prefer warm colours in their homes to create a warm and comfortable feeling.
Orange represents joy. It can cheer you up when you are feeling sad. Yellow is the colour of the sun, so it can remind you of a warm sunny day. Yellow is also the colour of wisdom. Some people prefer this colour when they hope for success.
Energetic colours
When you feel tired or weak, you should wear energetic colours like green. Green can give you energy, as it is the colour of nature and represents new life. However, it is also the colour of envy, so we may say someone is “green with envy”.
Strong colours
If you require strength in either body or mind, red may be of some help to you. Red is the colour of heat. It represents power and strong feelings. Wearing red can also make it easier to take action. This may help when you are having difficulty making a decision.

25-year-old Computer Engineer Murdered
Early today, the body of a 25-year-old man was found in West Town. The police have confirmed that the victim was a computer engineer. He was last seen leaving his office in East Town at about 7 p.m. yesterday. He said he was going to visit his parents.
The police believe that the murder took place between 9 p.m. last night and 1 a.m. this morning. They are still working at the scene of the crime to find out whether the victim was killed somewhere else and then brought to West Town, or killed at the place where he was found.
“We're asking anyone who saw anything unusual near Corn Street last night to contact us,”said Detective Lu, West Town's chief detective.“The victim was wounded with a knife and bled to death as a result. We're now checking the scene for more clues which will help solve the case.”
The police are also wondering if the victim had any enemies. He was single. He had many friends and a well-paid job. However, according to the record, he was guilty of computer crimes in the past.
“He was charged with breaking into several computer systems over the last year,”said Detective Lu. “We're not sure whether this made him any enemies. We suppose that the victim knew his murderer.”
So far, the only suspect is a short thin man who was seen running down Corn Street at 10 p.m. last night. A witness reported that he was breathing heavily and had blood on his shirt. However, the suspect could prove that he was somewhere else at the time of the crime and insisted that he was not guilty.
The victim's parents have offered a reward of ￥50,000 for any information that leads to the arrest of the murderer. Anyone who can provide useful information should contact the police.

Moving to Mars
Some people believe that humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted because of the rapid increase in population. It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.
At present, our spacecraft are too slow to carry large numbers of passengers to Mars — it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraft that travel at the speed of light! However, the spacecraft would travel so fast that the journey to Mars might be quite uncomfortable. Many people would feel ill.
Humans cannot survive without water, oxygen or food. So far, nobody knows whether there would be enough water or oxygen on Mars for people there. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills and would not be so tasty.
Gravity could be another problem. The gravity on Mars is only about three-eighths of that on the Earth. People would have to wear boots that are specially designed to prevent themselves from floating off into space.
Compared with life on the Earth, life on Mars would be better in some ways. People would have more space. They might live in houses with huge comfortable rooms. Also, robots would do most of their work so that they could have more time to relax.
There would probably be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online schools with “e-teachers”.
Life on Mars would be interesting as well as challenging.
