Every people has its own way of saying things, its own special expressions. Many everyday American expressions are on colors. Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz. Pink is a lighter kind of red. People sometimes say they are in the pick when they are in good health. The expression was first used in America at the beginning of the twentieth century. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health. Blue is a cool color. The traditional blues music in the United States is the opposite of red hot music. Blues is slow, sad and soulful. Duke Ellington and his orchestra recorded a famous song - Mood Indigo - about the deep blue color, indigo. In the words of the song: "You ain't been blue till you've had that Mood Indigo." Someone who is blue is very sad. The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling stomach may say she feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green. Sometimes a person may be upset because he does not have something as nice as a friend has, like a fast new car. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because that is the color of the back side of the paper money. The color black is used often in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people... Suppose a Mr. Brown says he is very happy because his three children are all in the pink, this means all his children are _ . A) lucky and wealthy B) gentle and modest C) fit and healthy D) creative and energetic

A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.But the extent to how much TV may be to blame is a question that the study leaves unanswered. The researchers used a national long-term survey of adolescent health to look into the relationship between media use and depression.They based their findings on more than 4,000 adolescents who were not depressed when the survey began in 1995. As part of the survey, the young people were asked how many hours of television or videos they watched daily.They were also asked how often they played computer games and listened to the radio. Media use totaled an average of 5 and one half hours a day.More than 2 hours of that was spent watching TV. 7 years later, in 2002, more than 7 percent of the young people had signs of depression.The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study.He says every extra hour of television meant an 8 percent increase in the chances of developing signs of depression. The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio.But the study did find that young men were more likely than young women to develop depression given the same amount of media use. Doctor Primack says the study did not explore why watching TV causes depression.But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also affect sleep, he says, and that could have an influence. The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives.Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people.The study found that happy people are more likely to be... More than 4,000 adolescents were chosen as the subjects of the study because they _ . A) were free from depression B) were fond of using the media C) attached much importance to their health D) could afford the time for the long-term survey

Question: A MILLION people on Mars within 100 years. This is the brave vision of Elon Musk, the founder of the space technology company SpaceX. "We need to be laser-focused on becoming a multi-planet civilization. That's the next step," he said in a recent interview with Aeon magazine. Musk expects to see about 80,000 people living on Mars by 2040. It's all about protecting the human race from extinction, according to Musk. The Earth has always been a ticking time bomb. As the sun begins to die, it will grow bigger, becoming what is known as a Red Giant. In 500 million years, the sun will have become large enough to kill off any plant and animal life on Earth, according to US scientist Edward Guinan. In a billion years, the Earth will have become a hot planet with little or no water. The brave dream of getting the human race to Mars is not only Musk's; others have made plans, too. A Dutch entrepreneur set up the Mars One foundation in 2011, hoping to be the first project to put humans on Mars. It received over 200,000 applications to become part of the first group of astronauts to go there. According to Mars One, "human settlement on Mars is possible with existing technologies." Water, food, energy, and oxygen are needed for life anywhere. According to Mars One, water that was still in the Martian soil would be boiled and taken out. By using a process called "electrolysis", astronauts could split water into hydrogen and oxygen for breathing. Astronauts on the International Space Station have already done similar things. Food can also be grown in space. Certain plants such as lettuce and onions can be grown using LED light for different color spectrums and much less heat. NASA has been researching this to prepare for visiting Mars. But how will people get there? The Mars One project plans to use SpaceX's Dragon capsule as part of its mission. But it is rumored that Musk already has a design in mind for a giant spaceship. He calls it the Mars Colonial Transporter. According to Elon Musk, the trip to Mars is significant because _ . A) Earth is not the only planet that is suitable for human beings B) settlement on Mars could save the human race from extinction C) the environment on Earth will be too harsh for human beings in a few hundred years D) a large amount of water has just been discovered on Mars
