Some colors people see late at night could cause signs of the condition mental health experts call clinical depression(临床抑郁症). That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression.

Doctors use the word clinical depression to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide.

In the new study, American investigators designed an experiment that exposed hamsters(仓鼠)to different colors. The researchers chose hamsters because they are nocturnal, which means they sleep during the day and are active at night. The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water.

Randy Nelson, at Ohio State University, says animals that slept in blue and white light appeared to be the most depressed. “What we saw is that these animals didn’t show any sleep interruptions at all but they did mess up biological clock (生物钟) genes and they did show depressive sign but if they were in the dim red light, they did not.” He says there’s a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness.

Several weeks ago, kidsPost did a story on “The Art of Video Games” at the Smithsonian American Art Museum. The exhibition has created debate with some people saying that as fun as video games are ,they are not works of art. Other people say that videos games may be a new form of art and that they belong to in museums. We asked readers for their opinions on the topic. Here are a few of the letters we received.

A video game is like a painting on a screen. In order to make a video game, you have to think of something original(新颖的)to reach the players. This is the point of Art.

---Mary Pottanat,13

I believe video games are not a form of art. Art should be a visual (视觉的)and creative expression of feelings. Although it is arguable that video games are visual ,they do not express feelings in any way.

---Prannab Kirshnan,12

However exciting video games are, they are not art. Painting is art, but not video games. Art has beauty and culture that no technology could ever compare to. Even though you can create art in some video games, the “ Mona Lisa” wasn’t painted with Nintendo.

---Caroline Kaplan,10

Art is a way of communicating ideas to the public in a way that is fun to them. The “public”, who in this case are kids and adults, are finding these video games from different time periods interesting. Video games would not have been art if it had not been for the kids and adults attracted by “the art of video games”.

When you buy cooking oil in the supermarket, you may notice that some brands are labeled as “GM (genetically modified)-free”. So, what is genetic modification? Are GM foods safe?

These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administrati0n (FDA) in the US announced that it had approved the AquAdvantage salmon to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world.

GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster.

Although the FDA has said “food from the fish is safe to eat”, some believe that scientists can’t completely understand the potential health risks of GM foods, simply because they’re so new. Others worry that the fish could escape into the wild and cause ecological problems.

GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides on crops and increases yields.

While GM animals are new, GM crops have already appeared on our plates: A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for tile Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya and import GM soybeans, corn, rape, cotton and beets from abroad.

Due to safety worries, many countries have regulations for producing and selling GM food.

In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable, and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu.

The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary, except that a product cannot be labeled as “GM-free” if genetically modified materials are used.

In China, GM foods can only be produced after strict tests by the Ministry of Agriculture say that they are safe. All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper.

1.According to the text, the AquAdvantage salmon .

A. tastes better than normal salmon

B. is a product that mixes several types of fish

C. has a gene from a different type of salmon

D. remains to be approved in several countries

2.One of the reasons for many people to worry about the AquAdvantage salmon is that .

A. the gene that makes them grow faster can work on humans too

B. there are possible health risks that even scientists might not have figured out yet

C. they could possibly become threats to other wild species

D. they are not nutritious enough or might taste strange

3.From-the text, it can be concluded that GM crops .

A. no longer cause any controversy

B. have already been planted in some countries

C. are popular because they don’t need pesticides

D. can increase yields, making them welcome in countries like Japan

4.Which of the following is TRUE about regulations for producing and selling GM food?

A. All food with GM content must be labeled in European countries.

B. In the US, the AquAdvantage salmon will have to be labeled as GM food.

C. In France or Germany, every GM food that is about to go on the market must be reported at least 120 days before release.

D. In China, all food that is made from GM crops or contains GM ingredients must be clearly labeled on the package.

A group of graduates, successful in their careers, got together to visit their old university professor.Conversation soon turned into complaints about stress in work and life.

Before offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and a variety of cups — porcelain, plastic, glass, crystal, some plain looking and cheap, some extremely expensive — telling them to help themselves to the coffee.

When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice looking expensive cups were taken up, leaving behind the plain and cheap ones.While it is normal for you to want only the best for yourselves, that is the source of your problems and stress.The fact is that the cup itself adds no quality to the coffee.In most cases it is just more expensive and in some cases even hides what we drink.What all of you really wanted was coffee, not the cup, but you consciously(有意识地) went for the best cups...And then you began eyeing each other's cups.

Now consider this: Life is the coffee; the jobs, money and position in society are the cups.They are just tools to hold and contain Life, and the type of cup we have does not change the quality of life we live.Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has provided us."God makes the coffee, not the cups.Enjoy your coffee!"The happiest people don't have the best of everything.They just make the best of everything."

Live simply.Love generously.Care deeply.Speak kindly.Leave the rest to God.

While you may think that being smart and talented would logically make someone successful in running a business, unfortunately, this is often not the case.

This problem starts back in school when the stressful “group projects” are first assigned .The smartest don’t want to risk their grade in the class by dividing the work equally and hoping that an average student does his part well. They just take over and do the whole project themselves.

And thus begins the smart-people work cycle. The smartest people do just about everything better than most everyone else until it comes to running a business. They are not better; they are screwed(束缚). A smart person who can’t stand someone else doing a job badly does everything himself. Then, he is stuck with the one-man band “job-business” and ends up not being able to grow. However, it is quite interesting and strange that some slackers(偷懒的人) are better suited to be a business leader than the “smart” people. They figured out early on to surround themselves with smart people who would do the work that they themselves don’t want to do.

Smart and talented people often have a gift for the unusual, complicated or different. They don’t like to follow the KISS principle (keep it simple, stupid), which is required to make a business succeed. Maybe you think the global presence of McDonald’s complex, but in fact, in the company, every single task is broken down into easy-to-follow steps and everything has been standardized. These successful companies have just a few smart enough people to run the majority of the tasks in a way that can’t be screwed up by their average employees. So, being smart or talented isn’t going to help you unless you can use your talent to figure out a way to simplify those tasks that will make a business successful.

Another issue with the smart people starting businesses is that they often have the most to lose. The smarter you are, the more choices you have available to you. You will be able to make a lot of money in various fields and have room in your career to become promoted. This means that when you start a business, you have a lot more to risk than those who are not equally smart. This is often referred to as the “golden handcuffs” dilemma.

So, don’t be surprised when the person “MOST Likely to Succeed” from high school ends up as an employee and it is one average student that finds success in his or her own business.
