Blue light before bedtime can make it harder to sleep, and the screens on phones, computers, and televisions send out plenty of blue light. This is all true. But if you're focused on blue light as a major problem affecting your sleep or your eye health, it's time to look at it from another aspect.

As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It's part of sunlight, and your eyes are exposed to plenty of it all the time. You ' re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well--so in a sense, we already have built-in blue blocking protection

Adding more protection isn't likely to help though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money: these products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.

The American Academy of Ophthalmology doesn't recommend blue-blocking products, either. Instead if you're concerned about your eye health or your ability to get to sleep on time, you already know what to do:

Put the screens away at bedtime. Read a book or find something else to do. While you're using screens take a 20-second break every 20 minutes to look at something 20 feet away ( the "20-20-20 " rule ). If you get dry eyes when you look at screens for a long time, use eyedrops labeled artificial tears.

1.What do people think of blue light generally?

A.It is a necessary part of sunlight. B.It is magical and rare.

C.It is the major factor affecting sleep. D.All electronics send out blue light.

2.What did the studies in mice find?

A.Mice can see clearly in the dark. B.Our eyes actually block blue light well.

C.Eyes can be long exposed to blue light. D.Blue light can damage mice's eyesight.

3.What can we know about blue-blocking products?

A.They block only 15% of the blue light. B.Few have much effect on the blue light.

C.They can prevent much harmful lights. D.They are thought highly of by experts.

4.What could be the best title for the text?

A.How can Blue Light Be Prevented? B.Why does Blue Light Make Sleeping Hard?

C.Are Blue-blocking Products Necessary? D.What will Blue Light Affect Actually?

Manage your time well for each module(单元), but also make sure you get a good balance between work and social life. That is vital for life in general.

Set aside time specifically for each subject. Try to study one subject a day. You need to balance time. If you are bad at balancing things, make a personal timetable. Even if you do not stick to it, you will have an idea what you should be doing each day. This is better than trying to do everything each day and, at the end of the week, not achieve anything. Also, try to keep your weekends free of studying. Only study at the weekend if you really have to.

I had to learn to balance work, study and family when I was at college. I was a retail assistant working part-time and had at least four modules to complete at the same time at college. I also had to help around the house doing household cleaning and shopping at times. I managed to finish my college work on time, which was very difficult and hard, and still hold down a job.

Why was it possible? Because I only thought about my part-time work when I was at work on the weekends and my college work had to be done from Mondays to Fridays before the weekends. This was hard—but you need to set a timetable for yourself. It was an achievement when I finally realized that things have to be done in order, and need to be organized as well.

Balancing study and other aspects(方面) of your life can be a problem if you have a job or a family, but planning in advance is helpful. Use the time you have well. Do not leave anything until the last minute, as this will only cause problems.

1.The underlined word“vital”(in Paragraph 1) means_____________.

A.common          B.necessary         C.easy          D.difficult

2.According to the passage, which of the following is NOT the advice the writer gives?

A.Try to study many subjects in a day.            B.Try not to study on the weeekends.

C.Plan in advance.                            D.Try to set a timetable.

3.It could be inferred from the passage that__________.

A.the writer has a part-time job as an assistant when he was at college

B.you need to set a timetable for yourself

C.you should make a personal timetable if you are bad at balancing your time

D.the writer can arrange his time well when he was at college

4.What is the passage mainly about?

A.I had a good time during my college.

B.How to study well at college.

C.Balance time between study and other aspects of your life.

D.How to plan your things in advance.

What would work be like if you had no boss?Imagine you could make all your own decisions and no one told you what to do.

A Swedish software company,Crisp,decided to get rid of their CEO.First,they needed to find out what a CEO actually did.Then they shared those duties among staff and board members,which is exactly what they did.And the employees believes it's been a good change.An employee named Heinrik Kniberg says the company can now act faster,"If you want to get something done,you stand up and start driving that.Workers are also more active and satisfied."And any big decisions are made during the all-member meetings several times a year.

So,if it's working well for Crisp,could this model become more widespread? Online retailer（零售商）Zappos tried out a similar plan but had unpleasant results.Almost a fifth of its staff decided to leave,and CEO Tony Hsieh admitted that "self-management is not for everyone".Mr Houston,founder of file-sharing service Drew Dropbox,says that total freedom doesn't always feel good,because you no longer know what you're supposed to do,what is important and you're bumping up against other people."

Day after day you are glued to your computer screen. You cannot get enough of online games, net shopping or cyber surfing. Your social life gets worse, and so does your health. Chances are that you are addicted to the Internet and you need counseling.

On November 8, an Internet Addiction Disorder (IAD) diagnostic manual（诊断手册）was approved by a group of psychologists in China, who agreed that Internet addiction is a mental disease. According to a report on Xinhuanet.com, the manual for the first time gives a clear time standard for diagnosing IAD, saying that surfing the Internet for more than six hours a day, not for the purpose of studying or working, and having done so for less than three months, might be a symptom of IAD.

Addiction symptoms vary

Besides the long online time, some other symptoms would also help doctors diagnose IAD patients, such as having a strong desire for the Internet and feeling physical discomfort, becoming easily angry, being unable to concentrate on things or finding it difficult to sleep if unable to get online.

Apart from these conditions, other symptoms are also listed in the manual. If a net surfer cannot get out of the virtual world of Web games, which has already affected his/her capability to study or work, or he/she feels little interest in doing anything but jumping online or is afraid to communicate with others, he/she is also considered to be an IAD sufferer.

According to the World Health Organization, mental disease sufferers have two major characteristics: they bring suffering to both themselves and their families, and their abilities to be involved in social activities are affected.

Mental illness stigma（污名）

However, it has resulted in a backlash（反对）from the public, due to the fact that mental disease is a very sensitive term to Chinese.

Many netizens dropped comments expressing their doubts about the manual, saying that they could not accept they might be suffering from mental illness just because they spent too much time on the Internet.

Experts said there is a misunderstanding of the manual. Explaining that IAD sufferers are not “crazy people”, they call on society at large to change their understanding of mental disease. Mental disease covers a wide range of psychological or behavioral problems, such as depression.
