Finally, you finish all your schoolwork and sit back in your chair. Suddenly you feel a headache and realize your eyes are painful. What’s going on? Doctors say that many students are spending too much time in front of screens, especially during online classes. The following might be of some help to you. |
|
THE 20-20-20 RULE This gives your eyes a break from long screen time. It suggests looking at something at least 20 feet away for 20 seconds after 20 minutes of work on the screen. You can then continue working pain free. |
•Studies show that people blink(眨眼睛) less often when looking at a screen. Keep your eyes wet by blinking often or using eye drops. |
•Sit up straight about an arm’s length(长度) away from the screen. Make sure you’re looking down at your screen. Stand up and exercise often to avoid neck and shoulder pain. |
|
•What about blue light blacking glasses (防蓝光眼镜)? They may look cool, but research shows that blue light isn’t the biggest cause of eye tiredness. So ask doctors about computer glasses before putting them on.

The Value of Negative Results
We all avoid failure（失败），and most of us fear it.However，without failure，progress would be impossible.What does success usually come after？Failure.It seems that one cannot exist（存在）without the other.
Accepting failure is not easy for many，though we are often unwilling accept failure because our professional fame depends on success.（1） In the past ten years，for example，some scientific magazines have published reports of failed tests.It is believed that scientists can learn more "negative（负面的）"results and that this can finally lead to positive results.
（2） The ABN AMRO bank started an Institute （机构）of Brilliant Failures to learn more about what works and what doesn't in banking.Eli Lilly and Company had failure parties to study the drugs（药物）that don't work.
In fact，one of the business world's most famous failures became one of its biggest successes，in part because the product's makers learned from their mistakes.（3） The product，though unique（独特的）at the time，was expensive and heavy；besides，some of its most important features（特点）didn't work properly.As a result，Apple's CEO，Steve Jobs，believed in the product and he began to find out ways of improving it.In time，this led to the production of the iPhone and the iPad，two of the company's most successful products.
（4） Not only should we try to learn from it if we want to succeed，we must also be persistent（执着的）.Though Apple stopped selling the Newton in 1998，the first iPhone wasn't available until 2007.It took a lot of research and hard work to go from the Apple Newton to iPhone but in the end，the effort became successful.
All in all，there is a lot we can learn by studying mistakes.Perhaps the most important lesson is that failure and success are two sides of the same coin. （5）
A.One truly cannot exist without the other.
B.We are brave enough to face difficulties.
C.In the early 1990s，Apple created a phone called the Apple Newton.
D.The business world already understands the value of negative results.
E.The Apple Newton has won popularity with people all over the world.
F.However，things are slowly changing，especially in business and science.
G.The story of the Apple Newton can teach us an important lesson about failure.
