(2017·四川重点中学高三检测)Can you imagine an engineer building a tall skyscraper without a plan？Someone said，“If you fail to plan，you plan to fail.” Success is no accident.It doesn't just magically happen.You have to plan for it to happen.As one guy put it，“You must plan for a great future.After all，you have to spend the rest of your life there.” We must have some kind of plan of what we want and how we'll get it.

You see，if you achieve nothing，you'll hit it every time.A wise person said，“If you've accomplished everything you've planned in life，then you've probably not planned enough.You're getting too old when all your dreams are reruns (重演)．”

The very successful head of the Chrysler Corporation，Lee Iacocca，used to ask his workers，“What do you want to do？What do you want to be？What do you want to have？Where do you want to go？How do you plan to get there？Write it down.Now go to do it.It doesn't get any simpler or better than that.”

So why not start living your life on purpose？First dream it，and then do it.They say that one hour of planning will save you three hours of wasted time and work.With a plan，your work is working for you.Your plan will keep you in control of your life，moving ahead toward your goal of success and happiness.

After you plan your work，you have to make your plan work.Discipline is what brings your dreams into real life.A dream with no discipline will just remain a dream，and a plan without work will be a plan that won't work.

(2017·无锡高三期末考试)Most evenings，before watching late-night comedy or reading emails on his phone，Matt Nicoletti puts on a pair of orange-colored glasses that he bought for $8 on the Internet.

“My girlfriend thinks I look ridiculous in them，” he said.But Mr.Nicoletti，a 30-year-old consultant in Denver，insists that the glasses，which can block certain wavelengths of light emitted by electronic screens，make it easier to sleep.

Studies have shown that such light，especially from the blue part of the spectrum (光谱)，inhibits the body's production of melatonin(褪黑激素)，which helps people fall asleep.Options are growing for blocking blue light，though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night.

A Swiss study of 13 teenage boys，published in August in The Journal of Adolescent Health.showed that when the boys wore orange-colored glasses，also known as “blue blockers” and shown to prevent melatonin，in the evening for a week，they felt “significantly more sleepy” than when they wore clear glasses.The boys looked at their screens，as teenagers tend to do，for at least a few hours on average before going to bed，and were monitored in the lab.

Older adults may be less affected by blue light，experts say，but blue light remains a problem for most people，and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses，which blocked only ultraviolet(紫外线)light.

LEDs used in devices such as smart phones，tablets and televisions tend to emit more blue light than incandescent products(白炽产品)．LEDs are also increasingly popular as room lights，but “warm white” bulbs，with less blue，tend to be a better choice than “cool white” for nighttime use.The lighting company Philips also makes a reduced－blue LED bulb，meant to be used before bedtime.“In theory，anything that will decrease that blue light exposure at night will be helpful.” said Christopher Colwell，a scientist at the UCLA，“I know some gainers who swear by those orange-colored glasses.”

But orange glasses are not a panacea(万能药)．Dr.Skene said.“It isn't just getting rid of the blue and everything's fine，” she said.The intensity of light，in addition to color，can affect sleep，she said，and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep.

During the daytime，experts say，exposure to blue light is good.Best of all is sunlight，which contains many different wavelengths of light.“That's what our brain knows，” said Kenneth P．Wright Jr.，director of the sleep and chronobiology(生物钟学)lab at the University of Colorado，Boulder.

A 2013 study he led，published in the journal Current Biology，showed just how different things can be without nighttime lights.After participants had camped in the mountains for a week，their bodies began to prepare for sleep about two hours earlier than normal.

Short of cutting out all evening electronics，experts say，it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device.

“If you can look at the iPhone for 10 minutes rather than three hours，that makes a lot of difference，” Dr.Skene said.
