Lights Out at Bedtime
There are plenty of good reasons to power up a personal desktop or laptop computer in the evening — writing e-mails，chatting on social networks or making purchases over the Internet，for instance．But various studies indicate that people who stare at a PC’s bright monitor shortly before going to bed probably sleep less soundly than they would otherwise because the light seriously affects their natural wake-sleep cycle．"They haven't proved it though，" says Dieter Kunz，the team's director at Charite's Psychiatric Clinic in St．Hedwig's Hospital in Berlin．
Similarly，exposure to just 10 minutes of normal bathroom lighting is enough to free the sleep hormone melatonin，which regulates people's natural wake-sleep cycle and makes them sleepy at nightfall．
Ten years ago，a team of British and American researchers detected a photo-pigment（光敏色素） in the human eye that signals to the body whether it is day or night，summer or winter．The photo-pigment is especially sensitive to blue light．
"The blue light more or less tells the body，It's daytime，be awake，'" Kunz says．Monitors have a mostly cold white light content and scientists suspect the photo-pigment may react similarly to it．So the longer people look into the bright light，the more awake they become - and then sleep poorly．
A lot of people have difficulty "switching off" in the evening．About half of the women in Germany and a quarter of the men sleep poorly．
Environmental factors are only one of the possible causes．Job stress as well as personal and health concerns are also the main reasons for their sleep problems．
In addition，electronic objects' standby lights and indicator lamps can be annoying in the dark and affect sleep．"Sound scientific evidence is still lacking on this matter，" Kunz notes．
According to Kunz，those who cannot go without their computer in the evening should turn down the blue content if possible and lower the brightness somewhat．"But nobody does that because，after all，you want to concentrate while working at the computer and the light helps the brain．"
The passage is mainly about ____________．

A．natural wake-up cycles

B．the effect of light on sleep

D．functions of computer monitors

The underlined word “which” in Paragraph 2 refers to_____．

A．normal bathroom lighting

B．10-minute exposure to lighting

A．the blue light has a calming effect．

B．the photo-pigment tells people day or night

C．women in Germany use computers more often than men

D．it has been proved that standby lights affect people’s sleep

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
I had to knock on the taxi to get his attention．Finally，the driver，a man about 60，looked up from behind the wheel and apologized，“I’m sorry，but I was reading a letter．” He sounded as if he had a cold or a cough．
Since I was in no hurry，I told him to finish his letter．He shook his head，explaining that he had already read it several times and almost knew it by heart．Curious，I asked whether it was from a child or maybe a grandchild． “This isn’t family，”he replied． “though he might just as well have been a regular member of the family．Old Edand I grew up together．”
They were always friends．But since he moved away from the neighborhood 30 years ago，it’d generally just been postcards at Christmas time between them．A couple of weeks ago，Ed died． “I should have kept in touch．” He repeated this，more to himself than to me．To comfort him，I said sometimes we just didn’t seem to find the time．“But we used to find the time，” he said． “Take a look．” He handed the letter over to me．
The first sentence “I’ve been meaning to write for some time，but I’ve always delayed it．” reminded me of myself．It went on to say that he often thought about the good times they had had together．When I read the part where it said “Your friendship really means a lot to me，more than I can say because I’m not good at saying things like that”，I found myself nodding in agreement．
We had gone several kilometers and were almost at my hotel, so I read the last paragraph: “So I thought you’d like to know that I was thinking of you.” And it was ended with “Your Old Friend, Tom.”
“I thought your friend’s name was Ed,” I said.
“I’m Tom,” he explained. “It’s a letter I wrote to Ed before I knew he’d died. I never put it in the mailbox. I guess I should have written it sooner.” His face was pale as he wiped his eyes with a handkerchief.
When I got to my hotel room I didn’t unpack right away．I had to write a letter and post it．
Who wrote the letter？
A． Tom
B． Old ED．
C． The author．
D． The driver’s grandchild．
It can be inferred from the passage that the driver regretted_____．

A．missing Ed’s funeral

B．moving away from his neighborhood

When I heard the piano, I walked to Mrs. Windsor’s house and waited outside as I always did. That meant she was working with another student, and I was not supposed to bother them by ringing the bell. I stood against the wall and daydreamed what I’d rather be doing. “Almost anything”, I sighed dejectedly. I had been tutored enough to read, understand, and even write some musical compositions, but I just didn’t have a gift for it. It didn’t come to me naturally. I thought back to happier times when I was writing stories and acting them out with my friends, cutting up old clothes to make dresses that performers wear in plays, and building scenery out of old things we found. But Mrs. Windsor had offered to give me the lessons for free, so I felt my duty to try.
The door opened and Wendy Barton came out. I walked in, sat down on the piano bench and began to sort through my sheet music.
“Hello,” I heard a voice behind me say softly. I turned around to see a little girl standing behind me, eating an apple. But before I could make any response, Mrs. Windsor walked into the room in her usual urgent manner and announced,“Jennifer, this is my niece, Pasha. Pasha, this is Jennifer. Pasha will be giving you your lesson today. I’m up to my ears in something else!” she then exited to the kitchen.
Pasha set her apple down on the side table and slid beside me on the piano bench.
“What piece do you like best?”she asked.
“What do you mean?” I asked. “They’re all the same to me. I don’t know.
“You mean you don’t have a favorite?”
“No, not really.”
Pasha looked at me, rather puzzled, then opened my sheet music to the beginning page and asked me to play. I arranged my fingers on the keys and studied the notes on the page for a moment. Then I frowned and concentrated to make the notes on the page match the finger movements. I have to admit I was a rather mechanical pianist.
After about a page or two, Pasha gently put her hand on top of mine as if to calm my fingers. There was a long pause. “What are you hearing in the music?” I looked at her rather strangely and admitted I didn’t know what she meant.
“Like a story. What story is being playing out within the music?”
“I guess I’ve never thought about it before. I don’t know.”
“Here, let me try and you listen,” Pasha advised.
She closed her eyes and took a deep breath, letting her fingers dance lightly over the keys. Then, she began to play. “See, it begins here beside some kind of river. Hear the water flowing beside you?”
Her fingers rose and fell gently on the keys.“Now the princess appears and she’s picking flowers from the water’s edge.”A carefree, happy piece of music filled the air in time to Pasha’s dancing fingers. “Oh, but she slips!”The music changed. “And our princess is being carried off by the fast-flowing stream. Quickly, the princess’s horse sees her plight (困境),” Pasha continued, and races to the river’s edge where he swims out to let her catch hold of him. They make it to the bank and she hugs her faithful horse and swears she will never again wear princess skirts that weigh her down. She will only wear jeans and T-shirt from now on.” Pasha finished with a big smile and then looked at me.
“Aren’t you the girl who tells the stories?” she asked.
“I guess. I do tell a lot of stories.”
“Oh, yes! All the kids talk about them. I’ve heard about you. Well, all you have to do is learn to hear the stories in the music. That’s all there is to it.”
“I’ve never thought it that way.”
“Let’s try another one, shall we?”Pasha smiled and together we played that afternoon, finding the stories in the music and learning that sometimes it takes a friend to pull you out of the river onto dry land again.

The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past. With the coming of new technologies like computers and smartphone, writing by hand has become something of nostalgic (怀旧的)skill. However, while today’s educators are using more and more technology in their teaching, many believe basic handwriting skills are still necessary for students to be successful---both in school and in life.
Virginia Berninger, professor of educational psychology at the University of Washington, says it’s important to continue teaching handwriting and help children acquire the skill of writing by hand.
Berninger and her colleagues conducted a study that looked at the ability of students to complete various writing tasks---both on a computer and by hand. The study, published in 2009, found that when writing with a pen and paper, participants wrote longer essays and more complete sentences and had a faster word production rate.
In a more recent study, Berninger looked at what role spelling plays in a student’s writing skills and found that how well children spell is tied to know well they can write. “Spelling makes some of the thinking parts of the brain active which helps us access our vocabulary, word meaning and concepts. It is allowing our written language to connect with ideas.” Berninger said.
Spelling helps students translate ideas into words in their mind first and then to transcribe “those words in the mind written symbols on paper or keyboard and screen,” the study said. Seeing the words in the “mind’s eye” helps children not only to turn their ideas into words, says Berninger, but also to spot spelling mistakes when they write the words down and to correct then over time.
“In our computer age, some people believe that we don’t have to teach spelling because we have spell checks,” she said. “But until a child has a functional spelling ability of about a fifth grade level, they won’t have the knowledge to choose the correct spelling among the options given by the computer.”

D．discussed the importance of writing speed.

Which of the following best shows the role of spelling?

A．Spelling improves one’s memory of words.

B．Spelling ability is closely related to writing ability.

C．Spelling benefits the translation from words into ideas.

D．Spelling slows down finding exact words to express ideas.

What does “mind’s eye” in paragraph 5 mean?

A．Window.	B．Soul
C．Picture.	D．Imagination.

A．Computers can help people with their choice of words.

B．Spell checks can take the place of spelling teaching.

C．Handwriting still has a place in today’s classrooms.

D．Functional spelling ability develops fast in the fifth grade.

You're not doomed to toss and turn every night. Although you might not be able to control all of the factors that relate to your sleep, you can adopt habits that encourage better sleep. Start with these simple sleep tips.
No. 1: Stick to a sleep schedule
Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces （加强） your body's sleep-wake cycle and helps promote better sleep at night. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired.
No. 2: Pay attention to what you eat and drink
Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet. Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine — which take hours to wear off — can ruin quality sleep.
No. 3: Create a bedtime ritual
Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to light music. Be careful of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime has impact on sleep.
No. 4: Get comfortable
Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.
Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you have children or pets, set limits on how often they sleep with you — or insist on separate sleeping quarters.
No. 5: Limit daytime naps
Long daytime naps can affect nighttime sleep — especially if you're struggling with poor sleep quality at night. If you choose to nap during the day, limit yourself to about 10 to 30 minutes and make it during the mid-afternoon.
If you work nights, you'll need to make an exception to the rules about daytime sleeping. In this case, keep your window coverings closed so that sunlight — which adjusts your internal clock — doesn't interrupt your daytime sleep.
No. 6: Include physical activity in your daily routine
Regular physical activity can promote better sleep, helping you to fall asleep faster and to enjoy deeper sleep. Timing is important, though. If you exercise too close to bedtime, you might be too energized to fall asleep. If this seems to be an issue for you, exercise earlier in the day.
No. 7: Manage stress
When you have too much to do — and too much to think about — your sleep is likely to suffer. To help restore peace to your life, consider healthy ways to manage stress. Start with the basics, such as getting organized, setting priorities and dividing tasks. Give yourself permission to take a break when you need one. Share a good laugh with an old friend.
Nearly everyone has an occasional sleepless night — but if you often have trouble sleeping, contact your doctor. Identifying and treating any underlying causes can help you get the better sleep you deserve.
