Some people can stay up all night and still get work done the next day.I'm not one of them.After a night without enough sleep, I feel badtempered.I have trouble remembering things.And all I want to do is to crawl into bed and sleep.
How do you feel after you've stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” affects how well you function without sleep.The “period 3” gene comes in two forms：short and long.Everyone has two copies of the gene.So, you may have two longs, two shorts, or one of each.Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”．Study participants had to stay awake 40 hours straight.Then，they took tests that measured how quickly they pushed a button when numbers flashed on screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did.In both groups，people performed worst in the early morning.
After the first round of experiments，participants were finally allowed to sleep.People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
People with the long “period 3” gene, by contrast, fell asleep in just 8 minutes.They also spent more time on deep sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of“period 3”．What about you?
1.The purpose of this passage might be________.
A．to tell us the importance of plenty of sleep
B．to tell the result of a research on sleepy gene
C．to inform the harm of lacking sleep
D．to announce the sleeping rules of humans
2.Which of the following decides how well you perform without sleep?
A．One short form.
B．One long copy.
C．One short and two long copies.
D．Period 3.
3.What kind of people need less sleep according to the research?
A．Those with two long copies of the gene.
B．Those with two short copies of the gene.
C．Those with one short and one long copy of the gene.
D．Those with three short copies of the gene.
4.If one lacks enough sleep，one should avoid doing important or dangerous things

Is Fresh Air Really Good for You?
We all grew up hearing people tell us to “go out and get some fresh air.” 1. According to recent studies, the answer is a big YES, if the air quality in your camping area is good.
2. If the air you’re breathing is clean—which it would be if you’re away from the smog of cities—then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.
Recently, people have begun studying the connection between the natural world and healing(治愈). 3. In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 4. It gives us a great feeling of peace.
5.While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D . To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D .
A.Fresh air cleans our lungs.
B.So what are you waiting for?
C.Being in nature refreshes us.
D.Another side benefit of getting fresh air is sunlight.
E.But is fresh air really as good for you as your mother always said?
F.Just as importantly, we tend to associate air with health care.
G.All across the country, recovery centers have begun building Healing Gardens.

Life is kind of like a party. You invite a lot of people, some leave early, some stay all night, some laugh with you, some laugh at you, and some show up really late. But in the end, after the fun, there are a few who stay to help you clean up the mess. And most of the time, they aren’t even the ones who made the mess. 1. They are the ones who matter most. Here are four things real friends do differently:
They face problems together. A real friend is someone who sees the pain in your eyes while everyone else still believes the smile on your face. 2. Just look for someone who will face them with you.
3. Your word means everything. If you say you’re going to do something, DO IT! If you say you’re going to be somewhere, BE THERE! If you say you feel something, MEAN IT! If you can’t, won’t, and don’t, then DON’T LIE. Real friends keep promises and tell the truth upfront.
They accept each other. Trying to change a person never works. A real friend is someone who truly knows you and loves you just the same. 4. Be yourself and people will love the real you. If you feel like changing something about your friend, ask yourself what change you can make in yourself instead.
They support each other’s growth changes. Our needs change with time. When someone says, “You’ve changed,” it’s not always a bad thing. 5.Don’t apologize for it. Instead, be open and sincere, explain how you feel, and keep doing what you know in your heart is right,
A. They keep their promises.
B. No one is happy all the time.
C. They make time for each other.
D. Don’t change so that people will like you.
E. Sometimes it just means you’ve grown.
F. These people are your real friends in life.
G. Don’t look for someone who will solve all your problems.

The stereotype(固有观念)of computer scientists as nerds who stay up all night coding and have no social life may be driving women away from the field, according to a new study published this month. This stereotype can be brought to mind based only on the appearance of the environment in a classroom or an office.
“When people think of computer science the image that immediately pops into many of their minds is about the computer geek(怪人)surrounded by such things as computer games, science fiction and junk food,”said Sapna Cheryan, a University of Washington assistant professor of psychology and the study’s lead author. “That stereotype doesn’t appeal to many women who don’t like the portrait of masculinity(男性化).”
Cheryan set up four experiments involving more than 250 female and male students who were not studying computer science to look at possible reasons why the proportion of women in the field is dropping while the proportion of women in such disciplines as biology, mathematics and chemistry is increasing.
In the first experiment,students entered a small classroom that either contained objects stereotypically associated with computer science such as Star Trek posters, video game boxes and Coke cans, or non-stereotypical items such as nature posters, art, a dictionary and coffee cups. The students were told to ignore these objects because the room was being shared with another class. After spending several moments in the classroom, the students filled out questionnaires(调查问卷)that asked about their attitude toward computer science.
Women exposed to the stereotypical setup expressed less interest in computer science than those who saw the non-stereotypical objects. Men placed in the same situations did not show a similar drop in interest in computer science. Cheryan said this study suggests that a student’s choice of classes or a major can be influenced by the appearance of classrooms, halls and offices.
1. The underlined word “nerds” in Paragraph 1 probably refers to “______”
A. dull persons B. active persons C. intelligent persons D. funny persons
2. Women are less likely to choose computer science because__________.
A. it is too difficult for them
B. they have wrong understanding of it
C. the lifestyle of computer scientists turns them away
D. they don’t like the social life of computer scientists
3. A woman would probably lose interest in computer science when she sees a ______.
A. Star Trek poster B. nature poster C. dictionary D. coffee cup
4. What can influence a woman’s choice of classes, according to the passage?
A. The contents of computer science.
B. The space in the classroom.
C. The number of students in the classroom.
D. The classroom environment.

I can still remember it as if it happened yesterday. I was a college freshman and had stayed up most of the night before laughing and talking with friends. Now just before my first class of the day my eyelids were feeling heavier and heavier and my head was drifting down to my desk to make my textbook a pillow. A few minutes’ nap time before class couldn’t hurt, I thought.
Boom! I lifted my head immediately and my eyes opened wider than saucers. I looked around with my heart beating quickly trying to find the cause of the noise. My young professor was looking back at me with a mischievous, boyish smile on his face. He had intentionally dropped the pile of textbooks he was carrying onto my desk. “Good morning!” he said, still smiling. “I’m glad to see everyone is awake. Now let’s get started.”
For the next hour I wasn’t sleepy at all. It wasn’t from the shock of my professor’s textbook alarm clock either. Instead, it was from the attractive discussion he led. With knowledge and good humor, he made the material come alive. His insights were full of both wisdom and loving kindness. And the enthusiasm and joy that he taught with were contagious (有感染力的). I left the classroom not only wide awake, but a little smarter and a little better as well.
I learned something far more important than not sleeping in class that day too. I learned that if you are going to do something in this life, do it well, do it with joy, and make it an expression of your love. What a glorious place this world would be if all of us did our work joyously and well! What a beautiful world we could create if every doctor, teacher, musician, cook, waitress, poet, miner, farmer, and laborer made their work an expression of their love! Don’t sleepwalk your way through life then. Wake up! Let your love fill your work and your soul. Life is too short not to live it well.
1.What did the author want to do just before his first class of the day?
A. Take a short sleep. B. Talk with his friends.
C. Get his eyes examined. D. Stay away from the class.
2.The underlined word “mischievous” in Paragraph 2 probably means “________”.
A. curious B. naughty
C. sensitive D. dishonest
3.What else did the author learn that day?
A. Students should not sleep in class but respect their teachers.
B. Everyone should love his job and sleepwalk his way through life.
C. People from all walks of life should do their jobs with wisdom and love.
D. Life is too limited to make your work an expression of your love.
4.What can be inferred from this passage?
A. The professor often kept his students sharp by using a textbook alarm.
B. The author left the two-hour period not only wide awake, but a little smarter.
C. The author was attracted by the professor’s great wisdom and enthusiasm.
D. Though the author was frightened awake, he was not clear-headed in the class.
