The bed should be reserved as a place for sleep, but people tend to read an iPad a lot in bed before they go to sleep.
Charles Czeisler, a professor at Harvard Medical School, and his colleagues got a small group of people for an experiment. For five days in a row, the subjects (实验对象) read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, they took hourly blood tests to paint a day-long picture of just how much melatonin (褪黑激素) was in their blood at any given time.
When the subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. They also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion (分泌) was delayed by an hour and a half.
The researchers conclude in today's journal article that given (考虑到)the rise of e-readers and the increasingly widespread use of e-things among children and adolescents, more research into the long-term consequences of these devices on health and safety is urgently needed. Czeisler and colleagues go on, in the research paper, to note：“Reading an iPad in bed may increase cancer risk.”
However, software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day, and there are also glasses that are made to filter (过滤) short wavelengths. While they seem like a logical solution for the nighttime tech users, it needs more research.In Charles Czeislers experiment, all the subjects were asked to______.
| A．sit in a row and receive the strict tests |
| B．have their blood tested per hour during the trial |
| C．read a paper book and an iPad at the same time |
| D．have their sleep patterns observed all night |
The third paragraph tells us the iPad readers were likely to______.
| A．feel less sleepy and tired in the day |

| A．weaken the harm done by doing nighttime e-reading |
| B．help prevent eyes being harmed by short wavelength |
| C．remove the blue light from your devices completely |
| D．be used in all the e-things widely and safely |

Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you’ll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’eyes，and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge，it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind’s picture of yourself. This image includes the way you look，the way you act，the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is，make a list if you need to，but write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile,get to the track and practice. If you think you’re dull because you don’t wear the latest trends，buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative self-image is to realize that your image is far from objective，and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back，you’ll know you're well on your way. Good luck!You need to build a positive self-image when you___________.

Recipients（接受者）of this year's Annenberg scholarships were announced on June 19. Brittany Blythe was one of them.
In seventh grade，Brittany Blythe dreamed of being a cheerleader（啦啦队队员）. Her school’s coaches were less than enthusiastic. “They said. ‘I don't know how you’ll be able to do it’. ”she recalls. “‘You won’t be able to do it’.”
But Brittany，now a junior at Strath Haven High School near Philadelphia，refused to give up. And when the junior school cheerleaders won a tournament last year, she was right there，dancing and cheering with the rest of the team.
Not bad for someone whose legs were cut off below the knee when she was two years old.
Brittany,18,was born without shinbones(胫骨）—“just blood and muscle tissue，”as she puts it. When she tried to walk, her legs twisted.
After the operation, she adapted quickly. “From day one，I basically jumped up and wanted to do everything,’’ she says. Prostheses(假肢)allowed her to move around upright. But too slowly to keep up with her friends. Brittany’s solution was to take the legs off and walk on her knees something she still does when safety and comfort permit.
She has been rarely discouraged. Other children laughed at her through the years，especially in junior high school，but she says the challenge only made her stronger. Now she’s trying to convince her coaches to let her remove the prostheses and be a flyer. The cheerleader who's thrown in the air and caught by her teammates.
Brittany doesn’t think her problems put her at a disadvantage. “My disability was the first thing I had to get through., and that’s going to prepare me for the future. ”she says. “It’s all just a test：If someone throws you a difficult problem，what are you going to do?” What was the coaches’ first attitude towards Brittany's dream?

Federal regulators Wednesday approved a plan to create a nationwide emergency alert（警报）system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years，particularly among young people.The wireless industry’s trade association, CTIA，estimates（估计）more than 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act，a 2006 federal law that requires improvement to the nation's emergency alert system.The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.
“The ability to deliver accurate and timely warnings.and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public.has the information they need to take action to protect themselves and their families before, and during,disasters and other emergencies. ”FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers—telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages，according to the rules.
The first would be a national alert from the president，likely involving a terrorist attack or natural disaster.The second would involve “approaching threats，”which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction（绑架）emergencies,or so-called Amber Alerts.
The service could be in place by 2010. What is the purpose of the approved plan?
| A．To warn people of emergencies via messages. |
| B．To popularize the use of cell phones. |
| C．To estimate the monthly number of messages. |
| D．To promote the wireless industry. |
The improvement to the present system is in the charge of ________.
| A．CTIA | B．the Warning Alert and Response Network |
| C．FCC | D．federal regulators |

While reading a story on 20-somethings complaining about how the economy was ruiningg their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled who grew up expecting everything to be easy for them. As a 20-something myself, certainly share their disappointment : my husband and I probably won’t be able to buy a house until we’re in our 40s, and we two are burdened by student loans(贷款). But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?
Consider some of these views shared in the story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.
I read that, and I thought what planet she is living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢华), not a fertility requirement.
A 26-year-old in the story is disappointed that he can’t afford to get a Ph. D in literature. Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.
Yes, it’s sad that these young people feel so lost. But I think the problem is their extremely high expectations, not economic reality. Beth Kobliner, author of Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations grew up at a time when everyone’s wealth appeared to be increasing, Their parents probably saw their home values rise along with their investments. “So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.
This recession(经济衰退) will certainly play a role in forcing those expectations into more realistic group. In the meantime, it seems a lot better for our mental health to focus on being grateful---for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day---than on longing for some kind of luxury life. .

| A．They expect everything to be easy for them. |

| C．They are unwilling to face all of the challenges. |
| D．They are burdened by student loans. |
. The underlined word “fertility” in paragraph 3 probably means“_____”.

| A．They can’t have children for at least a decade a decade to buy a house. |
| B．They have only a one-bedroom apartment to live in. |
| C．They can’t buy a house until 40 and are burdened by student loans. |
| D．They despair at not being able to afford a PH. D in literature. |
. What’s the Kobliner’s attitude towards the 20-somethings with high expectations?

I’ve changed my mind. “ I wanted to have a telescope, but now I want my dad back.” Lucien Lawrence’s letter to father for Christmas written after his schoolteacher’s father had been knifed to death outside his school gate, must have touched everyone’s heart. Lucien went on to say that without his father he couldn’t see the stars in the sky. When those whom we love depart from us, we cannot see the stars for a while.
But Lucien, the stars are still there, and one day, when you are older and your tears have gone, you will see them again. And, in a strange way, I expect that you will find your father there too, either in your mind and heart. I find that my parents, who died years ago, still figure in many of my dreams and that I think of them perhaps more than I ever did when they were alive. I still live to please them and I’m still surprised by their reactions. I remember that when I became a professor, I was so proud, or rather so pleased with myself that I couldn’t wait to cable my parents. The reply was a long time in coming, but when it did, all my mother said was “ I hope this means that now you will have more time for the children!” I haven’t forgotten. The values of my parents still live on.
It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care. Would I have been as ready as Philip Lawrence have been to face the aggressors, and to lay down my life for those in my care? How many people would want me back for Christmas? It’s a serious thought, one to give me pause.
I pray silently, sometimes, in the dead of night, that ancient cry of a poet “Deliver my soul from the sword, and my darling from the power of the dog.” Yet I know the death comes to us all, and sometimes comes suddenly. We must therefore plan to live forever, but live as if we will die tomorrow. We live on, I’m sure, in the lives of those we loved, and therefore we ought to have a care for what they will remember and what they will treasure. If more parents knew this in their hearts to be true, there might be fewer knives on our streets today. . According to the whole text we can see that the first paragraph ________.
