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 people 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, the people 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 subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. People 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 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 sleep patterns observed all night |
| C．read a paper book and an iPad at the same time |
| D．have their blood tested per hour during the trial |
The third paragraph tells us the iPad readers were likely to____________.
| A．feel less sleepy and tired in the day |
| B．fall asleep more easily after reading |
| C．become less energetic the next morning |
| D．have a lot more melatonin secretion |
The special software recently developed can______.
| A．remove the blue light from your devices completely |
| B．help prevent eyes being harmed by short wavelength |
| C．weaken the harm done by doing nighttime e-reading |
| D．be used in all the e-things widely and safely |
Which of the following can be the best title for the text?
| A．No e-reading in bed before sleep |
| B．New software for night e-readers |
| C．Wrong behaviors before bedtime |
| D．No games on iPad in bed |
Computers are very important to modern life．Many people think that in the future computers will be used in lots of everyday life．It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet．There will be no more books because we will be able to get all texts from computers．The Internet will be used to play games, see films and buy food．Most telephone calls will be made by computers, too．

While many people say it is a pleasure to go into shops and look at things you want to buy．It is also unlikely that many people will want to read large texts on our computers.

Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat（闲谈）with friends—you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout of appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you.

Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor （酒精饮料）by using fake identification (伪造证件).

Parents can also help set a good example by not drinking and driving. They can have firm rules in the home that everyone follows.
Give the children good ideas on how to say “no” to drinking, even when they are at a party. Try not to overreact or panic (惊慌) if the child tries alcohol. How you handle it can affect their attitude.

I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed（解散）. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized（强调） the fact that when people do something dishonest, they are really cheating（欺骗） themselves. She made me promise that I would think seriously（认真地） about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued（继续） to believe that I had cheated on the test.The story took place（发生） exactly ____ .

Some people bring out the best in you in a way that you might never have fully realized on your own.My mom was one of those people.
My father died when I was nine months old,making my mom a single mother at the age of eighteen.While I was growing up,we lived a very hard life.We had little money,but my mom gave me a lot of love.Each night,she sat me on her lap and spoke the words that would change my life,“Kemmons,you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen,I was hit by a car and the doctors said I would never walk again.Every day,my mother spoke to me in her gentle,loving voice,telling me that no matter what those doctors said,I could walk again if I wanted to badly enough.She drove that message so deep into my heart that I finally believed her.A year later,I returned to school—walking on my own!
When the Great Depression(大萧条)hit,my mom lost her job.Then I left school to support the both of us.At that moment,I was determined never to be poor again.
Over the years,I experienced various levels of business success.But the real turning point occurred on a vacation I took with my wife and five kids in 1951.I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child.That was too expensive for the average American family.I told my wife that I was going to open a motel(汽车旅馆)for families that would never charge extra for children.There were plenty of doubters at that time.
Not surprisingly,mom was one of my strongest supporters.She worked behind the desk and even designed the room style.As in any business,we experienced a lot of challenges.But with my mother’s words deeply rooted in my soul,I never doubted we would succeed.Fifteen years later,we had the largest hotel system in the world—Holiday Inn.In 1979 my company had 1759 inns in more than fifty countries with an income of $1 billion a year.
