8．不知道你是否介意我们问几个问题？（mind sb/sb's doing）Would you mind us/our asking several questions？．

7．These days，many of us use computers both at work and at home．We use them to do a number of different things，from typing documents to surfing the Internet and listening to music．However，it is important to remember that using a computer for long hours can cause harm to our bodies．Here are some tips to help keep you healthy when using a computer．
Take care of your back
Make sure your chair is the right height and size for you and the desk you use．Your desk should be at about the same level as your elbows when you are sitting down．Chairs with armrests are good because they allow you to rest your arms．Do not lean forward over the keyboard towards the screen because this is bad for your back．Sit upright，with your feet touching the ground and your back resting on the back of the chair．Doing these things will help you prevent back-related problems such as pain in your neck，shoulders and arms．
Take care of your wrists and hands
Using a keyboard and a mouse can put pressure on your wrists and hands if it is not done properly．When you type，try to make sure your fingers are relaxed．You should hit the keys softly and hold the mouse gently．Mouse mats that come with soft material to support your wrist are really good too．Pain in the hands and wrists is very common among people who use computers a lot，so make sure you use your mouse and keyboard in the right way．
Take care of your eyes
Your eyes are very important and it is necessary to take care of them．You should give them regular breaks from staring at the computer screen．Every fifteen minutes，rest your eye muscles by looking away from the screen at something far away．Make sure that the top of your monitor is at eye level and that your monitor is about an arm's length away from you．
Take a break
It is important that you do not sit at a computer for too long．No matter how busy you are，try to take regular breaks from your desk．Stand up，go for a short walk or even do some stretching exercises．You should take a short break at least once an hour，and you should try to do some stretching exercises every two hours．By following all these tips，you will not feel so tired after using your computer for a long time．

6．Many people think that a job or a workplace is the only cause of stress．This is not completely true．Stress can be experienced anywhere and its cause can be anything．But when you go home，you should be able to let go all your stress and relax．The following should help you deal with stress at home．
Many people are not able to deal with stress because they simply don't know about the cause of their stress．Are your goals too high？Are you able to meet the demands of your family？Is everything between you and your friends all right？These are some of the many questions that you need to ask yourself．Even the simplest issues，such as traveling a great distance to your workplace，can cause a lot of stress．
Knowing the cause is very important and it is the first step in dealing with stress．
You also need to find the best way that suits you．Sometimes a bad memory or an incident that
happened in the past may worry you．You can always try meditation（沉思）to deal with such emotional
problems．The simplest of all relaxation techniques is to lie down on a bed and close your eyes．Try not to think of anything．
If you have a hobby，then dealing with stress becomes easier．A hobby not only helps you to get away from a stressful environment，but also gives you energy to deal with difficult situations．
More often than not you are unable to deal with a situation because you do not organize yourself．
Your actions are out of order because you are confused in your thoughts．Well，this may be because you are a little bit inexperienced．Try to think clearly．Write down the things that are troubling you or the things that you need to do．Make an efficient（有效的）plan to deal with them at home．A practical action plan solves almost all the problems that you can have．

5．My mother has never beaten my sisters and brothers，and me only once．She found effective ways of punishment that left a more  （11）B memory than the short pain of a beating．One of the most（12）Coccasions occurred when I was four．
One day my mother（13）Aearly from the kindergarten because we were going shopping for Christmas．I was（14）D at the sight of the lights and decorations，and as we walked through the doll section in the supermarket，I saw a doll I must have．Looking lovingly（15）B at my mother，I asked，"Mama，can I have that doll？"
She（16）A，"Baby，not now，but if you are a good girl maybe （17）C will bring it to you．""But Mama，I want that doll right now．"Her eyes（18）Aand her hand tightened on mine．"Becky，you can't have that doll today，but if you（19）B you can have a spanking（打屁股）．"
I immediately （20）Don the ground and began screaming，"I want that doll，"over and over again．Christmas shoppers looked （21）C my mother calmly said，"Becky，you better get up by the（22）A of three or else．One…Two…Three．"
Nothing．I was still in full（23）C．So then she lay down beside me on the floor，and began kicking and screaming like I did，"I want a new car，I want a new house，I want some jewelry，I want…"（24）D，I stood up．
"Mama，stop．Mama，get up，"I tearfully （25）B．
She stood，and（26）Cdust off herself．At first surprised，the customers waiting in line began to clap，and before I knew it they were （27）Aand laughing and patting my mother on her back．She went red and took a little bow．The next thirty minutes was a（an） （28）Cfor me because so many parents leaving the supermarket，（29）D their heads at me and said with a smile，"Your mom got you good．I bet you'll never try that again．"
And I didn't，because it left a lasting mental picture more  （30）Athan any physical mark．

4．The was a wonderful old man who loved almost everything，animals，spiders，insects …One day，while walking through the woods，the nice man found a cocoon （茧） of a butterfly．He decided to take the cocoon home to watch its magic process of （21）Bfrom a little cocoon into a butterfly．He （22）Aplaced the cocoon on his kitchen table and （23）Bit for days．One day the cocoon started to move，a small （24）C appeared．The old man sat beside it and watched as the butterfly inside struggled for several hours to （25）Dits body through the little hole．
（26）C，the butterfly seemed to stop making any progress．It appeared as if it had gotten （27）Bit could and it could go no farther．The old man felt （28）A for the little butterfly inside so he decided to help the little （29）D．He took a pair of scissors and cut the remaining bit of cocoon open．The butterfly then came out easily，but it had a （30）Abody and small，shriveled （枯萎的） wings．
The man continued to watch the butterfly because he expected that，（31）C，the wings would expand and be able to （32）D the body，which would slim down in time．Neither happened!（33）A，the butterfly spent the rest of its life crawling around with an unusually fat body and shriveled wings．It never was able to fly．
What the man，in his （34）B and eagerness，did not understand was that the restricting cocoon and the struggle （35）Dto get through the tiny opening were nature's way of forcing fluid （液体） from the body of the butterfly into its wings（36）C it would be ready for flight once it achieved freedom．
Sometimes （37）Dare exactly what we need in our life．If nature allowed us to（38）A life without hardships or obstacles，it would weaken or even damage us over time both physically and mentally．We would not be as （39）B as we could have been．Give every opportunity a chance，leave no room for （40）C．have a great day，great life，and struggle a little．Then fly!

3．One student skipped class and then sent the professor an e-mail（50）Dfor copies of her teaching notes．
Another（51）Cthat she was late for a Monday class because she was recovering from drinking too much at a wild weekend party．
At colleges and universities in the US，e-mail has made professors more approachable（平易近人）．But many say it has made them too accessible，（52）Aboundaries that traditionally kept students at a healthy distance．
These days，professors say，students seem to view them as available（53）Bthe clock，sending a steady stream of informal e-mails．
"The tone that they take in e-mails is pretty astounding（令人吃惊的），"said Michael Kessler，an assistant dean at Georgetown University．"They'll（54）Cyou to help：‘I need to know this．'"
"There's a fine（55）Dbetween meeting their needs and at the same time maintaining a level of legitimacy（正统性）as an （56）Bwho is in charge．"
Christopher Dede，a professor at the Harvard Graduate School of Education，said（57）Ashow that students no longer defer to（听从）their professors，perhaps because they realize  that professors'（58）Bcould rapidly become outdated．
"The deference （听从）was driven by the （59）Cthat professors were all-knowing sources of deep knowledge，"Dede said，and that notion has（60）B．
For junior faculty members（全体教师），e-mails bring new tension into their work，some say，as they struggle with how to（61）C．Their job prospects，they realize，may rest in part on（依赖） student evaluations of their accessibility．
College students say e-mail makes（62）Deasier to ask questions and helps them learn．But they seem unaware that what they write in e-mails could have negative effects（63）Athem，said Alexandra Lahav，and associate professor of Law at the University of Connecticut．She recalled an e-mail message from a student saying that he planned to miss class so he could play with his son．Professor Lahav did not respond．
"Such e-mails can have consequences，"she said．"Students don't understand that （64）Dthey say in e-mail can make them seem unprofessional，and could result in a bad recommendation．"

2．In America，drivers'education is part of the regular high school curriculum．Every student in his or her second year of high school is required to （1）B a class in drivers'education．
However，unlike other （2）D，it is not given during the （3）C school year．Instead it is a summer course．The course is divided up into two parts：class time for learning laws and （4）B and driving time to practice driving．Class time is not unlike any other class．The students have a
text from which they study the basic（5）A they must know to pass the written driving test that is given to anyone wanting to get a driver's （6）C．
Driving time is a chance for the students to get behind the steering wheel and practice start，steering，backing up，parking，switching lanes，turning corners，and all the other operations
（7）C to drive a car．Each student is required to drive a total of six（8）B．The students are divided up into groups of four．The students and the instructor go out driving for two-hour blocks of time．Thus，each student gets half an hour driving time per outing．The instructor and"driver"sit in（9）C  seats and the other three students sit in the back．
Drivers'ED cars are unlike other cars in which they have two sets of brakes，one on driver side and one on the other side where the （10）B sits．Thus，if the student driver should run into（11）A，the instructor can take over．The car also has another （12）D feature．On the top of the car is a sign that（13）A：STUDENT DRIVER．That lets nearby drivers know that they should be especially（14）A  because the student driver is a beginning driver，not very experienced and intended to drive（15）D．

Beyond two or three days，the world's best weather forecasts are based on guesswork，and beyond six or seven they are worthless．
The Butterfly Effect is the reason．For small pieces of weather-and to a global forecaster，small can mean thunderstorms and snowstorms-any （41）K fails rapidly．Errors and uncertainties （42）J，gathering upward through a chain of unstable features，from dust devils （尘旋风） and windstorms up to continent-size eddies （旋风） （43）I satellites can see．
The modern weather models work with a network of points of the order of sixty miles apart，and even so，some （44）Gdata has to be guessed，since ground stations and satellites cannot see everywhere．But suppose the earth could be covered with sensors spaced one foot apart，rising at one-foot （45）H all the way to the top of the atmosphere．Suppose every sensor gives perfectly （46）A readings of temperature，pressure，dampness，and any other quantity a meteorologist （气象工作者） would want．Exactly at noon a（n） （47）F powerful computer takes all the data and （48）D what will happen at each point at 12.01，then 12.02，then 12.03 …
The computer will still be unable to predict whether Princeton，New Jersey，will have sun or rain on a day one month away．At noon the spaces between the sensors will （49）E alterations that the computer will not know about，tiny variations from the （50）C．By 12.01，those alterations will already have created small errors one foot away．Soon the errors will have multiplied to the ten-foot scale，and so on up to the size of the globe．

7．Sometimes the people who are noticed the least can do the most to lift us up．On Thanksgiving（41）AI took part in a local running activity．It was barely above freezing that morning so every runner was walking or jumping around trying to stay （42）D．
On the side of the road was a（n） （43）C man and as usual，most people pretended not to  （44）B him．I went over and talked with him for a few minutes（45）A the race．He told me that he was a veteran （老兵） and had hoped he might be able to do some work to（46）Ba few dollars for a Thanksgiving dinner．
It was time for the race so I told him I'd like to talk to him（47）DI thought about this man during most of the （48）C．He hadn't asked me for anything，（49）D I wanted to do something for him．However，I only had a couple of dollars，certainly not （50）Bfor a Thanksgiving dinner for the man．
After the race I went back and talked to him，which got me several （51）Blooks from other runners．During our conversation I offered him the （52）C I had．He didn't want to accept it but I  （53）A．Then he said something that I didn't（54）BHe said，"This has been so nice．Thank you．I haven't really （55）A anybody in a real long time．"
"Wow，"I thought．"This man is（56）Cme for just talking to him．"After I said goodbye，I asked other（57）Dif they had a couple of dollars for a homeless veteran who just （58）A to buy a hot Thanksgiving dinner．I think he ended up getting enough for a good （59）Bthat night．From him，I learned how to smile through the rough times and I was（60）C not to take for granted the many blessings I have．

Latest figures from Cancer Research UK show smoking is the biggest avoidable risk factor，followed by unhealthy diets．It advises people to live healthily，limit alcohol intake and do regular exercise．
According to the figures from 2007to 2011，more than 300，000cases of cancer recorded were linked to smoking．A further 145，000were linked to unhealthy diets containing too much processed food．Obesity contributed to 88，000cases and alcohol to 62，200．Sun damage to the skin and physical inactivity were also contributing factors．
Professor Max Parkin，a Cancer Research UK researcher，says："There's now little doubt that certain lifestyle choices can have a big influence on cancer risk，with research around the world all pointing to the same key risk factors．
"Of course everyone wants to enjoy some extra treats during the Christmas holidays so we don't want to ban beef pies and wine but it's a good time to think about taking up some healthy habits for 2015．
"Leading a healthy lifestyle can't guarantee someone won't get cancer but we can stack the odds in our favour by taking positive steps．"
Public Health England says a healthy lifestyle can play an important role in reducing cancer risk．It says campaigns such as Smokefree，Dry January and Change4Life Sugar Swaps all aim to raise public awareness．It's important that we continue to make progress in noticing cancer earlier and improving treatments，but helping people understand how they can reduce their risk of developing cancer in the first place remains important in dealing with cancer．
