What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)may be able to put the tooth back in for you, but you have to get to the dentist first．In the meantime, you have to store the tooth so that it will stay healthy．
The simplest thing to do is put the tooth back into your mouth, or you could put it in milk．Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth．He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液)．He also tried, just drying the teeth in the open air．He used teeth that had to be removed from people’s mouths for various reasons．The teeth were put into one of the solutions(溶液)or stored in the air for one hour．Then cells from the root of the teeth were scraped-off the teeth．Dr．Courts and the others then studied how healthy these cells were．
The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth．However, few people keep cell-culture medium handy at home or in school．
The next best thing was milk．But Dr．Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽)in the mouth．For some people, though, this is just too painful or upsetting．So milk will do, until you get your tooth (and your mouth)to a dentist．

I was walking down the road one day when my cell phone rang．  36  voice on the other end spoke to me, "Dad, please come back soon．I miss you so much! "I judged that it was a   37_  number．A little while later, the call came once again, so I rudely   38   , "You've dialed the wrong number! " and then   39

    During the following days, I got the same call   40   ．But I didn't care much about it．

    Then one day she constantly called me,   41   I didn't answer．Finally I answered the phone and heard a weak voice, "Dad, please come back．I miss you so much!  Dad, I'm   42   so much pain! Mom said you were too busy to take   43  of me．But, dad, please   44  me again, OK?" The innocent   45  was difficult to reject．I made a   46  kiss on the phone and heard the weak voice say, "Thank you．．．Dad, I am so．．．happy, so．．．happy．．．"

    Shortly after this, I became   47   about who had been on the other end of my phone．So I called back, and a woman answered, "Sorry, sir．I am really sorry to have   48   you．My daughter has suffered from bone cancer   49   she was born．And her father．．．died in an    50   a short while ago．I dare not tell her this   51   ．Poor baby．When she couldn't   52  the painful chemotherapy(化疗), she would cry for her dad, who had always   53  her．I really couldn't bear it, so I gave her a random phone number．．．"

    "How is your daughter now?" I couldn't wait to   54

    "She has   55   ．You must have kissed her on the phone, because she went with a smile, tightly holding the cell phone．．．"

When the musical sound rings you, you immediately reach for your pocket ready to have a chat．But although you probably use it all the time, have you ever stopped to think about the manners related to talking on the phone? If you haven’t, here are some tips to guide you．

●Always give the person you are calling plenty of time to get to the phone before you hang up．If the person who answers is not the one you want，give your name and ask if you may speak to the person you want．

●Think about the time you call people．Try not to call too early in the morning（before about 9:00）or too late at night（after about 9:30）．Also try not to call at mealtimes．

●If you go by plane to visit your relatives at Christmas, remember to follow airline instructions．Cell phones must be turned off as soon as the plane doors are closed and remain so until the doors open again on arrival．

●When face to face with someone, do not talk on the phone．It is rude to be on the phone when a waiter is trying to take your order in a restaurant, or when you are returning the shoes you have just been trying on in a shop．Finish any face-to-face business before taking a call．Continuing to use the phone while nodding to the person in front of you is quite impolite．

●When in a restaurant with your friends，keep phone conversations short．Make a call only if it is important．Practise speaking in a low voice．If no one looks your way, you’ve_got_it．

●If you go to a theatre, a concert or a cinema, consider the other people around you．Check that your phone is “off” before you enter．If you are expecting a very important call, put your phone on “vibrate”（振动）and run for the exit as soon as you feel it．If you forget both “off” and “vibrate” and your phone rings, don’t answer it, turn it off straight away．

Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.   1  However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace (支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.
Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position.
Undo your seatbelt.   2  Untie the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.
  3  Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.
Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car.   4    
Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival.   5  While there is still air in the car, take slow, deep breaths and focus on what you're doing.
A. Open the window as soon as you hit the water.
B. Surviving a sinking car is not as difficult as you think.
C. It takes 60 to 120 seconds for a car to fill up with water usually.
D. Such accidents are particularly dangerous to the risk of drowning.
E. In conclusion, if you know what to do in the water, you will be safe.
F. This is the first thing to attend to, yet it often gets forgotten in the panic.
G. But the sooner the window is open, the sooner you can escape directly through it.
