閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。
    A trained Search and Rescue （SAR） dog can help us locate victims of natural disasters，accidents and crime.So，do you want to train your dog for search and rescue work？A dog that is friendly and approachable makes for a fantastic search dog.While it is true that training a puppy（小狗）is definitely easier，it doesn't mean that training a grown dog is a lost cause.Puppies need to interact with several humans of all ages as much as possible，so that they become more approachable.
    Take your dog out on regular walks in the park，make him run and sweat regularly.SAR dogs are required to be good at swimming，hiking and walking in various areas that aren't safe.Ideally，this dog needs to be exposed to all the elements of nature so that the conditions during an actual task don't take him by surprise.
    An average dog can hear sounds between frequencies ranging from 40 Hz（赫茲）to 60 kHz，which is really sharp.A SAR dog，on several occasions，needs to take helicopter，snowmobile or speed boat rides，which can be really noisy for their sensitive ears.Dogs that are used to harsh sounds perform well under any circumstances，and those sharp ears always come in handy to locate sounds that even humans can't hear.
    Following a scent（氣味）is a quality that comes naturally to all dogs.To train your dog to follow the scent，you'll need a piece of cloth and three or four small buckets（桶）.The buckets should be placed close to each other in the upside down position.Then，take the piece of cloth and let the dog smell it.This piece of cloth should be taken away from the dog and placed under one of the buckets.
    Allow the dog to smell your clothing and secretly hide in another room.Let another person command the dog to find you.When the dog has found you successfully，a reward in the form of a treat should follow.As your training advances，you must repeat this exercise using different people，and on different outdoor locations，under varied weather conditions and at different time of the day.

1．閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。
     Natalie Doan，14，has always felt lucky to live in Rockaway，New York.Living just a few blocks from the beach，Natalie can see the ocean and hear the wave from her house. "It's the ocean that makes Rockaway so special，" she says.
      On October 29，2012，that ocean turned fierce.That night，Hurricane Sandy attacked the East Coast，and Rockaway was hit especially hard.Fortunately，Natalie's family escaped to Brooklyn shortly before the city's bridge closed.
      When they returned to Rockaway the next day，they found their neighborhood in ruins.Many of Natalie's friends had lost their homes and were living far away.All around her，people were suffering，especially the elderly.Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.
     In the following few days，the men and women helping Rockaway recover inspired Natalie.Volunteers came with carloads of donated clothing and toys.Neighbors devoted their spare time to helping others rebuild.Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless highrise buildings.
     "My mom tells me that I can't control what happens to me，" Natalie says，"but I can always choose how I deal with it."
      Natalie's choice was to help.
     She created a website page matching survivors in need with donors who wanted to help.Natalie posted introduction about a boy named Patrick，who lost his baseball card collecting when his house burned down.Within days，Patrick's collection was replaced.
     In the coming months，her website page helped lots of kids：Christopher，who received a new basketball；Charlie，who got a new keyboard.Natalie also worked with other organizations to bring much-need supplies to Rockaway.Her efforts made her a famous person.Last April，she was invited to the White House and honored as a Hurricane Sandy Champion of Change.
    Today，the scars（瘡痍）of destruction are still seen in Rockaway，but hope is in the air.The streets are clear，and many homes have been rebuilt. "I can't imagine living anywhere but Rockaway，" Natalie declares."My neighborhood will be back，even stronger than before."

2．閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。
    When you are learning English，listening，speaking and writing are important，but reading can also be very helpful.When you read，you can not only learn some new words，but also you can learn how to use these English words.When you read，it gives you a good example for writing.
    Read something that you can（more or less） understand.If you need to stop every three words to use a dictionary，it is not interesting.Reading books with a reasonable number of new words is very important.If there are four or five new words on a page，write them in your notebook.But you don't have to write them while you read.Instead，try to guess their meaning as you read，and mark them with a pen.Then come back when you have finished reading to look them up in a dictionary and write them in your own vocabulary book.Then try to remember them.
    You should develop a good habit of reading.For example，read for a short time once a day.Fifteen minutes every day is better than two hours every Sunday.Fix（固定）a time to read and keep to it.You could read for fifteen minutes when you go to bed，or when you get up or at lunchtime.
    There are a variety of books in the bookstore，so what kinds of books should you choose？Choose a book or a magazine about a subject that you like，because you are going to spend time and money reading it.So，choose an interesting book.You can also read newspapers.There are many English newspapers in China，for example，21st Century Teens.It is easy enough for you to understand it.There is something interesting in it.

3．閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容摘要。
    With the development of the computer，virtual reality（虛擬現(xiàn)實）steps in our life.If something is virtual，then it is created by computer technology and appears as if it were real.VR is a computer system with a special headset（耳機(jī)）.When you put on the headset，you will look at two tiny television screens.They are so close to your eyes as if you see just one picture and you will believe that you have entered a different world.In many systems，you also wear special gloves.With the gloves you can reach out and touch things in the unreal world.
    The first VR games，which have already been sold round the world，enable you to drive a sports car，fly a plane，or fight an enemy.In the future，it may be difficult to tell the virtual world of the games from the real world outside.However，VR is not just for entertainment.One day，delighted children will be able to learn geography by observing exciting foreign countries without having to leave their classrooms.They will be excited to learn history by visiting the pyramids of Egypt.In addition，businesses will be able to use VR for many tasks.Pilots will be able to practise flying virtual planes before they go into the air.VR can help us improve the world in hundreds of ways.
    However，some people have warned that there could be dangers.It might be dangerous if we do something wrong，or if people do not want to return to reality because it is safer than real life.Besides，we will forget how to live and work with real people.
    There will be some problems with VR，as it is new for us.However，one thing is for sure：VR is here to stay.Get ready to step into another world!
