根据短文理解完成下列各题。
   March 16 is World Sleep Day. This year's slogan is “Breathe Easily, Sleep Well”. Its aim is to celebrate the *benefits of good and healthy sleep.
   Fangfang, from Liaoning, just became a high school student last September. She gets up at 5:30 a.m. every day and goes to bed at about midnight. Fangfang feels sleepy all the time. “I want to finish all my homework first,” she said.
   Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep *Foundation in the US, adults need seven to nine hours of sleep every night. For students who are 10 to 17 years old, a healthy amount is about eight to nine hours every night.
   But many students don't get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don't get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can't fall asleep quickly. For others, they may even have insomnia, and usually they have to ask the doctors for help.
   These sleeping problems greatly *affect people's life. Some doctors found out that *lack of sleep for teenagers lead to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, they often become anxious easily.
   Luckily, with good sleep habits, it is easier to fall asleep. Some of these good habits include *avoiding drinks that make people excited late in the day, going to sleep at the same time every night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.
   More tips to get a good night's sleep:
   Exercising during the day. You'd better do sports three hours before going to bed.
   Don't eat big meals before bedtime. Drink a warm glass of milk. If you stay awake worrying about things, try making a list of things that you need to do before you go to bed.

Dorothy lived with her uncle Henry and aunt Em who were both farmers.Their house had only four walls,a floor and a small space under the floor to protect them from powerful winds.The house was in the middle of poor land with strong sunlight and few plants.Aunt Em used to be young and cheerful,but the sun and wind had taken away her happiness.Uncle Henry also looked serious and strict.Only Toto,could bring laughter into Dorothy's life.

One day,they heard low sounds of wind from both the north and the south.Uncle Henry realized a strong wind was coming.He rushed to protect the animals while Aunt Em hurried Dorothy to the basement.Suddenly,the house began to rock and rise to the air.In the center,but Dorothy found herself riding safely on the rising house.

Frightened,Toto ran around the room until Dorothy caught him and protected him from falling through the open door.She closed it carefully to avoid further danger.As hours passed,Dorothy slowly got over her fear.She finally fell asleep on her bed with Toto by her side.The wind had set Dorothy's house down gently in a beautiful country.

As she looked around, she saw green grass, fruitful trees, and colourful flowers.Birds with special feathers sang and flew around.As she stood enjoying the beautiful views, a group of strangely dressed people came near. They wore round hats that rose to a small point a foot above their heads. Three men were dressed in blue, and a little woman wore a white dress. They stopped and discussed in a low voice, as if afraid to come farther.

 Like many inventions, language translators(翻译器) were imagined by writers long before they became real. In Hugo Gernsback's 1911 novel A Romance of the Year 2660, characters use a video telephone that can translate from one language to another. A language translator also appears in Murray Leinster's1945 science fiction. In that story, humans and lives from another plane made a translation machine together after making first contact with one another.

 In 1954, the first real language translator was invented by engineers from the IBM company and Georgetown University, which could translate Russian sentences into English. However, the idea of the language translator didn't become truly popular until a special translator appeared in the TV show in the 1970. The translator was powerful, because it could translate any language that it met.

 Today, language translators are so pervasive that it's hard to imagine a time without it, especially for many young working or studying in other countries. Most of them can be reached easily online at no cost to users. With translation apps like Google Translate or iTranslate, users sometimes don't even have to look things up. All they need to do is pointing their phone's camera at some writing, and a translation appears at once. If users want to translate something being said aloud, they just turn on their phone's microphone. All of these save our time and effort.

 Translation apps make foreign travel much easier than before. They are important when it comes to communicating with taxi drivers or hotel managers who don't speak a traveler's native language. But these apps are far from perfect. Sometimes a translation makes mistakes, making the user guess what the translation means. At other times, the user might not know that the translation has failed until he or she shows it to a native speaker.
