People from all over the world visit Disneyland to have fun, not to get sick. But last week， an outbreak of measles（麻疹）spread from the Southern California theme park. As of Monday, January 19, at least 52 people have got the easily spread illness.

    The majority of the reported cases of measles are from people who visited the park before. According to the California Department of Public Health, these people were exposed to the illness at Disneyland from December 17-20.

    Officials believe the cause is likely someone who caught measles abroad and visited Disneyland, but this has yet to be proved. However, in 2014, California had its highest measles infection rate in nearly twenty years. There were 66 cases of measles reported in the state―23 of them in Orange County, where Disneyland is located.

    Measles spreads very easily. It can be caught from coughing and sneezing. Crowded areas like theme parks are especially suitable for its spread.

    The illness starts with a fever and develops into symptoms including a cough， runny nose, red eyes and so on. About three out of ten people infected with measles will develop another health problem, including an ear infection or pneumonia(肺炎).

    The best way to guard against measles is to get vaccinated(打疫苗). An unvaccinated person is 35 times more likely to catch measles than someone who received a vaccination.

    {#blank#}1{#/blank#} People use money to buy food, furniture, books, bicycles and hundreds of other things they need or want. When they work ，they usually get paid in money.

    Most of the money today is made of metal or paper. {#blank#}2{#/blank#} One of the first kinds of money was shells.

    Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Elephant tusks, monkey tails and salt were used as money in parts of Africa.

    The first metal coins were made in China. They were round and had a square hole in the centre. {#blank#}3{#/blank#}

    Different countries have used different metals and designs for their money. {#blank#}4{#/blank#} Sweden and Russia used copper to make their money. Later some countries began to make coins of gold and silver.

    But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. {#blank#}5{#/blank#}The first paper money looked more like a note from one person to another than the paper money used today.

    Money has had an interesting history from the days of shell money until today.

B. But people used to use all kinds of things as money.

C. No one knows for certain when people began to use money.

D. People strung(串连) them together and carried them from place to place.

E. Money, as we know，is all made of paper.

F. They began to use paper money.

    Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone.

    The GazeSpeak app combines a smartphone's camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences. For people suffering from ALS（渐冻症）, also known as motor neurone disease, eye movement can be the only way they are able to communicate.

    "Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups," said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.

    "To mitigate the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable and easy to learn."

    The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.

    The sticker shows four grids of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids the letters they want belong to. The artificial intelligence algorithm is then able to predict the word or sentence they are trying to say.

    Zhang's research, Smartphone-Based Gaze Gesture Communication for People with Motor Disabilities, is set to be presented at the Conference on Human Factors in Computing Systems in May.

    We lived in a quiet neighborhood. One evening I heard a loud crash. Earlier my wife had asked me to the store for soft drinks. My teenage daughter Holly practiced her driving, so I sent her to the store in my truck.

    At dinner my son talked about how much he liked my truck. I enjoyed having it, but I said: "My heart is not set on that truck. I like it but it is just metal and won't last forever. Never set your heart on anything that won't last. "

    After hearing the loud noise, the whole family ran outside. My son shouted: "Holly crashed your truck."

    The accident took place in my own driveway. Holly had crashed my truck into our other vehicle(交通工具), the family van. In her inexperience, she had confused the brake(刹车) and the gas pedal(油门). Holly was unhurt physically, but she was crying, "Dad, I'm sorry. I know how much you love this truck." I held her in my arms as she cried.

    I still remembered how sad Holly was the night she crashed our truck, and how I comforted her. When Holly thinks back on her life, I want her to know that I love her a thousand times more than any piece of property(财产).

    I repaired the van, but the dent(凹痕) in my truck is still there today. Every day it reminds me of what really matters in my life.
