Emily, an eight-year-old girl, is not very {#blank#}1{#/blank#} because she has so many rules to obey every day.  

     At school, she can't arrive {#blank#}2{#/blank#}. She has to get up early in the morning. She {#blank#}3{#/blank#} run or laugh in the hallways and she can't eat or listen to music in class. She agrees {#blank#}4{#/blank#} these rules because they're reasonable. But there are some rules she can't {#blank#}5{#/blank#}. For example, she has to {#blank#}6{#/blank#} her school uniform from Monday to Friday. She can't wear a cap or a hat in the classroom. She can't talk {#blank#}7{#/blank#} in the classroom. She has to {#blank#}8{#/blank#} the blackboard and the classroom once a week.

     She also has to keep some rules at home. For example, she can't hang out {#blank#}9{#/blank#} watch TV after school. She has to finish her homework first. She can't meet friends on school nights. And she has to be in {#blank#}10{#/blank#} by nine o'clock. {#blank#}11{#/blank#} Weekends, she has to clean her room and {#blank#}12{#/blank#} her clothes. And she has to {#blank#}13{#/blank#} her mum do housework. Later she has to go to the Children's Palace to {#blank#}14{#/blank#}dancing. She never has any {#blank#}15{#/blank#}. What an unhappy girl!

    Hunting was once popular in the USA. Long ago the wild was filled with rabbits, bears and many other animals. Hunting provided people with a lot of meat. Also some expressions Americans use today{#blank#}1{#/blank#}hunting.

    One of the expressions is "to bark(吠叫) up the wrong tree". It comes from hunting raccoons(浣熊). The raccoon is a very clever animal. It{#blank#}2{#/blank#}during the day and comes out at night. Hunters used dogs to chase(追赶) the animals. The raccoon used many tricks to escape the dogs. Often it would travel through the river for a while to hide its{#blank#}3{#/blank#}from the dogs. It would also climb into a tree to rest, leaving the dogs barking below it. The hunter found the tree by walking to the sound of the dogs. He used a light to try to see the raccoon and then caught it. Sometimes, however, the raccoon was not in the tree. It had jumped to{#blank#}4{#/blank#}tree and escaped, leaving the dogs "barking up the wrong tree". The expression now means "to be mistaken" or "to look for something in the wrong place".

    Today, an increasing number of people are always looking at their mobile phones with their heads down. These people are {#blank#}1{#/blank#} the "Head-down Tribe". Head-down tribe members now can be seen everywhere.

    There are more and more traffic {#blank#}2{#/blank#} because there are more drivers using mobile phones while driving. In {#blank#}3{#/blank#} to make drivers pay more attention to driving, the government makes some new traffic rules. As we know, using mobile phone while driving or walking may cause traffic accidents. {#blank#}4{#/blank#}, more and more interesting and strange things also happen to {#blank#}5{#/blank#} "Heads-down Tribe". A man in America kept using his mobile phone on {#blank#}6{#/blank#} way home. As a result, he knocked into a big bear. When he saw the big bear, he was so afraid that he couldn't help crying out. And then he turned around and ran away as {#blank#}7{#/blank#} as possible. Besides, people often look at their mobile phone {#blank#}8{#/blank#} they are eating face to face in the restaurant. It's strange that they don't talk to the people {#blank#}9{#/blank#} sit opposite to them during the meal. Some of them even have fun communicating with others on the phone.

    Mobile phones are helpful and necessary {#blank#}10{#/blank#} in modern life. Whether they are good or not depends on how people use them. Let's be "healthy" users and try not to be the "Heads-down Tribe".
