People often talk on their mobile phones when they are driving. But talking or sending messages over a mobile phone can be as{#blank#}1{#/blank#} as drunk driving. They can't pay more attention to the road safety any more. Because of this, about 330,000 people are hurt and more than 2,000 people {#blank#}2{#/blank#} every year.
Now, an American company invented a key by using Bluetooth technology {#blank#}3{#/blank#} help people drive safely. With the key, a driver can't talk or send messages when driving a car.
With Bluetooth technology, when the driver is driving, the phone will{#blank#}4{#/blank#} all incoming calls and messages by itself with “I am driving now. I will call you later.” The only calls allowed out are to emergency services. When the driver {#blank#}5{#/blank#} the car, he then can use the phone. This is all about saving lives and safer driving.

                                                                      The population in China
   China has the{#blank#}1{#/blank#} population in the world, and about one {#blank#}2{#/blank#} of the people in the world live in China. Because of the large{#blank#}3{#/blank#}  , there is less{#blank#}4{#/blank#} space for each family. And it's difficult for lots of people{#blank#}5{#/blank#}  jobs.

    It's necessary for parents to teach kids how to cook from an early age. I believe you will {#blank#}1{#/blank#} with what I say. However, you also need to {#blank#}2{#/blank#} that part of teaching your kids how to cook is teaching them about the ingredients(材料).

    One of the best ways you teach them about ingredients is to take them to go shopping with you. I know it won't always be {#blank#}3{#/blank#} to do so. Maybe you have to spend some money {#blank#}4{#/blank#} your crying kids the big model car, because you don't want {#blank#}5{#/blank#} people to look at you.

    For one thing, it's great to let your kids see what food looks like in its {#blank#}6{#/blank#} state(状态). I don't mean seeing cows and chickens {#blank#}7{#/blank#} around (though that is good, too). I mean that they can see fruit, meat and vegetables before you {#blank#}8{#/blank#} them up or make them become dishes.

    In fact, if you live near a farmer's market, you can take your kids shopping with you there. At the farmer's market, your kids can talk to the people who grow the food. At {#blank#}9{#/blank#}, it will make your kids see whole(整个的) pineapples(菠萝), but not {#blank#}10{#/blank#} yellow rings with the hole in the middle.

He could play {#blank#}5{#/blank#} the piano and the violin before he was six. He wrote hundreds of wonderful {#blank#}6{#/blank#} of music in his life.
