People eat rice all over the world

    Rice {#blank#}1{#/blank#} (believe) to have been first grown in China or possibly somewhere else in eastern Asia around 10,000 years ago. {#blank#}2{#/blank#} earliest evidence of rice farming comes from a 7,000-year-old site near the lower Yangtze River village of Hemudu in Zhejiang province in China.

    Rice is a kind of food which requires much labor. In developed countries, the planting and harvesting is done {#blank#}3{#/blank#}(most) with machines. {#blank#}4{#/blank#}, in much of the world, these things are still largely done by hand. It takes one farmer 1,000 to 2,000 working hours {#blank#}5{#/blank#}(raise)a rice crop on 2.5 acres of land. The fact that rice needs so much labor means{#blank#}6{#/blank#}(keep)a lot of the population on the land.

    Rice is also a crop {#blank#}7{#/blank#} need of lots of water. The wet rice grown in most of Asia needs hot weather after a period of rain and conditions provided by the rainy seasons affect many of the places {#blank#}8{#/blank#} rice is grown.

    Rice straws(稻杆）{#blank#}9{#/blank#}(leave)in the fields add nutrients(营养物)to the soil after rice is harvested(收割). For the next crop, rice farmers can often enjoy a good harvest by adding little {#blank#}10{#/blank#} no fertilizer.(肥料)

    Did you grow up in one culture, your parents came from another, and you are now living in a {#blank#}1{#/blank#} (total) different country? If so, then you are a third-culture kid.

    The term “third—culture kid” {#blank#}2{#/blank#} (use) in the 1960s for the first time by Dr. Ruth. She first came across this phenomenon while {#blank#}3{#/blank#} (research) North American children living in India. In general, third-culture kids benefit from{#blank#}4{#/blank#} (they) intercultural experience and they often reach excellent academic results.

    Yet many {#blank#}5{#/blank#} (difficulty) may arise from this phenomenon. Third-culture kids may not be able to adapt themselves completely {#blank#}6{#/blank#} their new surroundings. Also, they often find it hard {#blank#}7{#/blank#} (develop) new friendship. Additionally, for a third-culture kid, it is often easier to move to a new country {#blank#}8{#/blank#} to return to his homeland. For example, after living in Australia for many years, Louis finally returned to the country {#blank#}9{#/blank#} she was born. She didn't know anything about current TV shows {#blank#}10{#/blank#} fashion trends. And she didn't share the same values as other teens of her age.

    Harry is an American businessman. His job requires him to do a lot of traveling. In the past six months he has made nine trips, {#blank#}1{#/blank#}purpose is to attend meetings and make presentations. Harry loves to travel and feels each country has a charm of its own. After graduation, Harry decided to make travel part of his career. He wanted to experience different cultures of other {#blank#}2{#/blank#}(country). He was dreaming of{#blank#}3{#/blank#}(work) for an international company. Then his dream came true. Now he's working for a German hi-tech company.

    In the 17th century, dentists did their best {#blank#}1{#/blank#} (make) false teeth. The problem, however, was not making the teeth, {#blank#}2{#/blank#} was keeping them in place. They had to tie each tooth to the one on either side of it. Only rich people could afford false teeth, {#blank#}3{#/blank#} were usually made of gold or silver. As more and more people wanted new teeth, poor people {#blank#}4{#/blank#} (sell) their teeth to the rich so that they could buy food and clothing. During the next 200 years, many changes were made to false teeth although some of these were not really improvements. Towards the end of the 19th century, for example, cheap elastic teeth were introduced. But they caught fire very {#blank#}5{#/blank#} (easy), and a number of men were badly burned when their teeth caught fire while they were smoking {#blank#}6{#/blank#} (cigarette). Nowadays, false teeth {#blank#}7{#/blank#} (be) so well made and look so real that it is often {#blank#}8{#/blank#} (possible) to tell from a person's appearance whether or not they have them. And in {#blank#}9{#/blank#} near future, very few people will have them by {#blank#}10{#/blank#} (add) certain things to the water we drink, we have been able to keep our teeth so healthy that most people will never need false teeth.

    {#blank#}6{#/blank#}(normal), an athlete in sports like track and field and ball sports retires in his or her 30s. Besides, injuries at a young age can affect our ability to keep {#blank#}7{#/blank#} (do) exercise in later life. In Chinese Kung Fu, however, it is {#blank#}8{#/blank#} different story. It {#blank#}9{#/blank#}(say) that Kung Fu not only exercises your physical body but also trains your spirit and your mind. And we can continue later in life when our {#blank#}10{#/blank#}(body) weaken.
