Few people would even think of beginning a new job at the age of 76, {#blank#}1{#/blank#} one of America's most famous artists did just that.Anna Mary Robertson, better known as “Grandma Moses”， turned to painting {#blank#}2{#/blank#} she was too old to work on her farm.

Grandma Moses was crazy about painting soon after she picked it up and worked hard at it.She painted {#blank#}3{#/blank#} (care) and her works were nice.She first painted only to please {#blank#}4{#/blank#}， and then began to sell her works {#blank#}5{#/blank#} a little money.In 1993, a collector, Louis Caldor happened to see several of Grandma Moses' works {#blank#}6{#/blank#} (hang) in a shop.He liked them, {#blank#}7{#/blank#} (buy) them at once, and set out to look for {#blank#}8{#/blank#}．Caldor held {#blank#}9{#/blank#} show to introduce the works of Grandma Moses to other artists. Grandma Moses, {#blank#}10{#/blank#} was world­famous, died on December 13, 1961, at the age of 101.

    While {#blank#}1{#/blank#}(wait) for the airplane to take off,I was happy to get a seat by myself. Just then, {#blank#}2{#/blank#} air hostess approached me and asked,"Would you mind {#blank#}3{#/blank#}(change) your seat?A couple would like to sit together."The only possible seat was next to a girl with her arms in casts（石膏绷带）,a black and blue face,and a sad {#blank#}4{#/blank#}(express)."No way am I going to sit there,"I thought {#blank#}5{#/blank#}(immediate).But a soft voice spoke,"She needs help."Finally,I decided to move to that seat.The girl was named Kathy.She was hurt in a car accident and now was {#blank#}6{#/blank#}her way to treatment. When the snacks and juice arrived,it did not take me long to realize {#blank#}7{#/blank#}Kathy would not be able to feed herself.I considered {#blank#}8{#/blank#}necessary to feed her but hesitated,as it seemed too impolite to offer a service to a stranger.But then I realized that Kathy's need was more important than my discomfort.I offered {#blank#}9{#/blank#}(help) her eat, and although she was uncomfortable to accept,she did as I expected.We became closer and closer in a short period of time.By the end of the five-hour trip,we had become friends.Love sometimes flows beyond human borders and {#blank#}10{#/blank#}(remove) the tear that keeps us separate.When we offer to serve another,we grow to live in a larger and more rewarding world.

    Earthquakes are quite common. In fact, thousands of earthquakes {#blank#}1{#/blank#} (happen) almost at every moment. {#blank#}2{#/blank#}, most of them are too weak to feel. During a big earthquake, there is often a big noise first. Then the earth shakes {#blank#}3{#/blank#} (terrible) and many houses fall down.

    As one of the most deadly natural disasters in the world, the earthquake often result {#blank#}4{#/blank#}many people being injured or killed. In 2008, a severe earthquake hit China's Sichuan Province, {#blank#}5{#/blank#} (kill) more than 80,000 people there.

    Besides the great damage and {#blank#}6{#/blank#} (death) caused by the earthquake, other accidents such {#blank#}7{#/blank#}fires often follow. More buildings may be damaged and more {#blank#}8{#/blank#} (injury) may be caused. For centuries, people have been making studies of earthquakes. About 2,000 years ago, for example, a Chinese scientist {#blank#}9{#/blank#} (name) Zhang Heng invented a machine which could find out the direction{#blank#}10{#/blank#} the earthquake waves came.

    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.
