Glen James was a homeless man. One day last year, he found     1     bag in the door of a shop while he was walking around a shopping centre     2     the city of Boston.

At first, he didn’t know     3     to do, but when he opened the bag, he saw there     4    (be) a wallet with $40,000 in it. So then he took it to the police. Many people thought that Mr James did a     5    (wonder) thing. Later, a website     6    (decide) to raise money to help Mr. James because he had no home or job.     7    (Final), they raised over $140, 000 from people of different     8    (area) all over the world. Mr James said, “I’m     9    (surprise) and so happy. This is going to change     10    (I) life.”

4 . It was the final part of the 2016 World Triathlon (铁人三项) Series in Mexico. With just 700 metres to go, Alistair Brownlee was in third place and his younger brother Jonny, was in the lead. Alistair pushed himself towards the finish line in the burning heat, but as he came round the corner, he saw his brother about to fall onto the track. Alistair had to choose brotherly love, or a chance to win the race.

For Alistair, the choice was clear. His brother was in trouble. He had to help. Alistair ran towards Jonny, caught him and started pulling him towards the finish line. Alistair then pushed his brother over the line. The move put Jonny in second place and Alistair himself in third. It was an unexpected end to the race, but Alistair did not want to discuss it with the media. He just wanted to see his younger brother, who had been rushed to the medical area.

The Brownlee brothers have been doing triathlons since they were children. “Obviously, when your older brother is doing it, you think it’s a cool thing to do,” says Jonny. Alistair says that they encourage each other as much as they can when they train. Though there are arguments over “stupid things” now and then, Alistair agrees that having a brother is an advantage. “Throughout my entire life, I’ve had my brother trying to beat me at everything I do. It has been a fantastic driving force.”

Watched by millions, the ending to the race has different opinions: should the brothers have been disqualified (取消资格) or highly praised for their actions? But for Alistair, his decision was easy to explain:“Mun wouldn’t have been happy if I’d left Jonny behind.” At that moment, he was no longer an athlete aiming for a medal——he was just a brother.

After graduation from college, I started to sell. Soon I discovered that the     1    (worry) expression I had been wearing since childhood meant sure     2     (fail). I knew it wasn’t going to be easy to change that expression on my face left by the    3    (year) of hardship. It called for a complete change in my view on life.Here is the method I tried.

Each morning during a fifteen minute bath, I     4    (determine) to develop a big happy smile. I found     5    , however, that it couldn't be a forced smile developed just for the purpose of     6    (put) dollars in my pocket. It had to be an honest-to-goodness smile from down deep inside, an outward expression of happiness from within! Let's see    7    starting off with a good fifteen-minute workout of the smile muscles helped me during the day. Before entering     8    office I would think of the many things I had to be thankful for, work up a big smile and then enter.Seldom did it fail    9    (get) the same smile in return from the person I met. I also found that it     10     (great)pleased people when I passed them on the street to give them a cheerful smile.

Alice Thompson is a girl from Sydney, Australia. She had her first long     1     (distant) train ride at the age of 18. Together with a friend, she got     2     the famous Ghan train in Sydney and got off in Alice Springs. During the two days and nights, they ate meals     3     (cook) by experts and saw fields, desert and     4     (abandon) farms. In the daytime, Alice talked to other passengers and read some books. At night, she watched the stars in the sky     5     shone like diamonds.

Why is the train     6     (call) the Ghan? It is short for Afghanistan. A long time ago, Australians wanted to travel to the middle of their country, so they brought some     7     (train) camels from Afghanistan    8     (carry) food and other supplies, and returned with wool and other     9     (produce). They did that until     10     1920s, when the government built a new railway line and took the place of camels.
