    In Atlanta，the USA，there is a popular restaurant which is very special．In the restaurant，waiters no longer throw uneaten food into litter cans．Instead，② ．

    In America，a new activity known as"zero waste"is becoming popular．It is carried out in schools，cafes，gyms，parks，restaurants and other places．"Zero waste"activity calls on people to produce less litter．It encourages people to reuse whatever they can．

    Although the idea seems a little unrealistic （不现实的），it is necessary．According to a new report，American people produce the largest amount of the litter in the world．Each person produces almost 4.6pounds of litter every day．More than half of the litter which is put into landfills is harmful ． Actually，this is bad for the environment．Besides this，more landfills（填埋场） are needed．

    "Nobody wants to have a landfill lying near his house，"said Jon D．Johnson from the Environmental Protection Agency，which helps to carry out"zero waste"activity．"There are not enough landfills，so we can't put all our litter into them．We should try to recycle it as much as we can．"

Recently, a short heart-warming video has been hot on the Internet. Many people have been interested in this video. Here {#blank#}1{#/blank#} the story.

two firefighters

On a hot September afternoon, a fire started in a neighborhood in a city. A woman and her little son were sleeping when the fire broke out. So they became trapped (困在) in their apartment on the {#blank#}2{#/blank#} floor. People called 119 and a team of firefighters soon arrived. Two firefighters {#blank#}3{#/blank#} into the room and helped the mother and the son get out through the window. {#blank#}4{#/blank#}, the mother and the son were saved and the fire was put out.

After they finished their work, this team of brave firefighters went to a nearby {#blank#}5{#/blank#} for dinner. But when the firefighters wanted to pay for their meals, they were surprised to find out that four young people had quietly paid for them.

In fact, such warm-hearted people can be found in many places in {#blank#}6{#/blank#}. Giving and receiving always work both ways. Offering help is a(n) {#blank#}7{#/blank#} part of Chinese culture. "When they were fighting against the fire, they didn't think of themselves," said one of the young people. In life, this kind of people, like policemen, {#blank#}8{#/blank#} and nurses, firefighters and others, who protect people from danger are {#blank#}9{#/blank#} as "unsung heroes". They deserve the acts of {#blank#}10{#/blank#}, thanks and respect for their contribution (贡献) to society.

①Tom lived with his grandfather, who is regarded as the wisest man in the village. Many people went to grandfather for advice or help. 

②One day, Tom saw three men walking together. They found a single-log（独木）bridge halfway, below which there was a deep river. 

③The first man didn't hesitate（犹豫）to step on the bridge and he made it to the other side of the river. The second man came close to the bridge. When seeing the deep river, he was so afraid that he made no move. Encouraged by the first man, he put his feet on the bridge. Although his right foot was hurt in the middle of the bridge, he got there safely. But the third man was the least brave to cross the river. It was getting dark. Behind him were some hungry wolves, he felt hopeless. But he had to be brave to cross the river. Only after a few steps, he fell into the river. 

④Seeing the puzzled look on Tom's face, grandfather said sincerely（由衷地，语重心长地）, "When in difficulties, the more time it takes to hesitate, the higher price you'll have to pay."

On May 24, 2021, 46-year-old Wang Hong reached the top of Qomolangma, which made him the first blind person from Asia to climb the world's highest mountain. Erik Weihenmayer and Andy Holzer made it in 2001 and 2017. They are the only three blind mountaineers to have climbed Qomolangma. Born in Chongqing, Wang became blind at the age of 26 due to glaucoma (青光眼). 

Both his father and uncle lost their sight because of the same disease, so Wang knew exactly what life would be like for blind people from an early age. He lived his life without goals. Luckily, he was saved by his wife. "I felt so hopeless then. But my wife was always there and encouraged me. Without her by my side, I couldn't have pulled myself together, " Wang recalled. Later, Wang became a blind masseur (按摩师). 

In 2015, by accident, he heard of the blind American mountaineer Weihenmayer, who climbed Qomolangma.     ★        . He then started to climb the mountains together with his guide. With the help of his guide, he did a lot of training, including rock climbing and walking on snow and ice. 

Wang also met many other mountaineers from all over the world. They all encouraged him even though they spoke different languages. Wang could feel their warmth through hugs or pats on his shoulder. Wang said the climbing of Qomolangma taught him many things, including how to trust people. 

"I can't see the world, but I want the world to see me." Wang said, "I've got so much energy from my family and these climbers. Now I'd like to share that energy with others and encourage other disabled people. "
