13-year-old boy Omkar Dubey (from India) shows that when you start by changing yourself and have courage, you can make a d【小题1】 to the world.

In India, more than 100 million homes have no toilets. Dubey’s family didn’t have a toilet, e【小题2】. So he asked his father to build one. “ I thought it would be difficult on rainy days to go to the toilet. If we built a toilet at home, it would be e【小题3】 for all of us in the family,” he told the Indian news channel CNN-IBN.

At first, his father said it was a waste of space, but Dubey kept on a【小题4】 for nearly a month. Finally, his father gave in and built a toilet. But Dubey’s work didn’t stop there. He bravely went to the leader of his village and asked him to build the f【小题5】 public toilet. Today, his advice has led to 13 public toilets.

Dubey also brought the change to his school. When one leader c【小题6】 to his school, he took the chance and asked f【小题7】 a toilet. Now the school has two clean toilets for boys and girls.

“Omkar is an excellent kid. He will shine one day,” Said his teacher.

Max Woosey is a 12-year-old boy. He has slept outside in storms, snow and heat waves, but now he’s coming indoors.

After two years of 【小题1】 (sleep) in a tent, Max, who has raised over £700,000, is about to remember what a bed 【小题2】 (feel) like. “I’m still going to be in my tent a lot,” said Max. “But now I’ve done two years. If there’s a big, 【小题3】 (danger) storm coming, I may come inside.”

Max began camping out in March 2020. At that time, 【小题4】 old neighbor of his, Rick Abbott, who was 【小题5】 (serious) ill, gave Max a tent and told him to take a risk with it. Later Max decided to camp out to raise money 【小题6】 the hospital that cared for Rick. Max didn’t think he would keep going a long time, 【小题7】 it went on and on.

Over the two years, Max has been through around 15 tents and has had camping 【小题8】 (trip) in many places. He even slept on a hotel balcony (阳台). His dad joined 【小题9】 in the tent during last month’s Storm Eunice, with Max joking that he 【小题10】 (wake) up not by the wind but by his dad’s snoring (鼾声)!

Suppose you find a bright yellow bike on a street corner in the city. You hold on it and ride away. But wait, isn’t this 【小题1】 [streɪndʒ]? No one shouts, “Stop! Thief!” That’s because this free ride is just fine with the city.

You can find hundreds of free yellow bikes in some American 【小题2】 (city). The idea began in Portland, Oregon, in 1994. People saw 【小题3】 need for free transportation, and they wanted to help 【小题4】 [kən'trəʊl] pollution. So, to get citizens out of their cars and onto pollution-free bikes, they 【小题5】 (start) the Yellow Bike Project.

The public bikes are painted bright yellow and placed throughout the city. People can hop on a yellow bike and ride to work or to 【小题6】 [skuːl]. They then leave the bike 【小题7】 the next rider.

There have been times when bikes have been stolen, 【小题8】 most people obey the rules. What would be the point of 【小题9】 (steal) something that’s already free? Portland’s idea became popular 【小题10】 (quick). Within two years, similar programs were set up in cities in six other states.
