You might take a car, a bus, or a bike to school. But in Bangladesh, instead of waiting for a school bus to come down their street, many students wait for a school boat to come down the river. That’s right—these students attend school on a boat!

Bangladesh is very close to sea level.    1     The flooding creates many problems. For the nearly 160 million people living there, the periodic flooding means that they are often unable to access roads, electricity, or telephones.

Growing up in Bangladesh, Mohammed Rezwan was often troubled by these disruptions. In 1998 he founded an organization called Shidhulai. The name means “self-reliance.” The purpose of the organization is to help the people of Bangladesh receive an education and also to bring technology and an improved quality of life to poor people in remote areas of the country. In 2002, Rezwan began transforming boats into schools. Each boat was built to house between 30 and 35 students. The boats had everything you might find a in regular classroom. The only difference was that they floated on a river.

    2     Today Rezwan and his organization operate 88 boats in northern Bangladesh. About half the boats are used as schools, and the other half are used as temporary houses during the flood season. In addition to the schools and the temporary housing, there are also a floating technology and training center, a library that allows students to check out books, and a health-care center. The school boats travel along the rivers and pick up students for classes that include computer technology, agriculture, and human rights.

At night the boats provide additional learning opportunities for students and adults.     3     They study using solar lamps that are charged during the day at stations near the river. Special equipment on the boats also projects lessons onto big screens made from sailcloth. People can come down to the riverbank to watch films. In all, these boats help educate close to 90,000 families in Bangladesh.

By floating down the rivers, the school boats provide more than books.     4     “This ‘library’ boat inspired me,” said 18-year-old student Shanto. Islam, who enjoys reading science fiction books. “I started to dream.” Islam now wants to attend a university.

If Apple were to become the only ________ company we would be left with few options for top-of-the-line phones.

During the outbreak of COVID-19, almost everyone in China wears a mask to     1     themselves against the virus.However, many people in the West feel     2     to wear masks, even if there is an increasing number of their compatriots being infected.

According to the Global Times, different attitudes toward wearing masks largely lie in the cultures. In the West, what people     3     believe that unless one is already ill, wearing а mask is simply     4    .

Siva Kumar from the US is one of them. “Masks can only protect you from particulate matter in the air you breathe, but they can' t hold up microbes," Kumar told China Daily. “Wearing a mask when you’re healthy will     5     tension for others.”

US infection prevention specialist Eli Perencevich told Forbes, The average healthy person shouldn' t be wearing masks." She added, “If they wear them     6     it can increase the risk of infection because they’re touching their faces more often.”

However, for people in Asian countries like China, wearing a mask is deep- rooted in their culture.Valuing collectivism(集体主义), people in Asia always want to make     7     to the groups that they belong to. In such uncertain and potentially dangerous time, many people have taken their responsibility to wear masks to ensure the safety of their     8    .

Chen Xinjie, a media worker in Beijing, said, Wearing the mask for a long time is hot, stuffy (闷热的) and uncomfortable...But as a member of the group, it’s our duty to do so.

Influenced by social cultures, the     9     toward wearing а mask can be different in the East and West. But as US essayist Ralph Emerson once said, “We must each     10     others even as we respect ourselves.”
