In some parts of Holland the land lies so low that the people have to build great walls of sand and earth, to keep out the sea. These walls are called dykes(堤坝).

Sometimes the water from the sea break down these walls, and then the sea rushes in through the beach, and spreads over the land.

Houses and trees, cows and sheep, have been thus washed away, and many people drowned(溺水).

Once, when a little boy was going home in the evening, he saw a hole in one of the dykes, through which the water was flowing(流出）.

His father had often told him that when this happened, unless the water was stopped it would soon make the bole so big that the sea would flow over the land.

At first he thought he would run home and tell his father. But then he said to himself," It may be dark before father can come, and we shall not be able to find the hole again. Or it may get so large that it will be too late to stop it. I must stay now, and do the best I can alone.

The brave little boy sat down, and put his hand in the hole, to keep back the water. There he stayed, hour after hour, in the cold and the dark, all through the night!

“There is a hole in the dyke,” said the boy,“ and I am keeping back the water.”

Poor little boy! He was so cold and tired that he could hardly speak.

The man came quickly and set him free. He got the hole closed up, and thus the land was saved--thanks to the brave little Hollander!

Food and Drink Banned on Subway

Travelling by subway can sometimes be quite an adventure, especially during rush hour. There are the times when you have to     49     cups of coffee that could spill on（洒在……上）you. The smells of some passengers’ food are very     50    , too.

According to the Beijing subway passenger regulations（规则）, which went into effect on May 15, 2019,     51     except babies and the sick are no longer allowed to eat or drink on the subway. Violators（违反者）who     52     after being asked to will be asked to get off. The violation will also be recorded in the violators’ credit records.

Some support the rule, citing the reason that the     53     of food and drink can annoy（惹恼）other passengers.

“The smell of food fills the carriage, causing people discomfort,     54     in the hot summer. Besides, eating on the subway unavoidably produces     55    . And on subway trains, people often spill their drinks,” Zheng Yiou, a student from Hefei No. 8 Senior High School, Anhui Province, told TEENS.

However, others question this rule. “Some citizens live so far from their work places that they have limited time     56     breakfast before they go to work. Eating while they travel saves them time and decreases the chance that they will be late for work,” He Songlin, a student from Chengdu Shishi Tianfu High School, told TEENS. “And some people, like those with low-blood sugar levels, will     57     if they can’t eat when they must.”

Other Chinese cities like Nanjing and Chengdu have     58     regulations. Some foreign cities also ban eating and drinking on the subway. For example, eating and drinking have long been banned on subway in Washington DC, reported China Daily. Singapore fines people who eat or drink on the subway up to 500 Singapore dollars (2, 417 yuan).

The Beijing 2022 Winter Olympics was a great success. China has kept the promise to hold a green Olympics. Many green actions made it possible, like providing environmentally friendly smart beds, using new energy cars, supporting sporting places with 100% clean energy and reusing rain and snow water.

Take making ice as an example. China didn’t use R507a common material to make ice because it isn’t friendly enough to the environment. Through 18 months’ hard work, China independently developed the CO₂ direct cooling technology.

A net of tubes runs under the ice. High-pressure liquid (液态) CO₂ goes through them to create heat exchange. The CO₂ evaporates (蒸发) under the ice surface. The evaporation takes in heat and turns water on the surface into ice. And the CO₂ goes into another circle. This technology helps to make ice better and faster. And above all, it is much greener because there’s no new CO₂ produced. Among all the 15 ice sporting places in the Winter Olympics, 7 used the CO₂ direct cooling technology to make ice. As a result, much less pollution was caused.

Beijing did so much more to save energy. Beijing built the new sporting places with green materials. As for the old ones, Beijing used new glass walls to take the place of traditional walls to let more natural light in. 70% of the waste heat was also reused to keep warm and dry. And a large number of new energy cars were used at the Beijing 2022 Winter Olympics.

The Beijing 2022 Winter Olympics is the first to truly achieve carbon neutrality (碳中和), and it has set new standards in green technologies. Some newspapers say China has set an example for the world in environmental protection and green development.
