Nairobi is the capital of Kenya, Africa. It is one of the fastest growing ________ in the world. Sixteen percent of the city is Nairobi National Park. There are many ________ like lions and elephants in the park. Every year, a large number of people all over the world come to Nairobi to see the animals. But as the city ________, people and animals must live very close to each other. This can bring problems.

Many animals often run out of the park. The lions killed or ate farmers’ cows. But the farmer can’t ________ their cows. They need them to make money. So when a lion killed or ate a cow, it would be killed by the farmers. It wasn’t what the people wanted to do, ________ they didn’t know how to solve the problem.

How to make the people and the lions live close to each other ________? An 11-year-old boy, Richard Turere, came up with a good idea. He said to the farmers, “If you use flashing lights(闪光灯) on your farms, you can ________ your cows. When lions see the flashing lights on the farms, they will think ________ is there. And they will not get close to the farm.” Many people believed his idea was reasonable (有道理的) and they ________ the boy’s advice. As a matter of fact, it worked ________. Thanks to Richard, in Nairobi lions will not kill cows and people don’t need to kill lions. They now live close to each other peacefully.

Spring Morn

Awakened to the dawn (黎明) of spring

And everywhere I hear birds sing.

Last night was filled with wind and rain,

How many blooms aground they bring?

If you live in Beijing, you may notice that the air these days is not as clean as it was during the summer. Fall and winter are the seasons with the worst air quality in northern China. It’s partly because people burn coal to heat their homes. Moreover, compared to the same period last year, higher temperatures, few windy days and little rainfall since September have made pollution worse, Xinhua reported.

To stop pollution from getting worse, Chinese government has made an action plan. It aims to control air pollution in the Beijing-Tianjin-Hebei region and nearby areas during the autumn and winter seasons, according to China Daily.

The plan sets higher goals. The average density (平均浓度) of PM 2.5 in the Beijing-Tianjin-Hebei region and nearby areas should drop by 4 percent from Oct 1, 2022 to March 31, 2023, according to the plan. Last year’s goal was 3 percent.

Also, the number of days with serious pollution should fall by 6 percent, the plan says.

This year’s plan has some highlights (亮点). It calls for “more scientific” production restriction (限制) in different industries.

The plan sorts factories or companies in 15 fields, including steelmaking and glass production, into three grades. Grade A companies are those that have very few emissions (排放). They will not have to restrict production. Grade B companies will face some restrictions. The plan will set the strictest restriction for Grade C companies.

This approach makes this year’s plan stand out from previous (以往的) ones, Chai Fahe, deputy director of the national Joint Research Center told China Daily.
