Ar Horqin Grassland Nomadic System in the Inner Mongolia autonomous region, listed on the list of Globally Important Agricultural Heritage Systems by the United Nations, 【小题1】 (demonstrate) the wisdom of herdsmen to work in harmony with nature.

The 【小题2】 (season) movement of herds among different pastures (牧场) plays an important role in maintaining the self-renewal and recovery 【小题3】 (capable) of the grasslands. While keeping soil fertility from degrading, the nomadic lifestyle can protect vegetation and make good use of water resources, 【小题4】 the growing population of people and livestock, still puts much pressure 【小题5】 the grassland resources. Locals have, therefore, come up with ways to avoid overgrazing. With ancestral wisdom 【小题6】 (root) in a time of relatively small societies, it may be unable to solve issues today. This is 【小题7】 modern planning can help with.

For example, since 2015, under the guidance of the local government of Ar Horqin Banner, the number of sheep and goats in the nomadic system 【小题8】 (reduce) from 390,000 to 190,000, while the number of cattle has been increased from 40,000 to 81,000 head. No more than 100,000 sheep are allowed to migrate to the summer camps every year. With 【小题9】 (scientific) designed grazing patterns ensuring sustainable development of the grasslands, herdsmen can maintain 【小题10】 more balanced relationship with nature.

World Tourism Day 【小题1】 (celebrate) every year on September 27th. It’s a day that reminds us of the 【小题2】 (important) of tourism and how it can bring people from different parts of the world together.

When we travel, we can see different sights and experience different cultures. We can learn about new foods, languages and customs. We can also see 【小题3】 (amaze) landmarks (地标) and natural wonders, such as mountains, oceans and forests. Some people like to travel to big cities, 【小题4】 others prefer to visit small towns or countryside areas. Tourism is not only about having fun, but it can also benefit (使受益) the people and the environment of the places we visit. When people are on a visit somewhere, they spend money 【小题5】 food, hotels, and gifts, which can help create 【小题6】 (job) and support local business. Tourism can also be helpful in taking care of the environment and wildlife by 【小题7】 (support) conservation (保护) efforts. However, we must remind 【小题8】 (we) that tourism can influence the environment and local cultures. We need to be respectful of the places we visit.

Anyway, World Tourism Day is a day when we celebrate the benefits of tourism and learn how 【小题9】 (make) sure that tourism doesn’t harm the environment or the people 【小题10】 live in the places we visit.

To stop plastic waste reaching the ocean, an Italian firm has invented 【小题1】 seems to be a perfect tool to pick up litter before it gets there. Almost 80 percent of ocean waste comes from 100 of the world’s 【小题2】 (large) waterways. So, stopping waste at source is a solution that can be 【小题3】 (whole) workable.

The company had to get over a few 【小题4】 (difficult) before it could test out the invention properly. For example, its device had to allow boats to easily pass through while being able to run 24/7 with no influence 【小题5】 the river’s environment. The result is River Cleaning. 【小题6】 (attach) to the river bed, River Cleaning is a series of buoys (浮标) that spin on axles (轴) powered by the natural flow of the river, with the ability 【小题7】 (collect) different kinds of waste. River Cleaning, 【小题8】 about 100 percent scalable (可缩放的), low-cost and low-impact solution, can collect 85 percent of the waste 【小题9】 (pass) by it. So, if it is used in all the right places, up to 85 percent of rubbish 【小题10】 (prevent) from entering the ocean in the near future.
