In order to learn about advanced scientific technology and ideas for combating desertification, Rezaali Pakzad left the Iranian capital Teheran, in 2018, to study in Northwest China’s Gansu Province.
He is a 27-year-old doctoral student at Lanzhou University, focusing on soil desertification control. In his view, Iran, like other arid and semiarid countries, faces environmental problems such as desertification. When he did field surveys and research in Minqin county, Gansu, he found that the local desertification characteristics were very similar to those of his hometown.
“Minqin is between two deserts. From being “about to disappear” to being gradually green, from being ravaged by “sand devils” to being covered by vast green plants, the scientific and effective prevention and control methods of the Chinese government have greatly changed the county, and made me see the hope of improving the ecology in my hometown,” he says.
He believes that China has certainly contributed to the global effort to combat desertification, and that the Chinese contribution is worth learning from. China has developed advanced technology models, such as quicksand fixation and vegetation restoration, and protective forest systems along major transport routes, which have introduced more green to deserts.
Already among the top nations in the world in the field of combating desertification, China has shared its experience with other countries, carried out international exchanges and cooperation, and contributed to global desertification control, he says.
He believes he has made progress during his five years of living and studying in China. By learning more about the Chinese language and culture, he has adapted to life in China and enjoyed the help and sincere concern of his teachers, classmates and friends here.
He hopes to achieve a lot, at a high level, in his research field and to contribute to international exchanges and cooperation in desertification control. “I want to be an ‘ecological messenger’ by spreading green ideas,” he says.

【推荐1】Since the age of 5, Laura Lee has had what most would consider an odd habit-she collects toilet rolls. At that time, she didn’t know this habit would eventually become a nationwide recycling campaign.
In December 2018, as a 16-year-old student of Nanyang Girls’ High School in Singapore, Lee founded ToiletRollSG, a national project that aims to collect 1,000 kilograms of cardboard cylinders — or about 150,000 pieces. As of February of 2021, Lee, who was studying at Hwa Chong Institution, had collected 860 kg of toilet rolls, reported Singapore Today. Slightly later, she was awarded Singapore’s National Environment Agency’s Ecofriend Awards, which recognizes individuals for their contributions to the environment, under the Youth and Students category.
But why did she choose toilet rolls? “They are convenient to collect and also one of the purest forms of waste to recycle because they are made of only one material,” Lee told Singapore Today. “Project must be economically practical too. For example, it’s more difficult to recycle pens because they are made up of too many different materials like rubber casings, metals and plastics which require more resources to separate.”
Lee went into a partnership with the waste management firm Veolia, which gives her five cents for every 1 kg of toilet rolls collected.
She organized “toilet roll challenges” within Nanyang Girls’ High School and worked with cleaners to collect used toilet rolls from school toilets. She also conducted talks about ToiletRollSG. But due to COVID-19, she has been unable to conduct physical talks, so she raises awareness about different social causes through her Instagram Live series called On A Roll.
One of the biggest challenges Lee has faced has been others doubting her due to her young age. “I always have to use my actions as well as the different things I’ve done to prove that I’m passionate and know about this,” she told The Straits Times.
Lee will donate the money collected to a social cause that is focused on community health.

【推荐2】Earth Day is celebrated every year on April 22nd. Take some time to find out about how one man, who was determined to change the way we treated our planet, didn’t stop until he had made a difference.
In 1963, Senator Gaylord Nelson wasn’t happy with the earth’s condition. He wanted to clean up the planet, solve pollution and environmental problems. A senator is someone US citizens choose to help make laws, so Gaylord had a lot of power. He went to John F. Kennedy, the President at the time, with his concerns. The President agreed that the planet’s environment was a serious issue, so President Kennedy went around the country on a five-day tour to promote the idea of cleaning up the planet. People began making small changes but it wasn’t enough.
A few years later, Senator Nelson decided to put one day aside every year for the cause of saving the planet. On April 22, 1970, the first Earth Day was celebrated. Since then, Earth Day has become an international holiday. People all over the world are doing something to make Earth a cleaner, better place.
A rock band named Dramarama wrote a song about Earth Day in 1993 called What are We Gonna Do. People are paying more and more attention to save the earth.

【推荐3】We love the sea. We swim into it, live near it, build beside it, and even imagine living under the sea. But we’re terrified of it, too. For much of our history, we have turned to “hard engineering” to control the marine environment and manage its influence on us. We build dams, sea walls and channels. But all these efforts seem to fail. The sea has a habit of taking back its own. And we suffer.
Johnston, a marine ecologist, is advocating for “blue engineering” — the marine version of the “green engineering” movement on land that has seen nations like Singapore building the walls and roofs of the concrete jungle with plant life.
We are expanding further into the marine environment. This practice does harm to marine ecosystems. We’re loving the sea to death, but we’ve not been thinking about design of structures （建筑物） with respect to ecology. Some coastal structures create shade, which reduces the growth of seaweed. Bright lights at night contuse species such as turtles. That’s why blue engineering comes in.
Throughout the world people are starting to turn things around. Researchers with the World Harbour Project are creating tiles （瓦片） similar to the natural structures found on rocky shores with 3D printing technology. These make more attractive homes for marine creatures. Researchers are also actively seeding these tiles with local seaweeds and creatures such as the Sydney rock oyster, which is particularly good at improving water quality. Twelve harbors around the world are taking part in this marine tile experiment, each working with their own unique marine life.
It’s a far cry from the days when huge number of old tyres were thrown, into the sea to build “artificial reef”（人工礁石）. Those clumsy early attempts are now costing millions to remove, showing just how far we have yet to go in understanding how best to co-habit with the underwater world.
1. What do we know about “hard engineering”?| A．It can control the influence of sea. |
| B．It has improved sea environment. |
| C．It forces sea creatures to settle down. |
| D．It has not achieved its original purpose. |
| A．disadvantages | B．definition | C．necessity | D．measures |

【推荐1】Sitting on the “Roof of the World”, Mount Qomolangma National Nature Reserve is one of the world’s hotspots for biodiversity protection. Mount Qomolangma, also known as Mount Everest, is to be measured again by a Chinese team to make sure its exact height after last official measurement.
“Conducting research and protecting the region can help us learn more about the origin and development of the earth, as well as our human-beings and wildlife,” said Cheng Pengfei, president of the Chinese Academy of Surveying & Mapping (CASM).
The weather in the Mount Qomolangma area changes frequently. While the maximum temperature in the tent is more than 20 degrees Celsius, or even 30 degrees Celsius at noon, it may start snowing in the afternoon, and a gale may spring up at night, even blowing away the tents. Those taking part in the mission are ready for the task after preparing thoroughly at the base camp.
The complex geological environment has formed diverse landforms in the area. Distinctive snow mountains, valleys, rivers, lakes and glaciers can be found. And the unique ecological environment has also established a special biological diversity.

【推荐2】It’s common for children to grow up being told to minimize daydreaming, and instead to focus on lessons and class work. Historically, daydreaming students who go off on their own thoughts, rather than focusing on the teachers, the blackboard, or their class work, are often encouraged to stop allowing their attention to wander and to bring themselves back into the present moment. They’re described as uninterested in school work and their future. Traditionally, daydreaming is seen as a practice that results in bad consequences.
But recent studies are beginning to renounce those common beliefs by pointing out the potential benefits that daydreaming may provide. PsychCentral reports that Mary Smith, a psychological scientist and researcher, recently examined scientific writings and studies to gain a better understanding of the role of a reflective brain. These studies have shown that the brain has a network that is active when a person is daydreaming and that brain network can help memory and learning.
Though paying attention in school is important, these results suggest that there should be time for students to daydream, too. Giving them the chance to reflect and daydream can help improve learning and development. Research also indicates that when students are permitted to daydream, they experience less anxiety and become more motivated. On the other hand, if students are warned against daydreaming, their knowledge of themselves and the world around them may suffer.
As a result, educators are encouraged to promote a balance between outward and inward attention. A little bit of daydreaming to break up the hard focus on school activities can be beneficial, and it may help students become better, active learners.
As for students, the lesson here is not to be afraid of doing some daydreaming. Sure, you want to pay attention to the vital information conveyed to you during your classes, but don’t get discouraged if your mind wanders. A little bit of daydreaming is healthy.
1. What do people usually think of daydreaming students?| A．They live in the future instead of in the moment. |

Historically, the country was a colony claimed by people from Portugal and this made Portuguese the official language. The Portuguese reached Brazil in 1500 and until that moment it was inhabited by semi-nomadic(半游牧的) people. The Portuguese changed Brazil into a country of slaves until 1800, when Maria I of Portugal came to live in Brazil. The Queen did not stay long in Brazil, but during the 20 years of royal presence a lot of changes occurred: commercial ports to United Kingdom were opened; Brazil stopped being isolated(孤立) from other countries. So at the moment of getting the independence on the 7th of September, 1822, Brazil already had the potential to develop. The Brazilian Empire, Pedro I, abolished slavery in 1888 in the face of Princess Isabel. A lot of European people started coming to Brazil and the industry of the country started working. In the 19th and the 20th century as it has been said above foreign people immigrated(移民) to Brazil and basically 5 million European and Japanese people became the residents of Brazil. The beginning of the 20th century was especially marked by the immigration of a lot of Asian people: Japanese, Korean and Chinese immigrants. As a matter of fact Japanese people do not immigrate a lot, and the fact that the Brazilian-Japanese people are the largest Japanese minority in the world does astonish greatly.
The majority of the cultural inherits of Brazil are actually Portuguese, due to the fact that Brazil was Portugal’s colony for a very long time. The southern states mainly consist of European population and the north and the northeast consist of a mixed population including Africans, Amerindians and Europeans. Most of this population is Roman Catholic. No other country in the world has the same amount of Catholics. The modern tendency of Brazil is the growing number of people calling themselves Protestants. Around 7.4% of the population don’t believe any god. Some Brazilians, especially in the northern states are mixed Africans who prefer following the traditional African religions. Only 1.8% of the population chose Buddhism, Islam or Judaism.
Though Brazil always tried to maintain democracy, it was failed several times by the dictatorship（独裁） of Getulo Vargas. This fact could not affect the political situation in the country.
