1 . Since the African Union first launched Great Green Wall in 2007, the initiative has struggled to make headway. Made up of local efforts across 11 countries, it has reached just 16% of its overall goal. But last month, the project, which analysts estimate will cost at least $30 billion, got a major boost: a total of $14 billion in funding over the next 5 years from a union of international development banks and governments.
Environmental restoration and community development specialists welcomed the news. But many are also apprehensive. In recent years, research by ecologists and social scientists has shown that many forestry projects in Africa have failed because they didn’t adequately address fundamental social and ecological issues.
The project leaders often planted species in places where they didn’t belong, and did little to help the young trees survive. “Tree planting is often viewed as the simple act of digging a hole,” forest scientist Karen Holl said. “But this short-term view has resulted in large quantities of money being spent on efforts that have failed almost entirely.”
In Africa, the adoption of one approach called Farmer-Managed Natural Regeneration (FMNR), is credited with regreening a notable portion of the Sahel. The low-cost restoration technique took off in Niger in the 1980s and has since spread to other nations. It relies on farmers to protect and nurture trees that grow from existing root systems and seeds in the soil. Over decades, FMNR has led to greater tree cover and other ecological benefits, such as higher soil carbon content, researchers have found.
But many efforts, particularly those not led by local communities, stumble (蹒跚而行). Newly planted trees can die of neglect when planners don’t engage communities from the start in discussions about which species to plant, as well as whether residents are willing and able to provide the water, fertilizer, and protection from grazing animals that trees need. “The farmers are often busy and have their own priorities; they will not manage trees that they do not value,” forest specialist Abayneh Derero wrote in a study.

It was an extraordinary day in the heart of the Nepalese Himalayas, where nature’s grandeur unfolded in every direction. The sun shone high in the sky, casting a golden glow over the grand mountain range. The air was crisp and clean, filled with the smells of pine and earth, while the views were breathtaking, with snow-capped peaks towering above us and thick green forests spreading out below.
Our group, a band of adventurous souls bound by friendship and shared enthusiasm for exploration, walked excitedly along the winding trails, all eager to explore the unknown and embrace the challenge of the mountains. We were making our way through the forest, the sun shining through the leaves cast dancing patterns on the ground, when we heard a scary cry for help. Our hearts skipped a beat, and we quickly followed the sound, our footsteps becoming more urgent as we realized the seriousness of the situation. We soon found a young woman struggling on the edge of a steep cliff. She had slipped and was hanging insecurely by a branch, her face filled with terror and desperation.
Without hesitation, I rushed to her side, ignoring the danger that lay before me. Grabbing a rope from my backpack, which I had fortunately prepared before, I tied it securely around myself and handed the other end to my friends, whose hands locked tight, forming an unbreakable human anchor. I carefully edged my way down the cliff, feeling the sharpness of the rocks beneath my feet.

6 . Find the learning style that suits you best
To succeed academically, you need to be productive. To be productive, you need to find a suitable learning style. Whether it’s for everyday learning or revising for exams, the learning style that helps you achieve maximum productivity will be crucial.
Note-taking
Note-taking can include copying out passages of books or summarizing concepts on notecards.
Sometimes you might find that you learn things more easily if you have to explain a concept to someone else. This is because in order to explain something clearly to someone else, you have to have a thorough grasp of it yourself. For example, giving a presentation to fellow students will require you first to have an excellent understanding of the topic and then to put together materials from which the others can learn.
Learning by doing
This method means that rather than reading things in books, try to experience things in real life.
Tests and mock exams (模拟考试)
A.Explaining to others |
B.Diagrams and mind maps |
C.If so, visual methods of learning might suit you best. |
D.Here are some common learning styles and choose one that suits you best! |
E.Some people like them because they provide strong motivation to succeed. |
F.It’s a classic learning method, but may not be the best way for everyone to learn. |
G.For example, you could conduct a scientific experiment or observe how a chemical reaction works. |

9 . Not all great writers are great spellers. If you want to be published, it's vital to submit a perfect, professionally presented manuscript (原稿).
I keep two reference books close-by on my desk: dictionary and thesaurus (同义词词典). I don't trust my laptop's spellchecker.
In addition, I have an old two-volume copy of the Shorter Oxford Dictionary, picked up a few years ago in a bookshop sale for just 99 pence. Of course, with its 2,672 pages, it's not exactly short. It contains around 163,000 words, plus word combinations and idiomatic phrases.
For well over a hundred years the most influential English dictionary was Samuel Johnson's Dictionary of the English Language published in 1755. "To make dictionaries is dull (乏味) work," wrote Johnson, illustrating one definition of "dull".
A.I don't often use this dictionary. |
B.It takes no account of the context. |
C.But I still don't want to replace them. |
D.But a dictionary can be a pleasure to read. |
E.Of course, a dictionary is not only for spelling. |
F.That means good grammar and no spelling mistakes. |
G.Dictionaries don't always give you enough information. |
10 . In the race to document the species on Earth before they go extinct, researchers and citizen scientists have collected billions of records. Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for detecting shifts in the number and variety of species in an area, a new Stanford study has found that this type of record is not perfect.
“With the rise of technology it is easy for people to make observations of different species with the aid of a mobile application,” said Barnabas Daru, who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences. “These observations now outnumber the primary data that comes from physical specimens (标本), and since we are increasingly using observational data to investigate how species are responding to global change, I wanted to know: Are they usable?”
Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns.
“We were particularly interested in exploring the aspects of sampling that tend to bias (使有偏差) data, like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it,” said Daru.
Their study revealed that the large number of observation-only records did not lead to better global coverage. Moreover, these data are biased and favor certain regions, time periods, and species. This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby. These data are also biased toward certain species with attractive or eye-catching features.
What can we do with the imperfect datasets of biodiversity?
“Quite a lot,” Daru explained. “Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places — and even species — that are not well-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image.”
