Freddie Forbes stared in awe (敬畏) at the platform in the packed school hall. The headmaster marched onto the stage, followed by the captains of the school soccer team and rugby side. Freddie watched enviously (羡慕地) as each was presented with an honors jacket for their contribution to the school’s sporting success over the previous year. When the next presentation of honors jacket would come around, Freddie knew there was little hope that he would be the receiver of one of these treasured items of clothing.
“I wish you all a happy summer holiday,” the headmaster announced. “Although most of you will be going away to sunnier parts, there are others who will be staying near their home. The local council has asked the school to undertake a project over the next six weeks to help clear up litter around the area and separate it for recycling. If anyone is interested, come to my office and you will be supplied with a litter picker, bags and heavy-duty gloves.”
Freddie knew he would be at a loose end over the holiday, so he went to the office along with four other boys to pick up the equipment needed to gather up the rubbish which littered the streets around the school. When he arrived home, his mother looked at him curiously as he placed the equipment on the kitchen table.
“What is this all about?” she asked with a smile on her face. “Mum, I’m an average pupil and I’m not very good at sports,” he replied. “This waste recycling is one way I can contribute to the good name of the school.”
“Just as long as you don’t get fed up and stop half way through,” said Mum.
“I have made up my mind to stick this out through thick and thin,” Freddie said confidently.

If the great dinosaurs hadn’t gone extinct, would they have dominated Earth today? There has been a debate about this possibility for decades. Recently two analyses have put the surprising cognitive (认知) abilities of dinosaurs — and their potential limitations — in a new light.
In one study, Suzana Herculano-Houzel at Vanderbilt University calculated the likely number of neurons (神经细胞) in dinosaurs’ pallium, a brain structure that is responsible for advanced cognitive functions. Research suggests that it is the number of neurons in these areas, rather than the brain size, that indicates an animal’s cognitive potential. For example, despite having a very small head, birds have more densely packed brain cells than many mammals (哺乳动物) and so can possess roughly as many neurons as monkeys. The result is that some birds show great cognitive abilities, comparable to the smartest non-human mammals. And it is precisely birds, being the only surviving lineage (宗系) of dinosaurs, that are Herculano-Houzel’s foundation. By comparing the relationship between brain size, number of neurons and body size in numerous existing birds and available fossils of dinosaurs, Herculano-Houzel concludes that a large dinosaur such as T. rex could have housed two billion to three billion neurons in its pallium. If so, dinosaurs could have had the capacity for tool use and planning for the future.
But neurons’ number may not be enough. For intelligence, brain architecture also matters. And this could be the weakness of dinosaurs, argues Anton Reiner from the University of Tennessee. Over 350 million years of separate evolution, mammals and dinosaurs found two rather different ways to organize cognitive functions. The mammalian neurons are organized in a relatively thin layer formed by compact columns. In each column, different parts can communicate with one another over short distances. In contrast, in the dinosaurs that survive today, namely birds, the organization is less compact. According to Reiner, expanding brain capabilities beyond a certain point could make the structure far more complex and less efficient than it is in humans. If this were the case, an increase in brain size would correspond to a greater distance between different parts of the brain, slowing down their communication.
The issue remains open to debate. Herculano-Houzel and Reiner each published a paper with rejections to the other’s argument. Meanwhile, other scientists have entered the fight. For example, neurobiologist Giorgio Vallortigara assumes that speed in transmitting information between networks of neurons is probably one of dinosaurs’ strengths.
Whatever the truth is, understanding how and if brain architecture imposes limits on the development of cognition could reveal much about the evolution of abilities and behaviors of various animals. Also, this debate may tell us more about our own species than about dinosaurs.

6 . Mass public participation in afforestation efforts takes root. Zheng Jinran and Yuan Hui report from Chifeng, Inner Mongolia autonomous region.
In the Tengger Desert last month, yellow sand danced on the breeze and a profusion of sweetvetch(甜豆)swung its green leaves.
"In summer, you can see an amazing flower ocean when the plants bloom with their small pink, yellow or purplish petals," said Liang Cunxin, from Alshaa Left Banner, Inner Mongolia autonomous region.
"The enduring vitality of such plants on the barren land is astonishing," said the 53-year-old, whose family lived in the area for decades but was forced to relocate in 2007 as a result of desert encroachment.
"The government encouraged us to plant saxaul and little-leaf pea shrubs, which are commonly used to fix dunes in deserts, but the survival rate was unsatisfactory so we switched to this plant, and it has worked," he said.
The Tengger covers about 43,000 square kilometers in Inner Mongolia and Gansu province, making it China's fourth-largest arid area.
More than 2 million sweetvetch shrubs have been planted since 2017, and the hardy perennial has gradually covered more than 33 sq km of desert, Liang added.
Like Liang's family and their peers, about 400 million people from 30 provinces and regions have been affected by desertification, which by 2019 had covered a combined area of 1.68 million sq km, or 17.58 percent of China's total land area, according to data from the National Forestry and Grassland Administration.

When John pulled into his mother’s driveway with his young daughter, Lily, the sight of the familiar lychee (荔枝) tree welcomed them. “Look, Lily,” John said, pointing to the towering tree in the front yard. “It’s the family tree.”
Lily smiled as John treated the tree as if it were a real family member, patting its trunk (树干) affectionately. As they were admiring the tree, the screen door opened and out stepped Grandma Mei, bathed in the warm Florida sunlight. Grandma Mei, who came from the province of Guangdong in China, was known for her green thumb, particularly when it came to lychees.
Seeing her granddaughter, Grandma Mei adjusted her baseball cap and asked if Lily was ready for some lychees. But Lily hesitated, for the fruit’s appearance was unlike any other fruit she had tried before. With a laugh, Grandma Mei gave her a gentle hug. “More lychees for me then, John,” Grandma Mei said.
“Let’s get busy!” John said with enthusiasm, rubbing his hands together. “Family tree’s waiting.”
Hearing Dad calling the tree by name, Lily couldn’t help laughing. “Laugh if you want, Lily, but this tree is really family. On cold nights, before family tree was fully grown, Grandma Mei used to take my blanket and throw it over that tree.” Grandma Mei nodded, adding that she had to protect the tree from bad weather so that it would become a big strong tree and grow fruit for the whole family.
John, eager to start the day’s work, began climbing the tree, determined to harvest the best lychees for the family. Lily watched in amazement, noticing the clusters (簇) of lychees, their skin rough yet inviting.
As John skillfully cut through the branches with a cutter, Lily expressed her concern for the well-being of the tree. John explained to her that cutting the ends of branches won’t hurt family tree. Instead such behaviour made it healthier and stronger.

10 . This is the time of year when many gardeners are harvesting tomatoes. Gardening expert Jessica Damiano recently reported about the many pictures of strangely shaped tomatoes sent to her from fans of her gardening advice.
Not every tomato on an affected plant will be deformed (改变形状), however. What are the possibilities? Under the right conditions (temperatures that are too hot or even too cold), this could affect one or two tomatoes per plant, depending on where they are in the development process and what the (weather) conditions are, said Timothy McDermott, a professor at Ohio State University. The possibility of one of your tomatoes developing a locule oddity (怪异) is about one in a thousand, McDermott said.
And, when harvesting your crop, remember:
A.select the good-looking ones. |
B.Any tomato can grow an extra locule. |
C.the funny-looking tomatoes taste just as good! |
D.What causes the unusual appearance of tomatoes? |
E.Unless otherwise diseased, they are perfectly good for eating. |
F.She said people sometimes question if the tomatoes are okay to eat. |
G.Provide shade for your plants when temperatures are predicted to remain above 32℃. |
