1 . Usain Bolt burned about 10kcal of energy to win his gold during the 200 metre spring final at the Olympic Games, which could roughly power an old 60W light bulb for 11 minutes. If you could make use of all the power generated by all the athletes during the Games, you would still be nowhere close to reaching the 29.5 billion Watts consumed overall by the athletes, spectators and organizers over the event. We take sport for granted, but do we ever consider its cost to the planet?
From the water required to maintain the golf course during The Masters tournament to the hundreds of flights it takes to bring football fans to a World Cup, major sports events are not helping much in the fight against global heating. What’s more, there is a lack of recognition within sport of its responsibilities and little discussion about possible solutions.
This is strange, given that the effect works both ways: the climate crisis is not just affected by sports, but it is already having a negative impact on many sports. When ice-climber Will Gadd set out to conquer the world’s glaciers, he didn’t realize it would become a race against climate change. “I thought glaciers are there forever.” When he arrived at the summit, Gadd was shocked: “The ice…wasn’t there. The things I planned to climb were gone.”
Global heating is noticeable in other sports. Amy Steel played professional netball until she suffered from heatstroke after playing in 39℃ conditions and unfortunately, the damage was permanent. Not only that, but extreme weather events made more frequent as a result of global heating mean sporting events are more often delayed or canceled. This has cost sport billions in potential earnings.
Yet sport can be a powerful motivator: it can unite whole nations behind its teams. Could sport have a role to play in driving climate awareness? Will Gadd and Amy Steel are among many athletes who think so? One thing is certain. Sport must put climate change at the top of its agenda and decarbonize at a Usain Bolt-like pace to make a difference.

2 . A lot of manufactured glass today made from sand and sodium carbonate(碳酸钠) can be reused or melted down and recycled into new items, but it doesn’t break down in the environment and will sit in landfills for thousands of years. A team of Chinese scientists aimed to deal with this environmental concern by developing an eco-conscious alternative.
In a study published recently in the journal Science Advances, a team at the Chinese Academy of Sciences’ Institute of Process Engineering describe how they engineered biodegradable glass made from amino acids(氨基酸). That glass would have a smaller impact on the environment and can break down in a few weeks or in several months.
In a test, glass beads(玻璃珠) made out of amino acids were placed under the skin of mice, and the breakdown of the bead and the skin healing process were observed for 30days. A diagram from the study shows how the mice’s bodies broke down the beads. In that month, the glass implant degraded beneath the skin, the wound site healed, and fur grew back. “Throughout the experimental period, no mice exhibited any pain-related behavior that may have been caused by the glass implantation, and none of them experienced obvious weight loss,” the researchers wrote in their paper.
Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can break down quickly in heat. In order to overcome this hurdle, the researchers chemically modified the amino acids using the heating-cooling procedure applied in glass manufacturing. This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher.
“It’s important to point out that this biodegradable glass is currently in the lab stage, and far from large-scale commercialization,” emphasized Yan Xuehai, a professor involved in the study, in a press release.

Indeed, the effects of weather on mood depend on our behavior and on how we think.
| A．Similarly, grey weather may encourage serious and calm thinking |
| B．Aspects of weather beyond heat and sunshine have also been shown to affect mood |
| C．Weather provides a vivid language for describing our emotional atmosphere |
| D．Temperature can also affect our mind and behavior |
| E．But the effects of weather on mood are not entirely biological |
| F．Anything that changes our moods can affect our behavior |
| G．Basically, weather will only influence us if we are outdoors experiencing it |
Celebrating tradition: The enchanting Mute Festival of Qixuan village
Qixuan village, a remote Yi village located deep in the
This age-old tradition
During the festival, visitors can not help but notice the careful preparations
One of the most striking moments is
What my father wore embarrassed me! I wanted him to dress like a doctor or lawyer, but he always dressed like my father, getting up before dawn every day to make breakfast for my mother and me.
We lived in South Texas, where my father worked as a repairman. He often wore a pair of jeans and a shirt, keeping his pencils, glasses and wrenches (扳手) in his breast pocket. His boots were those with steel toes that made them difficult to pull off his feet, which I sometimes helped him with when he returned from repairing cars — his job that also shamed me.
I blamed the way he dressed. I felt that my classmates laughed at me because they’d seen him mowing lawns (修剪草坪) in cut-off jeans and black boots. My classmates’ families paid men to beautify their lawns, while their fathers travelled in the bay wearing lemon-yellow sweaters and expensive shoes.
He preferred clothes that allowed him the freedom to move under cars. So even when taking part in a school trip with me, he was dressed in his repairman’s suit. On the school bus to the campsite, all students on the bus happily chatted with their parents except me, who lowered the head, avoiding spotting my classmates’ mocking glance (讥笑的眼光) or hearing their jokes, which I thought was about nothing else but what my father wore.
I regretted telling my parents the school trip, and I was very angry why my mother had no spare time while my father happened to have a vacation. But my father failed to read my mind. He was very happy, whistling a tune along the way.
Though my father didn’t sense my bad mood, the school bus seemed as sad as I was. It drove more and more slowly and finally it stopped on the roadside. The driver got out to check the bus but found nothing wrong. Students and parents on the bus began to whisper about what was happening, worried that the delay might spoil the journey.

7 . You can travel alone, with friends, or with a tour group. They all have strong points and weak points.
The best thing about traveling alone is that you can do what you want to do. No waiting around in places you aren’t interested in, no missing a bus because your friend was late. This may sound selfish (自私的), but this is your experience. Your experience will be greatly improved by traveling alone.The main worry is loneliness, but believe me, it’s not difficult to talk to and meet people. Just remember everyone is in the same boat; everyone wants to meet new people, have fun and be friendly! There’s a problem of safety in some countries, especially for women traveling alone. You should always check the foreign office of your country for advice on safety. Buying a personal alarm (警报装置) is a good idea for women traveling alone.
Traveling with a friend does sound nice, but it depends on how well you get on. If you have similar interests or travel ideas, it should be wonderful. You will find it much cheaper to cook food in developed countries and share a room. However, a lot of people I meet traveling together don’t seem to be having as much fun and often go their separate (各自的) ways.
Tours are great when they go well. Some of my best memories (记忆) have been with tour groups. The key there is when they go well. A terrible tour guide, quiet group and terrible food can ruin our time. My advice would be never to do a tour that is too long except in countries with safety problems or poor transport.
All in all, traveling alone is the best, but it is good to mix it up. Invite a friend from home to meet you for a few weeks. Try a tour or two — some people love them — perhaps start with a day tour.
1. What should a woman do if she wants to travel alone?| A．Check the map often. | B．Get an alarm. |

8 . Larry seemed always silent and didn’t have any friends. His teacher Mr. Brown noticed (注意到) this. One day, he asked Larry to meet him after class. Mr. Brown said, “I see that you don’t talk to anyone or show any interest in anything. What’s wrong?” Larry answered, “Sir, I have a very difficult life. I have to face some very sad things and I always keep thinking about them. Because of this, I can’t focus on (集中注意力) anything and even don’t feel like talking to anybody.” Mr. Brown listened carefully, thought for a while and said, “Would you like some lemonade (柠檬汽水)?” Larry felt a little surprised and nervously said, “Yes, thank you!”
While preparing lemonade (柠檬). Mr. Brown added more salt (盐) but less sugar (糖). Larry made a strange face as soon as he drank a sip (一小口) of that lemonade. Seeing this, Mr. Brown asked, “You don’t like it?” “Um… it’s just because there is a bit too much salt in it,” Larry answered.
Mr. Brown stopped him, “Oh, it doesn’t matter. I will throw it away.”As the teacher was lifting the glass to take it away, Larry stopped him and said, “Sir, please don’t throw it away. If we put a little more sugar in the lemonade, it will be fine to drink.”
Hearing this, Mr. Brown said happily, “This is what I want to hear from you. To improve the taste of lemonade, we don’t need to remove (去除) the salt from it. Instead, we can just add some sugar to it. Similarly, we can not remove sad things that have already happened to us, but we can add sweetness of good experiences in our life. If you keep on crying about your past, neither your present will be right nor the future will be bright.”
Larry realized his problem and began to live a happy life.
