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.

9 . A man named Randy liked to look for big trees and old trees. He made maps to show where these trees were. He did not want to cut them down. He wanted people to take care of them.
Randy was told that there was a very tall tree on Vancouver Island. The tree was said to be 314 feet tall. That would make it the tallest tree in Canada. Randy started to find the tree.
But someone else found it first. It was found by a logger (伐木工). Loggers wanted to cut down Canada’s tallest tree and all the trees around it.
Randy made a path in the forest so people could see the tallest tree. The tree was so big and beautiful that it would bring them enjoyment. More and more people wanted to save that forest. Thanks to these people, that forest is now a park. Canada’s tallest tree is still there.

10 . Blowing Up Balloons with CO₂
Chemical reactions (化学反应) make for some great experiments. You can make use of the CO₂(carbon dioxide) given off by a baking soda (小苏打) and lemon juice reaction to blow up your balloon!
What you’ll need:
●Balloon ●About 40ml of water ●Soft drink bottle
●Juice from a lemon ●I teaspoon of baking soda
Instructions:
●Before you begin, make sure that you pull the balloon long to make it as easy as possible to blow up.
●Put the 40ml of water into the soft drink bottle.
●Add the baking soda and mix it with water.
●Put the lemon juice in and quickly put the balloon over the mouth of the bottle.
What’s happening?
If all goes well, then your balloon should inflate! Adding the lemon juice to the baking soda creates a chemical reaction and produces CO₂. The gas rises up and escapes (逸出) through the soft drink bottle. It doesn’t, however, escape the balloon, pushing it outwards and blowing it up.
1. Which of the following do you need for the experiment?A.Two cups. | B.Apple juice. |
C.250 ml water. | D.A teaspoon of baking soda. |
A.Heat the water. | B.Drink some juice. |
C.Blow up the balloon. | D.Pull the balloon long. |
A.To describe an experiment. | B.To introduce a game. |
C.To produce soft drinks. | D.To save some chemicals. |
