A
In 2018, I wanted to do something to bring change for people in my community.I carried out research to understand the problems affecting them and found that climate change was the greatest threat.When I realized many people in the rural areas faced fatal impacts such as landslides, floods and droughts, I decided to stand up.Seeing climate change threaten the availability of food and water in my country was a wake-up call.
We are focused and very clear with our demands.We are not afraid of holding governments and corporations accountable for the climate crisis because the science is clear.We will not give up because our future is at stake.We need to demand for climate action as our lives depend on it too, because we do.Farmers in Ontario stood up against a proposed mega quarry (采石场) in their land.They held festivals to draw attention, they spoke up against corporate mining which threatened their groundwater and soil, they mobilised many people to stop it and in 2012, Highland Company withdrew their plans.
I hope to see the end of the fossil fuel industry, and we need renewable energy.We need sustainability in every sector through green building and clean transportation.I hope to see recovery of our ecosystems through planting more trees, having urban forests and protecting wildlife.Our existence depends on that of our ecosystems.I hope to see more recovery projects built in the most affected communities.
There are many climate movements all over the world and most have social media accounts.Find a local group that you can work with to demand climate action.When people are united, they cannot be defeated.Earth is our home to protect.Everyone is needed.

The Antarctic's snow-white environment is going green and facing other unexpected threats.
Scientists say that as temperatures go up in the polar areas, invading (侵袭) plants and insects, including the flies, cause a major threat.
More and more of these invaders, in the form of larvae (幼虫) or seeds，are surviving in coastal areas around the South Pole, where the temperature has risen by almost 3℃ over the past five decades.Glaciers have melted, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before — providing potential green homes for invaders.
“The common houseflies are a perfect example of the problem the Antarctic now faces from invading species，” said Dominic Hodgson of the British Antarctic Survey.“They arrive by ship, where they exist in kitchens.They now have an increasing chance of surviving in the Antarctic as it warms up, and that is a worry.Insects like the houseflies carry bacteria that could have a deadly effect on native life forms.”
The Antarctic has several native species of insects.Together with its native mosses, these are now under increased threat from three major sources: visiting scientists, increasing number of tourists and global warming.However, it is global warming that is the main driver of the “greening” of the Antarctic.
In the 2015－2016 travel season, more than 38,000 tourists visited the Antarctic.“These tourists are often very careful about not leaving waste.But they could carry seeds or larvae on their boots when they set foot on the Antarctic，” said Dominic.
More and more invading insects and plants have been found on the Antarctic and have required removal.“The insects and plants that are native to the Antarctic have survived there for thousands of years，” said Dominic.“We have to act now if we want to save the environment.”

Keeping curious kids from disrupting wildlife
Interacting with the wild, naturally curious kids tend to collect seashells at the beach or keep small wildlife as pets.__9__ So how to help kids protect the wild while enjoying spending time outside Here are alternatives for some of the most common outdoor behaviour no-nos.
Take an interest, not things.Kids show interest in picking flowers, rocks, or shells outdoors.They're part of wildlife's habitat and play an important role.__10__ Let kids explore with a magnifying glass (放大镜) instead of their curious fingers.Let whatever they find outside stay outside.
__11__ It seems a fun idea to throw pieces of bread to ducks.Animals have unique dietary needs that are different from humans'.Eating human food can make them sick or become dependent on human food.Bears are an example of animals that often have to be killed after developing a taste for human food.
Admire animal afar, not disrupt nearby.The urge to take a photo with a squirrel, bird, or slow-moving turtle can be strong for kids.__12__ Instead, remind kids to stay away and show them how to use a camera's zoom button, or just admire with their eyes.
Take well-worn paths, not off-road romps (嬉戏)．Kicking piles of leaves, stepping on bushes, and walking through forested areas can unintentionally scare wildlife.If surprised animals defend their homes, everyone could get hurt.Nobody likes having a guest come in and destroy their home and act rudely.__13__
A．Keep snacks away from animals.
B．Share food if animals are hungry.
C．Exposure to them develops kids' love and curiosity.
D．The same rule applies to visiting wildlife in their homes.
E．Animals rely on plants for hiding; rocks and shells, for homes.
F．Approaching animals disrupts what they do for survival, such as eating.
G．Despite innocent purposes, kids' curiosity accidentally damages the wild.
语篇解读：本文是一篇说明文。文章介绍了怎样帮助孩子们在享受户外时光的同时保护自然环境。
9．选G 空前一句“与野生动物互动，生性好奇的孩子倾向于在海滩收集贝壳或养小型野生动物作为宠物。”说明孩子们喜欢与野生动物互动，选项G承接上文。选项中curiosity 和上文中的curious 一致。
10．选E 根据空前两句“孩子们对在户外采摘花朵、捡岩石或贝壳表现出兴趣。它们是野生动物栖息地的一部分，起着重要的作用。”可知，选项E承接上文，具体说明这些东西的作用。
11．选A 下文提到动物有着与人类不同的独特的饮食需求。吃人类的食物会使他们生病或变得依赖人类的食物。这说明向动物投送零食是不正确的行为，选项A概括本段主题，文意通顺，符合逻辑。
12．选F 本段首句“远远地观看动物，不要靠近打扰。”说明本段主题是不要靠近动物，选项F符合本段主题。
13．选D 空前一句“没有人喜欢有客人闯进来，破坏他们的家园，行为粗鲁。”选项D说明同样的规则也适用于野生动物。上下文语义通顺，逻辑合理。

参考词汇：垃圾分类 waste classification
Dear fellow students,
Yours,
Li Hua
参考范文：
Dear fellow students,
As you may have noticed, the program of waste classification in our school has kicked off.I am writing to call on you, members of the school, to take immediate action.
Every day, we produce plenty of waste, ranging from plastic bottles to paper, which not only leads to environmental pollution, but is also a waste of resources.Therefore, it is urgent for us to take an active part in the waste classification program.First, we can collect what can be recycled to save resources.Second, harmful materials should be sorted and treated properly to avoid pollution.Most importantly, we need to develop the habit of classifying waste.
Let's do it!
Yours,
Li Hua
