I am a 22-year-old artist. My journey through art led me to being an environmentalist.

    1    we consider waste may be useful when we think about it in a different light. Although largely    2     (ignore), materials thrown away provide plenty of resources for us artists to give them a second life. In my hands, glass bottles, plastic bags, and other waste    3    (item) become a form of sustainable art. I want to motivate the people who buy this type of art to contribute to the planet’s welfare.

2 . With climate change continuing to worsen, our situation is beginning to feel increasingly serious.     1     Is it right? Maybe not.

Techno-optimism is one of the greatest misconceptions when it comes to solutions to ensure our future. It can be defined as a belief that future technologies will solve all of our current problems. This definition reinforces (强化) the idea that there’s no reason to panic or change our current energy-intensive lifestyle. All society needs to do is look to green technology to work its magic.     2    

One of the best examples of this optimistic misconception is the electric car. Despite being highly regarded as an eco-friendly way to get around, electric cars are not the end for the future of transport. Batteries in electric cars use chemical elements which we could be seeing a shortage of by the midcentury.     3     Techno-optimism has led many to believe that if everyone just switched to driving electric vehicles, we would be making incredible steps towards sustainability. However, the reality is that the amount of resources and energy needed to produce enough electric vehicles for everyone is not even remotely sustainable.

    4     Investing in public transportation and moving away from individually owned vehicles. Producing fewer cars. Improving recycling practices of old batteries. The solutions we seek should not be rooted in new technology, but be about changing the way our society functions.

Techno-optimism puts too much emphasis on technology and not enough on what we can do right this minute. Unfortunately, people seem to like the picture that techno-optimism paints.     5     It is important to understand that the problem begins when we see those technologies as a way to make our current lifestyles eco-friendly. Until we are ready to face the need for a less complex life, we cannot make true progress towards sustainability.

The koala is a symbol of Australia. Recently, the Australian government has listed it as an     1    (endanger) species. This is because of a fall in its number. caused by bushfires and the cutting down of trees. There are about 50, 000 koalas in the wild now. The government     2    (give) koalas greater protection in the future, and a recovery plan     3    (announce) already.

COP26, known as “Conferences of the Parties”, was the latest in a series of     1     (meeting) bringing together governments to protect the environment. Its main goal was to take measures     2     climate change—long—term changes in world weather patterns that are linked to human activities including farming, industry and transport. Gases such as carbon dioxide,     3     are produced by these activities, trap heat in Earth’s atmosphere and cause temperatures to rise,     4     (lead) to extreme floods, heatwaves and storms.

Wind is one of our cleanest and most abundant power sources. Europe is leading the way in wind power. Nearly 75% of all turbines(风力发电机)     1    (locate) there. The country that produces the most energy from wind is Germany. However, Germany     2    (consume) a lot of energy, and wind only supplies about 5% of all its electrical needs. Denmark is the global leader in this field, which uses wind     3       (supply) almost 20% of its energy.
