二、完形填空
What does the word ecology mean It was 　11　 by Ernst Haeckel, a German biologist. He joined two Greek words: oikos, meaning "house", and logie, meaning "the study of".Together they mean "the study of the house". The "house" Haeckel had in mind is our 　12　,Earth. The Earth is home for all living things — humans, animals, plants and even tiny microbes.
To study a house is to learn how its residents(居民) use it. An ecologist is a scientist who studies the 　13　 between organisms (生物)and their environment. The environment is an organism's surroundings. It may 　14　 water, gases, rocks and temperature.
Ecologists also study the balance of using the environment while protecting it.
An ecologist once asked a boy 　15　 he thought it meant to protect the environment.
The boy said,"You go into the forest and look for somebody who wants to cut down a tree. You take away his axe. You tell him about how 　16　 trees are. You say they are good for natural beauty, saving soil and giving shelter to birds and other animals."
"It's a good answer," said the ecologist, "　17　 it may not be easy to find a woodcutter to talk to. Also, remember that sometimes it's necessary to cut down a tree. If we cut down too many trees, the forest will 　18　. If we don't cut down any trees, we won't get any resources from the forest. We have to find the right 　19　."
"I get it," the boy said. "We need the forest's 　20　 for wood and paper or we might not have desks or notebooks for school."
"Exactly — and school is a good place to learn about ecology," added the ecologist. "Then you will know how to protect the natural environment."

The Beijing 2022 Winter Olympics was a great success.China has kept the promise to hold a green Olympics. Many green actions made it possible,like providing environmentally friendly smart beds, using new energy cars, supporting sporting places with 100% clean energy and reusing rain and snow water.
Take making ice as an example.China didn't use R507,a common material, to make ice because it isn't friendly enough to the environment.Through 18 months' hard work, China independently developed the CO2 direct cooling technology.
A net of tubes runs under the ice.High-pressure liquid CO2 goes through them to create heat(热量) exchange. The CO2 evaporates(蒸发) under the ice surface. The evaporation takes in heat and turns water on the surface into ice.And the CO2 goes into another circle. This technology helps to make ice better and faster.And above all, it is much greener because there's no new CO2 produced. Among all the 15 ice sporting places in the Winter Olympics,7 used the CO2 direct cooling technology to make ice.As a result, much less pollution was caused.
Beijing did so much more to save energy.Beijing built the new sporting places with green materials. As for the old ones,Beijing used new glass walls to take the place of traditional walls to let more natural light in.70% of the waste heat was also reused to keep warm and dry.And a large number of new energy cars were used at the Beijing 2022 Winter Olympics.
The Beijing 2022 Winter Olympics is the first to truly achieve carbon neutrality(碳中和), and it has set new standards in green technologies. Some newspapers say China has set an example for the world in environmental protection and green development.
31.How long did it take China to develop the CO2 direct cooling technology
A. 18 months. B. 100 weeks.
C. 15 days. D. 7 years.
32.The writer writes Para. 3 to show 　　　　.
A. why the CO2 goes into another circle
B. how the new ice-making technology helped
C. how sporting places used the new technology
D. why the liquid CO2 runs through the net of tubes
33.According to the passage,we can infer(推断) that 　　　　.
A.all the buildings will be built with glass walls in the near future
B.the CO2 direct cooling technology may be widely used in the world
C. the high-pressure liquid CO2 will totally take the place of R507 soon
D.no new standards in green technologies may be set after the Beijing 2022 Winter Olympics
34.What does this passage mainly tell us
A. A new green ice-making technology.
B. Green technologies used in sports.
C. A shared future of green development.
D. The green Beijing 2022 Winter Olympics.
35.Teenagers may feel　　　　 when they read this passage.
A. proud B. afraid
C. nervous D. angry
四、任务型阅读
We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.
Reduce means "using less". Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good!
Reuse means "using again". Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not use paper cups or paper bags.
Recycle means "changing things into something else to be reused".We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber(橡胶). Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.

To Be a Good Traveler
Summer holiday is coming. Many people have already started planning their travel. Why not choose a green travel or voluntourism
Wherever we go, use environmentally friendly ways of transportation as much as possible, such as walking and riding a bicycle. Don't drop litter everywhere so that we can protect the environment. We can also do voluntary work, like helping others warm-heartedly during the trip. Before leaving, buying some local products is a good way to promote the development of local tourism.
Let's be a good traveler with awareness of environmental protection and social responsibility.
