This shows how Chinese people care about the    2     ( protect) of these giant friends.

The 15 wild Asian elephants among    3     one male turned back in July finally returned to their habitat after touring for 17 months in Yunnan Province. The case was taken by the experts as a    4     ( success) example on how to protect and guide the migration of wild elephants.

Zhou Jinfeng, Secretary of the China Biodiversity Conservation and Green Development Foundation, mentioned an idea which focused    5     helping wild animals survive by     6     (reduce) the harm to nature and wildlife in our daily lives.

Zhang Chenglin, Deputy Director of the Beijing Zoo，who introduced some measures taken by Chinese zoos to take good care of elephants,     7     (say) that there were around 150 elephants living in zo0s around China.

“    8     ( human) and animals share nature. To protect elephants     9     (be) to protect our planet. Hope we can work with other countries to protect wild animals."     10     woman wrote on Sina Weibo on the World Elephant Day.

The people     1     live in Wenchuan county will never forget the day 12 May, 2008. The 8.0-magnitude earthquake    2     killed over 80, 000 people and left many more injured turned many towns and counties into ruins. The rescue work    3     followed was carried out by people from all over the country, and even abroad.

Now, more than10 years on, the people    4     suffered the earthquake are living    5     new life. Many live in new towns    6     are earthquake-safe, in local communities    7     have been beautifully rebuilt by the government. The people will never forget those    8     rescued them and helped them rebuild their home. Out of gratitude, many young adults    9     were students during the earthquake have chosen to study medicine or join the army in a wish to help more people. Wenchuan, the county    10     was completely destroyed and then completely rebuilt, has become a symbol of the Chinese spirit of never giving up.

Every day we use energy. We use it for cooking, for heating and for lighting our cities. The energy comes from many different     1     (source). It can come from the sun, wind and water, but the energy we depend on the most comes from deep inside the Earth. These include coal, oil, and natural gas.

These fuels come from the remains of plants and animals. It takes millions of years     2     (make) them. However, with the world’s population     3    (grow), more and more of these fuels are dug up from the ground. Yet these fuels are non-renewable. When they     4    (use) up, they will be gone forever.

We need to have a strong sense of     5    (responsible) and it’s high time for us to think about     6     we can help save energy and preserve these fuels.

What about turning off anything     7     (electricity) we are not using? That’s a start! We can also recycle things such as newspapers, cans, bottles, and plastic—including plastic bags. Plastic bags start out as either oil     8     coal, and one big city can use millions of plastic bags in a year. When we use recycled things, it takes less energy     9     making something new.

Cars consume a lot of fuel, but there     10     (be) a variety of measures that car owners can take to preserve fuel. Try asking your family whether we can take a bus or walk instead of using the car.

Now a group of students at Glen Hills Middle School in Glendale, Wisconsin, are working to reduce their ecological footprint.     1     (lead) by science teachers Jennifer Clark and Chloe McClendon, the Green Team holds meetings every Tuesday and Thursday after school     2     (study) climate change and environmental pollution.

Glen Hills is     3     (national) recognized as a “Green Ribbon School”. To earn the recognition, a school must meet such     4     (requirement) as developing cost-effective energy, getting rid of     5     (harm) waste, and improving the health of students through various programs.

Due to the pandemic (疫情), the Green Team now conducts their Tuesday and Thursday meetings online. At     6     meetings they come up with ideas and school activities that will teach fellow students and local people to protect the environment in fun ways.

“We volunteer in the community for river cleanup and compost (堆肥) efforts with Kompost Kids,” Clark says. The Green Team is invited to help sort and recycle waste with Kompost Kids, a local nonprofit organization run     7     volunteers.

Kompost Kids     8     (devote) to changing the way people deal with their waste.     9     can you do to help? Kompost Kids and the Green Team suggest you compost organic waste. Recycling plastic, metal cans, newspapers, etc.     10     (be) another great way to help the environment. You can separate these items in bins when throwing them away.

The thought of a natural disaster can be    1    (frighten). But you can prepare your family for it with some simple steps. Below are some common    2    (measure) of preparing for disasters.

Have enough ways to get warnings. There    3    (be) different ways to receive a warning of a disaster. The common ones include using the television, phone, etc. To avoid missing the warning, you’d better make sure you have at least three ways to receive the warning.

Decide how to make family members communicate. Come up with    4    communication plan in case you are    5    (separate) in a disaster. Provide each member of the family with a phone, for example. And make a contact card for each family member so they have the phone numbers and addresses    6    they may need.

Choose    7    least two meeting places. Do it in case all of your family members can’t   reach a designed meeting place. Choose one place in your neighborhood or close to your home as well as one that’s out of town. Consider    8    (meet) at the closer place first in a disaster. And keep the out-of-town place as a backup.

Run practice drills (演习). It’s important    9    (practice) what to do in case of a natural disaster,    10    (especial) if you have children. Each year, you’d better organize a practice drill for a possible disaster. And try to let all the family members take part in it.

Cleaning your plate may not help feed hungry children today, but the timeworn (陈旧的) advice of mothers everywhere may help reduce food waste from the farm to the fork and make it     1    (easy) to feed the world's     2    (grow) population. Hard data is still being collected, but experts in Chicago say that each American     3    (throw) away 33 pounds of food each month, which means everyone throws away almost 400 pounds of food every year. In richer nations, fruits and vegetables end up in the trash because they aren’t pretty enough     4    (meet) standards, and have gone bad in a home refrigerator. In developing countries, much food goes wrong     5     it gets to the market because of poor roads. But the effect of food waste is far     6    the kitchen. Agriculture is the world's largest     7    (consume) of water, a big consumer of energy. No matter     8    sustainable (可持续的) farming is, if the food is not eaten, it means we don’t make good use of our resources.   In     9     (real), the resources we could use have decreased     10    (sharp). All of us have responsibility for it.

Covering 7 million square kilometers of jungle and river over eight countries, the Amazon Rainforest is home to millions of sorts of plants and animals, some of     1     are still being discovered today. It's also the world’s     2    (large) supplier of oxygen and is a treasure chest for medical     3    (researcher) who are experimenting with different plants in hopes of finding cures for certain diseases.    4    , the world is at risk of losing this rich rainforest because of deforestation (滥伐森林)    5     (cause) by the actions of farmers, loggers and settlers.

The Amazon Basin     6    (lose) 20% of its rainforest since 1970. Cattle farmers have     7    (continuous) cleared the land for cows     8    (eat) on and crop farmers have begun “slash and burn” (刀耕火种), a farming method that involves cutting down forests and burning the land to make     9     suitable for agricultural purpose. Loggers have been cutting down the trees for timber(木材), further decreasing its size.

With the destruction of the Amazon Rainforest, global warming becomes more of a threat. It is up to each individual to fight against the     10    (disappear) of the Amazon by making the world know something about this environmental disaster.
