Earth Day is an event    1    (annual) celebrated on April 22.     2    (found) by Senator Gaylord Nelson, an American politician and environmentalist, it was originally aimed at helping the public to know the current situation of air and water pollution and    3     (get) people to care about the earth.

In1962, Rachel Carson’s bestselling book “Silent Spring” created an    4    (aware) of the dangerous effects of pesticides (农药) . Then, a fire,     5     broke out in 1969 on Cleveland’s Guyahoga River, shed light on the problem of chemical pollution in water. Senator Gaylord Nelson dreamed of    6    similar large event that would get people to take environmental issues seriously. In 1969, he was inspired by protests against the Vietnam War and came up with the idea for Earth Day.

In the fall of 1969, Nelson announced it and appealed to the entire country to get involved. Consequently, telegrams, letters and telephone calls    7    all over the country poured in. Since 1970, Earth Day celebration have grown. Later, Nelson    8    (award) the Presidential Medal of Freedom in recognition of his work.

Today, Earth Day is celebrated around the world every April 22. Sometimes numerous communities celebrate Earth Week, an entire week of    9    (activity) focused on the Environmental issues. In 2017, the March for Science    10    (occur) on Earth Day(April 22, 2017) and was followed by the People’s Climate Mobilization (April 29, 2017).

Today, we buy more clothing than we did 20 years ago. Waste     1     (cause) by fast fashion has become a serious problem. That's a lot of waste if you take into     2     (consider) the fact that a lot of water     3    (use) to produce one T-shirt. What can you do about that? Use the principle“less is more”.

Fast fashion clothing is designed to fall apart fast,     4     means that you'll need more soon. In the long run, it's     5     (cheap) to buy fewer clothes of higher quality. Besides, more and more stores have recycling programs,     6     (make) it easy to get rid of unwanted items responsibly.

Businesses can be environmental-friendly, too. For example, an online clothing store promises     7    (contribute) 5% of its income to     8     organization which protects elephants in Africa.     9     (actual), shopping in such similar businesses is certainly an     10     (amaze) way to be in harmony with nature. It creates a win-win situation where you can buy things you love, and at the same time, the environment has been improved because of your effort.

Environment-friendly ideas have been created to supply people with helpful     1     (tip) on how they can help the environment     2     well as save money. I honestly believe that everyone wants to help the environment, even if they do or do not believe in     3    （globe）warming.

With power bills, water bills and all other expenses     4     (continue) to rise, it’s very hard for the average worker. No matter what your financial position is, there is always something everyone can do     5     (help) save our environment. We are not the only ones that live on this     6     (amaze) planet. We also share it     7     a wide range of strange and wonderful animals. It would be a great tragedy if they     8     (be) not around for our future generations to enjoy. Every little bit helps, so please do all     9     you can to protect our environment and the environment of these surprising animals.

I hope these environment-friendly ideas can help everyone to do     10     (they) bit for the environment and to make this world a better place.

Amsterdam has decided to remove gas vehicles (机动车) from the roads. By 2030 only non-polluting vehicles will be allowed in the streets. The Netherlands     1    （make）great efforts to protect the environment since the 90s.The Clean Air Action Plan,     2     is aimed at removing polluting vehicles from the city, is the newest measure. The new policy is important because air pollution in the Netherlands is above European standards,     3    （cause）risks for respiratory（呼吸的）illnesses. "Pollution is often a silent     4    （kill）,”said Ms. Sharon Dijksma, who is responsible     5     the city's traffic.

The city will stop using gas vehicles gradually and increase the use of cleaner vehicles. Charging stations    6    （offer）to those who buy electric vehicles. Fund and special parking permits will     7    （probable） be provided to encourage the use of environmentally friendly cars. In Netherland, 30percent of commuter（通勤者） travel by bike.     8    , cars are still major sources of particle matter pollution.

That is     9    they plan to ban all polluting cars.

Hopefully, this policy will encourage other cities to ban polluting vehicles as well. In fact, Brussels is already considering     10    （adopt）the policy.

It is sad but true that people die in earthquakes      1      falling furniture and bricks. Earthquake     2       (safe) is very important and there is more to it      3     just keeping buildings from falling down. So if your home is in an earthquake area, you should prepare carefully before the earthquake     4      (occur).

First, make sure you buy a house which is safe during the earthquake. All pipes should be fixed to the walls and all walls should be     5     (especial) thick and strong. Make sure the building has no     6     (break) windows and is well repaired.

Second, look at the objects in your house. Objects      7     computers, televisions and lamps can be tied to tables or     8      (stick) to them so they won’t easily move around. The cupboards,      9     many small things are stored, should have strong doors. Always remember,     10      (good) safe than sorry.

Environmental problems are significant in many people’s minds, but it’s     1     younger generation who is particularly concerned about the future of our planet. From global school strikes for climate change action     2     teen activists (积极分子), kids are now taking it into their own hands.     3     (inspire) this love for the earth, a new law that requires students to plant 10 trees each before graduation was passed in the Philippines on May 15, 2019. In the past years, the Philippines, an Asian country,     4     (lose) more than 30% of its forest cover. Luckily, 175 million trees could be planted by students each year under the     5     (fantasy) program. The action of planting 10 trees is extremely easy for the average student,     6     their easy and small actions will add up quickly to work wonders.

In fact, this isn’t the only positive program     7     (involve) the younger generation. Some schools in India made students pay their “school fees” by collecting and recycling any plastic waste     8     was lying across the town. This activity has raised the     9     (aware) of plastic waste in Asian countries. Besides, most students there are making school life greener by removing the plug from     10     (it) power supply instead of just turning off the device, such as the computer in the classroom.

With the     1    (develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because     2     air pollution.

Air pollution is caused by the following     3    (reason): about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off     4    (poison) gases. 25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health     5     to others.     6    (beside) these, about 10% of air pollution is caused by other reasons.

We should take some measures to fight     7     pollution. New fuel can be used to take     8     place of gas. We can plant more trees. If everybody realizes the     9    (important) of the environment and does something to stop pollution, the problem will     10    (solve)．
