World Ocean Day is an international day that takes place annually on 8 June. It is observed as a     1     (remind) every year of the destruction     2     (cause) by human activities like garbage and waste water treatment and oil leaks. This year the main purpose of the Day is to inform a     3     (wide) public of the impact of human actions     4     the ocean, expecting more people     5     (care) about the worsening situation.

The Day is now celebrated in over 100 countries with hundreds of special events broadcast across the globe. It     6     (mark) in a variety of ways, including launching new campaigns and holding special events, to advance ocean conservation and education.

Young people are an important part. The Day provides them with a platform     7     they can express their concerns and share their ideas. Each year, the Day has a theme for the campaigns and events. For example, in 2016 and 2017 the themes were “Healthy oceans, healthy planet” and “Our oceans, our future”,     8     (respective). “Collective Action for the Ocean” is the theme in 2022,     9     (throw) light on the communities, ideas, and solutions that are working together to protect     10     recover the ocean.

A Norwegian company has created what it calls the world’s first zero-emission, automatic cargo ship. Developed by chemical company Yara International, the ship     1     (design) to reduce emissions of pollutants and greenhouse gases, and move goods away     2     roads to the sea.

The shipping industry accounts for between 2.5% and 3% of global greenhouse gas emissions, according to the International Maritime Organization. Nearly all of Norway’s electricity is generated by hydroelectric power, which is     3     (general) considered to have much lower carbon emissions than burning fossil fuels,     4     it still produces greenhouse gases.

Capable of carrying 103 containers and with     5     top speed of 13 knots, it will use a 7 MWh battery, with about a thousand     6     (time) the capacity of one electrical car. The ship will be charged near the port before sailing to container harbors along the coast and then back again,     7     (replace) 40,000 truck journeys a year.

As well as     8     (provide) a greener option compared to conventional cargo ships, there is no crewman, which means it will be more cost-effective to operate. Initially, loading and unloading the ship will require humans, but gradually, all loading, discharging, and some other operations will also be eventually operated using technology. That will involve developing     9     (autonomy) cranes and carriers, which are the vehicles     10     place containers onto ships.

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     (factor): 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     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 environment and does something to stop pollution, the problem will     10     (solve).

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).

More and more children are suffering from eco-anxiety, which is     1    problem that causes people to worry a lot about the future of Earth and the life on it. They worry about climate change,    2    (pollute) and the loss of biodiversity. This has urged education experts     3    (call) for more teaching in schools about climate change, wildlife and the environment. So necessary is knowledge of them nowadays     4    experts believe it should be taught to all year groups.

The Teach the Future campaign finds that only one in four schoolchildren    5    (feel) they know enough about the climate crisis. It says this is leading to move children    6     (struggle) with eco-anxiety and worrying about the planet. A conservation organization, Earth Rangers,    7    (take) action to address the problem of eco-anxiety since it noticed that.

It says, Eco-anxiety does have a big effect    8    children in many ways. This includes feelings of fear and hopelessness. It is    9    (importance) to research and understand the ways in which we can help children deal with these feelings     10    (effective). In the meanwhile, schools should create conservation activities and help children teach their parents how to protect nature.
