2 . With the outbreak of the COVID-19, multiple kinds of protective medical equipment, such as disposable(一次性的)masks, have been consumed. Market research indicates a sharp increase rate of 53% in the mask market alone. People often use these types of protective equipment and then throw them without thinking of the consequences, both on the ecosystem and human beings.

Disposable surgical masks are severely affecting the ecosystem. When improperly-handled masks enter the water system, they break up into smaller pieces. Complete masks can trap marine animals, resulting in their impaired mobility and even death. Meanwhile, the poisonous plastic particles will cause marine animals to be poisoned to death or weakness when they consume plastic. Furthermore, these harmful pollutants can severely affect reproduction, growth, and the development of the young. Just like their effects on marine animals, these pollutants can also contribute to severe harm in human bodies, especially in the neuron system. Exposure to micro plastics may cause particle poisoning, cellular damage and neuro-degenerative (神经退化的) diseases like Alzheimer’s disease(阿尔茨海默症).

Despite the potential harm to the ocean system and human neuron system, improperly-handled disposable masks will likely become a dangerous public health threat under the environment of a global pandemic. Instead of helping us fight against the COVID-19, to some extent, micro plastic pollution also causes the potential risk of speeding up the spread of the virus. Micro plastic particles in the ocean can be mixed up with water vapour to form aerosols in the atmosphere because they are small enough to enter the water cycle, where they are transferred from the marine system to the atmosphere in vast amounts and become a source for the disease COVID-19. thus causing the virus to speed up the spread of the global pandemic.

Humans will eventually suffer from the wrongdoing in the ocean systems because humans are nothing but temporary residents of the planet. Just like what the famous English anthropologist, Jane Goodall, has said, “Every individual matters. Every individual makes a difference.”

3 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Last month Hong Kong officers found 131,000 kilograms of broken computers, TVs and phones     1     (send) from Japan.

Things like these are called ewaste. Dealing with them is not     2     easy job because dangerous poison can be found in them. Every time an old computer breaks down, it needs to be dealt with     3     (safe). What is worse, at present, broken computer parts are usually buried. It may be     4     (hundred) of years before they are really gone in the earth. Many places in China are polluted by ewaste. Guiyu in Guangdong province is one of     5     (they). It has to deal with 1. 5 million kilograms of ewaste each year, from     6     it makes 75 million yuan. But it comes     7     a cost. Much of the poison in ewaste finds its way into the environment

Luckily, the Chinese government presents a new environmental protection law, the     8     (strict) one we have ever had. Computer companies like Lenovo and Dell will be required     9     (take) back their old computers. Hopefully, the problem with ewaste     10     (solve) in the near future.

4 . Carbon dioxide makes up less than one percent of the Earth’s atmosphere. But the gas is very important to life on Earth. Scientists are finding that processes involving carbon dioxide affect our climate in ways that are difficult to understand. Last month, a committee of the National Academy of Sciences in Washington released a report. It confirmed that increased about six-tenths of a degree Celsius in the last one hundred years. The report also confirmed evidence that the level of carbon dioxide is increasing.

The best information about climate in the past comes from tests of ice many kilometers deep in Antarctica and Greenland. The tests show changes in temperature during the past four-hundred-thousand years. These tests show that levels of carbon dioxide today are the highest ever measured. These findings have led scientists to believe that carbon dioxide is a major cause of climate warming.

Carbon dioxide is released into the atmosphere when fuel is burned. Oil, coal and wood are all fuels that release the gas. When biological waste breaks down, it also releases carbon dioxide.

However, plants use carbon dioxide in the process called photosynthesis. This process provides food for almost all life on Earth. Some groups that support burning oil and coal want to increase the amount of carbon dioxide in the atmosphere. They oppose international efforts to control carbon dioxide.

Some scientists believe that forests and trees are able to capture large amounts of carbon dioxide from the air. Some groups even suggest carbon dioxide could cause plants to grow faster.

A recent study in North Carolina found that more carbon dioxide in the air could cause trees to grow faster. But the researchers found the effect appears to last for only three years. Another study showed that much of the carbon dioxide that is taken in by trees is released within three years. The study noted that leaves release carbon dioxide when they fall from trees and break down in the soil. Plants also naturally release carbon dioxide through the process of respiration.

The natural balance of gases in the atmosphere is a complex scientific issue. The debate over carbon dioxide is only one part of efforts to understand world climate change.

1. The committee report of National Academy of Sciences in Washington reveal that________.

A．ice from Antarctica and Greenland is appropriate to show the change

B．carbon dioxide is released mainly from the fuel

C．level of carbon dioxide increases with global temperatures

D．carbon dioxide is helpful for tree growth

2. According to this passage, those people disagree with the control of carbon dioxide because________.

A．they think that carbon is beneficial for plant growth

B．they want to use more fuels that can emit carbon dioxide

C．they think carbon dioxide is not the main reason for global warming

D．they think it will destroy the natural balance of gases in the world

3. The word “issue” in the last paragraph can be replaced as ________.

A．organ	B．topic
C．publication	D．result

4. Those studies carried out in North Carolina suggest that ________.

A．trees’ function for absorbing carbon dioxide is limited

B．carbon dioxide is the main cause for global warming

C．leaves falling from trees can emit more oxygen

D．more carbon dioxide is beneficial for trees’ growth for many decades

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The water is sitting in around 1000 tanks at the former nuclear power station, but the amount is growing    1    (day) as rainfall and groundwater    2    (enter) the site continue to be polluted. With an average of 160 tonnes a day being added last year, the International Atomic Energy Agency expects existing capacity will be full by mid-2022.

That is     3     the Japanese government is reportedly going to approve a strategy    4    discharging the water to the ocean, as    5     (recommend) by scientific advisers. The release would start in around 2022 and continue for decades.

The news sparked immediate     6     (complain) from Japanese fishing groups and covering warnings that China    7    (ban) Japanese seafood imports. But are people right to be worried about the    8     (environment) and health effects of releasing such a large amount of contaminated water?

Much of the existing water     9     (filter) already by a process designed to remove more than 62 radioactive contaminants. The Japanese government and Tokyo Electric Power Company (TEPCO), the firm    10    runs the site, have emphasized that the main radionuclide(放射性核) remaining is tritium(氚). Francis Livens at the University of Manchester, UK, says this is very hard to separate because it is a radioactive isotope(同位素) of hydrogen, and so part of the water molecules themselves.
