Mother earth is a place where     1     species can coexist. Unfortunately, wild animals have no place in the 21st century. Some people think that protecting these wild animals is a waste of     2    . But an increasing number of people come to realize that the disappearance of animals will result in a serious threat to     3    . It is hard to imagine what our world would be like without animals. There are enough farm animals providing us with sufficient and nutritious meat. Therefore, we don’t need to make use of wild animals, especially the     4     ones. To protect animals is to protect our living environment. So great efforts should be made by every     5     to keep the diversity of animals.

What Can You Do with Used Coffee?

It’s the most popular drink worldwide. According to the British Coffee Association, approximately two billion cups of coffee are consumed every day. But after the beans have been picked, roasted and brewed, the grounds are often     1     of as waste. With the environment and resource consumption such hot topics at the moment, wouldn’t it be great if we could reuse this waste to make something useful? Well, you can.

The company OCHIS manufactures sunglasses. Max Havrylenko, founder of the company, was searching for a(n)     2     substance to plastic. He wanted to “solve the problem of plastic use and overconsumption”, he told the BBC. OCHIS fuses the grounds with vegetable oils, forming a bond. These are pressed into plates which are     3     and flexible. These are then cut into the arms and frames of the glasses. “Don’t worry,” he says. “They won’t     4     in the rain.”

Rosalie McMillan, a London jeweller, uses recycled coffee grounds along with gold and silver to make     5     jewellery. She mixes the coffee with oils and     6     it to heat and pressure to create a compound she calls “Curface”. Her website claims it has a “beautiful surface quality and texture” with similar     7     to hardwood.

What about a coffee cup made from them? Kaffeeform is a German-based company that transforms used grounds and renewable plant-based raw materials into a durable composite. This is     8     into a variety of containers and polished and finished, ready to be sold. So, you can drink your coffee from a cup made of coffee.

And it doesn’t stop there. Even without a factory, you can make use of coffee grounds. They     9     excellent fertilizer. You can mix them with water to make a sepia-toned paint. And the     10     goes on. So next time you finish your morning cup, save the grounds.

The measures were effective. Up to now, the antelope population     1     and in June 2015, the Tibetan antelope     2     from the endangered species list. The government, however, does not     3     to stop the protection programmes, since the     4     to the Tibetan antelope have not yet disappeared.

Standing in line at the grocery store last week, I watched the woman in front of me buy a tube of toothpaste. As the clerk placed her     1    in a plastic bag, I couldn’t help wondering how long it would take for that bag to end up in the trash. Then I noticed the big purse the woman was carrying and wondered why she had needed a plastic bag at all.

People have come to rely on plastic bags as everything from shopping bags for groceries to     2    bags. Although plastic bags can be recycled, only about one percent of those used in the United States are. Instead, after helping people     3    items from one place to another, most are thrown away. They end up in landfills, where it can take a plastic bag up to a thousand years to decay. Some bags end up     4    in the environment, sticking to trees and fences, blocking rivers and oceans, or floating along city sidewalks.

Plastic bags harm the environment in several ways. First, they break     5     into particles that pollute our soil and water. Because most plastic bags are made of polyethylene, a product derived from crude oil(原油)or natural gas, they waste     6    resources. Plastic bags can also harm animals. Scientists estimate that more than one million sea animals, including whales, seabirds, and turtles, die each year from     7    or becoming stranded in plastic.

People all over the world are starting to recognize the problems associated with plastic bags. Countries such as China, South Africa, Switzerland, and Uganda are taking action and banning the bags. Other nations, including Italy and Ireland, have been trying to     8    the use of plastic bags by     9    them. In the United States more and more communities are ridding themselves of plastic bags. Now more and more people are also purchasing inexpensive,     10    bags and using them whenever they shop. If we all take this simple step, we can be a part of a “green” revolution.

Air pollution triggers (引发)more heart attacks than using cocaine and poses as high a risk of sparking a heart attack as alcohol, coffee and physical exertion, scientists said on Thursday. Anger, marijuana (大麻)use and chest or respiratory (与呼吸有关的)     1     can also trigger heart attacks to different extents, the researchers said, but air pollution,       2     in heavy traffic, is the major cause.

The findings, published in The Lancet journal, suggest population-wide       3     like polluted air should be taken more       4     when looking at heart risks, and should be put into context besides higher but relatively rarer risks like drug use. Tim Nawrot of Hasselt University in Belgium, who led the study, said he hoped his findings would also encourage doctors to think more often about population level risks.

Nawrot’s team combined data from thirty-six       5     studies and calculated the relative risk posed by a series of heart attack triggers and their population-attributable fraction (PAF)—in other words the proportion of total heart attacks estimated to have been caused by each trigger. “Of the triggers for heart attack studied, cocaine is the most likely to trigger an event in an individual, but traffic has the greatest population effect as more people are       6     to it,” the researchers wrote. “PAFs give a measure of how much disease would be avoided if the risk was no longer       7    . ”

A report published late last year found that air pollution in many major cities in Asia exceeds the WHO’s air quality guidelines and that poisonous       8     of pollutants result in more than 530,000 earlier deaths a year. While       9     smoking was not included in this study, Nawrot said the effects of secondhand smoke were likely to be similar to that of outdoor air pollution, and noted previous research found that bans on smoking in public places have       10     reduced heart attack rates.
