2 . Understand your pet's body language

Body language is different depending on what sort of animal you have chosen as your pet.    1    Understanding your pet's body language will help you to be a better communicator, as you can even copy some of its movements, expressions and sounds to send your message in a way it understands.

●     2    If your dog isn't looking directly at you, but is looking out of the corners of its eyes so that you see a lot of the whites of the eyes, it might be about to have an aggressive outburst. If your dog is feeling stressed or aggressive, its wide eyes will be accompanied by a rigid(绷紧的)body.

●If your cat looks at you and blinks at you slowly, it's likely communicating affection.    3    For cats, closing one's eyes in the presence of another is a way to show trust. If your cat feels threatened, its tail will likely be upright; its back will likely be arched, too.

●    4    If your bird's pupils (   瞳孔) enlarge and shrink rapidly, this can be a sign that it's excited or greatly interested, or scared or angry.    5    Birds will shake their feathers while cleaning themselves ; if their feathers remain shaking, however, this could mean they’re unwell, in which case, take them to an animal doctor for a checkup.

5 . E-waste is fast becoming a serious problem around the world. This report will examine this problem and provide some possible ways to solve it.

    1     It is often cheaper to buy new products than to repair old ones. Also, through clever advertising, companies always encourage people to change their old TVs, mobile phones and computers for the latest models. E-waste is created when we throw away old ones. In the EU alone, about 8,700,000 tons of e-waste is produced each year. Sadly, just over 1,000,000 tons is recycled. Burying (填埋) e-waste or burning it cause serious problems for the environment.     2     These things can then get into the ground or pollute the air when they are burnt.     3     However, their plans are not always managed properly. Sometimes electronics are just sent to poor countries such as Ghana. Here they are often burnt in public areas, which is very bad for people’s health, Setting up recycling centers is a good way to solve this problem. E-cycling centers could recycle the parts that can be reused and deal with the rest properly.     4    This means that producers must take back old products. They should then make sure old products are properly recycled or reused. As for us, we should try to cut down on e-waste.     5     And don’t buy a product just to have the latest model. E-waste is a serious problem in the modern world. Both producers and users must take actions and try to keep it to the smallest amount.

6 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush（灌木丛）in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.

Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy（树冠层）of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.

Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.

They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity（湿气）of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

7 . A new study published this week in the journal Nature Communications has concluded that a 100 percent change to organic (有机的) food production in England and Wales would actually lead to a great increase in greenhouse gas emissions (排放). In turn, this would contribute to further climate change.

Although organic farming directly pours out fewer emissions than conventional farming—around 20 percent lower for crops and 4 percent for farm animals—it produces notably less food. As to this study’s findings, total organic agriculture in England and Wales would produce 40 percent less food. With less food in the market, the countries would need to increase food imports, which would produce more global greenhouse gas emissions.

Organic farming also increases the amount of absorbing carbon, a process where carbon dioxide (CO₂) is “absorbed” out of the atmosphere and captured by plants and stored in the soil. However, even a total change to organic farming would only be equal to a tiny part of the higher emissions from overseas land use.

“We predict a drop in total food production of 40 percent under a fully organic farming process, compared to conventional farming, if we keep to the same national diet,” Dr Adrian Williams, lead author and reader in Agri-Environmental Systems at Cranfield University, said in a statement. “This results from lower crop quantity, because output is limited by a lower supply of nitrogen, which is mainly from other crops or solid waste from cattle on the grassland.”

Nevertheless, it is important to note that organic farming still holds some useful benefits for the environment, such as reducing exposure to chemicals and improving the varieties of creatures. In conclusion, the study suggests that organic farming will continue to play a key role in resolving the world’s environmental problems. However, it’s just one part of a much wider solution.

8 . Changing weather pallerns, stronger storms, longer droughts- these are just a few signs that our climate is changing rapidly.

Recently, lawmakers in New Zealand signed the Zero Carbon Bill, which lays out a path for the country to reduce its carbon emissions to zero by 2050.

Net-zero is the balance between the amount of greenhouse gases a country releases into the atmosphere and how much is removed from the atmosphere.

A reasonable way to achieve net-zero is to divide the goal into two parts. To reduce emissions, countries can gradually adapt their economies to be less carbon dependent. This can be done by developing renewable energy, improving transportation and food production, stopping deforestation and restoring lands, reducing food wastage, and consuming less meat.

Countries can then address remaining emissions with carbon removal, a process that removes greenhouse gases directly from the atmosphere. This can be done by planting more trees and developing technologies that capture and store carbon.

New Zealand’s Zero Carbon Bill aims to reduce fossil fuel usage and replace it with renewable energy sources. The government has also focused on promoting electric vehicles, public transportanon, biking, and walking. Additionally, New Zealand is committed to planting 1 billion trees by 2028.

The country wants to include agriculture into its climate solution. The government will tax farmers who do not decrease their carbon emissions by 2022. Currently, agriculture in New Zealand accounts for over half of its greenhouse gas emissions.

Methane is a greenhouse gas produced by the decomposition of organic matter from crops and livestock such as sheep and cattle — known as biogenic (生物的) methane. New Zealand will reduce biogenic emissions by 10% before 2030 and between24% to47% before2050. Here , the country is being denounced for not doing enough as methane is a much stronger greenhouse gas, even though it does not stay in the atmosphere as long as carbon dioxide.

Sixty countries have already committed to net-zero, yet they only make up 11% of global emissions. We need convince our leaders that our planet cannot survive if we don't take action.

10 . Coffee chains create a lot of waste, from disposable take-away cups to the used grounds that are sent to landfills. Starbucks has started to try recyclable alternatives to the disposable cups. But the used coffee is often unnoted.

The world drinks around 2 billion cups of coffee a day, producing 6 million tons of used grounds every year. When they go to landfills, the grounds release greenhouse gases into the atmosphere, contributing to global warming.

UK Bio-bean has found a way to turn that waste into a valuable resource. At Bio-bean, used coffee grounds are processed to remove paper cups or plastic bags, and then passed through a dryer and a further screening process. They are finally processed into the fuel. Coffee Log.

"Coffee is highly calorific and lends itself to being a really fantastic fuel," says May. director of Bio-bean. "They burn about 20% hotter and 20% longer than wood logs do."

While these fuels release greenhouse gases when burned, if they replace other carbon-based fuels. Bio-bean estimates that the recycling process reduces emissions （排放）by 80% compared with sending the grounds to landfills.

Founded in 2013 Bio-bean grew rapidly,   launching coffee collection services across the UK and building the world's first coffee recycling factory only two years later. In 2016 they launched their first product,   Coffee Log, and are now ready to launch their first natural flavouring ingredient into the food and drink industry.

“We've really managed to succeed with our innovation because we've managed to get to scale. What started as a good idea is today the UK's largest recycler of coffee grounds. We are turning 7,000 tons of those grounds per year into the fuel," says George May. "Despite being delayed by the COVID-19, we plan to expand our operation into northwestern Europe within the next five years."
