It’s reported that about 20 percent of the Amazon rainforest has disappeared during the past 50 years. Deforestation is not only threatening the millions of unique plant and animal species native to the Amazon River area, it’s affecting humans worldwide. When it comes to the protection of the Amazon, it’s hard for many people to relate because they don’t feel connected to the area. There are actually a lot of direct connections, no matter how far away we are.
A connection that affects everyone on the planet is climate (气候) change. Planting new trees in the forest is basically a way of removing CO2 from the air. Rain forests have a carbon (碳) reduction nearly equal to half of what is in the air. About half of that is in the Amazon. Another case in point is a big snake called the bushmaster that lives in the Amazon. Today, millions of people use medicines made from its venom (毒液) to treat high blood pressure. So they have longer, fuller, and more productive lives.
In the 1960s, there was only one highway in the entire Amazon. That’s an area as large as the continental United States with one highway and three million people. Today, there are between 30 million to 40 million people, countless roads, and about 20 percent forests have been cut down. But on the plus side, 50 years ago there were only two national parks and a national forest and a reserve in Brazil. Today, more than 50 percent of the Amazon is under some form of protection.
“There’s been a lot of damage done and forest lost, but nothing is gone until it’s gone”, noted National Geographic explorer Dr. Thomas Lovejoy. “We want to see more shared planning between the departments of transportation, energy, agriculture, and the other industries in the area. We think Amazon cities can have higher quality of life and keep people in existing cities so there’s less reason to deforest.”

Changing a few old habits can make an impact on your energy bill, your comfort and the environment. Here are some handy tips to make your house more energy-efficient.
Lower the heat
If your home has adjustable central heating, lowering the room temperature even slightly can make a difference. You may not feel it, but your wallet will. It is even more advisable to control temperatures at different times of the day.
Hang clothes out to dry
If the weather allows it, head outside and dry your laundry on a clothesline. The sunlight will help eliminate (除去) bacteria and dust. While clothes dryers get the job done faster, they also use up energy. By hanging your clothes out, you' ll be cutting greenhouse gases by about three kilograms per load.
Take advantage of natural light
Installing (安装) large windows on the northern side of your house can help you make use of sunlight's natural warmth. To stay cool indoors on hot summer days, install blinds (百叶窗) to block the heavy sun. Put your desk near the window, then you don't need a lamp in the daytime.
Wrap (裹) your pipes
Be sure your hot-water pipes are properly wrapped. In an average home, heating water accounts for more than one-quarter of the energy bill. Why let warmth go to waste before it reaches you?
Choose the right size for appliances (家用电器)
When the time comes to replace (更换) appliances, select those that are both energy-efficient and of the appropriate size for your needs. Don' t buy bigger ones just because you can.
1. What benefit may using less energy at home bring about?A.Enlarging your living space. | B.Keeping old habits unchanged. |
C.Having a healthier living environment. | D.Improving your work efficiency. |
A.It gets clothes dry much faster than clothes dryers. |
B.It uses half the energy that clothes dryers do. |
C.It may help to build a greenhouse. |
D.It helps remove bacteria in clothes. |
A.Shades. | B.Windows. | C.Blinds. | D.Curtains. |
A.Proper size. | B.Good quality. | C.Replacing time. | D.Reasonable price. |
Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.
1. It can be concluded from paragraph 1 that _______.
A.the problem of global warming will have been quite solved by 2020 |
B.gas emissions have been effectively reduced in developed countries |
C.the Paris Agreements is more influential than the Kyoto Protocol |
D.humans have made continuous efforts to slow down global warming |
A.The human population would increase by one third. |
B.Little over 50% of all species would still exist. |
C.Nations would not need to tighten their emissions targets. |
D.The Agreement’s minimum goal would not be reached. |
A.0.8℃ | B.1.5℃ |
C.2℃ | D.3.5℃ |
【推荐3】According to a new USDA(the U.S.Department of Agriculture)report,U.S.forests could worsen global warming because they are being destroyed by natural disasters and are losing their ability to absorb planet-warming gases as they get older.The report predicts that the ability of forests to absorb carbon will start declining after 2025 and that forests could release up to 100 million metric tons of carbon a year as their emissions from decaying(腐烂)trees go above their carbon absorption.Forests could become a“substantial carbon source”by 2070,the USDA report says.
The loss of carbon absorption is driven in part by natural disasters such as wildfires, tornadoes and hurricanes,which are increasing in frequency and strength as global temperatures rise.The disasters destroy forestland,destroying its ecosystem and decreasing its ability to absorb carbon,according to Lynn Riley,a senior manager of climate science at the American Forest Foundation.Aging forests also contribute.The report found that older,mature trees absorb less carbon than younger trees of the same species,and U.S.forests are rapidly aging.
This trend is likely to continue,as forests come under increasing threat from climate change and exploitation(开采).The typical tropical forest may become a carbon source by the 2060s,according to Simon Lewis,professor in the school of geography at Leeds University. “Humans have been lucky so far,as tropical forests are cleaning up lots of our pollution,but they can’t keep doing that indefinitely,”he said.“We need to cut down fossil fuel emissions before the global carbon cycle starts working against us.”
U.S.forests currently absorb 11 percent of U.S.carbon emissions,or 150 million metric tons of carbon a year,equal to the combined emissions from 40 coal power plants,according to there port.The loss of forests as natural carbon absorbers will require the U.S.to cut emissions more rapidly to reach net zero.“As we work to decarbonize(碳减排),forests are one of the greatest tools.If we were to lose that tool,it means we will contribute that much more in emissions,”Riley said.

【推荐1】Want to get your package delivered via robots? Now there’s an app for that. If you live in Washington D.C., or Redwood, you may have glimpsed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many curious onlookers.
The autonomous machines were part of a pilot program last year by Starship Technologies focusing on delivering meals from local restaurants in dozens of cities around the world. This week, the company unveiled plans to broaden its delivery service beyond food to include package, a move that led it to declare itself “the world’s first robot package delivery service”. The next time you order food, this cute robot might roll up to deliver it. The package delivery service is not available to everyone yet.
The wheeled robots have a top speed of 4mph and can detect obstacles from 30 feet away. “The robot can operate through anything,” Nick Handrick, head of operations for Starship’s D.C. office, sad, “If you had something in the way-a stick –it’s able to climb sticks.”
To sign up for the service, which costs a little more than $10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address”, a unique address inside a Starship facility, where they can have package sent from places such as Amazon.com. Once a package is delivered to the Starship address, customers receive a text notification that allows them to schedule a home delivery via robot. The robots are opened by customers via a mobile phone code.
Barriers exist for robotic ground delivery, with many states requiring that humans be in control of delivery robots. Those regulations haven’t stopped Starship Technologies from accumulating experience on streets around the globe ahead of the company’s latest launch. The company says its robots have covered more than 125,000 miles in more than 100 cities in 20 countries.

【推荐2】Recently, 16 Chinese online novels have been added to the collection of the British Library for the first time, including The Era of the Earth, The First Order, Great Doctor Ling Ran, and Great Power, Heavy Industry. Covering themes of science fiction, history, reality and fantasy, these works are considered the classics of Chinese online literature from the past 20 years.
One of the largest research libraries in the world, the British Library houses more than 170 million items, including the cultural relics of different civilizations from throughout history. The library usually selects works based on their popularity or by considering an item’s value. Readers can check the information about the 16 books on the library’s website, and borrow printed copies.
As one of the current pillars(支柱)of mass cultural consumption, which began with “fast food” romances, fantasies and mysteries-enjoyable to consume, but not intellectually nutritious, the Chinese online literature industry has quickly matured during its fast development over the last two decades.
In recent years, online novels have received increasing acknowledgment from home and abroad. In 2019, 10 online novels, including Great Power, Heavy Industry, were added to the collection of the Shanghai Library, and between 2020 and 2022, 144 online novels like Battle Through the Heavens and Lord of Mysteries were entered into the collection of the National Library of China.
Great Power, Heavy Industry tells of how China’s manufacturing industries have grown stronger in recent decades, and foreign readers can learn about the Chinese system and culture behind the country’s swift economic development, getting to know China better in the process, the author, whose online pen name is Qicheng, says.
In recent years, Chinese online literature has attracted an increasing number of readers from overseas. One of the largest online literature platforms, China Literature Group, has authorized the digital and print copyrights of more than 800 online novels to overseas markets.

【推荐3】“Cook for yourself like you would for a guest.” This advice comes from Claire Lower in an article for Lifehacker. It seems to be good advice for people who live alone and can’t be bothered to cook delicious food when there’s no one else to enjoy it. Yes, they can gorge themselves on popcorn and call it a night without fear of judgment, but Lower argues that this “wears on the soul” over time.
Every meal is a chance to work on good table manners, including the art of dinner conversation, eating tidily, and using cutlery properly. You can try to use nice dishes and real glasses in order to create an appealing atmosphere that encourages everyone to take the meal more seriously.
At the same time, it is a parental duty to cook a range of interesting and delicious meals to help train children for the unavoidable day when they actually are at a fancy restaurant or a friend’s house and faced with a strange soup, an unusual salad, or an unrecognizable main course. That way, they’ll know what to do and how to do it politely.
Eating gives shape and meaning to our days, not to mention flavour, nutrition and energy. Just as boring, repetitive meals wear on the soul, delicious ones can bring happiness, hopefulness, and peace. So, don’t give up on cooking well, whether it’s just for you or for a group of children, even if it’s just a few times a week and the dishes are simple. It does get easier and better, and you’ll learn to look forward to it.
