A vegetarian diet（素食）is often praised for its health benefits. Studies have shown that vegetarians usually have lower levels of heart disease and a risk of diabetes（糖尿病）than people who eat meat. What most people are less aware of, however, are the effects that a vegetarian diet can have on the environment.

Researchers from the Union of Concerned Scientists in the US recently studied how consumer behavior affects the environment. The study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicle.

Then, how can eating meat have a negative effect on the environment? For a start, all farm animals such as cows, pigs, and sheep give off methane gas（沼气）by expelling（排出）wind from their bodies. One co w can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide（二氧化碳）. Many environmental experts now believe that it is more responsible for global warming than carbon dioxide. It is estimated that 25% of all methane released into the atmosphere comes from farm animals.

Another way that meat production affects the environment is through the use of water andland.2,500 gallons of water are needed to produce one pound of beef, whereas 20 gallons of water are needed to produce one pound of wheat. One acre of farmland used for crop production can produce 40,000 pounds of potatoes, 30,000 pounds of carrots, or 50,000 pounds of tomatoes.

Many people now see the benefits of switching to a vegetarian diet, not just for health reasons, but also because it plays a vital role in protecting the environment. However, some nutritionists advise against switching to a totally strict vegetarian, or vegan diet. They believe a vegan diet, which excludes（排除） all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.

Henry Norman Bethune was a great  （Canada）doctor with a very creative mind and a determination to help people. As a small boy, he became very interested in medicine and decided to become a doctor. After （graduate）from medical college in 1916, Bethune worked as a doctor in England, the US, and Canada. He reinvented or redesigned over 10 medical instruments （make）them more useful. He is known best for his service during the World War I.

In 1938, Bethune left China, after he heard that many people were dying in the war. the difficult situation, Dr. Bethune did whatever he could -to assist the Chinese people. He helped to organize hospitals, （teach）doctors and nurses, and showed people how to give first aid. He is respected as unique personality in the history of medicine, owing to the materialization of the concept of "mobile medical unit". Some of the surgical tools developed by him （use）in surgeries even now. Sadly, Dr. Bethune passed away in November the following year and was buried in Shijiazhuang. After Dr. Bethune's （die）, Chairman Mao Zedong wrote an article in memory of him, he praised Dr. Bethune as a hero to be remembered in China.

Our neighbors had a loud party last night. We weren't 1 but this was one of those celebrations that I didn't mind. They are a bunch of young, single guys and I would have felt out of place.

What 2 me was the way they behaved. One of the young men came over 3 in the day to "warn" us of the upcoming event and said it would be over at about 11 p. m. That was the first step. Even more 4 was what they did next. "Here's my 5 " offered our neighbor 6 . "Text me if it's too noisy." That was a level of 7 I had never experienced in all my years of being a neighbor!

And it really worked in their favor. My husband and I were so friendly that even when the event went past the 8 end time, even when the music reached high decibels（分贝）, and even when we couldn't get through on the phone number, we felt no 9 . We knew they would stop and be 10 eventually.

It takes such little effort to make people feel that they 11 and get people on your side. Everyone needs to let loose every now and then, especially in these uniquely tough times. But people who do it without 12 others are few and far between. I hadn't fully 13 my neighbors until this week. We had adopted that all too American "live and let live" posture. But now I see them in a new light and with greater 14 . They didn't just bring noise to the neighborhood; they shone the light of 15 .

Climate change refers to long-term shifts in temperatures and weather patterns.  But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas. Climate change can cause extreme events like wildfires and floods. 

How does climate change make you feel? The news of melting glaciers and oil spills may seem overwhelming and can make you feel angry, frightened, hopeless or upset. This is called climate anxiety. If you feel worried about what's happening to the world, it's good for you. It's normal to be upset when things you care about are getting hurt.

 There are lots of things you can do to help society take better care of the world. Turn your fear into power by doing something. Breaking the problem into bite-sized chunks is a good way to start. Think of something you feel passionate about, such as protecting ocean life or saving forests, and join a community group or charity that supports that cause.

Positive action can inspire others too. Sisters Kim and Stella King from the charity Fights Against Plastic have picked up 90,000 pieces of plastic. They ask schools, businesses and organizations to follow their lead. Remember, it's important to get support from people around.

A. Why is there climate anxiety?

B And it is a normal, healthy response.

C. This risks the lives of humans, animals and plants.

D. Melting glaciers contribute a third of sea-level rise.

F No one can fix climate change on their own but we can all play a part.

f. These shifts may be natural, such as through variations in the solar cycle.

G. So, tell friends and family what you're up to and encourage them to join in.

The curb cut（路缘坡）is a convenience that most of us rarely, if ever, notice. Yet, without it, daily life might be a lot harder—in more ways than one.

Pushing a baby stroller onto the curb, skateboarding onto a sidewalk or taking a full grocery cart from the sidewalk to your car—all these tasks are easier because of the curb cut.

But it was created with a different purpose in mind.

It's hard to imagine today, but back in the 1970s, most sidewalks in the United States ended with a sharp drop-off. That was a big deal for people in wheelchairs because there were no ramps（斜坡）to help them move along city blocks without assistance. According to one disability rights leader, a six-inch curb "might as well have been Mount Everest" for wheelchair-bound people. So, activists from Berkeley, California, who also needed wheelchairs, organized a campaign to create tiny ramps at intersections to help disadvantaged people dependent on wheels move up and down curbs independently.

I think about the "curb cut effect" a lot when working on issues around health equality. The first time I even heard about the curb cut was in a 2017 Stanford Social Innovation Review piece by PolicyLink CEO Angela Blackwell. Blackwell rightly noted that many people see equality as "a zero-sum game（零和游戏）". Basically, there is a deeply rooted social belief among them that intentionally supporting one group hurts another. What the curb cut effect reveals though, Blackwell said is that "when society-creates the circumstances that allow those who have been left behind to participate and contribute fully, everyone wins."

One such example is closed captioning（字幕）, originally intended to help deaf people understand movies and TV shows without needing to hear dialogue or sounds. But it's easy to think of other applications for closed captioning: it's convenient for customers watching TV in a noisy bar or gym, second-language learners who want to read as well as listen, or students who use it as a study aid.

So, next time you cross the street, or roll your suitcase through a crosswalk or ride your bike directly onto a sidewalk—think about how much the curb cut, that change in design that broke down walls of exclusion for one group of people at a disadvantage, has helped not just that group, but all of us.
