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 .
