【题目】Is Your Diet Destroying the Environment?

A vegetarian diet is often praised for its health benefits. Studies have shown that vegetarians usually have lower levels of heart disease and a lower risk of diabetes 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 (沼气) gas by expelling (排出) wind from their bodies. One cow can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide. 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 and land. 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 all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.

Today, many people know it’s important to take better care of their bodies and to use the earth’s resources more efficiently. As this understanding spreads, more people may realize that to help the environment and for the human race to survive, more of us will need to become vegetarians.

2Many figures are used in Para.4 to show ___________.

【题目】Reflect on our relation with nature

UK physicist Isaac Newton once said, “ 1.” Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we break the rules, she is likely to be cruel and lash out (迅猛攻击) at us.

The outbreak of the novel coronavirus pneumonia (NCP) in China and some other countries at the beginning of this year is an example. 2 and probably has an intermediate host. It’s said that the virus originated from the Huanan Seafood Market in Wuhan, Hubei province, where live wild animals were sold.

The Wall Street Journal reported that Dr Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, “This outbreak is a lesson for us. On a global scale (规模), human population density (密度), wildlife diversity, and land use change are what drive new pandemics (流行病).”

In the ancient times, people needed to rely on nature to survive so they held it in awe . For example, the American Indians believed that humans are a part of nature and nature is a part of humans. 3

However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify (改变) plants, capture some wild and odd animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance.

4, Brian Lamacraft at Medium said it’s time for people to “reflect on our relationship with our planet” and “reconnect with this world and everything that we’ve been given”. After all, according to US poet Gary Snyder, “5

A.Nature is not the place to visit. It’s our home

B.Nature is pleased with simplicity and nature is no dummy

C.Chinese ancients always pursued the harmony between nature and human beings

D.It reminds us that the past outbreaks did severe damage to the human society

E.Although we don’t know for sure what first caused the NCP outbreak

F.The new coronavirus is similar to a virus found in a bat in 2017

G.The only mother of human beings are now facing a great threat-environmental problem
