Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano(火山) broke out. The hot liquid rock piled higher and higher and spread wider and wider. In this way, an island rose up in the sea.As time went on, hot sun and cool rains made the rock split and break to pieces. Sea waves dashed against the rock. In this way, soil and sand came into being.Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch, In sects couldn’ t stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.The order of coming into being on the island is（）A. soil, plants and animalsB. soil, little creatures and plantsC. soil, birds and plantsD. soil, human beings and animals

The major drivers of climate change are collective enterprises such as power grids（电力公）industry，large-scale agriculture and transportation systems.About half of all greenhouse gas emissions comes from electricity generation and industrial fossil-fuel use.Substantial（大量的）emissions reductions in these settings most likely will not come from personal actions；they will come from laws and policies such as carbon-pricing systems，revised building codes and supports for green investment.But one effective act is to consume less meat. Cutting meat consumption is a powerful and personal thing most Americans can do to tackle（解决）the climate crisis，and they can do it immediately.About4 0 percent of greenhouse gases come from agriculture，deforestation and other land-use changes.Meat-particularly beef--drives climate change in two ways：first，through cows' emission of methane（甲烷），a strong greenhouse gas，and second，by destroying forests as they are changed into grass land.Despite the economic slowdown caused by the COVID-19 pandemic（流行病），atmospheric greenhouse gas levels continued to rise in2020，in large part because of an emissions increase in the Amazon as rain forests were changed into land for cattle to satisfy the global demand for beef.By eating less beef，we can start to decrease that demand. You do not have to become a vegan（素食主义者）to do this.According to one recent study，if every person in the U.S.cut their meat consumption by 25 percent，it would reduce annual greenhouse gas emissions by 1 percent.That might not sound like a lot，but it would help protect the rain forest，so the positive effects-including reduced water and fertilizer use，improved biodiversity and safeguarded rights of local peoples-would be amplified（放大）. Perhaps，social action is kind of infectious（有感染力的）一in a good way，If lots of us begin to eat less meat and if we talk about it constructively，we will likely influence others.Pretty soon the 1 percent reduction becomes 2 percent or more.Reduced demand for meat could motivate my local supermarket to carry better produce，making it easier for me and my neigh hours to prepare a few more satisfying meat-free meals.Ultimately changes in demand will influence industry.Forty years ago few mainstream supermarkets carried organic（有机的）products；now nearly all do.Consumer demand did that. Above all，cutting back on red meat also has the added benefit of being good for your health.（1）What may substantially reduce greenhouse gas emission？ ____ A.Encouraging personal efforts.B.Making favourable laws and policies.C.Reducing various power plants.D.Investing large transportation systems.（2）What caused greenhouse gas level still to rise in 2020？ ____ A.The effects of COVID-19 pandemic.B.The slow pace of economy.C.The destruction of forests for cattle.D.The quick development of agriculture.（3）"Organic products"was mentioned in paragraph4 to ____ .A.remind people to buy organic foodB.prove one's action can influence othersC.call on supermarkets to sell organic productsD.show demand has impact on production（4）Which can be a proper title for the text？ ____ A.Less Beef，Much Healthier.B.To Eat Less Meat for Climate.C.Small Personal Actions Have a Big Impact.D.Cattle Are Partly Responsible for Climate Crisis.

Why is it that the more connected we get, the more disconnected we feel? Every advance in communication technology is a step back from the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine. As almost every imaginable contact between human beings becomes automatic by machine, the alienation question goes up. You can't even call a person to get the phone number of another person anywhere. Directory assistance is almost always fully automatic by machine. Pumping gas at the station? Why say good morning to the worker when you can use your credit card at the pump and save yourself the bother of human contact? Placing money at the bank? Why talk to a clerk who might live in the neighborhood when you can just put your credit card into the ATM? Pretty soon you won't have the hard task of making eye contact at the grocery store. Some grocery chains are using a self-scanner so you can check yourself out, avoiding those annoying clerks who look at you and ask how you are doing. 66. The writer's attitude toward advances in communication technology may be described as ________. A. unconcerned B. critical C. positive D. uninterested 67. If his mom has a question, he will ________. A. find new ways to reach her B. locate her e-mail address C. try to get her a voice machine D. leave her the answer through voice mail 68. Judging from the context, the word "alienation" (Line 2, Paragraph 2) means ________. A. relationship B. closeness C. strangeness D. stress 69. With the rapid development of high technology, people don’t need to ________. A. see or talk to one another B. say good morning to workers C. make eye contact with clerks D. completely rely on machines 70. It can be inferred from the passage that the writer ________. A. is pleased with the modern pace of life B. feels more separated from others C. doesn’t want anyone to bother him D. sings high praises for communication technology
