Earth Day was founded in 1970 as a day of education about environmental issues, and Earth Day 2020 occurs on Wednesday, April 22—the holiday’s 50th anniversary. The holiday is now a global celebration that’s sometimes extended into Earth Week, a full seven days of events focused on green living.

By the early 1960s, Americans were becoming aware of the effects of pollution on the environment. Rachael Carson’s 1962 bestseller Silent Spring pointed out the dangerous effects of pesticides(杀虫剂) on the American countryside. Later in the decade, a 1969 fire on Cleveland’s Cuyahoga River shed light on the problem of chemical waste disposal. Until that time, protecting the planet’s natural resources was not part of the national political plan. Only a small portion of the American population was familiar with environmental issues—let alone practiced-recycling.

Elected to the U.S. Senate in 1962, Senator(参议员) Gaylord Nelson was determined to convince the federal government that the planet was at risk. In the fall of 1969, Nelson, considered one of the leaders of the modern environmental movement, announced the Earth Day concept at a conference in Seattle and invited the entire nation to get involved. He later recalled: “The response was electric. Telegrams, letters and telephone inquiries poured in from all across the country. The American people finally had an opportunity to express their concern about what was happening to the land, rivers, lakes and air.”

The first Earth Day was effective at raising awareness about environmental issues and changing public attitudes. According to the Environmental Protection Agency(EPA), “Public opinions polls(投票) indicate that in May 1971, 25 percent of the U.S. public declared protecting the environment to be an important goal, a 2,500 percent increase over 1969.”

Earth Day kicked off the “environmental decade with a bang,” as Senator Nelson later put it. During the 1970s, a number of important environmental laws were passed, among them the Clean Air Act, the Water Quality Improvement Act and the Endangered Species Act, etc. Another key development was the establishment of the EPA in December 1970, which was tasked with protecting human health and safeguarding the natural environment—air, water and land.

A.The overuse of pesticides had little impact on the American countryside.

B.The fire on Cuyahoga River was caused by improper chemical waste disposal.

3.The EPA was set up to_______.

高三英语阅读理解中等难度题查看答案及解析

As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients (原料) that go into baking a loaf of fresh bread.

Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don' t become bilingual (双语的) by learning lists of vocabulary. You don' t become a speaker of a language by memorizing grammatical rules. You become bilingual by entering a community that uses that other language as its basic means of communication.

I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast (酵母), salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough (面团).

In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, “Have you already been eaten?” when you meant to say, ‘‘Have you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread.

Remember the old saying, “If you can’ t stand the heat, get out of the kitchen". This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In other words, we can' t stand the heat, so we get out of the kitchen.

However, the language learner who stays in the kitchen—in the heat—until the combined

ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He is glad that he did not "get out of the kitchen” at the important moment when the oven seemed too hot.

Now the baker enjoys good bread, seated at the table with family members and guests. However, he does not focus on "bread" but rather on enjoying the whole feast: fine salads, pastas, fresh vegetables, rich desserts and so on. And the language learner has arrived when he no longer needs to focus on language. Language merely becomes one element in the "feast" of membership in his chosen community.
