Since the first Earth Day in 1970, Americans have got a lot “greener” toward the environment. “We didn’t know at that time that there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.

According to US government reports, emissions (排放) from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “green thinking” has become part of practices.

Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty-five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

1.According to Anderson, before 1970, Americans had little idea about _______.

A. the social movement B. recycling techniques

C. environmental problems D. the importance of Earth Day

2.Where does the support for environmental protection mainly come from?

A. The grass-roots level.

B. The business circle.

C. Government officials.

D. University professors.

3.What have Americans achieved in environmental protection?

A. They have cut car emissions to the lowest.

B. They have settled their environmental problems.

C. They have lowered their CO levels in forty cities.

D. They have reduced pollution through effective measures.

4.What is especially important for environmental protection according to the last paragraph?

A. Education. B. Planning.

C. Green living. D. CO reduction.

If you live in the U.S., you’re probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That’s because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That’s why the older your banana is, the flimsier(不结实的) it feels.

The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body’s ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

1.We can learn from the text that in the U.S. people ________.

A. like eating bananas

B. waste a lot of food every year

C. don’t make good use of banana peel

D. know little about the value of the flesh of bananas

2.What’s the role of ethylene in bananas?

A. Helping bananas grow faster.

B. Making banana peel stay strong.

C. Keeping banana flesh from going bad.

D. Helping to soften and sweeten banana peel.

3.Which of the following helps humans digest?

A. Vitamin C.B. Potassium.C. Vitamin B6.D. Fiber.

4.The last paragraph mainly shows that eating banana peel benefits our ________.

A. dietB. economyC. environmentD. physical health
