Earth Day 【小题1】 (found) in 1970 as a day for education about environmental problems, and Earth Day 2020 occurs on Wednesday, April 22- the holiday's 50 anniversary. The holiday is now a global celebration that's sometimes extended into Earth Week, a full seven days of 【小题2】 (event) focused on green living.

【小题3】 (elect) to the U. S. Senate (参议院) in 1962, Senator Gaylord Nelson was determined to convince the federal government that the planet was 【小题4】 risk In 1969, Nelson developed the idea for Earth Day after 【小题5】 (inspire) by the anti-Vietnam War “teach - ins” that were taking place on college campuses around the United States.

Denis Hayes, a young activist 【小题6】had served as student president at Stanford University, was selected as Earth Day's national coordinator (协调者), and he worked with 【小题7】 army of student volunteers and several staff members from Nelson's Senate office 【小题8】 (organize) the project

The first Earth Day was effective at raising 【小题9】   (aware) about environmental problems and transforming public attitudes. Earth Day kicked of the “Environmental decade with a bang.” as Senator Nelson later put it. The theme of Earth Day 2020 is “climate action”. Earth Day Org. hopes it will be the 【小题10】   (large) volunteer event in history.

Many of us were raised with the saying “Waste not, want not.” None of us, however, can【小题1】 (complete) avoid waste in our lives.

Any kind of waste is thoughtless. Whether we waste our potential talents, our own time, our limited 【小题2】 (nature) resources, our money, 【小题3】 other people’s time, each of us should become more aware and careful. A small good habit can make a big【小题4】 (differ). It’s a good feeling to know in our heart we are doing our best in a world 【小题5】 is in trouble. By being devoted to 【小题6】 (save) oil, water, paper, food, and clothing, we are playing 【小题7】 part in cutting down on waste.

We must keep reminding ourselves that it is easier 【小题8】 (get) into something than to get out of it. Actually, severe damage【小题9】 (do) to our land is fairly recent in the history of our evolution. It’s time for us to say no to waste so that our future generations【小题10】 (be) able to develop well. We can’t solve all the waste problems, but we can encourage mindfulness.

Pollution takes away all the beauty of the beaches of Hawaii. I hate to go to the beaches on 【小题1】 (sun) weekends and see rubbish bags【小题2】 (lie) on the sand, cigarette butts (烟头) 【小题3】(bury) in the sand, and soda cans floating in the ocean.

One thing that really annoys me is 【小题4】 I see tourists who visit Hawaii leave their rubbish on the beaches. I was always taught after drinking soda to throw the can into the place 【小题5】 it should stay — the trash can. Another thing that annoys me is that some people walk right by rubbish 【小题6】 pretend that it’s not there.

The dogs or the fish are not to blame for it. It’s our fault and we must blame 【小题7】(we). Everyone has to do his or her part 【小题8】 (solve) this problem. It can’t be difficult to do the job. There are a lot of things that we can do. First of all,we can help pick up rubbish along the beaches. We could also form organisations that help clean up our beaches. More 【小题9】 (important), we need to start now before the beaches 【小题10】 (damage) beyond repair.
