LED lighting products produce light up to 90% more efficiently than incandescent light bulbs（白炽灯）.  LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs（白炽灯）.  A carbon footprint is the amount of greenhouse gases - mainly carbon dioxide - released into the air by a particular human activity. For example, when you drive a car, the engine burns fuel which creates a certain amount of greenhouse gases. When you heat your house with coal or electricity, you also generate greenhouse gases. Even the production of food and goods emits some quantities of greenhouse gases. Together these emissions make up a carbon footprint. water conservation renewable energy carbon footprint reusable water bottle greenhouse effect LED bulb Complete the brochure with the expressions. reusable water bottle carbon footprint renewable energy LED bulb Water conservation greenhouse effect Environmental problems to be solved Environmental problems to be solved A lecture about smog A lecture about smog → air pollution in cities → in the 1900s → a lot of coal was burned and no wind → chemicals coming from traffic and factories → people pay to drive in the center → people pay to drive in the center 1900s The Great Smog no wind chemicals coming from traffic chemicals requirements of paying to drive How many times was the speaker interrupted?

(2022年全国甲卷)你校将以六月八日世界海洋日为主题，举办英语征文比赛。请你写一篇短文投稿，内容包括： 1、海洋的重要性；2、保护海洋的倡议 注意：1、词数100左右；2、短文的题目和首句已为你写好。 Our Oceans, Our Responsibility June 8th was officially named by the UN in 2009 as World Oceans Day. It was set up to raise the awareness of protecting the oceans, which plays a crucial part in the global ecosystem. Ocean, home to countless sea creatures for millions of years,has an uncertain future.How  many of us are aware that over 1 million animals are killed by ocean pollution each year and the ice caps are more than 50% thinner than they were 40 years ago.If we do not change our ways, some day in the future,all of these things will be gone.And we will be gone,too.It’s up to us to decide together what happens next.As high school students,priority is given to the ordinary thing.The less energy you use, the less carbon dioxide is released. Replacing a regular light bulb with a(n) LED bulb is a great start.Plus,water conservation is important because clean water is a limited resource. Also, we use a lot of energy to process clean water. Ocean protection is now part of daily life.But it’s worth checking common ideas and opinions to protect the ocean. Thank you null 148774.05 146684.05 $$
