Our planet is heating up because of the greenhouse effect. This is one of the reasons why the earth is seeing more extreme(极端的) weather events. \underline{\quad1\quad} But what's the greenhouse effect on earth, and what can we do to reduce it?
Let's first think about a greenhouse—you may have one in your garden! It's a glass building that protects plants against low temperatures by trapping(吸收) heat inside. But, while this helps your plants grow, the earth is trapping heat in the same way, and it's causing global warming. When oil and gas are burnt for power, $\ce{CO_{2}}$ is sent out as a waste product. It enters the atmosphere(大气层) and acts like a blanket(毯子) around the planet. \underline{\quad2\quad}
The influence of gases on the earth's climate was first examined in the 1820s. Eunice Foote, a scientist, tested the effects of sunlight on different gases. \underline{\quad3\quad} And then the idea of the greenhouse effect was born.
\underline{\quad4\quad} The UN recommends using more energy-saving electrical equipment at home. Also, if you wash your clothes at $30°\mathrm{C}$ instead of a higher temperature, less electricity is used. A change in diet is also something to consider; plant-based foods, compared to meat, need less land and water to be produced.
We only have one planet. \underline{\quad5\quad} Though the universe is big and there are a large number of planets there, so far we haven't found another one that is suitable to support life. Even if we find one in the future, people present can't wait until that day.
A. Let's try and take care of it.
B. A greener lifestyle helps save energy.
C. They include heatwaves, forest fires, floods, etc.
D. We can do something to reduce the greenhouse effect.
E. She discovered that $\ce{CO_{2}}$ traps heat more than other gases.
F. As a result, heat can't run away and the temperature increases.
1. ______ 2. ______ 3. ______
4. ______ 5. ______
