As global warming becomes more and more serious, each one of us must take action to help.
First, diet.
Changing what you eat could easily have a significant effect because animal agriculture creates about 14% of the world's greenhouse gas emissions (排放).
Second, travel.
Nearly all transport relies on fossil fuels. In the US, driving one mile in an average 2016 car emits 404 grams of CO2 equivalents per mile. But taking nearly any other means of transport will reduce CO2 emissions.
Third, energy.
Fourth, waste.
Think before you buy. The fashion industry creates about 10% of global greenhouse emissions and consumes more energy than flight and shipping combined.
Last but not least, plant a garden.
Plant a garden instead of building a yard out of cement (水泥), the production of which creates 8% of global CO2 emissions a year.
So from a burger to a cyclist, no one thing will have a big influence, but lots of little things can.

| C．Planting a garden helps reduce CO2 emissions and produce oxygen. |
| D．Each of us contributes a particular amount of CO2 into the atmosphere. |
| E．As we all know, the environment around us is getting worse and worse. |
| F．After walking, cycling is the best choice because it almost has no emissions. |

If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.
There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.
Keep up shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.

Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back, you’ll know you’re well on your way. Good luck!
