The Earth has warmed by about half a degree(0.50℃)over the last 100 years. It could be getting warmer on its own, but many scientists think that people are making the Earth warmer by making a greenhouse effect. The greenhouse effect is important. Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals.
Many of the things we do every day can change the Earth’s temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases.
Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water.
The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals.
Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don’t do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world.

Many people have a fear(害怕) of public speaking. According to a study, it has an influence on 3 in every 4 people. This fact is surprising and worrying, as most jobs require some speaking ability. The following will help you to make a speech better.
Write note cards. Write main ideas on your cards. Don’t write details. Put in some fun facts, questions, and other activities on the cards to share with the class. Don’t look at your note cards for a long time while speaking. If necessary, you’re only going to want to have a quick look at the card for information, not read every last word.
Smile at your class. When it comes time to speak, there’s nothing that draws your class into your speech than a good old-fashioned smile. Be happy, because you’re about to teach your class something they didn’t know before. Studies have shown that smiles are infections. That means once you smile, it’s hard for everyone else not to smile. So if you want your speech to go off well, smile. That’ll make everyone smile and maybe those smiles will make you actually smile.
Make eye contact. Nothing is more boring than listening to a speaker who looks at the floor or at note cards. Relax. Your class is made up of your friends and you talk to them all the time. Talk the same way now. have a look at every person in the classroom at least once. That way, everyone will feel like you’re communicating with them. Also, you’ll look like you know what you’re talking about.

Once when I was a teenager, my father and I were standing in line to buy tickets for the circus. Finally, there was only one family between the ticket office and us. This family made a big impression on me.
There were eight children, all probably under the age of 12. You could tell they didn’t have a lot of money. Their clothes were not expensive, but they were clean. The children talked excitedly about the clowns. It was clearly a very important day out for them. The father and mother seemed happy as they could be.
The tickets lady asked how many tickets the father wanted, he proudly answered, “Please let me buy eight children’s tickets and two adults’ tickets, so I can take my family to the circus.”
The ticket lady told him the price.
The man’s wife lowered her head. There was no longer a smile on the man’s face. He quietly asked, “How much did you say?”
The ticket lady again told him the price.
The man obviously didn’t have enough money. But how could he tell his kids the bad news?
Seeing what was happening, my dad took a $20 note from his pocket and dropped in on the ground. (We were not rich ourselves at all!) He then tapped the man on the shoulder and said, “Excuse me, sir, you dropped this.”
The man understood my father was helping him. He picked up the money, looked straight into my dad’s eyes, and in tears replied. “Thank you. This really means a lot to me and my family.”

Taking care of small children is one of the ways to make money. It is also called babysitting. Most parents do not have relatives living with them. They need someone to watch the children if they want to go out. A babysitter may play games, draw pictures, or read stories to the children, and then put them to bed at the proper time.
Mowing（割）lawns（草坪）for the neighbors is another common job. When people do not have time to mow their lawns in the garden, they are glad to pay somebody to do this.
Boys and girls can also help deliver newspapers in the neighborhood. They can walk or ride bicycles to deliver newspapers from house to house. They must do this every day if they want to make money in this way.
Some old people who live by themselves need help. Let them know if you like to help with the clean-up work, or go out to mail letters or buy things for them. They will perhaps pay you something each time or every week.
