There are many colors in nature. But do you think that a color has weight? Let's do a test.

First, put two objects with the {#blank#}1{#/blank#} weight into two boxes. Then cover the boxes. Third, wrap (包裹) one box with a red piece of paper, the other with white. Now hold the boxes {#blank#}2{#/blank#} your hand one by one. Which one is {#blank#}3{#/blank#} ? It is certain that you will think the red one is heavier. Why do you think so? A scientist did many {#blank#}4{#/blank#} and found that different colors have different weights in a man's mind.

Also, scientists say that people accept the colors they like, and {#blank#}5{#/blank#} the colors they hate. So your body and mind will be {#blank#}6{#/blank#} by using the colors you like. Or you'll be nervous {#blank#}7{#/blank#} even get ill. For example, you {#blank#}8{#/blank#} blue and hate red. If you stay in a room with red windows and wallpaper for two hours, you'll feel you have been there for {#blank#}9{#/blank#} hours. But if the room is blue, you'll feel you have been there for only an hour, And, if a person walks {#blank#}10{#/blank#} of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colors.

We know animals have emotions. They can feel fear. We also think they feel love, since they have strong relationships with each other. So are animal emotions s{#blank#}1{#/blank#} to our own? And do animals have a sense of humor?

A Parrot's Joke

Sally's parrot Bongo didn't get along with her o{#blank#}2{#/blank#} parrot, Paco. In fact, Bongo clearly didn't like Paco at all! One day, Sally cooked a chicken for dinner. She started to cut the chicken with a knife. 

"Oh, no! Paco!"Bongo said loudly and laughed. Sally laughed, too, and said, "That chicken is not Paco. ""Oh…no, "said Bongo. This time, she sounded d{#blank#}3{#/blank#}. Then the parrot laughed at her own joke.

Yoga Dog

Jean enjoys yoga and so does her dog Buffy. W{#blank#}4{#/blank#} Jean does yoga, Buffy carefully places her toys on Jean's body. If a toy falls, Buffy runs to put it b {#blank#}5{#/blank#}. Does this behavior have any real purpose?"She thinks it's funny!"says Jean. 

Animal Laughter

Can dogs "laugh"?Recent research shows that dogs can tell each other when they want to play. They make a special sound a kind of "laugh. "Psychologist (心理学家)Patricia recorded the sound. Then she played it to dogs and s{#blank#}6{#/blank#} their behavior. "All the dogs seemed to like the laugh, "says Patricia. So do animals have a sense of humor? If laughter is a clue, then p{#blank#}7{#/blank#} the answer is "yes!" .

Computers are useful machines. They can help people a lot in their life. For example, they can help people to save much time to do much work, and they can help people to work out many problems they can't do easily. Our country asks everyone to learn to use computers except the old people.

Today more and more families own computer. Parents buy computers for their children. They hope that computers can help them to improve their studies at school. But many of their children use computers to play games and watch videos. For most students, computers cannot help them to study better but make them fall behind. So computers are locked in boxes by parents.

In some other countries, even some scientists also hate computers. They say computers let millions of people lose their jobs or bring them a lot of trouble. Will computers really bring trouble to people or can they bring people happiness? It will be decided(被决定) by people themselves!

Cats or Dogs? Both cats and dogs are popular pets. Most families, however, can keep only one pet. It can be hard to decide whether to take a cat or a dog into your home. Here, some middle school students are having a cats VS. dogs debate（辩论）.

Group A：Donna Walker

We think cats are better for most families. Many people want to keep a pet, but they live a busy life. Cats don't have to be taken outside to use the bathroom. Instead, they just use a litter box. Their owners only need to keep the litter box clean. They don't need to worry if they are away at work for most of the day. They never have to run home from work early in order to walk their pet. 

Group B：Gary Hall

No, dogs are better. Just think about why you want to keep a pet. Dogs can bring you lots of happiness. When you go back home from school or work, your dog will always greet you at the door with excitement. Cats... huh... When you walk into the room, never expect your cat to be too excited about seeing you. What's the point in keeping such a pet？

Group A：Brian Ross

Well, cats seem to have their own timetables, but when they do look for love, they will do their best. Moreover, cats usually live longer than dogs. Most cats can live up to 15 years while most dogs only have 13 years on the planet. Isn't it nice to be able to spend more time with your pet?

Group B：Annie Miller

But dogs are more faithful. A dog never leaves its owner no matter what happens. Dogs also keep you safe. If a bad guy tries to break into your home, your dog will drive him away with loud barks. 

Group A：Paula Lee

Yeah, dogs make so much noise! Some dogs bark at almost every stranger, but are there so many bad guys? Cats, however, are quiet most of the time. 

Group B：Eric Bell

Dogs can be trained well. Cats have claws(爪子)and they are interested in everything. They can cause much more trouble!

How to learn English Well

Ladies and gentlemen, good afternoon! I'm more than glad to stand here and give you a short speech，

 Animals are our friends. Now a lot of people like to keep small animals as pets in their houses, such as cats, dogs. 

 People like to keep dogs best, next is the cats, and the last is the birds. Because these pets are very cute and friendly. Old people have these animals as their family members. They are like people's children. People give these pets nice names and buy nice food for them. They let them wear beautiful clothes too. People keep these pcts clean every day. They love them very much. 

 Children also like to keep these pets. They are like their friends, brothers and sisters. Children can play, sleep and take a walk with these pets. Sometimes when children are unhappy, pets are their best friends. They love them very much. 

 Pets are all very happy. They have houses and beds. They have much nice food to eat. They can walk with people in the park or go out to relax. 

 Do you think pets are important in our life? Would you like to keep a pet in your family?
