1 . Do Dogs Dream?
Unlike cartoon images (图像、影像), real dogs don’t speak and describe their sleep. So you may wonder: do dogs dream like their owners?
A scientific research conducted at MIT found that during sleep, brains of humans and dogs work in a similar manner. When you or your dog first falls asleep, you experience SWS—slow wave(波) sleep—when the brain waves are slow but muscles (肌肉) are still active. Later a deeper stage of sleep happens. This stage is called REM sleep — rapid eye movements sleep. During REM, muscles are more relaxed, but the mind is more active. It was proved that both humans and dogs experience these two stages of the sleep circle. Since we know that humans dream, it is safe to conclude(做出结论) that dogs dream too.
Scientists found that as a dog falls asleep, his breathing becomes deeper and more regular(规则的). After about 20 minutes in REM sleep, dreams usually begin for normal dogs. While dreaming, the dog’s breathing may become weak and irregular, and his eyes move about behind the closed lids (眼睑) as if the dog is looking at something. By comparing brain wave patterns, researchers suggested that during REM, dogs are visualizing (呈现) dream images much like humans do during this stage of sleep.
Besides, it also found that during REM, the sleeping brain operates much like it does when awake, so both man and dogs dream about things that happen during their waking hours. Information gathered during the day is processed at night and may be relived in dreams. So your dog may “sleep run” as he runs after a cat or fetches a ball.
Studies also show that some dogs dream more than others, and the frequency and length of dreams are different according to the age and size of dogs. Young puppies usually experience more dreams than adult dogs. One possible reason is that puppies get huge amounts (数量) of new information daily and have much to process at night. Among dogs of the same age, smaller dogs seem to have more dreams than their bigger friends, but their dreams may last shorter. Dream length and frequency are also related to the amount of sleep required. A dog that has an active day outside may sleep more soundly than usual and experience longer periods of REM sleep, giving him more time to dream.

2 . American people like to say “Thank you” when others help them or say something kind to them. People in many countries do so, too. It is a very good habit.
You should say “Thank you” when someone passes you the salt on the table, when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is very beautiful. “Thank you” is used not only between friends, but also between parents and children, brothers and sisters.
“Excuse me” is another short sentence they use. When you hear someone say so behind you, you know that someone wants to walk past you without touching you. It's not polite to break others when they are talking. If you want to speak to one of them, say “Excuse me” first, and then begin talking. You should also do so when you begin to cough or make any noise before others.

5 . April 22 is Earth Day. Everyone on the earth should care about and protect the earth!
The earth has warmed by about 1°F (华氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.
First, the greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.
People can affect the earth’s air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

6 . Healthy eating doesn't just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others' healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty--sometimes you are just thirsty, and you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. Because you don't eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast
Eat healthy snacks like fruits, yogurt(酸奶) or cheese. We all need snacks sometimes. In fact, it's a good idea to eat two healthy snacks between your three meals. This doesn't mean that you can eat a bag of chips instead of a meal.
Don't eat dinner late. In our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8-10 hours.
