“Dreams may be more important than sleep. We all need to dream” some scientists say. Dreams take up about one quarter of our sleeping time. People have several dreams each night.

    Dreams are like short films. They are usually in color. Some dreams are like old films. They come up over and over again. That may be the dreamer worrying about something. Dreaming may be a way of trying to find an answer.

    Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.

    Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is still at work when we dream. That is why we may have a long sleep and still tired after waking up.

    What are hurricanes?

    You may already know that hurricanes are storms. They can cause

terrible waves, winds, and rains. They happen during “Hurricane

Season,” which is from June 1st until November 30th in the Atlantic

Ocean and from May 15th until November 30th in the Pacific Ocean.

Kinds of Hurricanes

    There are five kinds of hurricanes. it helps people know a hurricane is so bad because the greater the wind speed is, the more dangerous the storm is. For example, a kind of hurricane has winds over 155 miles per hour, which are strong enough to break the buildings along the seaside completely.

    Hurricane Dangers

    When a hurricane happens together with heavy rain, there can be a terrible flood. The centre of a hurricane is called the eye. While most of a hurricane has dangerous strong winds, when the eye is a calm area in the storm in fact. When the eye of a hurricane passes over land, people might think that it's over, but before long the wind and rain increase again as the second part of the hurricane moves through.

    Hurricane Safety Tips

    There is no way to stop a hurricane or make it change direction, so if you ever find yourself in the path of a hurricane, be sure to remember the following safety tips.

    ● Be sure you have a radio, fresh drinking water, and enough food.

    ● Tell neighbors, friends, and family members your emergency plans. Tell them where you'll go if you need to leave your home.

    ● Stay inside during the storm. You could be badly hurt if you go outside.

    What's the first thing that you notice when you walk into your favorite restaurant? Is it the smell of fresh pizza, or the sight of your favorite desserts? Food that looks and smells good will probably taste good, but what about sound? Is that important, too?

    Scientists now believe that the taste of food can change when your ears hear different sounds, but it has to be right kind of sound. When you turn on a microwave with popcorn in it, it soon starts to pop. Do you think, "That sounds tasty!"?Not really, you probably think it's nearly ready. But when you smell it, you go to get the salt and the butter. Hearing the popcorn makes you think about it, but smelling it tells you that it tastes good. So what arc the sounds to change the tastes of the things?

    In an experiment(实验)in a fish restaurant, customers(顾客)listened to the sound of the seaside while they ate. Did it make a difference? Yes, it did Listening to the sea seemed to improve the taste of the food. It was fresher and saltier. When the restaurant tried the same experiment with the sound of the farm animals, there was no difference in taste. The results are going to be useful for restaurants. Perhaps they will try to use fewer unhealthy things, like salt and sugar in food With the right music or sounds, perhaps we won't taste the difference.

    Restaurants are also beginning to set a connection(联系)between food and the sound that the packet(包装袋)makes. Pick up a packet of your favorite potato chips, what does it sound like? One restaurant recently changed the material(材料)that they used to make their potato chip packets because experiments show that the packet which makes a right noise will make customers think the potato chips are fresher. Another idea is that a list of music will begin to appear on food packets, so if you don't like your green vegetables, the right music or sounds could help you learn to love them.

    Drinking water is good for your health. There are some scientific ways of drinking water.

    ⒈It is the best medicine to drink two glasses of water in the morning.

    ⒉Drink clean water.

    ⒊Drink the water that has not been boiled.

Many people think boiled water is safe and good for people's health. In fact, it is not true. The boiling point of water is 100 ℃. By boiling it, most bacteria(细菌) in water can be killed. In the past, the water was less polluted, so boiling was a good way to make clean water. But heavy metals and other dangerous things in today's water are much more terrible than bacteria. Boiling doesn't solve that problem. And boiling water may give us more dangerous things in our glass.

    ⒋Never use soft drinks to take the place of water.

    ⒌Water is also needed in winter.

    3) Drinking water at about 3 p. m. can clean the wastes out in your body.

    4) About eight o'clock in the evening is the best time to drink water. Your blood gets thicker when you sleep. Water will make your blood less thick.

    Besides, we should drink 2L of water every day. Water is so important in our life. We should drink water often.

    Are you a big fan of E. T. (Extraterrestrial) or aliens? Then you should read Extraterrestrial Civilizations (《地球以外的文明世界》) by American writer Isaac Asimov (1920~1992). In his 1979 book, Asimov looked at whether there is life beyond the Earth. He also talked about how we might be able to communicate with aliens someday. Asimov even told us that there are possibly about 500, 000 civilizations (文明) in the galaxy(银河系). The book may be a little out of fashion since it came out in the 1970s. But you'll still enjoy the good reasoning (推理 ) and imagination of it. Asimov was a science fiction(科幻故事) master. His most famous works talk about the relationship between robots and humankind.
