Laboratory work is your chance to learn science first-hand. It can be fun but you must be careful to prevent injury. Listen closely when your teacher reads and explains the rules before your first lab lesson.

LABORATORY RULES
Throughout the lesson	Do not enter the science lab without the teacher's permission. No food or drinks are to be allowed in the science lab.
Before the Experiment	Read all instructions carefully before every experiment. Prepare all apparatus (仪器) and arrange them so that you will not knock them over while doing the experiment.
During the Experiment	If you are unsure of how to use any apparatus or how to operate, ask your teacher for help. Never smell or taste chemicals unless your teacher gives permission.
After the Experiment	Wash all apparatus after use and return them to the places where they were. Throw waste materials in proper waste baskets.
First Aid	Report all accidents to your teacher immediately. If you spill (溅出) any chemicals onto your body of clothing, wash with plenty of water and report to your teacher.

       I wonder whether there is any girl or boy who does not like to see a rainbow in the sky. It is so beautiful.
       There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away.
       A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the effect of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow（弓).
    That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds.
    Every rainbow has many colours in the same order. The first or the top colour is always red, and the next comes orange, then yellow, and last of all, blue. A rainbow is indeed one of the wonders of nature.

    Because earthquakes happen without warning, it's important to take steps now to prepare.
    Because you don't know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
    A person needs at least 1 or 2 gallon of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
    It's always a practical idea to keep food that can be stored easily. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手电筒) and spare batteries.
    Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake. Maybe it's dangerous. Prepare a battery-powered radio and spare batteries. Most telephones will be out of service, so radios will be your best thing of information.
4. Clothes.
    If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.

Do you have brown hair? Are you taller than other kids your age? These characteristics were decided before you were born. You got your traits from your parents. They passed their traits on to you through genes (基因).

Genes carry codes (代码) for blue eyes or brown eyes. Genes say how tall you will get and what color hair you will have. You got half of your genes from your mother. You got half of your genes from your father. So you have your own set of genes. Each person gets different genes for each body part. That is why you look like but not exactly like your brother or sister.

A dominant (显性的) gene shows up most of the time. Brown eyes are dominant over bluc eyes. A recessive (降性的) gene shows up less often. Light hair comes from a recessive gene. Dark hair is more common. Look at the eye color and hair color of the people around you. You will see that this is true.

Genes help to make you who you are. But they don't tell the whole story. Your genes may help you to be fast and strong. But you still need to learn how to run or swim or skate well.

Thousands of years ago, people couldn't live for long. Most people only lived to be twenty-five or thirty years old. 20% of people died before they were twelvemonths old and another 30% could not live to be five years old.

Today, people can live much longer. One reason is that the water we drink is cleaner. Clean water does not cause diseases（疾病）. Besides, medical treatment is better today. More and more people live to be over eighty.

Women often live longer than men. For example, in Japan, women usually can live to be eighty-five, but men can only live to be eighty.

In the future, people will probably live longer than today. Here are many things we can do to help people live longer. For example, we can make sure that everyone has enough medicine to fight against diseases. Also, it is necessary for everyone to have enough to eat. Today many people die because they do not have enough food.

Last year, a special kind of glove came out. It was invented to help blind people to learn Braille, which is a special system for the blind to read by touching. Shaking motors (震动马达) are put on each finger of the glove. They can make different sounds to tell a user which letter he is touching. Recently, two British college students have invented another special glove for the blind. It can make the user feel small and quick movements. An ultrasonic sensor (超声波传感器) with a battery is put on the back of the glove. When the user wearing the glove is close to an object(物体), ultrasonic waves (超声波) from the glove are sent out (发出). As soon as they hit the object in front, the waves will return to the glove. Then the waves cause the glove to shake. And the ultrasonic sensor makes different kinds of sounds. The sounds make the user know how far he is from the object.

In the college invention competition, the two students got first prize and won 1,540 pounds. One of the designers said, "Now the ultrasonic sensor on the glove is quite large. We're going to use the money to develop a smaller and lighter ultrasonic sensor."
