Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.

Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.

65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven liters（升） of water every day, but we needn’t drink this amount(量) because a lot comes from the food we have. If we don’t have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cool water!

1.When do we need more water?________

2.How much water are there in the human body?_________

3.Must most people drink five liters（升）of water every day?_______

4.Which of the following is not right?_________

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn’t breathing, you have four minutes before his brain is completely destroyed. Support his neck, tilt（使翘起）his head back and press his chin（下巴）upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn’t work, start mouth-to-mouth breathing. Press his nostrils（鼻孔）together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives.

To bring a child back to life, keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue grey color, you can feel no pulse（脉搏）,then pressing is the last chance of saving his life.

With arms straight, rock（摇动）forwards, pressing down on the lower half of the breastbone. Don’t be too hard or you may break a rib（肋骨）. Check how effective you are seeing if his color improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.

1.This passage is mainly about ________.

A. how to save people out of the water

B. how to give first aid to people who are drowning

C. how to do mouth-to-mouth breathing

D. how to save a child from a river

A. get him breathing again

B. take him to the nearest hospital as soon as possible

C. find someone to help you

D. call the First Aid Centre

3.In the last paragraph, the word “rescue” means ________.

A. breath            B.　 doctor        C.　 help            D.　 pulse

4.If the drowning boy has no pulse, ________.

A. pressing his chin upwards is enough to get him breathing again

B. blowing air into his mouth is sure to save his life

D. pressing his chest is the last chance of saving his life

5.Which of the following statements is true?

As the saying goes, “Without music, life would be a mistake.” Music is very important in our lives and here are four of the greatest musicians in history.

Ludwig van Beethoven(1770-1827)

Born in Bonn, Germany, Beethoven never held an official position in Vienna. He supported himself by giving concerts, teaching piano, and the sale of his compositions(作曲). The last 30 years of Beethoven’s life were filled with a lot of hard times, the first of which was his deafness. Beethoven’s music greatly influenced the next generation of musicians.

Johann Sebastian Bach(1685-1750)

Bach, “the father of modern music”, was born in Eisenach, Germany. His parents died when he was nine years old, and in 1695 he went to live with his brother Johann Christoph, who was an organist(风琴手) in Ohrdruf. He stayed there until 1700. Seven years later, he moved back to Weimar, where he served as court(宫廷) organist for nine years. His music greatly influenced classical music.

Frederic Chopin (1810-1849)

Chopin was born in Zelazowa Wola, Poland. He showed a talent for the piano at a very young age. Chopin began composing when he was still a child, but some of his early works have been lost. He gave his first public concert in 1818. Chopin was considered as the leading musician of his time.

Franz Schubert(1797-1828)

Schubert was born and died in Vienna. Unlike most of his predecessors(前辈),Schubert was not a great performer. He never had much money but he was very productive. He wrote his first masterpiece when he was only sixteen. However, he died young, before his talents had even been known.

1.Beethoven did Not make a living by ___.

A.teaching students B.doing business
