Your heart is located in your chest, a little to your left. This heart of yours, which is about the size of your two fists held together, beats about 90 times a minute. A grown person's heart beats about 60 to 80 times a minute. The heartbeat is not just the same in all persons, and it is not the same in any one person at all times.

When your heart beats, it is pumping blood to all parts of your body. If you could examine your heart closely, you would see that it is really two pumps placed side by side, and working at the same time. Each pump has two parts, the upper part called the auricle (心房), and the lower part called the ventricle (心室). The auricles receive the blood as it comes into them after it has been pumped through the body. The ventricles pump the blood out. The right one pumps the blood to the lungs and the left one pumps the blood to all other parts of the body. At the top and bottom openings of each ventricle are valves (阀门) which make the blood go in only one direction.

Your heart is sometimes called the engine or the motor in your body and sometimes called the pump. It works away, both day and night. First it pumps out some blood, rests for a few seconds, and then it pumps some more. In a normal day, the heart pumps about 2,500 gallons of blood from the auricles and ventricles.

By using a stethoscope to listen to the heart, the doctor can tell whether your heart is beating evenly and whether the valves are closing tightly. The stethoscope makes these sounds so clear that the doctor can hear them easily. The stethoscope has an earpiece that he places on your chest and tubes that he places in his ear. The earpiece carries the sound or your heart's beating along the tubes to the doctor's ears, and it makes the sound seem much louder than it really is. The doctor could listen to your heartbeat by pulling his ear against your chest.

An easy experiment can help you understand what happens when the heart beats. You can do this experiment with a hollow rubber ball. Make a small hole in it, and fill the ball with water through the hole. When you squeeze the ball, you will notice how the water comes out in a spurt each time you squeeze. After each spurt the ball comes back to its round shape again. Something like this happens when your heart beats. The muscles in your heart grow smaller, or contract, and squeeze the blood out of the heart. Each time this happens, we say your heart is beating. Perhaps you have noticed that the doctor places his finger on the pulse in your wrist when you are ill. By doing this he can tell how fast your heart is beating.

If you ask people to name the one person who had the greatest effect on the English language, you will get answers like “Shakespeare,” “Samuel Johnson,” and “Webster,” but none of these men had any effect at all compared to a man who didn’t even speak English-William the Conqueror.
Before 1066, in the land we now call Great Britain lived peoples belonging to two major language groups. In the west central region lived the Welsh, who spoke a Celtic language, and in the north lived the Scots, whose language, though not the same as Welsh, was also Celtic. In the rest of the country lived the Saxons, actually a mixture of Anglos, Saxons, and other Germanic and Nordic peoples, who spoke what we now call Anglo-Saxon (or Old English), a Germanic language. If this state of affairs had lasted, English today would be close to German.
But this state of affairs did not last. In l066 the Normans led by William defeated the Saxons and began their rule over England. For about a century, French became the official language of Eng-land while Old English became the language of peasants. As a result, English words of Politics and the law come from French rather than German. In some cases, modern English even shows a distinction (区别) between upper-class French and lower-class Anglo-Saxon in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.
When Americans visit Europe for the first time, they usually find Germany more "foreign" than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition.
