61. _____________
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.
62. _______________
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.
63. ________________
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.
64. _______________
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.
65. _______________
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.

【小题1】_____
Know to whom you’ll be speaking, and learn as much about your audience as you can. The more you can anticipate the kind of reaction your listeners will have to your speech, the more comfortable you’ll be in delivering your message. Be audience-centered rather than speaker-centered.
【小题2】_____
You will feel less nervous if you talk about something you are familiar with or have some personal experience of. Your comfort with the subject of the speech will be reflected in your delivery.
【小题3】_____
The better prepared you are, the less anxiety you will experience. Being prepared means that you have researched your topic and practiced your speech several times before you deliver it.
【小题4】_____
You are likely to feel the most anxious during the opening moments of your speech. Therefore, it is a good idea to have a clear plan for how you will start your speech. Being familiar with your introduction will help you feel more comfortable about the entire speech. If you know how you will end your speech, you will have a safe harbour in case you lose your place. If you need to end your speech ahead of time, a well-delivered conclusion can permit you to make a graceful exit.
【小题5】_____
One of the symptoms(症状) of nervousness is a change in your breathing and heart rates. Nervous speakers tend to take short, shallow breaths. To help break the anxiety—reduce breathing pattern, consider taking a few slow deep breaths before you rise to speak.

| A．How do we get the names for the days? B．The origin of division of the times. C．How did men invent the week? D．The Jews names the seven days. E．How did the Egyptians and the Romans name the days? F．Reason for no names of the days. |
Do you know how the days of the week get their names? There was a time in the early history of man when the days had no names! The reason was quite simple：men had not invented the week.
2. _____________
In those days, the only division of times was the month, and there were too many days in the month for each of them to have a separate name. But when men began to build cities, they wanted to have a special day on which to trade, a market day. Sometimes these market days were fixed at every tenth day, sometimes every seventh or every fifth day. The Babylonians decided that it should be every seventh day. On this day they didn't work, but met for trade and religious festivals.
3. _____________
The Jews followed their example, but kept every seventh day for religious purposes. In this way the week came into existence. It was the space between market days. The Jews gave each of the seven days a name, but it was really a number after the Sabbath day(which was Saturday). For example, Wednesday was called the fourth day (four days after Saturday)．
4. _____________
When the Egyptians adopted the sevenday week, they named the days after five planets, the sun, and the moon. The Romans used the Egyptian names of their days of the week: the day of the sun, of the moon, of the planet Mars(火星), of Mercury(水星), of Jupiter(木星), of Venus(金星), and of Saturn(土星)．
5. _____________
We get our names for the days not from the Romans but from the AngloSaxons, who called most of the days after their own gods, which were roughly the same as the gods of the Romans. The day of the sun became Sunnandaeg, or Sunday. The day of the moon was called Monandaeg, or Monday. The day of the Mars became the day of Tiw, who was their god of war. This became Tiwesday, or Tuesday. Instead of Mercury's name, that of the god Woden was given to Wednesday. The Roman day of Jupiter, the thunderer, became the day of the thunder god Thor, and this became Thursday. The next day was named for Frigg, the wife of their god Odin, and so we have Friday. The day of Saturn became Saeterndaeg, a translation from the Roman, the Saturday.

Gifts tighten personal relationships and provide a means of communication between loved ones. People say that a gift lets the recipient（接受者） know we are thinking of them, and that we want to make the person “feel special.” We want people to feel wanted, to feel part of our social or family group. We give presents to say “I’m sorry.” Sometimes it is difficult for us to find a present that someone will like. Sometimes we give things that we like or would frrl comfortable with. In all these cases, the gifts are sending out messages－often very expressive ones.

People tend to talk about presents in a fairly loving way.woman whose mother had died years ago described the many gifts around her house. These were gifts that her mother had given her over the years: “I appreciate these, and they mean something to me,” the woman said, “because I remember the occasions they were given on, and that they were from my mother, and the relationship we’ve had.” The gifts remain and keep the relationship alive in mind. This woman felt the same way about the gifts she gave to others. She hoped that the recipients would look at here gifts in years to come and

Emotions(情感)like these suggest that a positive spirit still lies behind gift giving. They prove that the anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful. Studies in Canada and elsewhere have also shown that this is not the case. Each gift is unique even if so many are given.The emotional benefit for those who exchange gifts is the very reason for the tradition to continue.
