The Body Temperature
The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer （温度计）when your are sick.
The body keeps the same temperature all the time ,because it balances the heat it produces and it gives off. It is always burning up food and , producing heat. It can produce heat faster when it needs to give off heat than when it becomes too warm. Let’s see how this happen.
The heat of your body is given off mainly through the skin. When you are cold, your skin is tight and shows “good flesh”. When you get chilly, you must dance around to keep warm or else you will shiver. Then your muscles begin to work, burn up fuel, and produce more heat. It is not pleasant to shiver, so you usually prefer to warm up by exercise, or put on more clothes to keep heat in.
When you are warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat ,and more body heat is used in evaporating the moisture（水蒸气） from your skin. You wear less clothing, too, in warm weather or warm room, so that warm can be given off freely. You feel less like exercising because your body is warm already, and the extra heat produced by exercise makes you uncomfortable.
You can see from the way you feel differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to play.

Passage Nineteen (TV’s Harmfulness)
Yes, but what did we use to do before there was television? How often we hear statements like this! Television hasn’t been with us all that long, but we are already beginning to forget what the world was like without it. Before we admitted the one-eyed monster into our homes, we never fond it difficult to occupy our spare time. We used to enjoy civilized pleasures. For instance, we used to have hobbies, we used to entertain our friends and be entertained by them, we used to go outside for our amusements to theatres, cinemas, restaurants and sporting events. We even used to read books and listen to music and broadcast talks occasionally. All that belongs to the past. Now all our free time is regulated by the goggle box. We rush home or gulp down our meals to be in time for this or that programme. We have even given up sitting at table and having a leisurely evening meal, exchanging the news of the day. A sandwich and a glass of beer will do – anything, providing it doesn’t interfere with the programme. The monster demands and obtains absolute silence and attention. If any member of the family dares to open his mouth during a programme, he is quickly silenced.
Whole generations are growing up addicted to the telly. Food is left uneaten, homework undone and sleep is lost. The telly is a universal pacifier. It is now standard practice for mother to keep the children quiet by putting them in the living-room and turning on the set. It doesn’t matter that the children will watch rubbishy commercials or spectacles of sadism and violence – so long as they are quiet.
There is a limit to the amount of creative talent available in the world. Every day, television consumes vast quantities of creative work. That is why most of the programmes are so bad: it is impossible to keep pace with the demand and maintain high standards as well. When millions watch the same programmes, the whole world becomes a village, and society is reduced to the conditions which obtain in preliterate communities. We become utterly dependent on the two most primitive media of communication: pictures and the spoken word.
Television encourages passive enjoyment. We become content with second-hand experiences. It is so easy to sit in our armchairs watching others working. Little by little, television cuts us off from the real world. We get so lazy, we choose to spend a fine day in semi-darkness, glued to our sets, rather than go out into the world itself. Television may be s splendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to real living when we spend a holiday by the sea or in the mountains, far away from civilization. In quiet, natural surroundings, we quickly discover how little we miss the hypnotic tyranny of King Telly.

Tess still stood hesitating like a swimmer about to make his dive, hardly knowing whether to return or move forward, when a figure came out from the dark door of the tent. It was a tall young man, smoking.
He had an almost black face, though red and smooth. His moustache was black with curled points, though he could not be more than twenty-three or-four. There was all unusual force in his face, and in his daring rolling eyes.
“Well, my beauty, what can I do for you?” said he, coming forward. And seeing that she was quite at a loss: “Never mind me, I am Mr. d’Urbervilles. Have you come to see me or my mother”
This differed greatly from what Tess had expected. She had dreamed of an aged and dignified face. She tried to keep calm and answered-“I came to see your mother, sir.”
“I am afraid you cannot see her-she is ill in bed,” replied the representative of the house; for this was Mr. Alec, the only son of the noble family. “What is the business you wish to see her about?”
“It isn’t business-it is-I can hardly say what.”
“Pleasure”
“Oh no. Why, sir, if I tell you, it will seem…”
Tess’s sense of a certain ridicule was now so strong that despite her general discomfort at being here, her rosy lips curved（弯曲）towards a smile, much to the attraction of the young man.
“It is so foolish,” she stammered（结结巴巴地说）; “I fear I can’t tell you”
“Never mind; I like foolish things. Try again, my dear,” said he kindly.
“Mother asked me to come,” Tess continued, “and, indeed, I was in the mind to do so myself.  But I did not think it would be like this. I came, sir, to tell you that we are of the same family as you.”
“Ho! Poor relations!”
“Yes.”
“Stokes”
“No; d’Urbervilles.”
“Ay, ay; I mean d’Urbervilles.”
“Our names are worn away to Durbeyfield; but we have several proofs that we are d’Urbervilles. The local scholars hold the view that we are, …and…and we have an old seal（印章）and a silver spoon marked with the same castle as yours. So mother said we ought to make ourselves known to you, as we’ve lost our horse by a bad accident; we can hardly make a living.”
“Very kind of your mother, I’m sure.” Alec looked at Tess as he spoke, in a way that made her uneasy. ”And so, my pretty girl, you’ve come on a friendly visit to us, as relations.”
“I suppose I have,” looking less confident and uncomfortable again.
“Well—there’s no harm in it. Where do you live? What are you?”
—Tess of the d’Urbervilles By Thomas Hardy

A professor I have worked pretty closely with has been diagnosed with Stage 4 cancer.It has been devastating for his family and heartbreaking for his students.

What made him extraordinary was not only that he was a rising star.He had only recently collected the highest honors for young researchers at the White House.We truly admired him—as someone put it, “He always has a smile and a kind word for everyone.” It is very hard to find someone who is extremely intelligent should be so nice a human being.

I decided that we needed him to know our_attitude and also how we are all praying for his recovery.I bought him a simple card which read, “Healing thoughts and wishes coming your way.” I met all the students he worked closely with and got them to sign on it.Each student in his laboratory signed and also added a message.“We love you so much”， “We miss you！We need you back here—get well soon”， “Please come back”， “Thank you for being such an inspiring teacher”， “I hope you recover soon”．..These were some of the messages that were written.Most of the students were really glad we were doing this and said it was a very good idea to give it to him.

He is still undergoing(经历) intense treatment，and along with his family is trying his best to stay optimistic and hopeful.I didn’t see a trace of self?pity or sadness when I met him last week.Instead，he paid attention to every word of my presentation and asked me several questions related to my work.I was amazed at how much he gave his 100% on that day in spite of being in pain because of chemotherapy(化疗)．He did not know if he even had another month to live.“I am trying to focus on staying positive，hoping to be back this summer，”he said.

Needless to say，I saw an expression of joy and hope on his face as he opened the card.He said he was truly touched to see the messages from the students he worked closely with.

There is one thing I learnt from last week：It is so important to tell people how much they mean to us and what an inspiration they are before it becomes too late.My professor，in spite of being too sick to teach classes，has managed to continue being a great teacher，introducing his last valuable message to us.

Once an Arab was traveling in the desert. When the sun went down in the west, he stopped and _36_ his tent then, made a fire and have a _37_ meal. When night fell, he_38_ down to sleep.
He had_39_ fallen asleep when he felt a soft _40_ on his elbow(手肘). He woke up to find that his camel had put his head inside the tent. The camel said: “Would you please let me keep my head in the tent to get warm? It is so cold outside. I will not take up too much  41  .”
The Arab was a  42  man, “All right, do as you  43  .” he said. Then he turned on his _44_  and went back to sleep.
It wasn’t long  45  he felt a push on his shoulder. It was the camel again. “Dear master,” the camel said, “my head is quite warm now, but my neck is still cold. Do you mind  46  I keep it inside the tent, too?”
“ _47_ .” the man said. But this time he felt a bit  48  , as camel had such a long neck.
No sooner had he shut his eyes  49  he got a harder push in his side. This time the camel said, “will you please allow me to bring my front legs inside and warm then a little?”
The Arab_ 50_ over to one side of the tent. He made _51_ as small as he could. It was not _52_ comfortable, and sleep was now out of  53  .Soon after that the camel gave his a rough push and said, “The tent is too small for the two of us.  54  , my two hind legs are still left in the cold. It is only_55_ that you should leave the tent wholly to me.” And with that, the camel kicked the poor man out.
