Passage Under certain circumstances there are few hours in life more agreeable than the h

our dedicated to the ceremony known as afternoon tea. There are circumstances in which, whether you partake of the tea or not—some people of course never do—the situation is in itself delightful. Those that I have in mind in beginning to unfold this simple history offered an admirable setting to an innocent pastime. The implements of the little feast had been disposed upon the lawn of an old English country-house, in what I should call the perfect middle of a splendid summer afternoon. Part of the afternoon had waned, but much of it was left, and what was left was of the finest and rarest quality. Real dusk would not arrive for many hours; but the flood of summer light had begun to ebb, the air had grown mellow, the shadows were long upon the smooth, dense turf. They lengthened slowly, however, and the scene expressed that sense of leisure still to come which is perhaps the chief source of one s enjoyment of such a scene at such an hour. From five o clock to eight is on certain occasions a little eternity; but en such an occasion as this the interval could be only an eternity of pleasure. Questions:

From which novel is this paragraph taken from？

Acclimatization, also physiological adaptation, is the process by which an organism becomes better adapted to 1 in an environment different from the one to which it was indigenous. If the environmental difference is extreme, changes take place in the 2 and physiology of the organism. Each organism, however, has certain limits of temperature and other conditions within which it can survive, and some alleged instances of acclimatizing have merely been 3 of unsuspected hardiness in the organism.

Humans, for example, can acclimate to extreme conditions through changes in normal physiological 4 . Persons who move from a temperate to a hot, dry climate 5 , changes in heart rate and body temperature such that in time they perspire less, and their perspiration 6 less salt. Although at an altitude of 7, 600 m most persons need to. breathe high-pressure oxygen for survival, through 7 acclimatization they may become able to breathe unaided. This is due to an increase in the number of red blood cells, which contain oxygen-carrying hemoglobin. The increase is 8 by the hormone erythropoietin, secreted by the kidneys. In addition a change in chemical composition within the red blood cells promotes migration of hemoglobin into the body tissues, where oxygen is needed.

The human organism also exhibits a 9 to the absence of natural light. As with most life forms, humans normally function in what is called a circadian rhythm corresponding to the length of the day. Humans who have lived underground under 10 conditions continue to show cyclical changes in physiology, demonstrating the existence of a natural biological clock. The period dictated by this internal clock, however is slightly longer than one day.

Owls and Larks（猫头鹰与云雀）

1. In this article, we lookat the importance of sleep for learning. Most healthy adults need eight of morehours of sleep. But why do we need sleep in the first place？ We need sleep forthe brain to get a chance to rebuild memories stored during the day andassociate these with previously learned things. If this process is interruptedby, say. the sound of an alarm clock, it may not be as effective. So if yoursleep is cut short by the alarm clock, how damaging is it？ The truth is thatit&39;s difficult to predict, as so much depends on how much sleep your bodyactually needs on that particular occasion.

2. The popular belief thatpeople are naturally either larks (early risers) or owls is false. The rea- sonwhy people tend to be one or the other has more to do with lifestyle, age, andpersonality. Many people who appear to be early birds may have just become sothrough habit, for example, parents with very young children. Teenagers can havedifficulty falling asleep until late at night and then they natu-rally haveproblems getting up the following morning.

3. The main reason why owlsare owls is that they tend to spend their time over a book, movie, or com-puter game till the early hours of the morning. They enjoy the quiet of thenight when they can pursue their passion. On the other hand, larks can makebetter use of early morning hours where they can study in quiet atthe time whentheir brains are most refreshed. So which is better for learning an owl&39;s or alark&39;s lifestyle？ The simple truth is that it is more complex than simply beingone or the other. Leading a well-balanced life in terms of work and play andsleeping enough to bring maximum&39; refreshment is probably th~ secret.

4. As for naps,experts oninsomnia (失眠) argue against taking naps, as these may keep people up at night. If yournap lasts only five minutes to half an hour and does not affect your ability tofall asleep in the night, it will probably help you be more alert in eveninghours. However, if you are hav- ing problems getting to sleep at night, it&39;snot only naps that you should avoid. Try not to drink a lot of alcohol, take nicotine(尼古丁) ,do mentally intense activities like preparingfor exams or doing ex- ercise in the evening. Some people swear that drinkingcoffee never stops them from sleeping like a log,whereas others will never gonear the stuff for fear of being awake all night. However, the best advice formost is to.avoid it in the evening, and if you drink coffee before a nap,remember you are likely to awaken as soon as the caffeine starts kicking in.

根据下列文章,请回答 21～25 题。 Text 1 However important we may regard school life to be

根据下列文章,请回答 21～25 题。

Text 1

However important we may regard school life to be, there is no denying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and obstruct curricular objectives.

Administrators have been aware of the need to keep parents informed of the newer method used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript. writing, and developmental mathematics.

Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The many interviews carried on during the year as well as new ways of reporting pupils' progress, can significantly aid in achieving a harmonious interplay between school and home.

To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent convert his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip, and engaging in scores of other activities that have a mathematical basis.

If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics and, at the same time, enjoying the work.

Too often, however, teachers' conferences with parents are devoted to petty accounts of children' s offences, complaints about laziness and poor work habits, and suggestions for penalties and rewards at home.

What is needed is a more creative approach in which the teacher, as a professional adviser,plants ideas in parents' minds for the best utilization of the many hours that the child spends out of the classroom.

In this way, the school and the home join forces in stimulating the fullest development of youngsters' capacities.
