There is an old saying in English: "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.
Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which tolerated the pain for the longest time was 'the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins (內(nèi)啡肽) in the brain. These are natural chemicals which diminish both stress and pain.
There is also some evidence to suggest that laughter helps the body's immune(免疫的)system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group served as the control group - in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists (精神病學(xué)家) in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.
In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are strictly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers.This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.
What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of skill, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their insistence to the present that is amazing. In Egypt, the US, China,Japan and among the Arctic peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys reflect their surroundings.Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.
Because toys can be generally regarded as a kind of art form, they have not been affected by technological quick development that characterize inventions for adult use. The progress from the wheel to the ox-cart to the automobile is a direct line of ahievement. The progress from a rattle(撥浪鼓) used by a baby in 3000 BC to one used by a baby today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of times and subject to the limtations of available materials.
【小題1】. The reason why the toys most boys play with are different from those that girls play with is that_________.

A.their social roles are strictly determined
B.most boys would like to follow their fathers’ professions
C.boys like to play with their fathers while girls with their mothers
D.they like challenging activities
【小題2】. Which of the following is the author’s view on the historical development of toys?
A.The making skills in toys has remained essentially unchanged.
B.Toys have remained basically the same all through the centuries.
C.The toy industry has witnessed great improvement in technology in recent years.
D.Toys are playing an increasingly important role in shaping a child’s character.
【小題3】. Regarded as a kind of art form, toys________.
A.follow a direct line of achievement
B.a(chǎn)lso appeal greatly to adults
C.a(chǎn)re not characterized by technological progress
D.reflect the pace of social progress
【小題4】. The author uses the example of a rattle to show that________.
A.in toy-making there is a continuity in the use of materials
B.even the simplest toys can reflect the progress of technology
C.it often takes a long time to introduce new technology into toy-making
D.even a simple toy can mirror the artistic tastes of the time

Most British telephone cards are just plain green, but card collecting is becoming a popular hobby in Britain and collectors even have their own magazine, International Telephone Cards. One reason for their interest is that cards from around the world come in a wide variety of different and often very attractive designs. There are 100, 000 different cards in Japan alone, and there you can put your own design onto a blank card simply by using a photograph or a business card.
  The first telephone cards, produced in 1976, were Italian. Five years later the first British card appeared, and now you can buy cards in more than a hundred countries. People usually start collecting cards because they are attractive, small and light , and they do not need much space. It is also a cheap hobby for beginners, although for some people it becomes a serious business. In Paris, for example, there is a market where you can buy only telephone cards, and some French cards cost up to 4, 000 pounds. The first Japanese card has a value of about 28, 000 pounds. Most people only see cards with prices like these in their collectors magazine.

科目:高中英語 來源:2012屆廣東省廣州市禺山高級(jí)中學(xué)高三第一次月考英語試卷 題型:閱讀理解

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized(把…歸類) as "honor" help you create this life of good feelings.
Here's an example to show how honorable actions create happiness.
Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky(卑鄙的) excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness?
In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate(演示) that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased.  Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility(高尚).
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.
【小題1】According to the passage, the positive action in the example contributes to our_______.

A.self-respect B.financial rewardsC.a(chǎn)dvertising abilityD.friendly relationship
【小題2】The author thinks that keeping silent about the uncharged item is equal to_______.
A.lyingB.stealingC.cheatingD.a(chǎn)dvertising
【小題3】The underlined phrase "bringing the error to the clerk's attention" means_______.
A.telling the truth to the clerkB.offering advice to the clerk
C.a(chǎn)sking the clerk to be more attentiveD.reminding the clerk of the charged item
【小題4】How will we feel if we let the clerk know her mistake?
A.We'll be very excited.B.We'll feel unfortunate.
C.We'll have a sense of honor.D.We'll feel sorry for the clerk.
【小題5】Which of the following can be the best title of this passage?
A.How to Live TruthfullyB.Importance of Peacefulness
C.Ways of Gaining Self-respectD.Happiness through Honorable Actions

科目:高中英語 來源:2012屆安徽省安慶一中高三第三次模擬考試英語試卷(帶解析) 題型:閱讀理解

A farm planted levels or floors is called a vertical(垂直的)farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards,rather than outwards,it requires much less space than a conventional farm.
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18­story vertical farm could feed as many as 50,000 people,all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time,food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(殺蟲劑) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space,therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course,not all food does well with this type of planting,but there are many crops that actually seem to do better.
In some climates,a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words,we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now,but they are a concept that will solve many of our problems in the future.
【小題1】According to the passage, a vertical farm________.

A.is mainly built outwards
B.is dependent on solar power
C.is planted on levels upwards
D.is only an environmental friendly farm
【小題2】Compared to the conventional farm, the vertical farm can________.
A.depend far less on sunlight
B.greatly increase the use of soil
C.help to protect the limited gardens
D.reduce the use of harmful pesticides
【小題3】It can be learned from the passage that vertical farms________.
A.have been put into use
B.only use hydroponics to grow food
C.need less room than conventional farms
D.may increase the transportation costs
【小題4】What would be the best title for the passage?
A.Vertical farms for our future
B.Ways to deal with future problems
C.Vertical farms and green skyscrapers
D.Making Full Use of Our Limited Land
