Effects of tourism

Nearly everybody likes traveling. Nowadays, tourism is becoming an indispensable industry in China. Moreover, our government has taken good measures to improve this new industry in recent years. For instance, many appealing scenic and historic spots have been explored. And therefore, thousands upon thousands of tourists around the world flood into China every year.

　 However, a coin has two sides. Advantages of tourism industry are always accompanied by disadvantages. Those who are in favour of tourism industry argue that our country can benefit a lot from it. On the one hand, we can introduce our splendid national culture to the world. On the other, we can increase our financial income. Additionally, tourism can help to promote the understanding and friendship among the peoples of the world.

The main reason why some people oppose tourism is that the masses cannot benefit from it, because too many tourists will lead to the higher prices of goods. Furthermore, it is also a danger to the environment, because too many tourists will bring more waste, which is difficult to deal with for the moment.

Anyway, as a rising industry, tourism has played its unique role in the development of China. China is a great country which is endowed with natural beauty and possesses historic relics. So for one thing, we should display our best to the world; and for another, we should take action to avoid any negative effects.

With the development of society and economy, animals and their habitats are getting pushed aside as households decrease in size and increase in number.

    Small numbers of people per household on average use more energy and goods per person. Greater numbers of households require more natural resources for construction. The possible result of this problem may be insufficient natural resources to meet consumer demand without endangering habitats important to biodiversity.

    Personal freedom and social choice may come at huge environmental cost. Direct costs include visible damage to animal habitats and plant life. Indirect costs include the release of more greenhouse gases.

    The effects of such “personal freedom and social choice” have already surfaced in south-west China’s Wolong Nature Reserve. In Wolong, they found that a reduced average household size was directly tied to an increase in homes, and thus an increase in the amount of firewood consumed for cooking and heating. The rise in wood fuel use has contributed to disappearance of forests and to the loss of habitats for giant pandas. 

    Curious about whether other parts of the world were experiencing similar phenomena, they got the support of a team of researchers including Stanford’s Paul Ehrlich, well-known for his population studies, to find out the household dynamics in 141 countries between 1985 and 2000. Their study proved that the difficult choice of Wolong is part of a global trend.

    In the 76 countries considered biodiversity “hotspots”, such as the United States, Brazil, Australia, and Kenya, the number of households grew by 3.1% every year, while the population increased just 1.8%. Meanwhile, the number of people per home dropped from 4.7 to 4.0. The decline in household size has resulted in 155 million additional households in hotspot countries, almost always limiting biodiversity.

    In the 10 non-hotspot countries — those without high-density areas of animal and plant species — similar results were found, though on a lesser scale. Even in countries experiencing population decline, such as New Zealand, the number of households still increased because of a reduction in household size.

1.What does the underlined word “insufficient” mean?

A. Plenty of.       B. Not enough.     C. Abundant.       D. Little.

2.It can be learned from the passage that China’s Wolong Nature Reserve__________.

A. is facing the same threat as many other parts of the world

B. sets a good example in protecting animals

C. is a place where giant pandas and their habitats are not affected

D. is a place where animals and their habitats are seriously damaged

3.Which of the following is best supported by the last two paragraphs?

A. Biodiversity is better kept in countries with smaller populations.

B. Biodiversity is better kept in hotspot countries.

C. The threat to nature from reduction in household size is a worldwide problem.

D. Both hotspot countries and non-hotspot countries face the threat of the same scale.

4.What does the passage mainly talk about?

A. Reduced household size leads to an increase in household number.

B. Modern homes consume more natural resources.

C. How to meet consumer demand without endangering animals and their habitats.

D. Reduction in household size as well as increase in household number threatens nature.

 

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?

To see whether babies know objects are solid. T. Bower designed a method for projecting an optical illusion(视觉影像)of a hanging ball. His plan was to first give babies a real ball, one they could be expected to show surprised in their faces and movements, All the 16 to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there.

Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land?

Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to re-appear. If the experiment took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The re-searcher substituted(替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week-old babies did not seem to notice the switch(更换).Thus,the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.

1.The passage is mainly about        .

A.babies’sense of sight                   B.effects of experiments on babies

C.babies’understanding of objects          D.different tests on babies’feelings

2..In Paragraph 3, “object permanence” means that when out of sight, and object           .

A.still exists        B.keeps its shape           C.still stays solid      D.is beyond reach

3..What did Bower use in his experiments?

A.A chair         B.A screen              C.A film            D.A box

4.. Which of the following statements is TRUE?

A.The babies didn’t have a sense of direction.

B.The older babies preferred toy trains to balls.

C. The younger babies liked looking for missing objects

D.The babies couldn’t tell a ball from its optical illusion.

 

For a long time, a boy wondered why his next-desk-pal was always the first in the class, whereas he could only rank the 21st. At home, he asked his mom, “Am I more stupid than other kids? How come I always lag behind? I just can’t come up with an answer.” Mom was aware that her son’s self-respect had been damaged by the ranking system, but she didn’t know what to say to help.

    She was tempted (想要) to say that intelligence differs and that yes, her son’s friend really was the smarter boy. But that would have so upset her son. Thank goodness she resisted the temptation to say it.

Her son and his friend went on to high school that year, but despite trying as hard as he could, her son’s friend still outdid him. But she was proud of her boy for his hard work, sincerely proud. It was around this time she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.

    Today her son no longer cares about rankings. He doesn’t have to, for he himself is now the top of the class – at the top national university he attends. Invited to speak to his old high school, he mentioned a valuable childhood experience: “Once, on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to me: ‘Do you see the seabirds fighting for food out there? When a wave comes near, the little birds rise quickly. The “clumsy” seagulls (海鸥) are far less agile (灵活的) and have to struggle to get away from the wave. But these “clumsy” birds prove to have the biggest, strongest wings, which open the widest and allow the bird to travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind. Son, I have a feeling that you are one of those seagulls.”

1. From the first paragraph, we could conclude the mother ______.

   A. knew her son was not bright enough

   B. saw the negative effects of the ranking system

   C. decided to help with her son’s school work

D. was troubled by her son’s low rankings

2.The mom was glad she didn’t give an answer at first because ______.

   A. she knew her son would forget his rankings soon

   B. she felt intelligence doesn’t mean everything

   C. she knew he was not strong enough for the truth

   D. she wanted to avoid another blow to her son’s self-respect

3.The story conveys the message that ______.

   a. only rankings show intelligence

   b. hard work and confidence can lead to a change in rankings

   c. parents should see children’s strengths and encourage them

   d. competition between students is good for society

   A. bc                B. cd               C. abc              D. bcd

4. Which of the following would be the best title for the story?

   A. How important are rankings?

   B. Little birds and seagulls

   C. The answer Mom gave

   D. Hard work pays off!

 

     Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

　　Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

　　These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

　　We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

1.What is the main idea of the first paragraph?

　　A.The air we breathe in is harmful.

B.Chemicals are released in the running water.

C.Chemicals are added to the drinking water.

　　D. The water in everyday use is unsafe.

2..In Paragraph 2, the underlined sentence means that .

　　A. homes and offices should be aired often

　　B. any pollution should be taken into consideration

　　C. bathing should be done with caution

　　D.we should prevent any pollution from doing harm to us

3.What is the purpose of the passage?

　　A.To call on us to guard our water.

　　B.To show us that no place is like home.

　　C.To make us aware of the pollution around us.

　　D.To argue that neither homes nor offices are safe.

 

The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed.” But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?

　　Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.

　　The study’s authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing older research showing that when people get feedback which they believe is very positive, they actually feel worse, not better. If you tell your stupid friend that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.

　　In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”

　　Those with low self-esteem didn’t feel better after the forced self-affirmation. In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think positive thoughts.

　　The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking.
