Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country ； keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first-class roads, and other support facilities (配套设施）needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost. Which of the followings do you think has been discussed in the part before this selection?

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding （繁殖） rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical （等级的） societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”When a goby grows to within 5-10% of the size of its larger competitor, it .

Eddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada.
It all started when Graham Broad, a professor at the University of Western Ontario, found McKay’s name in a footnote in a book about university history. McKay was included in a list of university alumni （校友） who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives （档案馆） in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad’s glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. “After looking for him all day, there he was, staring up at me out of the exhibiting case,” said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view.
Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron （中队） as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there’s more to his story. “For a brief time in 1916 he was probably the most famous pilot in the world,” says Broad. “He was credited with downing Oswald Boelcke, the most famous German pilot at the time.” Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane.
McKay’s war records were destroyed during a World War II air bombing on London — an explanation for why he was all but forgotten.
But now, thanks to the efforts of Broad and his students, a marker in McKay’s memory was placed on the university grounds in November 2007. “I found my eyes filling with tears as I read the word ‘deceased’ （阵亡） next to his name,” said Corey Everrett, a student who found a picture of Mckay in his uniform. “This was such a simple example of the fact that he had been a student just like us, but instead of finishing his time at Western, he chose to fight and die for his country.”What made Professor Broad continue his search for more information on McKay?
| A．A uniform of McKay. | B．A footnote about McKay. |
| C．A book on McKay. | D．A picture of McKay. |
What did the students find out about McKay?
| A．He trained pilots for some time. |

| C．He died in the Second World War. |
| D．He was downed by the pilot Boelcke. |
McKay’s flying documents were destroyed in.
| A．Belgium | B．Germany | C．Canada | D．England |

| A．preferred fight to his study |
| B．went to war before graduation |
| C．left a picture for Corey Everrett |
| D．set an example for his fellow students |
What is the text mainly about?

So long as teachers fail to distinguish between teaching and learning , they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that“ reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private ,for learning is an occupation of the mind ,and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable ,what then can be done through teaching that will aid the child in the quest（探索）for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children. ”
When the roles of teacher and learner are seen for what they are, and when both teacher fulfil them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.The problem with the reading course as mentioned in the first paragraph is that ________.
| A．it is one of the most difficult school courses |
| B．students spend endless hours in reading |
| C．reading tasks are assigned with little guidance |
| D．too much time is spent in teaching about reading |
The teaching of reading will be successful if ________.
| A．teachers can improve conditions at school for the students |
| B．teachers can enable students to develop their own way of reading |
| C．teachers can devise the most effcient system for reading |
| D．teachers can make their teaching activities observable |
The underlined word“ scrutiny” most probably means“________”.
| A．inquiry | B．observation |
| C．control | D．suspicion |
Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient - no matter where he or she may be.
Online doctors offering advice based on norman symptoms（症状）are the most obvious example. Increasingly, however, remote diagnosis（远程诊断）will be based on real physiological data（生理数据）from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone ,it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipement, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural （countryside） care. And at least one team wants to use telemedicine as a tool for disaster need - especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth（宽带） is the limiting factor for sending complex （复杂）medical pictures around the world,—CU photos being one of the biggest bandwidth users. Communication satellites say be able to deal with the short - term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second - generation Internet and third generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer - based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’opinions and diagnosis are common.
The writer chiefly talks about ________ .
| A．the use of telemedicine |
| B．the on -lined doctors |
| C．medical care and treatment |
| D．communication improvement |
Which of the following statements is true according to the text?
| A．Patients don’t need doctors in hospitals any more. |
| B．It is impossible to send a patient’s signs over the telephone. |
| C．Many teams use telemedicine dealing with disasters now. |
| D．Broadband communications will become cheaper in the future. |
The“problem”in the fourth paragraph refers to the fact that ________ .
| A．bandwidth isn’t big enough to send complex medical pictures |
| B．the second - generation of Internet has not become popular yet |
| C．communication satellites can only deal with short - term needs |
| D．there is not enough equipment for spreading the medical care |
