The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage seems strange to someone fortunate enough to live in a high rainfall country, many of the world’s agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution (重新分配) are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation. In Texas, farmers’ overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.

Goldie’s Secret
She turned up at the doorstep of my house in Cornwall. No way could I have sent her away. No way, not me anyway. Maybe someone had kicked her out of their car the night before. “We’re moving house.” “No space for her any more with the baby coming.” “We never really wanted her, but what could we have done? She was a present.” People find all sorts of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen.
I called her Goldie. If I had known what was going to happen I would have given her a more creative name. She was so unsettled during those first few days. She hardly ate anything and had such an air of sadness about her. There was nothing I could do to make her happy, it seemed. Heaven knows what had happened to her at her previous owner’s. But eventually at the end of the first week she calmed down. Always by my side, whether we were out on one of our long walks or sitting by the fire.
That’s why it was such a shock when she pulled away from me one day when we were out for a walk. We were a long way from home, when she started barking and getting very restless. Eventually I couldn’t hold her any longer and she raced off down the road towards a farmhouse in the distance as fast as she could.
By the time I reached the farm I was very tired and upset with Goldie. But when I saw her licking (舔) the four puppies (幼犬) I started to feel sympathy towards them. “We didn’t know what had happened to her,” said the woman at the door. “I took her for a walk one day, soon after the puppies were born, and she just disappeared.” “She must have tried to come back to them and got lost,” added a boy from behind her.
I must admit I do miss Goldie, but I’ve got Nugget now, and she looks just like her mother. And I’ve learnt a good lesson: not to judge people.

American cities are similar to other cities around the world. In every country, cities reflect the values of the culture. American cities are changig, just as American society is changing.
After World War Ⅱ, the population of most large American cities decreased; however, the population in many Sun Belt cities increased. Los Angles and Houston are cities where population shifts (转移) to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents became wealthier. They had more children so they needed more space. They moved out of their apartments in the city to buy their own homes. They bought houses in the suburbs.
Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young professionals are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possibilities that the city offers.
This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is sure: many dying cities are alive again.
.

A．They are similar.	B．They are hopeless.
C．They are alive.	D．They are different.

.
Why did American city residents want to live in the suburbs after World War Ⅱ?

A．Because older American cities were dying.

B．Because they were richer and needed more space.

C．Because they could hardly afford to live in the city.

.
According to the 4th paragraph, a great many poor people in American cities __________.

A．are forced to move to the suburbs	B．are faced with housing problems

.
We can conclude from the text that __________.

A．American cities are changing for the worse
B．the population is decreasing in older American cities	C．many people are now moving from American cities

I would like to tell you a story about my uncle Theo. He is my oldest uncle, a tall, thin, grey-haired man whose thoughts are always on learning and nothing else. He is quiet, gentle and absent-minded and with about as much sense as a child where money is concerned. Well, he applied a post in Camford University. It was a very good post and there were hundreds of candidates who applied for it, and about fifteen, including Theo, were asked to be interviewed.
Camford is a very small town; there is only one hotel in it, and it was so full that they had to put many of the candidates two in a room. Theo was one of these, and the man who shared the room with him was a self-confident fellow called Adams, about twenty years younger than Theo, with a loud voice, and a laugh that you could hear all over the hotel. But he was a clever fellow all the same and had a good post in Iscaiot College, Narkover. Well, the Dean, who was the head of the department of the University, and the committee interviewed all the candidates; and as a result of this interview, the number of the candidates was reduced to two, Uncle Theo and Adams. The committee couldn’t decide which of the two to take, so they decided to make their final choice after each of the candidates had given a public lecture in the college lecture-hall. The subject they had to speak on was “The Civilization of the Ancient Summerians”; and the lecture had to be given in three days’ time.
Well, for these three days Uncle Theo never left his room. He worked day and night at that lecture, writing it out and memorizing it, almost without eating or sleeping. Adams didn’t seem to do any preparation at all. You could hear his voice and his laughter where he had a crowd of people around him. He came to his room late at night, asked Uncle Theo how he was getting on with his lecture, and then told him how he had spent the evening playing bridge, or at the music hall. He ate like a horse and slept like a log; and Uncle Theo sat up working at his lecture.
The day of the lecture arrived. They all went into the lecture hall and Theo and Adams took their seats on the platform. And then, Theo discovered, to his horror, that typewritten copy of his speech had disappeared! The Dean said they would call on the candidates on the alphabetical order, Adams first; and the despair in his heart, Theo watched Adams calmly take the stolen speech out of pocket and read it to the professors who were gathered to hear it. And how well he read it! Even Uncle Theo had to admit he couldn’t have read it nearly so eloquently himself, and when Adams finished there was a great burst of applause. Adams bowed and smiled, and sat down.
Now, it was Theo’s turn. But what could he do? He had put everything he knew into the lecture. His mind was too much upset to put the same thoughts in another way. With a burning face he could only repeat, word for word, in a low, dull voice, the lecture that Adams had spoken so eloquently. There was hardly any applause when he sat down.
The Dean and the committee went out to decide who the successful candidate was, but everyone was sure what their decision would be. Adams leaned across to Theo and patted him on the back and said, smilingly, “Hard luck, old fellow, but after all, only one of us could win”
Then the Dean and the committee came back, “Gentlemen”, the Dean said, “the candidate we have chosen is Mr. Hobdell.” Uncle Theo had won! The audience were completely taken by surprise, and the Dean continued, “ I think I ought to tell you how we arrived at the decision. We were all filled with admiration at the learning and eloquence of Mr. Adams. I was greatly impressed. But, you will remember, Mr. Adams read his lecture to us. When Mr. Hobdell’s turn came, he repeated that speech, word by word from memory, though, of course, he couldn’t have seen a line of it before. Now a fine memory is absolutely necessary for this post; and what a memory Mr. Hobdell must have! This is why we decided that Mr. Hobdell was exactly the man we wanted! ”
As they walked out of the room, the Dean came up to Uncle Theo, who was so confused but so happy that he hardly knew whether he was standing on his head or heels; and as he shook Theo’s hand he said, “Congratulations, Mr. Hobdell! But, my fellow, when you are on our staff, you must be more careful and not leave valuable papers lying about!”

A．Good-mannered

B．Modest

C．Childish

XI'AN - China's conservation work for the endangered crested ibis（朱鹮）is facing new challenges, including an increasing mortality rate due to inbreeding, and the conflict between the need to expand natural habitats and local communities' economic interests, bird experts have warned.
The crested ibis, once widespread in Japan, China, Russia and the Korean Peninsula, almost became extinct in the first half of the 20th century.
Before 1981, when seven crested ibis were accidentally found in Yangxian county, in Northwest China's Shaanxi province, academics thought the species had been extinct in China for almost 17 years.
Due to the huge effort put into species protection since 1981, the number of crested ibis in China has risen to an estimated 1,617, including 997 in the wild, the State Forestry Administration said at a meeting on crested ibis protection in Xi'an on Monday.
However, although the ibis population exceeds 1,000, the birds are still not free from the threat of extinction, said Fang Shengguo, director of the State Conservation Center for Gene Resources of Endangered Wildlife at Zhejiang University.
“Ornithologists used inbreeding in the early stages of protection so that numbers of the precious birds could increase quickly, but that method had consequences,” Fang said.
"Studies have proved that as a result of inbreeding, crested ibis have the lowest genetic diversity of all endangered birds," Fang said.
"It means a high mortality rate and more physical defects for hatched chicks."
“The government should collect genetic information from all crested ibis and establish a genetic database as soon as possible, then design a scientific mating plan for the species,” Fang said.
So far, about 90 percent of crested ibis live in Shaanxi province, and fewer than 140 ibis live in three zoos in other parts of the country, including Beijing Zoo, according to Liu Dongping, an assistant researcher at the National Bird Banding Center of China, which is affiliated to the Chinese Academy of Forestry.
The bird has lost the ability to migrate, he said, adding that if an unexpected natural disaster occurred in Shaanxi province or an infectious disease spread through the area, the ibis population could be greatly reduced.
Experts also warned that the increased population of ibis, whether in the wild or in captivity, requires a larger and more varied natural habitat.
Rampant hunting, the massive loss of habitat caused by deforestation and the overuse of pesticides, which killed aquatic insects on which the ibis feed, are believed to be the main reasons for the sharp reduction in the ibis population before 1981.
So, in 1983, a State-level natural reserve was set up in Shaanxi province to protect the bird. But the struggle for living space between human and animal has never stopped, said Lu Baozhong, deputy director of the Shaanxi Crested Ibis Conservation Station.
"For example, ibis often look for loaches in farmers' rice fields. Sometimes their claws trample the rice seedlings. In another case, villagers discovered some land with abundant mineral resources which happened to be a habitat for ibis," said Lu, who has devoted 30 years to ibis protection.
A long-term win-win solution for ibis and local communities needs to be developed, one that would provide ecological compensation for local residents, Lu said.
