A new study gives us the warning that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.__________ are expected to have severe water problems by the year 2025

Here’s an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What’s more, you don’t even need to touch the egg to get it to go in!
For this experiment you will need:
·a hard-boiled egg
·a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well)
·a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper
·a match
Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth.
Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze(挤) through the mouth and into the bottle.
As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直径) of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle’s opening.
Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals(封住) the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts(紧缩), and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!The best title of this passage can be .
| A．An interesting story | B．The pressure of the air |
| C．Egg in a bottle | D．Egg, bottle and match |
What don’t you need in this experiment?
| A．Eggs. | B．Water. | C．Bottles. | D．Paper. |
Why will the egg break into pieces while entering the bottle?
| A．Because of the burning paper. |
| B．Because the diameter of the egg is too larger than that of the bottles opening. |
| C．Because it is cool inside the bottle. |
| D．Because the pressure of the air inside is larger. |
What is the most important to get the egg into a bottle?
| A．A match. | B．A fruit-drink bottle. | C．The pressure of the air. | D．The burning paper. |

America has been experiencing the longest economic increase in its history. Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings.
But just a short walk from Manhattan’s skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel.
Brown is homeless——one of the 2.3 million people in the US who end up on the street.
During the day, Brown collects aluminum cans and sells them for five cents a piece. At night, he sleeps on the street.
“I have been on the street about eight or nine years, something like that,” said the 62-year-old former construction worker.
Brown admits he had problems with alcohol and has smoked cocaine. But he said he still wants a more stable housing arrangement. He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available.
However, he sees no hope of finding affordable housing in New York.
With the strong economy and unemployment down, beautiful housing is being built to meet demand.
A US report shows rents in New York City rose more than 27 per cent, from ＄549 to ＄700 a month.
One of the side effects of the strong economy is that rents have been going up.
The majority of people who experience homelessness really just need some affordable housing help.
But few housing companies are building for the poor. Many small apartments in the city now rent for ＄1,500 a month or more.
Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her. She is angry about his drinking and won’t allow it in her house.
Smiling, he said he also has seven grandchildren whom he’d like to see more often. “All I’ve got to do is clean up my act,” he said.What kind of life does George Brown lead?
| A．Stable. | B．Dangerous. | C．Hard. | D．Comfortable. |
It can be inferred from this passage that .
| A．America is short of housing companies |
| B．the poor can’t benefit from the increasing economy |
| C．poor people in America will become rich |
| D．housing companies will build more houses for the poor |
The underlined part “clean up my act” in the last paragraph means “”.
A. remove my cans B kick my bad habits
C. make a lot of money D. see my grandchildrenWhich part of a newspaper is the passage possibly taken from?
| A．Society. | B．Science. | C．Arts. | D．Business. |
Teresa was born in Yugoslavia on August 27,1910. Her parents were Albanians(阿尔巴尼亚人) and member of the Roman Catholic Church. When she was seven years old, her father was murdered. She decided not to be filled with hate because of this tragedy(悲剧). Instead, she would seek a life of love. This ambition led her to Ireland where she became a nun(修女) at the age of eighteen.
After only one year of training, she was sent to India to teach in a school called Loretto House, where the students were mostly from rich Indian families. After 15 years there, she left her duties as a teacher to “follow Christ into the slums(贫民窟).” Her heart led her away from the rich to the needs of the poor. She was then 36 years old.
Teresa no longer was affiliated(隶属) with the Irish nuns who sent her to Loreto House but worked independently. However, her work was recognised by the Pope in Rome for she still was a nun. He allowed her to set up her own group, which was called the Missionaries of Charity(仁爱传教修女会).
She no longer dressed as a nun in the European or Irish tradition. Instead, she put on a sari, the local dress of the Indian people. At first, people were sceptical(怀疑的) about her motives. Soon, they realised she was really interested in loving poor people, even those who were dying and had no chance of survival.
Soon, other Indian people began to spare time to help Mother Teresa. She had taught everyone that the poor and dying people need love most of all.
In 1979, she won the Nobel Peace Prize.Why did Mother Teresa become a nun?
| A．Her father was killed. | B．The hate of her father’s death. |
| C．She was looking for a life of love. | D．The poor life of her childhood. |
Why did she leave her duties as a teacher after 15 years in Loretto House?
| A．To be a teacher was too tired | B．The students in Loretto House were rich. |
| C．She was tired of teaching. | D．The poor in the slums needed her care. |
Which of the following is WRONG?
| A．Mother Teresa was a Catholic. |
| B．“Sari” is an Indian word that means clothing. |
| C．At first people didn’t believe her motives. |
| D．She served poor people in the slums as a teacher. |
Perhaps the most important lesson the world has learned from Mother Teresa is .
| A．regular assistance | B．food and shelter |
| C．to care for the poor of the earth | D．protection |
Haisong Jiang, who slipped (偷偷溜进) past a security checkpoint(安全关卡) on Jan. 3, causing a shutdown of Newark Airport, tried to apologize for his mistake.
" I feel guilty about this serious mistake. At that moment, I was very excited with my girlfriend, and I didn't think too much," Mr. Jiang, 28, said Tuesday in his first interview since causing the six-hour shutdown at the airport.
On Tuesday, Newark Municipal Court judged that besides the community service, he must pay a $500 fine (罚金) and $158 in court fees. In an agreement between the court and Mr. Jiang's lawyer, Mr. Jiang will pay off his money punishment all by community service instead.
Haisong Jiang, a native of China, about a year ago moved to the United States in 2004 to study and met his girlfriend, also Chinese and 26. She has since moved to California.
The lovebirds did the town over the Christmas holidays: shopping in SoHo, visiting the tree at Rockefeller Center, celebrating New Year's Eve in Times Square - the works. On Jan. 3, he watched her pass through security, but he wanted to spend more time with her. When he noticed the officer leave his post, he saw his chance, he said. He slipped under the rope and kissed her and, arm in arm, walked her to her Continental Airlines gate and saw her onto the jetway. "And immediately I left," he said.
Three days passed. "Friday, the police found me," the future scientist said. He was at the gym when his roommate called to say two police officers were at their home. "It's not right to enter the airport. Immediately I know the police want to ask me this thing."
He expects to serve half of 
his community service in a soup kitchen - "I like to cook" - and the other half in a hospital. He plans on moving to California to be with her and work in a laboratory after completing his degree in May or June.
He never types his name into search engines on the Net: the number of hits is shocking.
What’s the best title of the passage?
A. A moving love story B. An escape fr
om security check
C. A kiss causing great trouble D. When a man loves a woman
