A new study warns 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 twentyeight countries. Most of the countries are in Africa or the Middle East.
PAI 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 the 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 water is not safe. Mr Engelman says there are problems all over the world because some diseases, such as cholera, are carried in water. Lack of water may also result in more international conflicts. 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 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.From the first four paragraphs, we can learn __________.

Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.The first paragraph is mainly about .

Poetry is an interesting form of writing. It is very free, has few restrictions and can be a great way to express feelings. Writing a poem is all about observing the world within you or around you.
To write a poem, first you should begin with an idea or inspiration. Inspiration may come at any time unexpectedly. It may be a specific person, place or thing that causes some sort of strong emotion. It may be more of an abstract idea or release of emotion.
After getting the idea, you can write down everything that comes to mind. Don’t think much and let all feelings pour out. Remember everything can be thrown out later.
Then, you can think about its form and begin to organize thoughts. Poetry comes in many forms, from epic poetry that has a story to dramatic poetry intended to be performed. Try them all out. One will come naturally. Maybe different poems fit different forms. When you write a poem, think about both meter (韵律) and rhythm carefully, which are equally important in poetry. Meter is the fixed pattern of the poem, while rhythm refers to the sound when it is spoken. It is also important to use a lot of descriptive words. Create imagery (意象) with words, trying to make them attractive to all the senses. For auditory (听觉的) interest, try repeating of similar sounds in a sentence or phrase. All of this adds life and interest to a poem.
After you finish your work, don’t be afraid to share your work with others. When others point out your weakness, accept and grow from it.What does the underlined word “restriction” in Paragraph 1 probably mean?_______
| A．Change. | B．Order. | C．Limitation. | D．Organization. |
When you begin to write a poem, you should first .
| A．begin with some specific persons | B．come up with an idea |
| C．describe a famous place | D．organize your thoughts |
We can infer from the text that .
| A．writing poems needs imagination and the ability to use language well |
| B．people can get more ideas if they often share their poems with others |
| C．people should first learn to write epic poetry, then dramatic poetry |
| D．people need to write down every feeling they want to release at a time |
What’s the purpose of the text?_________
| A．To tell readers how to write a poem. |
| B．To encourage more people to write poems. |
| C．To show what quality a good poem should have. |
| D．To teach people how to appreciate poems. |
The history of modern art begins with Impressionism, a movement started in Paris in the mid-1800’s. At that time many artists painted in a very traditional way that involved spending hours in a studio, painstakingly (辛苦地) creating paintings that were extremely detailed. These paintings were sometimes of people or landscapes or historical events. In 1863, Edouard Manet exhibited his painting “Dejeuner sur l’erbe” at the Salon des Refuses. The painting caused a commotion (骚动), thus starting the Impressionist movement. Although Edouard Manet is the declared leader and founder of the group, he was not present at the first group exhibition or any of the other eight collective Impressionist shows. The movement gained more attention in the April of 1874 when Claude Monet, Auguste Renoir, Alfred Sisley, and Jean-Frédéric Bazille formed Society of Artists, Painters, Sculptors, Engravers and began exhibiting outside of the official salon. The same year, the term Impressionism was invented by criticizing (批评的) journalist Louis Leroy to describe their paintings, who worked for the magazine Le Charivari.
The Impressionists often paint out of doors and want to show how light and shadow fall on objects at particular times of the day. Their works are sometimes described as “captured moments” and are characterized by short quick brushstrokes (笔) of colour which, when viewed up close looks quite messy and unreal. If we step back from the Impressionist paintings, the colours are blended together by our eyes and we are able to see the painters’ subjects which often show colourful landscapes, sunlight on water as well as people busy with outdoor activities.Before Impressionism, the works of artists were .
| A．quite abstract | B．very confusing |
| C．very detailed | D．quite controversial |
Who first started Impressionism? ___________
| A．Claude Monet. | B．Edouard Manet. |
| C．Auguste Renoir. | D．Alfred Sisley. |
The works of the Impressionists are best viewed .
| A．with imagination | B．at a distance |
| C．outdoors | D．in a studio |
The second paragraph is mainly about ______.
| A．the painting style of the Impressionists |
| B．how to describe the Impressionist paintings |
| C．the influences of the Impressionist paintings |
| D．the subjects of the Impressionist paintings |
We are all busy talking about and using the Internet but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1970s, universities, hospitals, and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet easier.
Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mails is more and more popular among young people.
The Internet has now become one of the most important parts of people’s life.

The Coalition for the Homeless is an organization that seeks to address the needs of the homeless population in the United States. It is a network of offices, some of which provide food and houses for the homeless population, and some of which fight for the passing of laws that would give every American the right to a place to call home. According to the Coalition’s studies, of over two hundred million people living in the United States, up to three million are homeless—and the number is still growing. Since the late 1970s, fast-rising house prices, large cuts in government supported housing programs, and economic recession(经济衰退) have make it impossible for many Americans to meet housing costs. Sadly, this has resulted in a number of persons being forced to leave their homes and/or unable to find new affordable homes. According to another research, families with children appear to be the fastest-growing part of the homeless population, making up 39% of it. The old idea of a homeless person, that of the single man who gets drunk all the time, is no longer true. A much larger part of the population now finds itself homeless. Even worse, once a person becomes homeless, he often finds it impossible to find a job, since most employers require anyone who wants a job from them to provide a home address on a job application.The word “ address” in the first line probably means “ ________”.
| A．talk about | B．write to | C．fight for | D．deal with |

Homeless people often have difficulty finding a job because_______.
| A．they often don’t have enough work experience |
| B．they mostly have a drinking problem |

What’s the main cause of the rising number of the homeless in the U.S.?
| A．The passing of new housing laws. |
| B．The ever-rising price of housing. |
