【题目】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 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.

【1】 are expected to have severe water problems by the year 2025.

A. 46 countries B. 18 countries

C. 28 countries D. No countries

【2】 All the following are true except .

A. Lack of water may cause conflict between countries

B. New industries need a lot of water

C. There are solutions to the water problem

D. Egypt now has enough fresh water

【3】.What can be inferred from the passage? .

A. There is connection between providing clean water and slowing population growth

B. Lack of water may also result from international conflict

C. The ability of developing has nothing to do with lack of water

D. It is not known whether diseases have something to do with lack of water

【4】The best title of the passage would be .

A. World Conflict B. World Water Shortage

C. Diseases and Water D. Population and Water

【题目】Dolphins call out the specific names of loved ones when they become separated, a study finds.Other than humans, they are the only animals known to do this, according to the study.The big difference with dolphins is that these communications consist of whistles(鸣叫), not words.

Earlier research found that dolphins have a “signature whistle” that would be somewhat like human shouting, “Hey everybody! I’m an adult healthy male named George, and I mean you no harm.”

The new finding is that dolphins also say the names of certain other dolphins.“Animals produced copies of the same sound when they were separated from a close partner.This supports our belief that dolphins copy another animal’s signature whistle when they want to reunite with that animal,” Stephanie King, who led the study, says.

King and her colleagues collected acoustic(声音的)data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009.The researchers also studied four adult male dolphins housed at the Seas Aquarium, also in Florida.

Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins.

“A dolphin uses its signature whistle to broadcast its identity and announce its presence.The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other,” King explains.“Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency(频率).”

The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated.These “names” are always used in positive situations, and are only directed toward loved ones.

While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system.

【1】The underlined word “housed” in Paragraph 4 probably means “_________”.

A.raised B.saved C.discovered D.hunted

2】Which one plays a part in whether dolphin whistles can be heard over a distance?

A.The dolphin’s identity.

B.The water temperature

C.The whistle frequency.

D.The dolphin’s age.

3】When do dolphins copy the signature whistles of loved ones?

A.When there is a fight.

B.When their keeper comes.

C.When they are apart.

D.When they are hungry.

4The passage probably is taken from______

A.A magazine about scientific advances.

B.A website about various animals.

C.A report on animal acoustics.

D.An essay about the relationship between humans and animals.

Dear Lisa,

There is nothing wrong with you and this boy be friends and studying together. Of course a boy and a girl can be good friend. Ending your friendship with this boy would be stupid thing to do. You would lose a good friend and someone to study for.

Teenagers are like to gossip, and they often see something which isn't real. Perhaps your classmates can understand your friendship with the boy. However, there has no reason to stop it. My advice is to ignore your classmates. That way you will show us that you are much grown-up than they are.

Yours,

Miss Wang

【题目】There are 67 counties in the state of Alabama. Each county is rich with history and its own unique stories. Colbert County, located in the northwest corner of the state, has its share of exciting stories and claims to statewide fame. The county was created on February 6, 1867, and Tuscumbia became the county seat (the town in which the offices of the county government are located).

One of the most famous residents of Tuscumbia was Helen Keller. Helen Keller was born on June 27, 1880. Her home was a white frame cottage built by her grandparents. Since ivy (常春藤) grew everywhere, the house was called Ivy Green. It was here, at the water pump in the backyard, that Keller learned the word “w-a-t-e-r” with the help of her teacher, Anne Sullivan. Visitors to Ivy Green can walk under boxwood trees that are 150 years old. The home has furniture that the Keller family used. It also has Keller’s Braille (盲文) books and her original Braille typewriter.

Spring Park is Tuscumbia’s most popular park and favorite tourist attraction. This park has the world’s largest manufactured waterfall called Coldwater Falls. The Spring Park Light and Water Show is an amazing sight to see. It takes place every Friday, Saturday, and Sunday at sundown. The water appears to dance to music and colored lights. The music played during the show is recorded by singers and musicians from Alabama.

Fame Recording Studios is in the city of Muscle Shoals in Colbert County. The studio is the first successful recording studio in Alabama. It is best known for creating “Southern rock,” “Southern soul,” and “county soul.” Well-known performers like Aretha Franklin and musical groups such as Alabama and Lynyrd have made recordings at this studio.

Visitors can continue to explore music in Alabama by visiting the Alabama Music Hall of Fame in Tuscumbia. Built in 1990, this site recognizes the musical talents of more than 500 Alabama residents in a wide variety of musical styles, including country and rhythm and blues.
