Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. 71 Sharks eat fish, other sharks, and plants that live in the ocean.

Sharks grow slowly. About forty percent of all sharks lay eggs. 72 Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old．Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.

Sharks are important for the world’s oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too great. 73.

People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.

Collectors pay thousands of dollars for the jaws of a shark. 74 The skin of a shark can be used like leather.

In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth.75.

E．If too many sharks in one area are killed, that group of sharks may never return to normal population levels

F． his is a threat to other forms of life in the ocean.

G．The others give birth to live young

Obtaining Fresh Water from Icebergs

  The idea of getting fresh water from icebergs that are moved to populated areas or places was once treated as a joke. Recently, scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food.___ 1.___

Glaciers are a possible source of fresh water that has been overlooked until recently. __2.__It contains fresh water so much that it could sustain(维持) all the rivers of the world for 1,000 years. Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year.__ 3.__ However, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator(赤道) in the Atlantic Ocean. __4.__ The difficulty exists such as its rapid melting in warmer climates. __5.__

A. Icebergs are not like sea ice, which is formed when the sea itself freezes.

B. Now it is being considered quite serious by many nations.

C. 7,659 trillion metric tons of ice are floating on the sea every year.

D. But the water they could provide would be far cheaper than that produced.

E. To move them to dry parts of the world would not be too difficult.

F. It is not a dream to get water from icebergs.

G. Three-quarters of the Earth’s fresh water supply is still tied up in glacial ice.

An Australian man who has been donating his extremely rare kind of blood for 56 years has saved the lives of more than two million babies.

James Harrison has an antibody in his plasma（血浆）that stops babies dying from Rhesus disease, a form of severe anaemia. He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father's blood.

Mr. Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations. When he started donating, his blood was deemed so special that his life was insured for one million Australian dollars.

He was also nicknamed the “man with the golden arm” or the “man in two million”. He said, “I've never thought about stopping. Never!” He made a pledge to be a donor aged 14 after undergoing major chest surgery in which he needed 13 liters of blood. “I was in hospital for three months,” he said. “The blood I received saved my life so I made a pledge to give blood when I was 18.”

Just after he started donating he was found to have the rare and life-saving antibody in his blood. At the time, thousands of babies in Australia were dying each year of Rhesus disease. Other newborns suffered permanent brain damage because of the condition. The disease creates an incompatibility between the mother's blood and her unborn baby's blood. It stems from one having Rh-positive blood and the other Rh-negative.

His blood has since led to the development of a vaccine called Anti-D. After his blood type was discovered, Mr. Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine. “They insured me for a million dollars so I knew my wife Barbara would be taken care of,” he said. “I wasn't scared. I was glad to help. I had to sign every form going and basically sign my life away.”

Mr. Harrison is Rh-negative and was given injections of Rh-positive blood. It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women. It has also been given to babies after they are born to stop them developing the disease.

It is estimated he has helped save 2.2 million babies so far. Mr. Harrison is still donating every few weeks now.

1.What does the underlined phrase “two million” refer to?

A．mothers          B．babies            C．dollars            D．blood

2.Why did James decide to donate his blood? Because _____.

A．his daughter asked him to help her son

B．he has a golden arm worth a million dollars

C．a vaccine called Anti-D is to be developed

D．someone else’s blood saved his life

3.The sentence “The disease creates an incompatibility between the mother's blood and her unborn baby's blood” (underlined in Paragraph 5) suggests that _____.

A．the mother and the baby have different types of blood

B．babies suffer permanent brain damage before born

C．Rhesus disease contributes to permanent brain damage

D．all the patients have a rare antibody in their blood

4.What can we infer from the sixth paragraph?

A．His wife Barbara needed to be taken care of badly then.

B．Mr. Harrison was not glad to help develop a new vaccine.

C．Some of the tests to develop the vaccine are dangerous.

D．His blood type was accidentally discovered after tests

Pregnancy(妊娠) and childbirth kill more than 536,000 women a year. More than half of the cases happened in Africa, according to the World Health Organization. In fact, most of the deaths are preventable with basic medical care.
The five leading causes are bleeding, infection, high blood pressure, long­time labor and bad abortions (流产). Mothers' deaths from such causes were largely reduced nearly a century ago in developed countries.
Experts say that what kill many women are “the three delays”— the woman's delay in deciding to go to the hospital, the time she loses traveling there and the hospital's delay in starting treatment. Only about 15 percent of births have dangerous complications(并发症)．
Women lack education and information about birth control. Husbands and in­laws, may decide where a woman gives birth and insist that she stay at home to save money. However, there is no single solution to a problem with so many factors—shortages of doctors, nurses, drugs, equipment, roads and transportation—though hospital officials are trying many things now.
One stopgap measure to solve the problem for the present has been to train assistant medical officers, to perform certain operations. Some African countries are now struggling to train more assistants and midwives (接生婆) , and provide places for pregnant women to stay near hospitals.
But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital. More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle emergencies.
【小题1】Which is not included in the five leading causes of women's deaths during pregnancy and childbirth?
