While elephants born without tusks (长牙)are not unheard of,they normally form just 2 to 6 percent of the population. However, that is not the case at Mozambique’s Gorongosa National Park, where an astonishing 33 percent of female elephants born after the country’s civil war ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behavior expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivory.
Poole says before the country’s 15-year-long civil war, the 100,000-acre park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivory to help finance weapons (武器)and meat to feed the soldiers. Of the less than 200 survivors, over 50 percent of adult females had no tusks. Therefore, it is not surprising that the park’s tuskless elephant population has grown greatly.
This is not the first time researchers have observed a great change in the population of elephants. At Zambia’s South Luangwa National Park and Lupande Game Management Area, areas which were heavily hunted in the 1970s and 1980s, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivory.
The recent ban on ivory in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females, to change the trend.
1.What is the probable cause of the phenomenon mentioned in Paragraph 1 ?
A. Illegal hunting. B. Constant farming.
C. A pure coincidence. D. Natural evolution.
2.Why did people kill so many elephants during the civil war in Mozambique?
A. To get funds by selling ivory.
B. To develop new weapons.
C. To provide food for local people.
D. To make ivory products.
3.Which of the following had the earliest record on tuskless elephants?
A. Gorongonsa National Park.
B. South Luangwa National Park.
C. The Ruaha National Park.
D. Lupande Game Management Area.
4.What does the underlined phrase “the trend” in the last paragraph refer to?
A. Elephants facing greater danger.

高二英语阅读理解中等难度题查看答案及解析
Elephants born without tusks(长牙) normally make up just 2 to 6 percent of the herd population. However, that is not the case at Mozambique’s Gorongosa National Park, where 33 percent of female elephants born after the country’s civil war ended in 1992 are tuskless. While that might be just a coincidence(巧合), Joyce Poole, an elephant behavior expert, has another theory.
The researcher thinks we may be witnessing an unnaturally evolution of the species due to the hunting of the elephants for their valuable tusks. Unlike our permanent teeth, tusks of elephants grow throughout the animal’s life, becoming longer and thicker with age. For decorative purposes, poachers usually first target older males due to their impressive tusks, and females are not spared either. As a result, in areas where hunting goes unchecked for long, the number of tuskless females increases. This allows them to gain a biological advantage, resulting in a larger than average population of female offspring (后代)with no tusks.
Poole believes this phenomenon explains the rise in the number of tuskless females at Gorongosa National Park. The researcher says before the war, the park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 percent of the elephants had been slaughtered for tusks to help finance weapons and meat to feed the soldiers. Of the less than 200 survivors, over 50 percent of the females had no tusks. Hence, it is not surprising that the park’s tuskless elephant population has grown greatly.
So far, the hunting has largely influenced female elephants. Poole explains, “Very few males are tuskless because males require tusks for fighting. Without tusks, males have a much harder time breeding and do not pass on their genes(基因) as often as tusked ones.” If the hunting of males for tusks continues at this pace, it could result in a generation of elephants with much smaller tusks.
1.How does the writer draw readers’ attention to the topic?
A.By comparing figures. B.By offering explanation. C.By giving an example. D.By introducing an expert.
2.What might be the reason for the increase of tuskless females?
A.Illegal hunting. B.Pure coincidence.
C.Natural evolution. D.Effective protection.
3.What does the underlined word “slaughtered” in Paragraph 3 mean?
A.Raised. B.Protected. C.Killed. D.Trained.
4.What is the text mainly about?
A.The future of African elephants.
B.The protection of African elephants.
C.The increasing number of tuskless elephants.
D.The genetic consequence of hunting elephants.
5.In which section of a newspaper may this text appear?
A.Health. B.Science. C.Education. D.Finance.

While elephants are respected by the people of Thailand, they are also used as beasts of burdens (驮兽). Today, these majestic animals are extensively used to help carry wood for the logging industry. It is therefore nice to hear that on National Elephant Day the mighty mammals are treated like a king, and served with meals fit for a king.
One of the biggest celebrations took place at the Pattaya Resort in Thailand’s Chonburi Province. Fifty-two elephants, some wearing beautiful clothes, arrived bright and early (大清早) for the big day. Each was first blessed with holy water by a professional elephant rider and then led to the grand feast, which served an unlimited supply of their favorite treats—bananas, dragon fruits (火龙果), pineapples, assorted melons, apples and the list went on and on! The elephants ate till they were satisfied before walking back with their owners for a good night’s rest.
Though called National Elephant Day, the celebrations that took place on March 13th this year stretched out for an entire week. Besides providing a well-deserved treat and break for the hard-working animals, the celebrations were also aimed to raise awareness about the mammal’s dwindling (减少的) population. One smart elephant even helped show the message by painting a dead elephant and the words “Don’t kill me”, right beside it .
And horrible as the message may sound, there is a sad ring of truth to it. Since the 1900s the number of elephants in Thailand has gone from over 100,000 to just 3,000-4,000 because of the destruction of their natural habitat and illegal killing. Asian elephants are not the only ones that are in trouble. African elephants are facing the same fate (命运). Hopefully, the public and officials are now working together to save these mighty animals from disappearing from the world.
1.Nowadays elephants in Thailand are
A. still used to help fight battles
B. never used as beasts of burdens
C. used to do tasks that need strength
D. less respected because of the development of the society
2.The celebrations held at the Pattaya Resort aimed to ______.
A. show visitors the elephants’ great performance
B. honor elephants for their devotion to the country
C. encourage people to play with elephants
D. show visitors the beautiful scenery in Thailand
3.The underlined word “it” (Para 3) probably refers to_______.
A. the elephant rider
B. the words “Don’t kill me”
C. the elephant that was painting
D. the dead elephant
4.What can we learn from the text?
A. Elephants are protected very well in Thailand.
B. Elephants also face the risk of being killed in Thailand.
C. The number of elephants is increasing gradually in Thailand.
D. Elephants could enjoy a grand feast every week in Thailand.

Hank Viscardi was born without legs. He had not legs but stumps(残肢)that could he fitted with a kind of special boots. People stared at him with cruel interest. Children laughed at him and called him ‘Ape Man’ (猿人) because his arms practically dragged on the ground.

There were times when he fell down on the floor, but he pulled himself up and went back to the endless marching. He went out on the street. He climbed stairs and learned to dance. He built a boat and learned to sail it.
