Animal conservation

Many animal and plant species have become extinct and many more are in critical danger.Finding ways to protect the earth's wildlife and conserve the natural world they inhabit(居住)is now more important than ever.

Dodos

The Dodo is a classic example of how human caused damage to the earth's biology.The flightless Dodo was native to the Island of Mauritius in the Indian Ocean.It　 lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505.The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the Island by humans such as pigs, monkeys and rats.The population of Dodos rapidly decreased and the last one was killed in 1681.

Rhinos

The Rhino(犀牛)horn is a highly prized item for Asian medicine.This has led to the animal being hunted in its natural habitat.Once widespread in Africa and Eurasia，most Rhinos now live　 in protected natural parks and reserves(保护区)．Their numbers have rapidly decreased in the last 50 years，and the animals remain under constant threat from poachers(偷袭者)．

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain.As few as 1，600 pandas remain in the wild.The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison.However，the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animal's continued existence.

Whales

The International Whaling Commission is fighting to ensure the survival of the whale species.Despite the fact that one－third of the world's oceans have been declared the whale sanctuaries(保护区).7 out of 13 whale species remain endangered.Hunted for their rich supply of oil，their numbers have decreased to just 300.Collisions with ships，poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

Tigers

The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5，000 and 7，000 and The Bali，Javan，and Caspian tigers are already extinct.The South China tiger is precariously close to disappearing，with only 20 to 30 still alive.Like the Rhino horn，tigers' bones and organs are sought after for traditional Chinese medicines.These items are traded illegally along with tiger skins.

高一英语单项填空中等难度题查看答案及解析

Imagine you are in a jumping contest. Animals and insects can also enter this contest. But they might just leave humans in the dust!

The first event is the long jump. The human athlete is Mike Powell. In 1991, he jumped nearly 30 feet, which is the world record for the long jump. That is about five times his own height.

His competitor in the long-jump contest is a frog named “Rosie the Ribbiter.” Rosie set the world record for frogs in 1986 by jumping more than 21 feet. Her record has never been broken by any other frog. Compared to Mike Powell, Rosie’s jump is not that amazing. But wait! Rosie is only about 10 inches long when her legs are stretched to their full length. She can jump more than 25 times her size. Rosie, the frog, wins the long-jump event.

The next event is the high jump. Javier Sotomayor, the world record holder, can jump a bar (横杆) 8 feet high. That is about as high as the ceiling in most homes.

Looking around for someone to challenge his record, Javier might need a magnifying glass (放大镜). The next contestant is a tiny insect called the spittlebug (吹沫虫).

The spittlebug can jump 28 inches into the air. It is only a quarter-inch long, less than the width of a pencil. If the spittlebug were the same size as Javier, it would be able to jump 600 feet into the air. That is like a human jumping over a building 55 stories high!

Though the humans lose the “jumping contest,” their competitors would probably agree that Mike and Javier are still pretty excellent athletes. If only Rosie and the spittlebug could speak!

1.The underlined word “contestant” in Paragraph 5 means “_____”.

A. coach            B. teammate            C. challenger        D. record holder

2.What can we learn about the spittlebug?

A. It likes living on the ceiling.

B. It is good at flying in the air.

C. It is the same length as a pencil.

D. It has a wonderful jumping talent.

3.In the author’s opinion, Rosie and the spittlebug’s jumping abilities are ________.

A. surprising        B. promising        C. doubtful            D. fearful

4.How does the author develop the text?

A. By giving instructions.

B. By making comparisons.

C. By following the order of time.

D. By following the order of importance.
