Biodiversity(生物多樣性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each other in some way, biodiversity is desirable. Any loss to the planet is actually a loss for mankind as well, and it is our responsibility to try and save Earth’s biodiversity.

Biodiversity has a vital role to play in the evolution（演變）of species. Species become extinct, but new species evolve, and this is how a balance is maintained. This may sound pretty simple, but it takes millions of years for changes to take place.

Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.

Biodiversity also has an important role to play in human society. Apart from being the most intelligent species on earth, human beings are also the most dependent. We depend on nature to meet our basic needs. When we change the balance of nature to create our cities and bring about our technical advances, we knowing or unknowing cause great damage to the ecosystem. This must be understood, and the damages must be reversed（顛倒）in any way they can to ensure that the balance of the ecosystem is maintained.

3.What does the underlined word probably mean?

A humans are as independent as they are intelligent

B the balance of the ecosystem is easily maintained

Short and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis Cricket — anything with a round ball, I was useless." he says now with a laugh. But back then he was the object of jokes in school gym classes in England's rural Devonshire.

It was a mountain bike he received for his 15^th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.

The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway's school of Adventure in Scotland, where he learned about the older man's cold-water exploits (成就). Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future. Journeys to the Pole aren't the usual holidays for British country boys, and many people dismissed his dream as fantasy. "John Ridgway was one of the few who didn't say, 'You are completely crazy,'" Saunders says.

In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter (遭遇) with a polar bear and pushed his body to the limit.

Saunders has since become the youngest person to ski alone to the North Pole, and he's skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.

This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.

1.The turning point in Saunders' life came when ________.

2.We can learn from the text that Ridgway ________.

3.What do we know about Saunders?

4.The underlined word "Intrigued" in the third paragraph probably means ________.

5.It can be inferred that Saunders' journey to the North Pole ________.
