The sixth mass extinction of life on the Earth is unfolding more quickly than feared, scientists have warned. More than 30 percent of animals with a backbone — fish, birds, amphibians, reptiles and mammals — are declining in both range and population, according to the first comprehensive analysis of these trends.

Around a decade ago, experts feared that a new range wipeout of species was appearing. Today, most agree that it is underway — but the new study suggests that the die-out is already growing fast.

The loss of biodiversity has recently accelerated. Several species of mammals that were relatively safe one or two decades ago are now endangered, including cheetahs, lions and giraffes, the study showed.

There is no mystery as to why: our own ever-expanding species — which has more than doubled in number since 1960 to 7.4 billion — is eating, crowding and polluting its planetary cohabitants out of existence. By comparison, there are as few as 20,000 lions left in the wild, less than 7,000 cheetahs, 500 to 1,000 giant pandas.

The main drivers of wildlife decline are habitat loss, over-consumption, pollution, other species, disease, as well as hunting in the case of tigers, elephants, rhinos and other large animals prized for their body parts.

Climate change is thought to become a major threat in the coming decades, with some animals — most famously polar bears — already in decline due to rising temperatures and changing weather patterns.

1.What does the underlined word “accelerated” in Paragraph 3 mean?

A. Made up.　　 B. Put up.

C. Sped up.　　 D. Used up.

2.Why has the loss of biodiversity sped up?

A. The mankind’s population is growing fast.

B. The air pollution is too severe.

C. There are fewer species in larger areas.

D. Man causes wider water pollution.

3.Which is not the main driver of wildlife decline?

A. Outside animals.

B. Loss of living areas.

C. Various illnesses.

D. Lack of water.

4.How is the future of polar bears?

A. Uncertain.　　 B. Hopeful.

C. Doubtful.　　 D. Unsatisfying.

It was created by US politician Gaylord Nelson, aiming to give a voice to people who wanted environmental protection. 1. Back then, it helped to bring clean air and water laws to the US. Now a global movement, it's facing even bigger environmental threats.

For us, plastic is an item we use and then throw away. But if you throw away a plastic bottle today, it is non-biodegradable (不可生物降解的).It will still be around for hundreds of years. Much of this plastic waste ends up in the sea, where it kills more than 100 million sea creatures every year. 3.

Some scientists believe that one of the most intelligent beings on Earth is in fact the octopus (章鱼).

Octopuses usually live at the bottom of river mouths and seas-areas which are not attractive to researchers. They are not social animals so it can be hard to study their interaction with others. And the octopus’ intelligence is not easy for humans to understand. When we observe some animals such as rats or dogs, we can often understand their behavior. Octopuses，however can seem like aliens (外星人). Scientists need to have a lot of imagination to understand what an octopus is thinking!

In the 1950s, the US Air Force sponsored scientists to study the way octopuses use their brains. They hoped that they could use this knowledge to help them build better computers. However, their brains were so complex that the scientists felt it of no significance to continue with it. Octopuses have a very complex nervous system and recent research suggests that they have some of their intelligence inside each arm, which means that each arm can “think” for itself. It also appears that they have a good memory, perhaps similar to a cat’s.

Perhaps the most striking thing about octopuses is their ability to change their color and body pattern. They do this to camouflage themselves to avoid their enemies and also to communicate with others. They can completely change their appearance in less than a second. It can change its skin to look like rocks, sand or planktron (浮游生物).

Some scientists have even suggested that these different patterns and colors are in fact a very hard language-and that each design is a different verb，adjective or noun. But nobody has been able to work out what they might be saying. There’s a long way to go to get to know the octopus completely.

1.What can we infer about the octopus’ intelligence from Paragraph 2?

A.It does not attract scientists. B.Little has been known about it.

C.It is equal to the cat’s or dog’s. D.Much has been done about it.

2.What can we say about scientists’ study on the octopus in the 1950s?

A.They had to give it up eventually. B.They used computers to help.

C.They found its arms could think. D.They judged it lived like a cat.

3.What does the underlined word “camouflage” in Paragraph 4 probably mean?

A.Relax. B.Strengthen. C.Hide. D.Express.

4.What does the author think of the octopuses?

A.They are the smartest animals. B.They’re easy to be seen in the sea.

C.It is useful to copy their language. D.It is difficult to understand them.
