The Chapramari Forest lies in the eastern area of India．1.But a large group of elephants found still-green grasses along the railway line that crosses through the forest． As the elephants got near and on the tracks at dusk， a passenger train traveling at 50mph knocked into the herd． Seven elephants were killed， and 10injured．

2.The deaths occur at hotspots in a few Indian states where trains intersect （交叉） with elephant habitats． It's puzzling why this highly intelligent animal would wait on the tracks3.．

After a collision this past April in Odisha state that killed four elephants， Indian Railways lowered speed limits to as low as 18mph in several areas in the country's east4.Beginning late last year， railways officials in the east have fixed a kind of equipment s that loudly broadcast the buzz of honeybees， a sound they hope keeps elephants away for fear of the insects． In the northern state of Uttarakhand， the forest department is using drones （遥控飞机） to keep track of animal movement．5.

More permanent solutions include constructing overpasses or underpasses as safe crossing points for the elephants， elevating the railway track， or getting the track away from sensitive areas．

Scientists at the University of Hawaii at Manoa studied a huge area in the eastern part of the Pacific Ocean known as the Clarion－Clipperton Zone，or CCZ to find and study new sea species.

Diva Amon，a researcher at the University says usually deep sea biologists think there is not a lot living in the deep sea.

“But we found that actually there is quite a lot living there，and so that was really exciting. . . ” she says.

The group is studying the area because the CCZ，a huge and flat area of seabed，is known to have valuable minerals. The International Seabed Authority (ISA) is allowing the company UK Seabed Resources Ltd. to explore the area on the Pacific Ocean floor for mining. However，the ISA said the company must first complete a biological study of the area before it can begin mining for metals. So，the company employed Amon and her group.

Amon says that more than half of the animals they collected were completely new to science. Her group discovered not only new species，but new genera (动植物的属) of animals.

Biological oceanographer Paul Snelgrove says that finding new species in the deep ocean is common. But，he said，finding a new genus “is really great”.

Amon warns that if mining happens across the whole area，the ecosystem would be largely destroyed. But，she says，we will find the least damaging way to make mining possible.

“There is a sort of scientific push to try and slow things down a bit so that the science can be done before. . . so it can be done with the least influence possible. . . ” she says.

“It’s likely we are going to develop at least some parts of these deep ocean environments and do it in a way that’s going to minimize (最小化) our influence，”says Paul.

1.What did scientists try to find out in the CCZ?

A.Whether there is life.

B.Whether there are valuable minerals.

C.What sea life exists there.

D.What metals lie under the sea floor.

2.What does Paul say about finding new sea species?

A.It’s something unusual.

B.It’s nothing to be surprised at.

C.It has a far－reaching effect on science.

D.It proves common species will change.

3.What is Amon’s attitude towards mining the CCZ?

A.Careful. B.Doubtful.

C.Unsupportive. D.Uninterested.

4.What does the underlined word “it” in the text refer to?

A.Mining.

B.A scientific push.

C.Finding the least damaging way.

D.Developing the ocean environments.

In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by an environmental protection organisation，which has contributed to improving the living environment for wild animals. Recently, the organisation has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.

In the area, the local people have planted many special flowers with the help of the organisation, aiming to see whether these flowers will interest the rare and beautiful butterflies. The Project officer Sarah Marshall says, “It will be a suitable habitat for butterflies. They are great ‘indicator species’ as they are easily affected by climate changes so they make a brillian early - warning system for the environment.” She also points out that volunteers are needed to recourd the number or species of butterflies，and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.

The organisation is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way.Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit（butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.

No previous experience is necessary as training and support will be provided，but a keen interest is essential. If you are interested, P1ease contact Sarah on (0l380) 725670，ext 278, email sarahm wiltshirewildlife. org

Underneath the Greenland ice sheet lies a body of water covering an area larger than West Virginia, and until just a few years ago, scientists had no idea that it existed.

First discovered in 2011, scientists now believe it covers some 27, 000 square miles and contains more than 100 billion tons of liquid water.

The melt-water reservoir (蓄水池) was discovered under the ice, in a south-eastern part of Greenland, by researchers from the University of Utah about two years ago. According to the BBC, at first the researchers expected to find waters stored in small spaces between the rocks. What they actually found was a massive reservoir of water trapped in the ice, kind of like the liquid in a snow-cone. Newser quotes lead study author Richard Forster saying, “we thought we had an understanding of how things work in Greenland, but here is this entire storage system of water we didn’t realize was there.”

OK, so snow water under the ice in Greenland; why is this a big deal? Well, researchers say it could provide new clues to understanding Greenland’s ice melts and sea level rise in general. Voice of America quotes Forster saying, “of the present sea level rise, the Greenland ice sheet is the largest contributor, and it is melting at record levels, so understanding the aquifer’s (地下蓄水层) capacity to store water from year to year is important, because it fills a major gap in the overall connection of melt-water runoff and sea levels.” According to researchers, the water is 15 to 60 feet beneath the surface and likely stays fluid because it’s covered by snow. They’re unsure how old the reservoir is or whether it flows into the ocean.

1.What is true about the water newly found in Greenland?

A. It is probably in the form of liquid.　　 B. It is widely stored between the rocks.

C. It finally flows into the ocean.　　 D. It came into being only a few years ago.

2.The discovery of water in Greenland is very important because ______.

A. it confirms scientists’ previous guess about the storage of water in Greenland

B. it throws new light on the relation between Greenland’s melt water and sea level rise

C. it provides information about the possible amount of water storage in Greenland

D. it solves the problem of the shortage of fresh water in the world for good

3.What will be the best title of the passage?

A. Ice Sheet in Greenland Melting at Alarming Speed

B. Greenland Ice Sheet Contributing to Rapid Sea Level Rise

C. Billions of Tons of Water Found under Greenland Ice Sheet

D. Scientists Predicting Massive Underground Water in Greenland

Forest guards in western India are using cell phones with ringtones of cows mooing, goats bleating and roosters crowing to attract leopards that have wandered into human settlements, officials said on Monday.

The wild cats in the state of Gujarat often get into villages near forests in search of food, say officials, adding that this results in attacks on people. But rather than use methods such as live bait(诱惑物) like goats tied to trees to lure the leopards, which then fall into large pits dug by guards, officials say they have found a safer method to trap the cats.

“The moos of a cow, bleating of a goat from the phone has proved effective to trap leopards,” said D. Vasani, a senior forest official in Gujarat. “This trick works.” Vasani said forest guards have downloaded the sounds of over a dozen animals as ringtones on their mobiles which they attach to speakers and fix behind a cage. They then play the ringtone continuously for up to two hours until the curious leopard appears and moves into the cage looking for its easy meal.

At least five leopards have so far been lured from villages since the new ringtone method was introduced three months ago. The cats have all been released back into forest areas.

Wildlife activists welcomed the new initiative saying that previous methods of trapping the cats using pits often resulted in the animals getting injured.

1.What can be the best title of the passage?

A．Cell Phones to Hunt Animals

B．Practical Uses of Cell Phones

C．Wildlife and New Technology

D．Phone Ringtones to Catch Leopards

2.Forest guards in India try to catch leopards mainly because ______.

A．leopards attack villagers

B．they want leopard fur

C．leopards attack animals

D．they have new ringtones

3.What will be needed to trap the leopards using the new method?

① cell phones   ②animals    ③ sounds of animals   ④ cages    ⑤large pits

American black bears appear in a variety of colors despite their name. In the eastern part of their range(地理分布区), most of these bears have shiny black fur, but in the west they grow brown, red or even yellow coats. To the north, the black bear is actually gray or white. Even in the same litter(窝), both brown and black furred bears may be born.

Black bears are the smallest of all American bears, ranging in length from 5 to 6 feet, weighing from 300 to 500 pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is shy, clumsy(笨拙的) and rarely dangerous.
