Have you ever wondered what wild animals...

    Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the “private” moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.

Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.

Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.

Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.

Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California’s Channel Islands.

However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.

1.Which of the following helps scientists know about climate change?

A. How active animals are. B. What animals eat.

C. Where animals go. D. When animals move.

2.Where are the cameras fixed?

A. Under water B. In the field

C. On GPS devices. D. On wild animals.

3.What may be the disadvantage of the rural cameras?

A. They affect animals' search for good.

B. They make wild animals puzzled.

C. They make animals attack one another frequently.

D. They might bring danger to animals.

4.Which of the following can be the best title for the text?

A. Cameras Record Animals in the Wild B. Every Coin Has Two Sides

C. Animals No Longer Have Secrets D. An Invention Makes Animals Mad

 

1.C 2.B 3.D 4.A 【解析】 本文属于科普文,主要讲述相机被用于观察野生动物迁徙的途径和行为,可以观察到气候变化对动物的影响,但是相机对动物也有不好的影响,主要体现在帮助猎人捕猎动物。 1.细节理解题。根据第三段For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home.可知,长鼻浣熊等动物被相机捕捉到出现在正常活动范围以北的地方,故可知,通过观察动物的迁徙方向可以看到气候变化的影响,故选C。 2.细节理解题。根据第四段These cameras can be left in very rural (荒野的) areas for days, weeks or even month.可知,相机被放在荒野地方几天,几周甚至一个月,故选B。 3.推理判断题。根据最后一段Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way.可知,相机同样被用于帮助猎人寻找动物,这对动物会产生危险,故选D。 4.主旨大意题。本文主要讲述相机被用于观察野生动物迁徙的途径和行为,可以观察到气候变化对动物的影响,但是相机对动物也有不好的影响,主要体现在帮助猎人捕猎动物,故选A。

    A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional (3-D) printing to re-create famous paintings so that they can be touched.

One painting printed with the new technology is Gustav Klimt’s “The Kiss.” It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.

Klimt finished the painting in 1908. Until now, people who have trouble seeing can not enjoy the artwork. But thanks to the reproduction (复制品) they can touch the piece and feel the ridges (隆起) and depressions (凹地). Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple’s robes are so detailed (精细的).

Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it, she said, “Exactly, can you see these? There are so many details.” Raditsch said she can imagine what the original painting looks like when she touches the reproduction. “It’s somehow round. You can feel it. It comes with it. And in many places it’s so smooth. And then I think to myself: it probably shines too!” Raditsch said.

The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.

1.What is “The Kiss”?

A. A European Union project. B. A popular painting

C. A 3-D technology. D. A famous museum.

2.Why did Reichinger say this reproduction was difficult to finish?

A. The painting was reproduced detailedly.

B. The original artwork was made in 1908.

C. Blind art fans can’t download the source files.

D. The 3-D technology is not available.

3.What is the best title for the text?

A. A European Union Program for Museum Visitors

B. How to Reproduce the World-famous Paintings

C. A Special Museum for Art Fans in Vienna, Austria

D. 3-D Printing Lets the Blind Experience Famous Paintings
