The captain of the ship， the Beagle， wanted to find someone who would benefit from the chance of visiting distant countries. A young man 1 had left medical school without completing his degree answered the call. He received a letter 2 （predict） that he would be “ 3 disgrace to yourself and all your family”. However， the journey was full of important scientific 4 （discovery）.

The journey gave the young man the chance 5 （study） various living things in their natural environments. He noticed that some species of animals were very similar， and guessed that maybe animals evolved as they adapted 6 their changing environments. He suspected that some animals had evolved from a common ancestor. The guess was beyond traditional thoughts at that time， when people believed that all species 7 （appear） on Earth at the same time， and had not changed since. The young man brought up a 8 （complete） new idea—a theory of 9 （evolve）. He wrote a book named On the Origin of Species to explain his new theory， which immediately 10 （cause） a storm.

Even plant can run a fever， especially when they’re under attack by insects or disease. But unlike human， plants can have their temperature taken from 3，000 feet away straight up. A decade ago， adopting the infrared （紅外線） scanning technology developed for military purposes and other satellites， physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide spraying rather than rain poison on a whole field， which invariably includes plants that don’t have pest problems.

Even better， Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flying at 3，000 feet at night， an infrared scanner measured the heat emitted （散發） by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray， using 50 to 70 percent less pesticide than they otherwise would.

The bad news is that Paley’s company closed down in 1984， after only three years. Farmers resisted the new technology and long-term sponsors were hard to find. But with the renewed concern about pesticides on produce， and refinements （改進） in infrared scanning， Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States，” says George Oerther of Texas

A & M. Ray Jackson， who recently retired from the Department of Agriculture， thinks remote infrared crop scanning could be adopted by the end of the decade， but only if Paley finds the financial support which he failed to obtain 10 years ago.

1. Plants will emit an increased amount of heat when they are ________.

A. sprayed with pesticides? ? B. facing an infrared scanner

C. in poor physical condition? ? D. under too much sun rays

2. What is the purpose to use infrared scanning in applying pesticide spraying？

A. To measure the size of the affected area. B. To estimate the damage to the crops.

C. To draw a color-coded map.? ? ? D. To locate the problem area.

3. How can farmers save a considerable amount of pesticide？

A. By making use of spot-spraying. B. By transforming poisoned rain.

C. By consulting infrared scanning experts. D. By detecting crop problems at an early stage.

4. What is the agricultural experts’ attitude towards the infrared scanning technology？

A. Doubted. B. Negative. C. Concerned. D. Supportive.

Ellen Kalish runs a center for rescued wild animals in New York. When a woman asked if she could treat an owl （貓頭鷹）， she was happy to help. Then， the caller told her exactly where the tiny owl was hiding out. It was the Christmas tree in Rockefeller Center in New York City！ Kalish said she has been helping wild animals for 20 years， but she has never heard a story like that. The rescued owl has been nicknamed “Rockefeller”.

When workers were unwrapping the tree which just arrived， one of them spotted the creature. At first the worker thought the owl might be injured. One of the workers called his wife， telling her he was bringing the owl home. He asked if she could find a place that helps wildlife animals. She called Kalish.

How did Rockefeller end up stuck in the tree in the first place？ Kalish offered a few ideas. He could have gone to the tree to hide and got trapped later， she said. Maybe once the tree was loaded onto a truck， the branches squished （擠壓） him into the trunk. He might have been too scared to move.

Kalish met the woman who first called her at a gas station. The woman handed her a cardboard box with the owl inside.

Kalish brought Rockefeller back to the wildlife center. She said she gave him plenty of water and left two mice in the plastic pet carrier. They were gone by the next morning. Rockefeller spent most of his time at the wildlife center eating or sleeping. On Monday， he went to the vet （獸醫） to get some X-rays taken. He has no broken bones， Kalish added.

Rockefeller will not spend much time at the center， she said. She is preparing to release him soon. The release will be quick and quiet， she said， and she will bring a camera to take pictures of him flying away.

“I will wish him a very long and happy life，” Kalish said.

A. Disappointed. B. Exhausted. C. Surprised. D. Excited.

A. To hide there. B. To get some food.

3. How did Kalish help the owl？

A. She rescued him from other wild animals. B. She drove him back to his home.

C. She gave him water and food. D. She treated his broken bones.

People were able to examine the animals， which range from tiny insects that lived millions of years ago to the bones of dinosaurs and butterflies in amazing detail.

The scientific specimens （標本） are all either stored in alcohol or made in a fossil （化石） form and have been given to the new Darwin Centre by scientists and researchers over the last hundred years.

The centre， named after the world-famous scientist Charles Darwin， will be open free to the public. It is part of the much larger Natural History Museum， which attracts over 2 million visitors a year. The new museum has actual specimens caught by Darwin， including a parrotfish and a pipefish he caught while on his journey around the world. There are also lots of other specimens caught by famous explorers that lived over 150 years ago， which include a tusk （長牙） from an African elephant given by famous British scientist David Livingstone.

People can view specimens close up， watch videos of scientists at work， look at information on computers， and look up through the seven-floor storage hall to sense the huge scale of what’s inside. They are also able to take guided tours and join in live events with scientists.

5. What does the museum mean for visitors according to Paragraph 1？
