MEGADIM, Israel (AP)-The worst forest fire in Israel's history on Thursday destroyed one of the country's few forested areas, killing at least 36 guards on their way to rescue prisoners there, destroying homes and forcing the evacuation (疏散) of thousands. The fire ran through the Carmel forest in Israel's Galilee, reaching the coastal city of Haifa, jumping from place to place in the forest. The fire broke out around midday and quickly spread and was still burning out of control as midnight approached. Investigators (调查者) supposed that the fire could have been set accidentally, or it might have been a criminal act, but pretty much ruled out (排除) some sort of attack by a Palestinian group. “This is a huge disaster,” Prime Minister Benjamin Netanyahu said. “The government is using all means to control the fire.” He said some countries such as Cyprus, Italy, Russia and Greece agreed to provide backup. Most of the dead were Prison Service guards racing through the fire toward a prison to evacuate the prisoners, most of them Palestinians. A tree fell across the road, blocking their bus. Some guards were burned alive inside, while others died as they tried to escape. Fourteen bodies were found near the burnt bus 10 hours after the fire started. The fire heavily damaged one of Israel's few large forests, made up of natural growth and planted areas, a favorite place for camping and a home for dozens of species of wildlife. Forestry workers tried to evacuate animals from the fire. The forest recovered slowly from a fire in 1989, but experts said Thursday's big fire was many times worse.
1.Some Prison Service guards died when they tried to ________.
A.control the running prisoners | B.put out the fierce forest fire |
C.get away from the burning bus | D.save the guards trapped in the fire . |
2.According to the investigators, which of the following might be the cause of the fire?
A.Prisoners set the fire purposely. | B.The fire broke out all by itself. |
C.A Palestinian group did it. | D.The fire was started by accident. |
3.We learn from the text that ________.
A.all of the dead were Prison Service guards |
B.the forest once suffered a fire in the 1980s |
C.the animals didn't suffer from the fire |
D.the fire caused 50 deaths altogether . |

Scientists at Israel's Tel Aviv University say—they have created the world’s first 3D-printed heart with human tissue and blood vessels. Although the organ is only as big as a rabbit’s heart, the researchers are hoping the technology could one day be developed enough to help human patients in need of a heart transplant.
Lead researcher Tal Dvir said that while other scientists have managed to 3D—print the structure of a heart in the past, this is the first time anyone has printed an entire heart. “Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future,”Dvir said in a press statement.
Scientists used fatty tissue taken from human patients to create the heart. Some material in the tissue was reprogrammed to become stem cells. The remaining material was processed into a hydrogel. They used the hydrogel as a printing:“ink”. This method is key to removing the risk that the implant will be rejected by the patient’s body. The team’s next step is to cultivate the organs in a lab and to teach them how to“behave”like hearts. Dvir’s 3D-printed hearts can currently contract, but the cells still need to develop a pumping ability. His team eventually plans to test the hearts in animals.
“Maybe, in ten years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely, ”Dvir said. Heart disease is the leading cause of death for both men and women, according to the Centers for Disease Control and Prevention. About 610, 000 people die of this disease in America every year—amounting to about 1 in every 4 deaths. There are currently more than 3700 people waiting for a heart transplant in the United States, according to data from the United States Department of Health and Human Services.
1.What is the purpose of creating the 3D-printed heart?
A.To develop 3D-printed technology. B.To study the hearts of rabbits.
C.To connect hospitals with universities. D.To help patients receive a new heart.
2.Why does the author mention the current situation of heart disease patients?
A.To appeal to hospitals to reduce medical fees.
B.To show the need to improve the new technology.
C.To urge researchers to develop effective medical devices.
D.To introduce the main reason for heart disease to the public.
3.What is the third paragraph mainly about?
A.The course of the research. B.The importance of the research.
C.The material of the 3D-printed heart. D.The method of the 3D-printed heart.
4.What’s Dvir’s attitude towards the new technology?
A.Disapproving. B.Doubtful.
C.Positive. D.Indifferent.

Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone(臭氧)levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
1. According to the new findings, taking steps to prevent northern forest fires may _______.
A. result in a warming climate B. cause the forest fires to occur more frequently
C. lead to a longer fire season D. protect the forests and the environment there
2. Earlier studies about northern forest fires ________.
A. analyze all aspects of how northern fires influence climate
B. indicate that forest fires will pollute the atmosphere
C. suggest that people should take measures to protect environment
D. suggest that the fires will speed up climate warming
3. The underlined phrase “soaked up” in the last paragraph most probably means ________.
A. released B. absorbed C. created D. disturbed
4. From the text we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ______.
A. warm the climate as the assumption goes
B. allow more snow to reflect more sunlight into space and thus cool the climate
C. destroy large areas of forests and pollute the far-off sea ice
D. help to gain more energy rather than release more energy

In addition,great numbers of animals were killed by the fires that burned out of control. The fires were driven by high winds,moving as many as ten miles a day.Many small animals died in the flames.The fires’rapid advances gave the wildlife little chance to escape.Even today,few of these small forest animals have returned to live in the park.

A.became out of control at first
