Article: One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. "I knew it wasn't the moon", he said. "I drive this road all the time and I notice little things out of place." Duffy stopped his car and got out to examine. Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail. His car fell and rolled end over end, landing on its top more than two hundred feet below. Duffy rushed to call for help, then returned and got down to reach the injured driver. Snow covered the valley and the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the injured man in time, along with the blankets from his car. Life-saving deeds are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister ate rat poison, and Duffy cleaned out her mouth, make her drink milk to protect her stomach and called doctors. "We have tried to teach the children good values, and it looks like we have got some reward for it." His father says. Question: From the above article, we can see Duffy has saved _ at least. Yes or no, is the answer "three"?
No

Article: Dear Editor , I used to be a doctor in a children's hospital. Sometimes I treated children who had been poisoned by medicines for older family members. The children didn't know the medicine was dangerous; they just knew it tasted sweet. Children easily opened the bottle that we now use in China. Some days ago I talked about medicine with an American. He showed me a kind of plastic bottle. The design was very quite simple and I'm sure our Chinese factories could produce these bottles. The top of the bottle locks but can be opened by pressing down on it while turning. This is difficult for most young children to do, though grown-ups can open these bottles very easily. I'm certain that the price of making such tops would be very low. As a doctor, I'd love to see this done. And most parents would be grateful. Yours, Li Hua Question: The letter was written to the editor to ask for _ . Yes or no, is the answer "support from the Chinese factories"?
(Answer)
No

Ques: Article: Climatic conditions are delicately adjusted to composition of the Earth's atmosphere. If there were a change in the atmosphere -- for example, in the amounts of atmospheric gases -- the climate would probably change also. A slight increase in water vapor , for example, would increase the heat-keeping capacity of the atmosphere and would lead to a rise in global temperatures. The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth's incoming energy is short-wavelength radiation , which tends to pass through atmospheric CO2easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation , which CO2absorbs and then goes toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430~C.If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2concentration would lead only to a reduction in global temperatures of 3degC. If, because of an increase in forest fires or volcanic activity, the CO2content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relied on both the warmth and the availability of CO2, would probably increase. As a consequence, plant would use more and more CO2. Eventually CO2levels would decrease and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2would thus be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2present in the atmosphere, with regular... Question: The discussion of climate in the passage suggests that _ . Yes or no, is the answer "we are unable at present to measure global temperature changes precisely."?
Ans: No

Article: QINGDAO--Water and power supplies have been _ in the East Chinese city of Qingdao, the site of an oil pipeline explosion on Friday, the local government said on Monday. Crude oil began leaking from the pipeline at 3:00 an Friday in Qingdao in Shandong province. The valves of the Huangdao oil warehouse were shut about 15 minutes later. The oil spill then flowed into the city's rainwater pipe network, which empties into Jiaozhou Bay. Explosions occurred at two locations around 10:30 am Friday when workers were clearing the spill. According to the local government, about 85 percent of public heating and 90 percent of the gas supply were also brought back to normal as of Monday. Residents who have been taken to the temporary settlements are receiving bottled water and bread. Many schools and kindergartens have reopened classes after Friday's oil pipeline explosion. No injures and deaths of students or teachers have been reported following the explosions at an underground pipeline operated by Sinopec. The school buildings of one middle school in the district were seriously damaged during the explosions. Education authorities have arranged psychological help for students and teaching staff. All other 18 schools and kindergartens in the district reopened classes on Monday. As of Monday noon, the death toll from the explosion had risen to 55, with 9 people still missing and 136 hospitalized. According to local police, 49 bodied have been identified so far, and 42 of them were male victims. As of Monday morning, the blood supply in Qingdao was enough for the injured after more than 950 people in the city donated more than 340,000 ml of blood in the wake of the incident. Question: We can learn that by Monday noon the deaths in the explosion reached at least _ . Yes or no, is the answer "55"?
No
