1、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight orshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science forwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly ______ to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fortheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】
A.impossible
B.interesting
C.reasonable
D.necessary
正确答案:A
答案解析:本题有一定难度,考查词义辨析,干扰项有一定的干扰。根据上下文逻辑,文章此处是说“我们从课本上学到不可能有低于绝对温度的温度出现”,答案是A。

3、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers £270 million. Failure to prove that it had no part in collusion with other supermarkets and dairy processors may land it with a fine of at least £80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury\'s and the former Safeway, plus the dairy companies Wiseman, Dairy Crest and Cheese Company, had admitted being in a cartel to fix prices formilk, butter and cheese. They were fined a total of just over £116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company orindividual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politicians and farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be £11.25 over 2002 and 2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter and 15p on a half pound of cheese. There is no direct recompense forconsumers, however, and the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names and that people would become sceptical of their claims. Farmers forAction, thegroupof farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim forcompensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons and the dairygroupLactalis McLelland, and any legal action is expected to be delayed until that is completed. Tesco was defiant and said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independently and we did not collude with anyone. Our position is different from our competitors and we are defending our own case vigorously. Our philosophy is to give a good deal to customers."Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman forLactalis McLelland said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury\'s admitted yesterday that it had agreed to pay £26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised foractions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines and also said that its intention had been to help farmers under severe financial pressure.From the first paragraph, we may infer that ______.【单选题】
A.Tesco has cost consumers £270 million
B.Tesco has colluded with Asda, Wiseman, Dairy Crest and Cheese Company in fixing the dairy price
C.Tesco will be offered a leniency deal of 80 million
D.Tesco is trying its best to prove its innocence of the scandal
正确答案:D
答案解析:推理题。第一段主要讲述了Tesco公司已被卷入和其他公司联手划定牛奶价格的丑闻中,目前正在通过法律手段证明自己与此无关。因此选项D,Tesco正在竭力证明自己和丑闻无关,符合题意,故正确答案为D。

5、The Threat to KiribatiThe people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind norrain. "This never happened before," say the older citizens of Kiribati.What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth\'s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps.If the trend continues, scientists say, many countries will suffer, Bangladesh, forexample, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone\'s loss. Coral formations are home to more species than any other place on earth.The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don\'t have the money forexpensive technological solutions like seawalls. and they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.The people of Kiribati worry that one day their country will be taken away by a sudden high tide.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:A
答案解析:题干大意:基里巴斯人民担心也许有一天他们的国家会被一个突然的高潮卷走。文章开头首句提到:The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. 基里巴斯人民担心在不久的将来一天,他们的国家就会从地上消失。今年有几次,太平洋岛国已经遭到突然的高潮冲淹。题干所述与文章信息一致,故答案选A。
