16、nically and conventionally (常规地) grown onions, carrots, and potatoes. The study only looked at three types of vegetables and just a few select nutrients. But the experiment was part of a bigger project that was so systematic and strictly controlled that the findings likely apply to other crops, too.
17、 “Giving preference to organic products because they contain more bioactive components is doubtful and not supported by scientific evidence,” Knuthsen said. “Still, there are many good reasons for the consumer to select organic food products, including absence of pesticide residues (农药残留) in foods,
18、animal welfare, and environmental protections.”Argument over whether organic produce is more nutritious than conventional varieties has been around for at least a decade, said Jeffrey Blumberg, director of the Antioxidants Research Laboratory at Tufts University in Boston. “Some studies have suggest
19、ed that organically grown plants contain higher levels of healthful antioxidants, possibly because some antioxidants act as natural fungicides (杀真菌剂), pesticides and insecticides,” he said. “The idea is that, without help from industrial chemicals, plants on organic farms need to work harder to prot
20、ect themselves. They end up becoming more nutritious as a result.” But plenty of other studies have shown no such relationship. “I understand that organic farmers would love to be able to say that theirs are super-fruits and super-vegetables because there are higher amounts of these compounds in the
21、m,” Blumberg said. “If you want to buy them because you think theyre safer for the planet to grow things that way, or because you think pesticides are bad for you or your family, or you like that they come from a shorter distance away, thats great.”“But if you want to buy them because theyre more nu
22、tritious, youre confused, and we dont know if thats true or not.”1. The new study proves that. A. there are plenty of good reasons to buy organic produceB. nutrition is one of the good reasons to buy organic produceC. some organically and conventionally grown foods have the same antioxidant levelsD.
23、 organic produce is harmful to our health2. Why do people prefer organic products? A. Because they think organic products have no bioactive components. B. Because scientific evidence supports organic products can make them stronger. C. Because its proved that organic produce is more nutritious than
24、conventional varieties. D. Because they think organic food products have no harmful things. 3. The fourth paragraph mainly tells us. A. its unclear whether organic produce is more nutritious than conventional varietiesB. organically grown plants contain higher levels of healthful antioxidantsC. plan
25、ts on organic farms need to work harder to protect themselvesD. plenty of other studies have shown no such relationship 4. Which is NOT the reason for you to buy organic products according to Blumberg? A. There are higher amounts of these compounds in them. B. Theyre safer for the planet to grow thi
26、ngs that way. C. Pesticides are bad for you or your family. D. They are more nutritious. 【参考答案】14、CDAD阅读理解【2012四川卷】Plants are flowering faster than scientists predicted(预测)in reaction to climate change, which could have long damaging effects on food chains and ecosystems.Global warming is having a g

37、述了全球变暖的气候环境会让植物提前开花，进而影响整个食物链及生态系统。57. B细节理解题。第一段话给读者传达的主要信息存在于主句，而不是which所引导的定语从句上。根据“Plants are flowering faster than scientists predicted”可知，作者是要告知读者植物开花的增速超出了科学家的预期。故选B。A为次要信息。58. C推理判断题。第五段话“It found that some experiments had underestimated(低估)the speed of flowering by 8.5 times and leafing by
38、4 times.”暗示读者：对于植物所设计的实验应该有所改进，故答案选C。59. B细节理解题。根据第四段“They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.”可知植物对气候变化的反应对整个食物链和生态系统都至关重要。故答案选B。60. D推理判断题。从倒数第二段“has risen by about 0.8 since 1900, and nea
39、rly 0.2 every ten years since 1979.”可知A、C项错误；从最后一段叙述可知，如果本世纪地球变暖超过2，便会出现weather extremes。暗示我们这个世纪地球温度的上升需要控制在2的范围之内。故答案选D。阅读理解【2012山东卷】For those who are tired of doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(applica
