　　Q27

　　The Cambridge scientists’discovery of the ‘thermometer molecule’caused surprise among other scientists.

　　分析

　　题干中可以划定位词的有The Cambridge scientists’discovery, thermometer molecule’。这道题考察是非考点，即是否导致surprise。

　　定位

　　A  An international team of scientists led by the University of Cambridge has discovered that the ‘thermometer’molecule in plants enables them to develop according to seasonal temperature changes. Researchers have revealed that molecules called phytochromes - used by plants to detect light during the day - actually change their function in darkness to become cellular temperature gauges that measure the heat of the night. The new findings, published in the journal Science, show that phytochromes control genetic switches in response to temperature as well as light to dictate plant development.

　　答案

　　上文第 一句出现了定位词scientists led by the University of Cambridge和thermometer’molecule。第二句中的researchers还是指第  一句的这些scientist， 第三句中的the new findings指代第 一句的thermometer’molecule。但这段没有提到other scientists 和surprise，接着往下看。

　　定位

　　BAt night, these molecules change states, and the pace at which they change is ‘directly proportional to temperature’, say scientists, who compare phytochromes to mercury in a thermometer. The warmer it is, the faster the molecular change - stimulating plant growth.

　　答案

　　这段第 一句说的是molecules的工作原理，这段中的scientists还是第 一段的scientists。

　　CFarmers and gardeners have known for hundreds of years how responsive plants are to temperature: warm winters cause many trees and flowers to bud early, something humans have long used to predict weather and harvest times for the coming year. The latest research pinpoints for the first time a molecular mechanism in plants that reacts to temperature - often triggering the buds of spring we long to see at the end of winter.

　　上文第 一句说了farmers and gardeners ，所以可以确定文章没有提到other scientists 和surprise，所以这道题答案是NOT GIVEN。

　　为了节省时间，我建议大家一次找两道判断题，当你看到第二题的定位的时候，如果第 一题的内容还没有完整出现，那么第 一题就可以确定NOT GIVEN了。

　　Q28

　　The target for agricultural production by 2050 could be missed.

　　分析

　　题干中可以划定位词的有agricultural production by 2050， 这道题考察是非题，即是否missed。

　　定位

　　DWith weather and temperatures set to become ever more unpredictable due to climate change, researchers say the discovery that this light-sensing molecule also functions as the internal thermometer in plant cells could help us breed tougher crops. ‘It is estimated that agricultural yields will need to double by 2050, but climate change is a major threat to achieving this. Key crops such as wheat and rice are sensitive to high temperatures. Thermal stress reduces crop yields by around 10% for every one degree increase in temperature,’says lead researcher Dr Philip Wigge from Cambridge’s Sainsbury Laboratory. ‘Discovering the molecules that allow plants to sense temperature has the potential to accelerate the breeding of crops resilient to thermal stress and climate change.’

　　答案

　　上文第二句出现了agricultural yields对应题干中agricultural production， by 2050原词重现，第二句中的will need to double【将需要翻一番】对应题干中的target，后半句中的climate change is a major threat to achieve this【气候变化是达成这个（目标）的重大威胁】可以对应题干中的could be missed【不能达标】。所以原文题干的内容一致，答案是TRUE。从这道题可以看出，threat可以当成否定词用。

　　Q29

　　Wheat and rice suffer from a rise in temperatures.

　　分析

　　题干中可以划定位词的有wheat and rice和rise in temperatures。这道题考察是非考点，即到底会不会suffer from【遭受...】。

　　定位

　　DWith weather and temperatures set to become ever more unpredictable due to climate change, researchers say the discovery that this light-sensing molecule also functions as the internal thermometer in plant cells could help us breed tougher crops. ‘It is estimated that agricultural yields will need to double by 2050, but climate change is a major threat to achieving this. Key crops such as wheat and rice are sensitive to high temperatures. Thermal stress reduces crop yields by around 10% for every one degree increase in temperature,’says lead researcher Dr Philip Wigge from Cambridge’s Sainsbury Laboratory. ‘Discovering the molecules that allow plants to sense temperature has the potential to accelerate the breeding of crops resilient to thermal stress and climate change.’

　　答案

　　上一道题对应的下一句就是这道题的定位。上文第三句中出现了定位词Key crops such as wheat and rice， 这句中的high temperatures对应题干中的rise in temperatures，但原文中的sensitive to 【对...敏感】跟suffer from 不能划等号，需要看下一句。下一句中的thermal stress【热压力，thermal热的，热能的这个词一定要背的）】指代上一句的high temperatures，这句中的reduces crop yields by around 10%【降低粮食产量约10%】可以对应题干中的suffer from，所以这道题答案是TRUE.

　　Q30

　　It may be possible to develop crops that require less water.

　　分析

　　题干中可以划定位词的有water。这道题考察是非考点，即是否possible。

　　定位

　　DWith weather and temperatures set to become ever more unpredictable due to climate change, researchers say the discovery that this light-sensing molecule also functions as the internal thermometer in plant cells could help us breed tougher crops. ‘It is estimated that agricultural yields will need to double by 2050, but climate change is a major threat to achieving this. Key crops such as wheat and rice are sensitive to high temperatures. Thermal stress reduces crop yields by around 10% for every one degree increase in temperature,’says lead researcher Dr Philip Wigge from Cambridge’s Sainsbury Laboratory. ‘Discovering the molecules that allow plants to sense temperature has the potential to accelerate the breeding of crops resilient to thermal stress and climate change.’

　　答案

　　上文最后一句中的breeding of crops【培养庄稼】对应题干中的develop crops，最后一句中的has the potential【有潜力】对应题干中的it may possible，但这句中的crops resilient to thermal stress and climate change与题干中的require less water没有必然联系，热与水可以并存，不是矛盾的，所以答案是NOT GIVEN。

　　Q31

　　Plants grow faster in sunlight than in shade.

　　分析

　　题干中可以划定位词的有sunlight 和shade。这道题考察比较考点，即sunlight 和shade 关于生长速度的影响，前者大于后者。

　　定位

　　EIn their active state, phytochrome molecules bind themselves to DNA to restrict plant growth. During the day, sunlight activates the molecules, slowing down growth. If a plant finds itself in shade, phytochromes are quickly inactivated - enabling it to grow faster to find sunlight again. This is how plants compete to escape each other’s shade. ‘Light-driven changes to phytochrome activity occur very fast, in less than a second,’says Wigge. At night, however, it’s a different story. Instead of a rapid deactivation following sundown, the molecules gradually change from their active to inactive state. This is called ‘dark reversion’. ‘Just as mercury rises in a thermometer, the rate at which phytochromes revert to their inactive state during the night is a direct measure of temperature,’says Wigge.

　　答案

　　上文第二句出现了sunlight activates the molecules, slowing down growth。第三句出现了If a plant finds itself in shade, phytochromes are quickly inactivated - enabling it to grow faster to find sunlight again，结合这两句可以看出sunlight的growth比shade要慢，所以原文与题干的内容相反，答案是FALSE。所以做判断题不能靠直觉（可能是错觉）也不能靠常识（可能是误解），要根据原文的信息进行判断。

　　Q32

　　Phytochromes change their state at the same speed day and night.

　　分析

　　题干中可以划定位词的有Phytochromes和speed。这道题考察是非考点，即day 和night的speed是一样的。

　　定位

　　EIn their active state, phytochrome molecules bind themselves to DNA to restrict plant growth. During the day, sunlight activates the molecules, slowing down growth. If a plant finds itself in shade, phytochromes are quickly inactivated - enabling it to grow faster to find sunlight again. This is how plants compete to escape each other’s shade. ‘Light-driven changes to phytochrome activity occur very fast, in less than a second,’says Wigge. At night, however, it’s a different story. Instead of a rapid deactivation following sundown, the molecules gradually change from their active to inactive state. This is called ‘dark reversion’. ‘Just as mercury rises in a thermometer, the rate at which phytochromes revert to their inactive state during the night is a direct measure of temperature,’says Wigge.

　　答案

　　上文第五句出现了changes to phytochrome， 这句中的occur very fast对应题干中的speed。第六句中的night 和however，告诉我们这两者是不一样的，具体要看下一句。第七句中的the molecules gradually change【逐渐变化】可以对应题干中的speed。所以speed of day>speed night，所以与题干中的same是矛盾的，答案是FALSE。
