Q27
Daffodils are likely to flower early in response to................weather.
分析
题干中可以划定位词的有daffodils和weather。空格前面是in response to【对...做出的回应】，后边是weather，所以空格应该写名词或形容词，用来修饰weather。这几道题是最后几道题，所以我们可以从最后一段往前定位。
定位
GSome plants mainly use day length as an indicator of the season. Other species, such as daffodils, have considerable temperature sensitivity, and can flower months in advance during a warm winter. In fact, the discovery of the dual role of phytochromes provides the science behind a well-known rhyme long used to predict the coming season: oak before ash we’ll have a splash, ash before oak we’re in for a soak.
答案
上文第二句出现了daffodils， 后半句中的flower对应题干中的flower， 这句中的in advance对应题干中的early,所以可以确定答案在这句中。所以这句中的winter 对应题干中的weather, 所以前面的warm是答案。
Q28
If ash trees come into leaf before oak trees, the weather in ................ will probably be wet.
分析
题干中可以划定位词的有ash trees, leaf, oak trees, 这句中的关键词wet 在原文中要有对应的内容。空格前面是weather in，所以空格填写名词，可能是一种环境，也有可能是一段时期。
定位
G... Wigge explains: ‘Oak trees rely much more on temperature, likely using phytochromes as thermometers to dictate development, whereas ash trees rely on measuring day length to determine their seasonal timing. A warmer spring, and consequently a higher likeliness of a hot summer, will result in oak leafing before ash. A cold spring will see the opposite. As the British know only too well, a colder summer is likely to be a rain-soaked one.’
答案
上文第二句出现了oak leafing before ash。题干中说的是ash trees come into leaf before oak trees,所以应该对应下一句A cold spring will see the opposite。最后一句中的rain-soaked【泡在雨里的】对应题干中的wet，最后一句的rain-soaked one指的是这句的主语summer，所以答案是summer，符合我们的推测，表示一个时间段。
Q29
The research was carried out using a particular species of ................
分析
题干中可以划定位词的有research和species of,空格前面是species of，所以后边应该写表示动物或植物的名词。
定位
HThe new findings are the culmination of twelve years of research involving scientists from Germany, Argentina and the US, as well as the Cambridge team. The work was done in a model system, using a mustard plant called Arabidopsis, but Wigge says
the phytochrome genes necessary for temperature sensing are found in crop plants as well...
答案
上文第 一句出现了research, 后半句中出现了using,所以答案是mustard plant。这个答案符合我们的推测，是一种植物。注意，题干中没有跟原文中的called对应的词，所以不要把Arabidopsis写成答案。
