Spring is arriving earlier in cities. Why is this? A recent study proposed a culprit (元凶) : light pollution, a key【C1】________between a city center and the surrounding area. To test if this could cause【C2】________blooms, researchers exposed plants to long periods of artificial light and found that, as predicted, exposed plants started blooming earlier than those that grew in【C3】________light.
Unsurprisingly, plants are【C4】________assessing the available daylight to understand if it’s time for them to bloom. When the days become long enough, they know to start making leaves. But city lights make it harder for plants to assess when spring has actually sprung. Heavy exposure seems to trick plants into【C5】________it’s later in the year and that conditions are better than they actually are.
Whatever the reason, or combination of reasons, when plants bloom earlier than usual, it can spell disaster for ecological systems—in which【C6】________is key. Take for example, the relationship between oak trees and winter moths. When the moths hatch each spring, the larvae (幼虫) feed on the oak leaves. If they hatch too early, there’s no food. If they hatch too late, the【C7】________leaves are too hard for the larvae to eat. Then, if the larvae die, the things that feed on moths die, like bats. Fewer bats mean mosquitoes can【C8】________, having lost one of their major predators (捕食者). More mosquitoes can mean more vectors for disease and more chances of human exposure.
Unlike climate change, however, light pollution is a problem with readily apparent【C9】________ One report from Italy suggests using fixtures that cast light downward instead of upward and outward, or switching to high-efficiency bulbs that emit narrower wavelengths of light, which researchers have found don’t【C10】________plants quite so strongly.
A) affect E) instantly I) prosperous M) thinking
B) constantly F) mature J) rarely N) thrive
C) difference G) normal K) regard O) timing
D) early H) numerous L) solutions

选项
答案
G
解析
形容词辨义题。空格所在的句子主干完整,因此空格处应填入一个对空格前后的某处内容进行修饰的词汇。空格前为介词,空格后为名词,可知空格处应填入一个形容词用来修饰light。由该段文意可知,科学家将两种光照下的植物花期进行对比,一种是人造灯光,相应地,另一种理应是正常的日光,normal符合此处语境,故选G。
