Half of your brain stays alert and prepared for danger when you sleep in a new place, a study has revealed. This phenomenon is often【C1】______ to as the "first-night-effect". Researchers from Brown University found that a network in the left hemisphere of the brain "remained more active" than the network in the right side of the brain. Playing sounds into the right ears (stimulating the left hemisphere) of【C2】______ was more likely to wake them up than if the noises were played into their left ears.
It was【C3】______ observed that the left side of the brain was more active during deep sleep. When the researchers repeated the laboratory experiment on the second and third nights they found the left hemisphere could not be stimulated in the same way during deep sleep. The researchers explained that the study demonstrated when we are in a【C4】______ environment the brain partly remains alert so that humans can defend themselves against any【C5】______ danger.
The researchers believe this is the first time that the "first-night-effect" of different brain states has been【C6】______ in humans. It isn’t, however, the first time it has ever been seen. Some animal【C7】______ also display this phenomenon. For example, dolphins, as well as other【C8】______ animals, shut down one hemisphere of the brain when they go to sleep. A previous study noted that dolphins always【C9】______ control their breathing. Without keeping the brain active while sleeping, they would probably down. But, as the human study suggests, another reason for dolphins keeping their eyes open during sleep is that they can look out for【C10】______ while asleep. It also keeps their physiological processes working.
A) classified I) potential
B) consciously J) predators
C) dramatically K) referred
D) exotic L) species
E) identified M) specifically
F) inherent N) varieties
G) marine O) volunteers H) novel
【C4】
选项
答案
H
解析
空格前为不定冠词a,空格后为名词environment,故本空需要填入一个以辅音音素开头的形容词。文章开头就提到“当人们在一个新的地方睡觉时,有一半的大脑处于警惕状态”,而且本句也提到“大脑在一定程度上处于警惕状态”,由此可知,这里指的是“当我们身处一个陌生的或新的环境时”。备选项中只有novel(新的,新颖的)符合文义,故答案为H。
