When children hit puberty(青春期), their ability to learn a second language drops. They find it harder to learn their way around a new location. Why is this? Sheryl Smith and her【C1】______at the State University of New York now【C2】______that all of these behavioural changes could be due to a temporary increase in a chemical receptor that inhibits brain activity in an area responsible for learning.
In 2007, Smith’s team discovered that the number of these receptors【C3】______in mice when they hit puberty, before falling back in adulthood. In their latest study, Smith’s team set about finding out if these receptor change in mice might lead to impaired learning abilities,【C4】______like those seen in pubescent humans.
The group【C5】______the hippocampus(海马体)in mouse brains. Sure enough, pubertal mice had seven times as many of the receptors as infant mice. In adulthood, the number of these receptors fell back to an intermediate level.
Smith reckons that the same mechanism might underlie the learning deficits teenagers experience. Cheryl Sisk at Michigan State University at East Lansing agrees that "mouse puberty is【C6】______to human puberty, although the timescale is different".
In a further experiment, Smith found that she could remove the learning deficit by【C7】______pubertal mice with THP.
Smith suggests that in her most recent experiment, giving extra THP to pubertal mice increased their brain activity and that this activity may have【C8】______for their learning deficits.
Smith suggests that a【C9】______form of THP could be developed for teenagers with learning difficulties, although she acknowledges that【C10】______would need to be taken not to create any new problems.
A)activity F)even K)reckon
B)adopt G)examined L)research
C)care H)familiar M)similar
D)colleagues I)injecting N)soared
E)compensated J)rather O)synthetic [br] 【C3】

解析
动词辨析题。由句子结构可知,空格处应填动词作谓语,再根据空格所在句的时态可知,空格处应填动词过去式。由句意可知,本句是把老鼠青春期和成年的受体数量作比较。根据首段中的a temporary increase和空格后面的falling back in adulthood以及备选项可知,soared“猛增,骤升”符合句意。
