故选C项。
3.A [空格前第二句中出现charactertypes与A选项中的character相对应;
空格前一句中的you与选项中的your在人称上保持一致,空格前一句中动词love与hate和A选项中的dependson保持对应,故选A项。
4.E [空格前一句出现了teenageryears与E选项当中的this相对,另外E选项当中提到moveawayfromfamilyintothebiggerworld也是对空格前一句中的teenageryears的解释。
故选E项。
5.G [空格后一句中提及pleasure和fear,是从正反两方面进行对比,对应G项中的differently,再根据空格后一句中出现的risk-seeker,brain,us等词与选项G中的nervoussituation,ourbrains相对应,故选G项。
