选项
A、contribute
B、compare
C、strength
D、be drown
答案
A
解析
contribute to有助于,促成;contribute一词后常跟介词to,表示对某方面作贡献。compare后可接to或with,表达略有不同,compare to把……比作……,例:The poet compares the woman to rose,诗人把女人比作玫瑰。compare with"……与……相比,例:If you compare me with my brother,you…如果你把我同我哥相比的话。be drawn to (sth.)为……吸引,喜欢。本文中的本句可看作为主题句,“很多原因可致使衰老”,后面具体叙说,因此,由后面文章内容可推断本空应选择A。
