the professor was so busy that he culd hardly find any time to __ to his health and personal affais.
a.spare
b.devote
c.spend
d.cost
why?

Answer 1

b.这句话的意思：教授如此忙以至于没有时间用于自己的健康和私人事情。
spare抽出，匀出后接双宾语，如：Can you spare me this book for a while? 这本书你能让我看一会儿吗？

spend后接on sth ;cost“花费”的意思在这里不合适。
devote to 把...献给; 把...专用于
He has devoted his whole life to benefiting mankind.
他为全人类的利益献出了自己的一生
所以应选b
