The problem has become an【C3】________: more than 3.5 million skin cancers in over 2 million people diagnosed annually in the U.S.
    【C4】________our sun-worshipping ways, scientists and the skin-care industry are working hard to【C5】________out the safest way to tan. A handful of wearable products have【C6】________made it to market that alert wearers of UV radiation【C7】________—they tell you you’re about to【C8】________before you can see it.

【C10】

选项 A、out
B、over
C、off
D、from

答案C

解析 空格处应该填入一个副词,与start构成词组。如上题解析,本段细节句里的start,first,when等词表现的是时间上的先后关系,因此所选词要与start构成时间关系词组。故选C项,start off“开始”。A项out和B项over代入空格分别表示“出发”和“重新开始”,句意不通顺;D项from代入后表示“从……开始”,后边再接一个as,就多余了,也排除。
