   Everyone knows that too much time in the sun can expose you to 【C1】______ ultraviolet radiation, which can lead to skin cancers. But that’s not going to stop people from cooking themselves in 【C2】______ of the perfect tan. The problem has become an 【C3】______: more than 2 million skin cancers in over 3.5 million people diagnosed annually in the U.S.
   Given our sun-worshipping ways, scientists and the skin-care industry are working hard to 【C4】______ out the safest way to tan. A handful of wearable products have recently made it to market that alert wearers of UV radiation levels—they tell you you’re about to burn before you can see it.
   The simplest might be Smartsun wristband, which alerts wearers of UV 【C5】______ with just a change of color. It starts off as yellowish-brown when first exposed to UV rays; when it turns pink, that’s the warning to seek shade and slather (厚厚地涂)on sunscreen.
   If you prefer something a little more invasive, try the UVeBand, which vibrates when you’ve had your share of UV rays. Then there’s the JUNE, developed and recently 【C6】______ by Netatmo. The JUNE has UV sensors built into a fake jewel that connect 【C7】______ to a smartphone, where an app monitors UV 【C8】______ in real time, alerting when it’s time to get out of the sun. It also  【C9】______ your radiation exposure over time, so you can see how bad your summer has been for your skin, long term.

【C3】
选项
答案D
解析 空格前为不定冠词an，空格处需填入元音开头的名词。从冒号后的内容“在美同，每年就诊的人也才350多万，但却发现有200万例皮肤癌”可知，暴晒引起皮肤癌已经非常普遍，故epidemic“流行病”符合此处的语境，故选D项。exaggeration意为“夸张”，语义不符合，可排除。
