问题     Everyone knows that too much time in the sun can expose you to excessive ultraviolet radiation, which can lead to skin cancers.【C1】________that’s not going to stop people from cooking themselves【C2】________the perfect tan. 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.
    The simplest might be Smartsun wristband, which alerts wearers of UV overexposure with just a【C9】________of color. It starts【C10】________as yellow-ish-brown when first exposed to UV rays; when it【C11】________pink, that’s the warning to seek【C12】________and slather on sunscreen.
    If you prefer something a little more【C13】________, try the UVeBand, which vibrates when you’ve had your share of UV rays. Then there’s the JUNE, developed and recently【C14】________by Netatmo. The JUNE has UV sensors built into a fake jewel that connect wirelessly to a smartphone, where an app monitors UV【C15】________in real time, alerting when it’s time to get out of the sun. It also【C16】________your radiation exposure over time,【C17】________you can see how bad your summer has been for your skin, long term.
    All of these products are designed to help wearers【C18】________their sun time. But none have been reviewed or【C19】________by any health regulatory body, which raises some【C20】________.  
【C19】
选项 A、underlined
B、submitted
C、approved
D、revised
答案C
解析 空格处与or前的reviewed是并列关系。而该句由But引导，逻辑上表转折，即前一句说这些产品的设计目的是好的，但是没有一个经过卫生健康部门审查或_________。行政部门的工作之一就是审批，故选C项approved“批准”。A项underlined“强调”、B项submitted“提交”和D项revised“修改”这三项跟or前的reviewed语义上不相关，均可排除。
