(1)观点态度题。根据第二段Elizabeth Esparaz,an ophthalmologist (眼科专家) based in Cleveland,Ohio,says the science that manufacturers share as they promote these glasses can be confusing. (总部位于俄亥俄州克利夫兰市的眼科医生伊丽莎白•埃斯帕拉兹说,制造商在推广这些眼镜时所分享的科学知识可能会让人感到困惑)可推知,商家宣传的理论是受到质疑的。A.Unclear.不清楚的;B.Dismissive.不屑一顾的;C.Approving.同意的;D.Doubtful.怀疑的。故选D。
(2)推理判断题。根据第二段"The sun emits a much higher intensity of blue light than human﹣made devices,of course,and it's actually beneficial," says Dr.Esparaz ("当然,太阳发出的蓝光强度比人造设备要强得多,而且它实际上是有益的," 埃斯帕拉兹博士说)可推知,太阳散发出的蓝光是有益的。A.It can be beneficial.这可能是有益的;B.It may facilitate sleep.它可能有助于睡眠;C.It actually causes health issues.它实际上会引起健康问题;D.It merely comes from digital devices.它仅仅来自数字设备。故选A。

(4)标题归纳题。根据第一段The sales pitches tempt:Blue﹣light﹣blocking glasses are supposed to protect eyes from the effects of short﹣wavelength light emitting from our smartphones,computer screens and LED lights.Given how much time we spend on our devices,this sounds like a smart investment,right?After all,eye strain is a real issue and can lead to poor sleep and even eye diseases.The glasses can cost $15 all the way up to several hundred dollars.But do they work?(销售宣传很诱人:防蓝光眼镜应该可以保护眼睛免受智能手机、电脑屏幕和LED灯发出的短波光的影响。考虑到我们在设备上花费的时间,这听起来是一项明智的投资,对吧?毕竟,眼睛疲劳是一个真正的问题,它会导致睡眠不佳甚至眼疾。这种眼镜的价格从15美元到几百美元不等。但它们真的有效吗?)结合文章通过提出问题﹣分析问题﹣提出解决方案的方式解答了蓝光眼镜是否能够起作用,并给出具体应对措施。由此可知,文章谈论了蓝光眼镜好坏的问题,B.Blue﹣light﹣blocking Glasses:Good or Bad"防蓝光眼镜:好还是坏"最符合文章标题。故选B。
