题目内容
【题目】 If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found. 【1】 In fact, The University of Arizona found back in2012 that cell phones carry 10 times more bacteria than a toilet seat, largely because toilet seats are typically cleaned more frequently while personal electronics are largely overlooked.
As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces. 【2】
But cleaning your phone can be tricky, considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe. 【3】 These phones have a coating on then to prevent oil or grease from your hand from sticking on the phone. Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it. 【4】
That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 【5】 If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.
A.Avoid using alcohol.
B.But in doing so, you risk damaging your devices screen.
C.That means keeping your phone clean is important as well.
D.You should still be cautious when exposing them to liquids.
E.Instead use a micro fiber cloth and dampen it lightly with soap and water.
F.And each time you do, your mobile device picks up more bacteria from your hands.
G.Both companies say wiping your phone down with a soft cloth is the best way to clean it.

【解析】
本文为说明文。文章叙述了手机上的细菌含量很高,但清洁手机要注意方法。
【1】考查对上下文的理解及推理判断能力。根据前文“If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found”,以及下文“cell phones carry 10 times more bacteria than a toilet seat”如果你和普通美国人一样,你可能会象2018年的一项研究发现的那样,每天查看智能手机的次数可能会超过50次,手机携带的细菌是马桶座圈的10倍。可知,每次这样做,你的移动设备从你的手上收集更多的细菌。分析选项可知F项And each time you do, your mobile device picks up more bacteria from your hands(每次你这样做,你的移动设备从你的手上收集更多的细菌)符合题意,故选F。
【2】考查对上下文的理解及推理判断能力。根据上文“As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces.”随着新型冠状病毒继续蔓延,美国疾病控制和预防中心和世界卫生组织建议公众经常洗手,对经常接触的物体和表面进行消毒。可知,保持手机清洁也很重要。分析选项可知C项That means keeping your phone clean is important as well(这意味着保持手机清洁也很重要)符合题意,故选C。
【3】考查对上下文的理解及推理判断能力。根据上文“considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe.” 考虑到许多你通常用来消毒的标准化清洁产品可能会损坏你的移动设备。你可能想用酒精或消毒剂擦拭一下手机屏幕。由此可知,如果用酒精或消毒剂给手机消毒的话会伤害手机屏幕。以及下文“Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it.” 直接用酒精或那些日常解决方案在手机上、在杯子上使用会对身体造成伤害。可知,这样会损坏你的设备屏幕。分析选项可知B项 But in doing so, you risk damaging your devices screen(但这样做,你就有可能损坏你的设备屏幕)符合题意,故选B。
【4】考查对上下文的理解及推理判断能力。根据上文“Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it.” 直接在手机上使用酒精或其他类似的日常解决方案会对手机造成伤害。所以要用超细纤维布,并用肥皂和水轻轻地润湿。分析选项可知E项Instead use a micro fiber cloth and dampen it lightly with soap and water(取而代之的是使用一块微纤维布,用肥皂和水轻轻地将其浸湿)符合题意,故选E。
【5】考查对上下文的理解及推理判断能力。根据上文“That lines up with the advice Apple and Samsung offer which warn not to use cleaning products.” 这与苹果和三星提出的警告不要使用清洁产品的建议一致。以及下文“If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.”如果需要给你的智能手机消毒,考虑使用紫外线来杀死细菌。分析选项可知G项Both companies say wiping your phone down with a soft cloth is the best way to clean it(两家公司都说用软布擦拭手机是最好的清洁方法)符合题意,且G项中Both companies与文中所提的“Apple and Samsung”两家公司是一致的,故选G。
