【答案】

（1）B

（2）A

（3）D

（4）C

【解析】【分析】本文是一篇说明文，介绍了“可折叠手机的时代即将到来。

”

（1）考查主旨大意。

根据第一段中的“Wouldn'titbegreatiftherewereaphonewiththepowersofatabletthatcouldbefoldedupandfitneatlyintothehand?

”如果有一款具有平板电脑功能的手机，可以折叠起来，整齐地放在手里，那不是很棒吗?

；以及第二段中的“Nowsomethinglikeatablet-shapedbutfoldablephoneisabouttobecomeavailable.”现在，类似于平板形状的可折叠手机即将问世。

可知本文主题是“可折叠手机的时代即将到来。

故选B。

（2）考查推理判断。

根据第五段中的“JustinDenison,calledthefoldablescreen‘thefoundationforthesmartphoneoftomorrow’.‘It'sablankcanvas（画布）forustodosomethingbeautifultogether.’”JustinDenison称可折叠屏幕是“未来智能手机的基础”。

“这是一块空白的画布，我们可以一起做一些美好的事情。

”“可知，我们能从贾斯汀·丹尼森的话中了解到“可折叠屏幕”具有很大的潜力。

”故选A。

（3）考查细节理解。

根据倒数第二段中的“However,atpresentthesefoldabledevicesareexpensive.Forexample,thepriceofHuaweiMateXis17,500RMB.That'sapricethatfewpeoplewillbeabletoafford.”然而，目前这些可折叠设备价格昂贵。

例如华为MateX的价格是17500元人民币。

这是一个很少有人能负担得起的价格。

可知，目前可折叠手机大多数家庭都买不起。

故选D。

（4）考查推理判断。

根据最后一段中的“Butifthefoldabledeviceisn'tgoingtochangetheworldovernight,thereisnodoubtthatitiscoming.”但如果这种可折叠设备不能在一夜之间改变世界，那么毫无疑问，它将会到来。

可知，作者对可折叠屏幕的未来持的态度是积极的。

故选C。

【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科普类阅读，考生需要准确捕捉细节信息，同时根据上下文进行逻辑推理，概括归纳，从而选出正确答案。
