Ⅰ.1.B [根据生活常识可知，不少人会在乘地铁、汽车、火车时打盹休息。除了“睡觉”的乘客外，其他几乎都在玩手机。]
2．A [由于地铁的性质(在地铁上就像在公交车上一样，人挨人地坐着)，不难看“清楚”别人在干什么。]
3．D [根据常识可知，地铁是修建在城市“地下的”，故信号不好。]
4．B [地铁里信号不好，这使得发信息或上网不太可能，但还是有很多事情可以使用手机做的。前后为转折关系。]
5．C [使用手机打牌属于play games，显然games可以包括cards以及很多类似的活动。第二段第三句“All I could do on this phone was to send ______，make calls and play one game.”中的game也是提示信息。]
6．D [此处指人们只要从地铁站一“出来”就会开始发短信、打电话或查收他们的邮件。]
7．B [只要手中有一部手机，你就可以保持与世界上每个人持续不断的“联系”。]
8．B [参见上题解析。as long as只要。]
9．C [根据此空前的“my smartphone broke”及最后一段首句中的“as soon as I got my smartphone back I would be one of those people once again”可知，作者的智能手机坏了，需要维修。send off送去，寄出。故选C。]
10．C [参见上题解析。repair修理，维修。]
11．D [根据上句可知，作者的智能手机坏了，返修需要一周左右的时间。这期间，作者只好用原来的“旧”手机与家人朋友保持联系。故选D。]
12．B [旧手机只能发“信息”、接打电话和玩一个游戏。send messages发送信息，故选B。]
13．C [不能上网，就无法持续不断地“更新”有关朋友或名人的动态。接下来的“the latest”是提示信息。故选C。]
14．D [不能上网，自然就没有以前那么累，休息得好，体力精力“恢复得好”，精神焕发。故选D。]
15．C [手机不能上网，作者就可以多花些时间来欣赏周围的风景。此处take in my surroundings意为“欣赏周围的风景”。]
16．B [此处指作者可以更多地“享受”在伦敦的时间。]
17．A [上段主要讲述作者智能手机坏了之后，使用旧手机不能上网，反而获得了难得的清静。本段笔锋转到如果智能手机修好了，自己就会又回到以前泡在网上的状态。本段与上段为转折关系，故选A。]
18．C [以前，智能手机能够上网，作者“迷恋于”上网获得每个人的动向、玩游戏或上社交网站等。be addicted to沉溺于……，故选C。]
19．D [参见上题解析。waste time (in) doing sth.浪费时间做某事。]
20．B [对比智能手机和旧手机的利与弊，作者倾向于选择旧手机，保持一份远离网络的清静。根据前半句中的“go back to using the basic phone”可知，作者决定“忘记”自己已拿回智能手机……。]
