Amazon today unveiled Dash Buttons, an easy way for customers to【C1】______ select bulk goods【C2】______ an internet-connected button, and yesterday【C3】______ Home Services, an on-demand installation and handyman service. Combined, they show that the e-commerce giant has a clear understanding of how the Internet-of-things will【C4】______ its business. And it isn't going to be shy about capitalizing on connectivity to build its bottom line. Dash Buttons are an adaptation of Amazon's【C5】______ -controlled Dash ordering system that lets people speak to order new【C6】______ items. So【C7】______ Amazon has is a retrofit strategy for connecting smart appliances to its e-commerce operations and a future-facing strategy for the coming flood of【C8】______ devices. And all of this is geared around making buying products from Amazon as easy as possible. The【C9】______ of one-button tasks are appealing,【C10】______ it could lead to a【C11】______ of packages ending up at people's doors if Amazon doesn't try to【C12】______ waste on its end, by grouping shipments together when possible. People on Twitter seem mostly【C13】______ about pets and small children playing with the Dash Buttons and ordering multiples of their Kraft Macaroni and Cheese boxes, although Amazon notes that【C14】______ the button is pressed more than once, the order doesn't go【C15】______ on the second time, and you'll get a smartphone notification about it. Amazon also recently launched Home Services, following up on last year's opening of a home automation e-store devoted to connected gadgets for the home—many of which require a【C16】______ installer. So now Amazon can sell these devices along with the person who can install them. It also is【C17】______ on maintenance, via a network of service providers that it can call【C18】______ for its network of suppliers or for its own planned connected home play. With Dash, it's【C19】______ an offensive play to【C20】______ up more sales as devices come online. With Amazon Home Services, it's making a defensive play as other large companies try to become more vertically integrated.
【答案解析】解析：此处意为“______这款联网的按钮，消费者可以轻松预订特定的大宗货物”，需要填入一个介词表实现方式，因此只有A．via适合，表示“通过，凭借”之意。via也出现在倒数第二段中，via a network ofservice providers，仍然是这个用法。
单选题
【C3】
【正确答案】
B
【答案解析】解析：本句Amazon today unveiled Dash Buttons…and yesterday 3 Home Services…．and表示顺接，可见这是一个对称结构，此处需要填一个与unveiled意思相近的词。veil意为“面纱”，unveil即“揭开……的面纱，使公之于众”，结合上下文可知此处表“发行，发布”之意。publish多指出版发行文字作品，也指通过报刊或其他媒介发布新闻等；launch专指向公众推出、发布新产品，也指火箭、卫星等发射；announce多指首次宣布大家感兴趣或可满足大家好奇心的事情；release多用于发布信息、数据、新闻等。因此选B．launched。倒数第二段Amazon also recently launched Home Services也有提示。
【答案解析】解析：此处______-controlled是一个复合形容词，修饰Dash ordering system，后跟定语从句that lets people speak to order…可知这个系统是“声控”的，因此此处填入一个表示“声音”的词。voice专指人发出的语音，sound则指自然界的一切声音，因此D．voice正确。numeral“数字”和gesture“手势”均与题意不符。
单选题
【C6】
【正确答案】
B
【答案解析】解析：此处order new______items，试想人们借助Dash Buttons从亚马逊上都能订购什么货物呢?自然是日常杂货什么都可以了，因此选B．grocery“食品杂货”。文中提到的bulk goods(大宗货物)，Kraft Macaroni and Cheese boxes(卡夫通心粉或芝士粉)也验证了这一答案的正确性。食品、数字产品、自动化产品都是其中的一部分，因此排除其他三项。
单选题
【C7】
【正确答案】
C
【答案解析】解析：此句子的主干是______Amazon has is a retrofit strategy for…and a future-facing strategy for…．可知______ Amazon has为句子的主语，并且连接词在句中有实际的意义，故排除that(that在引导的主语从句中没有实际意义，且后面接完整的句子)。其他两项不能引导主语从句。因此，选C．what。
单选题
【C8】
【正确答案】
A
【答案解析】解析：此句主干为______ Amazon has is a retrofit strategy for…and a future-facing strategy for…，______Amazon has即指亚马逊发布新产品这件事情，后面两个strategy也是两个对称结构，第一个a retrofit strategy for connecting…to…其实已经暗示了答案。亚马逊发布新产品就是为了应对未来大量联网设备上市的浪潮，而且文中多次出现connect，如第一段internet-connected button，capitalizing on connectivity等，因此正确答案就是A．connected “连接的”，文中意为“联网的”。personal“个人的”，automatic“自动的”，electronic“电子的”，均与题意不符。
【答案解析】解析：前面讲一键下单的快捷性令人着迷，此处又说it could lead to a______of packages ending up at people’s doors，if Amazon doesn’t…，可见语气是转折性的。纵观四个选项，只有C．although“虽然，尽管”是转折语气，表示让步，为正确答案。
单选题
【C11】
【正确答案】
B
【答案解析】解析：结合选项可知此处意思是说用户门口有“一堆”包裹，附带假设“如果亚马逊不……”，再结合本句表示让步关系“尽管……一键下单的快捷性仍是令人着迷的”，可知用户门口的包裹应该是杂乱的，a mess of表示“杂乱的一堆”，因此B．mess为正确选项。a pile of指“整齐的一摞”；a pack of指“一捆，一大包”；a group of指“一群”，均与题意不符。
【答案解析】解析：下句the person who can install them提示：这些设备需要专业人士进行安装．因此选择A．professional“专业的，职业的；专门从事的”。special“特殊的；专门的，专用的”，specific“明确的；具体的”，amateur“业余的”，均与题意不符。
