(solve).They 3. (design) a “smart surface” that can boost the WiFi signal in your home by nearly 10 times. 2．考查词性转换。句意：现在，美国麻省理工学院(MIT)的一组工程师可能有了一个解决方案。根据该空前的have a可知，其中have是及物动词，后面应该跟名词作宾语，冠词a修饰名词单数，solve的名词形式是solution。故填solution。 答案：solution 3．考查动词时态和主谓一致。句意：他们已经设计了一种“智能表面”，可以将家中的WiFi信号提升近10倍。根据上下文可知，该句运用现在完成时，表示过去发生的动作对现在造成的影响或结果，主语they是复数，故填have designed。 答案：have designed The smart surfaces are paper-thin，so they can be installed like wallpaper.They contain thousands of tiny antennas (天线) but don't need power or wiring.All they do is reflect 4. (signal).A smart surface can work both as a mirror or a lens to focus radio signals onto the right devices.By doing so，it increases the median signal strength by nearly 10 times，5. (double) the median channel capacity in an office environment. 4．考查名词单复数。句意：它们所做的只是反射信号。该空前的reflect是及物动词，其后跟名词作宾语，此处用复数形式signals，表示泛指一些反射信号。故填signals。 答案：signals 5．考查非谓语动词。句意：通过这样做，它将信号强度中值提高了近10倍，使办公环境中的中值信道容量增加了一倍。分析句子结构可知，该句的主语是it，谓语是increases，因此，double应该用非谓语动词形式，double与逻辑主语it之间是主动关系，因此用double的现在分词形式doubling作状语。故填doubling。 答案：doubling According to the researchers，the smart surfaces would allow 6. (small) devices to be made，like tiny sensors that detect the indoor pollution levels or those that monitor machines in a warehouse.These were 7. (previous) believed to be too small 8. (give) off a strong enough WiFi signal. 6．考查形容词比较级。句意：根据研究人员的说法，这种智能表面可以制造出更小的设备，比如检测室内污染水平的微型传感器或者监控仓库里机器的传感器。根据下文“like tiny sensors that detect the indoor pollution levels or those that monitor machines in a warehouse”中的tiny可知，该句指制造出“更小的”设备，small的比较级是smaller，故填smaller。 答案：smaller 7．考查词性转换。句意：以前人们认为这些设备太小，无法发出足够强的WiFi信号。根据该空后的动词believed可知，该空应该填副词previously修饰动词believed作状语。故填previously。 答案：previously 8．考查固定搭配。句意：以前人们认为这些设备太小，无法发出足够强的WiFi信号。根据句意“太小，而不能(发出足够强的WiFi信号)”可知，该句考查短语too...to...结构，意为“太……而不能……”，所以填to give。 答案：to give In addition 9. easy usage，it will probably be relatively cheap.According to the estimations，such a setup could probably cost you a few cents per antenna.10. bright side is that it would consume less power compared to conventional systems. 9．考查固定搭配。句意：除了使用方便，它可能会相对便宜。短语in addition to意为“除了……”，该空缺少介词to。 答案：to 10．考查代词。句意：另一个好的方面是，与传统系统相比，它的功耗更低。上文已叙述了一个好处，这里提到另一个好处，用another；置于句首时，首字母大写。故填Another。 答案：Another $$
