Q21

How the Desolenator works

The energy required to operate the Desolenator comes from sunlight. The device can be used in different locations, as it has 21..............

分析

题目标题跟文章标题比较像，不划为定位词；题干可以划定位词的有energy, sunlight, different locations。空格前面是it has,所以空格是名词。空格所在的这一句前半句是结果，后半部分是条件，所以这里的as理解为“因为”。既然能在不同的地方使用，而且跟设备本身所拥有的东西相关，说明设备有的这个东西是对运输或移动这个设备有帮助的。

定位

C The Desolenator can produce 15 litres of drinking water per day, enough to sustain a family for cooking and drinking. Its main selling point is that unlike standard desalination techniques, it doesn’t require a generated power supply: just sunlight. It measures 120 cm by 90cm, and is easy to transport, thanks to its two wheels. Water enters through a pipe, and flows as a thin film between a sheet of double glazing and the surface of a solar panel, where it is heated by the sun. The warm water flows into a small boiler (heated by a solar-powered battery) where it is converted to steam. When the steam cools, it becomes distilled water. The device has a very simple filter to trap particles, and this can easily be shaken to remove them. There are two tubes for liquid coming out: one for the waste - salt from seawater, fluoride, etc. - and another for the distilled water. The performance of the unit is shown on an LCD screen and transmitted to the company which provides servicing when necessary.

答案

上文第二句出现了定位词sunlight，这句中的power supply对应题干中的energy。上文第三句中的easy to transport对应题干中的can be used in different locations，所以答案在这句中找，这句中的thanks to【多亏；由于】对应题干中的as，所以答案是two wheels。题目要求只能写一个单词，所以最终答案是wheels【轮子】。我们分析的时候说过，这个答案跟移动或运输相关，所以满足要求。

Q22

Water is fed into a pipe, and a 22 ............. of water flows over a solar panel. The water then enters a boiler, where it turns into steam. 

分析

题干可以划定位词的有pipe【管道】， water, solar panel【太阳能板】, boiler【烧水器】和steam【水蒸气】。空格前面是a, 后边是of water，一般a…of 这种结构是表示量词的结构，所以这道题找到跟water挨着的表示量词的结构即可，答案是单数名词。

答案

上文第四句出现了定位词a pipe，这句中的enters through【通过…进入】对应题干中的fed into【注入】，后半句中的flows主语也是前一句的water，所以这句找出表示量词的名词即可，满足要求的词是a thin film【以薄膜的形式】，空格只能写一个单词，所以答案是film。放回空格里构成a film of water【一层薄薄的水流】，语法和逻辑都合理，答案是film。

注意，这句往后有一个a sheet of double glazing，这个结构跟题干也是非常像的，但这个短语前后没有跟water对应的词，而且这个短语中的between…and…是并列结构，题干没有对应的并列，所以我们不能在这个短语中找答案。

Q23

Any particles in the water are caught in a 23 ..............

分析

题干可以划定位词的有particles【颗粒】，空格前面是caught in a 【卡在…里】，所以空格是带有过滤这种颗粒作用的设备，答案是单数名词。

答案

上文倒数第三句出现了定位词particles，前面的词trap【困住】对应题干中的caught in【卡在…里】，所以这句中找出单数名词即可，满足要求的答案只有filter【过滤器】。如果满足要求的答案有两个，那么我们要通过这个词的属性去筛选，如这道题我们分析的时候就说过答案是有过滤作用的单数名词。

Q24

The purified water comes out through one tube, and all types of 24 ............. comes out through another. 

分析

题干可以划定位词的有purified water, one tube【管道】， 空格前面是all types of，后边是comes out，所以空格是名词，单复数都有可能。

The performance of the unit is shown on an LCD screen and transmitted to the company which provides servicing when necessary.

答案

上文倒数第二句出现了定位词tubes，这句中的another for the distilled【净化的】water对应题干中的the purified water comes out through one tube，所以答案在倒数第二句前半部分找。这句中的salt from seawater, fluoride, etc.【等等】对应题干中的all types of, 所以答案是它们的总称，破折号前面的词waste【垃圾；杂质】。所以一定要熟练掌握两个破折号/两个逗号之间的内容是补充说明前面名词的，两者划等号，如：

The famous book, Wealth of Nations, is considered one of the best in its field.

【这本书名的书，国富论，被认为这个领域的最好的著作之一。】

这句中的famous book就是Wealth of Nations。逗号之间的内容在命名前面的内容。

Eminem-the slim shady, a loving father, a bitter husband, a thuggish musician- remains to be my role model。

【Eminem-阴险的瘦子，慈祥的父亲，刻薄的丈夫，流氓版音乐家-仍然是我的榜样。】

这句中两个破折号之间的内容是在拓展描述破折号前面的Eminem，但两者依然是相等的关系。

总结：两个逗号或破折号之间的内容，被称为插入语或同位语，是跟前面的名词是划等号的。如果两个逗号之间的内容比较多，那么它在拓展描述；如果两个逗号之间的内容较少—一道两个词，那么它在概括总结或命名逗号前面的名词。

Q25-26

A screen displays the 25 ..............of the device, and transmits the information to the company so that they know when the Desolenator requires 26 ..............

分析

题干可以划定位词的有a screen【屏幕】，information和company。

第25题空格前面是display the，后半是of the device，所以空格是表示device的特点的名词，而且这句开头说的是a screen，所以屏幕上显示的很有可能是以数字显示的，关于这个设备的一种指标，如压强，温度等。

第26题空格前面是Desolenator requires,所以空格是名词。从标题或审题过程中我们可以看出这个Desolenator是一种仪器，那仪器需要的可以是能源，如汽油，电；也可以是保养或维修，所以空格是跟这些内容相关的名词。

答案

上文最后一句的前半句出现了第25题定位词screen，这句中的is shown【被展示】对应题干中的displays【显示；展示】，所以答案在这句中找，满足要求的答案是performance【表现】。

上文最后一句的后半句出现了第26题的定位词company，这句中的necessary【有必要的】对应题干中的require【要求；需要】，满足要求的答案是servicing【维修】。
