错题一

The advantage of the technique being developed by Diels is that it can be used ____
答案:safely
题号:5
定位词:Diels
第五段:… try to use lasers to discharge lightning safely…
用人名Diels在文中定位到第五段,从题目看出这里应填入一个副词,所以可以在人名周围寻找use或者use的替换词,并且在其周围找带有-ly形式的词,这样正确答案safely很快就能浮出水面了。

错题二

This laser is then directed at storm clouds in order to control electrical charges, a method which is less dangerous than using ____.

答案: G. rockets
题号:9
定位词:less dangerous
第五段:…who would want to fire streams of rockets in a populated area?
… try to use lasers to discharge lightning safely…
这道题比较麻烦,对于只是按照顺序寻找答案的考生,定位答案会比较困难。这里需要联系第五段中的信息,参照词库里的单词,推测出空格所在句的意思是“用激光控制闪电是比用火箭更安全( less dangerous )的方式”。正确答案是G。

错题三

As a protection for the lasers, the beams are aimed firstly at _____
答案: D. mirrors

题号:10
定位词:protection, aimed firstly at
第六段:To stop the laser itself being struck… Instead it would be directed at a mirror…
protection对应文中的stop…being struck;at是解题关键词,即使不知道文中的directed和题目中的aimed是同义词,也可以从词组的形式上看出来两者是同位的,其后的名词即为答案。由此可知答案是D。

错题一

给C段落选择适合的标题
答案: iii. two coincidental developments 两个巧合的发展

定位词:coincidental, developments
C段前两句 In the 1940s, ATC centres could and did take advantage of the newly developed radar and improved radio communication brought about by the Second World War… It was only after the creation of the FAA that full-scale regulation of America’s airspace took place, I and this was fortuitous, for the advent of the jet engine suddenly resulted in a large number of very fast plans…demanding some set of rules to keep everyone well separated and operating safely in the air. C段首句说明了ATC取得的第一个development,即利用了第二次世界大战催生出的新研制的雷达和改进后的无线电通讯技术而建立的不成熟的管制系统。第二句则提到喷气式发动机的产生突然导致大批快速飞机的出现,因此促使美国开始进行全面的空中管制,两个逗号之间的部分指出了这一development的偶然性(fortuitous),与中的coincidental含义一致。因此答案为iii。

错题二

给E段落选择适合的标题
答案: iv. setting altitude zones
定位词:altitude zones
E段第二句以及其他关键词:First, ATC extends over virtually the entire United Sates.
E段第二句中提出让航空交通管制几乎遍及整个美国,接着分别讲述了不同高度的空域管制情况(from 365m above the ground and higher, 215m above the ground, below365m…)。因此答案为iv。

错题三

Beacons and flashing lights are still used by ATC today.

正确答案:NG

参考译文:灯标和闪光灯至今仍被ATC使用。
定位词:beacons and flashing lights
B段:…while beacons and flashing lights were placed along cross country routes to establish the earliest airways.
此题的定位词在文中原词出现,按照顺序原则可以迅速定位。文中定位处仅指出beacons和flashing lights在当时的使用情况,对于题干中所指的如今的使用状况只字未提。故此题答案为NOT GIVEN。

错题四

Class F airspace is airspace which is below 365m and not near airports.
正确答案:T

参考译文:F级空域为365米以下的区间且离飞机场不近。
定位词:Class F, 365m
G段:Uncontrolled airspace is designated Class F…
通过定位词Class F可快速定位至此处,但是只能确定Class F为uncontrolled airspace,通过该短语及365m可继续定位于E段。
E段:In general, from 365m above the ground and higher, the entire country is blanketed by controlled airspace. In certain areas, mainly near airports, controlled airspace extends down to215m above the ground…
此句说明从365米往上的区间为controlled airspace,且在大部分near airports的区域, 215米以上的区间都是controlled airspace,因此可以逆推出uncontrolled airspace的情况。故此题答案为TRUE。

错题五

All aircraft in Class E airspace must use IFR.
正确答案:F

参考译文:E级空域的所有飞机必须使用仪表飞行规则。
定位词:Class E, IFR
G段:The difference between Class E and A airspace is that in Class A, all operations are IFR, …
此题通过定位词能够迅速定位。定位句的含义为“E级和A级之间的区别在F A级领空中
所有的操作都遵循仪表飞行规则”显然题干信息与定位句内容矛盾。此题还可以按照绝对化词汇all和must来快速判定答案。故此题答案为FALSE。
