B: modern navigation systems are made of low-power circuitry,which is more susceptible to
interference than the vacuum-tube circuitry found in older planes.  During landing, navigation systems
receive radio signals from the airport to guide the plane to the runway.

Pne plane with low-power circuitry had problems when landing when a passenger turned on a laptop.

C: modern aircraft navigation system is harmed by electronic devices psaaengers carried on board

least strenghthe----削弱

可能是当电子设备开启才会影响

A 提供证据

B 加强

C 削弱..right one 加强
D 支持原文观点,

E irrelevent right one

B: unusual severe winter in Europe
P:blue haze from eruption of a volcano in Europe
C:eruptions cause air to become cooler

问weaken
可能有其他原因导致冷

A:。。。
B:inrevelent
C:对 （不确定QAQ
D:有削弱，但是暂时的
E 加强了论点

B: most microwave have clocks and they consume 45 per year
C: microwave without clocks consume less than 45 a year

问哪个假设可以得出此结论（重点在有无时钟花费的能量

A:是microwave有无时钟的比较，而不是有没有microwave的比较
B:与microwave的价格无关
C:与其他的工具无关
D:right
E不是比种类的数量


B:some airlines reduce fares on routes in order to compete with competitors
Pnce an airline implements this method,  any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.
C:this method can't be profit in long run

问削弱，如果公司不需要再提高价格就能盈利

A:这是加强
B：与问题无关
C:这也是加强。。而且题中已经提到
D:无关
E：对
正确答案是B，做这个题我重点关注在降价的公司上而忽略了题目的重点还有怎么驱逐竞争者上......但这个也太绕了
B:when repaining of a plane, it can;t be mantaince as well,thus cost lots of time
P:a new film can be used and take the same time while lots of mantainance works can be carried out
问支持的证据 goal是缩短维护时间

A:无关
B:对
C:无关
D:无关
E:无关。。。

Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes.  However, this method of eliminating competition cannot be profitable in the long run.  Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.
Which of the following, if true, most seriously weakens the argument?
(A) In some countries it is not illegal for a company to drive away competitors by selling a product below cost. Irrelevant
(B) Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge-correct answer
If there is competitor, the reduced price will maintain, then no opportunity is left to the competitors-from a DN.
(C) As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level. Already stated in the passage
(D) On deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations. Irrelevant
(E) When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.
This is the most attractive wrong answer. The conclusion is about the consequences of airlines’ attempt to recoup the earlier losses by charging high fares. So what happens during the promotions period is irrelevant.

When an airplane is taken out of service for maintenance, it is often repainted as well, and during the repainting no other maintenance work can be done on the plane.  In order to reduce maintenance time, airline officials are considering using a new nontoxic plastic film instead of paint.  The film takes just as long to apply as paint does, but many other maintenance tasks can be carried out at the same time.

Which of the following, if true, is further evidence that using the film will help the airline officials achieve their goal?

(A) Unlike paint, the film gives a milky tone to certain colors. irrelevant
(B) At the end of its useful life, the film can be removed much more quickly than paint can.-thus save time, correct answer.
(C) The film can be applied only by technicians who have received special training. irrelevant
(D) The metal exteriors of airplanes have to be protected from high temperatures and caustic chemicals such as exhaust gases. irrelevant
(E) Even at speeds considerably higher than the normal speed of a passenger jet, the film remains securely attached. Irrelevant, the goal is about time-saving, security is out of scope.
Analysis:
The goal is to reduce maintenance time. Find out an option that prove that this film can really save time.

BG：modern navigation system with low-power circuitry>older
During landing, navigation system receive signal from plane.
P: one plane with modern navigation system had an accident because of a laptop computer
C:MNS are being put at risk by the electronic devices.

A:least strengthen

猜测Strengthen: 得知laptop和许多electronic devices的影响相同

(A) After the laptop computer was turned off, the
plane regained course and its navigation
instruments and dials returned to normal.
证明是laptop的影响
(B) When in use all electronic devices emit
electromagnetic radiation, which is known to
interfere with circuitry.
在使用时 所有electronic devices都发出公认影响circuitry的ER
(C) No problems with navigational equipment or
instrument dials have been reported on
flights with no passenger-owned electronic
devices on board.
没electronic devices的没问题
(D) Significant electromagnetic radiation from
portable electronic devices can travel up to
eight meters, and some passenger seats on
modern aircraft are located within four meters
of the navigation systems.
ER可达到8米，而electronic devices离4米
(E) Planes were first equipped with low-power
circuitry at about the same time portable
electronic devices became popular.

B：Modern navigation system is more susceptible to interference than CT.
P1: during landing, NS receive radio signals
P2: One plane was influenced when a passenger turned on a computer
C:NS are being put at risk

E,irrelevant


B:Most household appliances use E only when in use
P1: Many MOs have build-in clocks and so use some E when they r not in use
P2: The clocks comsume about 45 KH per year
C: MO that has no built-in close use 45 KH less
