(2017·山东实验中学一模)
Global Positioning Systems (全球定位系统) are now a part of everyday driving in many countries.These satellitebased systems provide turnbyturn directions to help people get to where they want to go.However，they can also cause a lot of problems，send you to the wrong place or leave you completely lost.Many times，the driver is to blame.Sometimes a GPS error is responsible.Most often，says Barry Brown，it is a combination of the two.
Barry Brown is with the Mobile Life Centre in Stockholm，Sweden.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPSequipped car to use during his stay.Mr Brown says，“They just plugged in an address and then set off to their destination.And，then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again，the GPS is kind of ‘garbage in garbage out’．”
Mr Brown says this is a common human error，but what makes the problem worse has to do with some of the shortcomings，or failures，of GPS equipment.He says，“One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn，sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Mr Brown says，“One of the things that struck us，perhaps the most important thing was that you have to know what you’re doing when you use a GPS.There are these new skills that people have developed.There are these new competencies (资格) that you need to have to be able to use a GPS because they sometimes go wrong.This goes against a common belief that GPS systems are for passive drivers who lack navigational skills.”
Barry Brown says to make GPS systems better we need a better understanding of how drivers，passengers and GPS systems work together.
1．According to Barry Brow，in most cases，________are blame for the problems.
A．human errors
B．GPS errors
C．errors caused by both drivers and GPS
D．errors caused by putting in a wrong address
2．The example of Barry Brown’s friend is used to show that________.
A．GPS is nothing but garbage
B．GPS is still not accurate enough
C．it is difficult for drivers to use GPS equipment
D．sometimes drivers are responsible for the problem
3．It can be inferred from the second paragraph that________.
A．it’s impossible to drive from the east to the west in the US
B．Barry Brown’s friend went to Stockholm，Sweden by plane
C．given wrong instructions，the GPS will produce wrong results
D．GPS systems are for passive drivers who lack navigational skills
4．Which of the followings is one of the shortcomings of GPS equipment?
A．It just tells the driver to turn once at a time.
B．It gives the driver the overview.
C．Its screen is too small to be seen clearly.
D．It is only suitable for passive drivers.
5．What’s the main idea of the text?
A．GPS systems are helpful for drivers.
B．Driving with GPS can be difficult to navigate (导航)．
C．Drivers should understand how GPS systems work.
D．Drivers should learn to use GPS systems correctly.
课时作业(八)
.单项填空
1．解析： 考查交际用语。根据“but I’ll have to check my schedule for sure”可知，此处表示“应该没问题，但还要查看一下时间表确定一下”，因此选B。
答案： B
2．解析： 考查冠词。句意为：据说澳大利亚产的羊毛质量很好。“produced in Australia”是后置定语，修饰wool，所以第一空用the表示特指；第二空是“be of＋抽象名词”结构，名词前不用冠词。
答案： B
3．解析： 句意为：看到街道的拐角处有一大群人，我意识到有什么不寻常的事情发生了。unusual作后置定语修饰 something。
答案： B
4．解析： 句意为：聪明的人常常能使复杂的事简单化，然而愚蠢的人更有可能使简单的事复杂化。本题考查动词辨析。sacrifice牺牲，奉献；substitute代替，取代；simplify使……简单化；survive幸存，幸免于。前后分句表对比，故C项符合句意。
答案： C
5．解析： 考查动词的时态。根据语境可知，drink这一动作发生在表示感谢之前，是过去发生的动作，所以用一般过去时。
答案： A
6．解析： 考查非谓语动词。句意为：由于缺乏社会交流而造成的误解，如果得不到恰当的处理，可能会导致严重的问题。第一空，Misunderstandings和arise为逻辑上的主谓关系，所以用arise的现在分词形式，arise from意为“由……产生”。第二空，handle和Misunderstandings为逻辑上的动宾关系，所以用handle的过去分词形式。
答案： B
7．解析： 考查情态动词。句意为：据说这家店里有很多种外套，你应该很容易就能够找到一件合适的。should表示“应该”，符合句意。
答案： D
8．解析： 考查状语从句。句意为：在我从媒体了解更多的信息之前，我不明白为什么叙利亚问题会变得如此复杂。 before意为“在……之前”，符合句意。

答案： D
11．解析： 考查连词。句意为：——你是怎么通过这么有挑战性的考试的？——我过了很长时间后才找到一系列合适的办法。分析句意可知，这是“It was＋时间＋before从句”句型，主句为肯定句，意为“过了多长时间之后才……”，before在……以前。
答案： D
12．解析： 考查副词。句意为：我也许会失败，但是无论怎样，我会坚持做的。我永不灰心。anyhow无论如何，反正，符合句意。A.用某种方法，不知为什么；C.然后；D.同时。
答案： B
13．解析： 考查状语从句。根据so...that...如此……以至于，得出答案。
答案： C
14．解析： 考查动词短语辨析。deal with处理，应付；应对；agree with同意；赞同；turn out结果，原来是；put out扑灭；生产。
答案： A

答案： D
.完形填空
语篇解读 本文是一篇夹叙夹议文。生活中我们常常会遇到这样的情况，明明喝的是咖啡却非常在意装咖啡的杯子，殊不知咖啡杯只是一个器具，杯中的咖啡才应该是真正的旨趣所在。
1．解析： 考查名词辨析。根据本句的“stress”及下文第二段末句中的“problems and stress”可知，此处应该是抱怨生活和工作中的压力。
答案： B
2．解析：
考查名词辨析。根据第一段内容可知，学生们来看望教过自己的大学教授，对于教授来说这些学生就是客人。

答案： B
4．解析： 考查名词辨析。从破折号的解释可看出，教授拿来许多不同的咖啡杯。如果选择A项则意为“一种杯子”，与下文的叙述相悖。a variety of cups意为“各种各样的”，符合语境，故选C。
答案： C
5．解析： 考查动词辨析。help oneself to是固定搭配，意为“随便用(或吃)”。教授拿回不同的杯子和咖啡让学生自便，从而引出下文教授的评价与教导。
答案： C
6．解析： 考查动词辨析。教授拿出许多不同的咖啡杯，这是教授引起学生注意的方式，所以教授说：“你们都注意到了”。因此答案选D，noticed意为“注意，关注”。

答案： D
8．解析： 考查形容词辨析。此空所填词应该与plain构成并列关系，所以选择A项，另外cheap与本句中的“expensive”也是相对的。
答案： A
9．解析： 考查连词辨析。根据下文可知。“the best”和“problems and stress”形成对比，故此处应该选择表示转折意味的词语。while意为“虽然”，符合语意语境，故答案选B。
答案： B
10．解析： 考查名词辨析。句意为：虽然你只想给自己选择最好，这是人之常情，但是这也正是你们的问题和压力的根源所在。根据句意可知，应选择B项，source意为“根源”。
答案： B
11．解析： 考查动词辨析。add to意为“增加”，即教授认为杯子本身不会增加咖啡的质量。故答案选D。increase一般表示具体数量上的增加；expand意为“扩大，增加，增强(尺码、数量或重要性)”；extend意为“使伸长，扩大，扩展”，均不符合题意，故排除。
答案： D
12．解析： 考查介词短语辨析。in most cases意为“在大部分情况下”，与本句中的“in some cases”相呼应。
答案： B
13．解析： 考查动词辨析。根据语境可知，此处指“我们所喝的咖啡”，what引导宾语从句，在从句中作宾语，指代咖啡。
答案： A
14．解析： 考查副词辨析。选择咖啡杯是有意识地选择。
答案： C
15．解析： 考查动词辨析。自己已经选择了自认为是最好的杯子，选好之后还要打量别人的杯子。eye用作动词，意为“注视，审视，细看”，符合语境。suspect一般不用于进行时，意为“怀疑”；envy意为“嫉妒”；consider意为“考虑”，均不符合语境。
答案： D

答案： C
19．解析： 考查动词辨析。句意为：有时候人们只关注盛咖啡的杯子，而没能品尝出咖啡的味道。言外之意是人们过于关注生活的外在表现形式，而忽略生活的真正内涵。fail to do sth.意为“不能做某事”，符合语境，
答案： D
20．解析： 考查动词辨析。本句是全文的结束句，也是对全文的总结，即不要让杯子牵着你走，应该享受咖啡本身。drive此处表示“迫使，驱使”，符合语境，故选B。
