【英语】完形填空中连词与介词题的快速定位之法

1.完形填空中连词的选择  

连词一般用来表示原因、结果、让步、对照、补充、目的、条件等关系。表示原因的连词：because, since, as, now that等；表示转折和让步的连词：but, though, although, whoever, whatever等；表示时间顺序的连词：when, while, as, after, before, since, until, as soon as, once等；表示目的的连词：so that, in order that等；表示条件的连词：if, supposing (that), unless, in case, so (as) long as等。

连词在高考完形填空题中考查的题目不是很多，一般是一两个。对于连词的选择考生往往要注意前后句子之间的逻辑关系以及句子本身的结构。

例1 Some individuals find adventure in the simplest forms. For example, if you have never been out of your own country and you decide to tour Europe, guess what! You are engaging in adventurous activity! Conversely, some people consider adventure as something that increases the adrenalin (肾上腺素)and are not happy ______  they go skydiving or bungee jumping! Again, any form of adventure is good as long as the adventure travel pursued remains within the comfort zone of the individual.

A. unless                     B. since                        C. before              D. because 

【解析】A。考查连词的辨析。此处意为"相反，有些人认为冒险是一种可以增加肾上腺素的活动，除非他们能够进行高空跳伞运动或者蹦极运动，否则他们就会不高兴"。因此这里选unless,表示一种条件关系。而since,because表示原因；before表示时间，均与句意不符。

例2 Talent between the two? Probably the same. Level of education? Not much difference. But the Stranglers strangled,_______the Wranglers were determined to give each other a lift. The Stranglers promoted an atmosphere of argument and self\|doubt. The Wranglers highlighted the best, not the worst.

A. although           B. if                     C. because             D. while

【解析】D。考查连词的辨析。他们的教育水平有什么不同吗？没有多大的区别。但是那些Stranglers多进行批评，然而那些Wranglers却决心给予对方以帮助。由此可以看出此处是一种转折和对比的关系，因此选D。而although"虽然";if"如果";because"因为"，均与句意不符。 

 

2.完形填空中介词的选择  

       介词和介词短语在高考完形填空中不是经常考查的重点,但是在2010年各地的高考试题中还是有所体现的。选项中的四个不同的介词或者介词短语没有紧密的联系，选择它们需要借助于固定搭配或者前后文的语境。

例1  If we had done nothing, if we allowed ourselves to "stay down", then we would have failed. But we made the choice to learn from our offers, and we moved forward  _______]   more determination. That quote mistakes a much better viewpoint on failure — a chance for a fresh start! The most important point here is "choice" because you decide how you view your failure, you decide if you stay down.

A. with                 B. of                    C. at                            D. from

【解析】A。考查介词的选择。如果我们什么也不做，如果我们放纵自己，"留级"的话，那么我们就会失败了。但是，我们可以选择向他人学习，并且以自己坚定的意志前行。with表示"具有"，符合语境。of表示"属于（某人）"，at表示"在(学习或工作地点)"，from表示"从……(到)"。

例2  Even when passing through the roughest period of our life, we can turn it in our favor by hard and righteous work. No good deed goes ________being paid off and it does have the power of changing the fortunes.

For example, if one has worked for 20 hours in a week, the employer will pay for 20 hours. Similarly if we are walking on the path of positivity with great faith in the life, performing our deeds, we’ll be paid off. 

A. off                   B. out                   C. on                           D. without

【解析】D。考查介词的选择。此处意为"没有好事不会得到回报的，并且它的确可以具有改变我们命运的力量"。因此选D。go off表示"爆炸，开火，中断，不再喜欢"；go out"外出，交际，过时，退潮，公布"，go on"持续，出场，过去",均不符合语境。
