英语综合知识运用又名完型填空，这道题目要做好需要同学过三关，词汇关，句法关，和篇章关。此外还需要同学们掌握科学的做题顺序。即，1.抓主线2.正面理解语义去预测选题与根据选项来反推相结合。 今天我们重点来学习抓主线，因为主线是文章的论点和灵魂。那主线从哪找呢?因为完型是十分典型的议论文，那么完型的主线所在的位置就和我们议论文所在的位置是一样的，首段和段首。在这里尤其是要注意的是，完型填空有一个十分重要的特征就是，首句不设空，所以建议同学们花三倍的时间去研究不设空的首句。下面我们以2012年完型为例给同学们示范如何找主线。
People are, on the whole, poor at considering background information when making individual decisions. At first glance this might seem like a strength that 1 the ability to make judgments which are unbiased by 2 factors. But Dr. Uri Simonsohn speculated that an inability to consider the big 3 was leading decision-makers to be biased by the daily samples of information they were working with. 4 , he theorised that a judge 5 of appearing too soft 6 crime might be more likely to send someone to prison 7 he had already sentenced five or six other defendants only to probation on that day.
首段中but 之前为作者引用的大家普遍的观点，认为在做决定的时候不考虑背景信息是一个优点，可以促使做出一个公正的判断。然而作者却提出了相反的观点， 作者认为，不考虑背景信息，致使决策者在做决定的时候容易受到一些自己所处理的其他案例的信息干扰，反而会做出一个不公正的判断。 作者用一个法官在判决的时候因为担心对前面几个被告这量刑太轻，而会将后面的被告者给予重型，送到监狱去。 这个例子来佐证自己的观点。
To 8 this idea, he turned to the university-admissions process. In theory, the 9 of an applicant should depend not on the few others 10 randomly for interview during the same day, but Dr Simonsohn suspected the truth was 11 .
第二段首句告诉我们作者为了进一步证明自己的观点，转向大学录取的过程做实验。
He studied the results of 9,323 MBA interviews, 12 by 31 admissions officers. The interviewers had 13 applicants on a scale of one to five. This scale 14 numerous factors into consideration. The scores were 15 used in conjunction with an applicants score on the Graduate Management Admission Test, or GMAT, a standardised exam which is 16 out of 800 points, to make a decision on whether to accept him or her.
第三段作者主要描述的是大学录取的过程，即就是，作者实验的经过。
Dr Simonsohn found if the score of the previous candidate in a daily series of interviewees was 0.75 points or more higher than that of the one 17 that, then the score for the next applicant would 18 by an average of 0.075 points. This might sound small, but to 19 the effects of such a decrease a candidate would need 30 more GMAT points than would otherwise have been 20 .
第四段作者总结对大学录取的抽样研究的发现，理论上一个申请者面试的成功应该取决于自己的实力，结果作者发现，面试官在打分的时候，会受到前后申请的打分的情况的影响，而做出不公正的判断，进而证明了首段的观点。
通过上面首段和段首的分析，在没有通读全文的情况下，我们迅速的掌握了文章的主旨大意。不仅节约了时间，而且也提高了做题的正确率。所以建议同学们在做完型填空这道题目时候，先去了解大意，通过抓主线即可，不需要通读全文。
