我们先浏览一下Test 1三篇文章的题目，题型包括段落细节定位题，summary 题，heading题，判断题及选择题，这些都是历届雅思考试主流常考题型，建议考生们做套题时贵在沉住气，静心，对做题顺序做整体的把握，并充分运用各题型的做题方法。

就PASSAGE 1做具体讲解，QUESTIONS 1-5 是个段落细节定位题，这种题型要求我们基本上每一段都要看而且段落从头到尾都得看，非常耗时，而且准确率不算高，通常情况下我们把这五道题留到最后去做，做完后面的题目对这道题是有帮助的。

QUESTIONS6-9 是个SUMMARY, 我们看题目要求，并没有段落限制，很有可能答案就会很分散，但也不排除答案集中的情况。QUESTIONS 10-13 是个句子填空题，那么SUMMARY 题和句子填空题是相通的，它们都是填空题，在很多情况下，都是通过定位词找细节，所以我们可把这两道题结合着做，划好QUESTIONS 6-13的定位词，去原文从第一段看起来，找细节。

第6题通过facial vision, pain, arm, leg 等定位词，定位在D 段，即 like the referred pain in a phantom limb, 与题目的pain from a ______ arm or leg 进行了同义转换，答案为 phantom.

第7题 the ability actually comes from perceiving ________ through the ears( 这种能力通过耳朵感知什么而得到). 我们按顺序原则从原文继续往下看 the sensation of facial vision , it turns out, really goes in though the ears. Blind people, without even being aware of the fact, are actually using echoes of their own footsteps and of other sounds, to sense the presence of obstacles. 定位词ears 出现，那么对这句话做理解，这种facial vision的感觉是通过耳朵得到的，盲人(没有意识到这一点)通过耳朵感受回声来感知障碍的存在。答案即为 echoes/ obstacles. 通过这道题perceiving ________，(感知 …)我们发现找动词后面即为答案，sense the presence of obstacles.

第8题定位词为instrument, calculate. 原文before this was discovered, engineers had already built instrument to exloit the principle, for example to measure the depth of the sea under a ship.动词后为答案，calculate 和measure 同义转换, 即测量depth.

第9题定位词为wartime, device, finding. 原文after this technique had been invented, it was only a matter of time before weapons designers adapted it for the detection of submarines. Finding 和detection 同义转换，即探寻 submarines.
