30. In order to recover their share of the world market, U.S. auto makers are ____.
A. improving product quality
B. increasing product features
C. modernizing product style
D. re-positioning their product in the market
根据题目，我们可以很容易定位到该文章的最后一段中的文字：
… American auto manufacturers are using quality improvement as one way to recapture worn markets. Note, also, how auto manufactures once changed styles dramatically from year to year to keep demand from falling.
这道题目其实很简单，但是部分同学很有可能被note后面的内容所迷惑，而选项C、modernizing product style正是根据此所出的干扰项。大家只要注意问题中auto makers are，可以对应段落中的… manufacturers are using…，这里用的是现在进行时；而… manufactures once changed …这里用则是一般过去时，就可以很容易去掉这一干扰项。
再如
Cet-4 2001.1 Passage 4
37. The returned plastic bottles in New York used to ___.
38. What was the attitude of doctors towards weight training in health improvement?
A. positive
B. indifferent
C. negative
D. cautious
在这里通过was我们可以得知是以前医生的观点，那么很容易定位到…since medical opinion suggested that weight-training programs offered few if any health benefits.
另外，本篇文章里的37题的题目中的early spas的定位也很重要，很多人会认为早期的spas是指in the late1960s and early 1970s，我们不能想当然的认为距离现在远就是早期，文章中还出现了a number of fitness spas existed prior to this aerobic fitness movement even a national chain with spas in most major cities.可见这个是出现在60年代末和70年代初之前的。
