sheer volume But I soon became struck by was the sheer volum

雅思听力里面的!　Tapescripts：
　　My topic is handedness - whether in different sports it is better to be left- or right-sided or whether a more balanced approach is more successful.I'm left-handed myself and I actually didn't see any relevance to my own life when I happened to start reading an article by a sports psychologist called Peter Matthews.He spent the first part of the article talking about handedness in music instead of sport,which I have to say almost put me off from reading further.But what I soon became struck by was the sheer volume of both observation and investigation he had done in many different sports and I felt persuaded that what he had to say would be of real interest.I think Matthews' findings will be beneficial,not so much in...
　　这边作者先介绍了一下自己的情况,也就是"left-handed",这里和选项A比较相近,但是此时并没有读出题干来,因此我们完全可以排除A这个答案.（根据我们上面提到的顺序原则）接下来,作者提到了"Peter Matthews"这个人,并且提到了music,也就是和B很相近,此时他的态度是"almost put me off",这个和题干中的"of value"矛盾,也就是这个也不是答案.此时我们已经可以很顺利的选到正确答案C了.——将错误的信息全部排除,剩下的就一定是正确的答案.
　　当然此题可以通过同义词互换做出来,也就是这边标注了答案的地方:"sheer volume"和C选项中的"impressive size"是类似的意思.但是很多同学会发现,这个词比较难听懂.也就无法很快的找到答案了.
