【雅思听力】雅思听力陷阱之限定词解析

　　used to be和originally都是original的同义词，而originally那句跟的就是park用于干扰。所以答案应该是factories，选项B就是factories的同义词，故答案为B。

　　原文：I went there in 1993 just after graduating from university. After three years of studying,  I wanted adventure. I loved travelling, so I decided to join a voluntary organization and was sent to Ecuador to carry out land surveys.

　　In 1993 Dan Pearman went to Ecuador

　　A． as a tourist guide

　　B． as part of his studies

　　C． as a voluntary worker

　　1993后紧跟着after graduating from university，所以马上排除选项B，后文中出现了voluntary organization，故答案为C。

　　原文：The area has been famous for centuries for making beautiful carpets, although recently there has been a trend to move into weaving blanket and wood carving.

　　The Semira region has a long tradition of

　　A． making carpets

　　B． weaving blankets

　　C． carving wood

　　虽然此题不像上面两题有非常清晰的时间指示词，但是题干中long tradition of带有明显的“过去”时间指示特点。has been famous for centuries与has a long tradition为同意转换，故答案为选项A。而B、C 两个选项紧跟recently这个时间状语用于干扰的。

　　其实时间限定词很多，包括明确限定和隐性限定两类。明确限定的有now、past、future、use to、original、originally、soon、so far、recently、current、currently、soon等；例如上题中的has a long tradition就是隐性限定。
