[雅思培训]雅思听力技巧：火眼金睛，横扫限定

经过研究和总结，雅思选择题里的限制条件可归为三类：时间限定、频度限定、名词限定，下面我就逐一进行解析。

类：时间限定

例1 剑7 Test 4 Q 12

The original buildings on the site were

A houses

B industrial buildings

C shops

思路透析：题干中包含original这一时间限定词，所以提前预判此题干扰项为现在这些建筑是干什么用的并且做好排除干扰项和同义转换的准备。

实际做题：在实际做题中，当听到used to be...这个表达方式的时候就应该有所警觉，做题位置到了。

          原文：There used to be a lot of factories in this area until 1960s. Creating the park required the demolition of lots of derelict buildings on the site, so most of the exciting park space all around you was originally warehouses and storehouses.

          解题：无论是used to be 或者是originally 都可以跟original 形成同意转换，而其后的名词 factories，warehouses and storehouses 都可以与industrial buildings呼应，故答案为B。而在上述描述中我们可以看出来现在这块地是一个公园，这只是干扰项而已。

例2 剑5 Test 2 Q 11

In 1993 Dan Pearman went to Ecuador

A as a tourist guide

B as part of his studies

C as a voluntary worker

思路透析：在审题中发现有1993这个时间点，所以确定答案在出现1993这个时间之后，而没有这个时间相随的则为干扰项。

实际做题：出现1993后，做题位置到来。

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

          解题：1993后紧跟着after graduating from university，所以马上排除B选项。而后面发现有voluntary organisation，故确定答案为C。

例3  剑7 Test 3 Q 16

The Semira region has a long tradition of

A making carpets

B weaving blankets

C carving wood

思路透析：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，从而判断干扰项为现在这个地区以作什么为特色。

实际做题：以选项中的各个名词为定位点

          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.

          解题：has been famous for centuries 与 has a long tradition 形成同意转换，故正确答案为A。而B, C两个选项紧跟recently这个时间状语，符合干扰项的特点，故加以排除。

总结： 朗阁海外考试研究中心分析认为，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：具体年代、now、past、future、use to、original、originally、soon、so far、recently、current、currently、soon等；隐性限定：比如例二中的long tradition之类的表达方式或者是时间状语从句。善于发现和利用这样的限定词对解题帮助很大。

第二类：频度限定

例4  剑2 Test 4 Q 35

The most common type of road rage incident involved

A damage to property

B personal violence

C verbal abuse

思路透析：此题题干中出现了most common这种表示频率的词，那么势必出现road rage的种种表现作为干扰项，而我们要等的是较为普遍的一种形式的同意转换。

实际做题：

原文：Well, as you can see, 93% of respondents had had some kind of problem. A surprisingly large percentage-24% had had their car damaged in some way, but the main type of incident was being shouted at-79% had experienced that. 15% had experienced violence on their own persons... they’d actually been hit by someone.

          解题：正如我们所料，出现了violence和damage等road rage的表现形式作为干扰项，而我们所需要的是把most common 和main type做同意转换，进而得到答案C。

例5  剑2 Test 3 Q 8

The respondents feels that adverts should occur every

A 10 minutes

B 15 minutes

C 20 minutes

思路透析：通过这个题的出题形式，能够看出是纯粹考查频率的一道题。

实际做题：听到how often 这个问题时确定做题位置。

          原文：Well out of that list I’d say every quarter of an hour. I don’t think we can complain about that, as long as they don’t last for ten minutes each time!

          解题：此题用每次广告所持续的时间
