　　题型难度分析：

　　段落配考察信息的查找能力，乱序，难度较大，需要烤鸭短时记忆题干的能力，在文章中筛选出有效信息。

　　题型技巧分析：

　　段落配做题技巧

　　1. 完全乱序

　　由于这种题型是要求把细节信息与所在的段落进行配对，因此是绝对打乱顺序出题的。

　　2. 部分题目存在重复选项

　　在雅思阅读中，段落细节配对题以两种形式出现，一种是每个选项只能用一次，另外一种题型，在Instruction的最后一句往往有这样的提示：NB You �may use any letter more than once.

　　如果出现这样的提示，则说明某些段落可以重复选用。剑桥真题集中的真题以及笔者、考生的实际考试经历证明，这种指令往往意味着有且仅有一个选项可以使用两次。

　　3. OG以及近期考题回顾未必是第一个题型

　　如果不是第一个题型出现一般难度会降低，前面的题目按顺序出题，最后完成段落配即可。而且这种题型与段落标题配对题型List of �headings属于“相克题型”，即这两者不可能同时出现。

　　4. 有部分题目与其后的题目有关联

　　由于这种题型一般都是跨全文出的，因此跟后面的题目不可避免地出现交叉，因此有可能根据后面的题目来推断出细节所在的位置。

　　Reading Passage 3

　　Title：Mechanism of Linguistic Change

　　Question types ：填空;判断;长句匹配

　　文章内容回顾

　　参考文章：

　　Mechanism of Linguistic Change

　　The changes that have caused the most disagreement are those in �pronunciation. We have various sources of evidence for the pronunciations of �earlier times, such as the spellings, the treatment of words borrowed from other �languages or borrowed by them, the descriptions of contemporary grammarians and �spelling-rormers, and the modern pronunciations in all the languages and �dialects concerned. From the middle of the sixteenth century, there are in �England writers who attempt to describe the position of the speech-organs for �the production of English phonemes, and who invent what are in fect systems of �phonetic symbols. These various kind of evidence, combined with a knowledge of �the mechanisms of speech-production, can often give us a very good idea of the �pronunciation of an earlier age, though absolute certainty is never �possible.

　　When we study the pronunciation of a language over any period of a few �generations or more, we find there are always large-scale regularities in the �changes: for example, over a certain period of time, just about all the long �[a:] vowels in a language may change into long[e:] vowels，or all the �[b]consonants in a certain position (for example at the end of a word) may �change into [p] consonants. Such regular changes are often called sound laws. �There are no universal sound laws (even though sound laws often rlect �universal tendencies), but simply particular sound laws for one given language �(or dialect) at one given period.

　　It is also possible that fashion plays a part in the process of change. It �certainly plays a part in the spread of change: one person imitates another, and �people with the most prestige are most likely to be imitated, so that a change �that takes place in one social group may be imitated (more or less accurately) �by speakers in another group. When a social group goes up or down in the world, �its pronunciation may gain or lose prestige. It is said that, after the Russian �Revolution of 1917, the upper-class pronunciation of Russian, which had formerly �been considered desirable, became on the contrary an undesirable kind of accent �to have, so that people tried to disguise it. Some of the changes in accepted �English pronunciation in the seventeenth and eighteenth centuries have been �shown to consist in the replacement of one style of pronunciation by another �style already existing, and it is likely that such substitutions were a result �of the great social changes of the period: the increased power and wealth of the �middle classes, and their steady infiltration upwards into the ranks of the �landed gentry, probably carried elements of middle-class pronunciation into �upper-class speech.

　　A less specific variant of the argument is that the imitation of children �is imperfect: they copy their parents’ speech, but never reproduce it exactly. �This is true, but it is also true that such deviations from adult speech are �usually corrected in later childhood. Perhaps it is more significant that even �adults show a certain amount of random variation in their pronunciation of a �given phone me, even if the phonetic context is kept unchanged. This, however, �cannot explain changes in pronunciation unless it can be shown that there is �some systematic trend in the failures of imitation: if they are merely random �deviations they will cancel one another out and there will be no net change in �the language.

　　One such force which is often invoked is the principle of ease, or �minimization of fort. The change from fussy to fuzzy would be an example of �assimilation， which is a very common kind of change. Assimilation is the �changing of a sound under the influence of a neighbouring one. For example, the �word scant was once skamt，but the /m/has been changed to /n/ under the influence �of the following /t/. Greater ficiency has hereby been achieved, because /n/ �and /t/ are articulated in the same place(with the tip of the tongue against the �teeth-ridge), whereas /m/ is articulated elsewhere (with the two lips). So the �place of articulation of the nasal consonant has been changed to conform with �that of the following plosive. A more recent example of the same kind of thing �is the common pronunciation of football as foopball.

　　Assimilation is not the only way in which we change our pronunciation in �order to increase ficiency. It is very common for consonantsto be lost at the �end of a word: in Middle English, word-final [-n] was oftenlost in unstressed �syllables, so that baken ‘to bake’ changed from [ba:k?n] to[ba:k?],and later to �[ba:k]. Consonant-clusters are often simplified. At onetime there was a [t] in �words like castle and Christmas, and an initial [k] in words like knight and �know. Sometimes a whole syllable is dropped out when two successive syllables �begin with the same consonant (haplology): a recent example is temporary, which �in Britain is often pronounced as if it were tempory.

　　题型难度分析：

　　本篇文章还是以细节题作为主打题型，总体难度中等。

　　题型技巧分析：

　　句首配句尾这样的小题型，最近比较热。

　　1)句首是按文章顺序出的，依次定位，句尾打乱顺序，可以提前浏览句尾全部浏览题干。

　　2)根据句尾依次定位，如果句首难定位，则句尾的改写简单，而如果句首易定位，则句尾的改写难。
