黑暗版阅读真题解析1997Text 2

难句解析：

①There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet it is an observation made so frequently that it deserves comment.
▲第一个句子使用了there be句型，其中of course是插入语。第二句是主语+系动词+表语结构。第三句话中使用了so... that结构：其中made so frequently是过去分词作定语，修饰前面的observation。
△第一句中的of course作插入语，用逗号与句子的其它部分分开，在开始阅读的时候可以不看。注意第二句话中使用了双重否定表示肯定：hardly unknown等于pretty well-known。另外注意so... that结构的用法：太......以至于。另外observation这里的意思是"因观察而得出的意见"。另外it deserves comment中的it指代前面的observation。

②Strangers and travelers were welcome sources of diversion, and brought news of the outside world.
▲句子的主干结构是Strangers and travelers were... and brought...。
△注意diversion在这里的含义是"解闷，取乐的事情，消遣，娱乐"，而不是"转移，转向"的意思。

③Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest cabin or settlement.
▲这是一个简单句。traveling alone是现在分词作定语修饰前面的someone，if hungry, injured, or ill...实际上是简略的if引导的状语从句，相当于if (he is) hungry, injured, or ill，这里作插入成分。另外have sth.+动词不定式，这一结构中的动词不定式通常是相当于定语部分，修饰前面的sth.，这里就是：没有可以投靠（to turn to/动词不定式）的地方（nowhere/sth.）。
△注意turn to这里的引申含义是"投靠，求助于，求教于"的意思。

④It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers.
▲句子的主干结构是It was not a matter of choice... or merely a charitable impulse...，是主语+系动词+表语的结构。表语由并列的两部分组成，由or来连接。
△on the part of相当于前面的for，意思是"在......方面，对......而言"。

⑤The casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition.
▲这个句子的主干结构是The casual friendliness should be interpreted neither as A nor B, but as C，使用了被动语态。其中neither... nor...结构后用的是同样词性的成分：形容词superficial和artificial。
△注意neither... nor... but结构的使用：既不是......也不是......而是......，重点在but之后。as the/a result of：作为......的结果，由于......而......。

⑥As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships.
▲句子的主干结构是... cultural signals, assumptions, and conventions underlies... interrelationships。
△注意as在这里是一个代词，表示"这一情况，这一事实"。可以参考以下的例句来理解as的用法：The night had turned cold, as is usual around here.夜晚变得很冷，在这一带经常如此。
