　　Recent research has claimed that an excess of positive ions in the air can have an ill effect on people‘s physical or psychological health. What are positive ions? Well， the air is full of ions， electrically charged particles， and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm， earthquakes when winds such as the Mistral， Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibres， or from TV sets， duplicators or computer display screens.

　　When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches， fatigue， irritability， and some particularly sensitive people suffer nausea or even mental disturbance. Animals are also affected， particularly before earthquakes， snakes have been observed to come out of hibernation， rats to flee from their burrows， dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.

　　Conversely， when large numbers of negative ions are present， then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea， close to waterfalls or fountains， or in any place where water is sprayed， or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea， or in the mountains with tumbling streams or waterfalls.

　　To increase the supply of negative ions indoors， some scientists recommend the use of ionisers： small portable machines， which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course， there are the detractors， other scientists， who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves， or on others， of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.

2014年6月大学英语六级阅读练习的延伸阅读——英语六级阅读考前必备技巧

 

　　1．语言的障碍。Readingis a comprehensive skill because it concerns the recognition of configuration， pronunciation， grammatical inflexion and the comprehension of words， sentences and paragraphs.（魏立明，孙长顺：2001 ）由于有的单词往往有几种甚至几十种意思，而一个词的确切含义只有在具体的文章之中根据上下文才能确定。因此，词义的转换和搭配仍是阅读中的障碍。所以要避免进入见词就查字典的误区。

　　2．文化背景知识的障碍。因为文化背景知识是阅读的无形障碍。由于不了解英语国家的文化背景，因此有时很难做出判断。People believe that both visual and non-visual information is involved in reading comprehension. As a matter of fact， it seems that the more non-visual information the reader possess， the less visual information is needed.（魏立明，孙长顺：2001 ）。 所以多做泛读的训练将有所帮助。

关于这两个障碍的排除在本文的以下部分中也有较详尽的论述。

3．阅读技巧的障碍。而这一障碍又是多方面的。如找中心思想，推断文章中有没有直接说明的意思，确定作者的语气等。本文将就这一方面进行重点论述。
