    There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.

    By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.

    The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.

     听力除了掌握正确的语音和各种考试技巧外，基本的单词短语也是非常重要的。听力中的单词短语基本上属于口语中的，和阅读词汇中有所不同。考生要把历年考题中的重要单词短语和特殊表达法烂熟于心，考试时才能有足够快的反应，因为对话和短文都是只放一遍的。另外，平时最好多做一点听写练习，注重每个单词的拼写，这样考试时才不至于出现听懂了却写错的情况。推荐一些好的听力材料，如toefl和new concept english等。

　　阅读在几乎任何的英语考试中都占有极其重要的地位，它的重要性再怎么强调也不过分。首先请考生注意一点： 做一些模拟题是可以的，但一定要把主要的精力放在历年的真题上。因为真题是最具有权威性的，代表了出题者的一贯思路。而这恰恰是众多考生忽视的。很多考生把真题草草做过一遍就扔在一旁，没有全面透彻地理解这些文章。考生要从词汇，难句，语篇和出题点四个层次对真题进行精读，平时再多读一些英文报纸杂志，阅读水平一定会得到实质性的提高。尤其要强调的一点是：真题中的重点单词短语一定要牢记。

　　词汇题虽然只有15分，但也是很多同学头疼的题目，要么做的很好，要么动辄扣八九分以上。六级大纲中的词汇虽然只有一千多个，但都要求复式掌握，也就是要掌握单词在不同的语境中不同的意思或用法，这就是难点。考生要从惯用法，搭配，与同义词，近形词的区别，反义词等等各个方面全面地掌握词汇，这样在考试时才能够从容应对。另外，词汇题考的词汇也有不少是四级就应该掌握的，而这些词汇在六级大纲中就不会有，这就需要考生不能荒废了四级词汇，要打好基础。就词汇题而言，全真题也非常重要，很多词汇每年的复现率很高，全真题中的词汇在各位考生备考时应该首先掌握，重点掌握。

　　完形填空实际上考的就是考生的阅读能力，以及对搭配，单词辨异的掌握等。综合改错和作文可以归到一类中，两者都考查了考生的写作能力，只不过作文更直接一点。改错中的很多错误其实就是很多学生在平时写作时经常犯的错误。比如说意义形式容易混淆的词，搭配错误的词，词性，时态，语态，数，格等方面的错误。可以说，改错考查了考生的综合能力。除了掌握一些应试技巧外，考生应在自身语言基本功，尤其是语言的准确使用方面提高自己。

　　写作除了学会一些写作套路以外，考生也要注意掌握各种词汇，句型的不同表达，丰富自己的表达方式。平时学到的词汇，句型要尽量学会使用，看到好的表达法就背下来。只有足够的输入，考试时才会有高质量的输出，到了评卷老师那里你的作文才不会千篇一律，才有亮点，才有加分因素。
