“说”，也称“杂说”，是文言文的一种文体，属于文学性杂感性的论说文，目的在于说明一个道理。刘勰说“说者说语”，明代吴讷等人引证字书说：“说者，释也，述也，解释义理而以己意述之也。”从大量的“说”体文章来看，的确可以这样说：“说”者，说说谈谈之谓也，“杂说”就是“杂谈”。它的内容广泛，可就一事、一物、一景生发开去，为之一说；它的形式多样，可记叙、描写、议论、抒情；可以议论为主，“与论（即议论）无大异也”，也可以记事、写景为主，写得与抒情散文难以分辨，或者与杂文、小品文类似。但其形式无论如何自由，其目的都在于说明道理。这是“说”的一个鲜明特点。如南宋林景熙的《蜃说》，绝大部分篇幅是对蜃楼幻景的描写，但其最终目的是以蜃楼为喻，说明人世繁华像海市蜃楼一样虚幻，瞬息即逝，从而抒发对宋朝覆亡的慨叹。《爱莲说》也是这类文章，貌似描绘莲的形象，赞美莲的品格，实则借说明爱莲的原因进而说明当时世俗的污浊，抒发作者不与世俗合流而洁身自好的情操。它将记叙、描写、抒情、议论融为一体，似以记叙描写为主，但又无处不是在说明、议论和抒情。“予独爱莲之……”一句便是突出的例证。
“说”来源于战国策士的游说之词，为能打动读者，使其因有所领悟而心情愉悦，它重技巧，尚文采，陆机说的“说炜晔而谲诳”，刘勰说的“言咨悦怿”，“喻巧而理至”，“飞文敏以济辞”等语就是这个意思。这是“说”的又一特点。因此，它是具有文学色彩的论说文。
文言文中的“说”这一文体的发展大体可以《文心雕龙》为界分为两个阶段。其前，限于谈论政治，解释经义；其后，特别是唐宋以来，内容有了重大突破，涉猎到社会生活和自然现象的各个方面。人们所称谓的“说”主要是指后者。清末林纾认为《马说》和《捕蛇者说》是“说之变体”，就表明了这一突破和发展。现代的杂文、小品文以及说明文就是由“说”发展演变而来的。“说”与这些文体有共通之处，但不应将它们混同起来，因为它们是属于不同历史范畴的概念。不能把“说”称为杂文的另一个原因是：古今杂文的概念有所不同，在古典文学中杂文是与“说”等文体并立的一种文体，是指“说”等文体之外的杂著，即杂体文章。

阅读理解。
Upon reaching an appropriate age (usually between 18 and 21 years), children are encouraged, but
not forced, to "leave the nest" and begin an independent life. After children leave home, they often find
social relationship and financial support outside the family. Parents do not arrange marriages for their
children, nor do children usually ask permission of their parents to get married. Romantic love is most
often the basis for marriage in the United States; young adults meet their future spouses (配偶) through
other friends, at jobs, and in organizations and religious institutions. Although children choose their own
spouses, they still hope their parents will approve of their choices.
In many families, parents feel that children should make major life decisions by themselves. A parent
may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do exactly the opposite of what their parents wish in order to be independent. A son
may decide not to go into his father's business on purpose because of a fear that he will lose his
autonomy(自主) in his father's workplace. This independence from parents is not an indication that
parents and children do not love each other. Strong love between parents and children is universal and
this is no exception in the American family. Coexisting (共存) with such love in the American family are
cultural values of self - reliance and independence.
