whether作为“是否”讲却没有疑问意味 从可行性上进行分析: 我们知道一般疑问句和特殊疑问句,其句子,都是助动词(be,will,could,do等)提前到主语之前了。 把一个陈述句的助动词提前,变成一般疑问句,那么这句话就表示“……是否……?”这样的疑问了。 所以在一般疑问句里,我们不需要whether来表示疑问含义。 那么whether能引导起来特殊疑问句吗?显然也不能,前面有文章说过,特殊疑问词,是代替了原陈述句中的某一因素,缺的是什么,就用what,缺的是人,就用who,缺的是什么人的,就用whose,缺的是原因,就用why,等等。那么whether能代替句子中的什么因素么?显然是不能的。所以它也构成不了特殊疑问句。
whether在现代英语中是连词,用来引导从句。 其意义为“是还是否,不管是不是”, --主句--|||||||| ---从句--- -----主句------|||||||| -------从句---------
================================= 我们知道,一句话说完,就要加句号“。”“.”。 但有很多句子,从语法角度来分析,明明可以看作是两句话,但它们之间却是逗号“,”。这就是因为,这两个句子甚至多个句子之间,联系是紧密的,是围绕着一个事情的。 那么这两个或多个句子它们就叫做并列句、主从句,有从属关系的,就是主从句。没有从属关系,而是表示同一个含义(引申),表示不同含义(转折,选择,对比),表示因果关系的,这样的句子就是并列句。 在语言里,也就有相应的连词,用来连接这样的关系紧密的两个或多个句子。而连词不止连接两个句子,还被用来连接词语或者短语。 引导句子的时候,它们叫做并列连词或者从属连词。只在它们后面跟短语,或仅仅只跟单词,那时候它们就只叫连词,而不是从属连词了。
常见的表示语义引申的并列连词有: and 、 neither…nor 、both…and 、not only... but also 、as well as,它们分别可以对应汉语中的连词: and——“而且,以及”, 1. and Justice is on your side,and justice will triumph over injustice. 正义在你们一边,而正义是会战胜邪恶的。
Go straight on and you'll see a church. 一直走下去你便可以看到一座教堂。
2. neither... nor She could neither speak nor write . 她既不会说,也不会写。 3. both... and A man should have both courage and perseverance.一个人既要有勇气又要有毅力。 4. not only... but also We should not only be bold, but also be cautious. 我们不仅要大胆,而且要谨慎。 5. as well as 不常用 I have read one of his novels as well as a few of his plays. 我读过他的一本小说和几个剧本。 表示选择的并列连词有: or ——或者,否则 either... or——“不是…就是”“或者…或者” 1. or You may do it yourself, or ask someone else to do it. 你可以自己做或者让别人做。 2. either... or I left it either on the table or in the drawer. 我不是把它放在桌子上了,就是放在抽屉里了。 You'll either behave yourself, or you'll never go out with me. 你要么老实点,要么就永远不能跟我一起出去。 除了表示选择外,or和either... or还可以译为“否则”: Now I must go, or I shall be late for the party. 我现在得走了,否则晚会我就要迟到了。 表示转折或对比的并列连词有: yet ——仍旧 1. but He tried hard but he was unsuccessful. 他做了很大努力但没有成功。 2. yet The car was old, yet it was in excellent condition. 这辆车子很旧,但仍处于良好的状态。 3. however I feel a bit tired,however, I can hold on. 我有点累了,但我能坚持下去。
