2016英语专四语法重点解析(2)

2016专四专八改革,专四语言知识部分总分为20分,题量减了10 题,但分值增加了5分,对专四考生来说是件好事,分值与阅读理解相等。考生们可以在词汇、短语语法知识上多多练习争取不扣分。从近13年的英语专四真题来 看,我们不难发现英语专业四级的语法与词汇考题主要是围绕11项语法要点:从属分句、非限定动词、虚拟语气、情态动词、限定词、句子成分、倒装、动词时 态、附加成分和强调句型。而考试的重点和难点则集中在考核考生对从属分句、非限定性动词、虚拟语气、情态动词和动词时态等语法的应用上。

引导原因状语从句的从属连词有because(因为), as(由于), since(既然), now(that)(既然), when(既然), seeing (that) (由于,鉴于), considering (that)(考虑到), given (that) (考虑到)等。

一、引导原因状语从句的从属连词主要的有because,for,in that,for the reason that;as,seeing (that), seeing as;since;now (that); considering (that)等:The woolly shrank because it was washed badly. 毛衣因为洗涤的方法不好而缩水。I cant get to sleep because of the noise outside. 由于外面声音嘈杂我睡不着。Since [As] weve no money, we cant buy it. 由于我们没钱,我们不能购买它。Seeing that its raining, wed better stay indoors. 既然外边在下雨,我们最好待在室内。Now that you are here, youd better stay. 你既然来了,最好还是留下吧(既来之,则安之)。【注】除以上提到的大家比较熟悉的引导原因状语从句的从属连词外,when有时也可引导原因状语从句(when表示“既然”)I wont tell you when you wont listen. 既然你不想听,那我就不告诉你了。

二、关于notbecause结构该结构中的否定词有时否定主句,有时否定从句,一般要根据句子的意思作出正确或合乎逻辑的理解。
not否定主句,最好在because之前用逗号,否则会引起歧义,如下句在没有特定上下文时就有两种解释:I didnt go because I was afraid. 我没有去是因为怕。/ 我不是因为怕才去的。不过若because之前有just修饰,一般认为not 是否定从句的:You shouldnt get angry just because some people speak ill of you. 你不要因为有人说你坏话而生气。

三、because不能与so连用汉语习惯上说“因为…所以…”,但英语习惯上却不能将 sobecause 连用:因为下雨,所以我们得呆在家里。正:Because it was raining, we stayed at home. / It was raining, so we stayed at home.误:Because it was raining, so we stayed at home.
 
四、because从句与 because of短语的转换Because引导的原因状语从句有时可与because of 短语转换,because of后加的原因可以为好或坏但最正规的还是because
 He cant come because he is ill. / He cant come because of his illness. 他因病不能来。I said nothing about it because his wife was there. / I said nothing about it because of his wifes being there. 因为他妻子在那儿,我对此事只字未提。比较:because, since, asfor1) because语势最强,表示不知道的原因用because,即说话人认为听话人不知道。因此because从句是全句最重要的部分,通常被放置于主语之后。 当原因是显而易见的或已为人们所知,就用assinceI didn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2)for虽然表示原因,但因语气比because弱得多,是可说可不说的话,只能位于主句之后。这时,for是并列连词,如果不是因果关系,而是对前面主语内容加以解释或推断时,只能用forHe is absent today, because / for he is ill.He must be ill, for he is absent today.
