第二篇句法
一、主要句式
(一) 知识概要
初中所学的句型一般要分为陈述句、疑问句、祈使句和感叹句。陈述句中有肯定句与否定句之分。其中可以分为以下五种:① 主语+不及物动词。如:I arrived at six last night.② 主语+及物动词+宾语,如:I bought a good English Chinese Dictionary yesterday.③ 主语+及物动词+间接宾语+直接宾语,如:Please tell me a story before I go to bed. 这样可加双宾语的句子有buy,tell, give, ask, pass, teach.④ 主语+及物动词+宾语+宾语补足语,如:I found it impossible to do it. Please keep the classroom clean and tidy.⑤ 主语+系动词+表语,如:Tom is an American boy. The grass turned green in spring.在初中常见的句型中有There be…句型,表示存在某种事物,如:There is a map on the wall其be动词的形式要与其后面相近的那个名词相一致。要注意的是这种句型加入助动词后,也要保持be动词,不要换用have,如:There is going to be a meeting tomorrow.在句子结构中要注意主谓一致的问题,即句子的主语与谓语动词要相呼应。要注意的有如下几点:① 用and连接两个主语时一般应视为复数,但如一人身兼两职时则要用单数谓语动词形式,如:A singer and dancer is coming to our party. a singer and dancer 既歌唱又可舞的演员。而 a singer and a dancer 则要译为:一位歌唱家和一位舞蹈家。②有些以 s 结尾的名词谓语动词要用单数,如: The news is good (news 为不可数名词)。③ 有量词时应按量词的数量计算;如: This pair of glasses is good My glasses are broken.
④有些形单却意为复数的名词,如: People are coming here这样的词还有 Police,如果要讲一个警察时,应讲 a policeman。两个警察为 two policemen。又如 a policewoman, two policewomen⑤所有不定代词 each, either, neither, one, the other, nobody, nothing, anyone, anything,someone,something … 要作为单数如: Someone is waiting for you在并列句中表示联合关系的连词有:and not only … but also,ne ither … nor,either … or如: My sister and my parents are going to the cinema。表示转折关系的并列连词有: but 和 yet,如: She is a good student, but she didn't pass the final exam. 又如: I think the news is strange, yet it is true表示选择关系的连词有:or,either … or,如: Hurry up, or you will be late for school表示因果关系的并列连词有: for, so 如: They studied very hard, so they all passed the exam
在初中范围复合句中主要有状语从句和宾语从句(名词性从句)两种,而定语从句(形容词性从句)要在高中讲述,为了使同学阅读文章方便,我们将在下面另一章予以介绍。我们首先来看宾语从句。①在及物动词的后面可以接一个名词来充当宾语,如: I knew the man, 而这时也可以用一个句子来充当宾语,如:I knew that he was a good man这时宾语从句的连接词有 that, (that 只在从句中起联接作用,不
在句中充当语法成分,既不是主语也不是宾语,所以在口语中常常被省略。如: I am sure (that) she has passed the exam②if, whether 它们在宾语从句中只起连接作用,不起语法作用,当作是否讲。从句中有 or not 结构时,要用 whether, 如: I ask him if (whether) he has had his lunch I asks him whether he has had his lunch or not③what 它在宾语从句中除了作连接词外,还要作主语或宾语成份,如: I don't understand what you said(what 作 said 的宾语)。又如: I asked him what made him sick (what 在宾语从句中作主语)。④who,它也和what一样,在句中除作连接词外,可以充当句中的成份,如:I know who she is lo oking for? ⑤whose 如: I want to know whose book this is? ⑥which 如: Do you know which book is mine?在连接词中还有4个常用的连接副词,①how 它的应用最广,如:how much, how many, how long, how soon, how old …。如: How much does it cost? ②when 它只是连接时间状语,如: Please tell me when the mee ting will begin? ③where 它连接地点状语,如:Where are you from? ④why 它要连接的是原因状语从句,如: The teacher asked why Tom didn't come to school. 在考试中常见到的考点是:宾语从句的时态与主句时态的呼应问题。
①主句谓语动词如果是现在时或将来时,宾语从句的时态可以是任何所需要的时态,如: I know he didn't come. 我知道他没来。 I know he will come tomorrow我知道他明天来。I know he has gone to London我知道他已去伦敦了。②主句中的谓语动词若是过去时,宾语从句也要用过去时态中的某一种。比如:一般过去时,过去进行时,过去将来时,过去完成时。除了在表达宇宙中的客观真理时,不能用现在时态。如: I wanted to know when he would come The teacher told me the earth moves around the sun状语从句主要有时间状语从句,其连接词有:after, before, when, as, as soon as, until (till), while, since, by其中较难掌握的有以下几点:①until (till) 直到,在用 until 表达时间状语的句子中,主句中的动词是要十分小心去选择。如动词是持续性动词,它要用肯定句,如: I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词,则要用否定句,如: He didn't go to bed until his mother came back②由since, for, by, before 来引导的时间状语从句。 since 引导的时间状语是动作的开始时间,如: I have studied English since 1990而由 by 引导的时间状语通常是动作的结束时间,如: I had learned 25 English songs by the end of last term而before 则多用于完成时, ago 则多用于一般过去时,如: He had finished his work before twelve yesterday I left my hometown two years ago③在状语从句中用一般现在时或一般过去时表示将来。它们可能是主句用一般将来时,从句用一般现在时,如: If it rains, they won't go to the park on Sunday也可以主句是一般过去时,从句用一般过去进行时,如: He said if it rained the next day he would not go to the park考试中常见的考点有:要学生区别是条件、时间状语从句还是宾语从句,因在宾语从句中该用什么时态用什么时态,如: I want to know if he will come here tomorrow在宾语从句中的条件状语从句与主句的关系,如: I want to know if it rains
