1、陈述句中有肯定句与否定句之分。其中可以分为以下五种： 主语+不及物动词。如：I arrived at six last night. 主语+及物动词+宾语，如：I bought a good English?Chinese Dictionary yesterday. 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. 主语+及物动词+宾语+宾语补足语，如：I found it impossible to do it. Please
2、 keep the classroom clean and tidy. 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
3、相呼应。要注意的有如下几点： 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。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)。 有量词时应按量词的数量计算；如： This pair of glasses is good? My glasses are broken. 有
4、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 policewomen? 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
5、 but also， neither 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 didnt 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
6、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。 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
7、不是宾语，所以在口语中常常被省略。如： I am sure (that) she has passed the exam? if, 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 not? what 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 dont 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)。 who，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 looking for? whose 如： I want to know whose book this is? which 如： Do you know which book is mine?
