17、义：只有一个主语（或并列主语）和一定义：只有一个主语（或并列主语）和一个谓语（或并列谓语）。个谓语（或并列谓语）。lHe often reads English in the morning.lTom and Mike are American boys.lShe likes drawing and often draws pictures for the wall newspapers.l 我们可以给句子的动词加上副词修饰，给名词加我们可以给句子的动词加上副词修饰，给名词加上形容词、介词短语修饰，给句子加上状语进行上形容词、介词短语修饰，给句子加上状语进行修饰等，以使整个句子的意思变得更加的

18、丰富和修饰等，以使整个句子的意思变得更加的丰富和充实。但不管如何变，都充实。但不管如何变，都只有一个主谓结构只有一个主谓结构。l He worked hard all his life.(划线部分在句中作划线部分在句中作状语，修饰动词状语，修饰动词worked)l He is a school student in No.1 Middle School.(划线部分在句中作定语，修饰名词划线部分在句中作定语，修饰名词student)五大句型 英语句子看上去纷繁庞杂，但仔细观察不外乎五个基本句式。这五个基本句式可以演变出多种复杂的英语句子。我们常说的五大句型就是指的简单句的五种类型。换言之，绝大多

19、数英语句子都是由这五个基本句式生成的。1.Things changed.主 +谓2.Trees are green.主+系+表3.We dont beat children.主 +谓 +宾4.He gave his sister the piano.主+谓+间接宾语+直接宾语5.I found the book easy.主+谓+宾 +宾补（二）（二）.并列句并列句l由并列连词连接、含有两个或更多主谓结构的句子叫并列句。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。l句型：简单句+并列连词+简单句lYou help him and he helps

20、 you.lThe future is bright;the road is tortuous.一、表示转折对比关系的并列连词l 1.but但是，可是，而，却l 连接两个简单句，有时句中某些词可以省略；连接两个并列成分，可以放在一个句子的句首，后面不接逗号。l 例：I hope you dont mind me asking，but where did you buy those shoes？l 2.yet但是；尽管如此l 可连接两个句子，用逗号分开，也可在yet 前加and，还可以放在一个句子的句首。l 例：The car is old，yet it is in good condition

21、.这辆车旧了，但车况很好。l3.while而，但是，可是，却lwhile 作连词用时，可表示对比或转折关系。I do every single bit of housework while my husband Bob just does the dishes now and then.二、表示因果关系的并列连词l1.for因为l由并列连词for 引导的分句常置于句子后部，而且常用逗号与前面的分句隔开。for 分句主要是对前一分句补充说明理由或推断原因。for 分句不能用来回答why 问句。l例：I did my best not to show pleasure，but what I was

22、 feeling was pure happiness，for my words had the power to make people laugh.l2.so 因此l可以连接两个句子，中间有时用逗号隔开；也可在so前加and；还可以放在一个句子的句首。l例：The shop doesnt open until 11 a.m.，so it loses a lot of business.三、表示选择关系的连词orlor连接并列成分时，意为“或者，还是”；用于否定句中，意为“也不”，这时不宜用and；还有“否则，要不然”之意，相当于otherwise.l例：Would you like a c

23、up of coffee or shall we get down to business right away？lWork hard,or you will get nothing.四、表示并列关系的并列连词l1.and和，同，与，又，并且l例：Stand over there and youll be able to see it better.l2.not only but also 不仅而且l例：Not only I but also Jane and Mary are tired of having one examination after another.l3.neither n
