Grammar and usage—语法·提升语言能力 语法项目——简单句、并列句和主从复合句 初识语法——在美文运用中体悟　 　　　　　　　　　　　　　　　 Habits, whether they are good or bad①， are gradually formed. When a person does a certain thing again and again②， he'll be obliged to do it in the same way by some unseen force. Thus habit is formed③. Once a habit is formed④， it is difficult and sometimes almost impossible to get rid of it. Therefore, it is very important that we should take care in the formation of habits⑤. Good habits have many advantages, such as going to bed early and getting up early which makes us healthy⑥. Diligence helps to succeed. If we form bad habits, such as rudeness, laziness, lying and stealing⑦， we might be mined by them. Keep away from bad habits and we'll acquire good habits for ourselves and others⑧. ①句是whether引导的让步状语从句； ②句是when引导的时间状语从句； ③句是简单句； ④句是once引导的条件状语从句； ⑤句是that引导的主语从句； ⑥句是which引导的定语从句； ⑦句是if引导的条件状语从句； ⑧句是and连接的并列句。 慧学语法——在归纳演绎中学通　 按句子的结构分类，英语句子有三大类：简单句、并列句和主从复合句。 一、简单句　 [先感知] ①(教材P16典句)Teenagers' physical changes may result in such family tensions. ②(教材P16典句)Heated arguments and cold silences are common between teenagers and their parents. ③In a sense, it doesn't matter any more. ④He gave the very interesting comic book to his sister. ⑤He will keep the room clean at all times. [会发现]　 以上句子都是______，它们只有一个主语(或并列主语)和一个谓语(或并列谓语)。 简单句 4 [明规则] 1．简单句就是只包含一个主谓结构的句子。但是有时两个或更多的并列主语拥有一个共同的谓语，甚至并列有两个主语和两个谓语，这样的句子仍然是简单句。 2．简单句中句子各成分都是只由单词或短语构成的。 3．在简单句中主谓结构是句子的主干，是句子的核心。 4．简单句可归纳为五个基本句型： (1)主语＋谓语； (2)主语＋连系动词＋表语； (3)主语＋谓语＋宾语； (4)主语＋谓语＋宾语＋宾补； (5)主语＋谓语＋间接宾语＋直接宾语。　　 [对点练]　(完成句子) ①He often ______________ in the morning. 他常常在早晨读英语。 ②________________ American boys. 汤姆和迈克是美国男孩。 ③She ______________and often _______________for the wall newspapers. 她喜欢画画，并常为墙报画画。 reads English Tom and Mike are likes drawing draws pictures 二、并列句　 [先感知] ①(教材P17典句)Unfortunately, your parents do not always agree and that makes you feel unhappy. ②(教材P20典句)There is a lot to see, so take some time to look around our website! ③W
