Unit 9 It’s important to have good habits. Ⅰ.Section A 课文精讲 1.I think it’s important for teenagers to talk problems over with someone. 我认为对于青少年来说和别人商讨问题是重要的。 该句中it是形式主语,真正的主语是to talk problems over with someone,动词不定式的逻辑主语由for引导。it作形式主语时常用于以下两种结构: It’s+adj.+for sb.+(not) to do sth. 如果前面的形容词是描述不定式这一动作,通常用for引出逻辑主语, 例:easy,hard,difficult,interesting,impossible,necessary,important It’s+adj.+of sb.+(not) to do sth. 如果前面的形容词是描述不定式动作的执行者的品质,则用of 引出。 例:good,kind,nice,clever,foolish,right,brave 例题:It’s necessary you to get along well your classmates. A.of;with B.for;with C.of;to D.for;to 2.Exercising helps teenagers to stay healthy.锻炼帮助青少年保持健康。 (1)exercising是动名词,在句中作主语。 在一般现在时中,当动名词、动名词短语、动词不定式或宾语从句等作主语时,其谓语动词用单数。 (2)句中stay healthy与keep fit 同义。 stay意为“保持”,和keep同义;stay还可表示“待在某地”。 例题: ①保持健康很重要。 is very important. ②I’m going to help my mom (clean) the house. 3.In order to be healthy,teenagers need to get enough sleep. 为了保持健康,青少年需要得到足够的睡眠。 (1)in order to do sth. 为介词短语,表目的,意为“为了做某事”; 其否定形式为in order not to do sth.,意为“为了不做某事”。 (2)enough sleep 意为“充足的睡眠”,enough意为“足够的;足够地”, 修饰n.时,放在名词前后都可;修饰adj.或adv.时,放在所修饰词之后。 例题:①Jim is studying harder get into a better university. A.in order that B.in order to C.so that D.as soon as ②这房子对我们来说不够大。The house for us. 4.They know it is never too late to change bad habits. 他们知道改变坏习惯从来不会太晚。 It’s never too late to do sth. 意为“做某事从来不晚”。 too...to...句型可以转化为not... enough to...和so/such..that...句型,此时that 从句为否定结构。 例:He is too young to do the work. →He is so young that he can’t do the work. →He is not old enough to do the work. 他太年轻了,不能做这项工作。 例题:①他太矮了,够不着树上的苹果。 He is the apples on the tree. ②活到老,学到老。 It is learn. 5.However, Wang Le’s parents trust her because she tells them her problems. 然而,王乐的父母相信她,因为她会把自己的问题告诉父母。 trust 动词,意为“信任,信赖”; 辨析:trust,believe与 believe in trust后面接表示人的名词或代词,指相信某人的能力。 believe意为“相信”,后接表示人的名词或代词,指相信某人所说的话。 believe in指信任某人的品质或某真理等。 例题:I my child that he can do it all by himself. A.believed B.believed in C.trust Section B 课文精讲 1.I need to exercise more regularly. 我需要更有规律地锻炼。 need 动词、名词,意为“需要”。 need的用法: 情态动词: ①一般用于否定句和疑问句中。 ②后接动词原形,即need do sth.。 ③用need提问时,肯定回答用must,否定回答用needn’t。 实义动词: ①主语+need(s)+名词/pron. ②主语+need(s)+to do sth. ③主语+need(s) doing = 主语+need(s) to be done,意为“某事需要被做”。 名词:常用作不可数名词,in need of 意为 ... ...
