1、Section B(2a-2e),任务: 阅读教材2b, 完成下面表格,1.It is the parents job to provide a clean and comfortable environment at home for their children. 在家中给他们的孩子提供一个干净、舒适的环境是家长们的事情。 剖析 (1)此句为“It is+n./adj.(+for sb.)+to do sth.”结构, 意为“(对某人而言)做某事”。 Its dangerous for children to cross the busy street. 对孩子们来说, 穿过繁忙的街道很危

2、险。 【温馨提示】此句型中, 若形容词为kind, nice, wise, brave, stupid, clever, foolish等表示人物的性格、品德及主观感情或态度的形容词, 则后面用of sb.。 Its very kind of you to help me. 你帮助我真是太好了。,(2)provide作及物动词, 意为“提供, 供给, 供应”, 常与介词with连用, 构成provide sb.with sth.意为“提供给某人某物”; 亦可用于provide sth.for sb.结构, 意为“为某人提供某物”。 The sun provides us with light

3、and heat.=The sun provides light and heat for us. 太阳给我们提供光和热。,2.Children these days depend on their parents too much. 当今的孩子太依赖父母了。 剖析 (1)depend意为“依靠, 依赖”, 为不及物动词, 后接宾语时应与on或upon连用。 Your success depends on whether you work hard or not. 你的成败取决于你是否努力工作。 (2)too much相当于一个副词, 修饰动词短语depend on, 放在后面作状语, 意为“

4、太多”。 She worried too much.她过于担心了。,辨析 too much, much too与too many,一言辨异 He is much too fat because he eats too much meat and too many sweets every day.他太胖了, 因为他每天吃太多的肉和糖。,3.Doing chores helps to develop childrens independence and teaches them how to look after themselves. 做家务帮助培养孩子的独立能力, 并教会他们怎样照顾自己。

5、剖析 look after意为“照看, 照顾”, 其同义短语为take care of。 She is old enough to look after/take care of herself. 她足够大了, 可以照顾自己了。 拓展 若表达“好好照顾某人”, 则用take good care of sb.或look after sb.well。 Take good care of yourself and youll feel better soon.=Look after yourself well and youll feel better soon. 好好照顾自己, 不久你就觉得好多了

6、。,【温馨提示】take after, take care与look after, take care of看似相近, 但含义大相径庭。take after意为“(外貌或行为)像”; take care意为“小心, 当心”, 多用于祈使句。 He takes after his father.他长得酷似他父亲。 Take care!There is danger ahead.小心!前面有危险。,4.The earlier kids learn to be independent, the better it is for their future. 孩子们越早学会独立, 对他们的未来就越好。

7、剖析 此句为“the +比较级+., the +比较级+.”结构, 意为“越, 就越”。第一个“the +比较级+.”相当于一个条件状语从句; 第二个“the +比较级+.”相当于主句。the用在形容词或副词的比较级前。 The more he gets, the more he wants. 他得到的越多, 想要的就越多。 The more she learns, the more she wants to learn. 她学的越多就越想多学。 拓展 “比较级+and +比较级”结构表示“越来越” Summer is coming, so the weather is getting hotter and hotter. 夏天来了, 所以天气越来越热。,
