六年级上册重难点1.注意由when, if, after引导的状语从句的语法现象：:注意可有两种方法表达：先主句或先从句：I want to be a teacher when I grow up. (主从句之间不用“，”号) 主句 从句When I grow up, I want to be a teacher. (主从句之间用“，”号) 从句 主句同样：You can pick some apples or oranges from the threes if you want. 主句 从句If you want to some apples or oranges, you can pick some from the trees. 从句 主句I feed our chickens after I finish my homework. 主句 从句After I finish my homework, I feed our chickens. 从句 主句(2) 如果从句是将来发生的事，动词用一般现在时表示，例如：I will not go out if it rains tomorrow.Ill tell him about that when I meet him tomorrow.She is going to clean my house afar she finishes her homework.(3) Because 也是状语从句，表示原因：He never feels tired because he has plenty of exercise.(4) After breakfast I ride my bike to school. It takes 40 minutes. 这句话的是“放学后，我骑自行车回家。骑自行车回家花了我40分钟。如果我们把“骑自行车回家花了40分钟”这句话完整地说是：It takes 40 minutes to ride a bike to school. 同样的例句：It usually takes an hour to get there. 到那里花一小时。It took me half an hour to finish the work. 完成着工作花了我半小时。（5）本教材有不少反义疑问句的句子，要求知道其意思： She is hungry, isnt she? 她肚子饿了，不是吗？ He likes the book, doesnt he? 他喜欢那书，是不是？ You often take exercise, dont you? 你经常锻炼身体，是吗？ My hair was very long then, wasnt it? 我的头发那时候很长，是吗？（6）、I see somebody doing something. 我看见某人在做某事。例如： I saw the children playing games.
