Language Points:
1. I thought about it as I walked to and from school. 当我上学和放学时我都在考虑它。
【用法when, while, as 都可引导时间状语从句。这几个词都可以表示“当……时候”，当它们引导的从句的谓语动词是延续性的，三个词可以互换。其中when的用法最广，既可以表示比从句早或晚的动作，也可以表示与从句同时进行的动作，可以指时间点，也可以指时间段；并且它可以与短暂性动词连用。as 表示与主句同时进行的动作，指时间点时可以与when互换。while 只指时间段，引导延续性动作；如表示与主句动作同时进行时，可与when, as 互换。
【举例】①When (As, While) he talked on, he got more and more excited.他越谈越激动。 （这句话中的主句和从句动词动作同时进行，表示时间段）②He hurried home, looking behind as he went. 他赶紧回家，一边走一边往后看。 （主句和从句动作平行，表示时间段）③While the child was playing with his toys, his parents were reading. 孩子在玩玩具，他的父母在看书。(表示时间段，主句和从句都是同时进行的表示延续的动作)
2. I told them that you made it for me. 我告诉他们这是你给我做的。
【用法】某些及物动词后面可以加两个宾语，一个表示人，叫间接宾语；一个表示物，叫直接宾语，它们和在一起称作双宾语。双宾语在句子的位置有两种：
主语 + 及物动词 + 间接宾语 + 直接宾语
主语 + 及物动词 + 直接宾语 + 介词 to 或 for + 间接宾语
如果把间接宾语放在直接宾语之后，间接宾语前就应该加介词to或for。这里加to 或for与动词有关，能够加to的动词有：give, show, send, bring, read, pass, lend, leave, hand, tell, return, write, throw, promise, refuse, sell, take, teach, call, wish等。能够加for的动词有：make, buy, do, get, play, order, sing, dance, cook, pay, build, fill, find, prepare, save, win等。
【举例】①He will make me a new kite. = He will make a new kite for me. 他要给我做一个新风筝。②Grandpa often tells us stories. = Grandpa often tells stories to us. 爷爷经常给我们讲故事。
