语言能力1.掌握构词知识
3.积累高频词块(1)earn a nursing degree 　获得护理学位　 (2)set aside 　留出　 (3)pay her tuitin 　支付她的学费　 (4)supprt her family 　养家糊口　 (5)achieve her gal 　实现她的目标　 (6)bear fruit 　取得成果,成功　 
4.赏析续写佳句“Sme nights my heart was breaking t have t pick between my kids and studying fr exams r papers,” she says.她说:“有些晚上,我不得不在我的孩子和准备考试或论文之间做出选择,　我的心都碎了　。” 
5.破解复杂句式(1)After high schl,Jennifer attended a lcal technical cllege,wrking t pay her tuitin,because there was n extra mney set aside fr a cllege educatin.分析:本句是一个主从复合句。主句主语是Jennifer,谓语动词是attended,wrking t pay her tuitin为现在分词短语作　伴随状　语;because there was n extra mney set aside fr a cllege educatin为because引导的　原因状　 语从句,该从句中set aside fr a cllege educatin为过去分词短语作后置定语。 译文:　高中毕业后,詹妮弗上了当地的一所技术学院,她靠打工来支付学费,因为没有多余的钱供她上大学。　 
(2)She decided t g back t cllege t advance her career and t be able t better supprt her family while ding smething she lves:nursing.分析:本句是一个主从复合句。while ding smething she lves为　状语　从句的省略,she lves为省略关系代词that的定语从句,修饰先行词smething。 译文:她决定回到大学提升自己的职业生涯,并且能够更好地养家糊口,同时做她喜欢的事情:护理。
