For one week ,she did not do any housework and neither did I.解析：neither/nor+系动词be/助动词/情态动词+主语，“也不”倒装结构，表示前面的否定情况也适用于后者。e.g.: He doesnt like smoking and neither does I. Lily cant speak English and neither cant Tom. Ann isnt a student and neither am I.neither+可数名词单数，“两者都不”，做主语是谓语动词用单数。此时neither是形容词；Neither answer is right.neither of“两者都不”，可做宾语或主语，此时neither是代词；e.g.：Neither of my parents know(s) English.neither.nor.“既不也不”，连接主语时，谓语动词就近原则。e.g.: Neither my father nor I am interested in the movie.Neither I nor my father is interested in the movie.so+系动词be/助动词/情态动词+主语，“也是”。3. as soon as.=the minute (that).=the moment (that)“一就”，后接时间状语从句；主将从现或主从句时态一致e.g.：He left as soon as he heard the news.=He left the minute he heard the news.他一听到消息就离开了。 I began to make dinner as soon as I got home.= The minute I got home, I began to make dinner.4. borrow sth. from sb.=borrow sb. sth.从某人那里借某物（主语从别人那里把东西借来）lend sth. to sb.=lend sb. sth.把某物借给某人（主语把自己的东西借出去）keep：“保存”引申为“借”，与一段时间时间状语连用口诀:主语“借出”是lend，主语“借入”是borrow。若连一段时间用，要想“保存”用keep。5.finish doing sth.完成做某事【拓展】能跟动名词作宾语的动词或短语：避免、错过、少延期；(avoid,miss,putoff)建议、完成、多练习；(suggest,finish,practise)喜欢、想像、禁不住；(enjoy,imagine,canthelp)承认、否定、与嫉妒；(admit,deny,envy)逃避、冒险、莫原谅；(escape,risk,excuse)忍受、保持、不介意。(stand,keep,mind)6. when 和while同：均可用作连词，引导时间状语从句，意为“当的时候”区别：when：从句
