6here are some of the findings of a survey about hopes and dreams ,where thousands of students across china took part in 为什么用where
说清原因,到底为什么

1.to do
不定式表示目的或打算,它与doing的区别是：doing一般为习惯性或经常性动作,to do 则表示偶然性,另外to do常暗含事情还没有做的意思
2.need to
need为实义动词时,肯定need to do 否定don't need to do
need为情态动词时,肯定need doing（主动形式表被动含义）
否定needn't do
注意绝无need do 形式
3.he runs fast
fast仅表示速度快
quickly表示反应快,行动上迅速敏捷不耽搁或思维敏捷
4.不可以 后面的how to study is best是有问题的,不知道你想表达什么意思
5.可以的 不过不知道前面回答not now有没有问题...
6.首先从句中不缺成分,也就是说从句是一个完整的句子,所以要用关系副词而不用关系代词
关系副词有when表时间where表地点why表原因,一看此处跟时间原因都没有关系所以用where就行了.不过如果你想打破沙锅问到底的话：
where引导定语从句所修饰的名词,不仅可以是具体的地点名词,还可以是抽象名词,相当于介词+which,表示“在这点上”“在这种情况下”等等 如You reach a point where medicine can’t help.（你已到了药物无法治疗的地步） 和你熟悉的句子He sold the house in which he lived 如果没有in 则为the house where he lived是一个道理
再挖掘的话就是高中水平了

二、where定语从句修饰抽象名词case
