1,You are so kind to repair my bike.不定式短语做什么成分 形式上,逻辑上.you 是主语还是不定式是.
答：
A,不定式做状语,这里不存在形式主语,形式宾语.因为没有it.
不定式做真正主语例如：
it is hard to learn english.= to learn english is hard
而You are so kind to repair my bike.却无从转换
因此 you是主语
2、The book is easy enough for you to read.划分句子成分
for you 做的是 to read 的逻辑主语,可以看做是状语,也可以和to read 放一起做状语.
答：
记住 主语+系+表 除了这几个成分“其他的都是状语.”
如：he is happy.主语+系+表
he is happy to go to school
he is happy to go to school with TOM
he is happy to go to school with TOM at 8:00
后面全是状语 除了he is happy.
3,most festival would celebrate the end of cold weather,planting in spring and harvest in autumn.planting和harvest 时态怎么不一样呢?
答：plant 本身是没有名词的,但是这个地方需要名次,所以就变成了动名词,就像前面的名次end 一样,而harvest本身是个名词,根本就不用加上ing.
