关于will/shall+不定式进行体和be going to+不定式和be+ing（现在进行体）

关于will/shall+不定式进行体和be going to+不定式和be+ing（现在进行体）
语法书上说will/shall+不定式进行体表示自然要发生的含义,be going to+不定式表示意图和预见,be+ing意义是表示按计划,安排即将发生的动作,常用于位置转移的动词,如go come leave start arrive等,在做这练习时,错得有点惨不忍睹,求高手答疑,部分练习如下：
1 I _(take)the carpet to the cleaner.
am going to take
本人认为是：am taking
2 I_(start)building my garage.
am going to start

3 I (send) him to a day school.

4 He _(give) a lecture on Friday and is attending a big reception on Sunday.
