get 用法的疑問
我們知道使役動詞let make have后面跟動詞不定式要省略to,但get卻有時候省略,有時候不省略：
get＋賓語＋不定式
Can you get us to do the experiment?
He couldn't get the car to start and went by bus.
再看這里的例子：
Our teacher get us students finish our homework.
He get his body lie on the ground because he is tired.
這個句子憑語感的話加個to感覺別扭：
My daughter's fifth grade teacher got every child in her class feel special
這兩個似乎不加也合適,但原句是有to的.
He got his sister TO help him with his homework.
You will never get him TO understand.
請問get這個詞到底怎么回事.
1、它算是使役動詞嗎?
2、為什么有時候和let have make用法一樣,有時候不一樣.為什么有時候加to,有時候不加?
3、到底什么時候該加to,什么時候不該加to?
誰能給一個比較權(quán)威的解釋.
回復(fù)mlars：Can you get us to do the experiment?這個似乎可以用let替換，let 肯定不要to，為什么一定要用have才行？
help 也是可加to可不加to，但這個是公認(rèn)的，而get卻很疑惑。
