1stop from doing sth 还是stop doing sth?2为什么must can等情态动词还有still后+be而不是am is are
still是情态动词吗

1stop from doing sth 还是stop doing sth?2为什么must can等情态动词还有still后+be而不是am is arestill是情态动词吗
stop+宾语+ from doing sth /stop +宾语+doing sth 意思一样.其中from可以省略.
但说stop from doing 意思是阻止做.；stop doing sth 意思是停止做某事.
must ,can 等情态动词后跟动词原形,be是am ,is ,are 的原形.

1stop sb from doing sth 阻止某人做某事stop doing sth停止做某事
2must can等情态动词后+动词原形，所以不会是am is are，still不是情态动词，后面不一定+be，

你说一样吗：
1 stop sb from doing sth-------阻止某人做某事
2 stop doing sth------停止做某事
3 I am sure she is watching TV at home== She must be watching TV at home.
must / can / 任何情态动词后面的动词都必须是原型...

2 stop doing sth------停止做某事
3 I am sure she is watching TV at home== She must be watching TV at home.
must / can / 任何情态动词后面的动词都必须是原型，am, is , are 不是动词原型，如果它们的前面有任何情态动词，am, is , are 就必须变成原型。
又如：she is at home如果加may,就成了：she may be at home.
