这里应该是现在分词形式作为目的伴随状语
The old man devoted all his money to this school ,enabling these students to have a better study environment.
老人把所有钱都捐了,伴随着他希望让孩子有更好学习环境这一目的。
例如The students entered the classroom, following the teacher.
也是现在分词作伴随状语,表示学生是怎么进去的,是伴随着一个怎样的状态进去的
而且当动作是主语主动发出的,用Ing形式,是被动的,用ed形式
the teacher entered the classroom, followed by the students. 被跟着
in order to, to do sth。 so as to do sth. 都表示目的
一般如果是出现在句中的,都是没有逗号的
The old man devoted all his money to this school to enable/ in order to enable / so as to enable these students to have a better study environment.
而当放在句首时,是有逗号的
In order to enable/ To enable these students to have a better study environment, the old man devoted all his money to this school . (so as to只能放句中)
ing形式貌似没有表示目的的。。。 除非这种目的伴随状语吧
to do sth. 和doing sth.一般是在这些方面转换
总的来说,to do sth.是动词的不定式,doing sth.是动名词形式
很多情况是可以转换的,意思差不多,不过运用到的语法知识有时候稍微有点不同而已
it is adj. to do sth./ doing sth. 不定式/动名词作为真正主语,it是形式主语
to do sth./ doing sth. is adj. 不定式/ 动名词作主语
sb. like to do sth./ doing sth. 不定式/动名词作宾语
很多情况是用法差不多的,但是有些特殊用法,只能使用其中一种,那类型的要自己积累了~~
如只有feel like doing sth. 想做某事
还有那些 regret to do, regret doing sth
remember/ forget to do . remember/forget doing sth. 这种意思完全不一样的
多看看慢慢会有感觉的~~
