prevent from問題?

更新: prevent us from getting disease
prevent us from dust
點解 disease 前面要有getting ,而dust 就可以就咁就得？

小弟個人認為這是語感的差異，如果改成prevent from getting dust，文法上也是正確的，差別在於:
prevent from getting disease表示要避免的是生病的"動作"，即getting (disease)；而prevent from dust要避免的不是動作，其強調的是dust。


更新 2: 爲什麽dust 前面不用Xing?
prevent from為一個"verb+prep."的phrase，當prep.後面要接verb的時候，必須以V-ing的形式接續，將verb轉為noun(V-ing)。因此，本身就是noun的dust當然就不需要加上ing來轉為noun。

以上。

Prevent us from getting disease
=participail--getting;
Prevent us from dusting
=(gerund)
=cleaning away the fine dry earth on floor
Or dust lay thick on the road
or a cloud of dust on the car
-by raise or kick up a dust on that car
from the dusting job.


Prevent us from (getting) dust
=prevent us from dust
=Let our human body clean by preventing from dust !

from為介系詞,介係詞後面要接名詞或動名詞(V-ing)
get為動詞,因此要加ing變成動名詞
dust是名詞,from後面原本就可接名詞,因此不用做任何改變

Example: Who can prevent us from getting married now that you are of age ?==既然你己成年,誰能阻止我們結婚呢? Yip
