1.Methodical yet brilliantly spontaneous in her approach to dance,Gelsey kirkland was once the premier ballerina of American ballets.

請問一下各位,Methodical 和 brilliantly 不用對稱嗎??..可是為何答案是ballets(可是ballet不是可以加s變複數嗎?)

2.Saltpeter,better known as potassium nitrate,is extremely versatile,found uses in medicine,

agriculture,and chemistry.

請問一下各位,為何這題答案是把found改成finding阿???

I think:1 methodical~ spontaneous,and brilliantly~spontaneous:adv+adj

ballets~ballet i dont know.

2s is extremely versatile.+(finding uses........)it just describe the versatile.

if it is found,V+N become a bad "sentense"

hope others (NN)can give you a better explanation.shrimp can only do like this.
