Because of the annual deaths from avalanches on ski slopes, <alternative ways to protect> the skiers ought to be explored.

A) alternative ways to protect

B) alternative ways of protection of

C) alternatives to protecting

D) alternatives of protection of

E) alternative protections for

 答案a

我选c，为什么不对，我觉得更简洁，alternative有没有固定用法？请大牛们指教。

(C). alternatives to DO, not protecting

A. vs. E.

Now you need to understand the Precision of language.

you know death due to avalanches, what do u need to do?

Find new Ways to protect skiers. (A)

"Alternatives" is too broad and general, could mean: better ski suits, safer ski slopes, equip skiers with survival kits, more ski patrol, blah blah blah

E. alternative protections: better ski gear. That won't stop avalanches.

alternative to doing or alternative to do???

for instance

I wanted to go out, but I had no money. I had no alternative to staying at home.

the above sentence is from a dictionary.

so maybe alternative & "alternative way" can not be used in the same way.

confused laaaaaaaaaaaaaaaaa

alternative ways to protect 指的是way，后面加的不定式

alternative 有名词形式，表示可供选择的办法，感觉应该是加of，或者是to do

你的这句句子和longman上的句子有冲突

一下是longman的解释，做名词

something you can choose to do or use instead of something else
alternative to
Is there a viable alternative to the present system?

If payment is not received within five days, legal action will be our only alternative .

I had no alternative but to report him to the police.
    

He quickly assessed what alternatives were open to him.

似乎你句子也该改成：

I wanted to go out, but I had no money. I had no alternative but to stay at home.

thanks,固定用法

an alternative to sth

no alternative but to do sth
