問一句英文的句子有冇錯~

A good diet and exercise can be the key to protect yourself from getting a cold.

to 之後要用infinitive
所以唔可以係 protecting
要係protect

我覺得冇錯！！！

我覺得o甘講好o的,請參考
Good diets and exercises can be the keys to protect you from getting a cold.

其實你成句野除左protecting之外，文法上冇錯。不過我覺得意思上可以好d。
例如: a good eating habit and/with regular exercise is/are the key(s) to prevent you from getting cold.
diet唔係錯，不過通常會用eating habit。
exercise要係regular先對身體有幫助。
prevent意思上會好過protect。

A good diet and exercise can be the key to protect yourself from getting a cold.

or

A good diet and exercise can be the key for protecting yourself from getting a cold.

正確既應該係:

A good diet and exercise can be the key to [protect] yourself from getting a cold.

因為"to"之後唔應該用"ing".

"ing"之後應該係用現在式.

希望幫到你la.

有
講得不夠全面
應係
A good diet and exercise can be the key to protecting yourself from getting a sick.
