想問Adjective何時+ing何時+ed,跟如何分辨?

有些動詞的分詞(participles)經常用作形容詞。

以現在分詞(present participle)形式出現的，用來形容某些人、事或物給人的感覺，通常以 active form 出現。

Word Form: Verbs ending in " - ing "

For example:

Soccer is an INTERESTING sport.
It is a FRIGHTENING dog.
This is a BORING show.

以過去分詞(past participle)形式出現的，只可以用來形容人對某些人、事或物的感受或反應。通常以 passive form 出現，而且有時候接上preposition。

Word Form: Verbs ending in " - ed "

For example:

We are INTERESTED in playing soccer.
Children are FRIGHTENED by the dog.
They are BORED by the show.

相信你指的該是interesting/interested或boring/bored的一系形容詞吧。以-ing結尾的一組是用來指「令自己/他人感到」的人或事，而以-ed一組的則是指「自己/他人感到」。

The book is interesting.
I am interested in reading the book.

John is boring.
I am bored by John.
