elaborate 後面用咩介詞？
✗ 你會咁寫
The importance of sports can be elaborated to three ways.
✓ 應該係
The importance of sports can be elaborated on in three ways.
elaborate 應該配搭「on」；講「分三方面」用「in three ways」。

點解你會咁寫
介詞係最冇邏輯嘅部分，靠嘅係見得多。所以錯過嗰個搭配要記返落錯題簿，下次見到同一個字先會停一停。

✗ This depends to the situation.
✓ This depends on the situation.
✗ She is good in mathematics.
