×This is very difficult to be done.
✓This is very difficult to do.
在 "It is difficult to..." 或 "This is difficult to..." 的句型中，動詞應使用主動不定詞 (to do)，而非被動不定詞 (to be done)。
×I am difficult to understand this concept.
✓It is difficult for me to understand this concept.
主詞錯誤。"Difficult" 描述的是事物或任務的性質，而非人的狀態。應使用 "It is difficult for someone to..." 的結構。
×He is a difficult person to work.
✓He is a difficult person to work with.
當形容詞 "difficult" 修飾的名詞（如 person, book, place）是後面不定詞動作的對象時，需要加上適當的介系詞（如 with, for, on）。
×I feel difficult when speaking English.
✓I find it difficult to speak English. / Speaking English is difficult for me.
中文常說「我感到困難」，但英文的 "feel difficult" 並不正確。應使用 "find it difficult to..." 或 "...is difficult for me" 來表達。
×The test was more difficult than I thought.
✓The test was more difficult than I had thought.
在比較句中，若主句是過去式（was），而「想」的動作發生在更早之前，從句應使用過去完成式（had thought）以表達時間的先後順序。
×This job is too much difficult.
✓This job is too difficult. / This job is much too difficult.
"Too" 修飾形容詞時，前面不需要再加 "much"。若要加強語氣，應使用 "much too + 形容詞"（much 修飾 too）。
