四選一
Without proper storage, the quality of the printed samples may ____ over time.
看答案
deteriorate
情態助動詞 may 後接原形動詞，因此選 deteriorate。deterioration 是名詞；deteriorating 是 -ing 形式；deteriorated 是過去式或過去分詞，皆不能直接放在此處的 may 後面。
同義改寫
The quality of the fabric samples began to deteriorate after several months in direct sunlight. → The quality of the fabric samples began to decline after several months in direct sunlight.
主詞為品質時，deteriorate 與 decline 都表示品質變差，開始變差的時間條件也相同。
The technician noticed that the rubber seals had deteriorated since the last inspection. → The technician noticed that the rubber seals had become worse in condition since the last inspection.
had become worse in condition 明確表達密封圈狀況變差，保留原句的過去完成式與比較時間點。
