Improvement一詞多問
剛剛查看多本字典有關improvement的例句,
1. Extremely crude estimates suggest some improvement over the last two years.
2. We need to carry out some improvements to the system.
3. Our results have shown some improvement this month.
4. I cannot see any improvement in your writing.
而查Yahoo!字典顯示:
改進,改善;增進[U][C][(+in)]
有時係[U],有時係[C], 什麼時候是可數,什麼時候不可數?
有為什麼有的需要加s,有的不需要?
另外,
1. There has been continual improvement in standards.
2. There has been a certain improvement in living conditions.
3. Painting the room yellow is a great improvement.
4. Learning from experience is a recipe for continuous improvement.
為什麼2,3的improvement前需要冠詞a,但是1,4則不需要?
如果我在第3句+了a,
即: Learning from experience is a recipe for a continuous improvement.
和 There has been a continual improvement in standards.
咁係咪即係錯呢?
可能問得有點複雜,請不要介意!Thank you!
