介詞with用法詳解是一個十分有用的介詞，其用法也比較複雜，以下用法值得注意：1. 表示方式、手段或工具等時（=以，用），注意不要受漢語意思的影響而用錯搭配，如「用英語」習慣上用in English，而不是with English。
2. 與某些抽像名詞連用時，其作用相當於一個副詞。
如：with care=carefully 認真地with kindness=kindly 親切地with joy=joyfully 高興地with anger=angrily 生氣地with sorrow=sorrowfully 悲傷地with ease=easily 容易地with delight=delightedly 高興地with great fluency =very fluently 很流利地3. 表示條件時，根據情況可與虛擬語氣連用。
如：With more money I would be able to buy it. 要是錢多一點，我就買得起了。
With better equipment, we could have finished the job even sooner. 要是設備好些，我們完成這項工作還要快些。
4. 比較with和as：兩者均可表示「隨著」，但前者是介詞，後接名詞或代詞；後者是連詞，用於引導一個句子。
比較：He will improve as he grows older. 隨著年齡的增長，他會進步的。
People’s ideas change with the change of the times. 時代變了，人們的觀念也會變化。
