這個問題我會，雖然本人英語口語不是很好，但是對英語四六級詞匯還是很熟悉的~下面給大家從三個方面具體解釋壹下：
含義
come up意思是：出現，被提出。
come up with意思是：隨．．．出現，提出。
壹般來說come up（表示被提出）它的主語是事或物。come up with的主語是人。
用法
come up走近，被提及，即將到來，突然發生，升起異同之處：come up壹般不直接跟賓語，跟賓語時常用與介詞with連用。例1：They tend to enjoy the moment when something good is happening, and seize opportunities that?come up. (2015年12月四級)他們傾向於享受好事發生的時刻，抓住到來的機會。結構分析：They是主語，tend to enjoy是謂語，the moment是賓語when引導狀語從句，something good是主語is happening是謂語,and是連接兩個並列成分的連詞，seize是謂語，opportunities是賓語，that?come up是定語從句。
come up 出現,被提出come up with 隨...出現,提出.壹般來說,come up （表示被提出）它的主語是事,或物.come up with 的主語是人.比較：The plan came up at the meeting.He came up with the plan at the meeting.
