求助一道英语问题: come up with ,think of ,think up 有什么区别是否可互换？

thought of 多表示考虑, 想起,关心.英文解释最能说明为什么选B 而不是A了,to have formed a possible but not firmly settled plan for
例子:I'd thought of blue for this room. (blue 是"蓝图")

came up with ,想出,提出,英文解释是to think of (a plan,reply etc.),produce

thought up 想出,设计出.英文解释是to invent--力图想出

整句的关键是有个finally,所以要选择的词组就不仅要和idea 搭配,还要和整句的意思一致.

当然选B了，固定搭配

答案:B.(提出,提供)

A.考虑,关心/ 想起/ 想像
C.无此结构
D. 想出,设计出(用于口语)

B. came up with 是常用语句。是出了一个主意
A. thought 是想出一个主意

B

B
