B．come over
C．come on
D．come up to
网考网参考答案：A，答错率：52%
网考网试题解析：
[解析] A项come up with的意思是“提出”，符合题意。如：He couldn't come up with an appropriate answer just at the time. (那时他想不出一个合适的答案。)其他三项“B项come over过来；C项come on开始，赶快；D项come up to达到，符合”都不正确。本题空格处是说回答不上来。因此A项为正确答案。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
