问题 With high hopes, the company sent samples of the substance to scientists, but they couldn’t ______ any practical uses for it.

选项 A、come up with
B、do justice to
C、get even with
D、look up to

答案A

解析 本题空格处是说科学家们对它提不出任何实用之处。A项come up with“赶上,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do justice to“公平对待,适当处理”;get even with“报复”; look up to“尊敬,仰望”都不正确。
