at the very last moment
在最后时刻 (zai zuihou shike)
"He submitted his assignment at the eleventh hour."
"他在最后时刻提交了他的作业。" (Ta zai zuihou shike tijiao le tade zuoye.)
to just barely manage to do something
working late into the night
a small part of a much bigger problem
to review a situation carefully before making decisions
to think creatively or unconventionally
to identify or recognize something with precision
