"his assignment verged on the impossible"
"an impossible dream" "an impossible situation"
"impossible behavior" "insufferable insolence"
误 It is more impossible than to work with him.
正 It is impossible to work with him.
析impossible意思为“不可能的”,无比较级和最高级。
今天不会下雨。误 It is impossible to rain today.
正 It is improbable to rain today.
析impossible含义是不可能做到的、不具备可能性的。而improbable含有不大可能发生的意思。“天有不测风云”,本句的意思并非指不能下雨,而是并无要下雨的迹象,因此要把impossible改为improbable.
