解答
(1)没有be up to do这种说法.
(2)be up to doing sth. (体力或智力上)能胜任:I'm not up to going to work today.今天我不能去上班.(可能是身体不舒服.)
(3)be up to sth. (体力或智力上)能胜任:He is not up to the job.他无法胜任这项工作.
(4)be up to sb 是……的职责(或责任),由……决定.
(5)It is up to you是上面这个短语的具体化,意思是“是你的职责(或责任)”,“由你决定”.
(6)It is up to sb to do sth.是be up to sb的扩展,意思是“做某事是……的职责(或责任)”,“要不要做某事由某人决定”.
