Question

问一段字典上的英文,看不懂了,
firmly; completely:Within a few minutes she was fast asleep (= sleeping deeply).The boat was stuck fast (= unable to move) in the mud.
There is no noun related to fast.Use speed in connection with vehicles,actions,etc.; quickness is used about thinking.
--------------------------------
把上面的翻译下,最好解释下,有些糊涂.
fast没有名词形式。一般在形容车辆或者动作时用speed等，而quickness用来指思维敏捷。
........这段能否帮我造个句子呢，我还是有点没会用这里面的说法。fast speed quickness，帮我造下句子，我能清晰些

Answer 1

这段话是解释fast的
它有一个意思是“彻底,完全”,比如：几分钟以后,她就睡着了（等于“睡熟了”）.船完全陷（不能动）在泥里了.
fast没有名词形式.一般指车辆或者动作速度快用speed等,而quickness用来指思维敏捷.
