有这么说的：He didn't buy the book(他当时没有买那本书.)；he wasn't buying the book.(他当时不想买那本书).又如：
1.Philip tried to get me interest in a scheme for producing a new synthetic fibre ,but I wasn't buying it.菲利普力图使我对生产新合成纤维的计划产生兴趣,但是我未上他的当.
2.When the Golden State Warriors began casting their spell on the Mavs Howard was the
only one who wasn't buying.当勇士队把魔咒撒向牛群的时候,霍华德是唯一一个不吃这套的
小牛.
如能帮上你,
