應(yīng)該是 began to throw 吧.
begin to throw是“開(kāi)始扔”的意思,例如"Roger gathered a handful of stones and began to throw them." 意為：Roger收集了一把石子,開(kāi)始向他們?nèi)尤?
另外,begin to throw up+sth表示開(kāi)始出現(xiàn)……問(wèn)題/情況.例如The changes in the computer world began to throw up problems.電腦世界的變化開(kāi)始產(chǎn)生問(wèn)題.
如果begin to throw up后面不加賓語(yǔ)的話(huà),表示“開(kāi)始嘔吐”,因?yàn)閠hrow up這個(gè)短語(yǔ)有“嘔吐”的意思.
