Using his hybrid rice farmers are producing harvests twice as large as before. (L23P10) 用他的杂交水稻,农民种出的粮食比以前多了一倍。 1). 句中 Using his hybrid rice 做状语,表原因。又如: Reading English every morning, he improved his English quickly. 2). 英语中的倍数表达法共有三种形式:

He is in the army. 他在军队服役。 She is in computers. 她从事计算机行业。 三.Extensive Reading:(泛读) Reading and Writing: (P14) I.
