Setting goals is the first step in
achieving them.这是高中英语新教材译林版必修1第1单元的两个句子(p7)。不是说 the first…后面要接不定式作定语吗?为什么这里用 in achieving them?能不能改为 to achieve them 啊?
答案写的是china's effort and target for green energy use,我写的是china's efforts and target of using green energy,还有一种方式就是china's efforts and target in using green energy这三种表达方式都对吗?
