NOTE ON USAGE 用法:In many verbs beginning with re- the prefix is pronounced / rɪ-; rɪ-/ or / re-; rɛ-/ and it may have lost its original meaning of `again' or `back' 在以re-开始的许多动词中,这个前缀读作/ rɪ-; rɪ-/或/ re-; rɛ-/,并有可能已失去原来的‘再﹑ 又’或‘回’等意义:/ rɪ-; rɪ-/ recall,repair; / re-; rɛ-/ represent.Other verbs have had re- added to them with the meaning of `again' and it is pronounced / riː-; ri-/ 另有一些动词加re-表示‘再﹑ 又’之意,读作/ri:-; ri/:reopen; recreate.There are a few verbs which fit into both groups and a hyphenmay be used to show the distinction 还有一些动词适合於上述两种情况,可用连接号表示这种区别:recount`tell a story',re-count `count again'; recover = `get back' or `become well again',re-cover = `supply with a new cover'.
