初三英语造句
1.我哥哥参军两年了.2.这本字典我借了十天了.两句都用for+一段时间;since+时间点;since+一段时间+ago;since+从句(时间状语从句)这四种方法各造四句句子.
1. (1) My brother has been in the army for two years. (2) My brother has been in the army since 2008. (3) My brother has been in the army since two years ago. (4) It's two years since my brother jioned the army. --- jion 是终止性动词,不能与延续时间连用.即不能用于 (1),(2),(3)句中. 2. (1) I have kept this dictionary for ten days. (2) I have kept this dictionary since September 1st. (3) I have kept this dictionary since ten days ago. (4) It's ten days since I borrowed this dictionary. --- borrow 也是终止性动词,与延续性时间连用时,要转换成 keep
