Grammar FocusGrammar learning读一读，感知句子用法Grammar learning现在完成时的结构主动语态：has/ have +过去分词被动语态：has/ have been +过去分词被动语态是由主动语态变来的！ Grammar learning现在完成时--- since 和 for 的用法1.现在完成时表示动作或状态从过去某一时刻开始、一直持续到现在，多与“since +点时间”或“for +段时间”连用。for表示“经过(一段时间)”，而since表示“自从(……以来)”。 常见结构如下：for +表示一段时间的状语 一段时间+ agosince + 表示过去的某一时间点 从句2.在对现在完成时的时间状语进行提问时，我们常用how long— How long has Mary been a teacher?— Since two years ago./For two years.He has lived here since 1991. 他从1991年起就住在这里了。He has lived here since he was born. 他从出生起就住在这里。Grammar learning3.英语中有些动词的意义不能延续，表示的是一瞬间就结束的动作，这些动词被称为非延续性动词或短暂性动词，常见的如 come, leave, go, lose, see, begin, start, arrive, become, die, buy, borrow, close, join, reach, fall, get up 等。这类动词可以用于完成时态，但在肯定句中不能与表示动作延续的时间状语 for 或 since 短语连用。正：He has come back. 他已回来。 误：He has come back for three days. 正：He has been back for three days. Grammar learning4.在表示持续一段时间的句子中，应将短暂性动词转化为相同意义的延续性动词或状态动词。Grammar learningGrammar learningRewrite the sentences using for or since.1. Jim is in Japan. He arrived there three days ago.2.
