It’s a long time since he studied English 主句是完成时吗,怎么没有have
是现在时
再问: since句型主句不是要用完成时
再答: 1) since +过去一个时间点 (如具体的年、月、日期、钟点、1980, last month, half past six)。 I have been here since 1989. 2) since +一段时间+ ago I have been here since five months ago. 3) since +从句 Great changes have taken place since you left. Considerable time has elapsed since we have been here. 4) It is +一段时间+ since从句 It is two years since I became a postgraduate student. 你的应该是第四种情况
