if的主将从现用法
if的“主将从现”原则是if引导条件状语从句时，主句一般将来时，从句一般现在时(即:一般现在时表将来，在第七单元一般将来时态的五种用法中已经提及)。例句：Ifyougototheparty,youwillhaveagreattime!(从句:参加派对还未发生，描述将来)。if包含两种含义，“如果”与“是否”，表示如果时，并引导条件状语从句时，才遵循“主将从现”原则，当表示是否，引导宾语从句，不遵循此原则，从句的时态需要根据实际语境选择。绛旓細if鐨勨滀富灏嗕粠鐜扳濆師鍒欐槸if寮曞鏉′欢鐘惰浠庡彞鏃讹紝涓诲彞涓鑸皢鏉ユ椂锛屼粠鍙ヤ竴鑸幇鍦ㄦ椂(鍗:涓鑸幇鍦ㄦ椂琛ㄥ皢鏉锛屽湪绗竷鍗曞厓涓鑸皢鏉ユ椂鎬佺殑浜旂鐢ㄦ硶涓凡缁忔彁鍙)銆備緥鍙ワ細Ifyougototheparty,youwillhaveagreattime!(浠庡彞:鍙傚姞娲惧杩樻湭鍙戠敓锛屾弿杩板皢鏉)銆俰f鍖呭惈涓ょ鍚箟锛屸滃鏋溾濅笌鈥滄槸鍚︹濓紝琛ㄧず濡傛灉鏃讹紝骞跺紩瀵兼潯浠剁姸...
