What用途广,要问“什么”它当先。(What’s this?)How开头来“问安”。(How are you?)Who问“谁”。(Who’s that man?)“谁的”Whose来承担。(Whose eraser is this?)询问“某地”用Where。(Where is her cat?)“哪一个”Which句首站。(Which one?)-es后边紧跟随,study→studies看明白。be going to, 表打算,准备、计划将干。下列词,要注意,come go和离去(leave)have和has用had,do和does变did。(一)有can有be,can、be后面not添 (二)没有can、be、do、does显身手,单三用doesn’t,doesn’t后面动还原
