why?名詞性從句、狀語從句以及定語從句這三大從句是高中最重要的語法點。對于從句的考察貫穿高考英語試卷的始終，從第一個單項聽力，到最后的寫作。三者重要性不分伯仲。但正如大家知道的，“三大〞之一的狀語從句，種類繁多。時間、地點、原因、結(jié)果、條件、讓步、目的、比較、方式9種。這9種之中，對于高考來說，重要性的區(qū)別是很大的。考頻為證，以2006-2021年5年全國高考18個省市的19套卷子的單項選擇題為例，涉及到狀語從句的題目共有93道，其中時間狀語從句考到了24題。由此可見,時間狀語從句為重中之重。LearningAims(學(xué)習(xí)目標(biāo))2整理ppt1.掌握并靈活應(yīng)用when,while,as的根本用法及區(qū)別；2.學(xué)習(xí)并掌握when,while的特殊用法；3.掌握since,before主從句的時態(tài);4.區(qū)分since,before常用句型。Knowledgeandskills
