    為了保證本文的科學務實,文中多處通過對比分析,定性分析等研究方法,具體剖析二者不銜接方面之所在,最終得出結論:由於中考試題的簡單,以教材為中心,不注重分析問題,解決問題等能力的考察,只圍繞課本中原封未動的知識來換題型,進而導致初中英語教學過于強調知識的準確性,而忽略了只有通過廣泛閱讀大量語言材料,不斷輸入新的語言信息才能生成的閱讀能力以及其他語言運用能力的培養,造成初中為高中在能力方面鋪墊過少,高一學生沒有具備進入高中學習所必備的相關能力等不銜接問題;而高考測試注重閱讀能力等綜合語言能力考察的導向確保了高中英語教學從階段就以培養閱讀能力、搜集、整理、分析、綜合各種語言信息的能力為中心等綜合語言能力為中心,由此推出初高中英語教學的不銜接問題從初中既已形成,而在高中教學中表現得尤為出。
