2、，意為“一邊一邊”when強調動作的先后性，從句動詞可以是延續(xù)性動詞也可以是非延續(xù)性動詞。while強調動作的持續(xù)性及同時性，從句常用延續(xù)性動詞。1.連接詞when, while, as 的用法區(qū)別用while, when填空： Mozart started writing music _ he was four years old.

12、強的學科，前面的知識沒學懂，后面的學習就很難繼續(xù)進行。因此，掌握基本概念是學習的關鍵。上課時要抓好概念的理解，同時，大家要開動腦筋，思考老師是怎樣提出問題、分析問題、解決問題的，要邊聽邊想。為講明一個定理，推出一個公式，老師講解順序是怎樣的，為什么這么安排？兩個例題之間又有什么相同點和不同之處？特別要從中學習理科思維的方法，如觀察、比較、分析、綜合、歸納、演繹等。 作為實驗科學的物理、化學和生物，就要特別重視實驗和觀察，并在獲得感性知識的基礎上，進一步通過思考來掌握科學的概念和規(guī)律，等等。 二、聽文科課要注重在理解中記憶 文科多以記憶為主，比如政治，要注意哪些是觀點，哪些是事例，哪些是用觀點解釋社會現(xiàn)象。聽歷史課時，首先要弄清楚本節(jié)教材的主要觀點，然后，弄清教材為了說明這一觀點引用了哪些史實，這些史料涉及的時間、地點、人物、事件。最后，也是關鍵的一環(huán)，看你是否真正弄懂觀點與史料間的關系。最好
