高教版中職英語（基礎(chǔ)模塊第2冊）Unit7《Somuchtodobeforewetravel》課件

時間狀語從句掌握狀語從句的關(guān)鍵準(zhǔn)確掌握每一個連詞的含義。注意主句和從句的時態(tài)呼應(yīng)。狀語從句分類表示時間表示地點(diǎn)表示原因表示結(jié)果表示目的表示條件表示讓步表示比較時間狀語從句？

用表示時間的連詞連接一個句子作狀語，這樣的主從復(fù)合句就是時間狀語從句。

連接詞：when,while,as,before,after,until,not…until,since,the

moment,each

(every,next,the

first)time

…連接詞類別作用asas

從句中動詞是延續(xù)性時，側(cè)重表示主從句動作同時發(fā)生，意為“一邊…一邊…”when強(qiáng)調(diào)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(qiáng)調(diào)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

Until編后語同學(xué)們在聽課的過程中，還要善于抓住各種課程的特點(diǎn)，運(yùn)用相應(yīng)的方法去聽，這樣才能達(dá)到最佳的學(xué)習(xí)效果。一、聽理科課重在理解基本概念和規(guī)律

數(shù)、理、化是邏輯性很強(qiáng)的學(xué)科，前面的知識沒學(xué)懂，后面的學(xué)習(xí)就很難繼續(xù)進(jìn)行。因此，掌握基本概念是學(xué)習(xí)的關(guān)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??問題、分析問題、解決問題的，要邊聽邊想。為講明一個定理，推??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(diǎn)和不同之處？特別要從中學(xué)習(xí)理科思維的方法，如觀察、比較、分析、綜合、歸納、演繹等。作為實(shí)驗(yàn)科學(xué)的物理、化學(xué)和生物，就要特別重視實(shí)驗(yàn)和觀察，并在獲得感性知識的基礎(chǔ)上，進(jìn)一步通過思考來掌握科學(xué)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(diǎn)，哪些是事例，哪些是用觀點(diǎn)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(diǎn)，然后，弄清教材為了說明這一觀點(diǎn)引用了哪些史實(shí)，這些史料涉及的時間、地點(diǎn)、人物
