Unit 1 The Snail and the Rose Tree.

  we must clean our classroom every day.   must 也表示“義務”，這種義務來自講話人，表示講話人的要求，當我們表示這種要求不是來自講話者，而是來自別人或其他外界因素。（如各種規章制度）時，常常用have to。例如：  you have to do your exercises in class.   i really must stop smoking. 2. raise  v. 舉起   例如：  if you have any questions, you can raise your hands first.   please raise your voice, i can’t hear you.   同義詞lift   辨析：raise，rise 和lift   raise 是及物動詞，后面可接賓語，多指將物體垂直向高處或將其從較低的平面移至較高的平面。  rise  是不及物動詞，不可以加賓語，主語一般是日、月、云、霧、煙、溫度、河水、物價等。  lift 表示“從平面上提示，使直立”等，可以和raise替換，而lift 強調舉起某些沉重物體需要費一些力氣。3. in a little while you’ll be nothing but a stick.   ①nothing but  僅僅，只，例如：  there is nothing but a story book in his bag.   the child dreams of nothing but going to the zoo.   he did nothing but grumble.   the baby can do nothing but crying.   my brother ate nothing but a bowl of porridge. ②in a little while   過一會兒，通常用于將來時you’ll be warmer in a little while. 4. you may come to an end soon.   come to an end  結束  come to a stop 停下來  come to an understanding 商定、約定、諒解  come to hand  到手  come to life  蘇醒，活過來  come to light  真相大白  come to little  無甚結果  come to nothing 成為泡影  come to no good (end)  沒有好結果  come to the same thing  結果相同，都一樣5. “no”, replied the rose tree.   reply  回答   短語為：  reply to sb. 回答某人，答復某人   例如：  he replied to me: “mr. wang has gone to shanghai.” 6. strength   n. 力，力量，力氣，實力    例如：  the strength of body  體力  have great strength of character 有堅強的性格  pull with all one’s strength 用全力拉  詞的派生：  strengthless adj. 無力量的  strengthen   v. 加強，鞏固，使堅強7. i have to bloom over and over.   over and over  一再地，再三地  同義詞：again and again   相同結構：on and on 繼續不斷地，不停地  laugh and laugh 笑啊笑8. we have to offer our power and give others the best of ourselves.   offer our power  提供我們的能量  offer vt.  主動給予，提供，拿出  offer sb. sth. 為某人提供某物
