He often gets up at six. But yesterday he________ at seven. 　　2. My father always buys a cake for me every year on my birthday. But last year he ______ a book for me. 　　3. Tom always plays chess with peter. But yesterday peter _______. 听力教学建议 　　教学中，教师应先让学生仔细听清动词过去式发音，并注意跟随教师模仿。再在听力材料中挖去动词的过去式，听完之后，要求学生填充所缺的单词，最后可以让学生跟读课文。 语法教学建议 　　本单元的语法教学应主要围绕一般过去时展开，教师应设计各种情景，给学生提供机会练习。 　　（1）教师可以在黑板上画一张教室图，门前有棵树。编一段对话，借这棵小树之口向小鸟按下表介绍小明过去和现在在校的表现： Time Activities Time Activities Last year Careless Now More careful Last summer Swim This summer Play football Last term Like Chinese This term Like English 　　Tree: I am the tree in the school .I know Xiao Ming well. Every day I see him study in the classroom. Bird: Was Xiao Ming a careless boy? 　　Tree: Yes, He often forgot his glasses last year. He even forgot the telephone number of his family. 　　Bird: Does he often forget anything now? 　　Tree: No, he became more careful now. 　　Bird: Did Xiao Ming like Chinese last term? 　　Tree: Yes, but this term, he likes English better than Chinese. 　　Bird: What sports did Xiao Ming do last summer? 　　Tree: He often swam last summer. 　　Bird: When and where did he swim last summer? 　　Tree: He often swam in the river after school. But this summer he always plays football. 　　（2） 教师可以要求学生将第三十三课第二部分按对话的内容改写成一篇日记以加深学生对对话的掌握如下： 　　I got up at 6:45. I went for a walk and bought a newspaper before breakfast. I read newspaper at breakfast. After breakfast Mr. and Mrs. Turner came to see me. He started packing at 9:15and finish it at 10:40. need“需要”注意的几个方面 　　1) need 名词, 意思是“需要、必要”。其复数形式是“必需品”。例如： 　　There is no need to hurry. 没必要着急。 　　I feel the need of exercise.我觉得需要运动。 　　We are in need of food. 我们需要食物。 　　need用作不可数名词时，还有“贫穷、不幸、逆境、困难”等意思。例如： 　　Many families are in great need.许多家庭处于贫困的情况。 　　A friend in need is a friend indeed. 患难见真情。 　　2) need用作实义动词时，意思是“需要、必须、必要”。例如： 　　My coat needs mending.我的上衣需要缝补。 　　I need some money. 我需要一些钱。 　　We need to work hard. 我们必须努力工作。 　　3) need用作情态动词时，意思是“需要、必须”，常放在疑问句和否定句中。例如： 　　Need he go? = Does he need to go? 他必须去吗？ 　　“Must I do my homework now?”“我现在必须马上做作业吗？” 　　“No, you needn’t.” “不，不必。” 　　注意：need作情态动词时，因为无人称和时态的变化，所以它的过去时用had to来代替，而将来时则用will have to来代替。例如： 　　He had to get up early because he wanted to climb the hills. 　　 他必须早起因为他想去爬山。
