答案：1. 演绎法
英语中，有些及物动词后接宾语时，还需要加一个词或短语来补充说明宾语的情况，这样的词或短语叫做宾语补足语。那么请大家从课文中找出几处关于宾语补足语的例句。
e.g.Now when people refer to England you find Wales included aS well. So to their surprise the three countries found themselves united. 同学们可以看出，例句中included是作find的宾语补足语，united是作found的宾语补足语。
形容词作宾语补足语时，通常是放在make，get，find，keep，let等动词的后面。
接下来教师通过“辨识一拓展一理解”的步骤依次具体讲解宾语补足语的其他用法。
2. 归纳法：学生首先接触的是包含语法规则的真实上下文，然后根据上下文信息归纳出语法规则。
3. 启发式教学：教师给学生一些特定材料进行阅读或者听说，之后由学生自己找出语法规则。这与归纳法相似，但是不同之处在于启发式教学中教师的角色只是协助和指导。
4. 任务型教学：训练学生应用语法项目时，任务性活动可以包含信息差、调查、讨论、采访、海报制作等。
5. 情景式教学：教师使用真实的情境或者创设模拟情境让学生使用或者练习语法。这些模拟情境包括对材料的使用，肢体语言、多媒体等。 6. 语法练习方法：
(1)机械式练习：机械式练习活动的目的是为了准确，学生不停重复一个关键的句型或者语法结构，替换练习和变型练习是最常用。 (2) 有意义的练习：该练习方式是指对语法的理解、意义的转换和产出，通常在机械式练习之后。
7. 使用提示进行练习：这些提示可以是图片、信息表、模拟表演、表格、创设的情境或者关键词。
(1)词汇呈现方法 ①实物呈现。用实物教单词，借助直观教学手段能动员学生运用各种感觉器官来感知和认识客观现象，让学生把单词和实物联系起来，从而较容易地掌握生词。
②图片呈现。对于一些不能用实物进行教学的单词，图片是很好的教学辅助手段。课文插图、教师自制的挂图、剪贴画、简笔画等都可以用来再现物体，创设情境。
③定义呈现。用直接下定义的方式解释单词的意义，然后教授单词。
④动作表情呈现。对于一些如run，walk之类的单词，可以借助一些形象的动作或生动的表情呈现。
⑤描述呈现。结合词汇表示的事物的特点来呈现单词。
(2) Teaching Aims
Knowledge aim : Students can learn some new words, such as: cloud, sun, rain, vapor and stream.
Ability aim: Students can use the new sentence "Where does the rain come from?" to discuss the formation of rain. Their listening and speaking ability will have an improvement through discussion in groups and pair work.
Emotional aim: Students can have a desire to know more about nature and develop their awareness of environmental protection.
(3)导入和呈现环节
Warming up＆lead—in(导入环节)：
①Daily greeting．
②Show a video about the procedures of raining，and ask students if they have any idea about the formation of rain．
【设计意图】
利用多媒体展示下雨的过程，营造轻松愉悦的课堂氛围。通过设疑，激发学生对雨水的形成展开积极思考，从而引出新课。
Presentation(呈现环节)：
① Teaching "rain"
