高中英语单词拼写中的词性,词形,词义的教学设计

教学设计
单词拼写中的词性，词形，词意
一、学情分析
本节内容是在学生上了高中以后新增加的考试题型之一，同时也是学生头疼的题目之一。

1.已具备的知识及能力：学生记单词只记汉语意思及单词的正确拼写。

2.欠缺的能力：结合语境确定恰当的词性、词形
二、教学目标
1.知识与技能
（1）了解汉英之间的准确意义转化。

（2）会根据语境进行词性、词形的判断。

2.过程与方法
（1）学会全面观察、分析语境，提高学生观察思维和自学能力。

（2）通过探究语境培养学生的动手、动脑和运用知识的能力、观察能力。

3.情感态度价值观
通过掌握词意、词性、词形，使学生进一步意识到语境的重要性，帮助学生树立起全局的观念。

三、教学重点难点
1. 单词拼写中的词性，词形，词意的判断
2. 如何进行单词拼写中的词性，词形，词意的判断
五、教具准备
电子白板、投影仪、练习试题
六、教学过程
Step 1. Greetings the whole class.
Step 2. 投影展示
五个没有词形变化的例子（设计意图：给学生信心，只要写对单词就可得分）。

1. Jack is rich, but he is very (吝啬). He never lends money to others.
2. He said he would (投入) all his life to the research.
3. Hearing the joke, the students (迸发) into laughter.
4. The little girl is afraid of thunder and (闪电).
5. Here is some (建议).
Step 3. 投影展示
六个需要词形变化的例子（设计意图：要根据语境才能进行词性、词形变化的判断）。

Have a try:
1. Here are some (建议).
2. The prisoner ran away by (挖) an underground tunnel.
3. Lisa laughed and (聊天) happily with the other women.
4. Parents noticed the (逐渐) change in their children.
5. The boss left a 10% (小费) after dinner.
6. This kind of machine was invented in the ________ (十九) century.
Step 4. summary
总结：做题时，各种词性的单词需考虑的问题
▪ noun: U; C (sl/pl)
▪ verb: 谓语 （时态及语态形式）
▪ 非谓语 （v-ing; v-ed; to do 形式）
▪ adj / adv
▪ Num (基数词;序数词)
解题思路：
▪ 1、根据语境确定所填单词的确切含义和词性；
▪ 2、根据所填单词对应词性的考点确定单词的正确形式，进行填写。

Step 5 Have a try （注意词性）
设计意图：句子中所给的汉语提示，并不能完全体现单词的词性，要根据语境判断。

只要努力，就会成功。

1. be .

3. .
