三、将下列单词按“th”的发音分类。

1. /θ/:
2. /ð/:

1. /θ/: thanks think three thin thirteen
2. /ð/: this there them they these that those

【分析】首先明确英语中字母组合th有两种常见发音：清辅音/θ/（发音时声带不振动）和浊辅音/ð/（发音时声带振动）。解题时需逐个判断每个单词中th的发音，再将单词归类到对应音标的类别中。
【解析】逐个分析单词的th发音：
thanks、think、three、thin、thirteen中，th发清辅音/θ/，归为/θ/类；
this、there、them、they、these、that、those中，th发浊辅音/ð/，归为/ð/类。
【答案】1. /θ/: thanks think three thin thirteen；2. /ð/: this there them they these that those
【知识点】英语音标（th发音）、单词发音分类
【点评】本题考查th的两种核心发音的区分，属于基础语音知识题，需学生掌握清、浊th的发音差异并准确判断。
【难度系数】0.5

四、根据汉语及图片提示补全下列句子。
1. The boy is （渴的）and hungry.
2. —What's the （天气）like today? —It's sunny.
3. （这些）pencils are my sister's.
4. Look at the doctor. He's tall and （瘦的）.

1. thirsty 2. weather 3. These
4. thin

【分析】这是根据汉语提示补全英文单词的题目，需结合句子语境、固定搭配及单词的形式要求填写正确词汇，注意指示代词的大小写等细节。
【解析】1. 汉语“渴的”对应英文形容词thirsty，在句中作表语，符合语境；2. 询问天气的固定句型为“What's the weather like?”，故填weather；3. 修饰复数名词pencils的指示代词“这些”是These，位于句首首字母需大写；4. 汉语“瘦的”对应英文形容词thin，在句中作表语描述人物特征。
【答案】1. thirsty 2. weather 3. These 4. thin
【知识点】单词拼写、词汇运用
【点评】本题考查基础英语核心词汇的运用，均为常见常用词汇，难度较低，侧重巩固基础词汇的掌握。
