二、乐乐给妈妈唱了一首儿歌。请选择合适的选项补全歌词。

我们结合句子含义和常用固定搭配逐一匹配选项：
1. 第一句“Mum cooks ___ in the kitchen.” 表达妈妈在厨房做午饭，选B选项lunch（午餐）符合语境。
2. 第二句“Lunch is ready, little ___.” 表达午饭准备好了，小宝贝，选A选项child（孩子）符合语境。
3. 第三句“Sit on your ___ and have a bun.” 表达坐在你的椅子上吃小面包，选E选项chair（椅子）符合语境。
4. 第四句“The bun looks like a ___.” 表达这个小圆面包看起来像一个桃子，选C选项peach（桃子）符合语境。
5. 第五句“I like it so ___.” 是固定表达so much，意为“非常”，选D选项much符合搭配和语义。

三、乐乐正在向现场的亲友们介绍他的妈妈。阅读短文，找出含有与所给单词画线字母组合发音相同的字母组合的单词，写在四线三格里。
Hello, everyone! Welcome to our home! Today is my mother's birthday. This is my mother. I love her so much. She is very helpful at home. She often cooks in the kitchen. She can make good lunches. She is also helpful at school. She is a teacher. She teaches Chinese. She is nice to her students.
peach

much、kitchen、lunches、teacher、teaches、Chinese

首先确定所给单词peach中画线字母组合ch的发音为/tʃ/，接着在短文中逐一查找含有字母组合ch、且ch发音为/tʃ/的单词即可。
