四、句型万花筒:同学们,同义句变身挑战开始啦! 请根据上一句话,把下一句话补充完整,快来试试你的“魔法小手”吧!
1. This is my bag. = This bag is .
2. That is your book. = That book is .
3. This is her ruler. = This ruler is .
4. That is his pencil. = That pencil is .
5. These are their pens. = These pens are .

1. mine
2. yours
3. hers
4. his
5. theirs

这道题考查五年级所学的形容词性物主代词和对应名词性物主代词的转换规则：形容词性物主代词后面必须搭配名词使用，而名词性物主代词本身就等价于“形容词性物主代词+名词”，后面不需要再接名词，就可以直接表达所属关系。
1. 原句里的形容词性物主代词my，对应的名词性物主代词是mine，含义为“我的（包）”。
2. 原句里的形容词性物主代词your，对应的名词性物主代词是yours，含义为“你的（书）”。
3. 原句里的形容词性物主代词her，对应的名词性物主代词是hers，含义为“她的（尺子）”。
4. 原句里的形容词性物主代词his，对应的名词性物主代词形式不变，仍为his，含义为“他的（铅笔）”。
5. 原句里的形容词性物主代词their，对应的名词性物主代词是theirs，含义为“他们的（钢笔）”。

五、情境小剧场:Amy 和 Sarah 正在挑选去夏令营的帽子。选择合适的句子补全对话。
Amy:Sarah, let's buy a hat for the summer camp. Look at this yellow one. It has a sunflower on it!
Sarah:1. But it's too small for me.
Amy:Oh, right. What about this orange one? It's big and has a little bird on it.
Sarah:2. It's so pretty!
Amy:Try it on!
Sarah:Wow, 3. It's just right!
Amy:And it's cool. You won't feel hot in it.
Sarah:Perfect! 4.
Amy:Great! Let's pay for it now.
Sarah:5.
A. That's nice!
B. I'll take it!
C. I like !
D. OK!
E. it looks great!

1. A 2. C 3. E 4. B 5. D

我们结合对话的情境逻辑逐一匹配选项：
1. 第一空：Amy向Sarah展示印有向日葵的黄色帽子，Sarah先对帽子给出正面评价，之后转折说明这顶帽子对自己来说太小，A选项“That's nice!（那很不错！）”符合此处语境。
2. 第二空：Amy接着推荐印有小鸟图案的橙色帽子，Sarah表达对这顶帽子的喜爱，紧接着夸赞帽子很漂亮，C选项“I like it!（我喜欢它！）”符合此处语境。
3. 第三空：Sarah试戴帽子之后，发现帽子大小刚好，评价帽子上身后的效果，E选项“it looks great!（它看起来棒极了！）”符合此处语境。
4. 第四空：两人都认为这顶帽子合适又凉快，Sarah决定买下这顶帽子，B选项“I'll take it!（我要买它！）”符合此处语境。
5. 第五空：Amy提议现在去结账付款，Sarah对这个提议作出回应，D选项“OK!（好的！）”符合此处语境。
