四、情境小剧场。
任务一:Lingling 和妈妈正在为暑假旅行买背包。选择合适的句子补全对话。
Mum:Lingling, let's buy a new bag for our summer trip.
Lingling:Great! Look at this black one. It's nice!
Mum:1.
Lingling:Oh, right. What about this green one?
Mum:2. But it's too small. We need a big one.
Lingling:Look at this blue one! It's big and light. And it has four wheels!
Mum:3. It'll be easy for you to pull.
Lingling:And it has two pockets! I can put my umbrella and toy in them.
Mum:Perfect! 4.
Lingling:Hooray!
A. It's light.
B. But it's very heavy.
C. Let's take this one!
D. Wow, it's great!

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

我们可以根据对话的上下文逻辑逐一匹配选项：
1. 第一空：Lingling夸赞黑色的包好看后，Lingling后续认同妈妈的话并换选了绿色的包，说明妈妈指出了黑包的缺点，选项B“但是它很重”符合语境。
2. 第二空：妈妈后半句转折说绿色的包太小，前半句是对绿包的正向评价，选项A“它很轻”符合先讲优点再转折说不足的逻辑。
3. 第三空：Lingling介绍蓝色的包又大又轻还带轮子，妈妈后续说这个包拉起来很方便，此处妈妈先对这个包发出夸赞，选项D“哇，它太棒了！”符合语境。
4. 第四空：妈妈说这个包很完美，之后Lingling开心欢呼，说明妈妈决定买下这个包，选项C“我们就买这个吧！”符合逻辑。

任务二:创编对话。放假,与家人去商场挑选去海边游玩的旅行箱,以(看中颜值款→发现不实用→选中实用款)为故事蓝本,和朋友合编英语对话,可加入创意拓展。
创编要求:
1.参考句型:It's+形容词+for sb./It'll be easy to do / But it's...;
2.创意拓展:可添加旅行箱颜色、卡通图案、沙滩收纳细节等;
3.实践体验:可做简易旅行箱道具,完成后录制小视频或现场展示。
参考剧本:
You:Dad, look at that blue suitcase! It has a dolphin pattern(图案)! It's so nice!
Dad:It's lovely, but (发现问题,如 it's too heavy for you to pull 等).
Salesman:Hello! Try this blue one too. It's and (如 big, light 等).
You:Great! It has and (如 four big wheels, a side pocket 等).
Dad:It'll be easy for you to (如 pull it on the beach 等).
You:Perfect! We'll take it! We can put my sand toy in it!
Salesman:Have a great summer trip!

第一空：it's too heavy for you to pull, and it is too small to hold all your beach things
第二空：light
第三空：big
第四空：four big wheels
第五空：a side pocket for your sunglasses
第六空：pull it on the beach sand

本题是小学英语情景创编填空题，要求贴合"看中高颜值旅行箱→发现其不实用→挑选适配海边出游的实用款旅行箱"的故事逻辑，使用题目给出的参考句型，选用符合五年级英语水平的基础词汇完成对话填写，内容匹配海边出行的场景设定即可。
