【分析】
这道题是补全对话类题目，解题关键是结合上下文的逻辑关系，找到每个空缺处前后句子的关联点：
1. 第16空：后文提到“要花很长时间找需要的东西”，说明前文是在讲购物耗时，需选对应表达购物费时间的选项。
2. 第17空：前文说买完商品要带回家，承接这个动作，后文应描述购物后的状态，比如疲惫，找到匹配选项。
3. 第18空：前文讲传统购物的不便，后文转而讲可以在家随时购物，这是转折变化，需选表示情况改变的选项。
4. 第19空：后文举例说明网购的弊端，比如不能试穿、撞款，前文需要引出网购存在问题的表述。
5. 第20空：后文用“Because”解释原因，说明前文是提出疑问“为什么”，找到对应的疑问选项。
【解析】
1. 第16空：根据后文“We have to get around for a long time to find what we need.”可知，此处强调购物花费大量时间，选项D“Shopping always takes a lot of time.”符合语境，故选D。
2. 第17空：前文提到“After we buy some goods, we need to take them home.”，购物后携带商品回家会让人疲惫，选项C“We always feel tired after shopping.”承接上文，故选C。
3. 第18空：前文介绍传统购物的不便，后文引出可以在家随时购物的新方式，选项E“Now, it is not the same.”起到转折过渡的作用，自然开启下文对网购的介绍，故选E。
4. 第19空：后文举例“you can't try on the shirt before you buy it...And you may see many people have the same bags.”都是网购存在的弊端，选项B“But sometimes it may bring some problems.”可以引出这些问题，故选B。
5. 第20空：后文用“Because they all buy the bag online.”解释原因，说明前文是在询问原因，选项A“Do you know why?”符合语境，故选A。
