[解析]
(1)语境衔接题。根据前文Although most empty plastic bottles are thrown,there are actually many other ways you can reuse them other than drinking(虽然大多数空塑料瓶都被扔了,但实际上除了喝水,还有很多其他的方法可以重复使用它);以及后文Here are some interesting tips to use with empty plastic bottles(以下是一些使用空塑料瓶的有趣技巧),可知G选项"它们允许你创造性地回收用于各种目的"承接上文空塑料瓶的话题,引出后文的技巧,其中They指代上文的many other ways。故选G。
(2)联系上文题。根据前文When making biscuits,did you just realize you didn't have any tools to cut them?You just need a small or large plastic bottle depending on your needs.First cut the bottle into half(在做饼干的时候,你是不是突然意识到你没有任何工具来切割它们?你只需要一个大小取决于你的需要的塑料瓶。首先把瓶子切成两半)可知,F选项"然后再用其中的一半来切饼干"承接前文,介绍第二个步骤。故选F。
(3)联系上文题。根据前文Do you find it challenging to separate eggs(你觉得分离鸡蛋很有挑战性吗)可知,D选项"你可以用塑料瓶来解决这个问题"为对于前文提到问题的回答,符合语境。故选D。
(4)主题判断题。根据下文Want to remove flies in your garden safely?Use plastic bottles.Cut the bottle into half and place a sweet syrup(糖浆) at the bottom.Then place the top in the bottom so that the bottle mouth faces down.The fly will be attracted to the smell and fly into the bottle hole(想要安全地清除花园中的苍蝇?使用塑料瓶。把瓶子切成两半,在底部放上糖浆。然后把瓶盖盖在底部,使瓶口朝下。苍蝇会被气味吸引,飞进瓶子洞)可知,A选项"陷阱"很好地概括这一段内容﹣﹣﹣塑料瓶可以用来做苍蝇的捕捉器陷阱,可以作为本段的主题句。故选A。
(5)联系下文题。根据后文Then,place the bottle with ice on the floor for a high fan.Put the fan behind the bottle and the fan will blow the cold air as the bottle with ice causes the temperature to be lower(然后,把装有冰的瓶子放在地板上,这样就可以用高功率风扇了。把风扇放在瓶子后面,因为装有冰的瓶子会使温度降低,所以风扇会吹出冷空气)可知,E选项"把两个大瓶子装满水,然后变成冰"可以引出后文,the bottle with ice是关联词。故选E。
