Ⅰ.阅读理解
1．C 考查细节理解。根据When t fly部分的第二句可知，在美国，买机票最便宜的日子通常是星期二、星期三和星期六，故C项正确。
2．B 考查词义猜测。根据画线短语所在部分的小标题可知，该部分是建议游客买机票时要作比较，并结合画线短语所在句可知，此句是说抑制住你不作任何比较就去你最喜欢的航空公司网站买机票的冲动。B项意为“抑制住做某事的欲望”，故B项符合文意。
3．D 考查推理判断。根据第一段可知，如果你明年要休假并打算乘飞机旅行，这里有一些有用的购买便宜机票的建议，故可推知，本文是写给那些寻找最佳机票价格的人，故D项正确。
4．C 细节理解题。根据第一段最后一句话“It might be，mainly because as we stare at ur devices we are expsing urselves t blue light.”可知，我们在盯着电子设备的同时，就使自己暴露于蓝光下。故答案为C项“它可能来自电子设备”。
5．B 细节理解题。根据第二段第二句和第三句“While it's true that light can damage ur eyes under certain circumstances, there's n scientific evidence suggesting that blue light is harmful t ur eyes.But many peple still think it is，which is why blue lightblcking glasses are s ppular.”可知，虽然在某些情况下光线确实会损伤我们的眼睛，但是并没有科学证据表明蓝光对我们的眼睛有害。不过许多人仍然认为蓝光有害，这就是防蓝光眼镜如此受欢迎的原因。故选择B项。
6．A 推理判断题。根据第四段前三句“Blue light expsure is nthing new.In fact，the sun is the largest surce f blue light. Mrever，blue light is als present in LED lights.”可知，蓝光照射并不罕见。事实上，太阳就是蓝光最大的来源。此外，蓝光也存在于LED灯中。也就是说蓝光照射几乎是不可避免的，答案为A项。
7．C 推理判断题。根据最后一段最后一句“S if eyestrain is the real issue，blue lightblcking glasses are prbably f little use.”可知，如果眼疲劳才是真正的问题，那么防蓝光眼镜可能是无用的(useless)。
Ⅱ.七选五
1．D 逻辑分析题。本题考查考生理解段内过渡句的能力。上文讲在2020年，我们大多数人都在家里度过了很长的时间；下文讲这里有一些可以使你的家变得更适合你的身体和心灵(成长)的方法。D项“或许你已经意识到一个健康的家庭(环境)的重要性了”承上启下，符合语境。故选D。
2．E 逻辑分析题。本题考查考生理解段内衔接关系的能力。根据本段第一 句“Take ff yur shes at yur dr.”可推知，本段陈述的是在屋内换鞋的必要性。E项“在家门口留一双你在家中穿的鞋子”符合语境。故选E。
3．C 例证题。本题考查考生理解段内例证句的能力。上文讲如果你家里的墙壁让你有种包围感，也许是时候选一种新的墙漆了；下文具体解释了红蓝两种颜色的具体影响。C项“研究表明，颜色可以影响你的心情”承上启下，符合语境。故选C。
4．A 主旨题。本题考查考生总结归纳的能力。下文讲一项小调查表明，与人工灯源相比，在自然光源下工作的人们没那么困倦，且他们在与心理过程有关的测试中表现得更出色。由此可推知，本段内容应与“在自然光源下工作”有关。A项“在窗边工作”符合语境。故选A。
5．G 逻辑分析题。本题考查考生理解段内句子之间逻辑关系的能力。上文讲清洁你的房子中的空气；下文讲能源部门表示它可以移除空气中99.97%的污染物和微粒。高效的空气过滤器可以清洁一个单人间或整个房子。G项“这个黄金标准就是一个高效率的空气微粒过滤器”承上启下，符合语境。故选G。
