You have the basics down:doing laundry, keeping the bathroom clean, wiping the kitchen countertops-but dirt and grime have a bad habit of collecting in the strangest places, including the ones you don't think to look. 1
Clean off doorknobs and handles
You probably don't think to clean off the doorknobs and handles around your home very often. 2 When you think about how often we touch the doorknobs and handles in our homes, especially with dirty hands or on the way in or out of the bathroom, you may even choose to make a habit of it.
3
Considering how often we use our phones, and where we use them, our phones deserve a more thorough cleaning from time to time. Keeping your device clean works in your favour in other ways too- it keeps your screen clean and easy to read. 4 Wash your pillows
You may not know it, but most pillows are designed to be machine washable. And it's a good thing too, considering pillows tend to be exactly where dead skin, dust, drool and in many cases, dust mites love to hang out. 5 For people with compromised immune systems or who have allergies, they can be an irritant that makes for sleepless nights, skin imitation and sinus congestion(鼻窦堵塞）.
A. Clean your screen
B. Wipe off your smartphone
C. When's the last time you did more than just wipe off you smartphone's screen when it was too smudged to see through
D. Also it keeps dust and grime out of speaker grates, away from charging ports and out of headphone jacks.
E. For most people, that's not a huge deal, aside from the fact that they're putting their face on a dirty pillow at night to sleep.
F. But they're worth a quick wipe the next time you're cleaning in the same room.
G. Here are some spots around your house you should consider cleaning more often.

D. Also it keeps dust and grime out of speaker grates, away from charging ports and out of headphone jacks.

F. But they're worth a quick wipe the next time you're cleaning in the same room.
G. Here are some spots around your house you should consider cleaning more often.
1.【答案】G
【解析】根据上一句中的“but dirt and grime have a bad habit of collecting in the strangest places, including the ones you don't think to look"可知，该空可引出本文主题：家中一些你应该考虑更频繁清理的地方。
2.【答案】F
【解析】前文介绍的是“你可能没想过要非常频繁地清洁家中各处的门把手”，F项中的they指代上一句中的"the doorknobs and handles",故该空应选F项（但下次打扫同一个房间时，有必要顺便擦拭一下它们）。
3.【答案】B
【解析】此空为小标题，从下文“our phones deserve a more thorough cleaning from time to time"可知，需要清理的是“smartphone”。
4.【答案】D
【解析】前文介绍的是保持手机的清洁还会带来其他好处，根据“it keeps your screen clean and easy to read”可知选D。
5.【答案】E
【解析】根据下文提到的“For people with compromised immune systems or who have allergies, they can be an irritant"可知，对免疫功能不全或有过敏症的人来说，脏枕头不好。所以推断前一句应为“For most people,thatapos;s not a huge deal...”，即对多数人来说，这没多大关系。故选E。

2.【答案】F
【解析】前文介绍的是“你可能没想过要非常频繁地清洁家中各处的门把手”，F项中的they指代上一句中的"the doorknobs and handles",故该空应选F项（但下次打扫同一个房间时，有必要顺便擦拭一下它们）。
3.【答案】B
【解析】此空为小标题，从下文“our phones deserve a more thorough cleaning from time to time"可知，需要清理的是“smartphone”。
4.【答案】D
【解析】前文介绍的是保持手机的清洁还会带来其他好处，根据“it keeps your screen clean and easy to read”可知选D。
5.【答案】E
【解析】根据下文提到的“For people with compromised immune systems or who have allergies, they can be an irritant"可知，对免疫功能不全或有过敏症的人来说，脏枕头不好。所以推断前一句应为“For most people,thatapos;s not a huge deal...”，即对多数人来说，这没多大关系。故选E。
