Question

【题目】根据短文内容，从短文后的七个选项中选出能填人空白处的最佳选项。选项中有两项为多余选项。

Your smart phone may have hurt you before you realize it. Don’t be addicted to it. Put your phone away, OK?

Cyber(网络) Sickness

Also called “digital motion sickness”, symptoms that range from headaches to woozy(头昏眼花的) feelings can occur when you quickly scroll on your smart phone or watch action-packed video on your screen.【1】Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don’t agree, that’s when you feel dizziness and sickness.

Text Claw

It is the unofficial term for soreness and muscle contraction(收缩) felt in the fingers, wrist and forearm after heavy smart phone use. 【2】So if you’re always on your phone, it makes sense to feel discomfort in your hands and forearms.

Eye Strain(疲劳)

Do you stare at a screen for hours on end? If you’re reading this, you very well might. 【3】Staring at your digital devices for a long time can lead to dry eyes, headaches and tiredness, which can decrease your productivity. Experts suggest taking screen breaks every 20 minutes.

Text Neck

Similar to the claw, text neck—discomfort in the neck and spine—happens when you spend a long time looking down at your smart phone. 【4】Being mindful of how far your neck bends when you’re on your phone—and bending it back to an upright position—can help reduce the risk of text neck.
