We touch our faces all the time, and it had never seemed to be a big problem. A recent study shows, touching our faces-the "T-zone" of our eyes, nose and mouth in particular-can mean giving ourselves the deadly virus.

This is why organizations like the Centers of Disease Control and Prevetion (CDC)have suggested that we should avoid touching our faces. Yet, stopping this "simple" behavior might be harder than you think because it's already fixed into our system. That is to say face-touching is subconscious, which means it's very hard to change "because you don't even know you're doing it", said Sawyer.

But face touching has its functions. Some face touching is an automatic behavior when there is an itch* on your nose, you'll scratch it without thinking. According to CNBC, a 2014 study found that touching your face also helps to reduce stress and regulate mood. For example, you're more likely to do it when you feel nervous or embarrassed. According to Dacher Keltner, a professor at the University of California Berkeley, US, this action may also come with a social function: When you are talking to someone and want to change the subject, for example, touching your face is like "the curtain on a stage, closing up one act of the play, ushering in the next, "Keltner told the BBC.

You can't help touching your face, but you're not alone. In a 2015 study, where a group of medical students were filmed in class, it was found that they touched their faces an average of 23 times an hour-with 44 percent of the touches being in the "T-zone". That was particularly surprising since medical students were supposed to know better.

Since it's hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the virus.

Tips for keeping your hands away:

※ Tie up your hair so your face won't itch because of the stray hair.

※ Keep your hands occupied, e. g. with a stress ball.

※ Ask a friend to keep an eye on your hands.

1.It is hard to stop touching faces because people _________________________.

A.don't take it seriously

B.do it without awareness

C.are born with the behavior

D.feel happier while doing it

2.In Keltner's opinion, touching faces during a conversation probably means ___________.

A.moving on to another topic B.getting an itch in the face

C.showing an interest it in the subject D.feeling nervous about the talk

3.Who is doing right to keep hands away from faces?

A.John usually puts his hands on the nose

B.Tony relaxes himself by holding stress balls.

C.Sally gets her hair down even in hot summer.

D.Mary advises her friends to do eye exercises.

4.Which of the following is true according to the passage?

A.It's harmful to touch our faces frequently.

B.Touching the T-zone will make you die soon.

C.More medical students should take part in the study.

D.Washing hands more often helps stop touching faces.

From video games and museums to medical training, VR（virtual reality, 虚拟现实）has been changing our lives for the better. However, this wonderful new technology has a so-far unsolvable problem: It may make people feel sick from the VR experience. The feeling of sickness, caused by VR, is called cybersickness.

"With modern VR systems, the possibility of cybersickness after only 15 minutes' experience is from 40 to 70 percent," Thomas Stoffiregen, a researcher at the University of Minnesota, US said. This sickness is probably caused by sensory conflict （感觉冲突），explained Stoffregen. When you are wearing a VR headset, your body's motion sensors cannot match the information received by your eyes. For example, when we wear a VR headset and ride a virtual roller-coaster, we think we are going up and down, but our bodies stay still. It leads to the loss of balance. Sickness is from our bodies' natural reaction to the experience. Adding to this problem, women are more likely to feel sick from the VR experience than men.

According to a study by Bas Rokers, a scientist at the University of Wiscons in-Madison, US, one reason could be the headsets. To work properly, VR headsets must match up with your PD （pupil distance, 瞳距）. Since they are designed larger PD, not everyone gets the best experience. Rokers found the larger PD distance is, the greater discomfort will cause. Based on his studies, about 90 percent of women have a shorter PD than the headset is made and that's the reason why women are more likely to have cybersickness.

Cybersickness prevents the widespread use of VR technology. Once it becomes comfortable and easy to use, however, it could play a great role in our lives.

1.Which is Right about cybersickness?

A.It's a common problem with VR technology. B.It is caused by one's poor sense of direction.

C.It's more possible for young people to feel sick. D.It only happens to women and children.

2.The example of riding a virtual roller-coaster is used to _________.

A.tell what it is like to have cybersickness B.explain how cybersickness is caused

C.tell people how to avoid cybersickness D.show how cybersickness influences people

3.Why are women more likely to have cybersickness?

A.They have a poor sense of direction. B.VR headsets are only made for men.

C.VR headsets are too large for their PDs. D.They are easy to lose balance.

4.What does the writer think of the VR technology?

A.The VR technology has already played a great role in our lives.

B.There is still something to do before VR technology plays a great role.

C.The VR technology is comfortable and easy to use for everyone.

D.It's impossible for VR technology to be popular in the future.
