[简答题]Do you ever feel angry about someone who stands too close, talks too loudly or makes eye contact for too long Why do we feel uncomfortable with those “close talkers” Or with strangers who stand very near to us in a line
Scholars began to study personal space decades ago. They found that humans tend to avoid eye contact if they feel someone is standing too close. They put a distance between themselves and strangers.
According to scientists, personal space involves not only an imaginary space around the body, but around all the senses. People may feel their space is being violated when they encounter an unwelcome sound, scent or stare: the woman on the bus shouting into her mobile phone or the co-worker sitting next to you putting on some perfume you don’t like.
Whether people in recent times have become more protective of their personal space is hard to say. Yet studies of airlines show passengers’ strong desire to have some space to themselves.

A. A．unsafe
B．uneasy
C．alert
D．curious

[单项选择]
If you didn’t sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn’t nap (打盹，小睡) after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day.
You should get out of the habit of sleeping during the evening. Right after your evening meal, engage in some sort of physical activity—a sport such as bowling, perhaps, or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good night’s rest without taking a pill.
If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up a
A. to take sleeping pills
