Day 9

___1__ While these compulsive( 无法控制的) actions may appear to be irrational or

pointless, and may even result in negative consequences, the individual experiencing the

compulsion feels unable to stop him or herself.

The compulsive behavior can be a physical act, like hand washing, or a mental activity, like

counting objects. When an otherwise harmless behavior becomes so consuming that it negatively

impacts oneself or others, it may be a symptom of obsessive-compulsive disorder (OCD)(强迫症).

___2___The former is an overwhelming desire to do something, while an addiction is a

physical or chemical dependence on a substance or behavior. People with addictions will continue

their addictive behavior, even when they understand that doing so is harmful to themselves and

others. ___3___

Unlike compulsions and addictions, which are acted out uncontrollably, habits are actions

that are repeated regularly and automatically.

Habits typically develop over time through a natural process called “habituation,” during

which repetitive actions that must be consciously initiated eventually become subconscious and

are carried out habitually.

While there are good habits and bad, unhealthy habits, any habit can become a compulsion or

even an addiction. ___4___ For example, the good habit of exercising regularly can become an

unhealthy compulsion or addiction when done to excess.

Common habits often develop into addictions when they result in a chemical dependency, as

in the cases of smoking. The habit of having a glass of beer with dinner, for example, becomes an

addiction when the desire to drink turns into a physical or emotional need to drink.

___5___While we can choose to add good, healthy habits to our routines, we can also choose

to break old harmful habits.

A. A compulsion is different from an addiction.

B. It currently affects about 1 in 40 adults and 1 in 100 children in the U.S.

C. Some of these behaviors are visible actions while others are mental behaviors.

D. In other words, you really can have “too much of a good thing.”

E. Compulsive behaviors are actions that a person feels “compelled” or driven to do over and

over again.

F. Alcoholism, smoking, and gambling are perhaps the most common examples of addictions.

G. Of course, the key difference between a compulsive behavior and a habit is the ability to

choose to do them or not.

What will man be like in the future—in 5000 or even 50, 000 years from now? We can only

make guesses, of course, but we can be sure that he will be different from what he is today, for

man is slowly changing all the time.

___1___ Man, even five hundred years ago, was shorter than he is today. Now, on

average, men are about three inches taller. Five hundred years is a ly short period of time, so we

may assume that man will continue to grow taller. Again, in the modern world we use our brains a

great deal. Even so, we still make use of only about 20% of the brain’s capacity. As time goes on,

however , we shall have to use our brains more and more, and eventually we shall need larger

ones! This is likely to bring about a physical change too: the head, in particular the forehead, will

grow larger.

___2___ In fact, we use them so much that very often they become weaker and we have to

wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.

On the other hand, we tend to make less use of our arms and legs. ___3___ At the same time,

however, our fingers will grow more sensitive because they are used a great deal in modern life.

But what about hair? This will probably disappear from the body altogether in course of time

because it does not serve a useful purpose any longer. ___4___

Perhaps all this gives the impression that future man will not be a very attractive creature to

look at! ___5___ All the same, in spite of all these changes, future man will still have a lot in

common with us. He will still be a human being, with thoughts and emotions similar to our own.

A. This may well be true.

B. Let us take an obvious example.

C. Nowadays our eyes are in constant use.

D. These, as a result, are likely to grow weaker.

E. Now how exactly will this great revolution occur?
