Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(證據(jù)) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎癥)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(鍛煉)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑潤的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

Never argue with one's own understanding.

The whisper of intelligence is always there, whatever you do.

If you create a time lag (隔絕層) between the whisper of intelligence and understanding in you and your action, then you are preventing the brain from growing into a new size. When you argue with intelligence, when you postpone acting according to understanding then there is confusion, the brain gets confused.

The voice of understanding, the voice of intelligence has insecurity about it. How do you know that it is the right thing?

So we tend to ignore it. Instead we accept authority. We obey.

But the brain cannot be orderly, competent, accurate and precise if you do not listen to it, if you have no respect. We are so busy with the outside world and its force that the world that is inside us does not command that respect and reverence (敬重), that care and concern from us.

So one has to be a disciple (信徒) of one's own understanding, and look upon that understanding as the master.

Sometimes one may commit a mistake, it might be the whim (念頭) of the ego and we might mistake the whim, the wish of the ego for the voice of silence and intelligence, but that we have to discover. Unless you commit mistakes, how do you learn to discriminate between the false and the true? In learning there is bound to be a little insecurity, a possibility of committing mistakes. Why should one be terribly afraid of committing mistakes?

So instead of accepting the authority of habits and conditionings, while one is moving one watches, and when there is a suggestion, do not neglect, ignore, or insult the whisper from within and from one's own intelligence.

1.What will happen if you refuse to follow your own understanding according to the above passage?

A．Your brain will become smaller.

B．You will never get help from authority.

C．You will hardly know the world.

D．Your own intelligence will stop growing.

2.What is the function of committing mistakes from the view of the author?

A．Mistakes can make one practical.

B．Mistakes can make one know the facts.

C．Mistakes can allow one more time to develop.

D．Mistakes can improve one’s judgment.

3. The whole passage is developed by ______.

A．facts and ideas                         B．reasoning and explaining

C．scientific experiments                    D．a(chǎn)rguing and debating

4.The best title of the passage might be ______.

A．Never argue with your own understanding

B．Never believe any authority while arguing

C．Never neglect whispers from around you

D．Never stop training yourself.
