Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when wβfinally clean up our act.
If the evidence for how wrong the first idea is isn’t apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?
To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.
The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.
The effects of some bad habits-smoking, in particular-can haunt you for decades. But the damage from other habits can be largely healed.
“Any time you improve your behavior and make lifestyle changes, they make a difference from that point on.”says Dr. Jeffey Koplan.“Maybe not right away. It’s like slamming on the brakes. You do need a certain distance.”
But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research: ---A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month. ---The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won’t cure all that bothers you, of course. But doctors believe that many chronic diseases-from high blood pressure to heart disease and even some cancers-can be warded off with a few sensible changes in lifestyle.
Not sure where to start? Surprisingly, it doesn’t matter, since one positive change usually leads to another. Make enough changes, and you'll discover you’ve adopted a new way of life.
1.Most people with bad habits of eating more than they should believe that　　　　　 .
A.their bodies cannot be damaged by the bad habits
B.they can force themselves to clean up the had habits later
C.their bodies can heal all the damage without the help from outside
D.they can never change the habits that have developed for decades
2.The evidence against the assumption that we are indestructible　　　　　 .
A.is seldom apparent B.is clearly shown in the mirror
C.is still a question D.will appear obvious sooner or later

A.women should eat as much fish as possible
B.men don’t have to eat as much fish as women
C.eating a little more fish can improve women’s health
D.women are at a higher risk of suffering a stroke than men

We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.
A brain can also simply be a smart person, If a person is called brainy, she is smart and intelligent. If a family has many children but one of them is super smart, you could say, "She's the brains in the family." And if you are the brains behind something you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.
Brain trust is a group of experts who give advice. Word experts say the phrase "brain trust" became popular when Franklin D. Roosevelt first ran for president in 1932, Several professors gave him advice on social and political issues facing the US. These professors were called his "brain trust."
These ways we use the word "brain" all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain." As a verb to drain means to remove something by letting it flow away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.
However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.
If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.
1.According to the text, if you're the CEO of Bai Du you can be called
A. the organ of Bai Du
B. Bai Du's brain trust
C. the brain drain of Bai Du
D. the brains behind Bai Du
2.Why did Roosevelt successfully win the election?
A. Because he was smart at giving advice.
B. Because word experts were popular.
C. Because he got his brain trust.
D. Because he was the brains behind America.
3.Which of the following expression is always used in a negative way?
A. Brain trust　　　　　 B. Brain drain
C. Brainwash　　　　　 D. Brainstorm
