Question

【題目】We all know what a brain is．Adoctor will tell you that the brain is the organ of the body in the head．Itcontrols our body's functions, movements, emotions and thoughts．But abrain can mean so much more．
A brain can also simply be a smartperson, If a person is called brainy,she is smart and intelligent．If a family has many children but one ofthem 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 developingor organizing something．For example, Bill Gates is the
brains behind Microsoft
Brain trust is a group of experts whogive advice．Wordexperts say the phrase
"brain trust" became popularwhen Franklin D．Rooseveltfirst ran for president in
1932, Several professors gave him advice on social and political issues facingthe U．S．
These professors were called his "braintrust．"
These ways we use the word"brain" all make sense．But other ways we use the
word are not so easy to understand．Forexample, to understand the next brain
expression, you first need to know theword “drain．"As a verb to drain means to,
remove something by letting it flow away．So abrain 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．Thebrains are, sort of, draining out of the country．
However, if people are responsible for agreat idea, you could say they brainstormed it．Here, brainstorm is not an act ofweather．Itis a process of thinking creatively about a complex topic．Forexample, business leaders may use brainstorming to create new
products, and government leaders maybrainstorm to solve problems．
If people are brainwashed, it does notmean their brains are nice and clean．To brainwash means to make someoneaccept new beliefs by using repeated pressure in a forceful or tricky way．Keep inmind that brainwash is never used in a positive way．
