   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 U. S.
    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.

    Mars( 火星) appears to be flowing with small streams of salty water, at least in the
summer, scientists reported Monday. "It suggests that. it would be possible for there to
be life today on Mars," NASA's science mission chief, John Grunsfeld, said at a news
conference on September 28, 2015.
      The streams are about 12 to 15 feet wide and 300 feet or more long, scientists said.
"What we're dealing with is wet soil. thin layers of wet soil, not standing water," said
Aifred  McEwen of the University of Arizona at Tueson ! the principal scientist for the
Mars Reconnaissance Orbiter's high-resolution imaging experiment.
      Because liquid water is essential to life, the findings could have major implications
for the possibility of Martian life. The researchers said further exploration is needed to
determine whether microscopic life exists on the planet.
     The presence of liquid water could also make life easier for astronauts visiting or
living on Mars. Water could be used for drinking and for creating oxygen and rocket
fuel.  NASA's goal is to send humans there in the 2030s.
     The evidence of flowing water consists largely of dark, narrow streaks(条痕) on
the surface that tend to appear and grow during the warmest Martian months and fade
the rest of the year.
     Mars is extremely cold even in summer, and the streaks are in places where the
temperature is as low as minus 10 degrees Fahrenheit.  But salt can lower the freezing
point of water and melt ice.
     The source of the water is a mystery. Scientists noted it could be melting
ice.  It could be an underground aquifer, which is rock or sand that can hold water.  It is
possibly water vapor from the thin Martian atmosphere, Or it may be a combination
Michael Meyer, lead scientist for NASA's Mars exploration program, said the only
