ANT/ANTI}
{ANT/ANTI} is opposite to or opposes something else. An antiseptic
or an antibiotic fights germs; an anticlimax is the opposite of a
climax; antidote is given against a poison; and an antacid fights
acid in the stomach. Be careful not to confuse anti-with ante-,
meaning "before":antebellum means "before a war," not "opposed to
war."
antagonist \>en't>eg>nist\
A person who opposes or is unfriendly toward another;an opponent.
对手,敌手。
On stage or screen or in a story or novel, the protagonist is
the main character and the antagonist is the opposing one. Pro-
and ant- usually mark the good and bad characters, but not always;
there may instead be an evil protagonist and a good antagonist.
In the drama of the real world, it is especially hard to sort out
which is which, so we usually speak of both parties to a conflict
as antagonists. During a strike, representatives of labor and
management become antagonists; they often manage to antagonize
each other, and the antagonism often remains after the strike is
over.
protagonist:n. 主角
antigen\'>entidjen\
A chemical substance (such as a protein) that, when introduced
into the body, causes the body to form antibodies against it.
[生物]抗原。
Our bodies fight off disease and infection with white blood cells
that recognize antigens on the surface of invading organisms and
produce antibodies to combat them.
The anti- in antigen refers to antibodies, and the -gen means
"producer." So just as an allergen produces an allergy and a
pathogen produces a pathology or disease, so an antigen produces
an antibody, a substance that fights of harmful outside elements.
Antigens are rodlike structures that stick out from the surface
of an invading organism and allow it to attach itself to cells
in the invaded body. But in doing so, they signal the body that
they are present and it immediately goes to work to fight off
the invader.
rodlike: adj. 杆形的,棒形的
