中西方喜爱的数字
“一”是最小的自然数，在中国，由“一”组成的成语数不胜数。如：
视某人或某物高尚、珍贵的如独一无二、一刻千金等；对人或物有深厚感情如一往情深等；指做事认真、仔细，一点儿不马虎，如一丝不苟、一心一意等。
西方人对数字“1”也很崇尚，例如：They
fell
in
love
at
first
sight.
(他们俩一见钟情）；A
stick
in
time
saves
nine.(及时一针胜过事后九针）。另外，在整百整千的后面加“1”表示程度更深，如：Don’t
worry.
We
have
a
thousand
one
way
to
do
it.（不必发愁，我们有许多方法可以做到的）。
因其发音与“发”谐音，数字“八”已成为中国人最青睐的数字。汉语中带“八”的成语也不少，如八拜之交，八斗之才，八方支援等都带有不同程度的赞扬之意。
西方人对“8”也充满喜爱。从形状上看，“8”字是由两个“0”组成
的，它象征着稳定、友谊、和谐和完备，而横写的“8”字与数学中表示无穷的符号“∞”相似。因此，教字“8”又暗示着成功、幸福和满足。
二者意义相加，就是幸福绵绵无穷尽。
