&&&& There are some stories behind English words.
&&&& You've spent a lot of time studying how to use English in a proper way. But have you ever wondered
why English speakers say some of the things they say? For example, why do they say "an easy task" is "a
piece of cake"? Why do the two letters "OK" means "all right"?
&&&& Many English words and phrases have stories behind them. Sometimes these stories can help us look
back into old western history. Let's take a look at a few of the original * common English words and phrases: &&&& &OK
&&&& "OK" was an American who lived in the 19th century. His name was "Old Kinderhook". In one year he was
trying to take the place of the leader of his town. His supporters went around the town shouting" OK \ OK \"
The supporters thought their future leader was" all right". The expression caught on, and now if something is "all right", people like to say"OK"
&&&& Is your boss nice to you? If not, just be glad you weren't living in the old times. Back to that time, bosses
could do anything bad to their men and could even beat* them! That explains why the word "boss" comes from
an old German word meaning"to beat".
&&&& A piece of cake
&&&& A famous American writer named Ogden Nash lived in the 1930s. Many readers enjoyed his poems and
wrote them down in their notebooks. In one of his poems, Nash wrote," Her picture's in the papers now, and
life's a piece of cake." His readers found these words interesting and quickly wrote them down. They thought
that if one picture in a newspaper could make you famous, wouldn't life be easy?
&&&& For nearly 70 years, "a piece of cake" has meant any task or activity that is easy.
1. Some of English words can tell us stories about _________.

高三数学题 求详细解答
1曲线3/x+4/y=1(x&0,y&0)上的点P到直线l：3x+4y=1的距离的最小值
2已知函数fx=e^x+sinx,gx=ax,Fx=fx-gx（1）若x=0是FX的极值点求实数a的值
（2）当a=1/3时，若存在x1，x2属于[0，正无穷大）使得fx1=gx2，求x2-x1的最小值（3)若当x属于[0，正无穷大）时，Fx≥F-x恒成立，求a的范围
第三小题是F（x）≥F（-x）
提问者采纳
1，曲线化为y=4+12/(x-3)y'=-12/(x-3)^2=-3/4解得，x=7,y=7最小距离=9.62，Fx=fx-gx=e^x+sinx-axF'(x)=e^x+cosx-a1）若x=0是FX的极值点求实数a的值e^0+cos0-a=0a=22）当a=1/3时，若存在x1，x2属于[0，正无穷大）使得fx1=gx2，求x2-x1的最小值设x2-x1=m则e^x+sinsx-1/3(x+m)=0m=3e^x+3sinx-xm'=3e^x+3cosx-1，当x&0时，恒为正故当x=0时，m=3即x2-x1的最小值为3，
第三小题呢
很难，问你们老师吧。
帮我想想吧
