The Year of the Dog has gone and this year we have words can we think of for pigs?
Some bad words maybe,like silly,dirty,greedy(贪婪)…But,are these true?
When we see pigs,they are usually in dirty water or behind dirty pigs also want to
be clean if they have no sweat glands(汗腺),SO they have to get cool in water when they
feel hot.
If people are greedy,we say they“pig out”.Yes,pigs love eating a they are useful to
not only eat their also use other parts of skin is used for glue and
hair can be used to make brushes. Sometimes,pigs are even used to make medicine.
“He is as silly as a pig!”This expression is are very smart all are the third cleverest--monkeys,dolphins and think the training of pigs is easier than the training of dogs and have a very good sense of smell(嗅觉).They can find things nearby or can also help the police to—sniff—out drugs(毒品)at an airport or at a train station 1
7 this writer mainly wants to tell US that——•
are always very silly,dirty and greedy
are as clever as monkeys and dolphins
’S ideas about pigs are not always correct
72. Pigs usually like to stay in water in hot weather because they can there.
themselves water cool
of pigs can be used to make glue.
training of pigs is easier because .
are smarter than dogs and cats
can do everything easily
have a very good sense of smell

【25】如图,在△ABC中,∠ACB=90°,O是边AC上一点,以O为圆心,OA为半径的圆分别交AB、AC于点E、D,在BC的延长线上取点F,使得BF=EF,EF与AC交于点C:
(1)试判断直线EF与☉O的位置关系,并说明理由;
(2)若OA=2,∠A=30°,求图中阴影部分的面积;
【解答】
(1)EF是⊙O的切线。
证明:
连接OE,
∵OA=OE,
∴∠A=∠AEO,
∵BF=EF,
∴∠BEF=∠B,
∵∠ACB=90°,
∴∠A+∠B=90°,
∴∠AEO+∠BEF=90°,
∴∠OEF=180°-(∠AEO+∠BEF)=90°,
∴EF是⊙O的切线。
(2)解:
∵∠A=30°,
∴∠EOG=60°,
∵∠OEG=90°,
∴∠EGO=30°,
∴OG=2OE=4,EG=2√3,
S△OEG=1/2OE×EG=2√3,
S扇形ODE=1/6π×2²=2π/3,
阴影面积=S△OEG-S扇形ODE=2√3-2π/3.
