23.解:(1)四边形BEFE是正方形,理由:由旋转可知
∠E=∠AEB=90°,∠EBE=90°,BE=BE.又:
∠FEB=90°,.四边形BEFE是正方形.(2)证
明:如图,过点D作DH⊥AE于点H,则∠DHA=
90,∠1+∠3=90.:DA=DE,AH=2AE.
四边形ABCD是正方形,.AB=DA,∠DAB=90°,
∠1+∠2=90°,.∠2=∠3.:∠AEB=∠DHA

(3)DE=3√I7解析:如图,由题得△ADH≌
△BAE≌△BCE,∴.AH=BE=EF.CF=3,
AE=CE'=3+EF=3+BE..AB*=AE+BE

Dear editor,
I've just read an article in a newspaper about sav-
·88·
ing tigers.It says that the number of tigers is becoming
smaller and smaller in our country.It's terrible.I saw a
few people sell bones of tigers by the roadside the other
day.I also learned that some people killed tigers in order
to make money.And too many trees have been cut
down.The places where tigers used to live were de-
stroyed.Tigers are in danger of dying out.
Our government should punish the hunters.We
should try our best to make our earth pleasant and
peaceful,not only for human beings but also for ani-
mals.
Yours faithfully,
Li Hua

Children everywhere love toy bears,and people have been making them for hundreds
of years.They also like stories about young bears.Three of the most famous storybook
bears are Rupert Bear,Pooh Bear,and Paddington Bear,and most children in Britain and
America also know the story Goldilocks and The Three Bears.At the moment so many
children-and adults too-like toy bears and there are shops that sell only toy bears of all
kinds.
Many people call toy bears "Teddy"although this name has been used only since the
beginning of the 20th century.The word "Teddy"comes from Theodore and a man called

called their own bears Teddy,too.

unless young
Just look at how much young writers like Han Han and Guo Jingming are loved,we
may know writing has become a fashion among today's teenagers.
Gao Can,a 13-year-old girl,is the 46 member of the Association of Writers of
Shaanxi.She writes fairy tales,short 47,and most of all,poems.Gao said she began
poem writing when she was in primary school.Once the teacher asked the class 48 a
composition called "If I were ..."Gao had an idea,"Why not make it a poem?"That was
her 49 poem,and it won a lot of compliments from both her teacher and her
classmates.So far,hundreds of her poems 50 out.
"Writing poems is not difficult at all.Just express 51 -what you do,what you
see or what you think,said Gao."I don't have enough life experiences,so I write about

nature,about things I feel inside."
However,teenagers these days seldom write poems or read them because exams want
any kind of articles 52 poems.
But like Gao,there are still students who like poems.Hu Jingzhi is one of them.The
14-year-old boy said he was 53 in poem writing.But it was annoying that he couldn't
find many poem collections in nearby bookshops.
Gao agreed with Hu.She said today's bookshops 54 with books on "how to give
a successful speech'”,“how to know what others think'”or“how to make money55”.
"Poems won't teach you how to make money,but the beautiful words clear your mind
and activate your imagination,"said Gao."At least read poems-for the nice things in
life.”
