Quantum Communication （量子通信） - Cutting-edge Technology
What is quantum communication？The scientific world defines it as a "method of communication using quantum effects on communications cycles." （1）CC This technology has grown originally from encrypted messaging and is virtually unbreakable.
You might ask：How are messages sent by quantum encryption safer？It is because particles of light cannot be divided.An eavesdropper cannot divide a particle of light into two parts，nor can a message in a particle of light be read by a third party or transmitted elsewhere. （2）BB So quantum physics can protect such secret codes，as they can neither be intercepted nor cracked.
Now you can appreciate the unlimited power of quantum communication. （3）EEAnd it has achieved results attracting world attention.Among these achievements is the immortal work of Pan Jianwei，Chinas youngest academician.
The fruit of Academician Pans scientific research into quantum communication was chosen as one of "Ten Worldwide Science and Technology Advances" in 1997. （4）FF
On Aug.16，2016，China launched a quantum communication satellite it had developed and built itself，making China one of the quantum-communication-producing countries.There are many applications for quantum communication-military，defense，data encryption，telecommunications，insurance，securities，industry and finance. （5）AA Quantum communication is a powerful promoter of the continuous advance of science and technology worldwide.
A.They all need this kind of advanced technology.
B.Such message may be detected，but it cannot be understood.
C.Simply put，it is a method of encrypted communication.
D.Is it so miraculous？If you don't believe it，let us tell you a story.
E.China has poured a huge amount of effort into research in this field
F.His research put China in the leading place in the world in quantum communication.
G.Many Chinese scientists have devoted themselves wholeheartedly to making great contributions.

3．Dear Laura，
Thanks for letting us to stay at your seaside house． Now， you might have heard from your neighbors about which happened on Saturday evening． When I was out a walk， my younger son， Tom， played football before your house． He made so many noise that the neighbors got quite angrily． Even worse， Tom broke one of the window of Mr． Wilson's house． Tom and I apologized to all the neighbors for the unhappy happenings， but promised to have the broken window repair soon． Tom said that we would not do such silly things any more． I am glad that your neighbors had forgiven us． They are really nice people．
Yours，
