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.

1．Walk Out of the Comfort Zone and Try New Things For most high school students，free periods （課、節(jié)） are useless.From what I have seen，few do homework. （1）
.This makes it impossible for those who actually want to do work to complete any.As a senior next year，I think extra periods should be used to take optional subjects.
（2）.Now is the time for us students to choose a suitable one.We will experiment in different fields of study.We will never know if we are interested or talented in a subject if we don't try it.
In my 8th grade，I was told that I had to take an art class as a graduation requirement；so in the 9th grade I took Studio and Art.One of the projects was to build a clay pot，but I built mine incorrectly，so it broke in the kiln （窯）. （3）.Now I know for sure that I do not want to be an artist.However，the class was one of my favorites that year.I was able to try new activities and test my ability.
（4）!College is when we should focus on a specific major，but high school is when we have to figure it out.
Half of all college students change their major at some point.By doing that hundreds of dollars are wasted on classes that they would have never needed to take.So use our extra periods to find out what we want to do in college. （5）.
A.Our school offers many classes
B.We should find out what we are good at
C.I've avoided anything related to art since then
D.Instead，many are on their phones and talking
E.I found out that I have no artistic ability at all
F.Walk out of our comfort zone and try new things
G.The classes we choose can influence us in the future發(fā)布：2025/1/1 18:0:1組卷：7引用：5難度：0.5 -
2．Most smart phones allow you to run location-sharing software that uses the phone's GPS capability to let friends and family know your exact location．There are lots of great uses for this technology．（1）
So make sure you're permitted to use an app or service，and pay attention to how you are using it．Here're some important points you may find helpful．
