Medical Practices in Ancient Egypt
Learning from the Dead
To find out why people have died,today's medical examiners perform autopsies（尸体解剖）．They cut open the body and study its parts.Ancient Egyptians also performed autopsies to help understand causes of death.In addition,autopsies helped ancient Egyptians study the human body.By comparing the hearts of people who were different ages,for example,Egyptians could determine what a young,healthy heart was supposed to look like.
Keeping a Written Record
The Egyptians not only studied the human body,but they also kept detailed records of what they discovered.They wrote and drew their observations on papyrus,a form of paper.The papyrus records became the medical textbooks of that time.Their observations allowed Egyptian doctors to share their knowledge,including how to treat various diseases.
Edwin Smith Papyrus
In 1862，an American named Edwin Smith purchased a medical papyrus in Luxor,Egypt Smith was not a medical expert,but he knew a lot about old documents.He knew that what he had found was valuable.The papyrus turned out to be an ancient textbook on surgery.The papyrus was probably written around 1600 BC，but it was based on information from a thousand years before that.The papyrus presents the information as case studies,including an analysis of how patients survived or died.
（1）By performing autopsies,ancient Egyptians could ．
A．determine the causes of illnesses
B．learn about different body parts
C．keep detailed records on textbooks
D．share what they had discovered
（2）The document bought by Edwin Smith was valuable because it was ．
A．originally written on papyrus
B．an ancient medical textbook
C．discovered by a medical expert
D．written a thousand years before
（3）This article is probably from ．
A．a story book
B．a health leaflet
C．a medical magazine
D．a biology textbook
12．（7.5分）You wait 50 years for a flying car,and then three come along at once.First up is Vahana：an airbus project to develop batterypowered,single-seater aircraft,designed to follow predetermined routes,only changing directions to avoid accidents.Propellers（螺旋桨）on the wings will let it take off and land without a runway.
Second,Dubai recently announced plans to use self-controlled air taxis as a way to beat the terrible traffic jams.The Volocopter is an electric multi-copter with 18 propellers and a fully self-controlled system.It's essentially a self-controlled aircraft with two seats and up to 30 minutes of flying time.
But,if you want something more like the flying cars of 1950s science fiction,try Urb
an Aeronautics' Fancraft.The Israel-based company wants to realize the dream of "an aircraft that looks like the classic vision of a flying car：doesn't have a wing,doesn't have a propeller that can be seen,and can fly exactly from point to point," says Janina Frankel-Yoeli,Urban Aeronautics' vice president of marketing.Earlier flying cars needed runways to take off and land which was,as Frankel-Yoeli says,"not much better than owning a car and an aircraft." To go from point to point requires vertical take-off and landing,but for many years that could only be done by helicopters or larger aircraft.Urban Aeronautics' solution is to use light but powerful engines,lightweight materials,and a self-controlled system.Their fan design-propellers housed in some special tubes-is powerful but unstable,so the Fancraft would be challenging for a human to fly without any help.Instead,computer-aided control technology takes over the tiny,quick changes required to keep the car stable at speeds of 160km/h or more.
But don't be glad too early yet.The main problem to a sky full of flying cars is rules.Not only will every aircraft need to pass strict safety tests,but a new system of so fell autumn rain
air traffic control will be needed to deal with 3-D traffic jams above people who are not aware of what is happening in the sky.NASA is already working on that.Tests have shown that multiple unmanned（无人的） flying cars can communicate with each other to avoid accidents.In the meantime,flying cars will mainly be reserved for emergency services and a few VIPs.
（1）Vahana is different from the Volocopter in that ．
A．it is power-free
B．it is self controlled
C．its routes are fixed
D．its propellers can be seen
（2）The underlined word "vertical" in the third paragraph most probably means ．
A．going straight up or down
B．flying high and fast
