In 1954 a turning point in medical history, resulting from applied bionics, was the first" open heart" surgery done in Minneapolis, Minnesota, by Dr. W. Lillehei’’s techniques for the first time allowed the patient to be operated on while blood was supplied to the patient from a donor. Today "open heart" surgery ,using more complicated methods and bionic devices, is common in the United States. Important technological advances such as those already mentioned have encouraged scientists to develop the artificial heart. Early in 1983,in its first use by a human patient, a medical team at the University of Utah Medical Center replaced the diseased heart by a Jarvik-7. The world watched amazed as television pictures of Dr. Clark showed him as he improved steadily after the surgery. His continued life demonstrated that a bionic device could imitate the action and function of a healthy heart. Dr. Clark lived for 112 days. Life-like or bionic machines have existed for several centuries. The development of tools by man’’ s ancestors is a good example of the application of bionics to extend human capabilities. Modern bionic research is especially involved in prosthetics devices that substitute for, or replace lost or diseased body parts such as arms ,legs ,and eyes. Recent advances in electronics have enabled scientists to make better use of electrical impulses in the control of prosthetic devices. One interesting research project is the development of an artificial eye in which video signals are transformed into light patterns that are sent into nerve receptors in the patient. The future for applied bionics seems to be promising. Existing bionic devices will become smaller, faster, and more effective. The artificial heart used for Dr. Clark is only one of experimental replacement devices. It is likely to be joined in the future by replacements for other internal systems or organs. Bionic livers, stomachs, and lungs are not impossibilities! The author’’ s attitude towards applied bionics is _____________.
A.
critical
B.
approving
C.
objective
D.
questioning

【单选题】What was the author always dreaming of when he was a little boy(). A. living on the farm forever. B. Leaving home for the city. C. Moving to the rural area. D. Dropping out of the school.
A.
When I was a little boy, I often dreamed of leaving home and escaping to a big city. We lived on a farm, and we always felt that we were quite cut off from the outside world, especially in the winter. As soon as I graduated from school, I packed my bags and moved to Shanghai-known as a sophisticated metropolis. However, I soon found that life in the city had its own problems too.
B.
There are several disadvantages in the city, First and foremost, it usually costs too much, especially with the soaring price like food and housing. Another disadvantage is pollution. As I suffered from asthma (哮喘) when I was young, I am afraid of awful weather or polluted air, which makes it impossible for me to go outing. Travelling is also one of the problems. Although I have a car, I seldom used it because of the bumper-to-bumper traffic.
C.
As is known to all, every coin has two sides. It holds true for city life. First, we can do a lot of interesting things here. You can enjoy all kinds of creativity or entertainment. Besides, people in the city are more easily provided with good jobs and have more opportunities to get advanced. Finally, if you like shopping, there are a variety of goods for you to choose from, What’s more, shops can be seen everywhere and are often within walking distance.
D.
Is life better in the city than that of countryside or rural areas Perhaps it is, when you are young. However, as you gradually get older, and especially when you have children, the tranquility of the countryside may seem more attractive to you. I really hope I can move back where I grew up soon.
