Traditional surgical procedures require surgeons to make large incisions(伤口) in a patient’s body in order to gain access to the internal organs. It was once common for heart surgeons, who perform highly specialized and complex procedures, to make long incisions in a patient’s chest and then split the breastbone to reach the heart. Patients who undergo surgery are often at the risk of infection, as bacteria can infect the cut in the skin. In addition, there is often a lengthy recovery period.
A surgical technique known as “keyhole surgery” has become more common in recent years. In general, the surgeon will make a couple of small incisions around the area where the operation is going to be performed. Tubes are pushed into the holes, and a tiny camera, which is called an endoscope, is put into the body. The camera is attached to a large monitor screen that is positioned so that the doctor can see it while he performs the operation. In addition to the camera, doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push it to the right.
Other advancements in technology are also being used today in the OR (operation room). A new machine called the “da Vinci Surgical System” has been tested in hospitals in the U.S.. Unlike keyhole surgery, the da Vinci’s robot’s moving parts are designed to imitate the natural hand and wrist movement of a surgeon, thus providing better control and sensitivity. The system is controlled by a surgeon from a console(控制台). Sitting at a console a few feet from the patient, the surgeon can perform an operation by holding and moving highly sensitive pads that enable him or her to control the instruments. The area of the body on which the surgeon is working is enlarged on a screen, which is attached to the console. This gives surgeons a realistic three-dimensional view of the area — similar to what they would see during a traditional surgical procedure.
Although the da Vinci Surgical System is undergoing some trials for some procedures, it has been welcomed as revolutionary by many surgeons. Patients with serious illnesses must still undergo major surgery, but the smaller incisions and less invasive procedures typically mean that a shorter recovery time is needed. In some cases, the patient’s stay in the hospital has been cut in half when the da Vinci Surgical System was used. On the downside, some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology. As surgeons become more familiar with the machines, the time needed for surgical procedures is likely to decrease.

A few years ago it was popular to speak of a generation gap, a disagreement between young people and their elders. Parents said that children did not show them proper respect and obedience (服从), while children complained (抱怨) that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually the generation gap has been around for a long time. Many people argue that a gap is built into the fabric (结构) of our society.
One important cause of the generation gap is the chance that young people have to choose their own ways of life. In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and agree to, and to continue the family occupation (职业). In our society, young people often travel great distances for their education, move out of the family home at an early age, marry or live with people whom their parents have never met, and choose occupations different from those of their parents.
In our easily changing society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do. Often, however, the strong desire that parents have for their children are another cause of the disagreement between them. Often, they discover that they have very little in common with each other.
Finally, the speed at which changes take place in our society is another cause of the gap b
etween the generations. In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date overnight. The young and the old seem to live in two very different worlds, separated by different skills and abilities.
No
doubt, the generation gap will continue to be a feature (特点) of American life for some time to come. Its causes are rooted in the freedom and changes of our society, and in the rapid speed at which society changes.
69. The main idea of the first paragraph is that ____________.
A. the generation gap suddenly appeared
B. the generation gap is a feature of modern social life
C. people can reduce the generation gap
D. many critics argue over the nature of the generation gap
70. The word “around” in Paragraph 1 means ____________.
A. on all sides B. near C. in every direction D. in existence
71. In American society, young people often ____________.
A. depend on their parents to make a life
B. stay with their parents in order to get a chance for higher education
C. seek the best advice from their parents
D. have very little in common with their parents
72. Which of the following statements is true according to the passage?
A. Parents should be strict with their children.
B. The younger generation should value the older generation for their wisdom.
C. The generation gap is partly caused by the older generation.
D. The generation gap does not exist in American society.
I HEAR America beeping(嘟嘟响).
Beep,says my cellophane when it gets a text message.
Beep,says my microwave oven when my sandwich is warmed up.
Sometimes I long for a natural sound:a bird singing,dog barking,children laughing, anything to drown out the maddening beeps that have become the soundtrack(配乐)to modern life.
My cellophane? It isn’t enough that its ring tone offerings seem to stretch from “annoymg” toextremely “annoying”. It also has to beep whenever someone texts messages me.
The microwave? A bell rings when it's finished heating my food.But is that enough? No.If I don’t rush to it right away, it starts beeping,like an impatient child tugging(用力拉) at my sleeve(袖子).
The smoke detector(探测器) is the worst offender.When its batteries are in need of replacement,it 1ets out a series of chirps.The things that don’t beep buzz(嗡嗡响).And for some reason,beeping and buzzing is beneath them,they clear their throats and perform a symphony. Like my TV, each time I turn it on, it performs an aria(咏叹调):La di da di dum.Salutions! Here I am! Same thing when I turn it off: La di da di dum.Good bye, kind sir! Until the next time
But at 1east I know where each of these sounds is coming from.That isn’t always the case.For weeks, my wife and I were awoken in the night by a beeping.There,in the stillness, we went through the possible suspects.Could we have a text message? Could it be any of the devices(装置)able to make a sound? Curling iron, rice cooker, smoke detector, TV set,clock radio...
The only way to tell was to chase the sound down ,but no sooner would we pull on our bathrobes than the beeping would stop. We didn’t hear it every night but often enough that we would climb into bed wondering whether our sleep would be interrupted by that maddening sound,that beep.
Finally,early one morning,my wife found it:in the study,under a desk,a big plastic cube that was plugged into the wall.It was an uninterruptible power supply that we’d inherited(继承)from my wife’s mother.We’d never known it was capable of speech.
I think it just wanted someone to talk to.
14.What does the writer truly mean by saying“I hear America beeping”?
A.American people like devices that beep.
B.Americans are crazy about sending text messages.
C.In modern society people are dependant on technology.
D.The soundtrack to modern life is no longer natural.
15.Why couldn’t the author and his wife find the source of the noise in their house in the beginning?
A.There were too many devices for them to check.
B.They were unwilling to get up at midnight.
C.They had never known that thing could beep too.
D.The noise didn’t come every day.
16.After reading this passage,we can probably tell the author .
A.enjoys being surrounded by beeps B.has a touch of humor in his writing
C.tries to avoid using anything that beeps
D.understands the beeping is designed to be user-friendly
