COLUMBUS, Ohio—The heart operation taking place in the pale-green operating room at the Ohio State University Medical Center was unusual. The patient, a 62-year-old man, was made to sleep, tied with blue drapes(消毒帷帘)and lying face up on a narrow table. But no one was touching him.

Instead, the operation was being performed by a robot, whose three metal arms went through pencil-sized holes in the man’s chest. At the ends of the robot’s arms were tiny metal fingers, with turning wrists, which held a tiny instrument, a light and a camera. The robot’s arms and fingers were controlled by Dr. Randall K. Wolf, sitting at a computer in a corner of the operating room about 20 feet away.

This sort of operation, heart surgeons say, is the start of what may be the biggest change in their profession since heart bypass surgery(心脏搭桥手术)began nearly 30 years ago. “The reason we make cuts is that we have big hands,” said Dr. Wolf, the director of the surgery at Ohio State. The robot’s dainty fingers, no longer than a nail on the small finger, at the end of the long sticks could work better.

Eventually, surgeons believe, most heart surgery will be done by robots whose arms are put in through pencil-sized holes punched in patients’ chests. Instead of directly staring into a patient’s body, surgeons will view magnified images of the operation on computer screens. In theory, the doctor would not have to be in the same room, or even the same country, as the patient.

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americans from being discovered by the people of Europe.

Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to “the edge of the world.” Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.

The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000km) wide where Columbus crossed it. Even at its narrowest it is about 2,000 miles (3,200km) wide.

Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world’s saltiest ocean.

There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than two miles (3.2km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This “deep” measures 30,246 feet-almost six miles (9.6km).

One of the longest mountain ranges of the world rises from the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands.

Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels(船) the crew were afraid they would be becalmed(停滞不前) here. Sometimes they were.

Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.

We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!

Which world is the Old World?

A. Africa               B. Europe                     C. Asia                  D. All of above

What caused people to be unwilling to explore the Atlantic?

A. There are no ships big enough to get across the Ocean.

B. Sailors were afraid of being lost in the Ocean.

C. The Atlantic Ocean was very unusual because it has few islands and the saltiest water.

D. Many incorrect ideas such as “the edge of the world”, “the equator with boiling hot water”, made people think the Ocean was full of danger.

What is the topic of the fifth paragraph?

A. How deep the water is

B. How to measure the water in the Atlantic Ocean

C. How much water the Ocean holds.

D. How rain affects the Ocean water.

We can learn from the text that ______.

A. the Atlantic is the largest ocean on earth

B. one of the longest mountain ranges lies in the Atlantic

C. the Atlantic has a lot of islands in it

D. sailing on the Atlantic Ocean is always quiet, smooth and safe

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americans from being discovered by the people of Europe.

It is more than 4,000 miles (6,400 km) wide where Columbus crossed it. Even at its narrowest it is about 2,000 miles (3,200 km) wide.   1.   .

One of the longest mountain ranges of the world rises from the floor of the Atlantic.   3.  . The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.

Ocean currents are sometimes called “rivers in the sea”. One of these “rivers” in the Atlantic is called the Gulf Stream. It is a current(流) of warm water. Another is the Labrador Current --- cold water coming down from the Arctic.  4.  .

Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the far north across the paths of ships.

Scientific Progress

Most scientific progress is the result of careful consideration of work that has already been done. The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life’s road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough.

When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end.

Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don’t know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance.
