America’s greatest technological achievement, the Hoover Dam, now has a companion piece, a bridge held up by the longest arch in the Western Hemisphere(半球). The Mike O’Callaghan-Pat Tillman Memorial Bridge, which opened this month and connects the U.S. states of Arizona and Nevada, crosses the vast chasm(峡谷)890 feet above the Colorado River that is controlled by the dam.
The striking 1,900-foot-long structure will improve traffic in the region and help protect the dam from being destroyed. It is the seventh highest bridge in the world, behind four in China, one in Papua New Guinea and one in the US state of Colorado.
“The Hoover Dam is the greatest civil engineering achievement in America’s history,” said the bridge project manager Dave Zanatell. “Our goal was not to outdo or outshine it. Our goal was to, in a respectful way, do something that would be great for our generation and that would stand besides Hoover Dam in a respectful and quality way that would become a part of Hoover’s legacy(遗产).”
Just as the Hoover Dam was built in the heart of the Great Depression(大萧条)and was seen as an example of the nation’s can-do spirit, some hope this project can also provide some uplift.
The bridge is surprising: at 1,050 feet, its support arch holds up a roadway that lies on 300-foot-long concrete pillars(柱子), some of the tallest in the world. It contains 16 million pounds of steel.
The idea of the bridge came into being in the 1960s because the top of the Hoover Dam has been a narrow two-lane road that is the fastest route from Arizona to Las Vegas and then the Pacific Northwest and Canada.
Access to the dam from each direction is a dangerously winding route, but massive trucks and passenger vehicles shared it for decades. During the day, when thousands of tourists travel to the dam from Las Vegas three times as many accidents as on a normal road will happen.
The bridge has a sidewalk on the side facing the dam. The wall on both sides is 54 inches high, so walkers can take photos there.

It's really true what people say about English politeness: it's everywhere.When squeezing past someone in a narrow aisle, people say "sorry".When getting off a bus, English passengers say "thank you" rather than the driver.In Germany, people would never dream of doing these things.
After all, squeezing past others sometimes can't be avoided.and the bus driver is merely doing his job.I used lo think the same way, without questioning it, until I started traveling to the British Isles and came to appreciate some more polite ways of communicating with people.
People thank each other everywhere in England, all the time.When people buy something in a shop, customer and retail assistant in most cases thank each other twice or more.In Germany, it would be exceptional to hear more than one thank you in such a conversation.British students thank their lecturers when leaving the room.English employers thank their employees for doing their jobs as opposed to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize others.Even when I was working and mistakes were pointed out to me.my employers stressed several times but none of their explanations were intended as criticism.It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable.This also is shown in other ways.British men still open doors for women, and British men are more likely to treat women to a meal than German men.However, 1 do need to point out here that this applies to English men a bit more than it would to Scottish men' Yes, the latter are a bit tightfisted.
【小题1】What is the author's attitude towards English politeness?
A.He appreciates it | B.He gives no personal opinion |

A.It's always a retail assistant who says thank you. |
B.A customer never says thank you to a retail assistant. |
C.They always say thank you to each other. |
D.They may say thank you only once. |
A.are more likely to be involved in a fighting. |
B.are not so willing to spend money for women. |
C.are more polite than English men. |
D.treat women in a polite way. |

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.
