Entering Space, astronauts can give us a fascinating account of a shuttle flight, describing the pressure of a countdown and launch, the complexities of living the days in the strange weightless environment, the challenges of working in space, the emotional effect of seeing earth from space, the drama of the meteoric landing.
However, there are also plenty of things that astronauts can’t do because of their weightless environment, and that’s very sad. What’s more, they can’t even let their sadness show, because it’s impossible to cry in zero gravity.
Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears don’t flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go – they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. “Tears,” he said, “don’t fall off of your eye... They just kind of stay there.”
Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that’s not the case in space. The space environment dries out astronauts’ eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. “My right eye is painful like crazy.” Feustel told his teammate during the walk.
Since gravity doesn’t work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait – “When the tears get big enough they simply break free of the eye and float around,” astronaut Ron Parise told The Atlantic.
There are lots of small things – things like crying – that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can’t talk to each other directly. They also can’t eat or drink in normal ways. They can’t even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.
Thus, perhaps it’s only space explorers who can honestly say: “Gravity, you’re the best.”What can we conclude from the 2nd and 3rd paragraphs?
A.Astronauts are unable to feel sad in space. |
B.Tears produced in space don’t flow downward. |
C.Astronauts produce fewer tears in space. |
D.Tears produced in space flow down more slowly. |
What can the astronaut do to get rid of the tears?
A.Get the tears big enough to break away from his eyes. |
B.Get the tears big enough to fall off of his eyes. |
C.Rub his eyes against his helmet to let the tears float forward. |
D.Rub his eyes by hand to let the tears float around. |
What’s the second-to-last paragraph mainly about?
A.Suggestions on how astronauts can stay comfortable in space. |
B.Why burping is impossible in space. |
C.Things that humans can’t do without gravity. |
D.Other basic things that are difficult to do in space. |
What can be the best title of this passage?
A.In the sky, you can’t cry |
B.In the sky, you can’t burp |
C.No Gravity, no tears |
D.Better life with gravity |
Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient —no matter where he or she may be.
Online doctors offering advice based on normal symptoms(症状) are the most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex(复杂的) medical pictures around the world — CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’ opinions and diagnosis are common. The writer chiefly talks about _______.
A.the use of telemedicine | B.the on-lined doctors |
C.medical care and treatment | D.communication improvement |
The basis of remote diagnosis will be _______.
A.personal data assistance | B.some words of a patient |
C.real physiological information | D.medical pictures from the Internet |
Which of the following statements is true according to the text?
A.Patients don’t need doctors in hospitals any more. |
B.It is impossible to send a patient’s signs over the telephone. |
C.Many teams use telemedicine dealing with disasters now. |
D.Broadband communications will become cheaper in the future. |
The “problem” in the fourth paragraph refers to the fact that _______.
A.bandwidth isn’t big enough to send complex medical pictures |
B.the second-generation of Internet has not become popular yet |
C.communication satellites can only deal with short-term needs |
D.there is not enough equipment for spreading the medical care |
It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects (UFO). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report.
Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken? UFOs are _____.
A.flying high up in the sky | B.strange flying objects |
C.difficult to believe | D.very interested |
A UFO was seen one night _____.
A.when they were walking across a yard to Burdens’ room |
B.while they were looking at the light |
C.when Burdens noticed the moon appearing strange |
D.while they were having dinner |
The UFO moved _______.
A.regularly | B.in a changeable way | C.slowly | D.fast |
The UFO looked like _____ .
A.smoke | B.a large plate | C.light | D.a jumping object |
The UFO was seen ______ .
A.by Burdens and his friend | B.brighter in the darkness |
C.by several people | D.to have a yellow bottom and a red top in the same way |
The earliest controversies about the relationship between photography and art centered on whether photograph’s fidelity to appearances and dependence on a machine allowed it to be a fine art as distinct from merely a practical art. Throughout the nineteenth century, the defence of photography was identical with the struggle to establish it as a fine art. Against the charge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing, a revolt against commonplace vision, and no less worthy an art than painting.
Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves—anything but making works of art. They are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art. It shows the extent to which they simply take for granted the concept of art imposed by the triumph of Modernism: the better the art, the more subversive it is of the traditional aims of art.
Photographers’ disclaimers of any interest in making art tell us more about the harried status of the contemporary notion of art than about whether photography is or is not art. For example, those photographers who suppose that, by taking pictures, they are getting away from the pretensions of art as exemplified by painting remind us of those Abstract Expressionist painters who imagined they were getting away from the intellectual austerity of classical Modernist painting by concentrating on the physical act of painting. Much of photography’s prestige today derives from the convergence of its aims with those of recent art, particularly with the dismissal of abstract art implicit in the phenomenon of Pop painting during the 1960’s. Appreciating photographs is a relief to sensibilities tired of the mental exertions demanded by abstract art. Classical Modernist painting—that is, abstract art as developed in different ways by Picasso, Kandinsky, and Matisse—presupposes highly developed skills of looking and a familiarity with other paintings and the history of art. Photography, like Pop painting, reassures viewers that art is not hard; photography seems to be more about its subjects than about art.
Photography, however, has developed all the anxieties and self-consciousness of a classic Modernist art. Many professionals privately have begun to worry that the promotion of photography as an activity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity—in short, an art. What is the author mainly concerned with? The author is concerned with
[A]. defining the Modernist attitude toward art.

[B]. He wants to set forth an analogy between the Abstract Expressionist painters and classical Modernist painters.
[C]. He wants to provide a contrast to Pop artist and others.
[D]. He wants to provide an explanation of why serious photography, like other contemporary visual forms, is not and should not pretend to be an art. How did the nineteenth-century defenders of photography stress the photography?

When we say that Cambridge is a university town, we do not mean just that it is a town with a university in it. Manchester and Milan have universities, but we do not call them university towns. A university town is one where there is no clear separation between the university buildings and the rest of the city. The university is not just one part of the town; it is all over the town. The heart of Cambridge has its shops, pubs, market-place and so on, but most of it is university-colleges, faculties, libraries, clubs and other places for university staff and students. Students fill the shops, cafes, banks, and churches, making these as well part of the university.,
The town was there first. Two Roman roads crossed there, and there are signs of building before Roman times (earlier than A.D. 43). Cambridge became a center of learning, and the authority of the head of the university was recognized by the king in 1226.
With about 8,250 undergraduates and over2,000 postgraduates, the city is a busy place in “full term” .Undergraduates are not allowed to keep cars in Cambridge, so nearly all of them use bicycles. Don’t try to drive through Cambridge during the five minutes between lectures. Your bicycle must go through a boiling sea of other bicycles hurrying in all directions, if you are in Cambridge at five minutes to the hour any morning of full term, you know that you are in a university town.What is called a university town?
A.A town with a university in it
B.B. A university with a town in it.
C. One where there is no clear separation between a university and a town.
D.One where there are both a university and a town.How many students does Cambridge have?
A.Eight thousand, two hundred and fifty. | B.Two thousand. |
C.Ten thousand. | D.More than ten thousand. |
Which of the following is NOT mentioned in the passage?
A.the university is all over the town |
B.the town came earlier than the university |
C.during the five minutes between lectures, your bicycle must go through other bicycles hurrying in all directions. |
D.the teachers have many strange ways of making their lectures lively and interesting. |
What’s the title of the passage?
A.Cambridge—A University Town. | B.Cambridge – A Centre of Learning |
C.Cambridge with Many Students. | D.Cambridge with a Long History |
President Clinton’s decision on Apr.8 to send Chinese Premier Zhu Rongji packing without an agreement on China’s entry into the World Trade Organization seemed to be a massive miscalculation. The President took a drubbing from much of the press, which had breathlessly reported that a deal was in the bag. The Cabinet and Whit House still appeared divided, and business leaders were characterized as furious over the lost opportunity. Zhu charged that Clinton lacked “the courage” to reach an accord. And when Clinton later telephoned the angry Zhu to pledge a renewed effort at negotiations, the gesture was widely portrayed as a flip-flop.
In fact, Clinton made the right decision in holding out for a better WTO deal. A lot more horse trading is needed before a final agreement can be reached. And without the Administration’s goal of a “bullet-proof agreement” that business lobbyists can enthusiastically sell to a Republican Congress, the whole process will end up in partisan acrimony that could harm relations with China for years.
THE HARD PART. Many business lobbyists, while disappointed that the deal was not closed, agree that better terms can still be had. And Treasury Secretary Robert E. Rubin, National Economic Council Director Gene B. Sperling, Commerce Secretary William M. Daley, and top trade negotiator Charlene Barshefsky all advised Clinton that while the Chinese had made a remarkable number of concessions, “we’re not there yet,” according to senior officials.
Negotiating with Zhu over the remaining issues may be the easy part. Although Clinton can signal U.S. approval for China’s entry into the WTO himself, he needs Congress to grant Beijing permanent most-favored-nation status as part of a broad trade accord. And the temptation for meddling on Capital Hill may prove over-whelming. Zhu had barely landed before Senate Majority Leader Trent Lott (R-Miss) declared himself skeptical that China deserved entry into the WTO. And Senators Jesse A. Helms (R-N.C.) and Emest F. Hollings (D-S. C.) promised to introduce a bill requiring congressional approval of any deal.
The hidden message from these three textile-state Southerners: Get more protection for the U. S. clothing industry. Hoping to smooth the way, the Administration tried, but failed, to budge Zhu on textiles. Also left in the lurch: Wall Street, Hollywood, and Detroit. Zhu refused to open up much of the lucrative Chinese securities market and insisted on “cultural” restrictions on American movies and music. He also blocked efforts to allow U. S. auto makers to provide fleet financing.
BIG JOB. Already, business lobbyists are blanketing Capitol Hill to presale any eventual agreement, but what they’ve heard so far isn’t encouraging. Republicans, including Lott, say that “the time just isn’t right” for the deal. Translation: We’re determined to make it look as if Clinton has capitulated to the Chinese and is ignoring human, religious, and labor rights violations; the theft of nuclear-weapons technology; and the sale of missile parts to America’s enemies. Beijing’s fierce critics within the Democratic Party, such as Senator Paul D. Wellstone of Minnesota and House Minority leader Richard A. Gephardt of Missouri, won’t help, either.
Just how tough the lobbying job on Capitol Hill will be become clear on Apr. 20, when Rubin lectured 19chief executives on the need to discipline their Republican allies. With business and the White House still trading charges over who is responsible for the defeat of fast-track trade negotiating legislation in 1997, working together won’t be easy. And Republicans—with a wink—say that they’ll eventually embrace China’s entry into the WTO as a favor to Corporate America. Though not long before they torture Clinton. But Zhu is out on a limb, and if Congress overdoes the criticism, he may be forced by domestic critics to renege. Business must make this much dear to both its GOP allies and the Whit House: This historic deal is too important to risk losing to any more partisan squabbling
