Scope , complexity ,and scale of even a single 5G netwoork are massively largherthan in today's networks .The main challenge is automation on all levels of the 5G eco system.without it , the network simply will not work; nei ther for the anticipated scale nor for the desired functional complexity .

Fundamentally , automation is realized bya largely self-governed network bound to varying business goals : ifs configuration , its services , how they are provided , and how it is managed . A governance model , ideally realized by policies , defines how these goals are implenented andmoni tored . Those policies can be low-level confi gurati on parameters , mid -level strategies or high-level intents and goals . Using a mix of these -policies implies translation between : top-down for realization and bottom-up for action / benefit and validation purposes .

Networks and models must address multiple , diverse constituencies . Human intervention should be kept to a minimum (oversight ) . Managenment means monitoring and repair ; not control . Classic self capabilities are the benefits

【英译中】The shape of the world is changing almost as dramatically as this city's skyline. Today the cold war is over. The risk of the global nuclear conflict has been greatly reduced and the free flow of goods and ideas is bringing to life the concept of a global village. But just as all nations can benefit from the promise of this new world, no nation is immune to its perils. We all have a stake in building peace and prosperity, and in confronting threats that respects no borders-terrorism and drug trafficking, disease and environmental destruction. To meet these challenges most effectively, China and the United States must act in concert. Some argue that with the Cold War's end, the strategic importance of the US-China relationship has diminished. I believe they have it exactly backwards. As a new century begins, the importance of strengthening the ties between the United States and China will grow even greater.

Your Bean Steak （素肉排), Sir!What sort of food are we likely to be eating in the year
Your Bean Steak (素肉排), Sir!
What sort of food are we likely to be eating in the year 2000？
Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.
For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed (分配 ).
This does not mean, however, that our diet (饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.
By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.
1.Most people believe that food supplies in the future().
A、will become a very serious problem
B、will be the same as they are today
C、will be enough in quantity but not good in quality
D、will be much better than they are today
2.The reason why people are hungry in today's world is().
A、poor farming methods and bad distribution
B、slow growth of food production
C、food shortages all across the world
D、fast rising population
3.The word "bacon" in Line 5, Para.3 most probably is().
A、a kind of "meat" made from grain
B、meat made from fish
C、food for fish
D、meat made from pigs
4.The word "particular" in Line 4, Para.4 means().
A、special
B、choosy
C、detailed
D、very exact
5.The title of this passage suggests that().
A、food in the future will be tasteless
B、there will be worldwide food shortages
C、diet in the future will be very different
D、science is making rapid progress

About a century ago more people would not have appreciated the study of a foreign language as they do today. Gone are those days when patriotism towards one's own language was a major obstacle to learning foreign languages, a time when most nations were trying to throw their alien rulers out of their countries in their freedom struggles. Gone are those days when people were proud of their mother or father tongues and considered that their languages alone will suffice the need to survive. Language skills today have become as important as other business and career skills like IT, vocational or professional skills. Thus learning a foreign language today has become essential for an individual whether it is for careers, growing a business, or even to make an impression.
All that one needs to possess these days is a drive to learn a foreign language and there are all kinds of institutes and courses that teach various foreign languages like French, German, Spanish, and Japanese. Today's world economy has bridged the barriers of race, sex, color and religion and the world has become a smaller place. Today's businesses also demand language skills to expand and grow in other countries. Tens and hundreds of businesses world wide are expanding and growing their businesses by promoting them in countries other than their countries of origin. The tremendous growth of the Internet has further increased the demand for language skills. In Canada an official rule also says that all commercial establishments must have their websites created both in English and French, the official languages of the country.
Language can also ease race and border barriers. You are more welcome in an alien nation if you know the language of the people there and can converse in their tongue. People in these countries immediately respect you and think you care about their culture as much as they do because in any culture language is the key identity.
One of the reasons for not studying a foreign language in the past is______.
A．it was too difficult
B．it was not allowed
C．it was taught by foreign rulers
D．it was seen as disloyalty

Twenty years ago, computers were【B3】______, but they were very large and extremely expensive. Few, if any,【B4】______purchased computers for home use. Over the years, the price of the "guts" Of a computer its memory—has declined to less than a thousandth of the price per unit of memory that prevailed twenty years ago. This is the main reason why computers cost so much less today than they used to. Moreover,【B5】______improvements have made it possible to【B6】______memory circuitry that is small enough to fit into the portable personal computers that many of us own and use.【B7】______, as the price of computation has declined the average consumer and business have spent more on purchasing computers. 【B8】______, improved agricultural technology, hybrid(杂交)seeds,【B9】______animal breeding, and so on have vastly increased the amount of output a typical farmer can produce. The prices of goods such as meats and grains have fallen sharply relative to the prices of most other goods and services. As agricultural prices have fallen, many households have decreased their total expenses on food. Even though the【B10】______of a product purchased generally increases when its price falls, total expenses on it may decline.

The brain drain （人才流失) is a universal phenomenon, and countries that don't face up to
The brain drain (人才流失) is a universal phenomenon, and countries that don't face up to the new reality will be losing some of their most precious resources. The northeast of England is its poorest region, and has experienced a severe loss of highly qualified professionals-to-be. Some of the most able 18-year-olds are going to other parts of Britain, even to other countries. What is happening here is happening to Britain as a whole. Most noticeably, there is a growing trend of British students' taking degrees in American universities. This year the number will break the psychological barrier of 1 000 students for the first time.
And what is happening at the secondary-school level is happening to higher education. Wherever they come from, today's students have a very different perspective on education from their parents. Because of television, the Internet and their own travels, these students see the world as a much smaller place than their parents once did. They are more confident in accepting the challenge of moving from one country to another, from one culture to another; in many eases they can even apply to schools over the Internet. Students are also more aware of the overall cost of education and are looking for value for money. Plus, for many, education linked to travel is a better option than education at home.
In the context of student globe-trotters (周游世界者), as world-class British universities like Oxford suddenly find themselves fighting over British students with the Harvards of the world, they face major challenges. It is not simply that Harvard is a wealthier institution: Harvard University's endowment— $14.5 billion—is estimated to be ten times that of Oxford. Harvard also offers a radically different educational experience, stressing breadth of study and real-world applications of knowledge.
Today, bound in by nearly a millennium of tradition and lacking sufficient financial help from the national government, Oxford cannot easily respond to the quickened global pace of educational change. Rightly or wrongly, Oxford in particular has been slow—or unwilling—to put the kind of emphasis other universities have on more business-friendly curricula (课程). Thus it has slipped behind universities like Cambridge and Harvard in the battle for resources that tend to go to more business-minded institutions.
Education is an expensive business, but the consequences of a failure to educate—especially in an increasingly globalized world—are even more expensive.
From the first paragraph, we know that ______ .
A．many countries are experiencing the brain drain, Britain is one of them
B．most British students prefer to take degrees in American universities than in British ones
C．Britain is suffering a more serious loss of professionals-to-be than other countries
D．the brain drain is only happening in the northeast poor regions of England

With human footprints on the moon, radio telescopes listening for messages from alien creatures (who may or may not exist), technicians looking for celestial and planetary sources of energy to support our civilization, orbiting telescopes' data hinting at planetary systems around other stars, and political groups trying to figure out how to save humanity from nuclear warfare that would damage life and eliminate on a planet-wide scale, an astronomy book published today enters a world different from the one that greeted books a generation ago. Astronomy has broadened to involve our basic circumstances and our mysterious future in the universe. With eclipses and space missions broadcast live, and with NASA, Europe, and the USSR planning and building permanent space stations, astronomy offers adventure for all people, an outward exploratory thrust that may one day be seen as an alternative to mindless consumerism, ideological bickering, and wars to control dwindling resources on a closed, finite Earth.
Today's astronomy students not only seek an up-to-date summary of astronomical facts: they ask, as people have asked for ages, about our basic relations to the rest of the universe. They may study astronomy partly to seek points of contact between science and other human endeavors: philosophy, history, politics, environmental action, even the arts and religion.
Science fiction writers and special effect artists on recent films help today's students realize that unseen worlds of space are real places—not abstract concepts. Today's students are citizens of a more real, more vast cosmos than conceptualized by students of a decade ago.
In designing this edition, the Wadsworh editors and I have tried to respond to these developments. Rather than jumping at the start into murky waters of cosmology, I have begun with the viewpoint of ancient people on Earth and worked outward across the universe. This method of organization automatically (if loosely) reflects the order of humanity's discoveries about astronomy and provides a unifying theme of increasing distance and scale.
This passage is most probably taken from
A．an article of popular science.
B．the introduction of a book of astronomy.
C．a lecture given by the author to astronomy students.
D．the preface of a piece of science fiction.
