In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive. Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees. We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this. We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food. What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if all of us think about the problem, we will have a better and cleaner planet in the future. From the passage we can see that the world's natural resources _ . A) will never be used up B) are being polluted C) are as plentiful as in the past D) are being used up very quickly

Q: When asked what they want for a gift, most teens would say a CD player, or maybe an iPod, but I want Lego. I received my first set for my fifth birthday, a tiny pizzeria with an umbrella and a delivery truck. Since then my collection has expanded rapidly and I have built skyscrapers, constructed spaceships and designed submarines. There is a small area in my house designated as The Lego Room. Beyond its door, I fantasize and govern my own small world of castles, modem cities, and thousands of Lego people. Each time I enter The Lego Room, a new story is created. Once, a friend asked to tour this room. Amazed by my Star Wars models, he reached for a ship and accidentally knocked over a restaurant, breaking it to pieces! This disaster became an opportunity to rebuild and I fashioned a two-story food court with a McDonald's, pizzeria, and drive-thru. It was better than the original! Ideas for new constructions fill my head and I write them down in a sketchbook. Lego represents a creative consistency in my life, much as an artist has his canvas and a musician, his violin. Lego has taught me to be an architect, engineer, governor, economist and so on. Lego has provided the building blocks of my future, developing my math skills and ability to follow complex directions. As I build new worlds, brick by brick, I imagine my own possibilities and opportunities. Through the "lives" of my Lego friends, I have been able to act out all kinds of experiences. They have served as a link between my childhood and manhood. My friends say I'm childlike and there is truth to that, but perhaps we should all find a way to keep in touch with our childhood. Lego is mine. What did the author receive for his fifth birthday? A) Some CDs. B) An iPod. C) A kind of toy. D) A book
A: C
(Question)
In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, the era of digital convergence goes better than yesterday's celebrated "information superhighway." Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each other. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media. The problems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable. Even once global standards are assured, however, a further obstacle lies in wait. The Internet is plagued by long, erratic (,) response times because it is a pull-technology, driven by patterns of user demands. Push-technology, on the other hand, reverses the relationship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom . Besides the issue of consumer habits, infrastructurecosts are set to be immense, and will have to be met by national states or the private sector before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coercedthrough clever marketing to upgrade to newer phones with more... What is pull technology? A) It is the Internet system affected by long, uncertain response times. B) It is the way of business operation driven by user demands. C) It is the technology to send information to passive users. D) It is a way to blend one-way television with interactive Internet.
