单选题In computing, passwords are commonly used to limit access to official users. Yet the widespread use of passwords has serious drawbacks. Office workers now have to remember an average of twelve system passwords. In theory they should use different passwords for each site, but in reality these would be impossible to remember, so many people use the same password for all. An additional problem is that the majority use simple words such as "hello", or names of family members, instead of more secure combinations of numbers and letters, such as 6ANV76Y. This permits computer hackers to download dictionaries and quickly find the word that allows them access. When system users forget their passwords there is extra expense in supplying new ones, while if people are forced to change passwords frequently they often write them down, making systems even less secure. Therefore, it is clear that the idea of passwords, which have been used as security devices for thousands of years, may need rethinking. One possible alternative has been developed by the American firm Real User, and is called "passfaces". In order to access the system, a worker has to select a series of photographs of faces from a randomly (随机地) generated sequence. If the pictures are selected in the correct order, access is granted. This concept depends on the human ability to recognize and remember a huge number of different faces, and the advantage is that such a sequence cannot be told to anyone or written down, so is more secure. It is claimed that the picture sequence, which used photographs of university students, is easier to remember than passwords, and it has now been adopted for the United States Senate.

单选题Traffic is a perennial problem in Hongkong. Over the years many suggestions have been (1) to ease transport difficulties. These include from constructing wider roads and an underground railway (2) to staggering hours for schools to open and close. One official report pressed (3) for working hours to be spaced out to (4) congestion at (5) periods. In England and other countries this system is called staggering working hours because many business centers use it. It is (6) that greater working (7) can be achieved, employees are happier because they can arrange (8) personal working hours, buses and trains can be dispatched at suitable (9) , and so on. The idea of (10) working days follows on from staggering hours.

单选题The key position and role of women in the process of development is increasingly being recognized. Although the three great World Conferences of Women were more concerned with recognizing and compiling approaches to emancipation we can currently confirm a general sharpening of awareness. It has become clear that the Third World cultures, in earlier times strongly matriarchal, have been weakened in this respect by the methods of colonial education which are almost exclusively directed towards the male. Of the many criticisms of this situation let one voice be heard: "Development education' groups and programs are very much male dominated and lack woman's perspective". So, too, the hopes placed in vocational training--"vocationalization'--as an aid to equality have been disappointed since this in its turn was to large extent focused on the male. In these circumstances we should not be surprised that until now women have participated least in the educational processes which have been introduced. Only 20% attend primary school and the percentage of those who leave early is highest among girls. Because of the lack of basic training only around 10% take part in Adult Education programs. Hence it is vitally important to secure a turning point by increasing the awareness of the need for education. The International Conference at Jomtien in 1990 provided the solution to this: "A more educated mother raises a healthier family. She has fewer and better educated children. She is more productive at home and in the workplace and is better able to get further education." Many problems in school are consequences of incorrect or improperly balanced nutrition combined with .inadequate hygiene. Together these factors can lead to failure to keep pace in school. Hence even primary education for girls should be directed towards the basic needs and necessities and provide answers which are as simple as possible. In rural districts such answers will be different from those given in urban areas. The education of girls and women must to a large degree be an education for the life they will lead, tailored to a woman's position. In saying this we are in fact demanding that the education of women, like all educational work in the Third World, should be an integrated part of the community. Consequently there are many partners in this process school, family, small businesses, governmental and non-governmental organizations. The educational skill consists in keeping this interplay active in such a way that there is no deficiency in material content. An important consequence of this is the awakening of the desire to question, which, on the one hand presses for further education and on the other hand for its practical application.

单选题As our van pulled up to the ranch (牧场) to start a three-month program for troubled boys, we passed a cowboy on his horse. Bill was the owner of the ranch. We made eye contact through the dusty window and he winked (挤眼睛) at me and touched the brim of his cowboy hat in welcome. All summer long Bill and his ranch-hands taught us to ride horses, chop wood, and round up cattle. We started to understand the value of working with our hands. Knowing how important it was for boys like me to know that someone believed in them, he trusted us to do the job and do it right. We never let him down. The last day at the ranch, Bill pulled me aside and praised me for the work I had done—not only on the ranch, but also on myself. He told me if I ever needed anything I could count on him. Four years later, I took him up on that offer. I called him up and asked for a job. I told him how his confidence in me had given me the courage to change my life. He offered me a job on the spot. I"m proud to say that each summer I"m the one in the ranch to open the gate for a van full of young men who need someone to believe in them, so they can learn to believe in themselves.

单选题Concrete is probably used more widely than any other substance except water, yet it remains largely unappreciated. “Some people view the 20th century as the atomic age, the space age, the computer age — but an argument can be made that it was the concrete age,” says cement specialist Hendrik Van Oss. “It’s a miracle material.” Indeed, more than a ton of concrete is produced each year for every man, woman and child on Earth. Yet concrete is generally ignored outside the engineering world, a victim of its own ubiquity and the industry’s conservative pace of development. Now, thanks to environmental pressures and entrepreneurial innovation, a new generation of concretes is emerging. This high-tech assortment of concrete confections promises to be stronger, lighter, and more environmentally friendly than ever before. Concrete is also a climate-change villain. It is made by mixing water with an aggregate, such as sand or gravel, and cement. Cement is usually made by heating limestone and clay to over 2,500 degrees F. The resulting chemical reaction, along with fuel burned to heat the kiln, produces between 7% and 10% of global carbon-dioxide emissions. “When we have to repeatedly regenerate these materials because they’re not durable, we release more emissions,” says Victor Li who has created a concrete suffused by synthetic fibers that make it stronger, more durable, and able to bend like a metal. Li’s creation does not require reinforcement, a property shared by other concretes that use chemical additives. Using less water makes concrete stronger, but until the development of plasticizers, it also made concrete sticky, dry, and hard to handle, says Christian Meyer, a civil engineering professor at Columbia University. Making stronger concretes, says Li, allows less to be used, reducing waste and giving architects more freedom. “You can have such futuristic designs if you don’t have to put rebar in there, or structural beams,” says Van Oss. A more directly “green” c6nerete has been developed by the Australian company TecEeo. They add magnesium to their cement, forming a porous concrete that actually scrubs carbon dioxide from the air. While experts agree that these new concrete will someday be widely used, the timetable is uncertain. Concrete companies are responsive to environmental concerns and are always looking to stretch the utility of their product, but the construction industry is slow to change. “When you start monkeying around with materials, the governing bodies, the building departments, are very cautious before they let you use an unproven material,” Meyer says. In the next few decades, says Van Oss, building codes will change, opening the way for innovative materials. But while new concretes may be stronger and more durable, they are also more expensive — and whether the tendency of developers and the public to focus on short-term rather than long-term costs will also change is another matter.
