In an educational context, the term ‘learner independence’ has gained increasing importance in recent years. It is of particular (26)_________ to language learning and commonly refers to the way students confidently control and organise their own language learning process. While some people seem to have an almost instinctive flaw for languages, (27) _________ have to rely on strategies to maximise their skills and learn a foreign language more effectively. The main thing to remember is that becoming a truly independent learner ultimately depends above all on taking responsibility for your own learning and being prepared to take every opportunity available to you to learn. You also increase your chances of (28)_________ by learning according to your own needs and interests, using all available resources. Research shows that learners (29)_________ adopt this approach will undoubtedly manage to broaden their language abilities considerably and, (30)_________ are more likely to achieve their objectives in the longer term.

Fiberscopes are one of the most important outcomes of the science of fiber optics. Fibers made of glass and transparent acrylic plastic are capable of conveying light energy, and when thousands of these fibers are combined in what is called a fiberscope, they can transmit images. The most common fiberscopes contain about 750,000 fibers, each 0.001 centimeter, or 10 microns, in diameter. For certain uses, the diameter of the fiber may be as small as 5 microns. Fiberscopes have a wide range of applications. In the medical field, physicians use fiberscopes to examine internal organs and as an aid in delicate surgeries. Miniature probes have also been developed to view muscle fiber, skin tissue, and blood cells. Fiberscopes have also found varied uses in industry, particularly to inspect or control operations in inaccessible areas. Bundles of fiberscopes fused together in a solid plate, called a faceplate, are being used in the manufacture of television picture tubes and other cathode-ray tube devices. The most far-reaching applications of fiber-optic technology are in communications. Optical fibers carry voice messages for telephone service. The sound of the voice is electronically broken down into thousands of pulses per second, which causes a transmitting laser to send coordinated pulses of light through the optical fibers. At the receiving end, the light pulses are converted to electrical signals and the voice message is reconstructed. Light-wave communication systems can handle an immensely greater number of telephone calls and television programs than the current system, and they will form the basis of the "electronic superhighway" expected to crisscross the nation in the near future of the information age.

Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership. "Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources," he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism." Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world's 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve, and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newspaper, Boley and co-author Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state. Ecotourists not only provide a boost to the economy in such places, but they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection. “The public has become increasingly less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public's interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban, and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages, and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas.
