Aseries of 15 one-day courses is being planned for small businesses in the Scar brook area during September and October. The focus will be on practical training in a range of business skills areas, including presentation skills, marketing on the internet, negotiating effectively and dealing with difficult clients. The courses are being run by a recently founded training organisation, Scar brook Training Company (STC). This organisation is a partnership between Scar brook Council and the town's Business Development Agency, which has been training Scar brook businesses for a number of years. A spokesperson for the company confirmed that STC, which receives government funding, is offering these courses free of charge. This is an excellent opportunity for local businesspeople, who would otherwise expect to pay as much as ￡250 to attend a one-day business skills course. Although firms are allowed to register a maximum of two employees per course, participants may attend as many courses as they wish. Bookings will take place for the two weeks following an open day at STC on 27 August. STC recommends that applications for places are submitted as soon as possible to avoid disappointment. For further information, contact STC on: 0859 211432 or online at: http://www, stc.co.uk. Courses are aimed at companies in and around Scar brook. A．Right B．Wrong C．Doesn't say

A library is more than just a place where books are stored. A library is a source of information. The information may come from books (fiction , nonfiction, or reference book), from periodicals (newspapers, magazines, and journals), from audio-visual materials (records, cassettes, microfilms, video tapes, etc.), or even from a computer terminal. Students go to libraries to study and write research papers. The periodicals room of a university library is where foreign students often find newspapers and magazines from their countries . In the reference room, they can find catalogs(目录) from many universities in the U.S. and other countries. If you are buying a used car, the reference librarian can show you the Blue Book which lists the prices of new and used cars. People who need information in a hurry can telephone the reference librarian at many libraries. There are as many different library services as there are types of people who use them. Children’s libraries provide materials for young readers. They sometimes have storytellers who read stories to groups of children , and a few have computers for the children to play with. Music lovers can listen to recordings of their favorite musicians in music libraries . Some libraries have painting and sculpture exhibits, and most libraries offer special services for blind people, such as books in Braille, ―talking‖ books , and Kurzweil Reading Machines. Libraries provide entertainment as well as information. Novels and short stories from a library’s fiction collection are a good source of enjoyable reading practice.
