To avoid deiays, material should not be sent by normal post．Material should be sent “carriage paid”，including any customs and delivery costs． BolognaFiere may not be held responsible for the non-arrival or late arrival of artwork．All published works must be accompanied by a declaration bearing the ISBN number，publisher’s name and address． REQUIREMENTS The illustrations (i.e. the size of the sheet) must not exceed (超过) the following dimensions： Fiction：32*42cm(or 42*32cm) Non-fiction：50*70cm(70*50cm) Illustrations in larger formats will not be considered，nor will they be returned by BolognaFiere．The illustrations must be on paper or flexible board，maximum thickness 2mm(for scanner separation purposes). SELECTIONPROCESS All artwork received by the stated deadtine and meeting the specified requirements will be examined and selected by an international group(whose decision is final)，inclnding five members(from publishing houses and art schools) appointed each year by BolognaFiere. ANNUAL Each illustrator selected by the Committee will be granted two pages in the Annual，for the reproduction of all or some of the illustrations as well as a space for the bibliography(参考书目). BotognaFiere has the fight to choose the works to be published in the Annual and to make complete or partial reproductions． EXHIBITIONS ABROAD After the Bologna event，the illustrator Exhibition will travel to Japan under the supervision of JBBY．The illustrator exhibition may afterwards be transferred to other venues(场馆)in other countries，The Exhibitions of illustrations held abroad follow the same rules and regulations as the illustrator Exhibition，and the provision(条款)of the regulations are extended to tile organizers of the exhibitions held abroad． RETURN OF ARTWORK All the works will be returned to their owners by BolognaFiere by the end of July 2012．小题1:According to the text，the Illustrators Exhibitions A．will last five days in all in July every other year B．is intended for college students who are good at painting C．is held by the Bologna Children"s Book Fair D．can strengthen the relationship between illustrators and publishers 小题2:The illustrators of the Illustrators Exhibitions A．should be at least 16 and no more than 25 B．may re-enter their artwork after it is returned C．should state the category of their artwork clearly D．may choose to attach a photo to the application form 小题3:Which of the following is unacceptable for delivering entries?
