A French-language daily in Belgium has issued(出版) what is thought to be Europe’s first 3D newspaper. But you must read it with a pair of special glasses. All the photos and ads in La Derniere Heure’s (DH) special edition(版) were given a three-dimensional effect(3D效果), but the text remained the same. DH’s editor said there were no further 3D plans because of the costs. Reviewers in France spoke highly of the paper, but they said the overall result was “far from perfect”. Editor Hubert Leclercq said it took two months to get ready for the special edition, which had a higher than normal print run of 115,000 copies for the stores selling newspapers. “We hear about 3D cinema, television and video games, so we took up the challenge,” Mr. Leclercq told the AFP news agency. According to PC World’s French edition, readers could get the best results by holding the paper 50cm from the eyes in a well-lit area. “It takes a few minutes to get used to pictures in 3D,” it said, noting the limited quality of the viewing lenses(镜片). It’s said some of the images - especially the ads - had a good 3D effect, but that other pictures were not clear or difficult to look at.  小题1:The Europe’s first 3D newspaper was from . A. Belgium B.
