　　23. It can be inferred that the author of the passage considers traditional scholarly methods courses to be aspects of the conventional course, the usual procedure of assigning a large number of small problems drawn from the entire range of historical periods was abandoned, though this procedure has the obvious advantage of at least superficially familiarizing students with a wide range of reference sources.此题考的理解较深，原文中的这句话是说传统方法教程中的人工痕迹明显，为了达到教学目的，布置了太多的范围广泛的小问题，与真正的研究并不符。)

　　 irrelevant to the work of most students

　　 inconsequential because of their narrow focus

　　 unconcerned about the accuracy of reference sources

　　 too wide-ranging to approximate genuine scholarly activity

　　Experiments show that insects can function as pollinators of cycads , rare, palmlike tropical plants. Furthermore, cycads removed from their native habitatsand therefore from insects native to those habitatsare usually infertile. Nevertheless, anecdotal reports of wind pollination in cycads cannot be ignored. The structure of cycads male cones is quite consistent with the wind dispersal of pollen, clouds of which are released from some of the larger cones. The male cone of Cycas circinalis, for example, sheds almost 100 cubic centimeters of pollen, most of which is probably dispersed by wind. Still, many male cycad cones 球果) are comparatively small and thus produce far less pollen. Furthermore, the structure of most female cycad cones seems inconsistent with direct pollination by wind. Only in the Cycas genus are the females ovules accessible to airborne pollen, since only in this genus are the ovules surrounded by a loose aggregation of megasporophylls rather than by a tight cone.
