[单项选择]It is possible for students to obtain advanced degree in English while knowing little or nothing about traditional scholarly methods. The consequences of this neglect of traditional scholarship are particularly unfortunate for the study of women writers. If the canon--the list of authors whose works are most widely taught--is ever to include more women, scholars must be well trained in historical scholarship and textual editing. Scholars who do not know how to read early manuscripts, locate rare books, establish a sequence of editions, and so on are lacking in crucial tools for revising the canon.
To address such concerns, an experimental version of the traditional scholarly methods course was designed to raise students’ consciousness about the usefulness of traditional learning for any modern critic or theorist. To minimize the artificial aspects of the conventional course, the usual procedure of assigning a large number of small problems drawn from the entire range of historic

[不定项选择题]共用题干
第一篇
A recent study,published in last week's Journal of American Medical Association,offers a picture of how risky it is to get a lift from a teenage driver. Indeed,a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone,by contrast,the risk of death for drivers between 30 and 59 decreases with. each additional passenger.
The author also found that the death rates for teenage drivers increased dramatically after 10 pm,and especially after midnight.With passengers in the car,the driver was even more likely to die in a late-night accident.
Robert Foss,a scientist at the University of North Carolina Highway safety Research Center, says the higher death rates for teenage drivers,have less to do with"really stupid behavior" than with just a lack of driving experience."The basic issue,"he says,"is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is."
Both he and the author of the study believe that the way to mitigate(使······缓解)the problem is to have states institute so-called graduated licensing systems,in which getting a license is a multistage process.A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult,followed by a period of driving with passenger restrictions,before graduating to full driving privileges.
Graduate licensing systems have reduced teenage driver crashes,according to recent studies. About half of the states now have some sort of graduated licensing system in place,but only 10 of those states have restrictions on passengers. California is the strictest,with a novice(新手)driver prohibited from carrying any passenger under 20(without the presence of an adult over 25)for the first six months.
A graduated license is issued to a driver who________.
A.is at least a middle school graduate
B.has learned driving at a driving school
C.gains full driving rights step by step
D.has a driving experience long enough
