正确答案: A

小李在图书馆内，则小黄没有去公园散步

题目：只有小王陪伴，小黄才到公园散步。如果小王不去图书馆，那么小李也不去图书馆。由此可以推出以下哪项结论( )。

解析：此题考查假言命题的推理规则。题干中的命题转换为推出形式为：小黄到公园散步一小王陪伴（在公园散步），小王不去图书馆一小李不去图书馆。A项小李在图书馆，根据假言命题推理规则，否定后件就能否定前件，可知小王在图书馆，则小王不在公园散步，同理推出，小黄没有去公园散步，A项正确；B项否定前件不能否定后件，错误；C项肯定后件不能肯定前件，则不能确定小王的动向，无从推出小黄的行动，错误；D项肯定后件不能肯定前件，错误。故选择A项。

不合理，教师应认真批改作业

解析：根据《中小学教师职业道德规范》（2008年修订）中"爱岗敬业"的要求，教师应对工作高度负责，认真备课上课，认真批改作业，认真辅导学生，不得敷衍塞责。题中描述的曾老师，对于学生作业的检查就只是核对答案，无法从作业中判断学生的学习掌握程度而发现学生可能存在的问题，这是对工作敷衍的表现。他的这种行为不合理，教师应该认真批改作业。

[单选题]22.请阅读Passage 2,完成第1～5题。 　　Passage 2 　　teacher education provided by U,S.colleges and universities has been routinely criticizedsince its inception in the early nineteenth century,sometimes deservedly.These programs,like non-university programs,are uneven in quality and can be improved.What makes today's criticisms different is an aggressive effort by advocacy groups,and self-proclaimed educational entrepreneursto deregulate the preparation of teachers,and to expand independent,alternative routes intoteaching. 　　This effort to “disrupt” the field of teacher preparation in the United States has gainedconsiderable “momentum” and legitimacy,with venture capitalists,philanthropy,and the U.S.Department of Education all providing sponsorship and substantial funding. 　　The strength of this effort is that the United States may quickly seek to dismantle its universitysystem and replace much ofit with independent,private programs.The resulting system of teacherpreparation may differ dramatically in its government,structure,content,and processes moving away from its current location alongside legal,medical,and other professional preparation that pairsacademic degrees with professional training. 　　Throughout the nation,states are reporting teacher shortages in particular subject areas andgeographical locations,and several states have either passed legislation to lower the standards for becoming a teacher or,like the state of Washington,have looked toward expanding the number ofteacher education providers to try to fill teaching vacancies.The federal government has contributedto the push to lower standards for becoming a teacher with the teacher Preparation Academyprovision in the new K-12 education law,the Every Student Succeeds act,which encourages statesto expand the number ofindependent programs not associated with colleges and universities. 　　Because of the increasing tuition rates,a consequence in part,of cuts in funding to publicuniversities that continue to educate most U.S.teachers,enrollments in college and universityteacher education programs have declined in many parts of the country.Independent teacher education programs are being viewed by some as an important part of the solution in staffing thenation's classrooms and addressing our serious and enduring problems in education inequities.Additionally,advocacy groups,philanthropists,and so-called education entrepreneurs are working aggressively to expand these independent alternative routes into teaching. 　　Given the seriousness of the teacher shortage problem in the United States and the substantialmedia attention that has been given to independent teacher education programs as the solutionto teacher shortages and education inequities,policy makers should very carefully examine the evidence that exists about the nature and impact of these relatively new programs that are rapidly expanding while university teacher education enrollments decline.

What can be inferred from Paragraph 3?

The new teacher education programs will follow the usual practice of other professionalpreparation.

解析：推断题。根据第三段末尾“The resulting system of teacher preparation may differ dramatically in...moving away from its current location alongside legal,medical,and other professionalpreparation”可推断出，新的师范教育项目会遵照其他职业教育的惯例，故D项正确。A项“美国的高等教育系统会完全瓦解”，该说法过于绝对。B项“美国高等教育系统将会被完全调整”，根据第三段第一句中“theUnited States may quickly seek to dismantle its university system and replace much ofit with independent,privateprograms”可知，只是大部分会被调整，而不是完全调整。C项“未来私立师范项目将不会为师范学生颁发学位证书”，文中未提及。故本题选D。
