试题出自试卷《2015年西南科技大学考博英语真题》

问题1选项
A.as well as an effective teacher
B.and too a very efficient teacher
C.but he teaches very good in addition
D.however he teaches very good also

A

考查连词。A选项as well as“和……一样，不但……而且”，连接两个句子或者短语，例句：The girl is lively as well as healthy.(这女孩既健康又漂亮。），所以A选项正确；B选项and和too不连用，应该改为and a very efficient teacher too才正确；C选项but“但是”，表示转折，罗伯特是一个著名的化学家和很好的老师应该是并列关系，而不是转折，所以C选项排除，同理D选项however“然而”，也是表示转折，故排除。句意：罗伯特是一位著名的化学家，也是一位卓有成效的老师。综上所述，本题的正确答案是A选项。
