2.语文
一篇也是之前库的鸡精,关于14世纪F地女性有没有被legal guardship by 父亲、兄弟、丈夫,一个学者的观点基于一本书,然后一个叫kitte的学者反驳这个书不能成为这个观点的论据
一篇是关于发明投入在小公司和大公司之间产生效益的不同,D&R部门还是啥,小公司的innovation投入会产出更多新产品,我记得好像之前也在其他库看到过
一篇是关于什么运动音乐学还是啥,开篇说娱乐是人类特有的行为,在其他nonhumman mammal中不常见,然后说一个实验关于让人们根据节奏按tone,音乐训练会显著提高正确率,另一个发现是人们都会在后面自己纠正节奏错误,但没受过训练的人deliberately来纠正自己的错误(大概有意识的纠错),受过训练的人会有另一种纠正方式(好像是潜意识还是无意识地自己纠错)
CR遇到了cr200真题的第200题,建议有时间可以都过一遍(附cr真题),确实是gmac的出题风格
200. Although Bernini became famous as a sculptor, he was also a painter. It is likely, however, that his painting was a sideline. One reason for thinking this is that none of his surviving paintings seem to have been commissioned. For one thing, the paintings are unsigned. Also, many of them are self-portraits, and _______.
Which of the following, if true, most logically completes the argument?
A. Self-portraits by Bernini would not have been commissioned
B. many of the most accomplished painters have painted-portraits
C. it is possible to determine the artist of unsigned paintings
D. it is not uncommon for painters to leave their works unsigned
E. self-portraits would not need to be signed
