单选题 . ①In 1876 Edmond Duranty dubbed the style of emerging French Impressionist artists "The New Painting". ②More than a style, the Impressionists' luminous landscapes were regarded as a new way of seeing. ③Of course, it was not wholly new. ④The English painters Constable and Turner, whose work French artists knew, had already painted out of doors earlier in the century and brilliantly sought to capture the impact of natural scenes on their sensibility. ⑤Courbet's toughminded realism and Jongkind's harbor scenes also had much to teach the emergent movement. ⑥The Impressionists never denied this ancestry; but they were aware, too, that they had taken these painters' unconventional experiments to unfamiliar levels and, consolidating themselves as a movement, had indeed made painting new.11. Which of the following best describes the function of the highlighted sentence? ______

A、 It provides support for an assertion made previously in the passage.
B、 It undermines a claim made earlier in the passage.
C、 It questions the usefulness of categorizing artists into particular movements.
D、 It identifies painters whose works were praised by some Impressionists.
E、 It suggests that painting out of doors was unusual during the early 1800s.

【正确答案】 A

【答案解析】 A：本题属于功能题，定位句3s版本是“印象派受其他人影响的例子”，因此其功能是用来支持前一句认为“印象派并不是全新的”，所以选项A正确。an assertion made previously in the passage对应第③句。
B：定位句是例子，所以无法用来“削弱”，且这句话所支持的第③句是让步句，undermine一词程度太强。
C：同选项B，选项C的question也程度太强。
D：文中未提及。
E：文中未提及。
