65. Photographer Edward Steichen constantly experimented new techniques and materials in his quest to have photography accepted as a creative art. 答案：A. à experiment with new

分析及考点：此题较隐蔽。experiment做动词时为不及物动词，后须加介词with，为固定搭配。

参考译文：摄影师Edward Steichen不断地试验各种新技术和新材料，以期使摄影作为一门创造性的艺术为人们所接受。

答案是B，但是C同样有问题，查longman字典：后不能接to，望指点。

[countable] literary

1

a long search for something that is difficult to find

quest for

his long quest for truth the quest for human happiness World leaders are now united in their quest for peace.

2

Photographer Edward Steichen [constantly] experimented new techniques and materials [in his quest] [to have photography accepted as a creative art]

句子主干：Edward experimented new techiques.谓语experiment 为vi.

固定搭配：experiment with sth.

in one's quest 在某人的探索中。后面部分和这个探索没有关系，是整个句子的目的状语。

如果quest用为动词为：2，quest(vi) for new techniques and materials

名词：1，in quest of new techniques and materials
