关于英语阅读理解主观题（critical reading）怎么答?
考研到冲刺阶段了,可是综合英语的阅读理解主观题（critical reading）我却不知道怎么答是好,甚是困惑,比如它问你：In the above description by what means does the writer reveal his attitude and tone?
What can you infer from the last sentence?
真题没有答案,又找不到相关习题去练习,陷入绝望之际,还好能求助于百度.谁能介绍我一点相关练习给我做哦.....拿一个真题作例子：
(1)
Hidden away in back-country pockets of upper New England lie the last remnants of a type of agriculture that once covered the greater portion of the Northeast.These are the few remaining small-family hill farms of Vermont,New Hampshire,and Maine.Their existence is an anachronism; too remote to be easily reached from Boston or New York,lacking the proper terrain for a ski resort or the necessary shorefront for a second-home development,these farming enclaves have retained much of their original character.And they still exhibit a sense of harmony between man and his natural surroundings.
1.Write a complete sentence in your own words stating the main idea.
2.Why does the writer use the word ‘anachronism’?
