2.The temporary camps that the author “I” prefers are usually _.
A.permanently located
B.simply equipped
C.elaborately decorated
D.specially designed for boys
正确答案：B
解析：原文第二段末句：’I prefer the latter, and I am sure the boys will agree with me.’ 前文指出 ‘Temporary camps are the ones we are considering, and these can be elaborate or very, very simple. I prefer the latter…’，’latter’ 指代 ‘very, very simple’，即简单装备的临时营地。
解析：原文第三段：’Small dog tents, like the ones our soldiers carried in the Civil War, are cheap and very convenient. Each man carried a section, and two made a tent, into which two men crawled when it rained…’，明确说明两个部分组成一顶帐篷，可容纳两人。
5.We can learn from the passage that camping is _.
A.great fun for adults
B.delightful yet challenging
C.boring and dangerous
D.an expensive outdoor activity
正确答案：B
解析：全文描述了生火技巧（含无火柴时的摩擦取火）、营地类型选择、简易庇护所搭建、迷路应对等实践性内容，体现其愉悦性（如 ‘roaring fire’, ‘best way to camp’）与挑战性（如 ‘green or wet wood’, ‘get lost’, ‘need skill’），B项最全面准确。
6.We can learn from Paragraph 1 that Berry 5.1 is _.
A.an indoor vertical farm
B.a BlackBerry smartphone
C.a strawberry picking robot
D.a clock-punching farmhand
正确答案：C
解析：原文第二段首段：’The New Yorker writes about Berry 5.1, which has so far cost $10 million to design and would pluck strawberries more precisely than clock-punching farmhands.’ ‘pluck strawberries’ 明确表明其为采摘草莓的机器人。
7.The word “claim” in Paragraph 1 is closest in meaning to _.
A.right
B.request
C.allegation
D.statement
正确答案：D
解析：原文中 ‘many of these kinds of articles end with the rather generic claim…’，此处 ‘claim’ 指文章提出的概括性论断，属中性表述，与 ‘statement’（陈述）语义最接近；’allegation’ 含负面暗示（指称未证实的指控），不符语境。
8.The robotics of “precision agriculture” will be _.
A.easy for farmers to handle
B.labor-consuming for farming
C.far beyond what farmers can afford
D.data-based technology that farmers like to use
正确答案：C
解析：原文第二段：’none of which are cheap, all of which will require maintenance that farmers may not be able to do themselves. Altogether, it will drive farmers deeper into the debt they already carry.’ 表明成本高昂、维护困难、加剧债务，故C项准确。
