Question

    In the far corner of the front yard of a large house in Florida rests an RV—Recreational Vehicle( 活动房屋式旅游车), shaded by trees as clothing on a nearby line sways(摇动) in the breeze. In this RV, National Geographic explorer Thomas Culhane lives with his wife, Enas, almost entirely off the grid—a lifestyle without depending on electricity supply.

Culhane began living off the grid in the late 1990s, when he went into the basement of his apartment building in Los Angeles and pulled the plug that delivered electricity. Even earlier though, he was first inspired by sustainable(不破坏生态平衡的) living during a trip in 1970 to visit his relatives. He was eight years old and worried that his stay in their small village was going to be miserable because his relatives told him they had no air conditioning or electricity— but they had plenty of fresh fruits from orchards (果园) and lots of cold drinks chilled by the icy stream from the ice caps of the nearby mountain. “This is amazing,”says Culhane.

He met Enas when she was living in an ecovillage in Portugal. Enas said she liked the feeling of being low impact, of being harmless to the earth. Culhane was attracted and fell in love with her. The couple got married, living on the same property(财产) that they currently have. They moved into their first home together—an RV which they immediately took completely off-grid.

Inside their RV, Culhane and Enas have hot showers, a working gas stove, a refrigerator, a washing machine and a big screen TV. They use gas created by their on-site biodigesters (生物煮解器) to cook on a gas-powered stove. They also use energy created by the biodigesters to heat their bath water. They feed the biodigesters using their own food waste— at no additional cost to the earth.

Sometimes on weekends, the RV is turned into a classroom. The couple host workshops to let the community members and students know living an off-grid life is getting easier and teach them how to respect and coexist peacefully with the environment.

【解析】

本文为记叙文。本文主要叙述了Culhane和Enas这对夫妇为了给地球减负，不危害地球，在活动房屋式旅游车中过着一种完全不用电的自给自足的生活。他们还举办了研讨会，让社区成员和学生知道，远离电的生活其实并不难，并教他们如何尊重环境，与环境和平共处。

1.推理判断题。第二段第一句“Culhane began living off the grid in the late 1990s, when he went into the basement of his apartment building in Los Angeles and pulled the plug that delivered electricity”是本段的主旨句,可知，Culhane在上世纪90年代末开始过着不用电的生活，当时他住在洛杉矶公寓楼的地下室，拔掉了供电插头。”再结合本段的内容可知，本段主要介绍了Culhane一次探亲之行启发了他过不用电的生活方式 ，即他的环保生活的一些背景知识。故选A。

2.推理判断题。根据第三段中的“Enas said she liked the feeling of being low impact, of being harmless to the earth. Culhane was attracted and fell in love with her.”可知，埃纳斯说她喜欢那种对地球影响小、无害的感觉。卡尔汉被她吸引并爱上了她。再根据文章的内容可知，他们俩都喜欢这种不用电网的生活。由此可推断出，当Culhane第一次见到Enas的时候，吸引他的是他们共同的生活方式。分析选项可知B项符合题意，故选B。

3.推理判断题。根据倒数第二段中的“They use gas created by their on-site biodigesters to cook on a gas-powered stove. They also use energy created by the biodigesters to heat their bath water. They feed the biodigesters using their own food waste— at no additional cost to the earth.”可知，他们使用现场生物消化器产生的气体在燃气炉上做饭。它们还利用生物消化器产生的能源来加热洗澡水。它们用生物消化器分解自己的食物垃圾产生能源，而不增加对地球的负担。由此可推断出生物消化器可产生替代能源。故选D。

4.主旨大意题。通读全文，尤其是第一段最后一句“National Geographic explorer Thomas Culhane lives with his wife, Enas, almost entirely off the grid—a lifestyle without depending on electricity supply.”即“卡尔汉和他的妻子伊纳斯几乎完全不使用电网——一种不依赖电力供应的生活方式”；和第二段第一句中的“Culhane began living off the grid in the late 1990s” 即“卡尔汉从20世纪90年代末开始过着无电生活”；和最后一段中的“The couple host workshops to let the community members and students know living an off-grid life is getting easier”等可知，本文主要叙述了Culhane和Enas这对夫妇喜欢完全不用电网，住在活动房屋式旅游车中的自给自足的生活。综合全文可知，“living off the grid”贯穿全文，而B项（Living off the Grid）即为远离电网，符合题意，是最佳题目，故选B。
