Without a little planning, you may【C1】______ specific environmental and social issues in a given location.

Airplanes and cars【C6】______ significant amounts of greenhouse gases to the atmosphere. Walk or bicycle as much as possible—a good method of【C7】______yourself in your destination. Electric trains and buses are also examples of more efficient and cleaner【C8】______of mechanized travel.
    Secondly, investigate the agencies you may choose for your trip to find out their practices and reputations. Ask the company【C9】______ what they do for the local community and【C10】______ they run their operations. Some may contribute little economically to the area or they may【C11】______ engage in ecologically damaging practices,【C12】______ fuel-costly tours or excessive harassment of wildlife in the name of sightseeing.

【C1】
选项 A、resolve
B、neglect
C、initiate
D、concern
答案B
解析 动词辨析题。句意为：如果不做一些计划，你可能会忽视某个特定地区特有的环境和社会问题。结合上一句含义：即使在充分放松的假期，也应该注意可能造成的环境影响，以及本空所在句句首的without a little planning，可知本句是从反面来论述，因此应选择与前一句“be aware of”意义相反的词，neglect“忽视”符合句意，故为答案。resolve“解决；决心”、initiate“开始；发起”、concern“涉及；使担心”均不能与前句的“意识到”形成相对含义，因此排除。
