【1】But
句意：但是每年，成千上万的人们合作只在四个月内建造新家。前一句表示一般建一座房子需要六个月，后一句表示只用四个月就建造一个新家，前后表示转折关系，故用连词but。
【2】wonderful
句意：谁做了这么精彩的工作？根据前文的thousands of people work together to build new homes in just four months!可知四个月就能把应需要六个月建造的房子建好，这是一个精彩的事，故为wonderful。
【3】need
句意：仁爱之家是一个团队，能为那些急需房子的家庭建造家园。in need需要的，故此处为need。
【4】free
句意：他们是不要报酬的工人，他们免费做所有的工作。根据前半句的unpaid可知此处表示不要钱，for free免费的。故此处为free。
【5】live
句意：150多万人住在这些房子里。live in“居住”，主语More than l．5million people是复数形式，故谓语动词用复数形式，故为live。
【6】how
句意：志愿者学会如何建墙。根据前一句的Building a home is hard work．可知建造一个家园是辛苦的工作，此处应学会如何建造房子。故用how。
【7】machines/materials
句意：他们使用许多机器和工具。根据与tools并列，故表示建房子需要材料或机器，有many修饰，故用复数名词，故为machines或materials。
【8】dream(s)
句意：每个人共同工作来使家庭梦想成真。根据come true可知此处表示梦想成真。故为dream或dreams。
【9】began
句意：她在中学时就开始成为志愿者。begin doing sth开始做某事，根据in high school.可知在她上中学时，此处应用一般过去时，故为began。
【10】if
句意：志愿者知道如果他们不帮助，家园可能无法被建成。此处表示假设，如果志愿者不帮助，那些需要家园的人无法建造房子，故此处为if。
