24、battendcattachdtalk()14a. hatebscoldcfrightendstop()15a. lovingbobservingcunderstandingdpraising【语篇导读】本文首先指出父母与十几岁的孩子之间存在矛盾冲突及其原因，然后是研究发现的不同父母采取的不同方法，有的方法较另一些方法更有效果，最后一段是心理学家对解决冲突给出的建议。1d根据第一句中的difficult以及第二句中的again和 “not easy”可知青少年和父母有相似的感觉。2b由第一句 “parents feel that it is difficult to live with tee

25、nagers. ”可知，父母和孩子之间相处困难，他们之间有争论，即对事物有不同的看法(argument)。3c根据上文untidiness和 “daily routine tasks”，填空所在的句子和后文的 “clothes thrown on the floor and their childrens refusal . . . ”形成并列关系，可知用messy。4b与上文说的孩子把家弄乱，到处乱扔衣服并列的应是拒绝帮忙做家务。5c与后文不打扫房间，不去买东西并列，即把毛巾丢(drop)在浴室。6a根据后句中 “some approaches”，可知选a。句意：不同的家长有着不同的解决问题

26、的方法(approach)。7d由下文中的better可知，有些方法较为成功。8a父母责骂他们乱，但稍后(later)就为他们整理房间，这样几乎没有机会改变他们孩子的行为。9a从下文多次出现的actions可知。10c根据下文所举的例子“不帮父母去买东西的话在冰箱里就找不到自己最喜欢的饮料”可知，这是让孩子“感受到自己的行为产生的后果”。11d根据 “are forced to”可知，孩子们被迫重新考虑自己的行为。12a根据本段倒数第二句出现的 “communication is a twoway process. ”以及上文一直强调父母与孩子应如何沟通，可知选a项。13d“talk to”与

27、say是同义复现，即父母要向孩子说出(talk)他们的想法，同时也要倾听孩子的想法。14b由上文的blame可知，当父母看到孩子把家里弄乱时会责备他们，所以选b项。15c只有通过倾听和相互理解(understanding)，父母与孩子之间的问题才可得到解决。语法填空wu zetian, the only woman emperor to rule ancient china, is considered 1_ one of the most powerful women in chinese history. she was born into a(n) 2_(wealth) family w
