参考答案
1、答案：B
解析：细节理解题。根据第四段的内容可知饮用夜间取的牛奶的老鼠比饮用白天取的牛奶的老鼠不那么活跃、不那么焦虑。故选B项。
2、答案：D
解析：推理判断题。文章中提到晚上挤的牛奶里的褪黑激素含量是白天挤的牛奶里的10倍,并不是说研究人员在老鼠身上测试了10次,所以A项错误;由第二段中的" peple feel sleepy and reduce anxiety."可知褪黑激素不可能使人更加精力充沛,故排除B项;由第二段中的"...'night milk' cntains mre melatnin..."可知,并不是所有的牛奶中都含有大量的褪黑激素,故排除C项;由第六段中的"taking melatnin drugs has been suggested t thse wh are struggling t fall asleep at night"可推知,褪黑激素被用于安眠药中,故D项正确。
3、答案：A
解析：主旨大意题。根据第二段可知,饮用在夜间取自奶牛的牛奶能帮助人们入睡,减少焦虑。故选A项。
4、答案：D
解析：篇章结构题。本文是通过提供研究结果来支持第一段所提出的中心论点。故选D项。
5、答案：GBFCE
解析： 语篇解读:本文讲述了Sarah获得了亚马逊公司的创新发明大奖,并介绍了她有这方面理念的过程。
①解析:根据上文的信息"Sarah Hutchins has wn a prize frm Amazn. cm in a cmpetitin fr yung inventrs."可知Sarah参加了该比赛,故本题选G项合适。
②解析:根据上文的信息"I was sitting a lng way frm the stage and I was watching the band thrugh my binculars."可知,Sarah在参加音乐会的时候,位置离舞台太远。她就想到要发明一种工具,既可以看到远处的东西,也可以拍摄到,故B项和上文的意思一致。
③解析:根据下文的信息"S Sarah sent her idea t Amazn. cm and tw mnths later, she gt a surprise."可知她姐姐告诉她比赛的消息,故选F项。
④解析:根据下文的信息"They didn't give her the tp prize in the cmpetitin, but she wn $ 1,000 and a trip t New Yrk."可知,此处告诉我们获奖情况。那么空处应该讲述亚马逊通知她获奖情况,故C项正确。
⑤解析:上文的信息"If yu just sit there and think, yu wn't invent anything, because yu get ideas at strange mments."告诉我们如果我们只是坐在那里,是无法发明任何事物的,所以我们要行动起来,往往在一些特殊情况下,我们才会有一些奇特的灵感,故E项符合上下文的逻辑关系。

7.这时（when)施工才几个月。when引导时间状语从句。since自从; befre之前； until直到……为止。
8.华盛顿受了伤(injured)，大脑受到损伤。根据brain damage可知，选A。dead死亡的； sad悲伤的； nervus紧张的。

7、答案：①has imprved②r③an④t make⑤tighter⑥what⑦traditinal⑧flexibly⑨is bradcast/is bradcasted⑩mving
解析：①考查时态。句意:尽管随着平板电视的发展,西面质量有了很大的提高,但声音却下降了。空处为状语从句的谓语动词,结合语境和主句渭语动词has taken判断为现在完成时, imprve一般用主动形式表被动意义,主语quality不可数,助动词用has.故填has imprved.
②考查连词。句意:问题是,屏幕变薄的电视没有足够的空间安装像样的扬声器,无论是在背面还是在边框。结合句意表达"要么……要么……",用…,故填r。
③考查冠词。句意:这种电视通常连接到外部声音系统,例如声音酒吧或家庭影院系统,以使其音频质量更好。system"系统"是可数名词,此处为泛指,应用不定冠词修饰,且external的发音是元音音素开头,故填an。
④考查非谓语动词。句意同上。句子谓语动词是are cnnected t,且无连词,故空处为非谓语动词:结合句意表示目的用不定式。故填t make。
⑤考查比较级。句意:早期电视的扬声器和屏幕一样大,但工程师们已经很擅长将扬声器变小,并将其放入更紧凑的空间。结合上文smaller可知,此处是指更紧凑的空间,应用比较级tighter修饰名词spaces.故填tighter。
⑥考查宾语从句。句意:索尼是第一家开发"声学表面"的公司。空处引导宾语从句,从句谓语动词calls后缺少间接宾语,指代事物,应用连接代词what。故填what。
⑦考查形容词。句意:不像传统的屏幕,这个屏幕直接发光。修饰nes应用所给词的形容词形式,故填traditinal。
⑧考查副词。句意:这意味着它能够更灵活地振动。修饰动词vibrate应用所给词的副词形式。故填flexibly。
⑨考查时态语态。句意:一个有益的结果是,节目的音乐直接向观众而不是从侧面播放。空处为表语从句的谓语动词,陈述客观事实,且主语music和bradcast是被动关系,应用一般现在时的被动语态, 主语是单数,故填is bradcast/bradcasted.
⑩考查动名词。句意:它也可以通过移动声音的原点在屏幕上产生立体声效果。介词by后应用mve的动名词形式作宾语。故填mving。
