At least, this is the conclusion __5__ (reach) by a team of scientists led by Greg Bryant, __6__ assistant professor of Communication Studies at the University of California, Los Angeles. The researchers began by __7__ (request) volunteers from across the world to send them audio clips (音频短片) of people laughing. The 48 tapes they received __8__ (range) from recent recordings of laughter between two college friends __9__ ones from conversations made ten years ago. The clips also had all possible __10__ (combine)—communications between friends, strangers, all­male groups, all­female groups, etc.
Bryan says that the results of this cross­cultural examination show that people all over the world know laughter in similar ways.

篇章导读：本文是一篇说明文。文章说明笑声在全世界表达的意义相近。
1.is expressed　考查动词的语态。句意：一般来说，快乐是通过笑声来表达的。本句表述一般性事实，故用一般现在时，主语joy与动词express为被动关系。故填is expressed。
2.that　考查同位语从句的连接词。句意：但事实证明，笑声揭示的不仅仅是你快乐的事实。fact后接同位语从句进一步说明fact的详细内容，同位语从句句子成分语意完整，所以用连接词that。
3.to realize　考查非谓语动词。句意：它让听众，甚至那些看不到你的人，意识到你是和一个亲密的朋友玩得开心，还是对一个完全陌生的人礼貌地笑。enable sb. to do sth.“使某人能够做某事”。故填to realize。
4.politely　考查词性转换。应用副词修饰动词laughing。故填politely。
5.reached　考查非谓语动词。句意：至少，这是由洛杉矶加州大学传播学一名助理教授格雷格·布莱恩特领导的一个科学家团队得出的结论。conclusion与reach在逻辑上是被动关系，所以用过去分词作后置定语。故填reached。
6.an　考查冠词。assistant professor为可数名词，且assistant首字母的发音为元音音素。故填an。
7.requesting　考查非谓语动词。句意：研究人员首先要求来自世界各地的志愿者给他们发送人们发笑的音频短片。by doing sth. “通过做某事”。故填requesting。
8.ranged　考查动词的时态。描述过去发生的动作且在句中作谓语，句子用一般过去时。故填ranged。
9.to　考查介词。句意：他们收到的48盘磁带从最近两个大学朋友之间的笑声录音到十年前的对话录音不等。range from ... to ... “范围从……到……”为固定短语。故填to。
10.combinations　考查词性转换。possible形容词修饰名词combination，且根据句意，可知这些短片有很多组合。故填combinations。
Ⅳ.短文改错

难项分析：
第三处：begin→began　考查动词的时态。由上文中的“last Sunday”可知，事情发生在过去，故用一般过去时。
第六处：amusing→amused　考查形容词。amused意为“感到有趣的”，一般形容人，而amusing意为“逗人发笑的”，一般修饰物。故把amusing改为amused。
第七处：such→so　考查副词。so/such ... that ... 意为“如此……以至于……”，so修饰形容词、副词，而such修饰名词。此处修饰lost，故用副词so。
