2. Summarise the rules f stressed syllables accrding t the abve examples.(1)一般两个或三个音节的单词,重读在第一个音节上。但如果这个单词是带有前缀的,则重读在前缀后。如:(2)三个或以上音节的单词,重读在倒数第三个音节上。如:(3)带有后缀的单词,重读在这些后缀的前一个音节上(以下后缀除外:-ed、 -es、 -er、 -est、 -r、 -ary、 -ry、 -ment、 -us、 -cy、 -ry、 -ty、 -al、 -ure、 -ute、 -ble、 -ar、 -ly、 -less、 -ness、 -ful、 -ing)。如:
单词重音 一个英语单词,如果只由一个音节组成,就不存在重音或轻音的问题。如果由两个或两个以上的音节组成,就产生单词重音。念得特别响的音节,就是单词重音所在,也就是重读音节。其他音节叫非重读音节。除了一些复合词外,一般一个词只有一个重读音节,用 符号来标注。
(1)以下后缀会将重读吸引至其本身变成主重读(primary stress),而原重读降为次重读(secndary stress):-ain、 -ee、 -eer、 -ier、 -ade、 -ival、 -itis、 -mental (-ental)。如: refuge →refugeeemply →emplyee
