□单词重音的规则一、双音节词1．一般在第一个音节重读。如：'letter，'srry等。2．有 a－， be－， de－， re－， res－， in－， im－， en－， em－， es－， ex－， cn－， cm－， dis－， mis－， pre－， per－， pr－， trans－等前缀的词，第二个音节是重音。如：a'but, be'lieve, ad'dress, de'cide, re'prt, res'pect, in'frm, im'press, em'ply, es'cape, cn'cern, cm'pare, dis'cuss, mis'take, pre'pare, en'danger, per'mit，pr'duce, ex'tinct, trans'late 等。
3．有 de－， in－， re－， cn－， pre－等前缀的重音与词义和词类有关， 一般名词的重音在第一个音节上，其他的词性在第二个音节上(有的读音也有差异)。如：'recrd, re'crd; 'insult, in'sult; 'cnduct, cn'duct; 'present, pre'sent; 'cntent, cn'tent 等。
二、多音节词1．多音节词通常重读倒数第三个音节，也就是说，假如这个词只有三个音节，那就应该重读第一个音节，如：'accident, 'Africa, 'Italy, 'family, 'favrite等。如果有四个音节，就要重读第二个音节。如：A'merican, bi'lgy, in'telligent, 'pinin, de'licius等， 以此类推。2．双音节词加上前缀或后缀所构成的多音节词，重音一般在原来词根的重读音节上。如：ex'change, un'friendly, 'dangerus, re'quirement, 'fficer, 'usually等。
3．多音节复合名词通常重读第一个音节。如：'basketball, 'galkeeper, 'interview, 'newspaper, 'sunglasses等。4．词尾有－tin, －sin或－ian的多音节词，其重音一般在－tin, －sin或－ian前面的一个音节上。如：appli'catin，de'cisin; I'talian等。但'televisin例外。
三、次重音朗读单词时，按照发每个音时呼出气流的强度，我们通常可把重音分为主重音和次重音两类。所谓主重音，就是我们平常所说的重读音节，可在其左上方标上重音符号“'”来表示。而次重音，发音时呼出的气流比主重音稍弱一点，但比非重读音节强得多，我们常在此音节的左下方标 “'”来表示。一般来说，从重读音节算起的倒数的第三个音节处就是次重音。如：appli'catin, infr'matin等。
