Step 11
Accent skill
在遇到一个新单词时，一般情况下，最可靠的办法是查字典，按照音标来读音。不过，有一些单词的重音是可以找到规律的，可以根据它们的拼法、前后缀等来判断。
以下一些规则可供学习重音时参考：
1.在英语中，许多常用名词和动词重音往往在第一个音节上。例如:
English language learner students
father mther teacher peple
sister brther family pretty
2. 带有前缀 be-, in-, dis-, ex-, un- 的双音节和多音节词，重音几乎都落在第二或第三个音节上，因为英语的前缀是不重读的。例如：
becme invite distract expect
discver infrm exclude und
begin unlck disclse explde
3. 英语所有词的后缀都不重读。
-ly cmfrtably carefully
-al natinal ratinal
-tive active preventive
-ent/ant silent pleasant
-ic heric autmatic
4. 单词加上后缀 -able 以后，重音保持不变
rely reliable
depend dependable
adapt adaptable
detest detestable
knwledge knwledgeable
demnstrate demnstrable
5. 英语中有一类词拼写是一样的，但一个是名词，一个是动词。这类词中，所有名词的重音都在第一个音节上，所有动词的重音都在第二个音节上。例如:
cntest cntract discunt extract
imprt cnflict digest exprt
present prtest recrd prduce
survey refuse subject bject
Students learn the accent skill and read the wrds alud.
Get the accent skill and prnunciatin skill.
