Step 6 Pronunciation--stressed syllables

规则

音节是英语当中最小的单位。每个音节含有一个音节核，通常由元音音素构成，辅音是音节的分界线。所以，音节就分成单音节、双音节和多音节。

1. 单音节词

1. 两辅音之间不管有多少个元音，一般都是一个音节。如：bed，seat， beau'ty。
2. 两元音字母之间有一个辅音字母时，辅音字母归后一音节，如：stu'dent，la'bour。
3. 有两个辅音字母时，一个辅音字母归前一音节，一个归后一音节，如：let'ter，win'ter
4. 不能拆分的字母组合按字母组合划分音节。如：fa'ther，tea'cher。

2. 双音节词

一般在第一个音节重读。如：sorry, movie, cover

1. 有 a-, be-, de-, re-, res-, in-, im-, en-, em-, es-, ex-, con-, com-, dis-, mis-, pre-, per-, pro-, trans- 等前缀的词，第二个音节是重音。如： be'lieve, de'cide
2. 有 de-, in-, re-, con-, 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，其它的词性在第二个音节上。如：'present   pre'sent
3. 有些复合词和带有前缀 re-, ex-, un-, pre-, post-, 等的词，有两个重音。如：ˌout'side, ˌre'tell

3. 多音节词
       一般倒数第三个音节是重音。如：'difficult, oppor'tunity, 'family, e'conomy, uni'versity

    练习
1. 画出重音和次重音，然后读给同桌听。    代表重音，    代表次重音，    代表非重音。

alarming, announcement, authority, architecture, civilization, competition, contribution, electricity, investigate, literary, recommend, responsibility, vocabulary, volunteer, refrigerator, habitat, downstairs

3. 听下面的对话，注意多音节词的重音，并跟读。

A: I'm concerned about the blue whales. What do you know about them?

B: Well, I know that they're being hunted and their number is getting dramatically smaller, so they're in danger of extinction. Elephants need large living spaces, so it's difficult for them to adapt to the changes.
