Abstract: In English, correct pronunciation plays an important role when you want to convey what you mean. Speaking of pronunciation, suprasegmental phonology should be put into the first place to be discussed. Among suprasegmental phonology, stress is a kind of feature that is easy to be ignored. Many people who learn English pronunciation often think if they can read the word or sentence clearly, they can convey their meanings effectively. However, with wrong stress, people may easily get confused because they misunderstand what other want to convey. English stress can be put into different position depending on what people want to say. In all, having the awareness of correct stress helps a lot to make up effective conversations.

摘要：在英语中，正确发音在传递意义的过程中起着很重要的作用。提到发音，超音段音位必须要放到首位来讨论。在超音段音位中，重音是一种易被忽视的特征。很多学习英语发音的人认为只要做到吐字清晰，他们就可以有效让被人明白他们所要表达的意思。然而，如果人们读错了重音，他们很容易混淆别人的意思。在英语中，重音可以放在不同的位置来表达不同的意思，这只取决于人们想要说什么。总之，要有读对重音的意识，这样才能帮助自己有效表达。
