[简答题]sentence stress

参考答案:Sentence stress refers to the relative force given to the words of a sentence. In English the words that are normally stressed are nouns, main verbs, adjectives, adverbs, and demonstrative pronouns, but to give special emphasis to a certain notion, a word in a sentence that is usually unstressed can be stressed.
答案解析:[解析] 句子重音指的是句子中不同单词之间相对的发音的强弱。在句子中，一些单词比另外一些单词要重要得多，那么这些重要的单词发音的时候需要用较大些的音强以使其更加明显、突出。英语中较为重要的单词为名词、主要动词、形容词、副词以及指示代词等，其他范畴内的词类如冠词、人称代词、助动词、介词和连词等一般不会重读。为了强调某个概念，句子中通常不会被重读的单词也可以重读。
