[知能为先——必备知能一站明]

如何辨别句子的重音

句子的重音是有规定的。一般情况下，实词，如名词、行为动词、形容词、副词、数词、疑问词及感叹词都应该重读；而功能词，如连词、介词、冠词、助动词、情态动词、人称代词等都不重读。但是，在实际的对话中，说话人可根据说话的目的及其意图灵活地对任何单词或短语加以重读以进行强调。

Thestudentsarehonestanddiligent.(这句话中的students是名词，honest和diligent是形容词，它们都要重读。the,are,and不重读)

Iamsogladtohearthat.(这句话中的so,glad,hear,that要重读，而I,am,to不重读)

但是，在下列情况句子中的虚词及助动词也要重读：

1．强调或突出某个虚词或be动词时，应将其重读。

Wesawhimplayingontheplayground.(这句话中的We和him一般不重读，但为了表示强调要重读)

2．介词在句首时往往要重读。

Intheclassroom,thereisacomputer.(这句话中的In在句首，应重读)

3．be动词及助动词和not结合时要重读。

Didn'theseeyouyesterday？(这句话中的Didn't要重读)

4．句子末尾的be动词和助动词一般要重读。

—Areyouateacher

—Yes,Iam.(这句话中的am要重读)

[指津]上文刚出现过的并且重读的单词，第二次提到时一般不再重读。

—Howmanydesksarethereintheroom

—Therearefiftydesksinit.(问句中的desks重读，但答语中的desks不再重读)

掌握了辨别句子重音的能力，就能很快抓住说话者的目的和意图，就能准确地抓住话语的中心内容和要点，从而快速地做出正确的反应和判断。

[训练为重——能力提升多听说]

Ⅰ.朗读下列句子，并写出其中需要重读的虚词或助动词

1．Wesawhimplayingbytheriver.(by)

2．Onmywaytoschool,mybikewasbroken.(On)

3．I'msorryIcan'tdothat.(can't)

4．Didn'tItellyouyesterday？(Didn't)
