We pay special attention to the simple present tense and the auxiliary verbs:be,do / does and have / has. 为了确保谓语动词和助动词在人称和数上与主语保持一致,我们需要改变谓语动词或助动词的形式。特别要注意一般现在时和助动词:be,do/does和have/has。In the simple present tense,the subject determines if we need to add -s to the predicate verb.在一般现在时的句子中,主语决定谓语动词是否需要加s。• He knows that some people are smart.(We add -s to show the subject is singular.)• They know that some people are smart. (We do not add -s,because the subject is plural.)In other tenses,the auxiliary verbs be,do and have ensure the subject agrees with the verb.当句子是其他时态时,助动词be,do和have 使主语与动词在人称和数上保持一致。• We have been losing brain cells every day. (The verb have shows the subject is plural)• He has been reading the book. (The verb has shows the subject is singular.)When the conjunction or appears in the subject,the noun closest to the predicate verb takes the agreement.当主语中出现连词or的时候,谓语动词的数与其最靠近的名词保持一致。• The boy or his friends run every day. (Since the closest noun friends is plural,the verb agrees with the plural noun.)• His friends or the boy runs every day. (Since the closest noun the boy is singular the verb agrees with the singular noun.)When any of these words appear in the subject, the predicate verb agrees with the subject in the same way as a singular noun:verb-ing form,each,either,neither,everyone,anyone,nobody and no one. 当句子的主语是动-ing 形式,以及 each,either,neither, everyone,anyone,nobody,no one 等词时,谓语动词采用单数形式。• Each of the children gets a book to read.• Writing your notes clearly helps you remember the things betterHowever,if modal verbs come before the predicate verb or the auxiliary verb,we do not change the verb; we use the bare infinitive. 但是,如果句中的谓语动词或助动词前面有情态动词,谓语动词用原形。• He swims every day. (Since there is no modal verb,we add -s to the verb to show the subject is singular)• He can swim. (The modal verb can does not allow us to add -s to the verb to show the subject is singular.)选择正确的答案1. The old man planned ___________(to build/ building) a new house the next year. 2.
