主謂一致中的靠近原則

1）當(dāng)there be 句型的主語是一系列事物時(shí)，謂語應(yīng)與最鄰近的主語保持一致。 There is a pen, a knife and several books on the desk.. There are twenty boy-students and twenty-three girl-students in the class.

2）當(dāng)either… or… 與neither… nor，　連接兩個(gè)主語時(shí)，謂語動(dòng)詞與最鄰近的主語保持一致。 如果句子是由here, there引導(dǎo)，而主語又不止一個(gè)時(shí)，謂語通常也和最鄰近的主語一致。 Either you or she is to go. Here is a pen, a few envelops and some paper for you.
