单选题
Peter, perhaps John, ___ playing with the little dog.
A
seems
B
were
C
are
D
is
答案解析
正确答案:D
解析:
这是一道主谓一致及语义理解的题目。我们来分析并确定答案:
1. **主语分析**:
- 题干中的主语是“Peter, perhaps John”,即彼得,也许是约翰。这里涉及到两个可能的主语,但实际上表达的是一个不确定的单一主体(彼得或约翰中的某一个)。
2. **谓语动词的选择**:
- A选项“seems”虽然形式上看似符合单数第三人称,但语义上“seems playing”搭配不当,通常我们会说“seems to be playing”。
- B选项“were”是复数过去时,与主语的单数性质不符。
- C选项“are”是复数现在时,同样与主语的单数性质不符。
- D选项“is”是单数现在时。在英语中,当主语由“or”,“nor”,“either...or...”,“neither...nor...”,“not only...but also...”以及本题中的“perhaps”连接时,虽然涉及两个或两个以上的名词或代词作主语,但谓语动词的数仍取决于这些结构所强调的一个主语,即遵循“就近原则”或“意义一致原则”。在这里,“perhaps”暗示了不确定性,但动作执行者被视为单一主体,因此用单数动词“is”。
3. **语义理解**:
- 句子想要表达的是“彼得,也许是约翰,正在和小狗玩”。这里强调的是某一个人(不确定是彼得还是约翰)正在进行的动作,因此用单数动词“is”是恰当的。
综上所述,结合主谓一致和语义理解,正确答案是D:“is”。
