【解析】
【详解】
句意：不仅他的朋友，而且他总是对科幻小说感兴趣。考查主谓一致。not only…but also连接两个主语的时候，谓语动词的数由离其最近的主语来决定，即就近原则，所以此处要根据he来确定谓语动词的形式；因为后面是interested in，所以用be interested in“对…感兴趣”，所以谓语动词用is；故答案选D。
A．Neither; norB．Either; orC．Not only; but alsoD．Both; and
【答案】B
【解析】

12．Mr Jiang isn’t as busy as before because thereno home robot to help him．
A．used to beB．may beC．used to haveD．may have

【解析】
【详解】
句意：江先生不如以前忙，因为过去没有家用机器人来帮助他。used to be过去是，may be可能是，used to have过去有，may have可能有。There be句型，表示存在，意为“有”。根据Mr Jiang isn’t as busy as before可知此处指的是过去，故用used to be。故选A。

【点睛】
as well as, with, along with, like, together with, rather than, except, but, including, accompanied by, plus, besides, in addition to, no less than等引起的结构跟在主语后面，不能看作是并列主语，该主语不受这些词组引导的插入语的影响，主语如是单数，其谓语动词仍然用单数形式。例如：1）My mother, as well as my father, has a key to the office. 2）The man together with his wife and children sits there watching TV. 3）His sister no less than you is wrong. 4）The reading course book, plus its reference books, is helpful to college students.
A．Both; and
B．Neither; nor
C．Either; or
D．Not only; but also
【答案】D
【解析】句意：——《跑男》和《朗读者》，你更喜欢哪一个节目？——当然是《朗读者》，不仅我，而且我哥哥都喜复数形式。此处谓语likes是第三人称单数，故排除A项。Neither;nor“既不，也不”，根据The reader, of course可知此处表示喜欢《朗读者》，故排除B项。Either, or“或者，或者”，根据句意我和哥哥两个人都喜欢它，不是我们中的一个人喜欢它。故排除C项。Not only, but also“不仅，而且”连接并列主语，谓语用就近原则，离谓语最近的主语my brother是第三人称单数，故谓语likes是第三人称单数。故选D。

【答案】A

中考英语语法专项复习主谓一致主谓一致是中考英语的重要语法项目之一，从近年来中考的试题来看，中考主谓一致方面的考题主要考知识的记忆情况。

考查主谓一致的常见题型有单项选择，完型填空等。

做这类题时，必须找出句子的真正主语，然后根据记忆的知识作出判断。

同时，要遵循三个原则：语法一致、意义一致和就近原则。

以单数名词或代词，动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数主谓一致概述：谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。

主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。

1. 语法一致的原则(1)以单数名词或代词，动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数，例如：He goes to school early every morning.The children are playing outside.To work hard is necessary for a student.(2)由and或both……and连接的并列成分作主语时，谓语动词用复数。

例如：Both he and I are right.Mr Black and Mrs Black have a son called Tom.但并列主语如果指的是同一人，同一事物或同一概念，谓语动词用单数。

例如：His teacher and friend is a beautiful girl.The poet and writer has come.(3)由and连接的并列单数主语之前如果分别由each, every修饰时，其谓语动词要用单数形式。

例如：In our country every boy and every girl has the right to receive education.Each man and each woman is asked to help.(4)主语是单数时，尽管后面跟有but ,except, besides, with 等介词短语，谓语动词仍用单数。

10．—Excuse me. Is there a bank near here?

A．there isn'tB．it isn'tC．they aren'tD．there is
【答案】A
【解析】

句意：——劳驾，请问附近有银行吗？——没有。但你可以去阳坊路，那里有一家。
考点：考查连词用法辨析。
20．Mr Li，together with his children，the museum. They will be back this afternoon.
A．have gone to B．have been to
C．has been to D．has gone to
根据下文的答语“But you can find one in Yang Fang Road.”知是否定回答，排除D选项。根据问句“Is there…?”可知答语为there be句型否定形式，答案为A。
11．It’s said that ______ of the water around the world ______ polluted.
8．----Where would you like to go tomorrow, Beijing or Xi'an?
----is OK. It’s up to you.
A．EitherB．NeitherC．BothD．All
【答案】A
【解析】
【详解】
句意：——明天你想去哪里，北京还是西安？——两个都可以。由你决定。考查不定代词辨析题。either二者择其一；neither两者都不，表否定；both两者都；all全都。both和all都需用复数动词形式，和is不搭配，可排除CD两项。根据OK，可知是肯定句，故选A。

【点睛】
谓语动词的确定依据“就近原则”的有：there be＋句型; or ; either …or；nor; neither…nor；whether…or；not…but; not only…but also…等。
