4.A:Neither of the twins is here.They went fishing just now(√) B:Both the twins are not here.They went fishing just now.( )
「析』在英语中 both 一般用于肯定句中,如用于否定句中,其意义也不同于汉语,如:Both of us are not right. 在英语中应被理解为“我们俩不都对。”而 Neither of us is right。才能被理解 为“我们俩无一正确”。故A 正确。
5.A:He or his classmates has some tickets for the film.( )
B:He or his classmates have some tickets for the film.(√)
『析』由 or 连接两主语时,谓语动词应与相临近的那一个主语保持一致。故选B。
6.A:Either you or I are on duty.( )
B:Either you or I am on duty.(√)
「析』either...or 连接两个主语时,其谓语动词与相临近的一个主语相呼应,这也叫作就近原 则。类似的用法还有or,neither….nor,not only..but also等。故选 B。
7.A:Mike likes swimming and to collect stamps.( )
B:Mike likes swimming and collecting stamps.(√)
『析』由并列连词连接的两个部分要保持相等的语法结构。如是动名词则都用动名词,如用 不定式则都应用不定式,这是初学者要注意的一点。故选B。
8.A:We will go to both Beijing and Shanghai.(√)
B:We will go both to Beijing and Shanghai.( )
「析』用both…and…作连接词时,其相连接的部分结构也要相同。故选A。
9.A:Not only Mary but also her brothers are going to dance.(√)
B:Not only Mary but also her brothers is going to dance.( )
『析』由 not only...but also…连接两个主语时,其重点在其后面的那一个主语;所以谓语形式 应采用就近原则。故选 A。

二、从属连词
难 点 精 讲
1.宾语从句的从属连词
引导宾语从句的从属连词有连接词、连接代词、连接副词三种。
(1)连接词 that(无词义),只起连接作用,在宾语从句中不充当句子成分,可省略;连接词 if(whether) (是否),只起连接作用,在宾语从句中不充当句子成分,不能省略。
(2)连接代词:who,whom,whose,what,which,连接代词除了起连接主句和从句的作用 外,还在从句中充当主语、宾语、表语或定语。
(3)连接副词:when,where,why,how,连接副词除了起连接主句和从句的作用外,还在 从句中充当状语。
2. 状语从句的从属连词
(1)连接时间状语从句的连词有:when当 … … 时候,after 在 … … 之后,before在 … … 之前, as当 … … ,一边 … … 一边 … … ,as soon as 一 … … 就,while 在 … … 期间,till 直到 … … , since自从。
(2)连接让步状语从句的连词有:although(虽然),though(虽然 ),这两个词是从属连词,而 but是并列连词。因此but不能与although 或 though连用。
(3)连接原因状语从句的连词有:because,since,as
(4)连接条件状语从句的连词有:if(如果)。
(5)连接结果状语从句的连词有:so...that..(如此……以致……),如:
The wind blew so hard that we could hardly walk. 风刮得很大,我们几乎不能走。
(6)连接目的状语从句的连词有:so that 以 便 ,in order that 为了。如:
Please read it louder so that everybody can hear.
请大声点读,以便所有的人都能听见。
She got up early in order that she might be in time for class.
为了能及时去上课,她起得早。

4.He was riding to school he was hit by a car this morning.

8.A:Before I give you the answer,I'll ask you some questions.(√)
B:Before I do not give you the answer,I'll ask you some questions.( )

9.A:While I was walking along the street yesterday,I met an old friend.( )
B:When I was walking along the street yesterday,I met an old friend.(√)

11.A:I have studied English since I was twelve.(√)
B:I have studied English when I was twelve.( )
「 析 ]since引出的时间状语从句是表达了一个时间点,而这个时间点是主句动作的起始点, 所以主句一般要用完成时态。故A 正确。
