高考考点分析

问题1：

When and where to build the new factory ____ yet. （1991 NMET）

A. is not decided B. are not decided

C. has not decided D. have not decided

这个句子看上去是and连接的两个并列短语充当主语，本应用复数形式的谓语，但这两个短语表达的是同一事件的两个方面，可以看成是一个整体，因此使用单数的谓语动词；而从句意可判断此句谓语动词需使用被动语态，

?

归纳一：

1．两个或两个以上做主语的单数名词用and或both ….and连接时，谓语用复数．

Tom and Dick are good friends.

Both rice and wheat are grown in China.

To play football and to go swimming are useful for character training.

注意:当and不表示并列意义,而是连接两个意义上表示同一人,同一物或同一概念;或由两个部件构成的物品时,谓语动词用单数.

A singer and dancer was present at the party.

The worker and writer is talking to the students。

Bread and butter tastes good.

类似的表达式有：

( a needle and thread, a knife and fork,a cup and saucer ,a horse and cart, a watch and chain, salt and water, truth and honesty, medical help and cure,iron and steel,war and peace,cause and effect,supply and demand,pen and ink,early to bed and early to rise ,to love and to be loved)

Eg:War and peace is a constant theme in history.

To love and to be loved is great.

2．由no, each, every, many a ,more than one等修饰的主语或两个并列的名词主语,谓语动词用单数。
