/ No, you needn’t.2.當must表示較為肯定的推測“一定”時,變?yōu)榉穸ň鋾r,應(yīng)變?yōu)椤癱an’t”。3.用may提問的一般疑問句,肯定回答用may。 否定回答常用mustn’t 或can’t,很少用may not。如: May I put my bike here?

(2003 寧夏) A. are B. is C. were D. was正解:選 D解析:答案 A B 時態(tài)應(yīng)用一般過去時。時態(tài)不符。答案 C 主語為everyone, 應(yīng)看作第三人稱單數(shù),謂語應(yīng)用單數(shù)形式。二、 考點點撥:1.不定代詞作主語要看作第三人稱單數(shù),謂語動詞通常用單數(shù)形式。2.主語后跟有with, but, except, like, as well as, 等詞引導(dǎo)的短語作定語時,謂語只看其前面的,不要受這些介詞短語的影響。如:The girl with her mother is going to visit the big city next week.專家提示:英語學(xué)習(xí)中應(yīng)注意主語謂語在人稱和數(shù)的一致問題。1. 就近原則。常用就近原則的結(jié)構(gòu)有:① there be 句型。② either…or…(或者…或者…)。③ neither…nor…(既不…也不…)。④ not only…but also…(不僅…而且…)。 謂語動詞的單復(fù)數(shù)形式由距離謂語動詞最近的主語部分決定。如:There is a book and some pens on the desk.Neither you nor she likes playing basketball.2. 意義一致① class, family等部分集體名詞作主語時,如強調(diào)整體,謂語用單數(shù);如強調(diào)個體成員時,謂語用復(fù)數(shù)。如:My family has moved to the small town.My family often watch TV after supper.② 表示“總和”的時間、距離、金錢、重量等的復(fù)數(shù)名詞作主語時,謂語動詞用單數(shù)。如:22,000 dollars is a lot of money.③ 分數(shù)或百分數(shù)作主語時,謂語動詞的數(shù)由分數(shù)后的名詞的形式來確定。如:Two thirds of the apples are mine. Two thirds of the apple is bad.Two thirds of the water is used to water the tree.④ 非謂語動詞結(jié)構(gòu)或從句作主語時,謂語一般用單數(shù)形式。如:Reading in bed is bad for our eyes.6
