(3)probable 的可能性比possible 大，表示“很可能，十有八九”，通常用于it is probable that ...句型。

★41.(XX年高考陜西卷)studies show that people are more ________ to suffer from back problems if they always sit before computer screens for long hours.
a.likely b.possible
c.probable d.sure
解析：選a。研究表明，如果人們總是長時間地坐在電腦屏幕前面，他們的背部更有可能會出問題。四個選項(xiàng)中主語為人且和不定式連用的只有l(wèi)ikely和sure，likely表示“有可能的”，sure表示“必定，肯定”，根據(jù)句意應(yīng)用likely。possible作表語時主語不能為人；probable的主語只能是物。

倒裝句和強(qiáng)調(diào)句
倒裝是一種語法手段，用于表示一定的句子結(jié)構(gòu)或強(qiáng)調(diào)某一句子成分。倒裝句有兩種：完全倒裝和部分倒裝。
完全倒裝即把整個謂語放到主語之前(是整個謂語動詞，而非助動詞)。
【佳句選粹】
in came the teacher and the class began.
【分析】 句意：老師走了進(jìn)來，然后開始上課。in放于句首，整個句子用了全部倒裝的形式，came放到了the teacher之前。
部分倒裝即只把謂語的一部分(如助動詞、情態(tài)動詞等)放到主語前，或把句子的強(qiáng)調(diào)成分提前。
【佳句選粹】
were she to leave right now，she would get there on sunday.
【分析】 句意：如果她立刻就走，她就能在星期天到達(dá)那里。此句前半部分省去了if，把were提前。
