Had he studied harder, he_______ the exams.A.must have got through B.could get throughC.would get through D.would have got through【答案】D【解析】試題分析:句意:如果他學(xué)習(xí)再努力一點,他就能通過考試了。must have got through 一定通過;could get through 可能通過;would get through 會通過;would have got through 會通過。這句話中Had he studied 是一種省略倒裝的形式,相當(dāng)于If he had studied harder,是虛擬語氣的用法,從句中用的是過去完成時,這時主句用would +have +過去分詞。故選D。考點:考查虛擬語氣。27.If I a bird, I _ fly in the blue sky.A.was。 would B.a(chǎn)m。 will C.will be。 will D.were。 would【答案】D【解析】試題分析:句意:如果我是一只鳥,我就能在藍色的天空中飛翔。根據(jù)句意可知,這里表示的是跟事實不符的情況,是不可能實現(xiàn)的事情,因此這里應(yīng)該用虛擬語氣。在if從句中用一般過去時,主句中用would+動詞的原形。故選D??键c:考查虛擬語氣。28.—Swimming in the river for teenagers is very dangerous.—So it is. If I ________ them, I ________ a shower at home.A.a(chǎn)m。 would take B.were。 will takeC.was。 would take D.were。 would take【答案】D【解析】試題分析:—在河里游泳對青少年是非常危險的。—的確如此。如果我是他們,我會在家洗澡。if從句表假設(shè),與現(xiàn)在事實相反,be動詞則用were ,無論第幾人稱做主語。主句常用would 跟動詞原形。故選D??键c:考查固定句式的用法。29.What would you do if you _____ the traffic accident?I would ______.A.see,do my housework first B.saw。buy some fruit right awayC.see。call at 110 at once D.saw。call the police right away【答案】D【解析】考查虛擬語氣和情境交際的用法。問句使用了虛擬語氣,從句中應(yīng)使用一般過去時;根據(jù)traffic accident,應(yīng)及時報警。30.If I______you, I_______go there at once.A.a(chǎn)m, would B.were, would C.were, will D.a(chǎn)m, will【答案】B【解析】試題分析:句意:如果我是你,我會馬上去那里。句子用到了虛擬語氣,系動詞be要用were;will要用過去式would,結(jié)合題意故選B??键c:考查虛擬語氣。
