誘思:實例點撥
【例1】 (浙江模擬) the old tower must be saved, ________ the cost.
a.however b.whatever c.whichever d.wherever
提示:考查連詞及省略句，補全句子應為 “the cost is”，從結構看選項作表語，而however多用來加強程度，后接形容詞或副詞。故選b。
答案:b
【例2】 (江西模擬) cars do cause us some healthy problems—in fact far more serious ________ than mobile phones do.
a.one b.ones c.it d.those
提示:替代上文出現的同類事物中的一個用one，復數用ones；而it與that都表示特指，所以不要誤選that的復數those。故選b。
答案:b
講評:解考查指示代詞it，one和that的題時，要牢記one為泛指同類，而it和that表示特指。
