5.　　 C whichever已失去疑問含義，等于 anything that，表示強(qiáng)調(diào)； 而 which topic中 which保留疑問含義，譯成“哪一個(gè)題目”，不符合句義。而A和D中缺少連詞。

4.　　 D 如將A項(xiàng)中was ,since改成is, since是正確的；即從句中謂語先發(fā)生。如用B項(xiàng)，是強(qiáng)調(diào)句，而強(qiáng)調(diào)句前后兩個(gè)謂語動(dòng)詞在時(shí)間上必須一致(a)；被強(qiáng)調(diào)部分能還回原句中(b)，即因?yàn)榫渲衱as declared是過去時(shí), B項(xiàng)中is改成was；因?yàn)榫渲衱as declared是非延續(xù)性動(dòng)詞，在years后加上ago將“一段” 時(shí)間變成“一點(diǎn)”就是正確的。C 項(xiàng)前后時(shí)間不一致。

3.　　 B 抽象名詞不特指時(shí)，前不用冠詞。

2.　　 B success 名詞，保留遠(yuǎn)動(dòng)詞含義“成功”是不可數(shù)名詞；如用來代替具體的人(成功者)或具體的事(成功的事情(東西))是可數(shù)名詞。故排除C,D；A中how是副詞，如改成how great a success就是正確的。
