certainly 是來(lái)修飾后面的 the most beautiful one 的.be是系動(dòng)詞,后面跟形容詞,如果跟副詞,副詞是修飾后面的形容詞,動(dòng)詞之類(lèi)的.
He is really happy.really來(lái)修飾happy He is always helping others.always修飾helping了解，很感謝。很貪心地再問(wèn)一個(gè)問(wèn)題…一道選擇題：Which is _____ to learn,swimming or fishing?A.easy B.more easily C.the easier...我覺(jué)得是選C但是同學(xué)說(shuō)選B，雖然不清楚C里為什么比較級(jí)前加了the，但是我覺(jué)得不應(yīng)該用副詞啊。to learn是一個(gè)動(dòng)詞不定式吧？副詞可以修飾動(dòng)詞不定式？并且不是有個(gè)句型是it is adj. to do sth嗎。。還是關(guān)于be動(dòng)詞和副詞的問(wèn)題，呵呵。。我覺(jué)得哪個(gè)都不對(duì)， 應(yīng)用 easier ，be+形容詞，如果有of the two, 就用the +比較級(jí)例如：This ruler is the shorter of the two.這句話如果是 Which is the easier to learn of the two, ...? 就選C。但是這句話這么問(wèn)，有點(diǎn)別扭。老師也是這么說(shuō)的，要加of the two，但是總該不會(huì)用副詞吧，哈哈！非常謝謝你哦~
