Answer 1

小題1:importance
小題2:actively
小題3:unnecessary
小題4:culrural
小題5:thirty-third

小題1:考查詞性轉(zhuǎn)換。句意“校長(zhǎng)昨天給我們做了演講，是關(guān)于保護(hù)環(huán)境的重要性的�！睉�(yīng)該用important的名詞形式，故填importance。
小題2:考查副詞。修飾動(dòng)詞用副詞，actively積極地，故填actively。
小題3:考查形容詞的否定形式。他不和我們一起去，沒必要告訴他旅行的詳細(xì)內(nèi)容。故填unnecessary。
小題4:考查詞性轉(zhuǎn)換。culture的形容詞是cultural，作定語(yǔ)修飾differences。故填cultural。
小題5:考查序數(shù)詞。第三十三即thirty-third。故填thirty-third。
