一、用單詞的適當(dāng)形式完成句子
1.All the (legal) constructed buildings must be pulled down. (所給詞的適當(dāng)形式填空)
【答案】illegally
【詳解】考查副詞。句意:所有違章建筑都必須拆除。空處修飾constructed,需用副詞作狀語,表示“違法地”應(yīng)用illegally。故填illegally。
2.We have reached a stage where we must start taking (effect) measures to protect the environment so as to save ourselves. (所給詞的適當(dāng)形式填空)
【答案】effective
【詳解】考查形容詞。句意:我們已經(jīng)到了必須開始采取有效措施保護環(huán)境以拯救我們自己的階段?崭裉幱眯稳菰~作定語,修飾名詞measures,effect的形容詞是effective,意為“有效的”,故填effective。
