Question

18．Bell invented the telephone by trying manytimes（time）and learning from his mistakes．

Answer 1

分析 貝爾通過嘗試很多次并從錯(cuò)誤中學(xué)習(xí)，發(fā)明了電話．

解答 答案：times
聯(lián)系語境，根據(jù)關(guān)鍵詞many可知其后應(yīng)該跟可數(shù)名詞的復(fù)數(shù)形式；結(jié)合提示詞time在此句的意思為"次數(shù)"，為可數(shù)名詞，所以空處應(yīng)該用其復(fù)數(shù)形式times，many times指許多次，這里是指貝爾在發(fā)明電話的過程中嘗試了很多次．故填：times

點(diǎn)評(píng) 此題考查名詞的單復(fù)數(shù)的變化．做題時(shí)根據(jù)關(guān)鍵詞的提示結(jié)合句意確定出名詞的單復(fù)數(shù)做出相應(yīng)的變化即可．
