Answer 1

【答案】
（1）cut down
（2）made a difference
（3）had heard of
（4）is harmful to
（5）is good for
【解析】（1）句意是：上學(xué)期學(xué)生們通過(guò)步行上學(xué)來(lái)減少空氣污染。根據(jù)句意選擇短語(yǔ) cut down，時(shí)間是 last term，動(dòng)詞用過(guò)去式，cut 過(guò)去式和原形一致，故填 cut down。
（2）句意是：你的幫助發(fā)揮作用了，現(xiàn)在我對(duì)這工作更了解了。根據(jù)句意選擇短語(yǔ) make a difference，根據(jù)句意 has 是現(xiàn)在完成時(shí)的助動(dòng)詞，后面跟過(guò)去分詞 made，故填 made a difference。
（3）句意是：在國(guó)王看見之前這個(gè)王國(guó)的所有的人都聽說(shuō)過(guò)這種神奇的布。hear of 聽說(shuō)，“所有人聽說(shuō)”這一動(dòng)作發(fā)生在“國(guó)王看見之前”，表示“過(guò)去的過(guò)去”，用過(guò)去完成時(shí)，故填 had heard of。
（4）根據(jù)句意“污染對(duì)我們的健康有害”可知選擇短語(yǔ) be harmful to，主語(yǔ) Pollution是不可數(shù)名詞，故動(dòng)詞用 is，填 is harmful to。
（5）句意是：“這食物對(duì)你有益，盡管它嘗起來(lái)味道不好�！蔽覌寢寣�(duì)我說(shuō)。根據(jù)句意選擇短語(yǔ) be good for，主語(yǔ)是 the food ，故動(dòng)詞用 is。
