Question

20．a(chǎn)re good for，fruits and vegetables，to keep fit，people，fresh（連詞成句）
Fresh fruits and vegetables are good for people to keep fit．

Answer 1

分析 新鮮水果和蔬菜對人們保持健康是有好處的．

解答 答案：Fresh fruits and vegetables are good for people to keep fit．
通過觀察所給的單詞和短語，根據(jù)are good for，to keep fit，people可聯(lián)想到句型：主語+be good for sb to do sth意為"某事對某人做某事有好處"，結(jié)合該結(jié)構(gòu)可知所給的名詞短語fruits and vegetables在句中作主語，其中形容詞fresh可作定語修飾該短語，即主語為Fresh fruits and vegetables，people跟在介詞for后面，套用結(jié)構(gòu)，故答案為Fresh fruits and vegetables are good for people to keep fit．

點評 瀏覽所給單詞聯(lián)想到所學(xué)句型，所以平時還是要多記憶一些固定句型．
