解答 61.natural;考查形容词用法.此处用形容词形式在名词colors前作定语.
62.eating;考查固定搭配.enjoy doing sth是固定用法,意为"喜欢做某事".
63.is;考查主谓一致,句子的主语Each color为单数形式,故谓语动词也要用单数形式,这里用is与后面的important构成系表结构.
64.our;考查物主代词.本句中we是主格,在句中做主语,而在名词前要用形容词性物主代词做定语.所以本句中使用our修饰名词bodies.
65.the;考查定冠词.本句中形容词good和定冠词the连用指一类事物,同时表示特指,而且the good的后面还有介词短语of colorful fruits and vegetables修饰,所以用the表示特指.
66.possibly;考查副词.本句中使用副词possibly做状语修饰动词reduce.
67.for;考查介词固定搭配.固定短语be good for意为"对…有益健康的"..
68.teeth;考查名词复数形式.因tooth是可数名词,且要与and前面的bones并列,故用复数形式..
69.when/while/if;考查句式结构关系,结合上下文分析,本句可理解为"如果/当你卖蔬菜水果的时候…",所以此处可以用if引导一个条件状语从句,或用when/while引导一个时间状语从句.
70.to try;考查固定结构.动词短语remember to do记住要做…,表示去做未做的事情.而remember doing sth.记得做过某事,使用动名词doing表示已经做过的事情.
