1.has grown 句意为：自从2011年以来，中国种植的玉米已经比水稻多了。

动词grow之间为主动关系，应用主动语态，故填has grown。
2.the 句意为：在过去的25年中，玉米的产量猛增了将近
125%，而水稻产量只增加了7%。此处特指“过去25年”，
故填the。
答案及解析

种影响和结果。常被just，already，yet等副词修饰。(2)现在完成时表示从过去

during/over/in the past/last＋一段时间；so far/up to now/up till now等。(3)现在完
成时表示说话前发生过一次或多次的动作，现在成为一种经验，一般汉语译为
“过”，常与twice，ever，never，three times等时间状语连用。

和水库的水污染，使得饮用水对于人们来说更加安全。此
处作has decreased的宾语，应用名词形式，表示“污染”，

9.that/which 句意见上一题解析。分析句子结构可知，此
处为定语从句，修饰先行词a soiltesting programme；空格
处为定语从句引导词，从句中缺少主语，且指物，故用that
或which引导定语从句。
10.feeding 分析句子结构可知，feed与其逻辑主语China
之间为主动关系，故用动词的现在分词形式。
7.global 句意为：世界银行的数据显示，中国的化肥消耗
量约占全球化肥消耗总量的30%。此处修饰名词短语
fertilizer consumption，应用globe的形容词形式，故填global。

interesting→interested

earlier→early
that→which
a→an/one
删除for Beside→Besides
came→comes
informations→information
在pick前加to
答案及解析
第一处：all→both或删除all 这里是指张先生和张太太两个人都在“我们”学校工作。表示“两
者都”应用both，而all表示“三者或三者以上都”，不符合语境；此处删除all意义也完整。
第二处：a→an/one 这里表示“一个半小时”，所以应用不定冠词或者数词one修饰hour，又因
hour以元音音素开头，所以其前应用不定冠词an修饰。故将a改为an或one。
【方法总结】冠词的基本用法
a用在以辅音音素开头的单词前，如：a man一个男人，a university一所大学，a European一个欧洲
人，a oneway street单行道；an用在以元音音素开头的单词前，如：an apple一个苹果，an island一
个岛，an uncle一位大叔，an onion一个洋葱，an egg一个鸡蛋，an honest boy 一个诚实的男孩。
第三处：interesting→interested be interested in… 为固定搭配，意为“对……感兴趣”。故将
interesting改为interested。
第四处：that→which 分析句子结构可知，此处引导非限制性定语从句，修饰先行词garden，指物，
关系词在定语从句中作主语，that不能引导非限制性定语从句，所以应用which。
第五处：earlier→early 句意为：他们经常早起，并一起给蔬菜浇水。根据语境可知，此处讲述

第六处：删除for 动词buy 是及物动词，其后直接加宾语。故删除for。
第七处：Beside→Besides beside为介词，意为“在……旁边”；besides为副词，意为“除
此之外”。该处后有逗号，根据语境可知此处应用副词Besides。故将Beside改为Besides。
第八处：informations→information information为不可数名词，没有复数形式。故将
informations改为information。
第九处：came→comes 本句主句为一般将来时，表示将来的动作，从句为When引导的时
间状语从句，此处符合“主将从现”原则，因此，从句应用一般现在时表将来。故将came
改为comes。
【知识拓展】“主将从现”原则
在由when, while, before, after, until, as soon as等引导的时间状语从句或由if, unless引导的
条件状语从句以及让步状语从句中，如果主句表将来的动作或状态(可以用一般将来时，也
可以是祈使句或“情态动词＋动词原形”)，从句用现在时(可以是一般现在时、现在进行时
或现在完成时)表示将来动作。
第十处：在pick前加to invite sb to do sth意为“邀请某人做某事”，为固定搭配。故在pick
前加to。
