答案解析
文章大意
本文讨论的是肯尼亚旱情及救援状况。肯尼亚的北部正遭受着严重的旱灾侵袭，伤亡随处可见，牲畜日渐消瘦，还有尸体堆积在学校附近。从年初开始，学校学生的出勤率就开始严重下滑，很多家庭都离开了干旱的家园，有些家庭甚至进入战火连连的索马里去寻求食物。肯尼亚旱灾已经持续了一年，但直到今年夏天旱情最严重的时候，新闻媒体和国际捐助才开始给予关注。如果救援及早介入，情况可能就不会如此糟糕了。
答案详解
1．is→are语法错误。livestock(牲畜，家畜)是一个集合名词，形式上是单数，但却表示复数意义，所以此处谓语动词应该用复数。
2．at→since词汇错误。该句使用了完成时态，完成时态通常与since等引导的表示“一段时间”的状语连用，而不与某一时间点连用，所以用since替换at。
3．with→with词汇错误。leave与with连用时，通常用在leave...with...或者be left with...结构中，表示“把……留给……（照料或处理）”，此处无论是用主动结构还是被动结构，都解释不通，此句要表达的意思是 “很多家庭都带着羊群离开这个干旱的地区”，所以要删掉with，leave后直接接地方，表“离开某处”。
4．∧some→and或crossed→crossing语法错误。此行中前后两句都是完整、独立的句子且动词都是谓语动词形式，所以不能仅仅用逗号连接。可以用连词and连接，或者将crossed改为crossing，使后句中的动词变成非谓语动词形式，成为独立主格结构作状语。
5．comes→come语法错误。此句是倒装句，come的主语是the news media pictures of emaciated infants,是一个复数概念的短语，所以动词也要用复数形式。
6．visitors→visits词汇错误。从上下文来看，此处要表达的意思是“政府高层官员的来访”，而不是“来自政府高层官员的访客”，而且从句子结构来看，followed by后接的并列宾语均指物，这包括conferences和commitments，所以此处也应该用一个指物的宾语，故把visitors改为visits.
7．rises→raises词汇错误。rise是不及物动词，表示“升起，上涨”；raise是及物动词，有“提出，引起”的意思，用在此处意为“提出质疑，引起质疑”。
8．like→unlike语篇错误。原句在意义上不符合逻辑，地震和飓风并不像旱灾和食物价格上涨一样是逐渐发展的灾难，它们是突发性的，前后并不是同类列举，所以此处应该用表示否定意义的词unlike。
9．harvest→harvesting词汇错误。harvest作名词时表示“收获，产量，结果”，用在此处解释不通，harvest用作动词时，可表示“获得”的意思，用在此处意为“获得水资源”，所以此处应该用其动名词形式。
10．∧have→could语法错误。从后面的反问句可以推断那些缓解灾难的措施并没有被采用，所以此处应使用虚拟语气，表达一种遗憾的语气：我们本来可以采取一些措施来缓解目前的灾难。用could+have done来表示“本来可以做而没做……”。
