解答 【答案】
61.Since.考查连词.本句表示"自从他大学毕业以后",所以用Since表示"自从".
62.finding.考查非谓语动词.given his life to用现在分词finding做宾语,表示"献身于".
63.a.考查冠词.修饰单数名词problem,表示"一个问题",用a.
64.for.考查介词.固定短语search for表示"搜索".
65.however.考查连词.本句表示"去年产量是两百万吨",和他 的预期是转折关系,所以用however连接.66.was produced.考查被动语态. rice和produce之间是被动关系,而且时间状语是Last year,所以谓语动词用一般过去时态的被动was produced.
67.world's.考查名词所有格.做名词people的定语用名词所有格world's.
68.to increase.考查非谓语动词.increase their rice harvests是目的状语,所以用动词不定式to increase.
69.hunger.考查派生词.rid the world of 表示"是世界摆脱饥饿",所以介词的宾语用名词hunger.
70.larger.考查形容词的比较级.根据 than before可知用比较级larger.
点评 考查语法填空.
语法填空的解题技巧
语法填空是通过语篇在语境中考查语法知识的运用能力.我们在解题前应快速浏览短文掌握大意,有把握的空格可以进行填写.在读懂的基础上,再结合短文提供的特定的语言环境去逐句分析逐题解答.按题型设计分三种情况:
1.纯空格试题的解题技巧
首先分析句子结构,根据所缺成分确定哪类词.然后,根据句子意思,确定具体填什么词,或根据两句间的逻辑关系确定具体用哪个连词.比如第65小题,考查连词.根据前后文的关系可得出,此处为转折关系,故填however.
2.给出了动词的试题解题技巧
首先,判断要填的动词是谓语动词还是非谓语动词.若句子没有别的谓语动词或者虽然已有谓语动词,但需填的动词与之是并列关系,所给动词就是谓语动词,若是谓语动词就要考虑时态和语态;若句子有谓语动词则用非谓语动词(动词不定式、现在分词、动名词和过去分词).比如第68小题,考查固定用法.此处to do表示目的,故填to increase.
