Now more than 60% of the rice____3____(produce) in China each year is from this hybrid strain.
【答案】1. graduated
2. who/that
3. produced
【解析】
【分析】
这是一篇说明文。文章主要介绍了袁隆平对于中国农业的杰出贡献—高产杂交水稻的研究。
【1题详解】
考查时态。句意:袁隆平1930年出生,1953年毕业于西南农学院。分析可知,所填空应是句中谓语,结合时间状语“in 1953”,应是一般过去时。故填graduated。
【2题详解】
考查定语从句。句意:1973年,他成为世界上第一个种植高产水稻的农业先驱。分析可知,“__2___grew rice with a high output”应是之前名词“the first agricultural pioneer”的定语从句,先行词在从句中作主语,应用关系代词who/that引导。故填who/that。
【3题详解】
考查非谓语。句意:现在中国每年60%以上的水稻都是这种杂交品种。分析可知,“____3____(produce) in China each year”应是之前名词短语“more than 60% of the rice”的后置定语,动词与其之间为被动关系,应用过去分词形式。故填produced。
【点睛】语法填空题之非谓语 判断
当所给动词为动词时,除了考虑填写谓语,还要考虑是否为非谓语。这时,句中已经存在谓语,所填动词考虑作定语和状语成分居多,下一步确定为主动关系还是被动关系,即选择现在分词形式还是过去分词形式。比如文章第3小题:
Now more than 60% of the rice ____3____ (produce) in China each year is from this hybrid strain.
分析可知,句中已经存在谓语is, 提供动词produce在名词之后,作后置定语,且为被动关系,应用过去分词做后置定语,故答案为produced。
