参考答案与解析
1. B 解析:考查分数的用法。分数的表达方式是,分子用基数词,分母用序数词。分子超过2时,分母要复数形式。故选B。
2. D 解析:考查数词、名词和代词的用法。“再需要两个小时”,应该用“need another+数词+复数名词”结构。“It takes sb. some time(花费某人一段时间)”是固定句型。故选D。
3. D 解析:考查交际应答。疑问句是询问对方什么时候进行校际旅游的,应答句应该用表示过去的时间状语,不是“五天以后”、“五天”或“一天两次”。故选D。
4. C 解析:考查复合形容词的用法。five-year-old 这类复合词可以用作形容词,意为“五岁的”,并且其中表示计量的名词(如year,month等)总是用单数形式。这类结构通常用作前置定语,不用作表语(作表语时可改用seven years old这样的形式),排除B项。又因为five years old在句中作表语,也排除,修饰boy只能用five-year-old。故选C。
5. A 解析:考查时间的读法。按英语的习惯,顺读法表示时间直接说即可,six ten符合题意要求。其他三项均不合乎题意,应该排除。故正确答案选A。
6. A 解析:考查分数的表达。英语分数词常用基数词作分子,用序数词作分母。分子超过一时,分母用复数形式。故选A。
7. B 解析:考查数词的用法。hundred 与具体数字连用时,用单数。分数表达法:在表达分数时,分子用基数词,分母用序数词,分子大于一时,分母用复数。故选B。
8. B 解析:考查分数及主谓一致的用法。句意:地球将近四分之三被海洋所覆盖。表示分数时,按英语的习惯,分子大于“1”,分母加“s”。另外,主语指的是一部分,看作一个整体,因此谓语动词应该用单数。符合句意要求的应该是B,其他三项均不合题意,应该排除。故选B。
