《现代汉语》Ⅱ练习（2）答案《现代汉语》Ⅱ练习（⼆）[词类和短语]年级专业班级姓名学号⼀、名词解释1.词类：词类是词的语法分类。
划分词类的标准，是词在语法上的区别性特征。
词在语法上的区别性特征，简称词的语法特征，主要表现在以下三个⽅⾯：第⼀，词的语法形式；第⼆，词的组合能⼒；第三，词的造句功⽤。
2.充⾜性语法特征：所谓充⾜性语法特征，指的是可以成为充⾜条件的语法特征。
判定词性时，作为判定词性时的充⾜性语法特征要有明确的限定。
限定的形式是：“主体条件＋附加条件”。
3.同形异类：所谓同形异类，是指词的形式相同，但实际上属于不同的词类，在甲语法环境中是甲类，在⼄语法环境中是⼄类。
同形异类现象也叫兼类现象。
4.短语：由两个或两个以上的词按着⼀定的结构关系组合⽽成的⽐词⾼⼀级的语⾔单位，叫作短语。
短语有固定短语和⾃有短语的区别。
固定短语具有结构的凝固性和意义的整体性。
5.兼语短语：组成部分之间有连环套合的兼语关系，由前⼀动词的宾语兼做后⼀动词或形容词的主语，即动宾短语的宾语和主谓短语的主语套叠，形成⼀个宾语兼主语的兼语。
这样的短语就是兼语短语。
6.多层次复杂短语：由两个以上的词按着⼀定的结构关系组合⽽成、包含两个或两个以上层次的短语，叫作多层次短语。
多层次复杂短语是简单短语通过延伸、加合、交互、连环四种延展⽅法扩充⽽成。
⼆、简述题1.什么是词的语法特征？举例说明词的语法主要表现在哪些⽅⾯。
词类是词的语法分类。
划分词类的标准，是词在语法上的区别性特征。
词在语法上的区别性特征，简称词的语法特征，主要表现在以下三个⽅⾯：第⼀，词的语法形式。
指具备什么样的形式标记和变化⽅式。
有的语⾔可以借助于词的形态变化来划分词类。
例如英语：A 名词[单数、复数] B形容词[原级、⽐较级、最⾼级] C 动词[原形、过去式、过去分词、现在分词]horse（马）→horses high（⾼）→higher\highest deny（否认）→denied\denyinghat（帽⼦）→hats big（⼤）→bigger\biggest collect（收集）→collected\collectingtree（树）→trees old（⽼，旧）→older\oldest remember（记得）→remembered\remembering 第⼆，词的组合能⼒。

阅读理解练习（2）Passage 4:One way that scientists learn man is by studying animals, such as mice and monkeys. The scientists in this laboratory are experimenting on mice. They are studying the relationship between diet and health. At this time, over one hundred experiments are being done in this laboratory.In one of these experiments , the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running , playing with one another, and using the equipment in their cages. Also , they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years.The second group of mice is normal weight. They are healthy, too . They are active , but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought----about a year and a half. But they aren’t as healthy. They’re sick more often than the other two groups.11.The scientists in the laboratory are studying the relationship between＿＿＿.A. mice and dieB. the amount of the food the mice eat and their health.C. the amount of food and diet.D. mice and men12. ＿＿＿ receiving the most food.A.
