In the 1970s数词专项练习题(答案)1.B2.D3.B4.A5C【解析】试题分析:在英语中,当数次表示具体数字时,用单数形式。在读超过一百的数字时,习惯读法是在百位和十位之间用介词 and 相连,其它数位一次读出各级数位即可,选项 ABD 读法有误,故选 C。考点:英语中数字的读法点评:英语中数词的应用有一些不同于汉语的规则,学习中应注意总结记忆。6.C7.B8.A 。two and a half years 也可说成two years and a half,意思都是“两年半”。word 可编辑资料收集于网

23、络,如有侵权请联系网站删除9.B10.B11.B12.D13B 【解析】试题分析:“数字-名词 -形容词”的结构表示的是符合形容词,一般作定语。在这种结构中应注意两点:一是用连字符,二是名词必须用单数。而“数字+名词(复数) +形容词”的结构,一般做作表语。根据本题中的两个空的位置可知,第一个是作表语,而第二个是作定语。所以本题选B 。考点:本题考查固定用法点评:做本题时,比较容易选错,许多学生不知什么时候用作定语,什么时候用作表语;有时有的学生还加以混用。所以对此应该准确掌握。14.D15B 【解析】分数表示法为:分子用基数词,分母用序数词,分子大于1, 分母加 s,在分子与分母之间可加连字

24、符也可不加连字符,所以2/3 表示为 two-thirds 或 two thirds ;分数在句中作主语时谓语和它修饰或指代的名词保持一致。本题中two-thirds 指代 coats, 所以谓语用复数形式are。故选 B。考点:分数表达及主谓一致16C【解析】试题分析:根据题干,第一个空是分数。在英语中表示分数时,分子用基数词,分母用序数词,分子超过一的,分母要加s,故用排除AB ;根据本句的主语the land 可知,此处应该用is。所以本题选C。考点:本题考查分数点评:题需要熟练掌握分数的表达方法;另外,第二个空前面题干比较长,需要认真分析本句的主语是什么,这是较难的。17B 【解析】试

25、题分析:英语中一般用基数词表示分数的分子,用序数词表示分数的分母。当分子是一时,分数的分母用单数形式,在表示分数时,当分数的分子大于一时,分数的分母要用复数形式。句意:地板的四分之三都湿了。有分数修饰的名词的单复数,与被修饰的名词保持一致, floor 作为地板讲时,是不可数名词。故谓语动词用单数,选 B。考点:分数表达点评:英语分数的表达规则比较固定,学习中应牢记这些基本规则。需注意的是,由分数修饰的主语后面谓语动词的数,和被修饰主语的单复数保持一致。18D【解析】试题分析:句意:在我的公司每天大约有九分之二的员工开车上班。workers,为复数形式,谓语动词用复数形式,故选Dtwo-ninths 九分之二,为固定表达,本句中主语为考点:分数的表达点评:英语中分数的表达,分子用基数词,分母用序数词,当分子大于1 时,分母用序数词的复数形式,这个基础知识要求学生进行掌握,此外对于分数的表达所指代的名词如果为复
