大学英语b级知识点
(一)数词
A. 知识要点
数词分为两大类：基数词和序数词。
1.基数次表示数量(one, two, three„)，序数次表示次序(first, second, third„)。
2.数词hundred, thousand, million不用复数;其“复数+of”可表示数百、数千、数百万，如：three thousand 三千/ thousands of trees(数千棵树)
3.在表达年龄时，注意以下表达法：
He is six years old.(其中year须用其复数)
He is a six-year-old boy.(其中year不用复数)“他6岁了。”
B.例题讲解
1)They have learned about ______ in recent years. (《大学英语》(B)Test 2, 37)
A. several hundreds English words B. hundreds of English words
C. hundred of English words D. several hundred English word
解析：B。hundreds of 之类的短语之前也可加many，several之类的词修饰。A项的错误在于hundreds后缺少of。
2)Nancy is ______ girl. (《大学英语》(B)Test 2, 29)
A. a eighteen-year-old B. an eighteen-years-old
C. a eighteen-years-old D. an eighteen-year-old
解析：D。eighteen-year-old是一个由连字符连接的复合形容词(其中year不用复数)，作girl的定语。同时，由于eighteen是元音开头的词，前面的不定冠词用an。
(二)形容词和副词的原级、比较级与最高级
A. 知识要点
1.比较级和最高级的构成形式
(1)绝大多数单音节和部分双音节词后加-er构成比较级，加-est构成最高级。如： nice – nicer – nicest
(2)大部分双音节词和所有的多音节词，前面加more构成比较级，加the most 构成最高 级。如：careful-more careful-most careful
2.形容词和副词的应用
(1)同等程度比较：
as + 原级 + as e.g. Tom is as bright as Mark.汤姆和亨利一样聪明。
(2)不同程度的比较：
比较级 + than e.g. Tom is taller than Mark.汤姆比亨利高。
not as/so + 原级 + as e.g. Tom is not as/so bright as Mark.汤姆不如亨利聪明。
(3)对比与比较：
the +比较级, the +比较级 e.g. The older I get, the happier I am.我越变老，越觉得幸福。 比较级+ and +比较级 e.g. Jane became more and more beautiful.珍妮越来越漂亮了。
(4)当几个形容词修饰一个名词时，其排列顺序是：
好坏、美丑 + 大小、新旧、颜色 + 质地、属性 + 名词
e.g. a beautiful big blue wooden house
(5)当被修饰的是以-thing, -one, -body结尾的不定代词时，作定语的形容词要后置。 e.g. I read something interesting. 我读了一些有趣的东西。
例题讲解
1)Your box is mine.
A. four times as big as B. four times as bigger as
C. as four times big D. as big as four times
解析：A。在as„as句型中，如有表示程度的状语(如 twice, three times)，则置于第一个as之前，表示前者是后者的几倍。
2)Today’s weather is ______ worse than yesterday’s. (《大学英语》(B)Test 2, 40)
A. very B. much C. very much D. much too
解析：B。very用来修饰形容词的原级形式;much修饰比较级;very much一般用来修饰动词; much too常用来修饰形容词的原级形式。
3)—Did the medicine make you feel better? (《大学英语》(B)Test 6, 43)
—No. The more _______, _______ I feel.
A. medicine I take; and the worse B. medicine I take; the worse
C. I take medicine; the worse D. I take medicine; worse
解析：B。 本题是“越„越„”句型，要用“the + 比较级，the + 比较级”句型，前后分句都用陈述语气。
4)—What will you buy for your boyfriend’s birthday? (《大学英语》(B)Test 5, 34) —I want to buy a _______ wallet for him.
A. black leather small B. small black leather
C. small leather black D. black small leather
