2016年公共英语考试pets2口语语法精讲五
副词、形容词
1.形容词及其用法
1)表语形容词只能作表语,这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid,afraid,alike,alive,alone,asleep,awake等。
2)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后。例如:something nice.
2.以-ly结尾的形容词
大部分形容词加-ly可构成副词。但friendly,deadly,lovely,lonely,likely,lively,ugly,brotherly,仍为形容词。
3.用形容词表示类别和整体
1)某些形容词加上定冠词可以泛指一类人,与谓语动词的复数连接,如the dead,the living,the rich,the poor,the blind,the hungry等。例如:
The poor are losing hope. 穷人行将失去希望。
2)有关国家和民族的形容词加上定冠词指这个民族的整体,与动词的复数连用,如the British,the English,the French,the Chinese等。例如:
The English have wonderful sense of humor. 英国人颇有幽默感。
4.形容词与副词的比较级
常见的双音节或多音节词,在前面加more,most来构成比较级和最高级important/ easily more important/ more easily most important/ most easily
5.as + 形容词或副词原级+ as
1)在否定句或疑问句中可用so… as.例如:
He cannot run so/as fast as you. 他没你跑得快。
2)用表示倍数的词或其他程度副词做修饰语时,放在as的前面。例如:
This room is twice as big as that one. 这房间的面积是那间的两倍。
Your room is the same size as mine. 你的房间和我的一样大。
3)倍数+ as + adj. + as 倍数+ the … + of.例如:
This bridge is three times as long as that one. 这座桥的长度是那座的三倍。
This bridge is three times the length of that one.
Your room is twice as large as mine. 你的房间是我的两倍大。
Your room is twice the size of mine.
6.可修饰比较级的词常用的有a little,rather,much,far,many,等Nanjing is a little/rather/much/far/ hotter than Shanghai.如果后接名词时,much more +不可数名词,many more +可数名词复数。
I have many more books than Tom.
There is much more water in the south than in the north.
7. the + 最高级+ 比较范围
1)形容词最高级前通常必须用定冠词the,副词最高级前可不用。例如:
The Sahara is the biggest desert in the world. 撒哈拉沙漠是世界上最大的沙漠。
形容词most前面没有the,不表示最高级的含义,只表示“非常”。例如:
It is a most important problem. =It is a very important problem. 这是个很重要的问题。
2)by far一般修饰最高级,
This question is by far the most difficult in this exercise. 这道题是这个练习里最难的。
注意:最高级的意义有时可以用比较级表示出来。例如:
Mike is the most intelligent in his class. 马克是班上最聪明的。
Mike is more intelligent than any other students in his class. 马克是班上最聪明的。
8. 和more有关的词组
the more…the more… 越……越……。例如:
The harder you work,the greater progress you’ll make. 越努力,进步越大。
