定冠词限定名词时主要表示特指,针对TOEFL应注意以下几点:
(1) the和可数名词单数连用,表示一类人或物,如:
the fern(蕨类), the wallflower
(2) 序数词之前必须用the,如:
the first woman, the nineteenth century
但前面有物主代词时除外,如 my first baby
(3) 形容词最高级之前必须用the(有物主代词时除外),如:
the largest city, the most advanced technology
(4) of连接的名词前多用the, 如:
the development of the watch,
(5) 世界上独一无二的东西前应加the, 如:
the globe(地球),the equator(赤道), the moon, the sun
在下列情况下,一般不用the:
(1) 表示人名、地名、国家名等专有名词前, 一般不加,如:
Dennis Chavez(人名),Alaska(地名),English(英语), February(二月),America(美国)
但是在表示海洋、海峡、江、河、山脉、群岛等专有名词时要加上the
the Great Lakes(美国五大湖), the Changjiang River(长江)
(2) 无特指的不可数名词前,如:
algebra(代数学), advertising, accounting(会计学)
(3) 表示类别的复数名词前,如:
Historians believe that…, Amphibians(两栖动物) hatch from…
(4) 一些固定词组中,如:
in history, in nature, at work, at home , go to school, go to bed, in bed
乘车的词组:
by train(乘火车), by car (乘汽车), by bicycle(骑脚踏车),
by bus (乘公共汽车),
by land(由陆路), by sea (由海路), by water (由水路) ,
by air(通过航空)
on foot (步行), by plane(乘飞机), by ship (乘船),
打球的词组:
play tennis, play baseball, play basketball
注意:表示职位的词之前的冠词有无均可, 如:He was elected (the)
chairman of the committee.
不可数名词的限定词和不可数名词原形连用, 下面这些限定词后面一定跟不可数名词:much, a large amount of, a great deal of, a wealth of(大量的、丰富的)little /a little /less /least, a piece /sheet /slice /bar of, 属不可数名词
专用
另外一些词(词组)如such, some /any (of), most (of), a lot of, lots of,the re st of, plenty of等既可接可数名词又可接不可数名词。
有些形容词本身就具有“比….年长”、“ 比…..优越”等含义,因此也就没有比较级和最高级。比如: inferior, superior, senior, anterior。这些形容词往往和to连用,而不和than连用。
有些形容词本身就具备“最、极”的含义,所以就没有最高级和比较级。如:
absolute(绝对的), unique(独一无二的), infinite(无限的), round(圆的), right(对的), correct(正确的), wrong(错误的), perfect(完美的),这类形容词往往被称为绝
对形容词对于most来讲,除了构成某些词最高级外,most的用法有几点需要注意,经常成为改错
题的考点:
1. 当most表示大多数时,之前不加the, 并且有两种形式来表示大多数,分别为:
most + 名词,如:most people, most Indian tribes;
most + of + 限定词 + 名词或代词,如:most of his paintings,most of us, most of the modern artists
2. most有时意思等同于very, 此时most之前用不定冠词,如:
a most lovely girl, a most impressive proposal
例题:
(1)
The most substances expand in volume when they are heated.
A B C D
答案:A
应改为:Most
解释:most只有在表示形容词最高级作定语时需加定冠词,此句表示“大多数”,没必要加the.
Aluminum is the most abundant metal in the crust of the Earth, but the nonme tals
A B C
oxygen and silicon are more still abundant.
D
考点:程度副词
答案:D
应改为:still more
解释:程度副词still修饰比较级more时,应置于其前几点参考规则:
1. 多数副词放在修饰的动词之后,若动词有宾语则放在宾语之后,如:She sings very well.
I met your uncle(动词的宾语) just now.
I met just now your uncle (错)
2. 副词修饰形容词、介词短语、副词时常放在被修饰成分之前,如:
These two are only slightly different.
right after this, very smoothly
当然,副词enough是一个例外,要放在修饰成分的后面,如:
I am not good enough to do this job. (对)
I am not enough good to do this job. (错)
3. 表示频率的副词常放在实意动词之前,be动词之后,如:
He often/ always/ rarely/seldom/never play(实意动词) tennis.
He is always here at 8’clock. (be动词之后)
4. 部分副词的位置没有一定的规定,原则上接近被修饰词即可,如:
only, even, still, perhaps, etc.
