2019/07/16
很多AEIS考生一直不清楚自己的作文得分为什么提不上去,明明表述内容和文章结构都已经有很不错的水准,成绩却还是无法保证。这其实是因为大家在词句运用的细节上存在问题所导致的。AEIS写作的每个词汇和句子考生都需要注重正确合理地使用,下面小编一个热点词汇indicate的高分用法细节。
当然,除了indicate这个词本身,考生也需要了解其相关词汇的正确用法,来拓展自身对词汇的理解和运用技巧,下面这3个indicate相关的词汇indication,indicator和indicative的用法大家要掌握好:
1. indication
先来看第一个词汇indication,这个词汇的词性为名词,含义也是表明;显示;象征之类的意思,用英文来理解,An indication is an act of indicating something。大家也可以理解成clue或是suggestion之类的含义。这个词汇比较常见的用法是give sb. an indication of或者be an indication of,都可以用来替代indicate在句子里发挥出同样的意思,比如:
a. The drastic decline in the numbers of amphibians worldwide indicates the global pollution of water and air.
b. The drastic decline in the numbers of amphibians worldwide gives scientists an indication of the global pollution of water and air.
c. The drastic decline in the numbers of amphibians worldwide is an indication of the global pollution of water and air.

2. indicator
这个词汇同样也是indicate的名词形式,这个词汇的英文解释是an object that indicates the state or level of something。从其定义上就可以看出,这个词和上面的indication虽然同为名词,但还是存在一定区别的,具体来说,indication是一个比较抽象的概念,而indicator则有具体的对象,是能够暗示或表明某件事某个现象的具体事物。还是通过实际例句来说明,刚才indication里给出的例句a可以这么变:
a. The drastic decline in the numbers of amphibians worldwide indicates the global pollution of water and air.
b. The number of amphibians worldwide is used as an indicator of global pollution of water and air.
大家可以看出,想要使用indicator的情况下,必须要有具体的对象,也就是例句中的the number of amphibians worldwide,再来看这几个句子:
c. Nitrogen oxides are used by scientists as an indicator ofeconomicactivity and of theeffectiveness of pollution-control measures.
d. Gold prices are often seen as an indicator of inflation.
e. The stock market is seen as a leading indicator of economic growth.
另外,大家如果平时比较关心金融商业类的新闻报道,那么应该会经常看到这个词组economic indicators,这个词指的一般是经济类相关的各种数字数据,比如失业率或是通货膨胀率等等,比如:
f. Economic indicators suggest that prices will go up.
那么既然可以用来指数字,下面这个用法对不对呢?
High crime rates are an indicator of a decline in moral standards.
这里小编要强调一下,这个用法本身是错误的。大家需要注意一点,这句话的主语是high crime rates而不是crime rates,indicator一般指代的都是无属性没有修饰的某个事物或是数值,一旦带上了形容词,这个主语本身就已经不是indicator而直接就是一个结果了,这种时候主语本身就带有了indication的抽象概念。以上面这个句子为例的话,犯罪率这个数据可以作为道德标准(是否)下降的indicator,但高犯罪率本身就已经是道德标准下降的indication了。这个解释可能有点绕,大家来看一下这个句子的正确写法:
High crime rates are an indication of a decline in moral standards.
Crime rates are used as an indicator of a decline in moral standards.
3. indicative
最后再来说说indicate的形容词形式indicative的用法,这个词的词义是suggestive or serving as a sign of something,用在句子里可以以be indicative of来替换indicate,比如:
a. The drastic decline in the numbers of amphibians worldwide indicates the global pollution of water and air.
上面这个句子就可以替换成:
b. The drastic decline in the numbers of amphibians worldwide is indicative of the global pollution of water and air.
再给大家几个例句参考一下:
c. Thin tree rings are indicative of slow tree growth. [=Thin tree rings indicate that a tree has grown slowly]
d. Provocative images in the media are indicative of the vibrant competition in the media.
