很多托福考生一直不清楚自己的作文得分為什么提不上去，明明表述內(nèi)容和文章結(jié)構(gòu)都已經(jīng)有很不錯(cuò)的水準(zhǔn)，成績(jī)卻還是無(wú)法保證。這其實(shí)是因?yàn)榇蠹以谠~句運(yùn)用的細(xì)節(jié)上存在問(wèn)題所導(dǎo)致的。托福寫(xiě)作的每個(gè)詞匯和句子考生都需要注重正確合理地使用，下面小編就來(lái)為大家結(jié)合例句精析托福獨(dú)立寫(xiě)作中熱點(diǎn)詞匯indicate的高分用法細(xì)節(jié)。
托福獨(dú)立寫(xiě)作熱點(diǎn)詞匯indicate詞義介紹
indicate這個(gè)詞小編相信各位托福考生應(yīng)該并不陌生，這個(gè)詞匯的詞義很簡(jiǎn)單，就是表明、顯示的意思，用英文解釋那就是to point something out or to present evidence. 這個(gè)詞在獨(dú)立寫(xiě)作中可以算是比較常見(jiàn)常用的一個(gè)詞匯了，因?yàn)楠?dú)立寫(xiě)作為立論文，離不開(kāi)對(duì)各類(lèi)例證的運(yùn)用。而考生在舉出某個(gè)事例后，往往會(huì)繼續(xù)寫(xiě)以上事例表明了什么觀點(diǎn)之類(lèi)的句子，這個(gè)時(shí)候indicate就很容易被拿出來(lái)使用，因此熟悉這個(gè)詞匯的用法對(duì)大家來(lái)說(shuō)是很重要的。
托福獨(dú)立寫(xiě)作熱點(diǎn)詞匯indicate兩種用法例句分析
了解了indicate的基本詞義后，接下來(lái)小編就來(lái)為大家具體分析這個(gè)詞的標(biāo)準(zhǔn)用法，一般來(lái)說(shuō)indicate的用法主要有兩種，分別是：
1. indicate that + Subject + Verb
這個(gè)用法應(yīng)該是最常見(jiàn)的用法之一了，一般放在句子當(dāng)中，其意思往往是前面的某事某物表明了之后的某個(gè)結(jié)果結(jié)論等等，大家來(lái)看幾個(gè)例句：
a. Estimates indicate that more than 60 percent of the yearly retail sales in the U.S. are credit transactions.
b. Evidence indicates that people have always been predominantly right-handed.
c. The drastic disappearance of Foraminifera in these layers of rock indicated that something had happened at the boundary between the Cretaceous and Tertiary periods.
2. indicate + Noun
這個(gè)用法可能大家用得會(huì)稍微少一些，但其實(shí)小編認(rèn)為這反而是更能體現(xiàn)大家對(duì)這個(gè)詞匯理解和掌握水平的一種用法，因?yàn)樵谶@個(gè)用法中，indicate往往有象征，暗示之類(lèi)的意思，大家可以體會(huì)一下：
a. The drastic decline in the numbers of amphibians worldwide indicates the global pollution of water and air.
b. Record profits in the retail market indicate a boom in the economy.
c. An increase in crime indicates a decline in moral standards.
indicate相關(guān)高頻詞匯用法匯總指點(diǎn)
當(dāng)然，除了indicate這個(gè)詞本身，考生也需要了解其相關(guān)詞匯的正確用法，來(lái)拓展自身對(duì)詞匯的理解和運(yùn)用技巧，下面這3個(gè)indicate相關(guān)的詞匯indication,indicator和indicative的用法大家要掌握好：
1. indication
先來(lái)看第一個(gè)詞匯indication，這個(gè)詞匯的詞性為名詞，含義也是表明;顯示;象征之類(lèi)的意思，用英文來(lái)理解，An indication is an act of indicating something。大家也可以理解成clue或是suggestion之類(lèi)的含義。這個(gè)詞匯比較常見(jiàn)的用法是give sb. an indication of或者be an indication of，都可以用來(lái)替代indicate在句子里發(fā)揮出同樣的意思，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
這個(gè)詞匯同樣也是indicate的名詞形式，這個(gè)詞匯的英文解釋是an object that indicates the state or level of something。從其定義上就可以看出，這個(gè)詞和上面的indication雖然同為名詞，但還是存在一定區(qū)別的，具體來(lái)說(shuō)，indication是一個(gè)比較抽象的概念，而indicator則有具體的對(duì)象，是能夠暗示或表明某件事某個(gè)現(xiàn)象的具體事物。還是通過(guò)實(shí)際例句來(lái)說(shuō)明，剛才indication里給出的例句a可以這么變：
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的情況下，必須要有具體的對(duì)象，也就是例句中的the number of amphibians worldwide，再來(lái)看這幾個(gè)句子：
c. Nitrogen oxides are used by scientists as an indicator of economic activity and of the effectiveness 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，大家如果平時(shí)比較關(guān)心金融商業(yè)類(lèi)的新聞報(bào)道，那么應(yīng)該會(huì)經(jīng)常看到這個(gè)詞組economic indicators，這個(gè)詞指的一般是經(jīng)濟(jì)類(lèi)相關(guān)的各種數(shù)字?jǐn)?shù)據(jù)，比如失業(yè)率或是通貨膨脹率等等，比如：
f. Economic indicators suggest that prices will go up.
那么既然可以用來(lái)指數(shù)字，下面這個(gè)用法對(duì)不對(duì)呢?
High crime rates are an indicator of a decline in moral standards.
這里小編要強(qiáng)調(diào)一下，這個(gè)用法本身是錯(cuò)誤的。大家需要注意一點(diǎn)，這句話(huà)的主語(yǔ)是high crime rates而不是crime rates，indicator一般指代的都是無(wú)屬性沒(méi)有修飾的某個(gè)事物或是數(shù)值，一旦帶上了形容詞，這個(gè)主語(yǔ)本身就已經(jīng)不是indicator而直接就是一個(gè)結(jié)果了，這種時(shí)候主語(yǔ)本身就帶有了indication的抽象概念。以上面這個(gè)句子為例的話(huà)，犯罪率這個(gè)數(shù)據(jù)可以作為道德標(biāo)準(zhǔn)(是否)下降的indicator，但高犯罪率本身就已經(jīng)是道德標(biāo)準(zhǔn)下降的indication了。這個(gè)解釋可能有點(diǎn)繞，大家來(lái)看一下這個(gè)句子的正確寫(xiě)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
最后再來(lái)說(shuō)說(shuō)indicate的形容詞形式indicative的用法，這個(gè)詞的詞義是suggestive or serving as a sign of something，用在句子里可以以be indicative of來(lái)替換indicate，比如：
a. The drastic decline in the numbers of amphibians worldwide indicates the global pollution of water and air.
上面這個(gè)句子就可以替換成:
b. The drastic decline in the numbers of amphibians worldwide is indicative of the global pollution of water and air.
再給大家?guī)讉€(gè)例句參考一下：
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.
以上就是托福獨(dú)立寫(xiě)作中熱點(diǎn)詞匯indicate以及其名詞形式indication、indicator還有形容詞形式indicative的一些用法細(xì)節(jié)精析，結(jié)合例句為大家講解了具體的使用細(xì)節(jié)注意事項(xiàng)，希望能夠幫助各位同學(xué)更為準(zhǔn)確地在寫(xiě)作中運(yùn)用好這個(gè)詞匯提升作文詞句的水平和得分。
