一、雅思阅读隐性定位词中Proportion=%.
通常，在我们审题的时候，会发现每个问题的选项都有特定的信号词出现，例如下面的问题中，我们可以明显看到问题6中出现的proportion，因此我们在选择相对的答案的时候，可以找找文中有没有相对应百分比的对照。然后首先看看这些百分比内容的匹配性，因此像这种隐形定位词能够有效提高我们做题的速度。
Question 1-6
Reading Passage 1 has nine sections, A-l.
Which section contains the following information?
Write the correct letter, A-l, in boxes 1-6 on your answer sheet.
6. The estimated proportion of children in New Zealand with auditory problems
对应原文：
The Impact of Hearing Loss on Young Children
A. Hearing impairment or other auditory function deficit in young children can have a major impact on their development of speech and communication, resulting in a detrimental effect on their ability to lean at school. This is likely to have major consequences for the individual and the population as a whole. The New Zealand Ministry of Health has found from research carried out over two decades that 6-10% of children in that country are affected by hearing loss.
因此第6题选A
二、雅思阅读隐性定位词中Payment，通常可以用货币符号表示。
在下面的例子中，我们可以从问题中找到关于payment这个隐性定位词。从字面可以知道payment是账单的意思，就是关于金钱，或者货币符号的形式出现。所以考生可以根据相关线索优先分析这类选项。
Question 8-13
Do the following statements agree with the information given in Reading Passage 1?
In boxes 8-J3 on your answer sheet, write
TRUE：If the statement agrees with the information
FALSE：If the statement contradicts the information
NOT GIVEN：If there is no information on this
12. Johnson only received payment for his Dictionary on its completion.
对应原文：
Johnson signed the contract for the Dictionary with the bookseller Robert Dosley at a breakfast held at the Golden Anchor Inn near Holborn Bar on 18 June 1764. He was to be paid? 1,575 in instalments, and from this he took money to rent 17 Gough Square, in which he set up his 'dictionary workshop'. James Boswell, his biographer, described the garret where Johnson worked as 'fitted up like a counting house' with a long desk running down the middle at which the copying clerks would work standing up.
原文说的是分期in installments，而题干说的是only...completion，因此是False。
三、雅思阅读隐性定位词中Earlier=time.
如果出现这种描述时间的隐性信号词，那么选项若出现时间的形式可以优先查看。例如下文出现earlier，字面意思表示很早，表时间的，那么选项看看有没有表时间的。这样能大大提高做题速度。
Question 27-29
Reading Passage 3 has eight paragraphs A-H.
Which paragraph contains the following information?
Write the correct letter, A-H, in boxes 27-29 on your answer sheet.
27. Mention of a geo-engineering project based on an earlier natural phenomenon
对应原文：
D.The concept of releasing aerosol sprays into the stratosphere above the Arctic has been proposed by several scientists. This would involve using sculpture or hydrogen supplied aerosols so that sculpture dioxide would form clouds, which would, in turn, lead to a global dimming. The idea is modelled on historic volcanic explosions, such as that of Mount Pinatubo in the Philippines in 1991, which led to a short-term cooling of global temperatures by 0.5℃.Scientists have also scrutinized whether it's possible to preserve the ice sheets of Greenland with reinforced high-tension cables, preventing icebergs from moving into the sea.
原文出现时间的地方描述historic volcanic explosions, such as that of Mount Pinatubo in the Philippines，such as举例子，historic volcanic explosions对应natural phenomenon，因此选D.
四、雅思阅读隐性定位词中Refer to as= proper nouns.
当我们遇到像refer to as，这种表示要解释一个现象，一个单词意思的隐性信号词的时候。在选看选项的时候可以优先看那些专有名词的选项，换句话说就是选项有某个单词不熟悉，然后出现频率高的名词。通过下面的例子，我们可以看出：
Question 34-40
Complete the sentences.
Choose NO MORE THAN THREE WORDS from the passage for each answer.
Write your answers in boxes 34-40 on your answer sheet.
35. Plants which do not respond to light levels are referred to as.
对应原文：
For example, some species of birds' breeding can be induced even in midwinter simply by increasing day length artificially (Wolfson 1964). Other examples of photoperiodic occur in plants. A short-day plant flowers when the day is less than a certain critical length. A long-day plant flowers after a certain critical day length is exceeded. In both cases the critical day length differs from species to species. Plants which flower after a period of vegetative growth, regardless of photoperiod, are known as day-neutral plants.
回原文寻读，找到day-neutral plants是以斜体形式出现，且前面有限定are known as，可以确定是专有名词，do not respond to light levels对应regardless of photoperiod，所以填day-neutral plants.
