答案绝对是不！雅思学术阅读部分有三段很长的篇幅，随着阅读的进行，难度越来越大。这意味着，第一个要比第二个要容易一些，而最后一个要比第二个要困难一些。
如果你在第一篇文章中花了太多时间（许多考试第一次就犯了这个错误），那么你很可能会考试时间快结束才能做到第三篇也就是最后一篇文章。因此，你不需要从头至尾阅读每一段。
那你可能会问，如果我不阅读全文，我该如何回答问题？要了解的两个最重要的阅读技能是skimming 和scanning。然后，你可以使用这些技能，不需要阅读全文，就能够有策略地回答雅思考试的学术问题。
skimming也就是略读，你并不是在寻找细节，而是在大致了解段落或段落的含义。
以 “标题匹配”这种阅读题型为例。浏览以下段落以找到每个段落的基本概念。这样做将帮助你选择正确的标题。
Which paragraphs contains the following information?
Write the correct letter A-Cnext to questions 1-3 below
List of headings
I. It’s all in the brain
II. Dopamine and the brain
III. All about those nerves
IV. Introversion vs. Extroversion
V. It’s an extrovert’s world
A. Many people enjoy swaying along to the music in a nightclub. For these extroverts, a night spent dancing and talking to friends is a fun evening. But for introverts, this is the stuff of nightmares. Small talk, dense crowds and loud music can be terrifying. Even partying at home with a group of friends, though fun, can be draining. Some people would much rather be tucked up in reading a book. This is a primary difference between extroverts who on the one hand who feel energised from stimulating environments and interaction, and introverts on the other hand who feel drained and low in energy as a result of such situations.
B.Why do introverts and extroverts react so differently to the same situation? The answer has to do with some key differences in the way their brains are wired. One major difference between the brains of introverts and extroverts is related to their response to the neurotransmitter dopamine. Dopamine is a chemical released in the brain that provides the motivation to seek external rewards like earning money or attracting a mate. It creates a sensation of pleasure as a reward for success in these endeavours. When dopamine floods the brain, both introverts and extroverts become more talkative and motivated to take risks. Introverts have the same quantity of dopamine present in their brains as extroverts. The difference is in the functioning of the dopamine which is more active in the brains of extroverts. Extroverts thrive on the dopamine-charged good feelings created when they engage the sympathetic side. Introverts rely more on a different neurotransmitter called acetylcholine. Like dopamine, acetylcholine is linked to pleasure; the difference is that acetylcholine makes us feel good when we turn inward. It powers our abilities to think deeply and focus intensely on just one thing for a long period of time. It also helps explain why introverts like calm environments; it’s easier to turn inward when we’re not attending to external stimulation. When an introvert is lounging at home in quiet solitude, lost in a book or watching Netflix, they are basking in the pleasant effects of acetylcholine
C.Another piece of the introvert-extrovert puzzle has to do with the nervous system. Both introverts and extroverts use both sides of their nervous systems at different times, just like they use both neurotransmitters. But extroverts tend to favour the opposite side of the nervous system; the sympathetic side, known as the ‘fight, flight or freeze’ system. This side mobilises us to discover new things and makes us active, daring, and inquisitive. The brain becomes alert and hyper-focused on its surroundings. Blood sugar and free fatty acids are elevated to give us more energy, and digestion is slowed. Thinking is reduced, and we become prepared to make snap decisions.
1，A节
2，B节
3，C节
VI. 无需详细阅读整个文章，而只是浏览一下，我就能了解到A段比较了性格外向的人与性格内向的人的区别，因此标题“ Introversion vs. Extroversion(内向与外向)（iv）”将是最合适的标题。我还可以看到，B部分的前几句话提到了大脑和大脑化学，因此我可以放心地假设标题“ It’s all in the brain（i）”将最好地体现该段落的主要思想。最后，C节提到了神经系统。在标题（iii）中，“All about those nerves”最能概括该想法。请记住，段落标题是该段落的摘要。
A（iv）节
B（i）节
C节（iii）
略读的另一个重要原因是没有时间阅读整篇文章，而略读会让我们熟悉该文章以及信息所在的位置。这很重要，因为寻找问题的答案时，我们就知道在哪里寻找！
