2020年8月1日雅思阅读考试真题答案
8月1号进行了八月初的第一场雅思的考试，相信大家对真题以及答案会非常的感兴趣、今天就由店铺为大家介绍2020年8月1日雅思阅读考试真题答案。
一、考题解析
P1 土地沙漠化
P2 澳大利亚的鹦鹉
P3 多重任务
二、名师点评
1.8月份首场考试的难度总体中等，有出现比较多的配对题，没有出现Heading题，其余主要以常规的填空，判断和选择题为主。文章的话题和题型搭配也是在剑桥真题中都有迹可循，所以备考重心依然还是剑桥官方真题。
2. 整体分析：涉及环境类（P1）、动物类（P2）、社科类（P3）。
本次考试的P2和P3均为旧题。P2是动物类的话题，题型组合为：段落细节配对+单选+summary填空，难度中等。题型上也延续19年的出题特点，出现配对题，考察定位速度和准确度。P3也出现了段落细节配对，主要是段落细节配对+单选+判断。三种题型难度中等，但是文章理解起来略有难度。
adaptive3. 部分答案及参考文章：
Passage 1：土地沙漠化
题型及答案待确认
Passage 2：澳大利亚的鹦鹉
题型：段落细节配对+单选+Summary填空
技巧分析：由于段落细节配对是完全乱序出题，在定位时需要先做后面的单选题及填空题，最大化利用已读信息来确定答案，尽量避免重复阅读，以保证充分的做题时间。

Passage3： multitasking
Multitasking Debate—Can you do them at the same time？
Talking on the phone while driving isn＇t the only situationwhere we＇re worse at multitasking than we might like to think we are. Newstudies have identified a bottleneck in our brains that some say means we arefundamentally incapable of true multitasking. If experimental findings reflectreal-world performance， people who think they are multitasking are probablyjust underperforming in all-or at best， all but one -of their parallelpursuits. Practice might improve your performance， but you will never be asgood as when focusing on one task at a time.
The problem， according to René Marois， a psychologist atVanderbilt University in Nashville， Tennessee， is that there＇s a sticking pointin the brain. To demonstrate this， Marois devised an experiment to locate nteers watch a screen and when a particular image appears， a red circle，say， they have to press a key with their index finger. Different colouredcircles require presses from different fingers. Typical response time is about half a second， and thevolunteers quickly reach their peak performance. Then they learn to listen todifferent recordings and respond by making a specific sound. For instance， whenthey hear a bird chirp， they have to say ＂ba＂； an electronic sou
ndshould elicit a ＂ko＂， and so on. Again， no problem. A normal personcan do that in about half a second， with almost no effort. The trouble comeswhen Marois shows the volunteers an image， then almost immediately plays them asound. Now they＇re flummoxed. ＂If you show an image and play a sound atthe same time， one task is postponed，＂ he says. In fact，if the second taskis introduced within the half-second or so it takes to process and react to thefirst， it will simply be delayed until the first one is done. The largestdual-task delays occur when the two tasks are presented simultaneously； delaysprogressively shorten as the interval between presenting the tasks lengthens（See Diagram）.
There are at least three points where we seem to getstuck， says Marois. The first is in simply identifying what we＇re looking  can take a few tenths of a second， during which time we are not able tosee and recognise a second item. This limitation is known as the＂attentional blink＂： experiments have shown that if you＇re watchingout for a particular event and a second one shows up unexpectedly any timewithin this crucial window of concentration， it may register in your visualcortex but you will be unable to act upon it. In
terestingly， if you don＇texpect the first event， you have no trouble responding to the second. Whatexactly causes the attentional blink is still a matter for debate.
A second limitation is in our short-term visual ＇s estimated that we can keep track of about four items at a time， fewer ifthey are complex. This capacity shortage is thought to explain， in part， our astonishinginability to detect even huge changes in scenes that are otherwise identical，so-called ＂change blindness＂. Show people pairs of near-identicalphotos -say， aircraft engines in one picture have disappeared in the other -andthey will fail to spot the differences （if you don＇t believe it， check out theclips at /~rensink/flicker/download）. Here again， though， thereis disagreement about what the essential limiting factor really is. Does itcome down to a dearth of storage capacity， or is it about how much attention aviewer is paying？
A third limitation is that choosing a response to astimulus -braking when you see a child in the road， for instance，or replyingwhen your mother tells you over the phone that she＇s thinking of leaving yourdad -also takes brainpower. Selecting a response to one of thes
e things willdelay by some tenths of a second your ability to respond to the other. This iscalled the ＂response selection bottleneck＂ theory， first proposed in1952.
Last December， Marois and his colleagues published apaper arguing that this bottleneck is in fact created in two different areas ofthe brain： one in the posterior lateral prefrontal cortex and another in thesuperior medial frontal cortex （Neuron， vol 52， p 1109）. They found this byscanning people＇s brains with functional MRI while the subjects struggled tochoose among eight possible responses to each of two closely timed tasks. Theydiscovered that these brain areas are not tied to any particular sense but aregenerally involved in selecting responses， and they seemed to queue theseresponses when presented with multiple tasks concurrently.
