Question

B [2015 •齊魯19所名校高三調(diào)研】

Can you believe your eyes? A recent experiment sug?gests that the answer to that question may depend on your age.

Martin Doherty ， a psychologist at the University of Stirling in Scotland,led the team of scientists. In this experi?ment, Doherty and his team tested the perception(觀察力〉of some people, using pictures of some orange circles. The re?searchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.

The first group of pictures showed two orange circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 per cent of the time. Adults identified the correct circle 95 per cent of the time.

Next,both groups were shown pictures where the orange circles,again of different sizes, were surrounded by grey cir?cles. Here's where the trick lies. In some of the pictures, the smaller orange circle was surrounded by even smaller grey circles—making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger grey circles―so it appeared to be smaller than the real smaller orange circle.

 When young children aged 4 to 6 looked at these tricky pictures ?they weren't fooled―they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one,and adults got it wrong most of the time.

As children get older,Doherty said,their brains may de?velop the ability to identify visual context. In other words, they will begin to process the whole picture at once ： the tricky

grey circles,as well as the orange circle in the middle. As a result,they're more likely to fall for this kind of visual trick.

5.Doherty and his team of scientists did an experiment to evaluate .

 

A.     children's and adults' eyesight

B.     people's ability to see accurately

C.     children's and adults' brains

D.     the influence of people's age

6.When asked to find the larger circle, .

 

A.     children at 6 got it wrong 79 % of the time with no grey ones around

B.     only adults over 1.8 got it right 95% of the time with grey ones around

C.     children at 4 got it right about 79% of the time with grey ones around

D.     adults got it right most of the time with grey ones around

7.According to the passage, we can know that .

 

A.     a smaller orange circle appears bigger on a white back?ground

B.     an orange circle appears bigger than a grey one of the same size

C.     a circle surrounded by other circles looks bigger than its real size

D.     a circle surrounded by bigger ones looks smaller than its real size

8.Why aren't younger children fooled?

 

A.     Because they are smarter than older children and adults.

B.     Because older people are influenced by their experi?ence.

C.     Because people's eyes become weaker as they grow older.

D.     Because their brains can hardly notice related things together.

Answer 1

B [文章大意]本文是一篇說明文，講述了觀察力與年齡有關(guān)，年齡不同，觀察力也不同。

5.B 細節(jié)理解題。根據(jù)第二段第二句"In this experiment,Doherty and his team tested the perception(觀察力)of some people."，，可知B項正確。

6.C 細節(jié)理解題。根據(jù)第三段倒數(shù)第二句"Four-year-olds identi?fied the correct circle 79 per cent of the time."及第五段第一句可知C項正確。

7.D細節(jié)理解題。根據(jù)第四段的內(nèi)容尤其是最后一句"And the larger orange circle was surrounded by even bigger grey circles— so it appeared to be smaller than the real smaller orange circle.，， 可知D項正確。

 8.D推理判斷題。根據(jù)第四、五、六段的內(nèi)容可知D項正確。
