The baby is just one day old and has not...

The baby is just one day old and has not left hospital yet. She is quiet but alert(警觉). The researchers have placed a white card with two black spots on it twenty centimeters from her face. She stares at it carefully.

A researcher removes the card and replaces it by another one, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视)starts to lose its focus until a third card is presented. The third card has three black spots on it. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world? Or do newborns simply prefer more to fewer?

The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When a little older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again.

Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats (鼓声)than when they heard just two; likewise(同样地)when the researchers started with drumbeats and moved to spots.

1.The experiment described in Paragraph 1 is mainly about the baby’s ______.

A. sense of hearing    B. sense of sight    C. sense of touch    D. sense of smell

2.What does the underlined word it in paragraph 2 refer to?

A. the card    B. the baby    C. the comb    D. the key

3.According to the passage, babies have a strong sense of changing in ______.

A. the size of cards    B. the colour of pictures    C. the shape of patterns

D. the number of objects

4.Why did the researchers test the babies with drumbeats?

A. To reduce the difficulty of the experiment.

B. To see how babies recognize sounds.

C. To carry their experiment further.

D. To keep the babies’ interest.

5.Where does this passage probably come from?

A. Science fiction.    B. Children’s literature.

C. An advertisement.    D. A science report

 

1.B 2.A 3.D 4.C 5.D 【解析】本篇是一篇科普类阅读。研究人员通过一些卡片上黑点的数量变化和鼓声变化来检验婴儿对于数量变化的敏感程度,发现数量相对多的时候,比较容易引起婴儿的注意,使他们变得更加兴奋。 1.题意:第1段所描述的实验主要是关于婴儿的__________。考查细细节理解题。A. sense of hearing 听觉; B. sense of sight视觉;C. sense of touch触觉; D. sense of smell嗅觉。根据文章第一段文中的She stares it carefully. Her gaze starts to lose its focus.(她仔细地盯着它。她的目光开始失去焦点。)可知,本段是对孩子的视觉实验。故选B。 2.题意:第2段中划线的词it指代什么?考查细节理解。 A. the card 卡片; B. the baby婴儿;C. the comb梳子;D. the key钥匙。A researcher removes the card and replaces it by another one, this time with the spots differently spaced.意思是一个研究人员把卡片去掉,换上另一张,这次用不同间隔的斑点。根据句意和语境可知it指代内容是the card;故选A。 3.题意:根据文章,婴儿在______________方面变化有强烈的感觉。考查细节理解。A. the size of cards卡片大小;B. the colour of pictures图片的颜色;C. the shape of patterns图案的形状;D. the number of objects物体的数量。根据第三段第一句The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes.(同样的实验,但在两点前出现三个点,当斑点的数量变化时,显示出同样的兴趣。)结合语境可知婴儿对物体的数量变化有强烈的感觉。结合句意和语境可知选D。 4.题意:为什么研究人员用鼓声测试婴儿?细节理解题。A. To reduce the difficulty of the experiment. 减少实验的难度;B. To see how babies recognize sounds. 看婴儿如何识别声音; C. To carry their experiment further. 进一步进行实验;D. To keep the babies’ interest. 保持孩子们的兴趣。前三段中研究人员先是通过卡片上的黑点来测验婴儿对于数量的变化的敏感程度;根据第四段中的The effect even crosses between senses...three drumbeats than when they heard just two;likewise(同样地)when the researchers started with drumbeats and moved to spots.( 甚至在感官之间产生交叉效应。婴儿被反复证明两个斑点变得兴奋时,他们听到鼓三声鼓声比他们听到两声鼓声更兴奋;同样当研究人员开始用鼓声,再用移动点,发现数量相对多的时候,比较容易引起婴儿的注意,使他们变得更加兴奋。)可知,研究人员又做了击鼓的实验,这样做的目的是更加深入地研究婴儿对于数量变化的敏感程度,故选B项。 5.题意:这段文章可能来自哪里?考查文章来源和细节理解题。A. Science fiction. 科幻小说; B. Children’s literature. 儿童文学;C. An advertisement. 广告;D. A science report一篇科学报告。本文提到了experiment和researchers等,可知是一些研究人员做了一个实验,来检验婴儿们对于数量的变化是不是敏感,所以本文属于一个科学研究报告,故选D。 点睛:首先,通过粗读,了解文章大意。其次,通过细读,理解全文。在粗读的基础上,仔细阅读题后所给的题目,根据题目要求,再有重点的返回来仔细阅读。在阅读理解的题目中,所设问题主要有以下几种方式:找主题或概括文章的中心思想、就文中的具体事实和情节进行提问、根据文章的表层意思进行深层次的推理判断等,在细读时,要根据设问的方式,进行有侧重点地阅读。1、概括文章中心思想。1)文首呈现主题句。 2)文尾出现主题句。3)首尾呼应展现主题。4)文中表述主题。前面提出问题,文中的主题由随之陈述的细节或合乎逻辑的引申在文中导出,而后再做进一步的解释。5)文章没有主题句。在这种情况下,考生要把所有的细节综合起来。进行逻辑推理,概括归纳出文章的主题句。2.掌握文章的具体事实和重要情节。在考题中,经常会见到就文章中某一具体事实和重要情节进行测试的题目。例如,第1题,考查细细节理解题。A. sense of hearing 听觉; B. sense of sight视觉;C. sense of touch触觉; D. sense of smell嗅觉。根据文章第一段文中的She stares it carefully. Her gaze starts to lose its focus.(她仔细地盯着它。她的目光开始失去焦点。)可知,本段是对孩子的视觉实验。故选B。以及第2,3,4,5题。这就要求考生在阅读时要注意辨认和记忆具体事实,重要情节,事物的起因、过程、结果及发生的地点、时间等,这些都有可能作为测试点。还有一些测试题,要求考生在理解的基础上,通过自己的思维将理解的内容系统化,比如计算、排序等题型。还有些细节理解题是通过语句的同义转换来考察学生的理解力。

It was on her 14th birthday that her first book, In the Forests of the Night, was put into publication (出版). At 16, her second book, Demon in My View, also reached the bookstore.
