Question

They baby is just one day old and has not yet left hospital. She is quiet but alert (警覺). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝視) starts to lose its focus - until a third, with three black spots, is presented. 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 slightly 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 than when they heard just two; likewise(同樣地) when the researchers started with drumbeats and moved to spots.

60. The experiment described in Paragraph 1 is related to the baby’s ______.

A. sense of hearing.

B. sense of sight.

C. sense of touch.

D. sense of smell.

61. Babies are sensitive to the change in ______.

A. the size of cards.

B. the colour of pictures.

C. the shape of patterns.

D. the number of objects.

62. 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.

63. Where does this text probably come from?

A. Science fiction.

B. Children’s literature.

C. An advertisement.

D. A science report.

Answer 1

【語篇解讀】本篇是一篇說明文。文章對剛出生一天的嬰兒做實驗，通過變化紙上的黑點及鼓的敲打次數(shù)對嬰兒的視覺、聽覺進行的一個實驗。

段落	關鍵詞、句	大意推測
第一部分（Para. 1）	A white card with two……stares it carefully Remove the card and replace it……lose its focus with three black spots……Her gaze returns.	對初生嬰兒做實驗，通過對卡片上黑點的變化，看新生兒的反應。
第二部分（Para. 2）	The same experment...shows the same return..... No again. Babies pay more attention to ......	根據(jù)實驗所得嬰兒的反應情況進行分析。

60. B。推理判斷題。難度：較易。根據(jù)第一段文中的句子She stares it carefully. Her gaze starts to lose its focus.可知，本段是對孩子的視覺實驗。

61. C。事實細節(jié)題。難度：較大。此題有很多干擾信息，所以容易誤選。Babies pay more attention to squares moving randomly on a screen when their number changed from two to three,or three to two.可知，答案選C。

62.C。推理判斷題。難度：中等。題干核心詞drumbeats, 根據(jù)文章第一段得知對孩子的視力進行試驗，接下來用鼓來對孩子的聽力繼續(xù)試驗。所以答案選擇C。

63．D。推理判斷題。難度：較易�？v觀文章，這是一篇試驗報告，所以答案選D。

【難句學習】：

1.She looks at it for twice as long as it did at the previous card.

翻譯：她再次看這個圖片就想看先前那張圖片時間一樣長。

分析：as it did ,此處的did,即前半句的look的過去式look。注意動詞的替代用法。

2. The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes.

翻譯: 但是，在兩個點之前先給孩子看三個點，同樣實驗顯示孩子對點的數(shù)量變化一樣返回興趣。

分析：本句中用了兩個逗號作為插入成分。句子結構：The same experiment shows the same return of interest……

3. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two……

翻譯：那些多次被給兩個黑點的孩子，當他們聽到三聲鼓聲的時候比聽到兩聲鼓聲更興奮。

分析：本句用了who 引導定語從句，修飾先行詞babies。另外，本句結構注意：more excited when……than when……
