專八改錯練習(xí)第二十六篇：

Is language, as food, a basic human need? Judging __1__
from the drastic experiment of Frederick in the
13th century it may be. Hoping to discover what
language a child would speak if he heard mother __2__
tongue, he told the nurses to keep silent.
Today no such drastic deprivation exists as ordered __3__
by Frederick. Furthermore, some children are still __4__
backward in speaking. Most often the reason for this is that themother is insensitive to the cues and signals of the infant, whose brain is programmed to
mop up language rapidly. There are critical times, it seems, when children learn more readily. Ifthese sensitive periods are neglected, the ideal time for
acquiring skills passes away and they might never be __5__
learned so easily again.
Linguists suggest that speech milestones are reached in a fixed sequence and at a constant age.But there are cases where speech has started late in a child
who eventually turns up to be of high IQ. Recent __6__
evidence suggests that an infant is born of the __7__
capacity to speak. But speech has to be triggered,
and this depends on interaction between the mother
and the child,where the mother realizes the cues and __8__
signals in the child's babbling, grasping, crying,
smiling, and responds to it. Insensitivity of the __9__
mother to these signals dulls the interation because
the child gets discouraged and sends out only obvious
signals. Sensitivity to the child's verbal cues is __10__
essential to the growth and development of language.

答案及解析(反白可見):
--like
作為介詞，as是“作為”的意思；like是“像……一樣”的意思。as用在此處顯然句意不通。
2.^mother--no
根據(jù)下文提到的he told the nurses to keep silent 可以判斷出，此處應(yīng)該為if he heard no mothertongue，即：如果聽不到母語，孩子會講什么語言。
^--that
句中的as是一個介詞，后面缺少賓語，后面添加的that替代the deprivation，而ordered byFrederick 是一個過去分詞短語，做定語修飾that。
4..Furthermore--Neverthless/However
Furthermore表示的是遞進(jìn)關(guān)系，而這一句話與前一句話明顯構(gòu)成的是轉(zhuǎn)折關(guān)系。
--動詞pass是指“經(jīng)過，通過，流逝”，而pass away是指“去世，死亡”，用在此處不和文意。
--out
短語turn up的意思是“出現(xiàn)，找到”，而turn out 的意思是“結(jié)果證明是……”，這句話的意思是說：有些情況是說話比較遲的孩子，最終卻被證明智商很高。
--with
be born with...意思是“與生俱來的...”是一固定短語搭配。
es--recognizes
realize意思是“認(rèn)識到，了解”，recognize的意思是“識別，認(rèn)可”，可見recognize符合文章意思：語言需要激發(fā)，而這取決于母親和孩子之間的互動，在互動當(dāng)中，母親識別孩子的牙牙學(xué)語聲和笑聲哭聲中的暗示和信號。
--them
此處指代的詞是cues and signals，所以，代詞應(yīng)該用復(fù)數(shù)形式them。
--nonverbal
根據(jù)上文判斷，babbling，prasping，crying，smiling均為非言語信號，所以是nonverbal。?
