Yet doctors in the United States say babies begin learning on their first day of life.Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregivers. This is how babies learn to connect and communicate with other human beings.One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then，they played a recording of a short story. On the day the baby was born，the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way，he would hear a different story. The researchers say the baby clearly liked the story he had heard before he was born. They say the baby would move his mouth so he could hear the story again and again.Another study shows how mothers can strongly influence social development and language skills in their children.Researchers studied the children from the age of one month to three years. Theresearchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children's activities and did not interfere unnecessarily. They tested the children for thinking and language development when they were three years old. Also，the researchers observed the women for signs of depression.The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they heard.These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring，even when they suffered from depression.【解题导语】本文主要讲述了婴幼儿的智力发育情况，通过两个实验表明：婴儿在生命的第一天就可以开始学习，母亲的情感能强烈地影响孩子的社会发展和语言技巧。

2016级高一跟踪练习(31)·答案
1.C 【解析】胶体粒子虽然能吸附溶液中带电微粒，但是整个胶体|(分散系)是不带电的。
胶体粒子是不能通过半透膜的，溶液可以。
溶液中微粒、胶体中微粒以及其他微小粒子，由于本身质量小，受到周围其他粒子的碰撞没有特定规律，所以导致运动没有规律性，即布朗运动，这不是胶体特有的性质。
2.C 【解析】A 中水在标准状况下是液态或固态；B 中不知道溶液体积，所以无法计算；C 中分子质量就是O 原子质量，所以只要质量一样，两种分子中所含氧原子个数相同，都为N A 个；铜与足量的S 反应，所以应该以不足量的铜为标准计算，铜变为Cu 2S 时为+1价，所以应该失去N A 个电子。
3.C 【解析】题干中氨分子为还原剂，失去电子，化合价升高，在B 中氨分子同样化合价升高，作为还原剂。
4.D 【解析】离子方程式书写正误判断：①是不是符合事实，比如Fe 与盐酸反应不能生成Fe 3+；②拆的对不对，将溶于水且易电离的物质(溶于水的强酸、强碱及大部分盐)拆开，拆的时候也要注意不是拆成一个一个原子型离子，原子团是不能拆开的，不能完全电离
的微粒是不能拆开的。
如SO 42—不能再拆开，HCO 3—不能拆成H +与CO 32—；③电荷是
否守恒，即等式左边所有粒子带电量与等式右边所有粒子带电量一样；
④量是否符合题中信息，有些离子反应由于反应物的物质的量之比不同(过量与不足)可能会导致离子反应方程式不同(离子反应方程式不仅仅表示反应微粒之间反应的结果，即产物问题，还表示反应微粒之间的个数关系，即微粒个数比例关系)。
如向Ca(OH)2中通入CO 2不足与过量的问题，向NaHSO 4溶液中滴加Ba(OH)2溶液的问题等。
5.A 【解析】此类题可以利用氧化还原反应中的“强强弱弱”规律判断，即氧化还原反应发生了，就说明氧化剂的氧化能力比氧化产物强，还原剂的还原能力就比还原产物强。
判断的时候要看清楚题中要求是氧化性还是还原性，另外每个反应中具体物质体现的是什么性质，不要简单的根据左边比右边强判断。
6.C 【解析】由于Al 3+ + 3OH — = Al(OH)3 ↓ Al(OH)3 + OH — = AlO 2— + 2H 2O Ba 2+ + SO 42— = BaSO 4↓ ，根据题中数据可知，加入全部Ba(OH)2后，硫酸根离子全部
沉淀，但是此时铝离子先变为Al(OH)3，后又全部溶解了。
当加入Ba(OH)21.5mol 时Al
3+全部沉淀完，继续滴加Ba(OH)2后，继续生成BaSO 4的同时Al(OH)3在溶解。
但是生成的固体质量更大，所以总体固体质量在增加。
7.(1)2NH 4Cl + Ca(OH)2 = CaCl 2 + 2NH 3·H 2O
(2) NH 4Cl
(3) 取少量最后一次洗涤液于试管中，滴加少量硝酸酸化的硝酸银溶液，观察是否产生白色沉淀，如果产生白色沉淀就证明没有洗涤干净，否则洗涤干净 (4) 样品质量和反应后固体质量
【解析】由于Ca(OH)2是强碱，可以反应制取弱碱氨水，同时生成CaCl 2，然后CaCl 2与H 2O 2反应生成CaO 2与HCl ，氨水再与盐酸反应可以重新变为NH 4Cl 。
注意可以循环使用的是从反应物中找，不要回答CaCl 2与HCl ，以为它们是反应中产生的物质。
沉淀是否洗净的方法(操作、现象、结论)应该说明是取最后一次洗涤液，然后再做实验。
