【简答题】
Many parents take on the role of being their children’s preschool teacher and the responsibility of readying them for kindergarten. To achieve this goal, it is important for parents to introduce a variety of subjects in a positive and playful manner. “Learning should not be forced,”says Marion Godwin, who has taught first grade in Moorestown, N. J. for more than 30 years.“ It should be taught according to what they know and do best—and that is‘ play’. When teaching  them, play games and have fun with the subject. And parents should always be looking for‘teachable moments’.” “You want a child to be a lifelong learner, so you want to show them learning is everywhere,”she says.“If parents take the time to lay a strong educational foundation, their children will keep building on it.” Introduce children to science with hands-on activities that interest them, such as growing plants from seeds, discussing animals and how to care for pets, and observing the chemical changes that occur during cooking”, she says. “Sorting activities, simple patterns and counting games are a great way to teach children the basics of math, and taking them on field trips, singing songs and reciting rhymes also are ways to prepare them for the first day of school”, she says. “I think children are naturals when it comes to computers,” she says.“Let them play educational games on the computer and teach them how to type their first names using the keyboard. When they are more familiar with using the computer, let them find pictures of animals and places on the web. ” “Don’t criticize the child,” she says. “You can’t force them to learn something. If they don’t get something right, so what? Smile and be happy and make the experience joyful. Parents need to understand that if a child gets something wrong, they may think something is wrong with them. Keep working with them and when they get the right answer make sure you tell them how hard they worked to get the correct answer. ” 小题1:Marion Godwin tells us that we should teach the children according to their_____        . A.subjects and needs B.level and interest C.teachable moments D.strong educational foundation 小题2:According to Godwin, children should ____________________       . A.keep a pet each and care for it B.do some cooking every day C.learn science with interesting hand-on activities D.learn from the farmers and grow plants from seeds 小题3:In Godwin’s opinion, children should be encouraged to_________        . A.learn all by themselves B.play more computer games C.learn to type their first names D.learn online under instructions 小题4:What’s the best title of the passage? A.How to prepare your children for kindergarten B.Learning should not be forced C.How to be a lifelong learner D.Learning is everywhere

【简答题】天然纤维中,保暖性最好的是:
【简答题】常温下,将某一元酸HA和KOH溶液等体积混合,两种溶液的浓度和混合后所得溶液的pH如下表,请回答: 实验 编号 HA物质的量浓度(mol?L -1 ) KOH物质的量 浓度(mol?L -1 ) 混合溶液pH 甲 0.2 0.2 pH=a 乙 c 0.2 pH>7 丙 0.2 0.1 pH>7 丁 0.1 0.1 pH=9 (1)不考虑其它组的实验结果,单从甲组情况分析,若溶液中的离子为:K + ...
【单选题】常温下,将不同浓度的氨水与盐酸等体积混合,两种溶液的浓度和混合后所得溶液的pH如下表,则下列说法不正确的是 编号 氨水的物质的量浓度 (mol/L) 盐酸的物质的量浓度 (mol/L) 混合溶液的pH 第1组 0.1 0.1 pH=X 第2组 c 1 0.2 pH=7 第3组 0.2 0.1 pH>7 (  )
A.
0.1 mol/L 氨水的pH<13,第1组中X<7
B.
第2组中c 1 >0.2,混合后溶液中c(Cl - )=c(NH 4 + )
C.
第3组混合后溶液中离子浓度由大到小的排列顺序是c(OH - )>c(Cl - )>c( NH 4 + )>c (H + )
D.
采取①加少量水、②加入少量浓盐酸、③加入少量NH 4 Cl固体的措施,都可以使0.1 mol/L氨水中c(NH 4 + )/c(NH 3 ?H 2 O)增大
