[多选题]校本课程是促进学校特色发展的重要途径。下列说法中正确的有( )。

应该加强一线教师的课程开发能力建设

校本课程开发可以借助校外专家的指导

地方教育行政部门应该鼓励因校制宜开发校本课程

解析：校本课程开发不能等同于学校课程（即学校内所实施的一切课程）.它更强调行动与过程，不要求自编教材，可以是活动方案或活页资料。校本课程是学校自主决定的课程，它的开发主体是教师，教师可以与专家合作。校本课程可以弥补国家课程、地方课程的不足，有利于学生主动性的发展，地方教育行政部门应该鼓励因校制宜开发校本课程。

[单选题]家长许诺：如果孩子考第一名，奖励孩子一台平板电脑，这诱发了孩子学习的( )动机。

外在

解析：动机从来源上可以划分为两大类：内在动机和外在动机。在学校教育中，有多种多样的外部条件，可以吸引、激励、诱发学生，成为促进他们积极活动的动力源泉，如父母的鼓励、教师的表扬、竞争的奖励等；同样，也有各种各样的外部条件可以起到抑制、约束和限制不良行为表现的作用，如教师的批评、学校的处分、竞争的失败等。这种由外部力量和外部环境（即诱因）激发而来的动机，称为外在动机。

[单选题] On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more than they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log half that time. All in all, however, children's leisure time dropped from 40% of the day in 1981 to 25%. "Children are affected by the same time crunch (危机) that affects their parents," says Sandra Hofferth, who headed the recent study of children's timetable. A chief reason, she says, is that more mothers are working outside the home.(Nevertheless, children in both double-income and "male breadwinner" households spent comparable mounts of time interacting with their parents,19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.) All work and no play could make for some very messed-up kids."Play is the most powerful way a child explores the world and learns about himself," says T. Berry Brazelton, professor at Harvard Medical School. Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it. The children sampled spent a quarter of their rapidly decreasing "free time" watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they're spending less time in front of the TV set, however, kids aren't replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let's face it, who's got the time?

Nowadays, the troublesome problem is that American kids

are engaged in lots of structured activities

解析：1.推断题。文中第三段提到“Play is the most powerful way a child explores the world and learns about himself”即玩耍是儿童探索世界和了解自己最有效的方式，D选项符合题意，故选D。 2.细节题。文中第一段提到，现在的孩子每周待在学校的时间比1981年多8个小时，而且参加更多如足球、芭蕾舞等活动，尤其在体育运动上花费的时间也增多了；分别对应选项中的A、B、D。最后一句提到“children's leisure time dropped from 40% of the day in 1981 to25%”，即孩子放松、玩耍的时间变少了。所以C选项不是现在孩子面临的情况，故选C。 3.细节题。文中第二段第二句提到“A chief reason，she says，is that more mothers are working outside the home.”主要原因是更多的妈妈们在外面工作，故选A。 4.细节题。文中第三段最后一句话提到“Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it．”即无组织的玩耍可以鼓励孩子的独立思考，但是3到12岁的孩子每周只有12个小时的时间做这些。所以D选项做更多有组织的活动，是现在孩子的一个很麻烦的问题。 5.细节题。文中最后一段提到，即使他们在电视上花费的时间更少的话，“Despite efforts to get kids more interested in books，the children spent just over an hour a week reading.”即每个孩子每周在阅读上花费的时间也只是一个多小时，故选项D正确。
