Tired of telling students to ask questions and to think about what they were doing, Damien Hynes, a high school geography teacher in Australia, decided to do an experiment to test what he had long been thinking．He wrote some well-organized nonsense （something untrue） on the blackboard．The students simply copied it but very few asked any questions．This shows that students are willing to believe anything given by teachers．The story is repeated in support of the Project for Enhancing Effective Learning （PEEL）．

PEEL was carried out by some teachers and researchers in Melbourne who had concluded that normal teaching methods seldom achieve their intended goals; what the teachers think they are teaching is one thing and what the students actually learn is something else．Students’ lack of an over-all view of learning goals and their concentration on test scores make them see each lesson as a separate activity．

Researchers realized that many students do not come into class empty-headed but have their own explanations of how the world works．Their own ideas can remain important to them even when they differ from scientific explanations that are learned later．In fact such ideas are hardly affected by traditional teaching．Students accept the teacher’s scientific explanation, but do not drop their own．They simply keep both and use them practically: in a class test, they copy the teacher’s idea, but in real life they use their own．

Clearly what was needed was to make students understand their learning process（过程）, and this is what the PEEL teachers set out to deal with．On the surface,（表面） a class being taught by PEEL methods only differs from an ordinary class in being a little noisier, because more people are talking．But there are some meaningful changes．Students are given much more time to express their views, and teachers don’t make immediate judgment．The students are allowed to guide what is done in class and their own ideas are always respected．This draws their attention to the actual learning process, and they become responsible for their own progress．

小题1:The aim of Hynes’ experiment was to ______．

A．show that students didn’t think about what they learnt

B．prove the effectiveness of the project known as PEEL

C．test students’ general knowledge about geography

D．encourage students to ask more questions in class小题2:Why did some teachers and researchers carry out PEEL?

A．the teacher does not give the usual scientific explanations

B．students always have their own knowledge of the subject

C．more attention is paid to the students’ own ideas

D．the best explanations are given by the students小题4:What is Damien Hynes？

B．He is a geography teacher and a researcher in Australia

C．He is a teacher teaching geography in a high school in Austria

D．He is a high school geography teacher in Austria．

材料1：在重庆市西南部，江津区的几江街道办事处办公大楼被中国网民称为“国内第一豪华街道办事处”。德感街道办事处篆山坪村办公楼进楼需过两扇高约4米、宽可进轿车、上面镶嵌狮子的大铁门，站在直径1米多的罗马柱门框下，需仰头才能看到房顶，楼内有21间房，面积为1200平方米，出入的是11名以深蓝色西服为工作服的男女。事实上，要是再把目光投向重庆市更高级别的政府部门、单位，办公楼则更是一家赛一家庞大和豪华。如果再把目光从三峡库区、从重庆市投向全中国，类似的情况是有过之而无不及。按照建设部的说法，中国662个城市、2万多个建制镇中，约有五分之一的城镇存在类似情况。在国家扶贫开发工作重点县山西省浑源县，2006年县财政预算还不到1亿元，但该县检察院却耗费1000多万元建起豪华办公楼。山西省忻州煤矿安全监察局仅有10名工作人员，却有四五十间带卫生间的超大面积的办公室，有36套超大面积住房。另外，外观状似“白宫”的河南省郑州市惠济区政府办公楼，更以其山水景观式的建筑格局和35万平方米的占地规模闻名天下。

材料2：2007年3月，国务院 * * 温 * * 在《政府工作报告》中确认了这些情况的存在和严重性：每年的政府行政管理费用已经膨胀到7000亿元以上。“现在，不少地方、部门和单位讲排场、比阔气，花钱大手大脚，奢侈之风盛行，群众反应强烈。这种不良风气必须坚决制止。要严格控制行政机关新建、扩建办公大楼，严禁建设豪华堂馆所，切实规范公务接待行为，堵塞管理漏洞，努力降低行政成本，建设节约型政府。”

材料3：“各地的豪华办公楼说明了政府机关在行使权力时有大量的灰色收入。”清华大学廉政与治理研究中心副主任任建明表示。事实也有佐证。2004年10月，公安部警务督察局在河北省公安厅的协助下，查处了张家口市公安局经侦支队大肆罚款创收，继而盖起造价2000万元的宿舍楼和豪华办公楼的情况；2004年11月，云南省红河哈尼族彝族自治州中级法院花费3000多万元盖办公楼，超出财政预算1000万元，由于无钱支付工程款被建筑公司告上法庭；2006年5月，山西省浑源县检察院利用参与公路治超的机会，动用了上千万元罚没款盖豪华办公大楼被查处。事实上，除了正常的税收外，现在公安、工商、卫生、计生„„几乎每一个有行政收费、罚款等经济来源的地方政府部门都在千方百计“创收”，尽管国家规定了“收支两条线”政策，但是各种部门“总是有办法把大部分钱要回来”，除了部分用来发放员工福利外，更多的款项都被用来进行各种基础建设。

根据材料，简要分析“豪华办公楼”现象。
