某中学地理学习小组拟设计一个简便易行的小实验,比较说明某种地理现象。实验步骤:①放置在阳光(或者其它有较强的光源)下,保证两个玻璃盘接受同样的光照射,每隔1小时观察一次温度计,并记录温度;②将一些土壤分别放入两个玻璃盘,用剪刀将塑料瓶拦腰剪断,将底部碗状部分倒扣在盛有土壤的一个玻璃盘中;③在塑料瓶顶部钻一个小洞,将一温度计插入其中,并将另一个温度计悬挂到另一个玻璃盘上。据此完成下题。

该实验能证明的现象及其正确的步骤是                                     

A.热力环流,①②③

B.地面热容量比较,③①②

C.温室效应,②③①

D.城市热岛效应,②①③

答案

答案:C

本题考查大气的保温作用。将一些土壤分别放入两个玻璃盘,用剪刀将塑料瓶拦腰剪断,将底部碗状部分倒扣在盛有土壤的一个玻璃盘中,使损伤的地面辐射减少,保温作用增强,温度计读数高。所以本题选择C选项。

Dear Aunty,

     I work at a supermarket, and another girl and I share tasks we must finish before leaving. But she takes

half an hour to do something I can do in ten minutes. She always has a story to tell me and stops working

when she does. My boss is angry at both of us, but it's not my fault. I don't want to rat on her, but what

else can I do?

Dear Flustered,

     Let me propose a better way. Make a log of all the tasks you share, then suggest to your boss that for

efficiency your duties could be divided into two separate checklists. If he's reluctant, go to plan B: the next

time this girl starts telling you a story, stop working to listen and call your boss over to hear what a great

storyteller she is. I'm sure he'll take it from there.

Dear Aunty,

     I'm a college student in the Philippines who wants to be wise with money. I'm not an economics or

business major student and I don't know anything about stocks. But I really want to buy assets and invest.

I receive about 15,000 pesos every school term from my educational plan. I don't have any idea how I should

spend it. I don't want to just buy new clothes, or hang out with my friends because it would not be wise. I

want my money to grow. Please enlighten me.

Dear Fastbreakplay,

     Being wise with money is the No. 1 thing to learn. Start with a disciplined and systematic savings plan.

When your savings reach a sizeable amount, then you may start investing. In the meantime, invest in yourself

by reading up on stock markets and capital markets. Follow the news. Before I started investing during my

senior high school years, I had already studied stock market data of the past century as I believe markets tend

to repeat themselves. If you master this skill, you will master your reading of the markets.
