3．C 从下文可知，当时“我”相信自己是正确的。be convinced that意为“确信，深信”。

4．B 下文多次提到my teacher，所以应选B项。

5．C bring指“带 到某处”。其他选项不符合文意。

6．B 从下文的her desk可知，老师把我们带到讲桌边，讲桌应在教室前面，故B项最佳。

7．B 根据下文，老师把我们安置在讲桌的两边。place意为“放置，安放，安置”。

8．A 从上文“on one side of her desk”可推知“我”站到那个同学对面，即讲桌的另一边，应是the other side。

9．C 从下段第11空后的“...it was obviously black”可知，从“我”这边，很清晰地看到那个物体是黑色的，故选择clearly。

10．C 从black和white可知，老师在问我们物体的颜色。

11．A when在此相当于considering that，意思是“考虑到 ”。本句的意思是“考虑到它明显是黑色的，我无法相信他所说的物体是白色的。”

12．B 由两人回答的颜色不同可知他们的意见不统一，所以又一次争吵起来。

13．A this time“这一次”，与文章开头提到的一次争吵呼应。

14．A 由上句两个where可知，我们交换了地点。

15．D 根据上下文，我们两人互相交换了地点，“我”看到了事物的另一面，不得不承认是白色的，(即“我”的同学刚才看到的颜色)。

16．B 由下文“from his side it was white”和“from my side was it black”可知，物体的两面颜色不同，故differently正确。

17．C 通过上句，从他那面看，物体是白色，可是只有从“我”这面看是黑色。由句子使用了倒装was it black可知，只有only符合文意。

18．B (be)in sb.'s shoes“处于某人的境地”。不及物动词stand代替了be在此表示动作，说明你看问题要站在对方的角度(换位思考)。

19．A 学会换位思考，通过对方的眼睛来看事情的situation“局面，情况，局势”。movement“运动”，condition“状况”，behaviour“行为”。

20．D 通过上文可知，只有你自己处在别人的境况下，才能“真正”理解别人，故D项。

Teens' lives hit by economy

Some teenagers are crossing their dream colleges off their lists.Others are thinking of skipping their senior trips or reducing prom(毕业舞会)costs.Many are finding their work hours cut while their expenses rise.

So，who exactly is punishing them？Is it their parents，teachers or employers？No，it's the economy.

If you are like most teenagers，you probably don't understand what“recession”，“negative economic growth”and“subprime mortgage crisis(次贷危机)”actually mean.And you probably don't spend your days watching the ups and downs of the stock market.

It's safe to say that most teens don't know much about the economy except for one thing：it's bad.But just how exactly is the economy affecting teens?

“The single largest thing I have noticed is the recession's ability to affect my college choice，”said Heather Richars from Downey High School in California，US.

“With the economic situation the way it is，I have thought less about going to a private or out-of-state university，and more about public schools in California，mainly because of the price of tuition，”said Richars.“I had been a fan of attending a private school up until this year.” The economy cuts into other areas of teenagers' lives，too.

Joey Camarda，a student at Modesto High School in California，who works at an ice cream store，said，“Probably due to the economy，I have been getting less hours at my job，and because of that，I am not getting enough money to help pay for college.”

Tara Mooney，a senior at Beyer High School，has also begun to notice that money is tight.
