Question

  You have waited 45 minutes for the valuable 10 minutes' break. But when the bell for the next class rings,you can't believe how quickly time has passed. If you have this experience,you'll know how time flies when you are having fun and drags when you are bored. Now scientists have come up with a reason why this happens.

  They have found that the brain changes its way to work according to how we direct our attention to a task. When we are bored,we pay more attention to how fast time is passing. And this makes our brains think the clock is ticking more slowly.

  Recently some researchers who wanted to understand the conditions carried out an experiment. In the experiment,twelve volunteers watched a picture when researchers monitored (監(jiān)控) their brain activities.

  The volunteers were told to first notice how long a picture appeared,then the color of the picture,and thirdly,study the both. The results showed that the brains were more active when the volunteers paid attention to more subjects.

  It is thought that if the brain is busy noticing many aspects (方面) of a task,it has to spread its resources,and pays less attention to the clock. Therefore,time seems to go by quickly. If the brain is not so active,it puts its full energy on the passing of time. As a result,time seems to move slowly.

  Next time you feel bored in class,perhaps you should concentrate on what the teacher is saying.

   D. Time goes by very slowly when we have something to do.

(   ) 3. How did the researchers do the experiment?

   B. Concentrating on things is a way to make people less bored.

   C. Time goes by slowly when the brain is noticing many things at the same time.

   D. Time goes by slowly when we concentrate on things.

   B. The importance of planning time

   C. The reavson for time flying and dragging

1. A詞義猜測題。由題目中的關(guān)鍵詞drags ,可回原文定位于第一段。根據(jù)第一段中的"you'll know how time flies when you are having fun"可知，當(dāng)你感到快樂時,就會覺得時間過得很快，那么當(dāng)你感到無聊時，就自然會覺得時間過得很慢。drags意為"過得慢"，相當(dāng)于passes slowly。

2. C細(xì)節(jié)理解題。由題目中的關(guān)鍵詞the scientists found ,可回原文定位于第二段。科學(xué)家發(fā)現(xiàn)，人腦在不同的情況下，工作方式不一樣。

3. C細(xì)節(jié)理解題。由題目中的關(guān)鍵詞How... do the experiment ,可回原文定位于第三段。通讀第三段內(nèi)容可知，研究者所做的實驗是讓志愿者觀察一幅圖同時監(jiān)控他們的大腦活動。

4. B細(xì)節(jié)理解題。由題目中的關(guān)鍵詞TRUE，可回原文定位并理解全文。人在集中精力做事時就不會感到無聊。

5. C主旨大意題。由題目中的關(guān)鍵詞the best title ,可回原文定位并理解全文。文章主要講述了研究者通過實驗來研究人們感到時間過得快或慢的原因。
