Question

Most of us seem to reach our peak of alertness (警覺) around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.

Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.

However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.

By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.

What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.  

In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.

While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.

【解析】

試題分析：本文主要講述了在每天的不同的時間適合完成不同的任務的效果是不一樣的，早晨適合短時記憶，下午適合長時記憶。

1.D 推理題。根據第二段1,2行Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day.說明早早晨短時記憶的效果較好，那么在考試之前的這個時候復習功課是值得。故D項正確。

2.A 推理題。根據第三段1,2行However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later.說明長時記憶在下午的效果比較好，所以你兩天后又考試在下午復習效果較好。故A項正確。

3.C 細節題。根據第四段By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.說明在早晨學一些與數字有關的內容是合適的，故C項正確。

4.A 主旨大意題。本文主要講述了在每天的不同的時間適合完成不同的任務的效果是不一樣的，早晨適合短時記憶，下午適合長時記憶，故A項說法正確。
