Question

【题目】Our body clock, or natural body rhythm, influences our energy and alertness. Paying attention to it can help us choose the suitable time of the day when we best perform specific tasks.

The reality, however, is that most of us organize the time around work demands, school deadlines, commuting or social events. Doing whatever the body feels like doing is a luxury in today’s fast-paced modern society.

But that doesn’t mean it isn’t worth trying. Obeying our body clock has significant health benefits. Disrupting our natural body rhythm, on the other hand, has been linked to problems such as depression, obesity, or headache, says Steve Key, a biology professor.

When the body clock can synchronize (使…同步) the rhythms of its natural processes, it “gives us an advantage in daily life”, says Key.

According to him, when it comes to cognitive (认知的) work, most adults perform best in the late morning. As our body temperature starts to rise just before awakening in the morning and continues to increase until midday, our memory, alertness and concentration gradually improve.

However, he adds, our ability to concentrate typically starts to decrease soon thereafter. Most of us are more easily distracted (分心) between noon and 4 pm.

Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm, making that a good time for a nap.

Surprisingly, tiredness may increase our creative powers. For most adults, problems that require open-ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.

When choosing a time of the day to exercise, paying attention to your body clock can improve results. Physical performance is usually best from about 3 to 6 pm, says Michael Smolensky, a professor of biomedical engineering.

Of course, not everyone’s body clock is the same, making it even harder to synchronize natural rhythms with daily plans.

Answer 1

【答案】

【1】A

【2】D

【3】B

【4】C

【解析】

试题分析:这篇文章讲的是生物钟，先简单介绍了一下生物钟，然后讲人们应该好好的利用生物钟。破坏生物钟可能会对人的身体带来问题。接着讲了生物钟在不同的时刻对人们的身体有着不同的影响力。

【1】A细节理解题。根据Paying attention to it can help us choose the suitable time of the day when we best perform specific tasks.可知注意生物钟能够帮助我们在一天中选择最合适的事件做特殊的任务。故选A。

【2】D细节理解题。根据Disrupting our natural body rhythm, on the other hand, has been linked to problems such as depression, obesity, or headache, says Steve Key, a biology professor.可知破坏生物钟可能会导致很多问题，比如压抑、肥胖或者头疼。这只是说有可能，但不是必然的，D选项太过武断。故选D。

【3】B细节理解题。根据For most adults, problems that require open-ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.可知，对一个成年人来说，当他们晚上疲惫的时候反而能完美的解决复杂的问题。故选B。

【4】C主旨大意题。这篇文章讲的是生物钟，先简单介绍了一下生物钟，然后讲人们应该好好的利用生物钟。破坏生物钟可能会对人的身体带来问题。接着讲了生物钟在不同的时刻对人们的身体有着不同的影响力。所以综合来讲，这篇文章讲的是生物钟与人们的健康。故选C。
