Question

【題目】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 (認知的) 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.

【1】If we know our natural body rhythm well, we can ______.

A. find out the suitable time to do specific tasks

B. organize our time around work demands

C. Obeying our body clock is good for our health.

D. Disrupting our natural body rhythm can lead to obesity.

【3】Inspiration to solve a difficult problem will most probably come to us______.

A. when we get up in the morning

B. when we are tired in the evening

C. when we are full of energy in the late morning

D. when we are asleep at night

【4】 Which of the following can be the suitable title for the passage?

A. What is natural body rhythm?

B. Natural body rhythm is good for us.

【4】C

【解析】

試題分析:這篇文章講的是生物鐘，先簡單介紹了一下生物鐘，然后講人們應該好好的利用生物鐘。破壞生物鐘可能會對人的身體帶來問題。接著講了生物鐘在不同的時刻對人們的身體有著不同的影響力。

【1】A細節(jié)理解題。根據(jù)Paying attention to it can help us choose the suitable time of the day when we best perform specific tasks.可知注意生物鐘能夠幫助我們在一天中選擇最合適的事件做特殊的任務。故選A。

【2】D細節(jié)理解題。根據(jù)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.可知破壞生物鐘可能會導致很多問題，比如壓抑、肥胖或者頭疼。這只是說有可能，但不是必然的，D選項太過武斷。故選D。

【3】B細節(jié)理解題。根據(jù)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，對一個成年人來說，當他們晚上疲憊的時候反而能完美的解決復雜的問題。故選B。

【4】C主旨大意題。這篇文章講的是生物鐘，先簡單介紹了一下生物鐘，然后講人們應該好好的利用生物鐘。破壞生物鐘可能會對人的身體帶來問題。接著講了生物鐘在不同的時刻對人們的身體有著不同的影響力。所以綜合來講，這篇文章講的是生物鐘與人們的健康。故選C。
