Question

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

The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today's fast-paced modem 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 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 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】C

【2】B

【3】A

【4】D

【5】C

【解析】

試題分析: 人體生物鐘的存在對我們來說有著極重要的意義，如果外界環(huán)境變化干擾了時鐘的正常運轉，造成了人體器官內(nèi)部節(jié)奏的紊亂，會引起某些疾病；而如果能夠合理利用生物鐘的規(guī)律人們就能高效地完成某些任務。

【1】C。主旨大意題。文章開頭提出人們要注意人體的生物鐘以便能更好的選對我們做某些特殊工作的最佳時間，然后在下文對此進行詳細講述，由此判斷文章中心內(nèi)容就是關于生物鐘的，故選C。

【2】B詞義猜測題。從上文內(nèi)容可知注意人體的生物鐘并按照規(guī)律去做事會對健康有益，而后句內(nèi)容則說明的是人體會出現(xiàn)的問題，由此推斷不遵從人體生物鐘則會出現(xiàn)很多健康問題，故判斷該詞意為“破壞，擾亂”，選B。

【3】A細節(jié)理解題。從第八段Surprisingly, tiredness may increase our creative powers可知選A。根據(jù)首段natural body rhythm influences our energy and alertness可知C選項錯誤；根據(jù)第六段Most of us are more easily distracted between noon and 4 pm可知B選項錯誤；從第五段most adults perform best in the late morning判斷D選項錯誤。

【4】D細節(jié)理解題。根據(jù)文章末段not everyone's body clock is the same可知不是每個人的生物鐘都一樣，故選D。根據(jù)第五段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可知人體記憶力和注意力是隨著體溫的上升而增強，故A選項錯誤。而根據(jù)第七段sleepiness tends to peak around 2 pm，making that a good time for a nap判斷B選項錯誤。根據(jù)倒數(shù)第二段Physical performance is usually best from about 3 to 6 pm判斷C選項錯誤。

【5】 C細節(jié)理解題。從文章首段Paying attention to it can help us choose the suitable time of day when we best perform specific tasks可知答案選C。
