Question

【題目】 What time of day do you feel most alert(清醒的)? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal.

When it comes to the human brain, many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help speed this up.

But everyone’s body clock is different. Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.

Research show that we’re better at some activities at certain times of the day. Physical performance is at its best between 3pm and 6pm, so it’s better to exercise later in the day.

Between noon and 4 pm, people begin to get distracted (思想不集中的). This is partly because our brain becomes less alert after we eat a big meal. Research also shows that we become sleepy around 2 pm.

Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high.

【1】Many people perform best later in the morning because________.

A.they can’t get up very early.B.they have to take a shower first.

C.the body’s temperature needs time to rise.D.that’s when the brain wakes up.

【2】Evening people had better _________.

A.rise early and work in the morning.B.wake later and work better in the evening.

C.rise late and work in the morningD.wake later and work after midnight.

【3】According to the research, which of the following is TRUE?

A.It’s better to do exercise in the afternoon.B.We perform better after eating a big meal.

C.Sleeping at 2 pm is not good for our health.D.Our body burns calories better at night.

【4】What would be the best title for the story?

A.Research about time.B.The best time to do things.

C.Brain performance.D.Different periods of a day.

Answer 1

【答案】

【1】C

【2】B

【3】A

【4】B

【解析】

本文是一篇說(shuō)明文。文章主要介紹人體生物鐘能夠顯示出人一天當(dāng)中什么時(shí)候表現(xiàn)最好，不同的人有不同的生物鐘，人們?cè)诓煌�的時(shí)間段身體活動(dòng)能力也不一樣。

【1】細(xì)節(jié)理解題。根據(jù)第二段“many people work best … takes time to rise through the day”可知，有些人在早上后半段表現(xiàn)更好，那是因?yàn)樾枰獣r(shí)間來(lái)升高體溫。故選C。

【2】細(xì)節(jié)理解題。根據(jù)“Evening people will… toward the end of the day. ”可知，習(xí)慣夜晚生物鐘的人起得遲，大腦在一天結(jié)束時(shí)更活躍。故選B。

【3】細(xì)節(jié)理解題。根據(jù)“Physical performance …exercise later in the day.”可知，鍛煉身體最好在下午3到6點(diǎn)，A正確；根據(jù)“our brain becomes less alert after we eat a big meal”可知，吃完飯之后大腦警覺性下降，B錯(cuò)誤；根據(jù)“Research also shows that we become sleepy around 2 pm.”可知，下午兩點(diǎn)我們會(huì)變得昏昏欲睡，并沒(méi)有說(shuō)是否適合睡覺，C錯(cuò)誤；根據(jù)最后一段“it is best to eat… from getting too high.”可知，在身體活躍時(shí)期吃東西有助于燃燒卡路里，D錯(cuò)誤。故選A。

【4】主旨大意題。本文主要介紹生物種對(duì)我們?nèi)梭w哪些活動(dòng)有影響，根據(jù)生物鐘，我們能夠更好掌握一天之中什么時(shí)候最適合做什么事，所以B正確。故選B。
