Question

请阅读下面短文，从每小题所给的A、B、C三个选项中选出一个最佳选项，并将答案填写到答题卷的相应位置上

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 (华尔街日报).

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

Between noon and 4 pm, people begin to get distracted. 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.

【解析】

本文主要是讲述有关生物钟的事情。如果我们按照生物钟安排作息，会事半功倍。比如下午三点到六点是最佳的运动时间。

1.细节理解题。根据文中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.说到人脑，许多人在早上晚些时候工作得最好。这是因为身体的温度需要一天的时间来升高。当你醒来时洗个热水澡有助于加快这个过程。可知人体的温度需要时间来升高，故选C。

2.细节理解题。根据文中Evening people will wake later but their brain will work better toward the end of the day.晚上醒来的人会晚些，但他们的大脑在一天结束时会工作得更好。可知晚上醒来的人们最好晚一点醒来，晚上工作的会更好，故选B。

3.词义猜测题。根据后文This is partly because our brain becomes less alert after we eat a big meal.这在一定程度上是因为我们吃了大餐后大脑变得不那么清醒。可知，前面distracted指的是“注意力分散的”，故选B。

4.细节理解题。根据文中Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day.身体表现在下午3点到6点之间是最好的，所以在白天晚些时候锻炼更好。可知A项正确；根据文中because our brain becomes less alert after we eat a big meal.因为我们吃了大餐后大脑变得不那么清醒。可知B错误；C选项在文中并没有提到，所以排除；故选A。

5.最佳标题题。根据文中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 (华尔街日报).很多研究表明我们应该注意我们的生物钟。据《华尔街日报》报道，它可以告诉我们一天中我们最有能力表现的时间。可知，主要是说做事情的最佳时机，故选C。
