Question

【题目】【2016河南中考】阅读理解。

Have you ever had trouble sleeping in a new place?

Lots of people do. And now researchers from Brown University in Rhode Island think they know why. They found that one-half of the brain "remains more awake" than the other half when people are trying to sleep in a new place.

The sleep findings were reported in Current Biology by Brown University. In their report, the researchers said many people report they have a harder time sleeping the first night at a hotel or other places outside their home. They call it "first-night influence". "In Japan they say, 'If you change your bed, you can't sleep,'" said Yuka Sasaki, one of the report's writers. "You don't sleep very well in a new place. We all know about it."

The researchers measured brain waves (测量脑波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart (间隔). They found during the first night the left half of the brain was more active than the right half. This was during the first deep-sleep period, the researchers said.

Sasaki said a lot of questions remain.

Researchers did not keep measuring brain waves all night long. So, they don't know if the left half keeps "watch" all night, or whether it "works in shifts (轮换) with the right half later in the night". They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.

For some, this research may be calming. It is good to know that our brain is "looking out for us" in a new place. But it may not help with sleep. That brain activity, at least according to this new research, makes it harder to get the sleep people need to wake up well rested in the morning.

【4】A

【5】D

【解析】

试题分析：本文主要介绍了很多人在一个新地方睡不着的原因。研究人员通过对志愿者的测量发现在第一晚上左半脑比右半脑活跃。但是他们不知道为什么大脑的活动总是在左大脑上，这项研究是令人愉快的，因为我们知道我们的大脑在一个新地方看着我们。

【1】B推理判断题。根据The researchers measured brain waves (测量脑波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart (间隔). 可知研究人员测量脑波在两晚，这两晚上相隔一周，故推断研究人员对志愿者测量了两次，故选B。

【2】D细节理解题。根据They found during the first night the left half of the brain was more active than the right half. This was during the first deep-sleep period, the researchers said.可知第一次深度睡眠期间，左半脑比右半脑活跃，故选D。

【3】C细节理解题。根据They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.可知他们不知道为什么大脑的活动总是在左大脑上，故选C。

【4】A词义猜测题。根据It is good to know that our brain is "looking out for us" in a new place. 可知研究人员知道我们的大脑在一个新地方看着我们，故这项研究是令人高兴的，故选A。

【5】D概括归纳题。根据Have you ever had trouble sleeping in a new place?Lots of people do. And now researchers from Brown University in Rhode Island think they know why. 可知本文主要介绍了为什么很多人在一个新地方睡不着的原因，故选D。
