Question

【題目】【2016河南中考】閱讀理解。

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 (測量腦波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart (間隔). 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 (輪換) 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.

根據(jù)材料內(nèi)容選擇最佳答案，并將其標(biāo)號填入題前括號內(nèi)。

【4】A

【5】D

【解析】

試題分析：本文主要介紹了很多人在一個新地方睡不著的原因。研究人員通過對志愿者的測量發(fā)現(xiàn)在第一晚上左半腦比右半腦活躍。但是他們不知道為什么大腦的活動總是在左大腦上，這項研究是令人愉快的，因為我們知道我們的大腦在一個新地方看著我們。

【1】B推理判斷題。根據(jù)The researchers measured brain waves (測量腦波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart (間隔). 可知研究人員測量腦波在兩晚，這兩晚上相隔一周，故推斷研究人員對志愿者測量了兩次，故選B。

【2】D細(xì)節(jié)理解題。根據(jù)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間，左半腦比右半腦活躍，故選D。

【3】C細(xì)節(jié)理解題。根據(jù)They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.可知他們不知道為什么大腦的活動總是在左大腦上，故選C。

【4】A詞義猜測題。根據(jù)It is good to know that our brain is "looking out for us" in a new place. 可知研究人員知道我們的大腦在一個新地方看著我們，故這項研究是令人高興的，故選A。

【5】D概括歸納題。根據(jù)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. 可知本文主要介紹了為什么很多人在一個新地方睡不著的原因，故選D。
