And now researchers from Brown University in Rhode Island think they know why. They found that one-half of the brain “remains more 7.(清醒的)” 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 reported they had a harder time sleeping the first night at a hotel or other places 8.(外面) their home. They call it “first-night 9.(影响)”. “In Japan they say, If you change your bed, you cant sleep,” said Yuka Sasaki, one of the reports 10.(作者). “You dont sleep very well in a new place. We all know about it.”The researchers measured brain waves for 35 volunteers over two nights in a 11.(实验室). The two nights were a week apart. They found during the first night the left half of the brain was more 12.(积极的) than the right half. This was during the first deep-sleep period, the researchers said.Sasaki said a lot of 13.(问题) remain. Researchers did not keep measuring brain waves all night long. So, they dont know if the left half keeps “watch” all night, or 14.(是否) 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 15.(结果) 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.参考答案A()1.although2.complete3.straight 4.history5.except()6.books7.information8.another 9.build/make/create10.cheap11.stores/shops 12.sell13.communicate14.surfing15.youngB()1.except2.helpful3.courage4.really 5.remains()6.trouble7.awake8.outside 9.influence10.writers11.laboratory/lab12.active13.questions14.whether/if 15.result
