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.

Isaac Newton, the great British scientist, is often so deep in his thoughts that he will forget to eat his dinner.

One day his friend came to have dinner with him. Dinner was put on the table but Newton didn't come out of his study（书房）. His friend sat down and waited for him. After waiting for quite a long time, he decided that Newton must be so deep in some new theory that he forgot all about the dinner. So he began to eat the chicken without Newton.

When he finished, he thought he would play a joke on his friend. He put all the chicken bones（骨头）back on the dish and covered them with the dish over. Then he left Newton's house. He was quite certain that his joke would work.

Several hours later, Newton came out of his study, feeling very hungry. He saw the table was ready for dinner and so he sat down. When he lifted the cover and saw the bones of the chicken, he was greatly surprised. He turned, looked at the clock, and saw that it was long past his usual time for dinner.

"Well, well," he said to himself, "I thought I ate nothing, but I am wrong." He got up from table and went back to his study and began to work again.

Judge the following statements True (T) or False (F).

1.Newton comes from America.

2.Newton's friend didn't have dinner with him.

3.Newton's friend put all the chicken bones back on the dish.

4.Several days later, Newton came out of his study.

5.Newton has eaten the chicken.
