【题目】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.

【题目】

The world’s longest cross-sea bridge --- the Hong Kong-Zhuhai-Macao Bridge, opened to public traffic at 9 a.m. on October 24. The 55-km-long bridge links(连接) China’s Hong Kong Special Administrative Region (SAR). Zhuhai City of Guangdong Province and Macao SAR (澳门特别行政区).

The bridge’s construction began in December 2009 and finished in February 2018. The bridge looks like a “Y”. It can cut travel time between Hong Kong and Zhuhai from three hours to just 30 minutes. This will greatly cut down the cost and time of transportation between the mainland and Hong Kong.

We should know that the bridge adopts ( 采取) the right-hand traffic rules of the mainland, and changes into left-hand rules after the vehicles arrive at the Hong Kong or Macao ports(港口). Vehicles such as cars, buses and so on should pay the road toll( 通行费). People can pay the toll through ETC or Hong Kong express. Travelers can also pay by using Alipay, WeChat or RMB.

“In the next step, we should be more careful about how to make the two islands more beautiful and have more travelers,” one of the greatest designers, 93-year-old professor Sun said.

1How long does it take to build the Hong Kong-Zhuhai-Macao Bridge?

A.About 5 years.B.More than 8 years.C.Over 10 years.

2How much time do we spend travelling from Zhuhai to Hong Kong through the bridge now?

A.3 hours.B.3.5 hours.C.30 minutes.

3What does the underlined word “vehicles” mean?

A.卡车B.交通工具C.高铁

4Which of the following is TRUE?

A.The world’s longest cross-set bridge opened to public traffic at 9 p.m on October 24.

B.People can pay the road toll through different ways.

C.Drivers needn’t to follow right-drive traffic rules of the mainland.

5Where can we probably find this passage?

A.In a newspaper.B.In a magazine.C.In a short story.
