Monitoring the mood of a pet dog could be used as an early warning sign that an elderly owner is struggling to cope, a new report has claimed.

Researchers placed movement sensors (探测器) on dogs to track their behaviour and identified 17 distinct activities, including chewing, barking, sitting and digging.

This allowed them to map the normal behaviour of a healthy, happy dog, which means any changes can be monitored and could indicate an issue with their owner.

Nils Hammerla, part of the team from Newcastle University, said, “Humans and dogs have lived together in close relationships for thousands of years, which has led to strong emotional and social mutual bonds.”

“A dog’s physical and emotional dependence on their owner means that their well-being is likely to reflect that of their owner. Any changes such as the dog being walked less often, perhaps not being fed regularly, or simply demonstrating “unhappy” behaviour could be an early indicator for families that an older relative needs help. This is the first system of its kind which allows us to remotely monitor a dog’s behaviour in its natural setting.”

The team of academics, who presented their findings at the 2013 UbiComp conference in Zurich, created a hi-tech, waterproof (防水的) dog collar for the study.

Dr Cas Ladha, who led the study, said: “A lot of our research is focused on developing intelligent systems that can help older people to live independently for longer. But developing a system that reassures family and carers that an older relative is well without intruding on (侵犯) the individual’s privacy is difficult. This is just the first step but the idea behind this research is that it would allow us to support people without the need for cameras.”

A range of dogs was used for the study, as the team needed to map distinct behaviours that correlated between different breeds.

C. warn D. recognize

3.Which of the following is an advantage of the intelligent system mentioned in the text?

A. It can indicate that people aren’t well.

B. It can identify different activities of dogs.

C. It monitors an elderly owner without disturbing his privacy.

D. It lets people see the dog’s behavior clearly.

4.Which of the following could be the best title for the text?

A. Dogs’ mood can be an indicator of owners’ health

Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill.

In the study,99 college students between the ages of 18 and 30 each spent an hour on a compute, trying to get through a virtual maze(迷宫).The maze was different place each time they tired—making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.

For the first 90 minutes of a five-hour break, half of the participants stayed awake and an half were told to take a short nap .Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after sleep—and they were awakened within a minute of sleep to describe their dreams.

Stickgold, a neuroscientist(神经科学家),wanted to know what people were dreaming about when their eyes weren't moving during sleep.

Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working ; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.

Stickgold suggests the dream itself doesn‘t help a person learn—it's the other way around.He suspects that the dream was caused by the brain processes associated with learning.

All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn't take a nap, didn't show the same improvement.

1.Before having a short nap, participants of the experiment were asked to .

A. stay in a different place in the maze

B. design a virtual maze which is difficult to get through

C. experience the experiment and try to remember something

D. get through a virtual maze on a computer from the same place

2.What can we learn from the text?

A. Participants who took a nap were required to express their thoughts.

B. Some dreams may encourage people to invent something new.

C. Participants who dreamed about films could finish the task more easily.

D. Participants whose dreams had something to do with the maze could find the tree faster.

3.According to Stickgold, .

A. every person may dream about what they learned

B. people's brain processes may still be connected with their learning in their dreams

C. once people's eyes stop moving, they are sure to dream about something

D. no matter how fantastical or boring, dreams are connected with people's life

4.What is the best title for this text?

A. Dreams Are Strange B. Not All Dreams Are True

C. Dreaming Makes Perfect D. Stickgold, a Dream Expert
