Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans.Alan Beck,an expert in human-animal relationship,and Nancy Edwards,a professor of nursing,are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression,physical activity,and life satisfaction.“No one will argue that an older person is better off being more active,challenged,or stimulated(刺激),” Edwards points out.“The problem is how we promote that,especially for those without friends or help.A robotic dog could be a solution.”

In the study,the robot,called AIBO,is placed for six weeks in the homes of some old people who live alone.Before placing AIBO in the home,researchers will collect baseline data for six weeks.These old people will keep a diary to note their feelings and activities before and after AIBO.Then,the researchers will review the data to determine if it has inspired any changes in the life of its owner.

“I talk to him all the time,and he responds to my voice,”says a seventy-year-old lady.“When I’m watching TV,he’ll stay in my arms until he wants down.He has a mind of his own.”

The AIBOs respond to certain orders.The researchers say they have some advantages over live dogs,especially for old people.Often the elderly are disabled and cannot care for an animal by walking it or playing with it.A robotic dog removes exercise and feeding concerns.

“At the beginning,it was believed that no one would relate to the robotic dog because it was metal and not furry,” Beck says.“But it’s amazing how quickly we have given up that belief.”

“Hopefully,down the road,these robotic pets could become more valuable health helpers.They will record their masters’ blood pressure,oxygen levels,or heart rhythms.AIBOs may even one day have games that can help stimulate older people’s minds.”

1.The purpose of Beck and Edwards’ study is to .

A.understand human-animal relationship

B.find the causes of old people’s loneliness

C.make lonely old people’s life better

D.promote the animal-assisted research

2.In the research,the old people are asked to .

A.note the activities of AIBOs

B.keep AIBOs at home for 12 weeks

C.analyze the collected information

D.record their feelings and activities

3.What is the advantage of AIBOs over live dogs?

A.They can watch TV with their owners.

B.They can help the disabled people.

C.They respond to all the human orders.

D.They are easier to keep at home.

4.The author seems to suggest that the future robotic dogs may .

B.cure certain diseases

C.change people’s beliefs

D.look more like real dogs

Is it wrong to use someone else’s wireless(Wi-Fi) connection?Just recently,a man was arrested for doing just that.At that time,he was sitting in the street with a laptop(便攜式電腦)and using an unsecured(無安全保護措施)wireless connection to surf the Net.What do you think about this topic?Listen to the following different views on it.

For a start,if someone is using your Internet service or downloading,this will affect your speed of access or download limit.Also,it’s bad for Internet service providers.They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free.And finally,just imagine this:what if the person who is stealing your Internet connection is involved in an illegal activity?I think the police are totally right to arrest these criminals.

—by Sandra Wilkins

Basically,if the person who paid for the service still has everything they paid for,what’s the problem?It’s just like using the light from streetlamps to read your book,or watching someone else’s firework display.It’s not stealing.

Also,if you leave your wireless connection unsecured,then it is your own fault(過錯)if someone else uses it.Just as you wouldn’t leave your front door unlocked,or your car door open,neither should you leave your wireless connection open.By leaving your wireless connection open,you are inviting people to use it.Securing your wireless connection is as easy as clicking a few settings on your router(路由器).And finally,haven’t the police got more important crimes to solve?They’re always saying how they haven’t got the manpower to solve real issues.But this is just ridiculous(荒謬的).

—by James Hoarley

1.Why was the man mentioned in the first paragraph arrested?

A.For stealing someone’s laptop.

B.For surfing the Net in the street.

C.For using an Internet service without permission.

D.For destroying others’ wireless connection.

2.What does Sandra Wilkins think of people using others’ Internet service?

A.He thinks it is necessary sometimes.

B.He thinks it is unacceptable.

C.He thinks it requires good computer skills.

D.He thinks it is good for Internet service providers.

3.In James Hoarley’s opinion, .

A.Internet service should be improved

B.using others’ Internet service is not stealing at all

C.it is hard to secure one’s wireless connection

D.people should leave their wireless connection open

4.What would be the best title for the passage?

A.Wireless worries B.Wireless connection

C.Internet service D.Internet users

On holidays you’re likely to eat and overeat between family gatherings and office parties. 1. Here are some tips to help you enjoy holiday food without completely changing your diet:

1.Switch to small plates.

Not only do smaller dishes fill up faster,but the same size help look like more food when it’s on a small dish. 2. But whatever the size of your plate,it’s most important to remember to keep it balanced:half for vegetables,a quarter for grains and a quarter for lean meat.

2.Measure out snakes

Your favorite holiday movie is on.Take a minute to check the nutrition label(標簽)and measure out a serving to keep calories in check.Take one popular brand of buttered microwave popcorn for example. 3. But the bag contains 2.5 servings.Eat the whole thing on your own,and you’ll have eaten 425 calories.

3.Split an entree(主菜).

Many restaurants serve far more food than one person needs in a single meal. 4. Or pack half your entree to go as soon as it’s served.Or choose a small-size option,if available.

4.Stop eating when you feel satisfied.

You don’t have to feel too full,or force yourself to clean your plate before putting down your fork. 5. When you’re satisfied,save the rest for leftovers.

A.Share a main dish with a friend.

B.It’s important for you to eat more on holidays.

C.Eat slowly and pay attention to feelings of hunger.

D.Studies show we tend to put on a few pounds this time of year.

E.Enjoy an entree slowly by yourself.

F.So you’ll be likely to serve yourself less.

G.One serving is about 4 cups popped with 170 calories.
