What’s on Your Pet’s Mind? In 1977, Irene Pepperberg of Harvard University began studying what was on another creature’s mind by talking to it.Her first experiments began with Alex.Alex was a one year old African grey parrot and Irene taught him to produce the sounds of the English language.“I thought if he learned to communicate, I could ask him questions about how he sees the world.”

At the time, most scientists didn’t believe animals had any thoughts.They thought animals were more like robots but didn’t have the ability to think or feel.Of course, if you own a pet you probably disagree.But it is the job of a scientist to prove this and nowadays more scientists accept that animals can think for themselves.

“That’s why I started my studies with Alex,” Irene said, “Some people actually called me crazy for trying this.”

Nowadays, we have more and more evidence that animals have all sorts of mental abilities.Sheep can recognize faces.Chimpanzees (黑猩猩) use a variety of tools and even use weapons to hunt.And Alex the parrot became a very good talker.

Thirty years after the Alex studies began.Irene was still giving him English lessons up until his recent death.For example, if Alex was hungry he could say “want grape”.Alex could count to six and was learning the sounds for seven and eight.“He has to hear the words over and over before he can correctly say them.” Irene said, after pronouncing “seven” for Alex a few times in a row.Alex could also tell the difference between colors, shapes, sizes, and materials (e.g.wood and metal).Before he finally died, Alex managed to say “seven”.

Another famous pet that proved some animals have greater mental skills was a dog called Rico.He appeared on a German TV game show in 2011.Rico knew the names of 200 different toys and easily learned the names of new ones.When Rico became famous, many other dog owners wanted to show how clever their pets were.Another dog called Betsy could understand 300 words.

One theory for dogs’ ability to learn a language is that they have ben close companions to humans for many centuries and so their ability to understand us is constantly evolving (进化).While animals can’t do what humans do yet, some scientists believe that examples like Alex and Rico prove that evolution develops intelligence, as well as physical appearance.

House Sitting

In many countries of the world people do what is called house sitting.It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel.After people retire, they might buy a van and travel all over the country.1.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy.House sitters might have to care for pets.Also, quite a few people have swimming pools in their back yard and they need cleaning.2. I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

3. There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter.You must be a trusted person, so that the home owner knows you will not steal anything.You must be able to go when the house owner wants you to go, so you need lots of free time.4.You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the house owner have a short holiday.Sometimes it is for much longer.We have had one house sit for six months, while the home owner travelled to Europe.

5. Then you can travel to many different countries and stay there.One of the important things to get are references from the home owners where you have stayed.A reference is a written letter to say that you are trustworthy and have looked after their home well.You can show these letters to prospective house sitting jobs and they know you will do a good job.

As I pulled into the parking lot of the to get a newspaper, I noticed a young man in a wheelchair who seemed to be with his wheelchair.“I’m sure he’s all right”, I thought, “or if he’s not, someone else will help him.”

by the customers and cars that were passing him by, I guessed they were thinking the thing.I got out and walked over to see what the was.

“Is there anything I can do?” I asked.I noticed he wasn’t able to , and was still struggling with the wheelchair.

I at the wheelchair and noticed that the clamp(夹锁) holding the electronic keyboard and chair controls had loosened, causing the equipment to slip down, out of his reach.

I pulled it back into .His hand pulled over to the keyboard and he hit a single key.An electronic voice said, “Thank you.”

A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content, but new research suggests a glass a day could form part of a diet.Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight.

A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain”.The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that current data do not clearly indicate if moderate drinking increases weight.

Boston University’s Dr.Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病),which relate to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.

The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.

For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese.What’s more, a study three years ago suggested that reveratrol, a compound present in grapes and red wine, destroys fat cells.
