Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

Given that many people’s moods (情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates.Its founder is Chris Lee who grew up at his parents' comer store with one hand almost always in the jar of sweets.

If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored(味道)chocolates.

The CRF's produce is "green" made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The Exotic Series一with Sichuan pepper, red bean (豆).cheese and other flavors一also does well and is fun to taste. And for chocolate snobs,who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.

Dear Dr.Servaas,

I was diagnosed with histoplasrnosis(组织胞浆菌病)30 years ago .At that time, my doctor told me that it was lung fungus(真菌)that could affect my eyesight.This has happened·Can it affect other organs of the body?

F.Buongiorne

Delta Junction,Arkansas,

Most people have no symptoms resulting from the lung infection,explains histo expert Dr.L.Joseph Wheat,when symptoms do develop,they are usually mild and will disappear without treatment

In some cases,however,histo can spread from the lungs and cause more serious problems.

“Histo is more severe in persons with diseases that reduce thcir immunity or who are receiving immunosuppressive(免疫抑制)medications,”says Dr.Wheat,"In such cases,histo can spread from lungs to other parts of the body.Patients with this type of histoplasmosis usually have constant fever,sweats,and weight loss·Excellent tests are available to diagnose this type of histo,and the treatment is highly effective·”

As mentioned by our Arkansas reader,eye problems accompanied by vision loss have been reported long after the first infection.

"Histo is thought by some to be a cause of spots on the back of the eye,called ‘histo spots’,”notes Dr·Wheat.“These injuries cause no problems in some patients, while in others they cause visual loss.There is no proof that histo causes these spots, however,as the organism is not found in the injured parts,and treatment for histo is not effective for the eye spots.”

People catch histoplasmosis by breathing extremely small spores(孢子)of the histoplasma fungus into their lungs·This fungus is commonly found in areas polluted by bird or bat droppings such as caves,chicken cages,barns(谷仓),and under bridges.It will spread through the air during construction or whenever plowing,sweeping,or digging disturbs the soil.

B.The disease will make people put on weight.

C.The disease won’t cause serious problems and no medicine is effective for it·

D.The disease doesn’t,t necessarily have a serious effect on every patient with it·

3.How is“histo" related to“histo spots"?

B.Patients with“histo" will have“histo spots".

C."Histo spots" will cause visual loss to all patients.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Our oldest daughter is having trouble letting go of an old red sofa.

It’s not the sofa she’s having trouble letting go of as much as the memories.It was their first sofa.It has been loaded and unloaded onto moving trucks seven times.Three kids have eaten on it,dripped on it,and jumped on it.

Yet she’s having a hard time letting go and asked if I thought that was strange.

“Completely,” I said.“You get it from me.”

When we were ready to get rid of our baby things,I sold our crib (婴儿床) at the neighborhood garage sale.I had pieces of it in the garage and the other pieces of it still in the house.A young woman said she wanted to buy it.

My throat tightened and the tears began to well.She pulled out cash and I cheered up.

But by the time I returned with the other pieces to the crib,I was all sobbing.“Have you considered that maybe you’re not ready to sell it?” the woman asked.

“No-o-o-o,” I cried.“It’s fine,really,” I said.“Take it.”

Our attachment to stuff grows in direct relationship to the amount of time it has sat in one place.The longer it sits,the harder it is to get rid of it.You think: “Hey,we’ve hung onto it this long – it must be valuable!” As though yellowing and a layer of dust increase value.

People who find it extremely hard to part with things have been made into entertainment in a television show called Hoarders.If an episode (集) of that isn’t depressing enough for you,producers now offer Extreme Hoarders.Both of which are not to be outdone by Storage Wars,a show about aggressive people who bid on other people’s storage units.

Let the sofa go,I told my daughter.It served its purpose.You can get a new one.Give the kids some crackers (饼干) and juice and it will be like the old one in six weeks.
