Last year， researchers published new findings from the Women"s Health Initiative， a long-term study of more than 160000midlife women. The data showed that multivitamin-takers are no（26）than those who don"t take the pills， at least when it comes to the big diseases——cancer， heart disease， and（27） "Even women with poor diets weren"t helped by taking amultivitamin，" says the study author Marian Neuhouser， PhD， in the cancer（28）program at the Fred Hutchinson CancerResearch Center， in Seattle. Vitamin（29）came into fashion in the early 1900s， when it was difficult or impossible for most people to get a wide variety of fresh fruits and vegetables. Back then， vitamin-deficiency diseases weren"t unheard-of: the bowed legs and（30）ribs caused by a severe shortage of vitamin D， or the skin problems and mental confusion caused by a lack of vitamin B， But these days， you"re（31）unlikely to be seriously deficient if you eat an average diet， if only because many packaged foods are vitamin-enriched. Sure， most of us could do with a couple more daily（32）of produce， but a multivitamin doesn"t do a good job at（33）those. "Multivitamins have maybe two dozen（34）but plans，s have hundreds of other useful compounds，"Neuhouser says. "If you just take a multivitamin， you"re missing lots of compounds that may be providing benefits. " There is onegroup that probably ought to keep taking a multivitamin: women of reproductive age. The supplement is insurance（35）pregnancy.

听音频，回答题

Have you ever noticed that while it"s pretty easy to tell your dog is sick， it"s much harder to know how your cat or bird are feeling？ Welt， before you start asking your dog why it can"t be more 26 like animals half its size， it"s probably worth 27 each animal"s place in the food chain. You see， the lower down the food chain you are， the more important it is for you to hide any sign of illness. Obvious illness or pain28 as red flags for predators. You may as well wear a sign saying， "Easy meal， guys. Come and get me."

Now， even small dogs are 29 programmed to function like predators，which 30 considering they are close relatives of wolves. And birds——you can probably 31 why the only way you"d find out your bird is sick is when it dies.

The situation with cats，32 dogs and birds， is much more interesting. On the one hand， cats are predators， but on the other， they"re small enough to be prey.

So how can you tell if your smaller pets need 33 attention？ For one thing，trust your feelings. No one knows your pets like you do， so if you notice even very 34 changes in habits and behavior， you may want to have a vet look them over. For a cat， other signs of illness might be that it has stopped grooming， is losing weight，35more or less than usual， or missing the litter box.

根据以下材料，回答题

More Than a Ride to School

The National Education Association claims "The school bus is a mirror Of the community."

They further add that， unfortunately， what appears on the exterior（外部）does not always reflect the reality of a chosen community. They are right， and sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl.

Bruce Hardy， school bus driver for Althouse Bus Company has been Liesl"s bus driver since kindergarten. Last year when Liesl"s family moved to Parkesburg， knowing her bus went by her new residence， she requested to ride the same bus.

This year Liesl is a senior and will enjoy her last year tiding the bus. She says， "It"s been a great tide so far! My bus driver is so cool and has always been a good friend and a good listener.

Sometimes when you"re a child， adults do not think that what you have to say is important. Mr.

Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfc agree.

Brace Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Transportation. Company President Larry Althouse acknowledges Bruce Hardy"s outstanding record. "You do not come by employees like Bruce these days: he has never missed a day of work and has a perfect driving record. Recognized in 2000 by the Pennsylvania School Bus Association for driving 350，000 accident free miles， Hardy"s reputation is made further evident through the relationships he has made with the students that ride

his bus. "

Althouse further added. "Althouse Bus Transportation was established 70 years ago and has been providing quality transportation ever since my grandfather started the business with one bus.

Althouse Bus Transportation is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come."

Three generations of business is not all the company has enjoyed. Thanks to divers like Bruce Hardy， they have been building relationships through generations. Liesl"s mother Carol also enjoys fond memories of riding Bruce Hardy"s bus to the Octorara School District.

The word "mirror"in the first line could be best replaced by__________. 查看材料

A."vehicle"

B."device"

C."need"

D."reflection"

There is an effect that not only have we all witnessed， but have26. Haven"t we all been on an elevator and noticed that just about everyone stops talking when they get on？ Why do we do that？ You can be having a 27 pleasant conversation with someone， and as soon as you get on an elevator， you just feel like you"d better shut up.

Then， as soon as the doors open， everyone28conversation. Primatologists， or people who study primate （灵长类动物） behavior， have a term for this. It"s called the "elevator effect，" though it doesn"t 29 only on elevators. It happens whenever a group of primates， like humans， is 30 a situation where escape is 31 impossible. It"s thought to be a kind of safety32: as long as nobody talks， nobody is going to risk getting in a fight when there"s no way to spread out. The elevator effect keeps a lid on potential problems before they start.

Even though they rarely if ever ride elevators， chimpanzees demonstrate the elevator effect as well. When chimps are temporarily crowded together into small areas， they will 33 their vocal communication， that is， nobody speaks， and avoid eye 34. The amount of scratching the chimps do， however， goes up. Since scratching is a sign of stress in chimps， we can imagine what they are feeling. It"s just like what we feel in a crowded elevator——everybody carefully35 the lighted numbers and no one saying a thing.
