Today, calcium shortage is one of the main concerns of women in their 30s or even early 20s. The great fear is that when we reach our 50s or 60s, osteoprosis(骨质疏松症)will set in. That is why you can see a lot of advertisements for products supposedly containing a lot of calcium.
Because calcium is not that easy to acquire from the food we normally eat, busy women these days should take calcium supplements(补充物). There are a lot of different forms of these---calcium carbonate(碳酸钙),oyster(牡蛎)shell or bone-meal-based calcium supplements.
You have to be careful when choosing which kind to take. This is because calcium is not easily absorbed by the body. So the fact that you are taking supplements doesn’t mean that the body is actually benefiting from them. Different supplements may have different instructions on dosage(剂量)and manner of intake. You can ask your doctor to help you determine which supplement is the best for your needs.

C.We can’t get enough calcium only from food we eat every day |
D.Women as young as their 20s should be concerned about calcium shortage |
A.Honestly | B.Frankly | C.Secretly | D.Curiously |
A.what one chooses as a calcium supplement might not work |

British and Canadian experts say drugs could attack the parasite(寄生虫) causing the illness.They say the drug could be ready for human medical test in about 18 months.
The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system.It has similar symptoms(症状) to malaria(疟疾), making it difficult to diagnose.Left untreated, it moves to the brain, resulting in mental confusion and final death
The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies.
Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases."
He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease.
The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection.
The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada.The two drugs currently available to treat sleeping sickness both have problems.One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said.
小题1:The word backedin the last paragraph probably means_____.
A.conducted | B.supported | C.believed | D.managed |
A.about 60000 people died of the disease each year |
B.about 60000 people were cured of the disease each year |
C.600 million people are likely to get infected |
D.the disease is spreading fast in Africa |
A.in the journal Nature |
B.in a newspaper of the University of Dundee |
C.in a book about flies |
D.in a newspaper about medicine |
A.big drug companies play an important role in the research of the new drug |
B.people who get infected with the disease are mentally disturbed |
C.among 200 people infected with the disease, 5 may die because of the old drug |
D.Professor Paul Wyatt may be a professor at the University of York |
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤).They said that they found faults in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen.As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
小题1:People with fair skin and freckles .
A.seldom use sunscreen |
B.are more in danger of skin cancer |
C.can be free from the harm of the sun |
D.often expose themselves to the sun |
A.sunscreen users get skin cancer more often |
B.the volunteers have proved the effect of sunscreen |
C.the new study was based on the experiences of volunteers |
D.the number of skin cancer patients is increasing in America |
A.Sunscreen to Prevent Skin Cancer |
B.Sunscreen to Increase Skin Cancer |
C.Skin Cancer Caused by Sunscreen |
D.Skin Cancer Caused by Freckles |
“Grown-ups with music training in their childhood can have better memory for words,” said Dr Agnes Chan of the Chinese University of Hong Kong, who did the research. “They can remember things that you tell them better than those who did not have music training when they were young.”
It seems that one can remember spoken words because his brain has a special part. “That part of the brain is larger in musicians than in non-musicians,” Dr Chan told BBC. “If that part of the brain is larger, it may be better developed and so this explains very nicely our results.”
Dr Chan and her workmates came to their conclusion after studying students. Their research is reported in the latest edition of the journal(杂志) Nature. “We did the experiment with 60 girl college students from our university and 30 of them have at least six years training with one western musical instrument (such as the violin and the piano) before the age of 12. The other 30 had received no music training. We tested their memory by reading them some words and asking them to remember these words—a very common test for memory. We found that people who have had music training can remember about 70% more information than those who have not had any music training.”
Dr Chan thinks the process(过程) of learning is more important than the actual instrument used. She also believes if one is able to remember words through learning to play instruments, he or she could have some very real benefits. Dr Chan thinks this could be developed into a medical way for patients who are suffering from memory loss.
小题1: According to the writer, learning to play a musical instrument helps to ______.
A.get more knowledge |
B.live more happily |
C.remember more words |
D.make one become a musician |
A.Dr Chan thinks people should have music training when they grow up. |
B.Dr Chan thinks the special part of the brain doesn’t need developing. |
C.Dr Chan thinks people should have music training when they are young. |
D.Dr Chan thinks musicians have a larger brain than non-musicians. |
A.30 girl students. | B.60 girl students. |
C.17% of his students. | D.60 girl and boy students. |
At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.
Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.
There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.
What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!
小题1:The underlined phrase “bounce back ”means “__________.”
A.jump backward | B.run fast | C.prevent | D.recover |
A.teach people how to eat properly |
B.discover how important the exercise is to one’s health |
C.study the ways to slow or stop the process of aging |
D.invent new medicine to slow down the process of aging |
A.consider their lives have been very successful |
B.have come through the battle of life safely |
C.know more about themselves and the outside world |
D.can have a good rest and enjoy themselves |
A.Two | B.Four | C.Five | D.Six |
Sometimes we treat people from other countries unfairly, because one person from that culture did something bad.Well, has your class ever been punished just because a few kids were causing trouble? Has your whole family ever been blamed for something your little sister did? It doesn’t seem fair, does it? It’s just equally unfair to blame a whole culture for what two or three people have done.
So here are some things that you can do to help yourself understand other cultures:
①Find common ground!
Just remember that even though some people look different on the outside, that doesn’t change how they are on the inside.They still have the exact same feelings!
②________________
Because someone from another culture has been mean to you, you decide to avoid everyone from that culture.Well think about it.Why are you blaming them for something they didn’t have anything to do with? Put yourself in their shoes.How would you feel? Putting yourself inside someone else’s head can be a very powerful way to understand WHY they are acting the way they are.
③Try to make friends with people from other cultures!
You could ask them about their culture, or what it is like in their country, if they can remember, or if they have ever lived there.Try foods from their culture, or ask them about words in their language.You might be surprised at how interesting other cultures can be! You can join great discussion groups, participate in projects, and have lots of fun doing new things.
④Be aware that you’ve judged other people
If you know what you have done, it helps to make things better.Pay attention to what you think about other people.It helps.
小题1:What is mainly discussed in this passage?
A.Why there are differences between people |
B.What to do to understand other cultures |
C.How people feel when they meet people from other cultures |
