Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones(黄酮), substances found in cocoa,teaand some kinds of vegetables,may improve age-related memory failure.
Dr. Scott Small is a professor of neurology (神经学) at Columbia University in New York City. He is the leadwriter of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink madefrom cocoa beans or a low-level flavones drink. For a period of three months, somesubjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.
The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the leadresearcher of a four-year study involving 18,000 adults. This study will use flavones capsules. The studysubjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo(安慰剂).
Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 persons would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavonesfromtheir chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract(提取)maybe developed in the future But he says that more studies are needed to see how much flavones is good for our health.
What was done to thesubjects after Dr. Small's study?

A.They were asked to take a high-level flavones drink.
B.They were given brain imaging and memory tests.
C.They were given capsules containing flavones.
D.They were asked to take two pills of flavones capsules per day.

What's the similarity of the two experiments?

A.Both use high-level flavones capsules.
B.The number of the subjects is the same.
C.Drinks and placebos are used in both experiments.
D.Thesubjects are divided into two groups in both experiments.

Why will Dr. Manson carry out the four-year study?

A.To carry out the experiment further.
B.To prove the first experiment is wrong.
C.To test how much flavones can improve our memory.
D.To show eating chocolate is better to improve memory.

What can we learnfromthe last paragraph?

A.It's not necessary for us to eat chocolate.
B.In the future we can get flavones without eating chocolate.
C.The more we eat flavones, the better our healthwill be.
D.It's easy for people to get the same level of flavones given to the test subjects.

Most people want to know how things are made. They honestly admit, however, that they hardly know a thing when it comes to understanding how a piece of music is made. Where a composer (作曲家) begins, how he manages to keep going - in fact, how and where he leams his trade -all are covered in complete darkness. The composer, in short, is a man of mystery. (神秘).
One of the first things the common man wants to know about is the part inspiration (灵感) plays in a composer' s work. He finds it difficult to believe that composers are not much interested in that question. Writing music is as natural for the composer as eating or sleeping for all. Music is something that the composer happens to have been born for.
The composer, therefore, does not say to himself: "Do I feel inspired?" He says to himself:
"Do I feel like working today?" And if he feels like working, he does. It is more or less like saying to himself: "Do I feel sleepy?" If you feel sleepy, you go to sleep. If you don't feel sleepy, you stay up. If the composer doesn' t feel like working, he doesn' t work. It' s as simple as that.
What would be the best title for the text?

A.Composer: a man of mystery
B.Practice makes good music
C.Relation between sleeping and music
D.Music: product of nature

SANTO DOMINGO, Domincan Republic ---An infant girl born with a second head bled to death Saturday after complex surgery (外科手术) to remove her partially formed twin , her parents and doctors said.
A medical team completed the 11- hour operation Friday night and said 8-week-old Rebecca Martinez died seven hours later. Doctors had warned after the surgery that the girl would be at great risk of death.

Without an operation , Rebecca would have barely been able to lift her head at 3 months old. Her doctors said the pressure from the second head would have prevented her brain from developing.
“ We always saw Rebecca without the extra part of her body, ”er father said after her death.

My husband, Tom, is a born shopper. He loves to look at things and to touch them. He likes to compare prices between the same things in different stores. He would never think of buying anything without looking around in several stores. I, on the other hand, am not a shopper. I regard shopping as boring and unpleasant. If I like something and can afford it, I buy it immediately. I never take a time to look around for a good sale or a better deal (交易). Of course my husband and I never go shopping together. Doing shopping together would be too painful for both of us . When it comes to shopping, we go our separate ways.
Sometimes I ask my son Jimmy to buy some food in the shop not far from our home. But he is always absentminded. This was his story.
One day I said to him , “ I hope you won’t forget what I have told you to buy.” “No,” said Jimmy. “ I won’t forget . You want three organs, six eggs and a pound of meet.”
He went running down the street to the shop. As he ran , he said to himself over and over again , “ Three organs , six eggs and a pound of meat.”
In the beginning he remembered everything but he stopped several times. Once he saw two men fighting outside a clothes shop until a policeman stopped them. One of them was badly hurt. Then he stopped to give ten cents to a beggar. Then he met some of his friends and he played with them for a while. When he reached the shop, he had forgotten everything except six eggs.
As he walked home, his face became sadder and sadder. When he saw me he said, “ I’m sorry , mum . I have forgotten to buy oranges and the meat . I only remembered to buy six eggs , but I’ve dropped three of them.”
