Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.

Dr. Scott Small is a professor of neurology at Columbia University in new York City He is the lead writer 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 made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects 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 memorytests.

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 lead researcher of a four .year study involving 18,000 adults. This study will use flavones capsules(膠囊) The study subjects 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

Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 person would have to eat a huge amount of chocolate to get the same level of flavones given to the Lest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarity, Dr. says a cocoa-based flavones extract(提取)may be developed in the future But he says that more studies are needed to see how much flavones is good for our health

A. They were asked to take a high-level flavones drink

B. They were given capsules containing flavones

C. They were given brain imaging and memory tests

D. They were asked to take two pills of flavones capsules per day

2.What's the similarity of the 2 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. The subjects are divided into two groups in both experiments

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

A. To prove the first experiment is wrong

B. To carry out the experiment further

C. To test how much flavones can improve our memory.

D. To show eating chocolate is better to improve memory.

4.What can we learn from the last paragraph?

科目:高中英語 來源:2014-2015學年河南三門峽市高三第五次月考英語試卷(解析版) 題型:閱讀理解

Both of Jessica’s parents were lawyers and expected her to follow suit. So she went to law school, got a job at a great firm in Washington, DC, and worked as a lawyer for a decade. But her heart was never in it. “I had a big salary but no personal satisfaction,” she says.

Jessica found pleasure in the same thing that had brought her joy since joining the church choir at the age of 12. “Singing always felt like communicating something real at a spiritual and emotional level,” says Jessica. Yet she never considered it a career option. “That seemed like something people did in fairy tales, and I would never let my parents down,” she says.

It was her mom’s diagnosis of brain cancer in 2009 that made Jessica realize she had to write her own happy-ever-after. “Work was busy and my mother was ailing. So I was flying back and forth from Washington, DC to Houston to see her,” Jessica says. “I finally said, ‘Enough!’ and quit.” While caring for her mom, Jessica made a plan. She would spend her savings and study music for a year, and then open a part-time law practice so she could pursue her passion. Before her mother passed away two years later, she encouraged Jessica to follow her dream. Her song Live This Life was inspired by her mom, and her dad came to watch her perform at clubs.

In 2012, Jessica moved to Nashville to try singing and songwriting. A decade of presenting cases in court gave her the confidence to sing for a crowd. “At 20, I would have been too shy to perform,” says Jessica.

“Doing music is so free,” Jessica says. “There’s no pressure to be a star. Success, to me, isn’t a dollar amount or a record deal; it’s doing what I love.”

1.Which of the following is TRUE?

A. Jessica wasn’t satisfied with the pay she got as a lawyer.

B. Jessica didn’t know what she truly loved for ten years.
