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, tea and 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 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 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 lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsules. 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（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 flavones from their chocolate products. Similarly, Dr. Manson 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.
1.What was done to the subjects 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.
2.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. The subjects are divided into two groups in both experiments.
3.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.
4.What can we learn from the 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 health will be.
D. It's easy for people to get the same level of flavones given to the test subjects.

A typical lion tamer（驯兽师）in people’s mind is an entertainer holding a whip( 鞭) at a chair. The whip gets all of the attention, but it’s mostly for show. In reality, it’s the chair that does the important work. When a lion tamer holds a chair in front of the lion’s face, the lion tries to focus on all four legs of the chair at the same time. With its focus divided, the lion becomes confused and is unsure about what to do next. When faced with so many options, the lion chooses to freeze and wait instead of attacking the man holding the chair.
How often do you find yourself in the same position as the lion? How often do you have something you want to achieve (e.g. lose weight, start a business, travel more)—only to end up confused by all of the options in front of you and never make progress?
This upsets me to no end because while all the experts are busy debating about which option is best, the people who want to improve their lives are left confused by all of the conflicting information. The end result is that we feel like we can’t focus or that we’re focused on the wrong things, and so we take less action, make less progress, and stay the same when we could be improving.
It doesn’t have to be that way. Anytime you find the world waving a chair in your face, remember this: All you need to do is focus on one thing. You just need to get started. Starting before you feel ready is one of the habits of successful people. If you have somewhere you want to go, something you want to accomplish, someone you want to become…take immediate action. If you’re clear about where you want to go, the rest of the world will either help you get there or get out of the way.
1.Why does the lion tamer use a chair?
A. To entertain the audience.
B. To show off his skills.
C. To get ready for a fight.
D. To trick the lion.
2.In what sense are people similar to a lion facing a chair?
A. They feel puzzled over choices.
B. They hold on to the wrong things.
C. They find it hard to make changes.
D. They have to do something for show
3.What is the author’s attitude towards the expert mentioned in Paragraph3?
A. Tolerant. B. Doubtful.
C. Respectful. D. Supportive.
4.When the world is “waving a chair in your face”, you’re advised to _____
A. wait for a better chance
B. break your old habits
C. make a quick decision
D. ask for clear guidance

One year ago, I was in great trouble. I work hard at English and devoted all my spare time to practise it. But I failed to pass the mid-term exam, which made me great disappointed. So I asked my grandpa for advice when I got to home. Hearing that I told him, he said, “To some extent, exam results sometime can’t truly reflect your ability. You can’t judge your progress by one examination.” He encouraged myself to work hard for long time to check my results. I took my grandpa’s advice. Now my English is much better than ago. From my experience, I feel that we should listen to opinion from old people.

When I was growing up, I had an old neighbor named Doctor Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard, but was always very kind.
When Doctor Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest. He had some interesting theories about planting trees. He hardly watered his new trees, which flew in the face of conventional wisdom. Once I asked why and he told me that watering plants spoiled the
m because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of wateri
ng his trees every morning, he’d beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I’d watched him plant some twenty five years ago. They were all tall, big and robust since they have deep roots now.
I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity(逆境) seemed to benefit Doctor Gibb’s trees in ways comfort and ease never could.
Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to meet with hardship. There’s always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won’t be torn apart.
1.With the trees planted, Doctor Gibbs __________
A. kept watering them every morning
B. paid little attention to them
C. talked to them to get their attention
D. beat them to make them grow deep roots
2.The underlined word “robust” in para.3 probably means _________?
A. strange B. deep C. strong D. old
3. Which of the following will be the author’s prayer on the days ahead?
A. Have an easy life, without too much to worry about.
B. Meet people like Dr. Gibbs in the future.
C. Have good luck, encountering less hardship in their life.
D. Be able to stand the rain and wind in their lives.
4.Which of the following can be the best title of the passage?
A. Growing roots
B. Doctor Gibbs and his trees
C. Prayers for my sons
D. Watering trees

Exploit your parking space

A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.
Use your roof
