Psychology says that many are unwilling to take risks. It’s human nature to be nervous about putting ourselves on the line, whether physically or emotionally. But it’s good for us to do that once in a while, especially when the risk is to achieve a desired result. 1.
Our human nature should be to take risks, but some just sit and wish they would not have the fear to move on because of one or two failures in their lives. Please step out and don't let the past hold you back from living life to the fullest. 2..
In studying the psychology of taking risks, we find that human nature provides us with the desire to experiment and take chances. 3.. This risk-taking attitude has become a part of our modern culture. Roller Coasters and bungee jumping are two common risk-taking activities that even the average person seems to enjoy despite the logical understanding that danger is not fun. This psychological connection creates an interesting connection between what is safe and what human enjoys.
Without taking risks, nothing good can happen. Getting in a car each day is a risk. Getting out of bed is a risk.4.. We need to take risks so that we can accomplish things. Astronauts take risks when they get inside of a rocket; however, the things they achieve are literally astronomical. Investors take a risk when they buy parts of a company. However, without doing that, they couldn’t receive money on their investment.
5.. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or do anything else without taking a risk. That is all part of the game. It’s not one of the most important parts of life.
A.Move forward and move on
B.There is no such thing as a perfect safety.
C.In that way, we become stronger and braver.
D.Thus, we will achieve more success in daily life.
E.We need to take risks so that we can gain something.
F.You must spend more time thinking about the strategies of risk.
G.Risk-taking is a benefit that allowed ancient people to discover new places.

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
1.According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious B. it can’t harm people’s health
C. it can lower cancer risk D. it is not taken enough every day
2.Which of the following can not help people get more Vitamin D?
A. Have some sunshine B. Have more meat
C. Have more fortified cheese D. Have a vitamin supplement
3.Who can Garland probably be?
A. A health researcher B. A doctor
C. A scientist D. A public health official
4.Which of the following food can lower people‘s chance of getting cancer?
A. Milk B. Fortified orange juice
C. Fortified yogurt D. All of the above
5.People from which area should take more Vitamin D according to the passage?
A. Asian people B. African people
C. American people D. European people

There are many ways of defining success. It is accurate to say that each of us has our own ideas of success to the extent that each of us is responsible for setting our own goals and determining whether we have met these goals satisfactorily. Because each of us possesses unique differences in genetic ability and favorable environments in which to express these abilities, it is necessarily true that we must define success broadly.
For some people，simply being able to live their life with the least misery and sufferings is considered a success. Think of the peace of mind of the poor shepherd who tends his sheep, enjoys his simple life with his family in the beauty of nature, and who is respected because he does a good job of achieving the goals expected of him and accepted by his family and his society. On the other hand, it seems that even though some people appear to be rich in material possessions, many of them seem to be miserable and consider themselves unsuccessful when judged by their own standards of success. Because not all ventures can be successful, one should not set unrealistic goals for achieving success, but if one has self-confidence it would be unfortunate to set one's goals at too low a level of achievement.
A wise man once said to a young man who was experiencing frustration (挫折）with his own professional success, “You do not have to set your goal to reach the moon in order to have success in traveling. Sometimes one can be very successful merely by taking a walk in the park or riding the subway downtown,” The man added, "You have not really failed and spoiled your chances for success until you have been unsuccessful at something you really like，and to which you have given your best effort. ”
1.According to the first paragraph, what is implied as basic in achieving success?
A. Ability and goals. B. Goals and determination.
C. Ability and environment. D. Goals and environment.
2.Some rich people consider themselves unsuccessful because ______.
A. they haven't reached their own standards
B. their life is busy and miserable
C. they set their goals at too low a level
D. they are not rich in material possessions
3. From the last paragraph we can tell that ______.
A. success means achieving great goals
B. success comes from great goal setting
C. success has nothing to do with the distance of your travel
D. success means efforts and favorites pay off
4.The purpose of the passage is ______.
A. to talk about how to achieve success
B. to give us a clear definition of what success is
C. to state what our life goal is
D. to discuss the importance of goals

If you are taking vitamin supplements to reduce your risk of heart disease or cancer, a group of health experts want you to know that those vitamins may actually increase your risk of cancer.
The US Preventive Services Task Force came to this conclusion after reviewing dozens of studies.
Nearly half of adults in the US take at least one vitamin or mineral supplement on a regular basis. These pills are advertised as a way to promote general health. In some cases, producers promote them as cancer fighters and heart protectors.
Studies in animals and in laboratory dishes suggest that oxidative(氧化性的) stress contributes to diseases like cancer and heart disease. If so, there is a reason to believe that antioxidants—including beta－carotene, vitamins A, C, and E—could be useful as preventive medicines.
But when the Task Force examined the medical evidence on vitamins, it found “inadequate(不充分的) evidence” to support the claims that vitamin and mineral supplements benefit healthy adults.
“Cardiovascular(心血管的) disease and cancer have a significant health impact in America, and we all want to find ways to prevent these diseases，” Dr. Virginia Moyer, who heads the Task Force, said in a statement. But so far, she added, the medical evidence does not show that taking vitamins is helpful in this aspect.
However, the Task Force did find “adequate evidence” that people with a raised risk for lung cancer actually increase their risk further by taking beta－carotene, a precursor of vitamin A.
The Task Force recommendations of taking vitamins regularly apply to healthy adults aged 50 and older who don't have “ special nutritional needs”. The advice does not apply to children, women who are pregnant or may become pregnant, people with chronic illnesses, or people who have to take supplements because they can't get all their essential nutrients from their diet.
1.Studies in animals and in laboratory dishes find out________．
A. adequate evidence that taking vitamins are helpful for treating lung cancer
B. cardiovascular disease spreads very fast in America
C. oxidative stress can lead to heart disease and cancer
D. people must take vitamins on a regular basis
2.What can we conclude from Task Force's findings?
A. Scientists want to control cardiovascular disease.
B. In some aspects, taking vitamins is not useful.
C. Producers cannot produce medical－use vitamins.
D. Vitamins must be useful to prevent cancer and heart disease.
3.Who can take vitamins regularly according to the advice of the Task Force?
A. A 60－year－old healthy worker.
B. A 15－year－old boy with short－sightedness.
C. A 34－year－old pregnant lady.
D. A 40－year－old man who never eats vegetables or fruits.
4.What's the best title for the text?
A. An Inside Look at Vitamins
B. Task Force: Ending to Vitamins
C. Vitamins: To Live or to Kill
D. Taking Vitamins to Prevent Diseases May Fail
