Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.The first paragraph is mainly about .

I remember the first time that I was extremely happy. I was about 8 years old when for the first time, there was a computer in the classroom. I remember that my teacher allowed each student to take turns to play various educational games on the computer. One day, I found the source code(编码)for one of these games. Without knowing or being taught any programming language, I was able to figure out some of the BASIC code. I just gave myself an infinite number of lives in the game, so I could continue playing it forever. This was also my first introduction to algebra, and I didn't even know it at the time. This was a decisive moment in my life. I was quite excited because of what I was learning and what I was able to do. As a result, I was enthusiastic for the rest of my life about self learning and computers, and I was quite happy doing them too.
I've noticed that people who are truly content with life are enthusiastic about what they do. This enthusiasm, along with good health, is the key to being happy. It also leads to self-confidence and content in life too. It may also lead to success, wealth, and achievements.
Success, wealth, or achievements can also bring some people happiness, yet I know plenty of rich people who are unhappy. I know many people with successful businesses that are not happy with what they are doing. I know people who continuously buy themselves new toys, such as cars, computers, and televisions, yet never seem content for too long. Please remember, happiness is the journey of life, not the destination.What can we know from Paragraph 1?
| A.The author has a great talent for algebra. |

| D.being enthusiastic about what you do is more important than wealth |
Babies are born yogis. Once we were all able to pull our toes up by our ears and laugh about it. Then we aged, got injured, and began carrying stress in our shoulders and back. In short, we lost our balance.
Yoga (瑜伽) is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. I was seriously out of balance when I started practicing yoga in 1999. I had plantar fascitis (足底筋膜炎) in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis. I was desperate for exercise. Yoga became my salvation (拯救) and even enhanced my other fitness activities. I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.
Yoga becomes part of your physical life. Your body grows stronger, more toned, and more flexible as you move from one pose to the other. I spent a week in Mexico at a yoga retreat (静修), and it was the first vacation on which I lost weight. “Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K. I. S. S. Guide to Yoga. “Because yoga helps maintain a balanced metabolism (新陈代谢), it also helps to regulate weight. Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need a boost of energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative poses.
Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves stress and anxiety. I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams. You should always leave a yoga practice feeling energized, not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the pose by letting go of the tension.
Yoga becomes part of your spiritual life. Yoga is practiced by people from all religions; it is not restricted to any religious group. Yoga teaches “right” living in how we deal with ourselves and others. As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness. Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.According to the third paragraph, yoga can help people.
| A.grow taller |
| B.lose weight |

While working in Southeast Asia in the mid 1990’s, I became a branch manager in a factory. At the beginning, I used human relations principles, such as putting myself into the others place to help gain trust. After a few months, I was told that the factory team members liked and trusted me.
Then the owner, seeing how everyone thought well of me, believed that I could become an instrument of change to carry out his several unpopular programs. The factory members resisted and eventually saw me as a puppet controlled by the owner. The more I insisted that they ‘follow orders’ the more they found ways to weaken the new changes.
Finally, I was replaced by a manager who knew enough to please both masters. Even though the owner did not like the fact that his new changes were not immediately applied, the new manager gained his power by the support received from his team together with an intention to find a way. What I learned was that your team must always see you as supportive of their needs, even to the extent that the owner may not be pleased that you are unable to follow their wishes. At the end of the day, if your people do not follow you then you are no longer in charge and will be replaced.
At first I blamed my boss for putting me in such a position. Then in honest reflection, I began to realize that he had probably hoped that I would have found some middle ground. What I could have done was to first obtain their advice about why they did not wish to follow the new policy changes, and then I should have used my influence with both the owner and team members to find a better way.
Though, in fact it is a painful lesson for me, it has served me well along my career path!What can we learn from the passage?

Although I started learning English during my college years, when I entered the States, I only understood two English words “Yes” and “No”. We learned many grammar rules but we could not make the language connections to the real English world. Language frustration worries almost all first generation immigrants. For example, I got a letter from a Chinese-American who has lived in the States for a long time and has a good IT job saying “My 11-year-old girl writes quite well, but as her parents, we could not even read her article.”In addition, my Chinese-American professor friend has difficulty reading a novel. Improving our English skills has become a long journey for all of us. Honestly, if I have a chance, I really want to reach out to everyone in the world who has had a similar experience: learning a second language in adulthood. I wish I could encourage them to speak out about the culture shock, frustration they felt about the differences between West and East.
I have mainly focused on my English writing since 2008 after I found “Literacy Volunteers”, an organization that specially focuses on helping immigrants improve their English. I decided to challenge myself, writing a story like an American. I saw many wonderful Americans there. As soon as I met my teacher Alice, I asked her to be my private language tutor and have taken Tims English class. Every week Alice and I have worked on my English essays sentence by sentence.
To observe the culture differences between West and East, occasionally, I posted a few of my English essays online. I mentioned previously about American culture; when people read the same article or even face the same situation, American and Chinese act very differently. In my viewpoint, these differences make America the strongest country in the world. I know you have the right to express your own opinions, but accusing others without proof is not acceptable.The underlined word “frustration” in the first paragraph means.
| A.failure and setbacks | B.words and problems |
| C.understanding and progress | D.slang and idioms |
In the passage, “Literacy Volunteers” is.
| A.only intended to help the Chinese-Americans |
| B.an organization which is set up to make a profit |
| C.of great use to people like the author |
| D.a school showing how to enjoy literature |
From the last paragraph we can learn that.
| A.Americans and Chinese are of the same idea about something |
| B.culture shock only exists between Chinese and Americans |
| C.accusing others freely can be acceptable in America |
| D.culture differences have great influence on the people |
The purpose of the passage is.
| A.to show how hard a Chinese-American lives in America |
| B.to share her experience of improving her English |
| C.to imply grammar rules are not important |
| D.to warn Chinese-Americans of English |
