Below is some advice on how to prevent cancer:

    Eat blueberries

    Aside from being a healthy and delicious snack, the blueberries contains pterostilbene, which has important colon(结肠) cancer-fighting. {#blank#}1{#/blank#}. Blueberries also offer a large dose of vitamins C. So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.

    Relax

    {#blank#}2{#/blank#}? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer.{#blank#}3{#/blank#}!

    Break a Sweat

    {#blank#}4{#/blank#}. In a study of 29,110 men published in The International Journal of Cancer, men who exercised just once a week had a percent lower risk of prostate cancer than men who didn't work out at all. The better the frequency and intensity of the exercise, the bigger the reduction in risk, according to the study.

    There's no question that secondhand smoke kills, A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物）in their body than nonsmokers working in smoke-free locations. What's worse, their levels of the carcinogen rose 6 percent for every working hour. Many states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.

    Everyone knows that fish is good for health. {#blank#}1{#/blank#}But it seems that many people don't cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn't difficult. {#blank#}2{#/blank#}This text is about how to buy and cook fish in an easy way.

    {#blank#}3{#/blank#}Fresh fish should smell sweet: you should feel that you're standing at the ocean's edge. Any fishy or strong smell means the fish isn't fresh. {#blank#}4{#/blank#}When you have bought a fish and arrive home, you'd better store the fish in the refrigerator if you don't cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn't as tasty as the fresh one.

    There are many common methods used to cook fish. {#blank#}5{#/blank#}First, clean it and season it with your choice of spices (调料). Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it's ready to serve.

A. Do not buy it.

B. The easiest is to steam it.

C. This is how you can do it.

D. It just requires a little knowledge.

E. The fish will go bad within hours.

F. When buying fish, you should first smell it.

G. The fats in fish are thought to help prevent heart disease.

    Volunteering abroad is a mind-opening experience that exposes one to other cultures, languages and ways of life.{#blank#}1{#/blank#}, the volunteer learns to appreciate the gifts of his home culture, as well as the benefits of the new. These volunteer opportunities often offer additional professional benefits, as well.

    The Satisfaction of Altruism (无私)

    Any volunteer job instills a sense of "giving back." However, overseas volunteering can be truly meaningful in this area. People in foreign cultures understand that you might be giving up numerous creature comforts to help them out.{#blank#}2{#/blank#}.

    New Language Skills

    Overseas volunteers may not only learn a new language during their stay, they may also come to appreciate their native tongue all the more. Total being involved in the culture will require at least a conversational grasp of the language. Often, English speakers are called upon to teach English as a second language, which requires relearning often-forgotten rules of grammar and usage.{#blank#}3{#/blank#}.

    Better Manners

    If the expression "ugly American" rings a bell, know that overseas volunteering is an excellent cure for that particular problem.{#blank#}4{#/blank#}. The lessons may lead to the volunteer thinking twice about how their behavior appears to others in daily life.

    {#blank#}5{#/blank#}.

    Going to a foreign country for a volunteer experience is a huge boost (帮助) on a resume. Employers love to see a person that can think outside the box and work past their comfort zone. The added benefits of teamwork, foreign language knowledge, and plain old hard work also add polish (品味) to the volunteer candidate. Since business now happens on a global scale, the volunteer is armed with useful, and potentially actionable, information.

A. Professional Benefits

B. An expanded appreciation of different traditions

C. By experiencing day-to-day existence in an area of need

D. Because of this, the act of giving is even more touching and deep

E. This repeat education can lead to better English skills in the long run

F. Volunteers may taste fruits, plants and meats they've never experienced before

G. Volunteers receive a thorough education about movement, gestures, and conversation

    It's the water that makes our daily lives possible. That's why protecting source water is one of the primary missions at the Washington Suburban Sanitary Commission. We provide safe, clean drinking water to 1.8 million residents in Prince George's and Montgomery counties.{#blank#}1{#/blank#}

    One way we protect the water is through the watershed. The watershed reduces the pollutants reaching the reservoirs. They hold the source water that provides 30 percent of our customers with drinking water. That's over 600,000 people. For many years, we have issued permits to allow limited recreational use of the watershed. {#blank#}2{#/blank#} It's a quiet, beautiful area away from urban stress and traffic. And we use it ourselves and other activities to promote water and environmental awareness.

    {#blank#}3{#/blank#} Last year, the WSSC issued new regulations with new restrictions impacting all users, including, closing the watershed a month earlier in the fall and opening it a month later in the spring. We also limited horseback riding to the access roads. Our goal was and is to protect the watershed.

    A very small but vocal group felt we should have consulted them first. Perhaps afterward we should have. But I do want to make one thing very clear. {#blank#}4{#/blank#} But we cannot allow the interests of a tiny group to override (不理会) the well­being of the WSSC customers who drink the water from those reservoirs. There must be a balance.

    {#blank#}5{#/blank#} So we hired a consultant to gather data, gather input from watershed users, and assess the condition of the watershed. We also asked them to look at our operations and management practices and provide the WSSC with findings and recommendations on how to make improvements.

    It's time to work together to protect the water and provide appropriate access to the rare jewel we call the watershed.

A. We certainly understand the attraction.

B. At no time did we consider closing the watershed entirely.

C. However, only a few people like saving water.

D. But most importantly it's about protecting the water.

E. The government has taken some strong measures.

F. We take that responsibility very seriously.

G. A review of our watershed policies and regulations was overdue.
