Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（結腸） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? 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. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium（硒）
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi（壽司）
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（節(jié)省）on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(無效對照劑). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
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（致癌物質） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. 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 metastasis(轉移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.

If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault.
Have you ever found that some people can't read or write but they have better memories? This is because they cannot read or write and they have to remember things; they cannot write them down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised.
So if you want to have a good memory, learn from the people: practise remembering.
小題1:If you do not use your arms or legs for some time, ______.
A．you can't use them any more
B．they will become stronger
C．they become weak but they slowly become strong again

Mom noticed that something was wrong when I started getting so thirsty. I’d have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I’d drunk the entire container! My mom called my doctor. I then had a few blood tests, and the results were certain — I had diabetes (糖尿病), which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.
My eating habits had to change in a big way. With diabetes, I can’t eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰島素) before the meal to help my body process the food. Also, I test my blood-sugar level often. I’m always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn’t keep me out of gym class or off the basketball court — I just keep some juice boxes around to boost my blood sugar if I need to.
It’s a lot of work — and not a lot of fun — to keep track of everything, but I’ve gotten used to my new habits. I was a little scared at first because I wasn’t sure how my life would change. Once I knew what I needed to do, though, it wasn’t a big deal. My life is different now from what it was before, but it has become completely regular to me.
小題1:The first paragraph is mainly about _____.
A．who found the author had diabetes

A．She stopped playing basketball in the gym.
B．She controlled her blood-sugar level strictly.
C．She stopped eating food with natural sugar.
D．She tested her blood-sugar level before every meal.

A．Increase.B．Control.C．Absorb.D．Test.
小題4:What’s the author’s attitude toward her having diabetes now?

Girls can easily get sad. If your friend is feeling blue and calls you, what will you do? Here are some tips on how you can make her smile again.
Listen to her. When people feel sad, they often have the feeling of needing to be heard. So, listen carefully to what she is saying and do nothing else. Your friend will surely thank you for being the shoulder she can cry on.
Once you are done with listening, you can offer some advice or remain silent and let her feel everything and let it all out by crying. As a friend, you might think you should give her some advice. But if you have no idea about what to say, just remain silent and be there for her.
In order to be able to help your friend in need, don’t be sad for yourself. How can you help your friend when you are also feeling down?
A hug can make a difference in the word. It makes you feel warm and special. A hug makes you feel safe. So give your friend a hug when she needs it the most.
Spend more time with your friend who wants to be happy. Do things together like washing dishes, cleaning, or going out for fun. The more time you spend together, the stronger your friendship will become.
Sometimes, it is much better that you avoid a crying friend in your life. But by doing so, you are also keeping your friend at a distance and will make her wonder if you are her true friend. If you are there when she needs you, your friendship will be much stronger.

There is one type of illness in the world that affects more people than anything else and is very deadly. If untreated this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change.
Everyone's circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude.
So how can we change the way we think, feel, and cultivate a cheerful attitude?
First we must look at ourselves, truly and honestly examining our motives for what we wish to achieve. If you are dissatisfied because you feel you haven't or can't do anything, then one step is needed - to set goals.
Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals.
It takes more than just setting goals to be happy. It takes positive thinking. How can we attain this?
There are a number of factors that can make us think negatively and one of those is diet.
In my opinion, a person who eats a lot of take out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it's much easier for your mental body or "thinking ability" to be happy.
Next, exercise. A half-hour a day is recommended for positive well being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day.
If you follow these steps, positive change is inevitable.
小題1:Which of the statements about depression is TRUE?
A．Depression is a kind of illness that can’t be cured like some cancer.
B．Depression can all be cured successfully by patients themselves.
C．Those who suffer from depression feel dissatisfied with themselves.
D．Those who suffer from depression live in similar circumstances.
小題2:According to the passage we can learn that ____________.
A．a practical goal can help people to achieve a sense of success
B．we shouldn’t be satisfied with small goals that are insignificant
C．we should avoid challenging goals that may lead to failure
D．people can enjoy happiness only if they set reasonable goals
小題3:In order to achieve positive thinking a person should do these things EXCEPT____________.
A．set challenging goalsB．eat healthier foods
C．exercise half an hour a dayD．always wear a smile
小題4:What’s the passage mainly about?
A．To prove the argument that depression can be changed.
B．To analyze the danger depression can bring to people.
C．To introduce to readers how to keep positive thinking.
D．To recommend some ways to deal with depression.

Sport is not only physically challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes(運動員). Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.
　　The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents' and coaches' criticisms to heart and find a flaw (缺陷) in themselves.
　　Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today's youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find fault with youngsters' performances. Positive reinforcement should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.
小題1:An effective way to prevent the burnout of young athletes is ______
A．to reduce their mental stress
B．to increase their sense of success
C．to make sports less competitive
D．to make sports more challenging
小題2:According to the passage sport is positive for young people in that ____ .
A．it can help them learn more about society
B．it enables them to find flaws in themselves
C．it can provide them with valuable experiences
D．it teaches them how to set realistic goals for themselves
小題3:Many coaches and parents are in the habit of criticizing young athletes ______ .
A．believing that criticism is beneficial for their early development
B．without realizing criticism may destroy their self confidence
C．in order to make them remember life's lessons
D．so as to put more pressure on them
小題4:According to the passage parents and coaches should _____________ .
A．pay more attention to letting children enjoy sports
B．help children to win every game
C．train children to cope with stress
D．enable children to understand the positive aspect of sports
小題5:The author's purpose in writing the passage is ____________ .
A．to teach young athletes how to avoid burnout
B．to persuade young children not to worry about criticism
C．to stress the importance of positive reinforcement to children
D．to discuss the skill of combining criticism with encouragement

It seems school children all over the world complain about their school food. Cherie Blair, the wife of Prime Minister Tony Blair, said that she would prepare a packed lunch for her son if school dinners do not improve. So what do students of your age eat for lunch at school?
Japan
High schools have canteens(餐廳), which serve everything from noodles to rice, but not burgers and chips. Other children bring food from home such as cold rice balls, meat or fish, pickles(泡菜) and vegetables.
Students take home a menu for the coming month containing notes on nutrition value. Twice a year parents are invited to have a taste of the food. The class with the fewest leftovers(剩飯) at the end of the month receives a prize.
Untied States
A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies. School lunches must also provide at least one-third of the daily dietary allowances(定量) of protein, vitamin A, vitamin C, iron, calcium, and calories.
Australia
Meat pies, sausage rolls and hotdogs are all traditional dishes in Australian school shops. But as the nation pays more attention to children’s health, healthier foods have started to find their way onto school menus.
Many schools have used a traffic light system. The sale of red-labelled foods, including pastries(點心), chocolate and soft drinks, is served only twice a week. Healthier green-labelled foods such as sushi(壽司), sandwiches, corn and watermelon, however, are available every day.
In some schools, students have a choice of up to 89 foods to choose from, including popcorn and rice.
South Africa
Most of South Africa’s schools do not serve meals at all. Classes end at 1:30pm and students get their own lunches. Many students bring food from home, usually sandwiches.
Fast food and fried food sell the best among students, which has led to a rise in obesity among children. But as more people began to realize the fact that being too fat may cause different diseases, some schools in towns have led the way towards better nutrition. Now students at these schools are provided with lunches of porridge(麥片粥) with vegetables, such as cabbages, onions, beans, carrots and tomatoes.
小題1:What does the underlined word “obesity ”in the last paragraph probably mean?

Science can’t explain the power of pets，but many studies have shown that the company of pets can help lower blood pressure(血壓) and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tell you how much joy a pet brings．For some．an animal provides more comfort than a husband／wife．A 2002 study by Karen Allen of the State University of New York measured stress(緊張)1evels and blood pressure in people－h(huán)alf of them pet owners－while they performed 5 minutes of mental arithmetic(算術)or held a hand in ice water．Subjects completed the tasks alone，with a husband／wife，a close friend or with a pet．People with pets did it best．Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates．With pets in the room，people also made fewer math mistakes than when doing in front of other companions．It seems people feel more relaxed(放松)around pets，says Allen，who thinks it may be because pets don’t judge．
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits．Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs；a separate group of 56 people without pets were put on a diet program．On average，people lost about 11 pounds，or 5％ of their body weight．Their dogs did even better，losing an average of 12 pounds，more than 15％of their body weight．Dog owners didn’t lose any more weight than those without dogs but，say researchers，got more exercise overall－mostly with their dogs--and found it worth doing．
小題1:What does the text mainly discuss?
A．What pets bring to their owners．
B．How pets help people calm down．
C．People’s opinions of keeping pets．
D．Pet’s value in medical research．

A fad diet is a diet that suddenly becomes popular, usually because it promises people that they will lose a lot of weight overnight. Although dieters may really show weight loss from a fad diet, they will almost certainly get back the weight if their usual eating habits (習慣) remain unchanged.

Worse yet, certain fad diets don't include nutrients(營養(yǎng))good for health. People have been known to become very ill as a result of following medically unhealthy diets.
