If you're like most kids, you've probably hea...

If you're like most kids, you've probably heard at least one parent say, "Don't forget to take your vitamin(维他命)!" or "Eat your salad — it's packed with vitamins!" But what exactly are vitamins?

Vitamins and minerals are substances that are found in foods we eat. Your body needs them to work properly, so you grow and develop just like you should. When it comes to vitamins, each one has a special role to play. For example:Vitamin D in milk and fish helps your bones. Vitamin A in orange fruits and vegetables,liver and milk helps you see at night. Vitamin C in oranges and some green vegetables helps your body heal if you get a cut. Vitamin E in nuts, seeds, whole grains and green, leafy vegetables protects your lungs from becoming damaged by polluted air. B vitamins in green leafy vegetables help your body make energy from food.

When you eat foods that contain fat-soluble(脂溶性的) vitamins, the vitamins are stored in the fat tissues in your body and in your liver. They wait around in your body fat until your body needs them.

Fat-soluble vitamins are happy to stay stored in your body for a while — some stay for a few days, some for up to 6 months! Then, when it's time for them to be used, special carriers in your body take them to where they're needed. Vitamins A, D, E, and K are all fat-soluble vitamins.

Water-soluble vitamins are different. When you eat foods that have water-soluble vitamins, the vitamins don't get stored as much in your body. Instead, they travel through your bloodstream. Whatever your body doesn't use comes out of your body. So these kinds of vitamins need to be replaced often because they don't stick around! This crowd of vitamins includes vitamin C and the big group of B vitamins — B1 , B2 , B6 , B12 and so on.

Every living being has the right to warm shelter and good food, but most importantly, they have the right to be wanted and loved. They have the right to be a special, much loved member of their own family.

There are many organizations that deal with abused animals or animals that have no home like ASPCA, PETA, the Humane Society and many more.

There are many things you can do right now to help animals around your neighborhood.

What’s black and white and read all over? Not newspapers, at least not anymore. In fact, if you’re like most young people, you probably don’t read the newspaper at all.

In one recent survey, just 19 percent of 18 to 34-year-old said they read a newspaper every day, while 37 percent watch local TV news and 44 percent visit Internet news sites daily. As people turn more and more to new technologies, they turn the pages of newspapers less and less.

“There’s a revolution (革命) in the way young people get news,” says media consultant Merrill Brown.

Just a generation (一代人) or two ago, the newspaper was the main way that many people got their news. Now, nearly every home has at least one TV set. There’s high-speed, wireless Internet both at home and in many public places.

You no longer have to wait for a bundle of newsprint to arrive on your doorstep every morning. Thanks to new technology, if you want to know what’s going on in the world, you can get breaking news immediately in more ways than one.

So newspapers face a very big challenge. Raised on MTV and video games, today’s kids and young adults want flashy displays, special effects, quick information, and the chance to interact (互动) in real time, even when they’re reading about serious problems.

If newspapers can’t find creative ways to be more than just ink on paper, some experts suggest, they might disappear completely.

Traditional newspaper articles are supposed to be read from beginning to end, lack (缺乏) of interaction. With Web pages, on the other hand, there’s more freedom. You can look through the things you’re interested in, then follow links to other sources. You can join discussion groups, read other people’s opinions on a topic, or start a blog to express your own views.

1.This passage is mainly about ______.

A. the disappearing newspaper　　　　 B. different news sources

C. the future of the Internet　　　 D. the new technologies

2.From the survey, we can see that ______.

A. TV has become the major source of news

B. newspapers are no longer the major source of news

C. more than half of the 18-to-34-year-old visit news sites daily

D. new technologies have replaced the traditional one

3.According to the passage, which of the following is NOT mentioned about the disadvantage of newspapers?

A. High price.　　 　 B. Lack of changes.

C. Slow speed.　　　　 D. Lack of interaction.

4.The author of the passage would probably think the future of newspapers is ______.

A. attractive　　 B. bright

C. hopeless　　 D. uncertain

If you are like most international students, you are probably comfortable reading and writing in English. 1. Below are some tips to help you to improve your conversational skills.

Make friends with American students. Many international students end up making friends with a lot of—or only—other international students. 2. Hanging out with natives not only naturally pushes you to improve your spoken English, but also helps you pick up cultural and social information.

Learn from American friends. Tell your American friends that you are trying to improve your listening and speaking skills, and would like them to help you. If you pronounce a word incorrectly, or misuse an idiom, you ask them to guide you. 3.

Increase your knowledge. 4. If you are familiar with the topics that are likely to be discussed in conversation, you have a much better chance of understanding people when they talk, and of being able to express yourself well.

5. If you have to explain something to someone, you have a strong motivation to pronounce everything as well as you can, and find other ways to explain yourself. Finally, this becomes a good habit. Many people have asked me how I learned to speak English fluently, and I owe most of it to my years of being a math teacher in college for years.

A. It is bad for them to do that.

B. You will make progress this way.

C. Become a teacher at your school, if possible.

D. It's a win－win opportunity for international students.

E. Keep up with news and watch popular shows and movies.

F. Explaining everything in a different way matters.

G. However, you may have trouble in listening and speaking in the language.

How do you get a man to do his share of the housework? If you are like most women, you’ve faced this question the hard way.

A man will enjoy a clean, orderly house, but he usually won’t make the effort to clean or organize it. This doesn’t mean that a woman has to do all the housework; she may have to manage many of the household duties, and request her partner’s joining. A woman can often say that men and women should take equal responsibility for housework.

Very few men are raised to be fully responsible for housework, and many men look on housework as women’s work. On the other hand, most men will readily work around the yard, make repairs and complete projects on weekends or evenings, and it’s important that you give your man appreciation(欣赏) for those things, too. Most men will take on a little housework around the house if asked politely. They are even more likely to do housework if they can choose what they want to do , and do it without being monitored(监视).

Here is the key: men want to feel that they are doing housework either because they want to do a task, or they simply want to please their women. Men are less likely to take on household tasks they consider uninteresting and unimportant. In other words, men are likely to do a housework task just for the good of the house.

1.The passage is mainly about how to ________.

A．get men to do some housework            B．get men to serve their families
