    You might dream of fluency in this or that language, and maybe you've already achieved fluency in a foreign language.{#blank#}1{#/blank#}.

    Fluency, like all abstract terms, has no universal meaning. Each individual must determine what the term means.{#blank#}2{#/blank#}.

    Perfect fluency means knowing every word you encounter, speaking quickly, clearly and easily and having no accent.{#blank#}3{#/blank#}. You aren't familiar with every word of your native language, and sometimes you have to search for the right word, even in your mother tongue.

    Quick fluency is the type of fluency you see in advertisements, because “Master a Language in Two Months!” sounds way catchier than “Fluency in Twenty Years!”{#blank#}4{#/blank#}. It is possible to achieve quick fluency, but the fluency achieved after such a short time frame will be a very thin, superficial fluency.

    {#blank#}5{#/blank#}. Native-like fluency means that you generally know all the same words that a native knows and can speak at the same pace with the same amount of ease as a native speaker. You will likely have an accent, but as long as your conversation partner can understand you, it doesn't matter.

    Literary fluency is like graduating from native-like to educated-native-like fluency. It focuses on the more intellectual（知识性的） side of a language: indulging in literature, attending university, composing song lyrics, etc.

    There are a ton of other things that fluency could potentially（可能地） be, but that's up to you to figure out.

A. It sounds too good to be true.

B. However, Nobody is “perfectly fluent” in any language.

C. Quick fluency is good if you have some sort of deadline.

D. But have you ever considered what fluency really means?

E. But does fluency have the same meaning to other person as it does to you?

F. Unlike perfect fluency, native-like fluency is a reasonable and attainable goal.

G. To assist you in determining what fluency is, I'll describe a few different types of fluency.

    Tiny Tomatoes

    Tomatoes come in a variety of sizes, shapes and colors. And the little tomatoes are some of the most fun to grow and are perhaps the most rewarding. 
    Little tomatoes are classified into plum, cherry, grape or currant (醋栗) tomatoes.   {#blank#}1{#/blank#} Plum tomatoes are the largest of the groups listed, and currant tomatoes are the smallest. There are also differences in color, flavor and skin thickness, but these differences are more relative to specific varieties.{#blank#}2{#/blank#}

    Plum, cherry and other small tomato types are fun to grow because they always produce abundant crops of flavorful fruit. They are fun to snack on while working in the garden or while daydreaming about working in the garden.{#blank#}3{#/blank#}They are typically sweeter than large tomatoes, and little tomatoes contain less juice and fewer seeds than large tomatoes.

    To grow little tomatoes, select a site that receives at least six to eight hours of full sun per day. Use a large container set in a sunny spot if a sunny planting site is otherwise unavailable.”

    {#blank#}4{#/blank#}You could also plant seeds, but already-started plants will provide fruit much more quickly. Water infrequently to help plants grow deep roots before the heat of summer arrives.

    Harvest fruits when they are ripe. They will generally slip from the plant at this point.{#blank#}5{#/blank#} Store harvested fruit indoors and unrefrigerated as cool temperatures change the flavor.

A. The best time to grow tomato plants is March.

B. Differences in size matter most commonly here.

C. They are also influenced by growing conditions.

D. Then select plants from the garden center or farmers.

E. All of them are delicious and almost of the same size.

Kids and food: advice for parents

    It is important for parents to know how to help their kids eat healthy. Here are a few easy ways:

    Parents control the supply lines.

    {#blank#}1{#/blank#}Though kids may keep asking for less nutritious foods, parents should decide which foods are regularly provided in the house. Kids won't go hungry. They'll eat what's available in the fridge at home.

    Say goodbye to “clean-plate club”.

    {#blank#}2{#/blank#}Lots of parents grew up under the clean-plate rule, but that way doesn't help kids listen to their own bodies when they are full. When kids feel full, they're likely to overeat.

    {#blank#}3{#/blank#}

    Food preferences are developed early in life, so try to offer different kinds of food. Likes and dislikes begin forming even when kids are babies. Parents may need to serve a new food on several different occasions(时机) for a child to accept it.

    Food is not love.

    Find better ways to say “I love you.” When foods are used to reward kids and show love, they may start to turn to food when feeling worried or unhappy. {#blank#}4{#/blank#}

    Kids do as you do.

    {#blank#}5{#/blank#}When trying to teach good eating habits, try to set the best example. Choose nutritious food, eat at the table, and don't forget breakfast.

A. Start them young.

B. Rewrite the kids' menu.

C. Be a role model and eat healthy yourself.

D. Offer praise and attention instead of food treats.

E. Let kids stop eating when they feel they've had enough.

F. You decide which foods to buy and when to serve them.

G. Let kids choose what to eat and how much of it they want.

    A good laugh is like a mild workout (锻炼). It exercises the muscles, gets the blood flowing, decreases blood pressure and improves sleep patterns and the immune system. {#blank#}1{#/blank#}

    Don't take life too seriously. We all have obstacles in life and we all make mistakes. {#blank#}2{#/blank#} In fact, if you can laugh light-heartedly at your own fault, you'll find that you give yourself that extra happiness and confidence increase that can get you over any obstacle.

    Find the humor in a bad situation. Sure, there are some situations where you are really sad. {#blank#}3{#/blank#} The next time you feel the stress levels rising, take a minute to think about the funny side of the situation and laugh over the things you cannot control. This will lower your blood pressure, blood sugar levels and heart rate.

    Remind yourself of funny moments from the past. Perhaps a friend told you a great joke the other day or your children or pets did something amusing. {#blank#}4{#/blank#} Sometimes just reliving (重温，再次体验) a funny moment can cause the endorphins(内啡肽), natural painkillers, to kick in.

    {#blank#}5{#/blank#} As the saying goes, laughter is contagious(会传染的）. So make a point of (重视) seeking out positive people who aren't afraid to laugh at themselves and are good at finding humor in life's situations. Young children are especially skilled at finding laughter and joy in everyday moments.

A. Take control over your emotions.

B. There is no reason to blame yourself for it.

C. However, most situations in life have funny sides.

D. Surround yourself with fun people who like to laugh a lot.

E. The following are some ways to enjoy more laughter and joy in your life.

    Actions speak louder than words. A smile says, "I like you. You make me happy."

    That's why dogs make such a hit. They are so glad to see us that they almost jump out of their skins. {#blank#}1{#/blank#}

    A baby's smile has the same effect. Have you ever been in a doctor's waiting room and looked around at all the sad faces waiting impatiently to be seen? There were six or seven patients waiting when a young woman came in with a nine-month-old baby. She sat down next to a gentleman who was more than a little impatient about the long wait for service. The baby just looked up at him with that great big smile that is so characteristic of babies. {#blank#}2{#/blank#} Soon he struck up a conversation with the woman about her baby and his grand-children and then the entire reception room joined in, and the boredom and tension were changed into a pleasant and enjoyable experience.

    {#blank#}3{#/blank#} Telephone companies throughout the U.S have a program called "phone power which is offered to employees who use the telephone for selling their Services or products. In this program they suggest that you smile when talking on the phone. Your "smile" comes through in your voice.

    You don't feel like smiling? {#blank#}4{#/blank#}If you are lone, force yourself to whistle or hum a tune or sing. Act as if you were already happy, and that will tend to make you happy.

    Your smile is a messenger of your goodwill. {#blank#}5{#/blank#} To someone who has seen a dozen people frown or turn their faces away, your smile is like the sun breaking through the clouds. Especially when that someone is under pressure from his bosses, his customers, his teachers or parents or children, a smile can help him realize that all is not hopeless-that there is joy in the world.
