One of the most popular vacation destinations for young families is the home of relatives. {#blank#}1{#/blank#}  Here are some tips for making sure you are invited back again.

    Be considerate

    Every family has their own way of doing things. Keep these things in mind when you're visiting.

    If your host family are early to bed and early to rise, don't keep them up talking until one o'clock in the morning.

    If your host family gets angry about kids running wild, either plan to keep a close eye on your kids or plan to stay somewhere else. {#blank#}2{#/blank#} 

    Offer to help out

    Playing host to a family with children can be quite a challenge. Make sure you help lighten the load.

    {#blank#}3{#/blank#} Offer to help with cooking and cleanup. Make your beds and run to the store for milk. Better yet, don't ask. Just start working.

    Help pay for food

    This may not apply, if you're visiting parents and they insist on paying for everything and they can afford it. {#blank#}4{#/blank#}  Use your judgment when it comes to parents. However, if you're visiting cousins, it will be a great help to them if you buy your  share of the food.

    Show your appreciation

    No matter whom you are visiting, make sure you let them know you appreciate their hospitality(盛情招待). {#blank#}5{#/blank#}  Or leave some fresh flowers when you leave. If you don't have enough money, write them a letter, letting them know how much fun you had and how much you appreciate them.

A．Don't expect your hosts to supply your every need.

B．Offer to take them out to dinner on your last night in town.

C．Make sure you don't leave your things behind while visiting a family.

D．In that case you may hurt your parents if you insist on paying for food.

E．Try not to disturb someone who is in the middle of exams.

F．Staying with relatives is a great way to save money while getting away from home for a while.

G．Having a talk with your children about expected behavior while visiting is always a good idea.

    Both men and women are living longer these days in industrialized countries.{#blank#}1{#/blank#}In general, they can expect to live six or seven years more than men. One reason for this is biological. One important biological factor that helps women live longer is the difference in hormones between men and women. {#blank#}2{#/blank#} Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

    {#blank#}3{#/blank#}They help the body defend itself against some kinds of infections. This means that women generally get sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.{#blank#}4{#/blank#}Scientists are still not exactly sure how they influence aging, but they believe that they do. Some think that a woman's body cells have a tendency(向) to age more slowly than a man's. Others think that a man's body cells have a tendency to age more quickly.{#blank#}5{#/blank#}

A. However, women, on average, live longer.

B .The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. However, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control carious body functions.

    You already know an environmentalist's three R's: reduce, reuse, recycle. {#blank#}1{#/blank#} Here are three things you can do for the Earth Day.

    Be a real cut-up

    The next time you're about to throw out the plastic rings that hold a six-pack of soda together, reach for a pair of scissors.

    As a young turtle, Peanut got stuck in one of these rings. As she grew, the ring stayed put, forcing her shell to grow around it. By the time someone found her and cut her free, her shell was permanently deformed. Thanks to her hard shell, Peanut is alive and well. She now lives at a nature center in Missouri. But most animals that get caught in six-pack rings die.

    WHAT YOU CAN DO

    Easy! {#blank#}2{#/blank#}

    Hunt for vampires（吸血鬼）

    You know all those electronic inventions you've got at home? Even when you switch them off, they are really still on. {#blank#}3{#/blank#} Anything with a glowing LED off/on light, a remote control, or a clock display is always on.

    WHAT YOU CAN DO

    Just pull out the plugs or tap the OFF switch till you really need the electronics.

    Matt Damon really cares about clean water. So in February, he announced that he was going on strike against toilets. " Until everybody has access to clean water and sanitation（卫生设备）," he said. "I will not go to the bathroom!" He was kidding but to make a serious point. Around the world, he said, "780 million people lack access to clean water; 2.5 billion people lack access to a toilet."

    WHAT YOU CAN DO

    No need to go on a toilet strike. Just don't waste water. {#blank#}5{#/blank#}Take shorter showers.

A. Use water wisely.

B. How to recognize vampire electronics?

C. Cut the rings apart before you trash them.

D. Use toilets less.

E. But how else can you help?

F. Don't run the water while brushing your teeth.

G. Things that can help with good living conditions are important.

    What is happiness? When you can feel inner peace and satisfaction, you are happy. {#blank#}1{#/blank#} This usually happens when we do something we love or achieve something that we value. It is our opinions that make us feel happy or unhappy. All of us constantly go through various situations or conditions, but we do not have to let them influence our reactions and feelings. {#blank#}2{#/blank#}

    Try hard to make a change of the way you look at things. {#blank#}3{#/blank#} That means looking at the good and positive side of every situation. Pay attention to solutions, not problems. Listen to relaxing and uplifting music. Watch funny and interesting programs that make you laugh.

    Always look at what you have done and not at what you haven't done. Look at what you can do, not at what you cannot do. Each day do at least one act to make others happy. When you make someone happy, you'll become happy, and then people will try to make you happy. {#blank#}4{#/blank#} On the contrary, be happy for their happiness. Communicate with happy people and try to learn from them to be happy. Remember, do your best to stay detached (冷静的) when things do not occur as intended and desired. Detachment has much to do with inner peace. {#blank#}5{#/blank#}

A travel journal is one of the best ways to keep a long voyage in memory. Many details that don't seem important while you are writing your travel journal often turn out to be so memorable.

{#blank#}1{#/blank#}. When you are on a busy journey, it is easy to forget to write. You may promise yourself that you will write later, but that almost never happens. Take a few minutes every day and put down your memories.{#blank#}2{#/blank#}.

Use your “down time” for your travel journal. There is a surprising amount of sitting around while traveling. You can always put down a few lines in your travel journal when you are on trains, waiting for planes, drying your laundry, or waiting in line.

At the beginning of your journal, write down the day, where you are, who you are with, maybe even the weather and what you eat. {#blank#}3{#/blank#}. Years later when you read your journal, you will know exactly what you were doing on that day.

Focus on writing about how you feel. Listing facts and figures is fine but that isn't why you traveled. A long journey is a time for self-reflection. Memories of these feelings fade quickly with time.{#blank#}4{#/blank#}.

{#blank#}5{#/blank#}. Whenever you use a ticket for a train or a museum or a ride, tape the stubs to your journal. They are pieces of history from your journey. Years later you can look at the ticket stubs and see exactly what you were doing on a specific day and how much it cost.

A. Keep ticket stubs.

B. Book your ticket in advance.

C. You'd better write down as much as possible.

D. These are the first details people tend to forget.

E. It doesn't have to be long, just on a regular basis.

F. Get into the habit of writing your travel journal every day.

G. Writing about those experiences while the memories are fresh is important.
