The holiday season isn't just about shopping and gifts. {#blank#}1{#/blank#} However, holiday travel can be more expensive than the gifts. Fortunately, the following tips will help keep your travel spending under control.

● Plan ahead. The earlier you book your travel, from airfare to hotels, the easier it is to find good deals. {#blank#}2{#/blank#} Your best prices on airfare come when you book three weeks before the plane leaves for domestic flights. For international flights, consider booking 30 days in advance. Many experts point out that you should book travel between  one month and three months out for high-traffic holidays.

● Book your air travel on cheaper days. Traveling by air on Tuesdays and Wednesdays often costs less than traveling on Fridays and Sundays. During the holidays, it is not just about a specific day of the week. You also need to consider the days surrounding the holiday but days immediately before and after a holiday can be expensive. One of the best ways to save is to plan your air travel on the Day of the holiday. {#blank#}3{#/blank#}

● Consider traveling overnight. Red-eye flights and overnight flights often cost less than those at more convenient times. {#blank#}4{#/blank#}Traveling overnight can help you avoid a night in the hotel, as well as save your money on travel to your destination.

●{#blank#}5{#/blank#} You can't bring liquids with you on the airline, but you can bring sandwiches and other snacks. When you are on the road, you can buy food at local groceries to make your own meals. If you are staying in a hotel long-term, consider cooking your own food, especially if you have access to a microwave.

    The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

    But just as in face to face communication, there are some rules of behavior that should be followed when on line. {#blank#}1{#/blank#} Imagine how you'd feel if you were in the other person's shoes.

    For anything you're about to send: ask yourself, “Would I say this to the person's face?” if the answer is no, rewrite and reread. {#blank#}2{#/blank#} 

    If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. {#blank#}3{#/blank#} If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    {#blank#}4{#/blank#} Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. {#blank#}5{#/blank#} At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.

    It is not polite to ask others personal questions such as their age, sex and income. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

A. It's natural that there are some people who speak rudely or make mistakes online.

B. Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face.

C. Everyone was new to the network once.

D. The basic rule is simple: treat others in the same way you would want to be treated.

E. When you send short messages to a person online, you must say something beautiful to hear.

F. You should either ignore the person, or use your chat software to block their messages.

G. If you do decide to tell someone about a mistake, point it out politely.

    How Many Cups of Coffee per Day Are Too Many?

    From cappuccinos to cold brew, coffee is a must-have to start the day for many people. {#blank#}1{#/blank#} However, a new study suggests too much coffee can be harmful.

    This is what a recent study shows. {#blank#}2{#/blank#} A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won't hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee.

    Knowing the limits of what's good for us and what's not is necessary. {#blank#}3{#/blank#} About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure. {#blank#}4{#/blank#}

    Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful.

    {#blank#}5{#/blank#} Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day.

A. Drink no more than six cups per day.

B. Over the limits and our health will pay for it.

C. Coffee is the most popular drink in the world.

D. But of course, don't forget to listen to our body.

E. The relation between them is quite complicated.

F. As we know, it is a key heart disease risk factor.

G. It sets you off on an energetic morning and prepares you for a busy day.
