1 . Social media is so common in our society that almost everyone is connected to some forms of it, whether it is Twitter, Facebook or even Pinterest. We are in a fast­paced, technologically­evolving society and we are addicted to social media. In fact, we crave (渴望) social media.

    1     We share what we’re doing, how amazingly we did on a test and so on. Simply speaking, we love people knowing what we're doing. It has become a place that can define us.

Our social networks can tell a story about us, and if you’re like me, you want to make sure that the story your Twitter or Facebook tells about you is a good story.     2     How does one ensure a positive online reputation? Here are some tips.

1. Keep it clean:     3     Party photos with alcohol are an absolute no­no. Would you want to have your boss see these photos? Make sure to post contents that you feel positively reflects you, your creativity and your skills.

2. Don’t trust privacy settings: You have a private Twitter account so you can post anything you want?     4     Privacy settings make it harder to see your full account, but it’s not impossible. You shouldn't rely on privacy settings as a way to protect inappropriate (不适当的) content.

3. Ensure you’re polished: Keep it classy (优等的)!     5     Think about what you want people to think of you and go with it.

Like it or not, your social networks reflect you — make sure you look like the shining star that you truly are.

4 . It is well known that smoking is harmful to health. It is unfortunate that despite some individuals who choose not to smoke, they remain to be victims of various diseases caused by cigarette smoking.

Cigarette smoke contains thousands of dangerous chemicals that are unhealthy for both smokers and non-smokers. Secondhand smoke refers to the smoke from the burning end of a cigarette and the smoke breathed by smokers. More than 126 million Americans are regularly exposed to secondhand smoke at home, at work, and in enclosed public spaces.

The Deadly Effects

Secondhand smoke can cause heart disease and lung cancer in non-smoking adults. Breathing secondhand smoke for even a short time increases risk for those diseases.

Children and infants are especially attacked by the poisons in secondhand smoke. Almost 3 million children in the United States under the age of six breathe secondhand smoke at home at least four days per week.

Secondhand smoke is a known cause of the sudden infant death syndrome, breathing problems, ear infections, and asthma attacks in infants and children.

Secondhand smoke in the home environment can slow the lung growth of exposed children. Older children whose parents smoke get bronchitis and pneumonia more often than the children of non-smokers. Wheezing (气喘) and coughing are also more common in children who breathe secondhand smoke.

Protecting Yourself and Others

The only way to fully protect yourself and loved ones from the dangerous chemicals in secondhand smoke is through 100 percent smoke-free environments. Opening a window; sitting in a separate area; or using ventilation (通风), air conditioning, or a fan cannot get rid of secondhand smoke exposure. If you are a smoker, the single best way to protect your family is to quit smoking.

Nowadays in real life, many people have all kinds of bad habits, but getting rid of them takes a bit more effort. Whether they’re “traditional (like biting your nails, snacking on junk food, gossiping, or twirling your hair) or more hi-tech (like texting), bad habits all have one thing in common: They’re hard to break. You can do it, though.

So if you’re ready, gather your willpower, follow these steps, and wave goodbye to that bad habit forever!

Step 1     1    

Make a note every time you engage in your habit. Write down the time and where you are, as well as how you’re feeling. Are you bored, angry, or sad? The more you understand the reason behind your habit, the more control you’ll have over it.

Step 2 Pay attention to when your bad habit pops up.

Do you see any patterns in your journal? Do you always bite your nails before a test? Are you more likely to eat junk food, like chips or candy, when you’re doing your homework? If you notice a pattern of your habit,     2     For example, if you bite your nails when you’re stressed, try to find other ways to calm yourself, like taking slow, deep breaths.

Step 3 Replace your bad habit with a good.

Instead of biting your nails or twirling your hair, keep your fingers busy drawing or knitting. If gossip is your problem, challenge yourself to say nice things about people. Each time you substitute your new activity for your old one,     3    

Step 4 Stay focused.

Write down a promise to yourself: “I will stop biting my nails” or “I will stop texting so much”. Make a list of the days of the week, and place a gold star next to each day that you don’t engage in your habit. If you can’t get through a whole day at first,     4     Before you know it, you’ll have a whole page of gold stars!

Step 5 Keep at it.

Maybe you’ve heard the expression “Old habits die hard”? Well, it’s true! It usually takes three weeks to a month to break a bad habit. So if you mess up one day, don’t give up!     5     Eventually you’ll have more successes than failures.

Remember, if you put your mind to it, you can do anything—even break that bad, bad habit!

From this year’s trip through Southeast Asia, last year’s Central America adventure and traveling within Canada, travel has been a(n)     1     (wonder) part of my life. My study abroad in Australia had such a huge impact     2     my life that I created my own travel blog Little Miss Ottawa as a way     3     (challenge) myself to experience Ottawa as a traveler would.

Whenever a friend or family member comes back from a trip, they always can’t wait to tell you about the highlights (最好的部分)! Research from San Francisco State University has shown that people feel     4     (comfortable) when they spend money on experiences than on other things and they feel the money is better spent.

Experiences are something I truly value. Your     5     (happy) increases with experiences, but the impact of people you meet along the way also matters. Some of my best    6     (trip) were when I went alone and I     7     (lucky) met people who would become friends for life. Now I have people I can visit all over the world. In fact,     8     is so easy to build friendships with other travelers because everyone is ready to meet new people. I jumped into my study abroad in Australia     9     (know) no one. I left with friendships     10     will last a lifetime. There’s something about going through experiences together that has bonded (建立关系) us for life.
