With an improved economy，many travelers have been buying first or business class seats，leaving fewer for upgrades（升级）.Here are some strategies for getting a free upgrade.

1. Fly a lot.

This is the most common way to earn a free upgrade. Most airlines reserve some spaces for travelers who fly at least 5，000 miles per year. Five years ago，this meant half or more of domestic（国内的）first class travelers sat up front for free. But now，airlines are selling more high-price seats，so on popular routes it is not unusual for more than 20 travelers to compete for one or two upgrades. But on routes with fewer business class travelers，free upgrades remain more plentiful.

2. Use miles.

If you're not a frequent traveler but still have some miles to fly，you may be able to use them for an upgrade. Be careful，though，as many airlines now ask not just for miles but also a cash co-pay. One example: on flights to Europe，American Airlines charges 5，000 miles，plus $110，for a one-way upgrade from discounted economy class to business class. For most domestic upgrades，American Airlines wants 15，000 miles plus $ 75.

3. Get lucky.

Sometimes airlines overbook coach（经济舱），and a few travelers get no seats. Agents try to ensure the airline's most loyal travelers get the nod（被选中）. Agents usually have some flexibility to make sure the plane is full and takes off on time. So it's the easiest way for them to do it-they might upgrade someone else out of order.

4. Save a life.

Flight attendants don't usually upgrade passengers, even when empty seats remain. Doctors and nurses who answer an emergency call are sometimes an exception. If they comfort a passenger, flight attendants might allow them to sit in business or first class for the rest of the flight.

1. Curiosity

Your children need to be deeply curious. 【小题2】 Ask kids, “What ingredients (配料) can we add to make these pancakes even better next time?” and then try them out. Did those ingredients make the pancakes better? What could we try next time?

If someone were to do that to you, how would you feel?”

4. Self-expression

【小题5】 There are many ways to express thoughts and ideas — music, acting, drawing, building, photography. You may find that your child is attracted by one more than another.

   Have you ever had the following experience? You have been given the task of organizing a conference, which includes a must-do list about a mile long. There are the conference site, the guest list, the materials, the technology and even the food and drink to think about and plan. If you are beginning to feel the stress, slow down and take a breath. 【小题1】

Write down your goals. You will need to clearly define what you hope to accomplish with this conference because this will shape the rest of your decisions.【小题2】

Develop your budget.【小题3】 Then break that budget into different parts such as the conference site, materials and speakers’ fees. Stick to your budget, and make sure your assistants are keeping their monetary limits as well.

【小题4】 When searching for locations, keep in mind the number of participants, the convenience of the location, parking and closeness to public transportation, airports and hotels. Your goal in finding a place to hold the conference should be making it as easy as possible for participants to attend.

Seek help from the staff of the conference site. If you have chosen a site that is known for holding conferences, you can seek help from the staff there as organizing meetings is what they do every day.【小题5】 They should be able to answer any questions or concerns and provide advice when needed.

Of course, full preparations also include a walk-through. Go to the site and meet with the staff the day before to be certain that everything is in place and to take care of any small details.

   Several recent cases of violence（暴力）against students at U.S. colleges have made global headlines，arousing questions about the safety of America’s campuses. Yet government data show that the number of violent assaults（袭击）at colleges actually has decreased in recent years. And most schools have worked to increase safety through technology and student behavior.

It’s also important for students to take responsibility for their own safety. Being familiar with local neighborhoods and campus services is key. Personal-safety expert David Nance says the most important thing students can do is be attentive-which means not being distracted by smartphones or other devices.

The website for the group PEACE OUTSIDE CAMPUS，formed in response to the murder of a student from the University of Delaware in her off-campus apartment in 2005，lists additional measures students can take：

1. Don’t walk alone after dark or while drunk. Contact a friend to take you where you need to go.

2. When driving，keep your doors locked，and park in well-lit areas.

3. Don’t wear earphones or play music so loudly that you are unaware of your surroundings.

4. Trust your instinct（本能）and don’t worry about overreacting. You’re better safe than sorry.

5. Avoid entering elevators with strangers. When this is unavoidable，stand by the control panel and，if faced with a threatening way，push the emergency alarm and all the floor buttons. Don’t press the stop button.

6. Don’t hold the door open for a stranger attempting to enter the house，even if it seems rude. Ask them to identify themselves.

7. Post the police’s and fire departments’ numbers by every phone，and put them into your cellphone.

8. Label your emergency contacts as ICE（In Case of Emergency）in your cellphone so officials will know who to contact for important personal or medical information.
