We’re always being sent contributions（稿件） for our popular laughter, The Best Medicine Section. Some of the jokes are obvious winners. Some of the jokes are ancient,  which are unfit for public consumption or just don’t make the grade（符合要求）. And then there are the rest: the jokes that get our editor scratching his chin and wondering, “Is this one good enough to print? ” Now you can help him choose. We’ve picked five jokes from the “Maybe” pile. Vote for the one you think is the best. The top-rated joke as of July 20, 2012 will be published in the magazine—and net its author $150.

Your chair is your enemy. That is the conclusion of several recent studies. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don’t.

       So what’s wrong with sitting? The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.

       You may think you have no choice about how much you sit. But this isn’t true. Suppose you sleep for eight hours each day, and exercise for one. That still leaves 15 hours of activities. Even if you exercise, most of the energy you burn will be burnt during these 15 hours, so weight gain is often the cumulative(累积的) effect of a series of small decisions: Do you take the stairs or the elevator? Do you walk to the corner store, or drive?

       But it looks as though there’s a more sinister aspect to sitting. Some evidence suggests that when you spend long periods sitting, your body actually does things that are bad for you.

       Lipoprotein lipase(蛋白脂酶) is a molecule that plays a central role in how the body processes fats. Low levels of lipoprotein lipase are associated with a variety of health problems. Studies in rats show that leg muscles only produce this molecule when they are actively being moved. The result is that when you sit, an important part of your metabolism(新陈代谢) slows down. You may also have a higher risk of suffering from diabetes(糖尿病).

       Some people have advanced radical solutions to the sitting syndrome(综合症): replace your sit-down desk with a stand-up desk, or watch television in a rocking chair. But whatever you choose, know this. The data is clear; look out for your chair.

What would be the best title of this passage?

Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil (零), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的).

Fly on non-stop routes

Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.

Choose larger aircraft. www.7caiedu.cn

   Although small aircrafts have very good safety records, those with more than 30 passenger seats are designed to comply (遵守) with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.

Pay attention to the pre-flight safety briefing

The information may seem repetitious (重复的), but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.

Store things safely

Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence (气流).

Keep our seat belt fastened while you are seated

Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.

Let the flight attendant pour your hot drinks

Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.

A. What to do in the event of a crash.

A. Larger planes have more safety checks and are safer in an accident.

B. Take-offs are safer on non-stop flights than landings.

C. Every aircraft is different, so the safety procedures may be different.

5.The best title of the passage should be _______.

A. The Safest Way to Travel        B. Air Safety Tips
