【题目】 It is the season for long lines and frayed nerves. Here’s how to deal.

Lighten up

Do yourself a favor and ship your presents. Nearly every U.S. airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.

Weigh your options

Now knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.

Leave amateurs in the dust

Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced fliers, and it’s a hard walking. Plus, if you decide to cut it close, you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.

Take it public

The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories (财产) have increased dramatically. True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.

Say no to bumper cars

Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX, now feature this sensible choice.

【题目】 Scientists don’t know yet whether cell phones are bad for the brain.1

In the experiment, the 47 participants may have looked a little strange. Each of them had two Samsung cell phones tied to his or her head—one on each ear.2 The phone on the right ear played a message for 50 minutes, but the participants couldn’t hear it because the sound was off. After 50 minutes with two phone attached to their heads, the participants were given PET scans. The PET scan is a way to take a three-dimensional picture of how the inside of the bodyworks.

The PET scan showed that the left side of each participant’s brain hadn’t changed from the way it was before the experiment.3 These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that brain cells there were active even without the person hearing or talking anything. This activity, the scientists say, was probably touched off by radiation from the phone.

4 They release different amounts of radiation depending on whether a person is talking or listening, the type of phone, the number of people using phones nearby, and the distance to the nearest cell phone tower. All of these changes make it difficult to collect evidence about any health risks of cell phones, since exposure to radiation can vary.

So for those who don’t want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely.5

A.The phone on the left ear was off.

B.So an experiment was done to attempt to find it out.

C.People should avoid having a long conversation by using cell phones.

D.Cell phones do not always give out the same amount of energy.

E.You can have short conversations, use a speakerphone to keep the phone away from your head.

F.The right side of the brain, however, had used more glucose, which provided fuel to brain cells.

G.From the PET scan the differences between the two sides of the brain were observed.
