With the rise of basic economy and budget airline models that charge extra for seat selection, it's become a lot harder for groups, especially families with kids, to secure seats next to each other.1..
2.. The earlier you book your family's travel, the more likely that you will be able to reserve seats that are next to each other.
Contact your airline and ask it to accommodate your family, if you can't initially be seated together. Discuss with the airline your concerns about a child being seated alone.3., they may be able to assure you that each child is seated next to an adult family member.
Check reservations and seat assignments directly with the airline, if you book through a third party online agency. If you did not book your travel directly with an airline, obtain or confirm your seat assignments directly with the airline as soon as possible before the day of travel.4. .
Confirm reservations and seat assignments again before you leave for the airport. You may wish to confirm your seat assignments before you would normally go to the airport as your seat assignments could have changed after booking due to an aircraft adjustment with a different seating arrangement.5.. They will do what they can to help families who need to sit together.
A.The earlier, the better
B.Book tickets as early as possible
C.Even if the airline is unable to seat the whole family together
D.Here are some tips to help you sit together without paying extra
E.Even though the airline is unwilling to take your concerns into consideration
F.If your seat assignments have changed, you can contact the airline to ask for help
G.This can be done either on the website or over the phone by contacting reservations
Anyone who commutes（通勤）by car knows that traffic jams are an unavoidable part of life. But humans are not alone in facing potential traffic jam. Ants also commute一between their nest and sources of food. The survival of their colonies（群体） depends on doing this efficiently.
"The more they are, the more food they're going to bring back. But at the same time, they might end up with traffic jam because there are too many of them.” Sebastien Motsch, a mathematician in Arizona State University said. When humans commute, there's a point at which cars become dense enough to slow down the flow of traffic, causing congestion. Motsch and his colleagues wanted to know if ants on the move could also get blocked. So they control traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food. Then they waited and watched.
The flow of ants did increase initially as ants started to fill the bridge and then stabilize at high densities. But it never slowed down, even when the bridge was nearly filled with ants. The researchers then took a closer look at how the behavior of individual ants impacted traffic as a whole. That meant cautiously tracking thousands of separate ants as they made their way across the bridge.
Motsch and his team found that when ants sense overcrowding, they adjust their speeds and avoid entering high-density areas, which prevents congestion. These behaviors may be made by pheromones （外激素），chemicals that tell other ants where a trail is. The ants also manage to avoid colliding with each other at high densities, which could really slow them down.
Can ants help us solve our own traffic problems? Not likely, says Motsch. That's because when it comes to getting from point A to point B as fast as possible, human drivers put their own goals first. Individual ants have to be more cooperative in order to feed the colony. But the research could be useful in bettering traffic flow for self-driving cars, which can be designed to be less like selfish humans一and more like ants.

A.They built bridges of different widths.
B.They made the ants on the move.
C.They watched the ants closely.

3.What is the result of the research?
A.The ants avoid entering high-density areas.
B.The ants never stop and no traffic jam happens.
C.The ants sense overcrowding and adjust their speed.
D.The ants give off chemicals to tell others where they can go.
4.What's the researchers' attitude to solving our own traffic jam?
A.Optimistic. B.Doubtful.
C.Indifferent. D.Supportive.
Every driver is familiar with the horrible blind spot problem. However, it is more than just an annoyance. According to the National Highway Traffic Safety Administration, over 840,000 car accidents occur due to the blind spot. Those zones which cannot be directly observed by the driver often causes incidents that result in serious property damage and in some cases even death.
While drivers can take precautions such as adjusting the driver's seat and side mirrors properly, installing backup cameras and so on, they won't remove the invisible spots completely. Therefore, the driver will always have to carry the responsibility of being constantly aware of blind spots because failing to do that can lead to accidents.
Luckily, now there's a solution to that and it comes from a 14-year-old girl, who doesn't even have a driver's license yet. However, not being able to drive didn't prevent Alaina Gassier from understanding the important issue of traffic accidents resulting from blind spots. In fact, she knows the problem so well that she actually solved it for us. And the way she did it is nothing but genius.
Her project is called "Improving Automobile Safety by Removing Blind Spots'* and work in a relatively simple way as she explained: "I did that by having a camera behind the A — pillar of a car and the camera sent the video to a projector that projected (投射)the image onto the pillar essentially making it invisible and making the driver see behind it."
To complete this invention, she used easily attainable materials such as a webcam, projector, and 3D-printed materials that project the view from outside your vehicle onto the blind spots of your car.
Gassier was awarded for her life-saving invention. It earned her the top place in a nationwide competition for middle schoolers with the $25,000 Samueli Foundation Prize in honor of overall STEM (Science, Technology, Engineering, Mathematics) excellence.
