Article: Dear Bewildered, Table manners are about being kind to and considerate of others.Having proper table manners is one way people judge others,and we don't want people to think that we are rude,do we ? Whether in a restaurant or in a home, here are some basic table manners for kids: 1Eat with a fork unless the food is meant to be eaten with fingers.Only babies eat with fingers. 2Sit up and do not hunch over your plate;wrists or forearms can rest on the table,or hands on lap. 3Chew with your mouth closed,No one wants to see food being chewed up.This includes no talking with your mouth full. 4Don't make any rude comments about any food being served.It will hurt someone's feelings.Always say thank you when you're served something. 5Eat slowly.It takes someone a long time to prepare the food,so enjoy it slowly.Wait about 5 seconds after swallowing to get another forkful . 6 Don't reach over someone's plate for something.Politely ask the dish to be passed to you. 7When eating at someone's home or being a guest of someone at a restaurant,always thank the host and tell him or her how much you enjoy it.At least say that you like the dinner ,for example, the dessert is great.

**Answer**
Guests should express thanks to the host after the meal.

Read the following article and select the best answer. Article: Once when I was six years old I saw an amazing picture in a book called True Stories from Nature about the primeval forest. It was a picture of a boa constrictor in the act of swallowing an animal. In the book it said:"Boa constrictors swallow their prey whole without chewing it. After that they are not able to move and they sleep through the six months that they need for digestion ." I thought deeply then over the adventures of the jungle. And after some work with a colored pencil I succeeded in making my first drawing. My Drawing Number One. I showed my work to the grown-ups and asked them whether the drawing frightened them. But they answered:"Frighten? Why should anyone be frightened by a hat?" My drawing was not a picture of a hat. It was a picture of a boa constrictor digesting an elephant. But since the grown-ups were not able to understand it, I made another drawing. I drew the inside of the boa constrictor so that the grown-ups could see it clearly. They always need to have things explained. That's my Drawing Number Two. The grown-ups' response this time was to advise me to lay aside my drawings of ba constrictors whether from the inside or the outside and devote myself instead to geography, history, arithmetic and grammar. That is why at the age of six I gave up what might have been a great painter. I had been _ by the failure of my Drawing Number One and my Drawing Number Two. Grown-ups never understand anything by themselves and it is tiresome for children to be always and forever explaining things to them. So then I chose another profession and learned to pilot airplanes. I have flown a little over all parts of the world; and it is true that geography has been very useful to me. At a glance I can distinguish China from Arizona. If one gets lost in the night, such knowledge is valuable. In the course of this life I have had lots of chances to meet with a great many people. And that hasn't much improved my opinion of them. Whenever I met one of them who seemed to me at all clear-sighted, I tried... Question: The writer drew his first picture in order to _ . - show the grown-ups what the book was about - frighten the grown-ups trying to enter the forest - remind himself of the adventures of the jungle - illustrate a boa constrictor's act of digesting an animal
**Answer**
illustrate a boa constrictor's act of digesting an animal

Read the following article and select the best answer. Article: Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer -- migrating birds fly in a "V" to save energy, according to a study published in the journal Nature. When a bird flaps its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost from the rising air and therefore use less energy to stay in the air. Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward. "They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC. In fact, the "V" formation has long thought to help birds fly more efficiently . A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof. "For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies -- helping them understand how they can _ that with their plane formations to save fuel, said Portugal." Question: What is the significance of the new study according to this article? - It might inspire aircraft companies to think of ways to improve efficiency. - It has proved that the "V" formation can improve in efficiency in many fields, - It has led scientists to discover that birds' heart rates go down when they fly in a "V". - It shows that the best formation of jet fighters in battle should be a "V" formation.
**Answer**
It might inspire aircraft companies to think of ways to improve efficiency.
