If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to explain the formation patterns of different types of birds. One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position. But saving energy is important for more than one reason. Sometimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals. When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change direction. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food. Scientists have also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustrating even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack. The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, "If everyone is moving forward together, then... Question: Which is the best title for the passage? Options: A: A Bird's-Eye View of Teamwork.

Article: A euphemism (from the Greek words eu--well and pheme--speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions.Most people,for example,would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed.They would soften the pain by saying:We had Ruby put down or We had Ruby put to sleep.Many people prefer to call someone plain than ugly,or cuddly rather than fat. Euphemisms are an important part of every language,but it seems that English has an evergrowing number of them.The nonnative speaker not only has to make sense of the euphemisms he hears,he also has to learn which euphemisms are appropriate in any particular situation.He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom,or comfort station) is,but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog.He might have learned,for example,that in the family way is a euphemism for pregnant.If,however,he says to his boss,"Congratulations!I hear your wife is in the family way," he would be using an expression that is too familiar for the circumstances. Schools are full of euphemisms.At Frankfurt International School,for example,the special lessons given to students who are having difficulties in their school subjects are called Study Center (in the middle school) and Academic Workshop (in the high school).Teachers rightly do not want to upset students or parents by being too frank or straightforward,and usually choose a softer word or expression to convey the same message. Question: According to the passage,people use euphemisms in order to _ . Options: A: make themselves understood B: avoid embarrassment C: to sound straightforward D: attract attention

These drivers just drove slowly, taking their own sweet time, as if they had nothing to do and no place in particular to go. Thus, the expression, " _ ", was born. Consequently, a Sunday driver wasn't necessarily someone who was driving on a Sunday. A person could be a Sunday driver any day of the week. _ . The expression probably came about because there was a time when people would often decide to go for a relaxing drive on Sunday afternoons. A Sunday drive was a common occurrence years ago and especially on a nice warm sunny day. There were no stores open on Sunday because of the "blue laws", so you needed to be sure and fill up the gas tank and make any other needed purchases before Sunday arrived. Some of the states had strict blue laws that even prohibited some activities on Sunday. However, there is still a lot to be said for the slow, gentle life that once existed. It was a time when very few people worked on Sunday except for those professions vital to our well-being such as those in the medical profession. It was a day "set apart" that was used to rest, visit with neighbors and friends, or maybe go to grandma's house for supper. Today there are many who return to work and children who go back to school overly tired on Monday due to a lack of rest. Perhaps there would be less stress related illnesses if we really kept Sunday as a day of rest. Question: What kind of activity was strictly prohibited on Sunday by the laws? Options: A: Visiting with neighbors and friends. B: Going to the hospital to see a doctor. C: Having a family get-together. D: Selling goods or services.
