If so, you probably noted the Vshaped formation of the birds or the birds flying in a balllike 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 Vshaped 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 bees 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 bees 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 balllike formation. Researchers believe that the birds e together if a predator(天敵) is spotted. The predator may then bee 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 success takes care of itself.” When it es to teamwork, these feathered fliers are a soaring success!63. According to the passage, we can learn that birds ___________. A. move faster than cyclists B. prefer to fly in a V formationC. are smarter than other animalsD. play different roles in a formation 64. When food is sighted, ____________.A. the group follows the discoverer B. the lead bird decides what to doC. the discoverer leaves the group D. the whole group forms a stream65. To protect themselves from attack, birds will _____________ .A. break into groups B. e close together C. change directions D. fly up and down66. Which is the best title for the passage?A. A Bird’sEye View of Teamwork.B. Success Takes Care of Itself. C. The Strongest Will Survive.D. A Science Behind Flying.D A MythIt is true that world population is growing, but this is not the cause of our current and future global problems. Believing this will cause us to ignore the real problem and risk longterm damage to our planet.Let me start by explaining why overpopulation is a myth. For one thing, the UN Population Division regularly predicts population growth but provides a low variant (變量), medium variant, and high variant to factor in various possibilities. In the 2010 revision, their high variant suggests that the world population will be almost 16 billion in 2100, but the low variant predicts it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has e true in the past, suggesting the same will be true of their future population predictions. In addition to this, the size of families is actually decreasing. For another, if the Earth is overpopulated, there needs to be insufficient (短缺) food, water, and space for humans to live. However, Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world’s
