  托福加试分为听力加试和阅读加试。今天环球托福老师先给大家讲讲托福阅读加试。
  托福阅读加试的位置一般不固定,并且一般不算分。但不意味着考生就可以随意应付。因为有时候你判断不出这篇阅读到底是不是加试题。因此环球托福老师建议大家遇到的每道题度认真做。下面环球托福老师为大家整理了一篇阅读加试,大家可以了解一下。
  Entomology(昆虫学)蜜蜂
  蜜蜂的沟通模式分为 honeybee和worker bee两种。文章讲了honeybee是如何寻找蜜源并告诉同伴蜜源的位置。开头先说蜜蜂和白蚁termite 等很多物种不同,他们是social。蜜蜂是一个是由社会分工合作的动物(有题目问到他们有哪些共同点),因此交流变得很重要(这里会出题)。科学家们便开始用他们的聪明才智研究小蜜蜂。一开始以为honeybee是靠scent交流,后来某个德国科学家研究发现 scout 用舞蹈来告诉工蜂蜜源的远近,远的用八字舞,近的用圆圈舞。他因此获奖。交流的内容靠跳八字舞或者圆圈舞来区别距离,而不是食物的类别(这里会有题)。发现蜜蜂找到窝以后跳舞是指示food type,后来发现 more than that。跳舞还指示出了direction and distance。跳舞分两种一种是 nectar 花蜜dance 另一种 pollen花粉 dance,(这里有题),nectar 是跳圆圈舞,pollen 是跳八字舞。但是一直有科学家怀疑。这个说法直到1989 年,一些科学家为了验证他的理论做了 machine bees 模仿 scout,就是不去有食物的地方(这里有考机器蜜蜂和其他小蜜蜂有什麼不同),发现 robot使用这些动作果然可以向工蜂有效传递资讯。采蜜只是跳舞来做一些指示。最后发现了小蜜蜂带回来的资讯和风无关(这里有问 except 的问题)
  Flowers provide food for bees. The bees collect tiny grains of pollen and a sweet liquid called nectar from the blossoms they visit. They make honey from the nectar, and use both honey and pollen as food.
  During their food-gathering flights, bees spread pollen from one flower to another, thus pollinating (fertilizing) the plants they visit. This enables the plants to reproduce.
  The honey bee colony
  A typical honey bee colony is made up of one queen, tens of thousands of workers, and a few hundred drones 雄峰.
  Honey bees live in hives. The hive is a storage space, such as a hollow tree or a box, which contains a honeycomb蜂窝. The honeycomb is a mass of six-sided compartments隔间 called cells.
  Worker bees build the honeycomb of wax produced by their bodies. The wax oozes渗出 through small pores (holes) in the body and forms tiny white flakes on the outside of the abdomen.
  They also collect a sticky substance bee glue, from certain kinds of trees.
  The body of the honey bee
  A bee has five eyes-three small ones that form a triangle on top of its head, and a large compound eye on each side of its head.
  Honey bees were the first insects known to be able to distinguish colors. Bees have three kinds of color-sensitive cells in their eyes. These visual cells are especially sensitive to blue, yellow, and ultraviolet rays, which humans can’t see.
  The sting of a worker bee is straight, with barbs (hooks) on it. When the bee thrusts the sting into flesh, the barbs hold tight, and the stinger 蛰针 pulls out of the bee's body.
  托福阅读加试可能有也可能没有,即使有,位置也不固定。考生们不要盲目去猜测,以免应影响成绩。
