New findings in scientific areas can examine and challenge previous assumptions. A recent finding concerning the meerkat, a burrow-dwelling animal in the African grasslands, has cast doubt upon the conventional ideas of altruism, the type of behavior in which an animal sacrifices its own interests for the benefit of another.

Meerkats were previously thought to be a typical altruistic animal. When the other meerkats feed, there is usually one meerkat watching out for predators. The sentinel meerkat gains nothing, it seems, for it can neither eat nor escape quickly and successfully after raising an alarm.

However, in the new findings, it's shown that the sentinel meerkat has already eaten food before standing guard, thus contradicting the thought that it has an empty belly while on the lookout. In addition to this, the sentinel is the first to see a predator, so it is the first to escape. It is also placed nearest a burrow, making it relatively easier to flee. Moreover, its alarm calls may cause the group either to gather or to spread rapidly, which may attract the predator's attention, providing the sentinel a better chance to escape.

The same is with supposed human altruistic behavior. Organ donation to strangers may be considered an unselfish act, which provides little reward to the donator. However, by donating his organ, the donator may most probably receive praise and appreciation from others. Isn't this non-material reward, which increases one's self worth, satisfactory to anyone?

托福写作的误区：语法并非可有可无

现在很多考友是生活在用英语的环境之中的，比如说在美国或者英国上高中的。当然也有很多考友是在国内纯英语的国际学校求学，这些环境往往是全英文的环境。本来一个全英文的环境是十分有助于英语水平的提升的，但实际上，纯英语的环境对于英语的语法要求并不严格。换句话说，有可能一句话虽然有语病，但是由于对方能听懂，因此他也没有纠正你，那么你也默认这里是没有问题的。因此我们会看到很多英语环境之内的考生，往往在作文的部分折戟沉沙铁未销，就是因为这个关键性的语法的问题。因此，当我们在准备作文部分以及口语部分这些主观题的时候，要注意在考试之前一定要好好打磨一下自己的语法，否则后患无穷!
