一直留到了现在才跟delta的开始一起做。发上来求拍,请各位T友多提宝贵意见,bow。 In the set of materials given, the reading passage and the lecture give quite different opinions to the topic of altruism in animals and human beings. The reading passage assumes that an altruist serving for the interest of others shows great selflessness and may get nothing in return, whereas the lecturer supposes that altruism may, in fact, more benefit those who make sacrifice.
As an example given in both the passage and the lecture, meerkat is described, in the passage, to be willing to stand guard for the other members of the group at a price of losing food or even life. The passage also suggests that a sentinel meerkat is more likely to be caught by the predator because it can only escape alone after sending an alarm of danger. However, in the lecture, the professor said that recent researches showed the sentinel meerkats were always taking their position as guards after they have eaten food, thus leaving other meerkats to eat in even greater danger. Contrary to the assumption in the passage, the sentinel meerkats were found to be always the first to discover the predators and be able to have enough time to escape after sending out an alarm, which called the attention of the other meerkats and caused them to get together or fleet in different directions, thus catching the predator's attention away and leaving the sentinels in a safer situation.
Another example discussed was human organ donors. The passage suggests that they only benefit another people and get little reword in return, but the lecturer refutes that the donors are actually appreciated by the receiver and his family, or even other people and the donor may also feel self-contended.
The passage and the lecture contradict with each other in whether an altruist can get reward through the selfless deed or not. The conclusion of the passage says no while that of the lecture says yes.
