托福综合写作范文Sample answer:
In the lecture, the professor refutes against the view raised in the reading that starlings are harmful species, and he suggests they can bring benefits to human.
Firstly, the reading holds that they will cause some agricultural damage because they eat crops. However, the professor refutes that although starlings eat crops, they also eat insects that harm the crops. So farmers don’t have to use pesticides, which not only helps save money, but also helps protect the environment since pesticides will pollute the environment. What’s more, the reduction of pesticide is beneficial to the health of human being.
Secondly, the reading claims that the natural tendency of starling to flock together will pose danger to the airport. But the professor disagrees with this by suggesting that people could build a cage as trap, with some starlings and food in it. When other starlings see those starlings being feed in the cage, natural instinct will force them to form a flock and fly into the cage. So they will be captured and thus can be moved to other locations.
Finally, in the reading passage, they will compete with endangered species for they often occupy the nesting boxes constructed by human to protect endangered species. In contrast, the professor holds that the nesting boxes can be built with smaller entrance so that starlings cannot access easily because they are larger than endangered animals.
