托福写作模拟试题：橡子橡树的进化

　　托福综合写作范文Sample answer:

　　The reading and listening discuss about domestication of acorns and oaks. The reading points out that acorns and oaks can be domesticated. Whereas, the professor totally refutes the three points presented in the passage.

　　Firstly, the professor rebuts the reading’s first point that acorns, which have a long growing period, are easy to farm. He points out that it takes a long time for the acorns to ripe and fruit. Besides, early human beings immigrate frequently, so they have insufficient patience to wait until the oaks finally fruit.

　　According to the reading material, acorns are conventional food sources, which are unlikely to be spoiled. The professor mentions that while acorns will not be spoiled easily, the preparation is cumbersome, for chemical can be removed only by boiling.

　　At last, reading material point out that just as almonds whose unpleasant taste can be eliminated by cultivation and election for generations, so do acorns. However, the professor explains that it’s not proper to make a comparison between acorns and almonds. Almonds only possess one gene to decide their taste, while acorns have several genes accounting for their taste. Thus, dealing with acorns’ taste is a really complicated procedure, which is impossible for the early people.
