關于whether R. robustus is active hunter of dinasaurs. 一個叫R.的生物胃里面發(fā)現(xiàn)了恐龍的殘骸,于是科學家們爭論它是不是恐龍Hunter或者只是食腐動物。
Reading passage 認為不是,listening反對。給出三點supporting ideas:
1. reading說它的size is small, as big as domestic cat.但listening 說它的size是big enough to eat baby dinasaurs, 它的size even 比baby dinasaur 的兩倍還大。
2. reading說它的legs short, 不可能跑很快,追不上恐龍, position也不適于hunting,但listening 說可以,舉例論證:Tasmanian Devil,它的腿也很短,就是R. robustus的情況,但是它就是active Predator.所以(ancient) R.robustus could also do that.
3.reading說在R. robustus stomach里的dinasaur bones provide no evidence, 因為沒teeth mark。但listening說R. robustus的jaws 很強壯發(fā)育的很好,可以swallow in whole or in large pieces,表示R. robustus不用back teeth.
獨立寫作:
The personal and work-related challenges that young people face today are not very different from the challenges their parents and grandparents faced in the past.
