Task 4
概念解释、实验描述的都OK
后面概念和例子结合的地方没说完,可以这样说:according to the experimenter effect, the experimenter has prior expectations for the smarter monkeys, so he smiles and work hard to train them, thus affect the result of the experiment.
你语速有点慢,可以的话尽量说快一些
Task 6
你这个引出例子的方式很好,很简练
第一个点没问题,最好把hulk逮的mice也说出来
第二个点,the eyes on each side allow ducks to watch out for all directions, so they can avoid predators like fox...这里说的不太好
其他OK。语速还是有点慢
