1) Prehistoric villagers tended to work harder,suffer from more diseases, and eat the poorer diet than monadic hunters did. 显然此处the 是错的, 但tended ..suffer..and eat 也觉得不妥,刚考完GMAT,这种并列结构一定错,难道在TOEFL中就不认为错了么?
2)The Milky way is a flat spiral galaxy who contains an estimated 100 billion stars, including the Sun who显然错,但an estimated 100 billion stars 有这种用法么?
