16、at is the direct cause of the disappearance of meateating dinosaurs?AA meteors crashing.BThe dust blocking the suns light.CThe planteating dinosaurs death.DIt is still unknown.解析：选D推理判断题。根据文章中作者的口气“perhaps”和“we are not 100% sure what really happened”可判断，恐龙灭绝的原因还没有准确的说法。.语法填空I dont very often have a
