Question

【题目】Maps of the world’s population show that the majority of people today live near water. 【1】We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water. More interesting, this human favor for water makes evolutionary sense. 【2】

Neuroscientist(神经系统科学家) Michael Crawford of the University of North London has proposed that our ancient ancestors attached to the sea, and that their devotion paid off by allowing the human species to develop large and complex brains. Crawford claims that when humans separated from apes and appeared in the forests of Africa, they stuck close to rivers and beaches and started catching fish and crabs.【3】

It's no coincidence, Crawford claims, that human brain growth began to increase rapidly once we left the woods and headed for the beach.

【4】Psychiatrist(精神病学家)and biochemist Joseph Hibbelin of National Institutes of Health has shown that across cultures there is direct link between amount of fish eaten each week and rates of depression. More interesting, Hibbelin and researcher Laura Reis have found that fish is commonly used as a symbol of happiness and good health in various religions and cultures.

【5】We vacation on the coast and see the waves come and go, feeling happiness has taken over our brain. When we move inland, or go home from vacation, we lose touch with our sea roots and feel unhappy.

A. Sure, we need drinking water to live, but we have also benefited from what’s swimming under waves.

B. We know that fish and the sea are good for us, and we seek them out.

C. We live along coastlines, around bays, up the course of rivers and streams and on islands.

D. Scientists help people overcome depression.

E. Scientists have also discovered that people who eat fish regularly are less likely to suffer from depression than those who eat less seafood.

F. It is good for our health to swim under the waves.

G. That sea food was packed with omega-3 fatty acids, essential fatty acids that promote brain cell growth.
