Question

C

Gordon Sato was born in Los Angeles in the 1920s. He learned to make corn grow in the dry and dusty soil. He later became a cell biologist. He earned many honours for his research.

In 1985， he went to Eritrea. There he noticed that camels were eating the leaves of mangrove trees(红树)growing along the coast. He planted more mangroves so they could be used to feed livestock. But at first all the new trees died. Then Gordon Sato observed that mangrove trees only grew naturally where there was fresh water some of the time. The fresh water provided minerals(矿物质)that salt water lacked. Gordon Sato found a way to provide these minerals by putting the minerals into small plastic bags at the base of each tree. Each plastic bag had a tiny hole that was very careful?ly sized.

The women in the village of Hargigo started to feed the leaves of the mangrove trees to their sheep and goats. But the animals were not produ?cing enough milk for their babies. Gordon Sato asked the villagers to grind (磨碎)the remains of fish they had eaten and spread this fish paste on the leaves. This provided protein for the sheep and goats so they could produce more milk.

Today there are more than one million mangrove trees around the vil?lage. Gordon Sato has also started a large garden in Mauritania to grow more mangrove trees. He is always looking for new projects and new ways to pay for them. "You don't have to be brilliant to do useful work. All you have to have is intelligence and determination, and you can make a contribu?tion to this world," Gordon Sato said.

Answer 1

C

[文章大意]Gordon Sato是一位生物学家，他帮助一个村庄种植了很多红树，使那里的牲畜有足够的树叶吃。

9. C 细节理解题。根据文章第二段的"There he noticed that... so they could be used to feed livestock."可知，Gordon Sato决定种植更多的红树来供村庄内的牲畜吃

10.B 细节理解题。根据文章第二段的"Then Gordon &to observed ...fresh water provided minerals(矿物质）that salt water lacked."可知，那些红树起初死了是因为它们缺少某些矿物质。 

11. B 细节理解题。根据文章第三段的"This provided protein for the sheep and goats so they could produce more milk."可知''，磨碎鱼'骨头是为了给牲畜提供蛋白质。

12. C 推理判断题。根据文章末段的"you have to have is intelligence and detef
ruination, and you can make a contribution to this world…"可知,只要我们拥有
智慧和决心，我们都可以为这个世界做出一些贡献。
