A
About 1,101 manatees(海牛) died in Florida last year, many from hunger. So last December, government
wildlife experts (专家) came up with a plan to give food to the manatees. They decided to feed them green
vegetables like lettuce and cabbage. Ron Mezich, an expert, said, “We’ re making a difference.” So far, they have
served up more than 193,000 pounds of lettuce to hungry manatees.
Manatees are huge sea animals that only eat sea grass and other plants that live in the sea. That’s one reason
why they’ re sometimes called “sea cows”.
Since 1967, Florida’s manatees have been on the US government’s list of endangered animals. Most dangers
to manatees come from humans. One of the biggest problems facing the animals are boats. Thousands of manatees
were hit or killed by boats. At one point, there were only about 2,000 manatees left in Florida. With protection, the
number increased. In 2016, there were more than 6,000 manatees.
However, as sea grass began to disappear, the number of manatees keeps going down again. Warming seas
with polluted water have created huge growths of algae (藻) on the ocean’s surface. The algae blocks the sunlight
that allows the sea grass to grow. In Indian River Lagoon, where manatees often go in the winter, about 90% of the
sea grass beds there have died off. Florida will work to help restore (恢复) sea grass beds. But that will take time.
Scientists still worry that hundreds more manatees could starve this winter.
1．How has the number of manatees changed over years?
A． B．C． D．
2．What is the meaning of the underlined word “starve”?
A．to die from hunger B．to eat up sea grass
C．to be hit by boats D．to lose swimming ability
3．Which is the best title for this passage?

C．Sea Grass Beds Restored for Manatees D．Reasons for Manatees’ Death Still Unclear

The coldest and most difficult place in the world to live is Antarctica (南极洲). It is the land of snow and ice
near the South Pole (南极). Most people do not think there is much life in the icy waters around it. They are wrong.
Actually, there are more than one hundred different kinds of animals there. The most famous animal of Antarctica is
the penguin (企鹅). Halley Bay (哈雷湾) was the world’s second largest home for penguins.
However, penguins are now in great danger. Recently, scientists found that the number of penguins has
dropped quickly. One of the main reasons is that many storms hit Halley Bay. Thousands of baby penguins died from
the terrible weather.
Scientists feel worried about this. Halley Bay used to be a safe place for penguins but now it isn’t. Luckily,
another home of penguins has gotten much bigger. In order to keep safe, many penguins have moved there. Although
penguins may have greater chance to keep alive, they are still facing the danger of dying out. Unless we do
something, they won’t have anywhere to go one day.
1．What can we know from the passage?
A．Antarctica is the coldest place in the world.
B．There were no living things in Antarctica.
C．Penguins are now well protected by human.
2．Why are penguins now in great danger?
A．Because Halley Bay was was the world’s second largest home for penguins.
B．Because the number of penguins has dropped quickly.

Welcome to the Amazon rainforest. As the largest rainforest in the world, it plays an important role in
keeping the balanced ecosystem (生态系统) on the Earth. With an area of around 6 million square kilometers, the
Amazon rainforest is more than half the size of China. This area has a great many species (物种). Actually, one in ten
known species in the world can be found here.
Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon. There are different
levels in the forest. At the bottom is a system of roots under the ground. Above that is leaf litter on the dark forest
floor. The next level is made up of shorter plants with large leaves. Then there are the towering ancient hardwoods,
and finally the tops of the trees which are taller than any other level of trees in the forest. Each level of the forest
forms its own little world, home to different kinds of living things.
More than 1,300 species of birds and over 400 species of mammals (哺乳动物) hide among the forest’s plant
life. This jaguar is one example. While a large number of jaguars survive here, they are only one part of this forest’s
food chain (食物链). They feed on at least 87 species, including frogs. These frogs, in turn, feed on insects which eat
leaves and fruit.
The Amazon rainforest is a treasure house of species that can be used for food or medicine. What’s more, the
Amazon rainforest breathes life into the planet by producing over 20 percent of all the Earth’s oxygen (O ). So it is
2
often known as the “lungs of the planet”.
