The African elephant, the largest land animal remaining on earth, is of great importance to African eco-system. Unlike other animals, the African elephant is to a great degree the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna（大草原）surroundings in which it lives, therefore setting the terms of existence for millions of other animals and live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed（有蹄的）plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole eco-system.
66. What’s the passage mainly about?
A. Disappearance of African elephants.
B. Forests and savannas as habitats for African elephants.
C. The effect of African elephants’ search for food.
D. The eating habit of African elephants.

A. fixing the time. B. worsening the situation.
C. Improving the quality. D. Deciding the conditions.
68. What do we know about the open spaces in the passage?
A. They result from the destruction of rain forests.
B. They provide food mainly for African elephants.
C. They are home to many endangered animals.
D. They are attractive to plant-eating animals of different kinds.
69. According to the passage, which of the following statements is TRUE?
A. The African elephant has become extinct.
B. African elephants have 300 pounds of plants every day, including small trees and under-bushes.
C. The African elephant is in a way the builder of the environment like other land animals.
D. If the African elephant disappears, the whole eco-system won’t be affected.

“I’m seventy years old,” says the gray-haired lady proudly to the entertainer at her Community Club dinner.
“Did you hear that, everyone?” says the entertainer. “This lovely lady is just seventy years young! And she doesn’t look a day over fifty.” He has been careful not to use the word “old”. In a society where youth is so admired, old age is often seen as something sad, something to fight against. Americans prefer not to say “old” people. They use the expression “senior citizens”. They do not talk about “old people’s” homes, but “retirement” homes.
In fact, the entertainer is not so wrong. Seventy is not very old these days. People in the US are living longer and longer. In1980, 12 percent of Americans were over sixty-five years old. By 2030, 21 percent will be over sixty-five. One reason for this is that families are getting smaller. The average couple now has only 1.8 children. At the same time, improved medical care means that people are living longer.
This change in the age of Americans is going to have serious results. For one thing, medical costs are rising. The government is unable to pay the elderly people’s medical bills that have gone up very much. Some old people have to leave hospital “sicker and quicker” than they should, before they are really better.
More fortunate senior citizens, though, who still have good health, want new laws to be passed to allow them to stay at work. In the past, the retirement age was sixty-five, but that is changing now. Older people are stronger and more energetic than ever before. Many of them refuse to stop working just because they have reached a certain age.
There is a change, too, in the way in which elderly people see themselves. Many are no longer happy to accept the gray hair, bald heads, and boring clothes of their own parents. They like to wear younger-looking clothes and bright makeup（化妆品）.American women spend millions of dollars a year on operations to lift their faces and make those ugly wrinkles disappear. Men are prepared to spend even more on operations to plant new hair on their bald spots. It’s worth any money to look younger.
60. In America people try to avoid using the word “old” because ____.
A. the old age is seen as something that isn’t admired
B. it is now believed to bring bad luck to elderly people
C. the standard of getting old has changed
D. the change in the age has caused a healthy problem
61. According to the passage, which of the following does NOT describe the American society correctly?
A. People live longer because of improved medical care.
B. The government finds it difficult to afford the medical bills of the elderly.
C. People use polite expressions when talking about old age.
D. The old patients’ time in hospital is strictly limited.
62. Which of the following is not the result of the changing in the age of Americans?
A. Medical costs are rising.
B. The family becomes smaller.
C. The retirement age needs changing.
D. Elderly people spend a lot on keeping young.
63. This passage is most probably taken from .
A. a travel booklet B. a magazine
C. an advertisement D. a medical report

Each spring brings a new wildflower blooming in the fields along the highway I travel daily to work.
There is one particular blue flower that has always caught my eye. I've noticed that it blooms only in the morning hours. The afternoon sun is too warm for it. Every day each year for about two weeks, I see those beautiful flowers.
This spring, I started a wildflower garden in my yard. I can look out of the kitchen window while doing the dishes and see the flowers. I've often thought that those lovely blue flowers from the fields would look great in that bed alongside other wildflowers.
Every day I drove past the flowers, thinking, "I'll stop on my way home and dig them." "Gee, I don't want to get my good clothes dirty…" Whatever the reason, I never stopped to dig them. My husband even gave me a tool one year for that expressed purpose.
One day on my way home from work, I was saddened to see that the highway department had cleared up the fields and the pretty blue flowers were gone. I thought to myself, "Way to go, you waited too long. You should have done it when you first saw them blooming this spring. "
A week ago we were shocked and saddened to learn that my oldest sister-in-law has a cancer. She is 20 years older than my husband and unfortunately, because of age and distance, we haven't been as close as we all would have liked.
I couldn't help but see the connection between the pretty blue flowers and the relationship between my husband's sister and us. I do believe that God has given us some time left to plant some wonderful memories that will bloom every year for us.
And yes, if I see the blue flowers again, I'm sure I'll stop and transplant them to my wildflower garden.
【小题1】How long might the blue flower bloom in spring?

Trees are useful to man in three very important ways: they provide him with wood and other products；they give him shade；and they help to prevent drought and floods.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.
Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.
Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal(木炭) or selling wood to the townsman（城市居民）. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.
This does not only mean that the villager’s sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.
1.The purpose that the writer wrote this article is to _________.
A. tell people the use of wood
B. tell people the function of tree roots
C. warn that man mustn’t destroy forests any more
D. explain how trees help man live a better life.
2. In the writer’s opinion, _________, or the forests will slowly disappear.
A. measures must be taken
B. people shouldn’t draw benefit from the tree
C. government must realize the serious results
D. unless no trees are cut down.
3.According to the article we know it is ________ to prevent the forests from slowly disappearing.
A. necessary but impossible B. necessary but difficult
C. impossible and unimportant D. difficult and impossible
4.In the last two paragraphs the writer wanted to make it clear that _________.
A. where there are no trees, the soil becomes poor but soft
B. where there are many trees, there are more floods
C. where there are no trees, the land might become desert slowly
D. floods will make the land become desert
