“Soon, you’re going to have to move out!” cried my neighbor upon seeing the largest tomato plant known to mankind, or at least known in my neighborhood.

One tiny 9-inch plant, bought for $1.25 in the spring, has already taken over much of my rose bed, covering much of other plants, and is well on its way to the front door.

 Roses require a good deal of care, and if it weren’t for the pleasure they give, it wouldn’t be worth the work. As it is, I have a garden full of sweet-smelling roses for most of the year. Bushes must be pruned(剪枝) in early spring, leaving ugly woody branches until the new growth appears a few weeks later. It was the space available in the garden that led me into planting just one little tomato plant. A big mistake.

Soil conditions made just perfect for roses turn out to be even more perfect for tomatoes. The daily watering coupled with full sun and regular fertilizing (施肥) have turned the little plant into a tall bush. The cage I placed around it as the plant grew has long disappeared under the thick leaves.

Now the task I face in harvesting the fruit is twofold; First, I have to find the red ones among the leaves, which means I almost have to stand on my head, and once found I have to reach down and under, pick the tomatoes and withdraw(缩回) my full fist without dropping the prize so dearly won. I found two full-blown white roses completely hidden as I picked tomatoes in June. But they were weak and the leaves already yellow for lack of light.

 Here I am faced with a painful small decision: To tear up a wonderful and productive tomato plant that offers up between ten and twenty ripe sweet tomatoes each day or say goodbye to several expensive and treasured roses. Like Scarlett in Gone With the Wind, I’ll think about that tomorrow.

阅读下列短文, 从所给的四个选项中, 选出最佳答案。

　　     How much rain has fallen on the earth in the past? Man has not always kept weather records. Because scientists need a way to learn about past rainfall, they study tree rings.

　　     A tree's trunk grows bigger each year. Beneath its bark (树皮), a tree adds a layer of new wood each year it lives. If you look at a tree stump (桩), you can see the layers. They are called annual rings (年轮).

　　     On some trees all of the rings are the same width. But the ponderosa pines that grow in the American southwest have rings of different width. The soil in the southwest is dry. The pines depend on rainfall for water. In a year of good rainfall, they form wide rings. In a dry year, they form narrow ones.

　　     Scientists do not have to cut down a pine to know its rings. With a special tool, they can remove a narrow piece of wood from the trunk without harming the tree. Then they look at the width of each ring to see how much rain fell in the year it formed.

　　     Some pines are hundreds of years old and have hundreds of rings. These rings form an annual record of past rainfall in the southwest.

[　　]

A. why tree trunks grow bigger 　　

B. how trees grow

[　　]

D. the ponderosa pine only grows in the American southwest

3. A new layer of wood grows in a tree ____________.

[　　]

A. each week　　

B. whenever it rains　　　　

C. every year　　

D. every season　　

4. Why does a ponderosa pine in the American southwest have rings

　　 of different width? ____________

[　　]

A. Because rainfall differs from year to year.

B. The bigger a pine grows, the wider rings it forms.

C. Scientists control its growth.

D. It grows in the dry soil.　　

5. Which of the following is true?

[　　]

A. The trunk of a tree never changes in size. 　　

B. Young trees have fewer annual rings. 　　

C. The soil in the southwest is fit for the growth of trees. 　　

D. It is with a special tool that scientists cut down a tree &

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

　　A. they had no idea about scientific forestry

3.To avoid repeating the mistakes of our forefathers, the author suggests that ______

　　A. we plant more trees

　　B. natural sciences be taught to everybody

　　C. environmental education be directed toward everyone

　　D. we return to nature

4.How can you understand the underlined sentence in the last paragraph?

A. Our living space on the earth is getting smaller and smaller.

B. Our living space should be measured in cubic volume.[来源:Z。xx。k.Com]
