　　Vegetable gardening is the relaxing art and science of turning a love for growing plants into a worthwhile activity.

　　Vegetable gardeners agree that many home-grown vegetables picked at their best are better than those bought from markets. From spring through late fall, a well-planned and well-kept garden can provide a supply of fresh vegetables, thus increasing the nutrition (营养)of the family diet. Freezers make it possible to keep some of the vegetables to be enjoyed at a later date. Other vegetables can be stored for a few months in a cool area.

　　Having vegetables in the backyard makes home gardening attractive for many people. Besides, vegetable gardening provides exercise and fun for families.

　　Although the money spent for a garden may be little, one cannot escape the fact that gardening requires hard work and time. Many of the gardening tasks must be performed at times that are most inconvenient. Not doing jobs that should be done on a regular base may result in failure and a negative (消极的) feeling toward gardening.

　　One should not plant a garden that is too large for him to care for. A small , well-kept garden is more enjoyable and profitable (有益的) than a large one. Vegetables do well in full sunlight and need at least five or six hours of sun during the middle of the day. Too much shading results in poor plants and few vegetables. If possible, the garden should be near the house so the gardener can work at it at irregular moments.

　　Usually the home owner has little choice in the soil type he can choose. Fortunately many vegetables can be grown on poor soils if the soils are properly prepared.

1．Which of the following is true about home-grown vegetables?

[　　]

A．They can remain standing for a long time and needn't be picked immediately.

B．They have to be eaten as soon as they are picked.

C．They sell well in the market because of their top quality.

D．Vegetables picked at the right moment are more nutritious than those bought from the market.

2．Why is vegetable gardening attractive for many people?

[　　]

A．It requires little money.

B．It is enjoyable and profitable.

C．It provides vegetables for the family all the year round.

D．They can work in the vegetable garden at irregular moments.

3．It is suggested in the passage that an ideal (理想的) vegetable ________.

[　　]

4．From the passage we can conclude that ________.

[　　]

A．vegetable gardening is a good way to kill time for old people

B．vegetables can be grown in almost any kind of soil

C．vegetables need little care while growing

D．vegetable gardening is a necessary part of life for people

　　Considered as a continuous body of fluid (流体), the atmosphere (大气) is another kind of ocean. Yet, in view of the total amount of rain and snow on land areas in the course of a year, one of the most amazing water facts is the very small amount of water in the atmosphere at any given time. The volume (体积) of the lower seven miles of the atmosphere, where weather events take place, is roughly four times the volume of the world's oceans. But the atmosphere contains very little water. It is chiefly in the form of vapor (蒸气), some of which is carried over land by air currents. If all vapor suddenly fell from the air onto the earth's surface, it would form a layer only about one inch thick. A heavy rainstorm on a given area may use up only a small percentage of the water from the air mass that passes over. How, then, can some land areas receive more than 400 inches of rain per year? How can several inches of rain fall during a single storm in a few minutes or hours? The answer is that rain- producing air masses are always moving, and as the driving air mass moves on, new damp air takes its place.

　　The basic source of most water vapor is the ocean. Evaporation (蒸发), vapor transport, and rainfall make up the continuous movement of water from ocean to atmosphere to land and hack to the sea．Rivers return water to the sea．In the underground, flowing bodies of water send out some water directly into rivers and some directly to the sea．

(1)What might have been discussed in the preceding (在前的)paragraphs?

[　　]

(2)It can be inferred from the passage that ________.

[　　]

A．the atmosphere has a lot of water in it when it goes around

B．the water in the atmosphere is purer than that in the world's oceans

C．the amount of water in the atmosphere is greater than that in the oceans in the world

D．the small amount of water in the atmosphere plays an important part in the rainfall on the earth

(3)Which fact does this passage lead us to believe?

[　　]

A．The volume of the atmosphere is four times that of the world's oceans.

B．The water in the oceans is the main source of rain and snow on land areas.

C．The atmosphere is mainly made up of the vapor carried over land by air currents.

D．The earth cannot support the water in the atmosphere if it falls down onto the earth suddenly．
