Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?

To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why dry deserts everywhere are almost not covered by trees or grass.

Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.

Another thing plants must have before they can grow is food.

What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

 

49. According to the passage, plants need        things to grow well.

A. two                            B. three                        C. four                         D. five

50. From the passage, we can know it is     ______for plants to grow in dry places.

A. easy                  B. difficult                    C. impossible                D. important

51. The reason why most plants can't grow on the sandy beach is that       .

A. there isn't enough sunlight                             B. there is too much water

C. it is too crowded there                                  D. it has little food for plants

52. The passage can most probably be found in a       book.

A. science                    B. history                            C. travel                       D. math

Save the Animals
Animals are natural resources(資源) that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks(鷹), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

Some scientists suggest that these contacts with nature are good for your health. In one study, hospital patients with a view of trees had shorter hospital stays and less need for pain medications. Another study indicated that prisoners with a view of the outdoors had fewer doctor visits.
“Why do we desire nature? Maybe we’re programmed to need it, since our ancestors’ survival was so dependent on their connection with nature,” suggests biologist E.O. Wilson.

People have been growing chrysanthemums(菊花)for more than 2,000 years. Mums make bright and colorful gardens. People in China and other Asian cultures make tea with the flowers.
One basic kind of mum is the garden mum. The other basic kind is the florist mum. The garden mum is better able to handle different growing conditions.
There are many varieties of mums. The decorative mum is often seen in gardens. Another popular type, the quill mum, has long, straight petals(花瓣)like a tube or needle.
Chrysanthemum blooms can be white, yellow, gold, red or other colors. The plants often grow one meter high.
The soil for chrysanthemums should be kept moist but well drained so it does not get too wet.
Newly-planted mums should be watered two or three times a week, depending on conditions. Plants established in the ground may do well just with normal rainfall.
Mums grow best in full sunshine. They produce colorful blooms when days get shorter and nights get longer. The life cycle of the plant depends on the amount of daylight. This is why experts advise against placing mums near night lights or street lights. The light may interfere with their normal growth cycle. The plants may develop buds too soon.
In climates where temperatures fall below freezing, plant mums at least six weeks before the first frost. That way, the plants will be well established for cold weather.
Some gardeners say the most beautiful presentation comes from planting mums close together. But be sure to leave enough space to let air flow between the plants. If not, there may be a greater chance of disease.
To get more blooms, gardeners pinch(掐)back the branches when new growth has reached fifteen centimeters. Squeeze about five to seven centimeters off each branch. Pinch it again when a branch grows another twelve to fifteen centimeters. Stop the pinching about one hundred days before you want the plants to bloom.
【小題1】 What has a great effect on the life cycle of the mum?

A.The conditions of the soil.B.The amount of daylight.
C.The amount of rainfall.D.Cold weather.
【小題2】Why do gardeners pinch back the branches when new growth reaches certain length?
A.To make mums grow thick.B.To get more blooms.
C.To prevent mums from falling ill.D.To let air flow between the plants.
【小題3】 Which of the following is true according to the passage?
A.Growing mums has a very long history and all the people in the world like making tea with mums.
B.Mums can grow one meter high and the closer they are planted, the higher they grow.
C.Though planting mums close together can make them look more beautiful, enough space should be left.
D.The petals of mums are long and straight and the more water mums get, the more quickly they grow.
