What is an ocean like?

Bubbles rise. Before your eyes is a world of color and beauty. There are colorful fish, coral (珊瑚), and other forms of ocean life. Its coral can be millions of years old. Its Earth’s largest environment—the ocean.

An ocean is a large body of salt water. Earth has five oceans that are all connected (连通). They cover more than 166 million square kilometers, or about one-third of the Earth. The Pacific Ocean is the largest. Millions of living things are found in Earth’s oceans. Almost all ocean life forms live in shallow (浅) waters that are 100 meters deep or less. Yet, most of the world’s oceans can be as deep as 1,500 meters or more. The bottom of the ocean is too cold and dark to support much life.

____________

Of all the animals in the ocean, the number of fish is the largest. Ocean animals have their own ways that help them live in their environment.

The ocean is a wild place. Animals live in a changing environment. Some small fish feed on plants, and large fish eat smaller fish. Still larger animals, such as sharks, rule the underwater animal world. So how do animals stay safe in this environment?

Some fish have special tails. Waving their bodies, they can swim quickly along the ocean floor. If a stingray (黄貂鱼) senses danger, in just a few seconds it will cover itself with some sand. Its skin is the same color as the sand. This camouflage is a way that the stingray and some other ocean animals stay safe under water.

A.Most animals live near the bottom of the ocean.
B.The Pacific Ocean covers one-third of the Earth.

We have known for a long time that flowers of different plants open and close at different time of day. This is so familiar that there seems to be no need to ask the reason for it. Yet no one really understands why flowers open and close like this at particular times. The process (过程) is not as simple as we might think, as recent experiments have shown. In one study, flowers were kept in constant (连续的) darkness. We might expect that the flowers, without any information about the time of day, did not open as they normally do. In fact, they continued to open at their usual time. This suggests that they have some mysterious (神秘的) way of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of “inner clock”.

This discovery (发现) may not seem to be very important. However, it was later found that not just plants but also animals —including man —have this “inner clock” which controls the working of their bodies and influences (影响) their activities. Men, then, are also influenced by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.

In the past, this did not matter very much because people lived in natural condition. In the modern world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very useful, then, to know more about the “inner clock”. Such ordinary things as flowers might help us understand more about ourselves.

A.different flowers open and close at different times of day
B.for their opening and closing, flowers do not need information from the outside world
C.flowers are influenced by weak light even when they are in a dark room
D.flowers can be used for telling the time
【小题2】The “inner clock” _________________________.
A.is an unimportant discoveryB.is only found in animals
C.has not been understood by farD.has an effect on human life
【小题3】Further study of the “inner clock” will be useful because ________________.
A.it might help us in some way
B.we do not yet understand plants and animals well enough
C.the number of spacemen and airplane pilots is fast increasing
D.we should try to live more naturally than we do now
【小题4】Kept in constant darkness, flowers ________________________.
A.will not open or close as usualB.will not open any longer
C.will open as they do in natural conditionsD.will always remain in full blossom (开花)
【小题5】________________ have a mysterious power of knowing time without information from the outside world.
A.Animals including man as well as plantsB.All living things except man
C.Flowers are the only things in the world thatD.Neither animals nor plants
