At the beginning of this century, medical scientists made an interesting discovery: we are built not just of flesh(肌肉) and blood but also of time. They were   41   to show that we all have a ‘body clock’   42   us, which controls the   43   and fall of our body energies,   44   us different from one day to the next.

The   45   of a ‘body clock’ should not be too   46   since the lives of most living things are controlled   47   the 24-hour night-and-day cycle(循环). We feel   48   and fall asleep at night and become   49   and energetic during the day. If the 24-hour cycle is   50   most people experience unpleasant   51  . For example, people who are not   52   to working at night can find that   53   of sleep causes them to   54   badly at work.

  55   the daily cycle of sleeping and   56  , we also have other cycles which   57   longer than one day. Most of us would   58   that we feel good on some days and not so good on   59  ; sometimes our ideas seem to flow and at other times, they   60   do not exist.

    At a few minutes past five, Dave noted that the blanket of darkness was lifting. He was just able to make out the heavier masses that eventually appeared as the familiar trees that lined the road at the base of the hill. The upper reaches of the sky showed lighter shades of gray.

    Dave got out of bed quietly and dressed quickly. He mixed a spoonful of instant chocolate into a glass of cold water, and his impatience forced him to finish the drink in gulps.

    As he walked down toward the lake, Dave paused to reach for the fishing pole and gear box on the bench where he had left them the night before.

    By the time he reached the small boat, a thick white mist (雾气) had spread over the surface of the water. He stepped into the boat, sat down, and rowed out of the weed beds that lined the edge of the shore.

    The outer fringe (边缘) of the lake disappeared as the boat moved forward noiselessly. All he could see was the enveloping whiteness. He could not tell where the boat and the surrounding air met the surface of the lake.

    Dave rowed steadily ahead, relying on a mental picture of the surroundings. Then the mist began to rise, slowly. It soon rested inches above the still surface of the lake. The heavy silence was now being broken by the fish breaking through the surface as they leaped out of the water for low-flying insects.

    The magic time had arrived. Dave raised his pole. Dawn was broken. He was excited with expectancy.

39. Dave got up early in the morning to ______

    A. enjoy the scene of the lake                       B. seek adventure at the lake

    C. go fishing in the lake                               D. take a walk by the lake

40. According to the story, which of the following is TRUE?

    A. Dave broke the quietness of the lake.         B. Dave was familiar with the surroundings.

    C. Dave took a picture of the lake with him.   D. Dave forgot the fishing pole at the beginning.

41. The underlined word “It” in Paragraph 6 refers to ______

    A. fish                   B. boat                        C. silence              D. mist

42. What can we learn from the end of the story?

    A. Dave was hopeful of catching a lot of fish.       B. Dave wished the weather would be better.

    C. Dave was happy that dawn was broken.     D. Dave expected someone else would come.

   At a certain time in our lives we consider every place as the possible sites(地点) for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.

   The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I gave for it.

   The real attractiong of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition fo the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apples trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.

   I was not really troubled by the loss. I had always had a garden, but I don’t thing I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted (无牵挂的). It makes but little difference whether you own a farm or not.

All plant cells are able to take up water. Even dead ones do to a certain degree. Absorption of water by dead cell walls makes wood swell(肿胀). In common land plants, the living cells of roots take up most of the water. Land plants without roots do exist, however. Those greenish-yellow lichens(苔藓)you see on tree trunks and on rocks in the high mountains have no roots. Half a billion years ago, when water plant started to invade the land, the first primitive land plants did not have roots; they were marsh (沼泽) plants.

Even among the flowering plants, one finds rootless forms. These flowering plants are the so-called higher plants because they evolved more recently and are thus considered higher on the evolutionary scale. In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water exclusively from the dew it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

Wood swells because of _______.

A. the dead cell walls          B. tiny drops of water entering the dead cell

C. the growth of the cell       D. the death of the cell

From the passage we know that the evolutionary scale is arranged according to ______.

A. evolutionary cycles                  B. heights and depths

C. time                                D. kinds

The bromeliad is a plant that _______.

A. has useless roots             B. is a pineapple

C. can grow anywhere           D. takes up water through its leaves

Which of the following is NOT true?

Water plants existed before land plants.

Only living plant cells take up water.

The greenish-yellow lichens are uncommon land plants.

The living cells of roots absorb more water than the rest of the plant.

The most suitable title for this passage is ______.

A. water intake by cells  B. rootless plantsC. plant in the desert   D. higher plants
