C

A blow-fly was looking for an ideal place like rotting meat to lay her eggs so that when her little babies were born, they could feed on the meat.

As she turned a corner in the grassland, she smelt something that smells like rotten meat in the air! With a great joy she landed on it and laid her eggs. She was happy that her children would have enough food to eat.

But the fly did not know she had made a great mistake. What she had sat upon was not meat but a flower, which smells badly. It is called a carrion flower. So, when the blow-fly’s eggs hatched and the little maggots（蛆）came out, they had nothing to eat. They died of starvation.

The carrion flower is one of the many flowers which send out dirty smells to attract flies. The Rafflesia stinks like rotting meat, while the tropical Lords and Ladies flower gives out a smell like rotting fish.

They do it for a special reason. These plants cannot move from their place. But it is important for the male cell of one plant to get in touch with the female cell of another plant. Once that is done, the seed of the plant will bloom and give birth to another plant.

The plant uses its stink to attract flies. As soon as the blow-fly sits on the follower, it is captured by the flower with strong hair. When the hair falls, the fly is free to fly- but it takes some pollen（花粉） with it. And goes and sits on another plant. The male cell of one plant meets the female cell of the other. The seed gets new life.

64. Why did the fly land on something smelly?

A. She was too careless before her bearing.       B. She liked the particular smell very much

C. She hoped to find some food for her babies.    D. She couldn’t find a better place for delivery.

65. The little maggots finally died because_________.

A. they were born too weak             B. they lacked food available

C. carrion flower were poisonous         D. their mother didn’t take care of them

66. Flowers like carrion flower and Rafflesia naturally smell terrible so that_________.

A. they need insects to spread their pollen     B. they succeed in producing more seeds

C. their seeds can be carried to other places    D. they can manage to absorb more nutrients

67. What is the best title of the text?

A. Dirty Tricks        B. Smelly Plants   C. A strange Flower   D. Secrets of Nature.

All penguins (企鵝) swim in cold waters and so need a good layer of insulation (隔離), some species come ashore in hot places.Humboldt penguins,for example,nest in arid hot - 40°C, deserts on the west coast of South America, while others survive the lowest temperatures of any animals.Male Emperor penguins,as we know, spend the Antarctic winters incubating eggs in temperatures that can fall below -70°C. The insulation is provided in layers, under the skin is a thick layer of fat, then there is a layer of downy feathers that trap air, and finally another layer of waterproof feathers that keep the cold water away from the skin. With all this insulation penguins have no problem keeping warm at temperatures down to about -10°C - although they have special adaptations of the circulatory system to keep their feet from freezing and to prevent much heat loss through the feet that are on the ice. At lower temperatures penguins have to huddle (蜷縮) together to keep warm. In such huddles the penguins gradually move from the hot interior to the cold outside so that every penguin has his turn in the middle and on the outside.

In hot climates, penguins suffer greatly from overheating. They use several strategies to lose heat. They puff up their feathers so that air can circulate to their skin; they hold their flippers（腳蹼）out from their bodies and pump hot blood to them so that they can act as radiators; they open their mouths and breathe to lose heat from their hot breath; and those species that live in hot climates also have several bare patches of skin around the eyes and feet, they send blood to these bare patches when they are hot - you can recognize a hot penguin since it will have pink eye patches and pink patches on its feet.

 

77. Which of the following are the ways for penguins to keep warm?

a. staying together in good social order 

b. several layers as radiators

c. a special circulatory system                    d. waterproof feathers

e. sending blood to bare patches

f. always staying in the middle

A. a, b, c                            B. a, c, d                           C. b, c, e                            D. c, d, f

78. The insulation consists of _______ layers.                                                      

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

79. The underlined "puff up" in the second paragraph can be replaced by ______.

    A. breathe deeply           B. blow up                        C. hold tight                     D. spread out

80. The passage mainly tells us ______.

    A. how penguins stay warm in cold places          B. that penguins are a clever animal

    C. how penguins keep their temperature            D. why penguins can live a safe life
