D Honeybee populations have been mysteriously decreasing all over the world. However, what is actually causing the bees to die out? This, considering honeybees are responsible for pollinating well over 100 different fruits and vegetables, would be absolutely devastating for humankind. Are humans actually any closer to finding a solution that will stop the species from becoming extinct? In 2013, as many scientists believe that the use of pesticides and chemicals on crops is one of the reasons for the decline in bees, many countries in Europe have banned the use of many dangerous chemicals and pesticides on crops that honeybees are attracted to. A March 2013 report stated that scientific studies had shown that many pesticides could affect the memory of honeybees, which means that when exposed to pesticides, they will simply forget where their nest is and never return home again and die out in the open. This would explain the lack of dead bodies. If a honeybee was to forget the location of its nest, fly away into a forest and die of confusing exposure, it is only natural that the bee owner would never see that bee again. Another danger to the species actually isn’t made by humans. Known as a “Zombie Fly Parasite , this infectious strain is passed onto the bodies of honeybees by flies. This infection takes control of the bee, “turning it into a zombie , and while being controlled from within, the parasite fly and its larvae will then infect other hosts, effectively turning them into mindless zombies. With new studies showing possible causes of the dying honeybee population, will mankind now take action to prevent the endangered species from completely dying out? 47. The underlined word in the passage probably means “ . A. beneficial B. important C. damaging D. necessary 48. Why did bee owners not find the dead bodies of bees? A. Because the bees lived their new lives in a forest. B. Because pesticides dissolved the dead bodies. C. Because the bees lost memories and died in the wild. D. Because the Zombie Fly Parasites killed the bees. 49. Zombie Fly Parasites . A. are carried by plants B. are mindless bees C. can infect other parasites D. can control bees 50. What is the best title of the passage? A. The honeybee population is decreasing B. What’s killing off the honeybees? C. How to stop the decrease of bee D. Take action to protect the honeybees 查看更多

Language is the most astonishing behavior in the animal kingdom. It is the species-typical behavior that sets humans completely   36   from all other animals. Language is a means of   37   , but it is much more than that. Many animals can   38   . The dance of the honeybee communicates the location of flowers   39   other members of the hive (蜂群). But human language permits communication about anything,   40   things like unicorns (独角兽) that have never existed. The key   41   in the fact that different words can be   42   together in different ways, according to   43   to communicate different meanings.

Language is the most important learning we do.

The speaker has to translate thoughts into  49   language. Brain imaging studies suggest that the time from thoughts to the   50   of speech is extremely fast. Only 0.04 seconds! The listener must hear the sounds to   51    what the speaker means. He must use the sounds of speech to   52   the spoken words, understand the pattern of   53   of the words (sentences), and finally   54   the meaning.

Honeybees
Honeybees can do three kinds of jobs.
It is one of the most unusual insects in the world. Bees are special because they divide up their honeybee work. Each bee has a certain job to do.
The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.
Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.
The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day.
【小题1】The bee’s nest is called a _______.    

A.hive B.honeycomb C.drone D.wax
【小题2】Which jobs do workers do?
A.They lay 2, 000 eggs each day and build a nest.

Wild elephants that destroy crops and damage trees are a serious problem in many parts of Africa . But there could be a simple and relatively safe way to stop them in their tracks , by employing the talents of the tiny African honeybees .

       The number of elephants in Kenya has risen over the past ten years , with some disastrous results . Not only do these huge animals attack local farms , but they step someone to death an average of once every two weeks . Now a biologist has discovered a possible threat : the elephants are extremely aware of trees that house honeybee hives .

       “I an puzzled why nobody has thought of this before , ” says Fritz Vollrath at the University of Oxford . “ When an elephant knocks a beehive he runs and the bees will follow him or miles . ” He says that placing hives of the honeybees around local farms and fragile habitats could be an effective way to threaten the animals .

       Volirath put 30 unoccupied and 6 occupied beehives in some of the growing on a bush frequently damaged by elephants on Laikipia Plateau in Kenya . On average the elephants attacked 9 out of 10 trees that didn’t have hives , severely damaging a quarter . But they steered clear of all six trees with occupied hives . The elephants also left alone one-third of the trees with empty hives , suggesting that some had learnt not to take the risk .

       The bees threaten elephants by stinging vulnerable (易受伤)areas such as the eyes , belly , behind the ears and under the trunk . People could be at risk from the bees , admits Voilrath , but that may be outweighed by the risk of being killed by an elephant . Another experiment by Voilrath shows that elephants also avoid the sound of angry bees played from a loudspeaker .

1.What harm do the wild elephants in Africa do ?

       A.Killing local people                                     

B.Damaging beehives

C.Threatening animals                                   

D.Destroying villages

2.What can we learn from the underlined sentence ?

       A.They ran away from the trees with empty hives on it

B.They tried not to touch the trees with hives full of bees

C.They kept a distance from al the trees with hives on them .

D.They were clear that all the six trees were occupied by hives

3.What’s Volirath’s another experiment on this elephant’s case ?

       A.Let bees attack and kill elephants one by one

B.Encourage bees to sting elephants’ eyes and ears

C.Use the bees’ sound to drive elephants away

D.Employ tiny African honeybees to threaten elephants

4.From the passage we can conclude that _______

       A.there is always one thing to bet another

B.little bees can kill big and wild elephants

C.serious problems often come up in Africa

D.elephants enjoy attacking people and farms
