16.Homing pigeons are placed in a training program from about the time they are twenty-eight days of age.They are taught to enter the loft(閣樓) through a trap and to exercise above and around the loft and gradually they are taken away for short distance in wicker baskets and released.They are then expected to find their way home in the shortest possible time.
In their training flights or in actual races,the birds are taken to prearranged distant points and released to find their way back to their own lofts.Once the birds are liberated,their owners,who are standing by at the home lofts,anxiously watch the sky for the return of their entries.Since time is of the essence (本質(zhì)) the speed with which the birds can be induced to enter the loft trap may make the difference between gaining a win or a second place.
The head of a homing pigeon is comparatively small,but its brain is one quarter larger than that of the ordinary pigeon.The homing pigeon is very intelligent and will continue to the point of stubbornness (頑強(qiáng));some have been known to fly a hundred miles off course to avoid a storm.
Some homing pigeon experts claim that this bird is gifted with a form of built-in radar(雷達(dá)) that helps it find its own loft after hours of flight,for hidden under the head feathers are two very sensitive ears,while the sharp prominent (突出的) eyes can see great distances in daytime.
Why do homing pigeons fly home?They are not unique in this inherent skill; it is found in most migratory birds(遷徙,候鳥),in bees,ants,toads and even turtles,which have been known to travel hundreds of miles to return to their homes.But in the animal world,the homing pigeon alone can be trusted with its freedom and trained to carry out the missions that people demand.
51.What is the purpose of the passage?B
A.To convince the reader to buy a homing pigeon.
B.To inform the reader about homing pigeons and their training.
C.To protect homing pigeons against the threat of extinction.
D.To encourage the owners of homing pigeons to set the birds free.
52.According to the passage,what happens to homing pigeons when they are about a month old?C
A.They are kept in a trap.               B.They enter their first race.
C.They begin a training program.         D.They get their wings clipped and marked.
53.According to the passage,what is the difference between a homing pigeon and an ordinary one?D
A.The span of the wings.               B.The shape of the eyes.
C.The structure of the feathers.           D.The size of the brain.
54.Why does the author mention bees,ants,toads and turtles in the last paragraph?C
A.To describe some unusual kinds of pets.
B.To measure distances traveled by various animals.
C.To compare their home-finding abilities with those of homing pigeons.
D.To interest the reader in learning about other animals.

6.Last weekend we went mountain-climbing.Even the heavy rain in the morning could not prevent us go.Setting off very early,we went along an extreme narrow road,all in high spirits.On every side of the road were green fields and some farm house.We could hear the sound of the rain and our footsteps mixing with our laughter.At noon we reached top of the mountain.That surprised us most was the beauty of the scenes there.After having a short rest and sharing with the food we had brought,we started going down.It rained even harder.We are wet to the skin,and we still sang and laughed happily.

8.People will enjoy what you have to say if it is presented with humor.But,more importantly,if you are in a situation where important,and perhaps controversial(有爭議的),ideas must be presented to less than open minds,humor allows those ideas to be presented in a non-threatening (無威脅的) manner.Abraham Lincoln was famous for his ability to relate humorous stories to make a point.Humor used carefully throughout a presentation will also keep the listener's interest high.In a word,individuals learning how to use humor in their speeches can strengthen arguments,support interesting presentations and,most of all,entertain their audience in a positive and comfortable way.
