Can animals be made to work for us?Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings. They point out that at a circus,for example,we may see elephants,monkeys,dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely,you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them. Of course,as we know,dogs can be used to guard a house,and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia,for example,pigeons which are birds with good eyesight,are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others,it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour. Apes have been used in America in helping to make cars,and scientists believe that these large monkeys may be one day gather crops and even drive trains. Which of the following is not true?
A、Scientists consider apes may drive trains some da
B、Apes have worked in some factorie
C、Apes may one day be used to gather crop
D、An ape is not a large monke
【正确答案】：D
【题目解析】：根据文章的内容，我们来逐一分析选项： A选项：“Scientists consider apes may drive trains some day”，这个选项与文章中的“scientists believe that these large monkeys may be one day gather crops and even drive trains”相吻合，所以A选项是真实的。 B选项：“Apes have worked in some factories”，虽然文章中提到在美国有猴子被用来帮助制造汽车，但并没有明确说是在工厂工作，但从广义上讲，这可以被看作是“在工厂工作”的一种形式，因此B选项可以被认为是真实的，尽管略有模糊。 C选项：“Apes may one day be used to gather crops”，这与文章中的“scientists believe that these large monkeys may be one day gather crops”直接对应，所以C选项是真实的。 D选项：“An ape is not a large monkey”，这个选项与文章中的描述不符。文章中明确提到“apes”（猿）是“large monkeys”（大猴子）的一种，因此D选项是不真实的。 综上所述，不真实的选项是D。
