    Passage Five

    In America, every student in his or her second year of high school is required to take a class in driver's education.

    The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.

    After a student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver's test. The person must pass all three tests in order to be given a driver's license. If the person does well in his or her driver's education class, he or she will pass the test with flying colors and get a driver's license.

    51. In America, the driver's course mentioned above______.

    A. is considered as part of the advanced education

    B. is given to anyone wanting to get a driver's license

    C. is carried on after students graduate from high school

    D. is offered to all the students of Grade 2 in high school

    问答题
    While some people claim that a person's essential qualities are inherited at birth, others hold that the circumstances in which a person grows up are mainly responsible for the type of person he/ she later becomes. Write a composition of 400 words on the following topic, expressing your views

    正确答案：
    ESSENTIAL QUALITIES: INHERITED OR NOT? Generally, opinions differ with regard to the formation of people's essential qualities. Some people claim that a person's essential qualities are inherited; others hold that the circumstances in which a person grows up are mainly responsible for the type of person he later becomes. These two kinds of opinions, to a certain degree, are equally reasonable. Personally I think circumstances are more important than inherited characteristics for the following reasons.
    True, inherited characteristics play an important role in the formation of one's essential qualities. Cases abound in which children are exactly like their parents in many aspects. The role inherited characteristics play should not be denied. Otherwise, how could we explain the proverb like father, like son? But the son of a criminal may not be a criminal like his father. He might become a scholar of respectable moral integrity. And the son of a scholar might end up as a criminal, not a scholar. In many cases, the circumstances in which a person grows up are responsible for the type of person he later becomes. If inherited characteristics were the overriding factor in shaping a person's essential qualities, then the sons of the great Chinese poets Li Po and Du Fu would also be great poets, and the sons of great scientists would be great scientists.
    What is more, even the same person, having experienced the ups and downs of life, would change dramatically in his essential qualities. For instance, a college student, having experienced the agonies of his parents' decade-long separation or divorce, grows up from a carefree boy to a taciturn adult. Indifferent to things around him, he may hold a negative attitude toward people and society. On the contrary, if he is lucky enough to have a happy family, and there is no other worries and troubles, he will most possibly live a happy life as before. In his case, circumstances are the most powerful shaping force in the formation of his essential qualities.
    To be honest, it is not easy to reach a final conclusion about this question, because the formation of one's essential qualities is a highly complex matter. There is no denying that one's essential qualities are inherited to a large extent. But, based on the above instances, I may well say that circumstances play a bigger role in shaping a person's essential quality.
    解析：
    从文章第一段结尾可知，作者认为环境比先天因素更能影响人的成长。第二段通过举例证明先天因素不起决定性作用。第三段通过对比法来说明环境对人的巨大影响。结尾段重申论点。

    B．this (Person(n，A))；

    C．this(n，A)；

    D．this(name，age)；


    正确答案：C
    解析：本题主要考查在同一个类的不同构造方法中调用该类的其他构造方法需要使用 this(…)的形式，而且必须是在构造方法的第一行调用。这个和普通方法重载调用的方式不同，普通方法可以直接使用方法名加参数来调用，而且调用位置没有限制，因此选项A是不行的，选项B的语法就是错误的，选项D的错误在于在父类型的构造方法被调用前不能引用类的成员。构造方法是一个类对象实例化的开始，因此在构造方法中不能将成员作为参数引用。
