第1题:

We often speak of language as a vehicle of expression a metaphor that can illumine many aspects of our foreign language teaching situation, Language is a vehicle of meaning that we do not even realize we are using,in other words, a vehicle that is transporting a person's message somewhere but is not itself the object of the trip.


正确答案:我们经常说语言是一种工具,这种比喻可以启发我们在外语教学的许多方面,语言是我们甚至没有意识到的、正在使用的工具。换言之,语言这个工具是将人们的信息传递到别的地方,而语言并不是这个“旅程”的目的。

第6题:

使用VC6打开考生文件夹下的工程test17_1,此工程包含一个源程序文件test17_1.唧,但该程序运行有问题,请改正程序中的错误,使程序的输出结果如下:

Vehicle message

Car message

Vehicle message

源程序文件test17_1.cpp 清单如下:

include <iostream.h>

class vehicle

{

int wheels;

float weight;

public:

/***************** found *****************/

void message(void){ cout<<"Vehicle message\n";}

};

class car:public vehicle

{

int passenger_load;

public:

/***************** found *****************/

void message (void){cout>>"Car message\n";}

};

class truck:public vehicle

{

int passenger_load;

float payload;

public:

int passengers(void){return passenger_load;}

};

void main()

{

vehicle * unicycle;

unicycle=new vehicle;

/***************** found *****************/

unicycle.message()

delete unicycle;

unicycle=new car;

unicycle->message();

delete unicycle;

unicycle=new truck;

unicycle->message();

delete unicycle;

}


正确答案:(1)错误:void message(void){cout"Vehicle message\n";} 正确:virtual void message(void){cout"Vehicle message\n";} (2)错误:void message(void){cout>>"Carmessage\n”;} 正确:void message(void){eout"Carmessage\n";} (3)错误:unicycle.message(); 正确:unicycle->message();
(1)错误:void message(void){cout"Vehicle message\n";} 正确:virtual void message(void){cout"Vehicle message\n";} (2)错误:void message(void){cout>>"Carmessage\n”;} 正确:void message(void){eout"Carmessage\n";} (3)错误:unicycle.message(); 正确:unicycle->message(); 解析:(1)主要考查考生对于虚函数使用规则的掌握,要实现对函数message的动态联编应该使用虚函数,否则产生的是静态联编,调用的函数输出结果就与要求不符;
(2)主要考查考生对于流输出操作的掌握,该处错误的使用了流输入操作;
(3)主要考查考生是否能分清对象和对象指针,对象指针使用“->”调用成员函数,而对象使用“.”调用成员函数。

第7题:

若已定义了类Vehicle,则下列派生类定义中,错误的是

A.class Car:Vehicle{/*类体略*/);

B.class Car:public Car{/*类体略*/);

C.class Car:public Vehicle{/*类体略*/);

D.class Car:virtual public Vehicle{/*类体略*/);


正确答案:B
解析:派生类从基类的继承方式有3种:公有继承(public)、私有继承(private)和保护继承(protected)。如果不显式地给出继承方式,默认的类继承方式是私有继承,ACD项正确。类的继承是新的类从已有类那时得到已有的特性,故B项错误。
