从下列2道试题(试题5至试题6)中任选1道解答。如果解答的试题数超过1道,则题号小的1道解答有效。
阅读下列说明、图和C++代码,将应填入 (n) 处的字句写在答题纸的对应栏内。
[说明]
已知对某载客车辆(Car)进行类建模,如图5-1所示,其中类Engine表示发动机引擎,类Wheel表示车轮,类Body表示车身,类Driver表示司机,类Passenger表示乘客。


[C++代码]
const int (1) =7; //定义最多载客数
const int MAX WHEELS=5; //定义最多轮胎数
class Body{
//此处代码省略
}; //车身类
class Passenger{
//此处代码省略
}; //乘客类
class Wheel{
//此处代码省略
};//车轮类
class Driver{ //司机类
public:
string name;//表示第几路公交车司机
Driver(string driverName):name( (2) ){}; //构造函数
};
class Engine{ //引擎类
public:
string engineNo; //引擎编号
Engine(string engineNo){ (3) ->engineNo=engineNo;} //构造函数
};
class Car{ //汽车类
protected:
Engine * engine; Driver * driver; Body body;
Wheel * wheels[MAX_HEELS]; Passenger * passengers[MAX_PASSENGERS];
public:
Car(Driver * driver){//构造函数
this->driver=driver;
engine=new Engine("TX6536型号引擎");
int index;
for (index=0; index<MAX_HEELS; index++){
wheels[index]=new Wheel();
}
for(index=0; index<MAX_PASSENGERS; index++){
passengers[index]=NULL;
}
}
virtual~Car() {//析构函数
for (int index=0; index<MAX_WHEELS; index++)
delete wheels[index];
delete (4) ;
}
int getPassengerNumber(){//获取车上乘客数量
//此处代码省略
}
void getOnPassenger(Passenger * aPassenger){//乘客上车
//此处代码省略
}
void run(){//开车
if(driver==NULL) { cout<< "司机尚未上车!"; return; }
//此处代码省略
}
);
void main(){
Driver driver("第五路公交车司机");
Car car ( (5) );
Passenger passengers [MAX_PASSENGERS];
for (int index = 0; index<MAX PASSENGERS; index++) //乘客上车处理
car.getOnPassenger(&passengers[index]);
car.run();
}

Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose. Most people recover from fever and   1  symptoms within a week without requiring medical attention. But influenza can 2  severe illness or death in people at high risk. The time from infection to illness is about two days.

Yearly influenza epidemics can  3  affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of  4  age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.

Seasonal influenza  5  easily and can sweep through schools, nursing homes or businesses and towns. When an  6   person coughs, infected droplets get into the air and another person can breathe them  7   and be exposed. The virus can also be spread by hands infected with the virus.  8   transmission, people should cover their mouth and nose with a tissue when coughing, and  9  their hands regularly.

Drugs for influenza are   10  in some countries and effectively prevent and treat the illness. Some influenza viruses develop  11   to the antiviral medicines, limiting the effectiveness of treatment.

Influenza epidemics occur    12  during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million   13    of severe illness, and about 250 000 to 500 000 deaths.

Influenza can cause serious public health and economic problems. In   14   countries, epidemics can result in high levels of worker absenteeism and productivity  15  .   16   most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many   17   die from the disease every year.   18    is known about the effects of influenza epidemics in developing countries.

The most    19  way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care  20   high risk individuals.
