第1题：

下列程序的执行结果是______。 include include using namespace std; vo

下列程序的执行结果是______。

include＜iostream.h＞

include＜iomanip.h＞

using namespace std；

voidmain()

{

cout＜＜setfill('x')＜＜setw(10)；

cout＜＜"Hello"＜＜end1；

}


正确答案：xxxxxHello
xxxxxHello 解析：此题考查的是I/O的格式化输出。Setfill('x')表示填充字符为V，并且一直有效；setw(10)表示将输入输出的宽度设置为10，宽度设置的效果只对以此次输入或输出有效，在完成一个数据的输入或输出后，宽度自动恢复为0；题目中字符串“Hello”的宽度不够10，所以其前面将有5个填充符V。

第2题：

应在下列程序画线处填入的正确语句是 ( )。include using namespace std;clas Base{pu

应在下列程序画线处填入的正确语句是 ( )。 #include ＜iostream＞ using namespace std; clas Base { public: void fun() { cout＜＜"Base::fun"＜＜end1; } }; class Derived : public Base { void fun() { ________________//显示调用基类的函数 fun() cout＜＜"Derived::fun"＜＜end1; } };

A．fun();

B．Base.fun();

C．Base::fun();

D．Base-＞fun();


正确答案：C
解析：作用域分辨符号是“::”，它可以用来限定要访问的成员所在的类的名称。在派生类Derive的定义中显式调用基类的函数fun()，则只能借助于作用域分辨符“::”。

第3题：

The students complained about the () rules and regulations at the school.

A、rigid

B、regulate

C、severe

D、serious

Cell Phones: Hang Up or Keep Talking?

Millions of people are using cell phones today.In many places it is actually considered unusual not to
use one.In many countries,cell phones are very popular with young people.They find that the phones are
more than a means of communication一having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some
doctors are concerned that in the future many people may suffer health problems from the use of mobile
phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried
about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your
health.
On the other hand,why do some medical studies show changes in the brain cells of some people who use
mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
（扫描）equipment. In one case , a traveling salesman had to, retire at a young age because of serious memory
loss.He couldn't remember even simple tasks.He would often forget the name of his own son.This man
used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of
years.His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines
can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is
some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need
it. Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
phone too often.

The writer's purpose of writing this article is to advise people______________.
A:to buy mobile phones
B:to update regular phones
C:to stop using mobile phones
D:to use mobile phones less often

答案：D
解析：
由第一段可知，人们买手机是因为它流行，从最后一段第四句可知，买手机是因为它方便又实用。
detect意思为“发现，找到”,discover的意思与之一样。
由第三段的第三、四句话可知，这个商人很年轻就退休是因为他丧失了记忆力，连简单 的任务都记不住了。
由第四段的最后一句话可知，手机公司认为手机的辐射很小，不足以对人们的健康造 成伤害。
由最后一段第一句话可知，作者的写作目的是劝我们最好少用手机。 第二篇 文章主要介绍了EoL这一工程的相关信息。

第8题：

下面程序的执行结果是______。 include include using namespace std; vo

下面程序的执行结果是______。

include＜iostream.h＞

include＜iomanip.h＞

using namespace std；

void main()

{

cout＜＜setfill('x')＜＜setw(10)；

cout＜＜"Hello"＜＜endl；

}


正确答案：xxxxxHello
xxxxxHello 解析：本题考核I/O的格式化输出。setfill('x')表示填充字符为'x'，并且一直有效，直到再次设置填充字符为止。setw(10)表示将输入输出宽度设置为10，当实际数据宽度小于指定的宽度时，多余的位置用填充字符填满；当实际数据的宽度大于设置的宽度时，仍按实际的宽度输出。宽度设置的效果只对一次输入或输出有效，在完成一个数据的输入或输出后，宽度设置自动恢复为0(表示按数据实际宽度输入输出)。题中字符串“Hello”的宽度不够10，所以其前面将有5个填充符 'x'。
