英语看图作文语句【一】
In this picture, we can tell that the son is talking to his father about his concern about the nuclear waste. His father told him that if he can empty the dustbin first, he can do anything. This is an easy but very important story, telling us that we have to focus on things around our daily life first, and then the things great enough in the world.
In our daily life, it is very common to find some people that talk about their great minds on topics that far away from their lives. However, they provide little concern on staffs that around their own daily lives. These people are usually not very successful because their minds are beyond their grasp. To this end, students who want to be a better man, have to know that one can become greater and greater if they can complete things around their daily life well one by one. They may stand on the top of the mountain in the society finally.

C语言while、do-while、for循环课程5
课程3中，提到C语言基本语句分为：数据定义语句，数据处理语句
数据处理语句又可分为：表达式语句，函数调用语句，空语句(;，复合语句，流程控制语句。
流程控制：指程序代码执行的顺序。流程的分类：顺序、选择、循环。
C语言的循环结构通过三种语句来实现，即while、do-while、forWhile语句的一般形式while(循环条件表达式循环体语句；
功能：当循环条件表达式为真，执行循环体语句，执行完了，再判断条件表达式是否为真，为真，则再执行，直到条件表达式为假时，退出while循环。
实例1：用while语句求1~100的累加和。
#include//C语言编译预处理命令，文件包含为stdio.h
voidmain(//至少有一个用main(命名的主函数，返回值为void无值类型{
inti=1,sum=0;/*初始化循环，定义变量i和累加器sum，定义和之前，累加器清零*/
while(i<=100
{
sum+=i;//sum+=i是一个复合赋值运算符，等价于sun=sun+i;i++;
}
printf("1+2+3+...+100=%d ",sum;//输出十进制数，1加到100累加器的和}
MicrosoftVisualC++6.0运行结果
使用while循环时，一定要对循环条件表达式中出现的变量提前赋值，并在循环体内修改有关变量的值，以使循环能趋于终止。
While循环为当型循环，do-while循环也叫直到型循环。
do-while语句的一般形式为：
do
{
循环体语句}while(
循环条件表达式
实例2:用do-while编制一个求n!的程序，n的值由键盘输入。
#include
voidmain(
{inti=1,n,p=1;
printf("请从键盘输入一个数，进行连乘积: ";
scanf("%d",&n;
do
{p=p*i;
i++;
}while(i<=n;
printf("连乘积的结果为p=n!：%d ",p;
}
分析：此程序，先定义三个变量i、n、p,p从p乘1开始执行，再i进行自增1，循环体中的语句执行完毕后，判断while的循环条件表达式，当i自增1为2时，看2是否<=输入的n值，若为真，则继续返回do循环，直到i自增的值比n大，则退出循环。
do-while主要用于人机交互，do-while循环是先执行后判断，do里面的循环体至少被执行一次。区别于while是先判断循环条件表达式，后执行。
for循环也叫步长型循环
一般格式：for(表达式1；表达式2；表达式3循环体语句；
功能:先执行表达式1，再执行表达式2，如果表达式2的值为真，就执行循环体语句，最后执行表达式3.完成一次循环后，从表达式2执行，直到表达式2为假，退出循环。
实例3：参考实例1，用while求1~100的累加和，现在用for语句求1~100的累
加和。
#include
intmain(void
{
inti;intsum=0;
/*初始化循环，定义变量i
和累加器sum，定义和之前，累加器清零*/
for(i=1;i<=100;i++
{
sum=sum+i;
}
printf("sum=%d ",sum;
return0;
}
实例4：爱因斯坦的`阶梯问题：有一个长阶梯，若每步上2阶，最后剩1阶；若每步上3阶，最后剩2阶；若每步上5阶，最后剩4阶；若每步上6阶，最后剩5阶；只有每步上7阶，最后刚好一阶也不剩。请问该阶梯至少有多少阶。编写一个C程序解决该问题。
#include
main(
{intx;
for(x=7;;x+=7
if(x%3==2&&x%5==4&&x%6==5
break;
printf("Thenumberoftheladdersis：%d ",x;
}
分析：发现x一定是7的整数倍，可以依次递增地求出7的整数倍的值（7*1、7*2、7*3……），每求出一值，就用该值与2、3、5、6进行取模运算，最先得到的满足上述5个方程式的x值即为本题的答案。
用while语句，简单快速实现爱因斯坦的阶梯问题
#include
intmain(
{
inti=1;/*i为所设的阶梯数*/
while(!((i%2==1&&(i%3==2&&(i%5==4&&(i%6==5&&(i%7==0
++i;/*满足一组同余式的判别*/

last weekend we went to the countryside to have a picnic.we took several sandwiches and some bottles of water with us for lunch. of course we didn't forget to take some fruit and we even took some tomatoes and cucumbers.
we left home quite early in order to avoid the traffic jam.about two hours later, we came to a nice place. it was near a river. we put our bicycles under the trees and went swimming. it was a very hot day. the water was very refreshing.
after having a swim, we had lunch in the cool shade under the trees. then we went for a walk. we didn't come back home until the night fell.
上周末，我们去乡下野餐。我们带上了几个三明治和几瓶水午饭时吃。当然我们也没有忘记带上一些水果。我们甚至还带了几个西红柿和几条黄瓜。
为了避开交通高峰，我们很早就出发了。大约过了两个小时，我们来到了一个不错的`地方。它附近有一条河，我们把车子放在树下就去游泳。天气很热，河水使人振奋。
游完泳，我们在树荫下吃了午饭。然后我们去散步。直到夜幕降临，我们才回家。
it took us about two hours by bike to get to the nice place in the countryside. there was a rive there. the water was clean and it was a good place to swim. we threw our bikes on the ground
and jumped into the water. it was hot, but the water made us refreshed. after we swam around:'the river, we were tired.
we took out the sandwiches and water, and had our picnic in the shade under the trees. the most popular food are sausages and tomatoes.
after lunch we took a walk. there we saw many beautiful flowers and GREen grass. we smelled sweet air. how nice the picnic was!
我们骑车花了约两个小时，终于到了野外那个美丽的地方。那里有一条小河，河水清澈，真是个游泳的好地方。我们把自行车往地上一搁，就跳进河里。天气真热，河水让人感到舒爽。游了几个来回，我们有些累了。
我们拿出准备好的三明治和水，开始在树阴下野餐。最受欢迎的食品是香肠和西红柿。
午饭后，我们散步。在那儿我们看见许多漂亮的花和碧绿的草，我们闻到空气的芬芳。多么愉快的野餐啊!
英语看图作文语句【五】
The picture shows us a dialogue between a father and a son. The son told his father, “Dad, I’m a bit worried about disposing of nuclear waste”. While his father told him, “If you can empty the dustbin here you can do anything”. It reveals the importance of doing small things well before undertaking something big. There is also an old Chinese saying to go with this that a person can’t sweep the world before he can sweep his own room.
I agree on the point that it is of great importance for a person to do small things well before undertaking something big. First of all, doing small things well entail the qualities that needed in doing great things such as patience and ability of controlling time. For example, when we sweep our room, we need to manage our time and energy reasonably. Accordingly, if we sweep a bigger room, for example, a classroom with our classmates, we should learn how to cooperate and allot assignments as well. And a big advantage is that we can draw useful lessons from the failure of performing well because they didn’t cost a lot.
In another word, though these things seem trivial, they reinforce our manipulative ability and thus our understanding to the world. Therefore, we should not ignore the small things.

英语看图作文语句【七】
Just as is revealed in the picture above, the young, nowadays, just like the boy in the drawing, are prone to reach for what is beyond their grasp, but ignore the significance of doing something trivial and simple before accomplishing great feats.
There is no doubt that the symbolic meaning subtly conveyed in the picture should be given deep consideration. As we all know, a man who does not sweep a room, doesn't mention to sweep the world. In other words, the foundations of a building must be strong, or else the whole structure will fall down someday. Therefore, when it comes to the key to success, the most important thing lies in doing every tiny thing well around you.
As the saying goes, “the highest eminence is to be gained step by step.” To achieve the goal, not merely do we need ambition; we also need to realize the importance of dealing with triviality from the beginning. Only in this way can we get on the way to success down to earth.
