That year, in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child that anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty comers, etc.
Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes.
Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff: sweets, playing cards, oranges, paper planes, etc. It didn′t seem like any of this bothered the new kid.
However, little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him.
It was the new teacher!
The teacher gave the new kid a hug, and off they went, hand in hand. Following from a distance, Lewis could hear they were talking about math.
What does the passage imply?

A.The stupid student was not good at math.
B.The stupid student was by no means slow in math.
C.The stupid student had no gift for math and was slow in math.
D.The stupid student disliked both the new math teacher and his lessons.

Some young soldiers who had recently joined the army were being trained in modern ways of fighting,and one of the things they were shown was how an unarmed man could trick an armed enemy and take his weapon away from him．First one of their two instructors took a knife away from the other,using only his bare hands;and then he took a rifle away from him in the same way．After the lesson,and before they went on to train the young soldiers to do these things themselves,the two instructors asked them a number of questions to see how well they had understood what they had been shown．One of the questions was this:“Well,you now know what an unarmed man can do against a man with a rifle．Imagine that you are guarding a bridge at night,and that you have a rifle．Suddenly you see an unarmed enemy soldier coming towards you．What will you do?”
The young soldier who had to answer this question thought carefully for a few seconds before he answered,and then said,“Well,after what I have just seen,I think that the first thing I would do would be to get rid of my rifle as quickly as I could,so that the unarmed enemy couldn't take it from me and kill me with it!”

The soldiers practiced__.

A.before being instructed
B.after being instructed
C.while being instructed
D.two days later

Popular British author,Charles Dickens′（1812--1870）family could hardly make ends meet.They could only afford to send one of their six children to school.Dickens was not that child.His parents chose to send a daughter,who had a talent for music,to an academy.Then at the age of 12,Dickens′life took another turn for the worse.
His father,a clerk,was placed in prison for unpaid debts.And,being the oldest male left at home,Dickens took up work at a factory.His horrible experience there became the fuel for his future writing.His father was freed three months later and inherited a small amount of money.Dickens was then sent to school.
From 1836 to 1837,he wrote a monthly series of stories.Thus The Pickwick,Papers,came into being,which brought fame to him.
Throughout his career,Dickens covers various situations in his novels.He wrote about the miserable lives of the poor in Oliver Twist,the French Revolution in Tale of Two Cities,and social reform in Hard Times.He also wrote David Copperfield,a book thought to be modeled on his own life.
"I do not write bitterly or angrily,for I know all these things have worked together to make me what I am,"he once said.His difficult childhood did indeed shape the person he became,as well as his writing career.There are shades of young Dickens in many of his most beloved characters,including David Copperfield and Oliver Twist.
Like the author,all these characters come from poor beginnings and are able to rise above their setbacks and achieve success."Minds,like bodies,will often fall into an ill-conditioned state from too much comfort,"he once wrote.On June 9th,1870,aged 58,Dickens died,leaving one unfinished work.The words on his tombstone read:"He was a sympathizer to the poor,the suffering and the oppressed,and by his death,one of England′s greatest writers is lost to the world."

B.He felt it a pity that things weren't in his favor.
