Sports and games make our bodies strong, prevent us from getting too fat, and keep us healthy. But these are not their only use. They give us valuable practice in making eyes, brain and muscles work together. In tennis, our eyes see the ball coming, judge its speed and direction and pass this information on to the brain. The brain then arms, legs, and so on, so that the ball is met and hit back where it ought to go. All this must happen with very great speed, and only those who have had a lot of practice at tennis can carry out this complicated chain of events successfully. For those who work with their brains most of the day, the practice of such skills is especially useful.

Sports and games are also very useful for character-training. In their lessons at school, boys and girls may learn about such virtues as unselfishness, courage, discipline and love of one's country; but what is learned in books cannot have the same deep effect on a child's character as what is learned by experience. The ordinary day-school cannot give much practical training in living, because most of the pupils' time is spent in classes, studying lessons. So it is what the pupils do in their spare time that really prepares them to take their place in society as citizens when they grow up. If each of them learns to work for his team and not for himself on the football field, he will later find it natural to work for the good of his country instead of only for his own benefit.

(1)Besides keeping us healthy, how many other good points of sports and games are mentioned in the passage?

A、One.

B、Two.

C、Three.

D、Four.

(2)The topic sentence of paragraph 2 is ().

A、Sports and games are also very useful for character-training

B、The ordinary day-school cannot give much practical training in living

C、What the pupils do in their spare time prepares them to take their place in society as citizens

D、None of the above

(3)The main idea of paragraph 1 is ().

A、Sports and games make our bodies healthy

B、Tennis is a very good sport

C、Tennis is a very fast sport

D、Sports and games help us practice many parts of our bodies together.

(4)The word “effect” in paragraph 2 line 3 may mean ().

A、affect

B、fact

C、result

D、act

(5)According to the passage, if a child learns to work for his team on the football field, he will later ().

A、become a football star

B、win a football match

C、work for his own benefit

D、work for the benefit of his country

    B.U=US+R×I
    C.U=?US?R×I
    D.U=?US+R×I

    答案:B
    解析:
    电压与电流为非关联参考方向,在电压与电流的表达式中使用负号。因此,端口电压U=US?R×(?I)=US+R×I。该题还可以从电压、电流的的参考方向与实际方向的关系这一角度考查。出题陷阱:二端口的电压方向与电压方向一致,因此C、D错误;参考电流方向与参考电压方向不一致,因此A错误。部分同学误选择A,未能理解非关联参考方向的意义。
