This is really a very fast game. Both sides are fighting for the ball all the time. We are enjoying every minute of it. Loud shouts can be heard here and there.

Willis has the ball now. This is only his third game for England, but he's playing so well that it won't be his last, I'm quite sure.

Willis passes the ball to Cotton. Cotton kicks it over the heads of the Frenchmen towards the goal. But he's too far away. Dupont picks it up easily and throws it to Paton.

France and England still have one goal each, and there are only two minutes left. At this moment, anything can happen. Paton kicks the ballacross to Crozat. It‘s a beautiful kick.

Maybe your maths teacher has already taught you how to find the centre of a circle(圆). It isn’t easy to learn and it takes some time to do so. Here’s a simple method(方法). This method can be easily learned in a few minutes.

Put a corner of a square(正方形的) piece of paper on the circumference (圆周) of a given circle, and you’ll see the two sides of the piece of paper meet the circle. And then you’ll get two points on the circumference. You may name them Point A and Point B. You may be sure that points A and B are the two ends of the diameter(直径). Draw a straight line through the two points A and B. Then do the same thing a second time in a different place to get another diameter. You'll find the certre at once:the two lines cross at a point and this point is just the centre of the circle. How about trying to see if it is easy to learn and remember this simple method of finding the centre of a circle?

1.What should be put on the circumference of a given circle if you use the above method to find its centre? ____.

A.The corner of a square piece of paper. B.The two sides of a square piece of paper. C.The four corners of a square piece of paper. D.Two square pieces of paper.

2.Straight Line AB is sure to run___________.

A.through the corner of the piece of paper B.through the centre of the circle

C.along the corner of the piece of paper D.along one of the sides of the piece of paper 3.After you've done the same thing a second time in another place, you'll get another__.

A.circumference B.corner of the piece of paper C.circle D.diameter of the circle 4.Which of the following is the right order to find the centre of a given circle? ____. a.Bring a square piece of paper.

b.Draw a straight line through the two points A and B.

c.Let the paper meet the circle, and then write down the two points A and B. d.Do the same thing again in a different place. e.The two diameters cross each other at a point.

f.Put the corner of the square piece of paper on the circumference of the circle. A.a;b;c;e;d;f B.e;a;b;c;f;d C.a;b;f;d;c;e D.a;f;c;b;d;e 5.When you use this method to find the centre of a given circle, you need ___. A.a pencil, a square piece of paper and a pair of compasses(圆规) B.a pair of compasses, a ruler and a square piece of paper

C.a ruler, a pencil and a square piece of paper D.nothing but a square piece of paper
