An old man who lived in a small street in the city of Mumbai had to put up 　1　 　the nuisance(烦心事)of having boys play cricket outside his house at night.

One evening when the boys were 　2　 (particular)noisy,he went out to talk to them.He explained that he was happiest 　3　 　he could see or hear boys playing his favourite game,cricket.He said he would give them 25 rupees(卢比)each week to play in the street at night.

The boys were thrilled.They were being paid to do something they enjoyed! At the end of the first week they 　4　 (knock)at the old man?s door and asked him to pay them,and so he did.

The second week when they asked for 　5　 (pay)he said he had run out of money and sent them away with only 15 rupees.The third week the man said he had not 　6　 　received his pension and gave them only 10 rupees.The boys were very 　7　 (disappoint)but there was not much they could do about 　8　 .The fourth week the man said he could not afford to pay them 25 rupees 　9　 　he had promised,but would give them 5 rupees each week without fail.

This was too much for the boys.“You expect us to play seven days 　10　 　week for a merely 5 rupees!” they yelled.“Go to blazes.” They stormed away and never played on the street again.　

Many years ago,when I worked as a volunteer at Stanford Hospital,I got to know a little girl 　1　 (name)Liz who was suffering from a rare and serious disease.Her only chance of recovery appeared to be a blood transfusion(输血) 　2　 　her 5-year?old brother,　 3　 had miraculously survived the same disease and had developed the antibodies needed to fight the 　4　 　(ill).

The doctor explained the situation to her little brother,and asked the boy if he would be willing to give his blood to his sister.I saw him hesitate for a moment 　5　 taking a deep breath and saying,“Yes,I^,ll do it 6　 it can save Liz.”

　 7　 　the transfusion progressed,he lay in bed next to his sister and smiled,as we all did,　 8　 (see)the color returning to her cheeks.Then 　9　 　face grew pale and his smile faded.He looked up at the doctor and asked with a trembling voice,“Will I start to die right away?”

Being young,the boy had　 10　 (understand)the doctor; he thought he was going to　 give his sister all of his blood.　

White pollution refers to plastic pollution.It is 　1　 　new member of pollution family,　 2　 　it grows fast.Plastic lunch boxes line 　3　 　railroads.Plastic shopping bags dance in the wind.When leaders are busy 　4　 (map)out blueprints for the future,one colour WHITE from white pollution becomes their headache.Everything in the lifecircledeserves its place on earth.If we continue

　 5　 (use)plastic lunch boxes,shopping bags and other plastic products,what would happen？One day they might bury us in an ocean of white rubbish.Then the earth,our common home,may be a dustbin.To prevent this nightmare 　6　 　coming true,governments need to work closely 　7　 　each other and back up their verbal commitment by actions.However,　 8　 　is not enough only to ask 　9　 　governments can do to get rid of white pollution,we must ask 　10　 　what we as individuals can do to colour the earth green instead of white.
