It is very    {#blank#}1{#/blank#} to deal with the rubbish in cities. This is because rubbish not only pollutes the environment but also does harm to people's   {#blank#}2{#/blank#} . We are trying to find some ways of dealing with the rubbish. First, the rubbish can be divided into different kinds. Newspaper and glass can be  {#blank#}3{#/blank#} . Used tins can be made into beautiful handicrafts（手工艺品）. Polluted water is a big {#blank#}4{#/blank#} . It must be dealt with properly before we let it flow into the river. Some harmful rubbish can be buried（埋）so that it will cause {#blank#}5{#/blank#} pollution.

    A doctor was teaching some medical students at a famous hospital. A patient {#blank#}1{#/blank#}in, and the doctor asked one of his students, "What's wrong with the man?"

   "I don't know, sir," the student answered." I need to examine him."

   "There's no need{#blank#}2{#/blank#} him," said the doctor." You should know without asking questions. He {#blank#}3{#/blank#} his right knee. Didn't you notice the way he walked? He hurt it by burning it in the fire. You see his trousers leg is burnt away at the knee. It {#blank#}4{#/blank#} Monday morning now. Yesterday was fine, but on Saturday the roads were wet and muddy(泥泞的).  The man fell down on Saturday night."

    The doctor then turned to the man," You had your pay on Saturday and went to a public house and {#blank#}5{#/blank#} too much. You got muddy and wet on the way home. Because you had drunk too much, you fell on the fire and burnt your knee. Is that right?

   "Yes, sir," said the man.

It was sunny last Saturday. Mr. Black {#blank#}1{#/blank#} his children to the zoo. When they {#blank#}2{#/blank#} there, they saw many people and animals.

The children went to the lake first. There they saw many fish {#blank#}3{#/blank#} in it. Jane was really happy, "Look, how beautiful the fish are! I hope I can swim {#blank#}4{#/blank#} them." Then they went to the bird garden. There were different {#blank#}5{#/blank#} of birds in it. These birds were not {#blank#}6{#/blank#} when people were near them. Mr. Black bought some bird food for the children {#blank#}7{#/blank#} them. The children were very happy. After {#blank#}8{#/blank#} many hours in the zoo, the children were hungry. Then Mr. Smith took them to a {#blank#}9{#/blank#} for lunch. The food was expensive {#blank#}10{#/blank#} very delicious. All in all, they had a great day.
