1 . It was a city in Hubei Province. On International Children's Day, some orphans (孤儿) from the Wuhan Welfare Institute for Children     1    (take) to the park. An elderly westerner was with them. The children were eager to tell him everything that was going on. They held him by the hand and never hesitated to call     2    Grandpa. This man was Professor William Dorrity, from Florida，USA. In 2003,     3    Professor Dorrity and his wife retired, they came to Wuhan and started to work as volunteers at the Welfare Institute.
The Dorritys have been working hard    4    (improve) the conditions at the Welfare Institute since they came. They often take children on day trips,     5    (bring) along with them all kinds of food for the kids to enjoy. They recently bought audiphones for four orphans     6    hearing problems and small tape recorders for three blind children. They also bought a wheelchair for ten­year­old Tan Jun,     7    suffers from a brain problem. With the     8    (arrive) of spring, the Dorritys took the children for     9    outing. “We love China and we love children,” Dorrity said, “     10    we are happy to do this.”

2 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).
