1 . 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).

2 . New restaurants, galleries, temples and new architecture…These places are homes for people like us who live and work there. How would you want visitors to behave in your own home? Think about it.    1    There are many ways of doing this without sacrificing our own holiday.

Do your homework    2    Guides will help you when you get to site, but is that the best place to go? Is it popular only because the one-day tourist can see it easily or because it is really a worthwhile place to visit? You’d better check it out.

    3    Don’t go to your hotels for meals. Walk around, even if in the streets closest to your hotel. Eat in local restaurants.Talk to the locals. Learn a few in the local language and use them. You will surely get a smile from the hotel staff and street sellers .

Help preserve the sites. Most of the sites you visit may be visited by millions of people a year, so care needs to be taken to allow others to enjoy them as well. Some of these monuments are so old and fragile that they are sensitive to the touch of hands or bags and shows.    4    This way, you don’t encourage the use of those plastic bags that fly all over many sites.

And here’s the big one—good manners are nearly universal.    5    If that doesn’t sound like you, then give the world a break and stay home.
