Well, I have to say that for me, even after living in the US for one year and a half, I am still not used to the changes of weather, or how to manage my money well. There are many things that can give us culture shocks, but it is up to us whether to make it a big shock or a small one. I know that changing schools was a big thing for me. It helped me to be stronger and open towards meeting new people. Sometimes it feels like everybody is already in a group. This makes it harder for someone else to go in. But, it is not that hard.

It was raining ice, really, and you could hear sounds outside the window like little pieces of rocks hitting it, of course it was the ice. It started _ so heavily that the University had to close down for two days, and it got worse when it started snowing after the ice storm.

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: An American writer, Mr Green once said, "Everybody talks about the weather, but nobody does anything about it." It is true that everybody talks about the weather. Many people begin their talks by saying, "Isn't it a nice day?" "Do you think it will rain?" "I think it's going to snow." Many people think they can tell what the weather is going to be like. But sometimes they don't agree with each other. One man may say, "Do you see how cloudy it is in the east? It's going to rain tomorrow." Another man will say, "No, it's going to be fine tomorrow." People often look for the weather they want. When a farmer needs water, he looks for something to tell him it's going to rain, and he doesn't look for anything else. When friends have a picnic, they hope the weather is going to be fine and they can sit eating their lunch under the blue sky. Almost everyone listens to what the weatherman says. But he doesn't always tell us what we want, and sometimes he makes a mistake. Still, he is right most of the time. Options: A Almost everyone listens to what the weatherman says.
