Whether that is good or bad, we can't really say, but for the tow of us, going green is not a fad but a lifestyle. On April22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task. With the idea of going green every single day for a year, Our Green Year started. My life and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps. Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic stores. We consume less meat, choosing green food. We have greatly reduced our buying we don't need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished. Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet. Question: It was difficult for the couple to live a green life for the whole year because _ . - they were expected to follow the green fad - they didn't know how to educate other people - they were unwilling to reduce their energy - they needed to perform unusual green tasks
they needed to perform unusual green tasks

Read the following article and select the best answer. Article: Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip. But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service. Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, "In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off." Question: We can infer from this passage that _ . - tipping is no longer a good way to satisfy some customers themselves - tipping is especially popular in New York - tipping in America can make service better now - tipping has something to do with people's character
tipping has something to do with people's character

Read the following article and select the best answer. Article: When I was 10 years old, I tried out for the cheerleading squad. I had taken gymnastics classes for two years to prepare for these tryouts. However, I didn't make the team. It was a heavy blow to me. I cried all night. Kids today won't experience that kind of rejection. They're growing up in "everybody gets a turn" world where every child gets a chance to kick the ball, sing the song, and win the award. But that's not always such a good thing. Parents have become fearful of letting kids fail, thinking that our children are easily hurt and will never recover from anything--that's a serious problem. Last week, my 7-year-old daughter didn't get into the school play. At first, I was upset by it. How would she react? When I gave her the news, I was ready to hug her and cry with her. She looked at me, made a slight face and said, "That's too bad. What's for dinner?" It clearly wasn't the end of her world. Maybe if we let our kids experience rejection once in a while, we'd realize they are much stronger than we think. Kids need to be able to handle disappointments; doing so helps them to prepare for real life. Most importantly, rejection carries the possibility not only for growth and can also motivate kids to try harder the next time. Rejection is pain. There is no way around that. How will our kids ever discover their true talents if we don't let them? Instead of complaining, maybe we should consider rejection an opportunity.
