Do you drink water that's been left sitting out overnight or even for another day? Have you noticed it tastes different? Tap water that has been left to sit out slowly begins to acquire an off taste. Many people think that this is because of microorganisms . But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it's most likely safe to drink. However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom. As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called bisphenol-A, or BPA, along with other things used to make plastic can leach into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer. Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead. What should we do with plastic water bottles that have been left out in the sun or in the car? A) Throw them away. B) Refill them with fresh water. C) Use them after they cool down. D) Clean them and use them again.

Q: I have been in Limoges for a month now. since living here, I have tried to integrate into the local community and one way I have found to do this is by following the local rugby team. I decided to look for information on the local rugby team after the tourism office could not help me. I searched for the club office online and decided to look into _ . The following day I went back to the club after speaking with them and decided to get a season ticket for the rest of my stay here. I will now be going to each home game as well as travelling to the away games with the team and the fans. I am sure that it is going to be a great experience during my time abroad here. I will also be travelling through various regions of France so I will be visiting new places throughout the season. There is another team in a town called Brive not so far away who play in the top league in France, but I decided to stay local. I may go and see them with other assistants if possible during our stay. I witnessed a friendly match on Saturday when they played Stade Dijon in the division below them. The match finished 70-12. After the match, both teams went to the club house to see the Rugby World Cup semi-final between New Zealand and Australia. Both teams respected each others which is something you don't always see in other sports. I spoke to the president of the club after the game and he told me, "This is a family club." Hopefully this year will be a good year for Limoges. How did the writer try to combine into Limoges' community? A) By taking part in the local rugby team. B) By watching the rugby matches in Limoges, C) By playing often with the people in Limoges. D) By paying close attention to the local rugby team.

*Question*
Today almost everyone knows computers and the Internet. If I ask you "What is the most important in your life ?" maybe you will say "Computers and the Internet." The first computer was made in 1946. It was very big but it worked slowly . Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, "people can't live without computers today." The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends. Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don't know their real names, ages, and even sex . They are so interested in making the "unreal friends" that they can't put their hearts into study. Many of them can't catch up with others on many subjects because of that. We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet. The Internet can not be used for _ . A) studying B) shopping C) thinking D) playing
