There are some differences between British English and American English. In grammar, for example, speakers of British English say "in hospital" and "Have you a pen?". Americans say "in the hospital" and "Do you have a pen?". Pronunciation is sometimes different. For example, when a learner speaks British pronunciation[da:ns] (dance), he may not understand the American pronunciation[dæns]. There are differences between British English and American English in spelling. For example, "travelled" and "honour" are British spelling, "traveled" and "honor" are American spelling. However, in most situations(情况), British English and American English are not different languages.

    Goldfish are good pets. They are funny to watch. But they need the right home. They are not happy if they are living in a bowl. A tank is bigger. It can hold more water and it has more room for goldfish to swim. So a tank is a good place for goldfish. Here are some ways for keeping goldfish in a tank.

    Put a tank at home. Do not put it near the window. It could get too warm from the sun.

    Put some water in the tank. Wait a few days, check the water and make sure the water is clean. Then put some rocks and plants on the tank bottom for fish to hide behind them.

    Get your fish. Bring it home in a bag. The bag must be full of water. Let the bag float (漂动) in the tank. Wait half an hour. Then open the bag. Let the fish swim out.

    Look after goldfish. First put a cover on the tank. It can keep fish safe. With a cover nothing can fall into the tank and fish cannot jump out. Do not feed your fish too much! A fish should eat most of its food right away. Clean the tank each week. To keep the water clean, you must take out old water and add new water.

    Your fish will be happy to live in a tank.

    The digital(数字的)age has come into our life. In the USA, some teachers think digital search tools(工具)have had a good influence on the American teenagers, but others don't think so. More than 2,000 high school teachers took s survey on the Internet.

    75 percent of the teachers agreed the Internet and digital search tools have had a "mostly good" use for their students' research habits and skills. But 87 percent thought that these technologies" make the students not have enough attention." And 64 percent said the technologies "do little to help them in courses."

    Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital search tools are helping students learn more, and lean faster. Teachers really like these tools because they are ways to make some of learning very exciting. Young people enjoy using these tools. And the goal is to help them do creative work, and not just that kind of copyist(模仿者，抄写员).

    But one problem is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the information on the Internet is good or bad.

    Another problem is something that might not seem like a problem at all, being able to quickly find information from the Internet. Teachers say the ability of their students to work hard to find out answers is becoming weaker. They say students depend too much on search tools and do not make enough use of printed books.

    Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities.
