(配点 23) Everyone wants to do well on tests. Here is some advice from successful students on how to do well on tests. Listen to the teacher from the first day of class for hints about what is important. For example, the teacher will emphasize the important information by repeating it or telling you it is important. When you look over your textbook and notes again, you should already know what is important. After each lecture, look over your notes again. Come to class ready to ask questions about what you don't understand. C Look at the visual aids the teacher uses. For example, if the teacher asks you to look at a diagram or graph in your textbook, make sure you understand why that diagram or graph is important. There may be a question on the test that asks about that diagram. Study for an essay exam. Students who prepare for essay exams do better on all types of exams. Students need to know more information for essay exams than for true/false or short-answer exams. There are no hints on the exam itself, so students must learn more for essay exams. To prepare for an essay exam, always read the *material twice before you start taking notes. When you read the material the first time, it may seem difficult. When you read the material the second time, it will seem easier. This is similar to when you (1) have to find the way to a friend's house for the first time. The second time you go to your friend's house, it's easier because you know the way. It may even seem shorter because you don't have to slow down as much to check street names or landmarks. The same is true with the material you read. The second time you will already know the words and ideas. In China, they lp to stop de After you've read the material twice, take notes. At this point, you'll find that you know some of the material and can focus on what is most important. Don't ignore *footnotes in your reading. Sometimes teachers think the information in a footnote is important and will ask a question about it. Write down the important information in is in the years t your notes. After you take notes, go back and add your opinions to them. Write down For food in the desert. the ideas that you agree with and the ideas that you disagree with.

Phil Hello. This is 6 Minute English from BBC Learning English. I'm Phil. Beth And I'm Beth. Are you a big reader, Phil? Phil Sure, I enjoy reading - and it's also a great way to pass the time on my daily commute to work. But reading isn't just a nice thing to do - it's an essential skill, something you need for everyday activities, whether that's finding out the news by reading a newspaper or buying groceries by reading the labels. Beth And that's why I was shocked by a recent UN report estimating that around the world over 700 million adults are illiterate, which means they can't read or write. Phil Wow! That's a huge number of people excluded from doing basic day-to-day things. So, what can be done to get more adults reading and writing? In this programme, we'll be hearing about projects in two very different countries trying to do just that. And, as usual, we'll be learning some useful new vocabulary as well. Beth But first I have a question for you, Phil. I mentioned a recent UN report on the high numbers of people unable to read and write, but illiteracy is not a new problem. Since 1967, the UN has been highlighting the importance of literacy, being able to read and write, with a day of celebration called International Literacy Day. But when does it take place? Is it: a) the 8th of March? b) the 8th of June? or, c) the 8th of September? Phil I think International Literacy Day is on the 8th of September. Beth OK, Phil, we'll find out if that's correct at the end of the programme. The biggest reason people grow up illiterate is not going to school, and that's especially true for people living in the coastal towns of Bangladesh. Because these towns flood regularly, families are always on the move, making it hard for children to get an education. Phil The Friendship Project teaches reading and writing to groups of Bangladeshi women and girls. They also teach numeracy which means the ability to do basic maths like counting and adding up. Here one student, Rashida, explains the impact it's had on her to BBC World Service programme, People Fixing The World: Rashida My parents never sent me to school and I've suffered from not being able to read and write. My children were embarrassed that I was illiterate. I couldn't even do basic accounting. Until now, I've had to use my fingerprint as a signature as I was illiterate, but now I can sign my name because I can read and write thealphabet, and I'll also be able to keep an account of my expenses. No one can cheat me anymore. Beth Before the Friendship Project, Rashida couldn't write her signature – her name written in her own handwriting. Instead, she had to use her fingerprint. Now, Rashida has learned the alphabet and also some basic maths, so she knows how much money she's spent, and how much she has left. This means no-one can cheat her, can trick or swindle her into taking her money.
