Techniques to Help Us Remember Better
We all have problems remembering things, but there are some techniques that you can use to help you remember.
First of all, remember the names and jobs of the people and where they come from. ______【46】. And you should try to think of funny images as they are easier to remember. For example, we have Tom—the student from Australia. Well, for Tom you might imagine a tomato. Then Australia has a shape a bit like a dog. ______【47】. So imagine Tom's face as a tomato and he's with a dog and the dog is reading a book. So now we have a picture of Tom the student from Australia.
Now let's take the numbers. The best thing to do here is to break a large number up into smaller numbers and then think of things that the numbers remind you of, such as a birthday, a particular year, the number of a house. ______【48】.
With the directions, the best thing is to imagine you yourself following the directions.
______【49】. Count the turnings 1, 2. . . Then turn left. Now imagine going past a supermarket and a cinema and so on.
When you have to remember lists of words, try to build them into a story. So with our words we might start with, "The sun was shining, so I went for a walk. I saw a horse wearing trousers. It was kicking some bananas over a television. The bananas landed in a bag. " And so on. ______【50】. Try some of these techniques and you'll be amazed at what you can remember.
A. We cannot remember the same as we can do before we get old
B. Now let's imagine it's a very clever dog and is studying
C. Create a picture in your mind of yourself going down the street
D. Here, the best thing is to imagine images of the people and the names that you want to remember
E. Again the funnier the story, the better
F. Or with a number like 747 you might think of a jumbo jet—a Boeing 747

听力原文： There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today -- the wheel. This is used in cars, trucks, and tractors, etc., and has made it easier to carry heavy things and travel long distances.
For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800's the world started to change. There was little unknown land left in the world. People did not have to explore much anymore. They began to work instead to make life better.
In the second half of the 19th century, many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big pan of our life today.
The first part of the 20th century saw mom great inventions: the helicopter in 1909, movies with sound in 1926, the computer in 1928, and the jet plane in 1930. This was also a time when a new kind of material was first made. Nylon came out in 1935. It changed the kind of clothes people wear.
The middle part of the 20th century brought new ways to help people get over diseases, They worked very well. They made people healthier and let them live longer. By the 1960's most people could expect to live to be at least 60.

Engineer E. Fred Schubert is talking about a new era of "smart" light sources. "We are looking at lighting systems that provide more than lighting," he says.
He's talking about light-emitting diodes(二极管),or LEDs. Most people know them as being quite small, like the lights that form. numbers on digital clocks. But recent technological advances have made them much more powerful, able to illuminate swimming pools and serve as traffic signals, for example.
Meanwhile, the lighting in offices and schools could be improved to help people stay healthy and productive, by acting on their internal body clocks. The 24-hour internal body clock is best known for governing cycles of alertness and sleep, and for producing jet lag(飞行时差) when people travel across time zones. Lights cues, especially blue light, help keep the clock on its daily cycle. We're pretty much blue-sky detectors. Our clocks count on bright days and dark nights.
But that's not necessarily what modern life delivers. During the winter in the northeast of America, for example, a person can commute roundtrip in the dark and sit all day in electric light that's fine for vision, but may be too dim to stimulate the body clock. That's called biological darkness.
How that affects people has been hard to document in the general population, but studies suggest such possibilities as seasonal depression, fatigue, sleep disturbances and maybe even cancer, especially breast cancer. Some studies suggest reduced productivity on the job. To counter that, architects and lighting engineers might someday take body clocks into account when they design lighting schemes. They may be encouraged to take steps like providing plenty of natural Night through windows and skylights, and installing bright blue LEDs near computer screens to give a dose of clock-adjusting light.
In the following places, where can we not find the LEDs？
A．Digital clock.
B．Traffic lights.
C．Swimming pools.
D．Cassette players' speakers.
M: The trip, yes, but not the preparation.
W: What do you need to do except pack？
M: You know how you always feel so awful whenever you make a big change in time zones？ This time I'm trying an anti-jet-lag program so I'll be alert even for the first day's lectures.
W: But how can you avoid jet lag？ With that late flight and a six-hour difference in time, it's bound to take you a couple of days to adjust.
M: Well this program's supposed to get your body to feel like it's in the new time zone before you leave. The theory is that the food you eat actually tells your body when to be active and when to be restful, so changing your diet can help you be ready' for the time change. You have to alternate feasting and fasting ... you know sometimes eat a lot, sometimes just a little.
W: OK. Now I see why you're not enjoying the preparation. I can't quite picture you fasting!
M: Actually the worst is already over. Two days before the flight, you're supposed to have only light meals and limit yourself to eight hundred calories.
W: That must have been tough.
M: Yeah, but I'm making up for it today. Feast day is much better ... though I still don't get to eat any snacks after dinner.
