Pocket Tape-Recorders “Family and Home Magazine” test what's on the market now.

1）Pearlcorder S702 $64

    This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn't turn off automatically.

Tape length: 30 minutes per side. Weight:240g.

2）Sony M9 $49.95

    Small and very good looking, sony's latest offering scored most for appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. Doesn't switch off automatically but a red light shows if the machine is still running.

   Tape length: 60 minutes per side. Weight: 195g.

3）Sony M400 $115

    Lots of little control buttons that make a noise and are difficult to use . Recording was good but machine noise lost points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful Tape length: 60 minutes per side. Weight: 230g.

4）Imperial OEM. MC $29.95

    Cheap and simple compared with the rest, but recording was good as long as there was no background noise. Use only its own make of cassette. No light to show it is on; no fast forward button and the record button makes a loud noise.

    Tape length: 30 minutes per side. Weight: 285g.

5）Philips 585 $80

    Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light. Tape length: 15 minutes per side. Weight: 220g.

    Everyone wants to win, and everybody knows it. Take the case of Olympic athletes, who train hard each day for years to reach the top of their sport and hopefully win a gold medal. Since every competitor's goal is to win, we assume that the silver medalists would be less happy than gold-medal winners, but still happier than those in third place. Common sense says that our levels of happiness should have something to do with our levels of achievement – except that often this isn't the case.

    Researchers found that bronze medalists actually appeared on the whole to be happier than silver medalists. How could that be? The answer, in a word, is gratitude. Silver medallists, who compared themselves to the gold medalists, experienced disappointment at having been close to winning the gold, but falling short. The bronze medalists, on the other hand, were thankful to have won a medal at all, comparing themselves to all those who didn't even reach the Olympic platform.

    If happiness, then, is the aim of life, perhaps our achievement-centered culture is getting it all backwards. We focus on what we want rather than on what we have. We forget to be grateful, and as a result we forget to be happy.

    We're from a culture that teaches us to envy others – another person achievements – and that is always looking forward to what comes next. Yet in a better society, might we not look at what all of our earlier nexts have already earned us?

    I encourage any person who struggles with frustration （挫折）in their life to take out a notebook and a pen each evening before bed, and to write down all the things that they have gratitude for. It's not a cure for dissatisfaction, to be sure, but many people quickly discover that, when they actually stop to think about it, they have things pretty good and happiness comes.

    Those bronze medalists, after all, can't be wrong.

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were on holiday." I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holidays" is said "vacaciones". So they did not go to the house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to the houses where the sign said "NO VACANCIES", because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means "fun". In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, Thank you".

    Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

    "To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU. ''The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries."

    Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro systems (MNEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.

    "People hear the word 'nuclear' and think of something very dangerous." he said. "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems."

    His new idea is not only in the battery's size, but also in its semiconductor (半导体). Kwon's battery uses a liquid semi conduct or rather than a solid semiconductor.

    "The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure (晶体结构) of the solid semiconductor." Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem."

    Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

Six months ago,Jack came to China to study.He has heard that Yangzhou is famous for its gardens.And he plans to visit some gardens in July,so he has collected information about them online as follows:

In life, there are many opposite things, which cannot be united by many people. But there is always a chance to unite two different things in one work. The following passage will tell you more about the possibility of combining painting and poetry.

Perhaps, it is not a new idea that a great work can be created by combining paintings and poems. In this case, we can unite both things in two ways. The first way is to make the poem as the main inspiration for the painting. It is also possible to write a poem after looking at a painting.

What about the next idea to combine painting and poetry? Well, we can combine both of them on a canvas(画布). You can paint an oil painting on it and then write down the poem on that canvas. I do not know whether this kind of idea has been used for years. But this is quite a great new idea for me. It will make more people love painting and poetry at the same time. You will not need to read the poem on plain white paper any more.

A poem is a good way to represent a story or a thought. It is usually not too long and not easy to understand literally(字面上地). It is a series of words arranged in stanzas(诗节) and lines with rhymes, which are quite changeable. Therefore, combining it with another type of art (such as painting) will be very good. You can get the message of the poem through the colours on the canvas. All you need to do is use your creativity to make a painting with the right colours and with great words on it.
