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.

    Wetlands are ecosystems found in low, flat areas. Often they border ponds, rivers, lakes, and oceans. Wetlands include marshes, swamps, and bogs.

    No trees grow in a marsh, but there are lots of grassy plants. Ducks, turtles, and many different bugs (虫子) live there, too. Florida has the world's biggest freshwater marsh. The Everglades covers 4,000 square miles. The Everglades is not entirely fresh water, however. Near the sea the fresh water and salt water mix. Some plants and animals can live only in this brackish water.

    Saltwater marshes lie along the East Coast and the Gulf of Mexico. During high tide these marshes are under water. During low tide these marshes can be seen. The water rushes out, carrying bits of plants, dead animals, and minerals necessary for sea animals. Many plants and animals depend upon this ever-changing environment.

    Swamps are forested wetlands. Like marshes, they are often found near rivers or lakes and have mineral soil that drain very slowly. Unlike marshes, they have trees and bushes. Swamps have trees that grow with their roots underwater. But the trees will die if their roots stay underwater too long. Animals such as water snakes and frogs live in swamps.

    Bogs have damp, soft soil. So many dead plants have piled up that there is no longer any standing water. This rotting plant matter turns into peat (泥炭). In Ireland and Scotland peat is dried and burned to heat homes. Bog soil is useful for growing wild rice. Lots of insects live there.

    Most people do not find wetlands beautiful. But wetlands are important. Marshes and swamps store water, thus reducing the flooding a heavy rain can cause. About one-third of all of America's endangered plants and animals live in wetlands. Now laws protect some wetlands. More than a dozen wetlands in the US are refuges (保护区) and wildlife preserves.

    In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

    To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge, Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

    The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

    A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

    Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is "the- number - one problem". Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. "If you shut clown Interstate 90, you shut down interstate trade." she adds.

    Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(预定), which can add up to discounts on restaurant visits.

    Max McCalman's Cheese&Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese&Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese&Wine Pairing app is free.

    HappyCow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

    "Where Chefs Eat" is a 975-pagc book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

Jack Horner is co-author of the book How to Build a Dinosaur. However, he is most famous for his role as consultant(顾问) on all four Jurassic Park films, including the new film Jurassic World.

The original film Jurassic Park tells the story of a theme park where dinosaurs live. In that movie, scientists used DNA collected by ancient mosquitoes that had been trapped in amber shortly after they drank dinosaur blood. The scientists used this dinosaur DNA to create baby dinosaurs. The scientists in Jurassic Park created various types of dinosaurs, but in the real world there is one big problem with the story. It turns out that DNA could not possibly survive the 65 million years since the death of the dinosaurs.

The new movie creates the Indominus Rex. This idea of creating a hybrid species is something Horner has explored before. In 2011, he gave a speech in which he discussed producing a dinosaur by working with the genes of a bird. Modern birds are the closest living relative of dinosaurs.

The concept of using the genes of different animals to create new animals is called transgenic science. And this type of science has already produced some interesting results — goats that produce spider silk in their milk, cows that produce proteins for medicines that can treat diseases, and a pig that produces less-polluting waste thanks to a bit of mouse DNA. However, none of these examples are close to the dinosaurs in Jurassic World. And for a good reason — genetics is a very complex science. Producing a new species is not as simple as just exchanging a few genes around.

In the end, Jurassic World is all about fun.

Perhaps you have seen them, those who fall asleep on the subway and then, somehow, wake up exactly at their stop. Perhaps you are one of them. How is this possible? We spoke to two doctors, who offered their insights about it.

It is possible that your body gets used to waking up at a certain point each time during your commute, said Dr. Marc I. Leavey, a primary-care specialist in Maryland. That holds especially true if you commute at the same time every day. This suggests that if you were to get on at a different time, or if the journey were delayed, your internal clock might not wake you up at your stop. It is an interesting theory, but Dr. Ronald Chervin, director of Michigan Medicine's Sleep Disorders Centers, does not fully buy it. He is skeptical that circadian rhythms can also explain why you wake up after a brief nap.

You are also likely to wake up for your particular stop because of an oral cue, such as the conductor stating the name of the subway stop over the public-address system. Such cues alert your brain that you have arrived, explained Dr Leavey. According to a study published in the Public Library of Science, during sleep, our brain reacts differently when we hear our own name and other people's names, noted Dr Chervin. This suggests that your brain does not turn off during sleep, which makes it possible to pick up on the announcement of your stop.

Another reasonable possibility: You may wake up at each stop, check if it is yours, and go back to sleep, all without having remembered it, added Dr. Chervin. He sees this in cases where patients are suffering from sleep apnea. They may wake up as many as 200 times during a single night, without having remembered a single instance. That's because they fall right back asleep before their brain has time to process their experience into long-term memory. Similarly, you could be waking up every time you hear a new stop called. But you just don't remember such instances even after you fully come awake for your stop—leading you to believe that you have slept the whole way through and miraculously woken up at the right time.
