1 . Grizzly bears, which may grow to about 2.5 m long and weigh over 400 kg, occupy a conflicted corner of the American psyche — we revere (敬畏) them even as they give us frightening dreams. Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same: a grizzly bear.

“Grizzly bears are re-occupying large areas of their former range,” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven’t been seen in a century or more, they’re increasingly being sighted by humans.

The western half of the US was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act.

Today, there are about 2,000 or more grizzly bears in the US. Their recovery has been so successful that the US Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed.

Obviously, if precautions (预防) aren’t taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits,” says James Jonkel, longtime biologist who manages bears in and around Missoula.

2 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.     1     But no matter when you travel, it’s a good idea to make your reservations at least 90 days in advance.

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.     2     Then you won’t have to walk through several cars on a moving train three times a day for your meals.

Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.     3     In the summer in particular, the air conditioning can make them quite cold.

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.     4     Note: The times listed on the schedules are departure times, not arrival times.

Have fun.     5     Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you’re going 67.92 mph.

A．Train trips aren’t for impatient types.

B．You’ll have views from both sides of the train.

C．The temperature on rail cars is often hard to control.

D．That’s particularly true during busy summer months.

E．You might have to wait longer than 24 hours to catch the next one.

F．Chances are the cost will be a lot less than the cost of one bedroom.

G．He may also book you in a sleeping car that’s right next to the diner.

Mike Shepherd(2011) Skiddaw in Winter Cumbria, England

It was an extremely cold winter’s evening and freezing fog hung in the air. I climbed to the top of a small rise and realised that the mist was little more than a few feet deep, and though it was only a short climb, I found myself completely above it and looking at a wonderfully clear view of Skiddaw with the sun setting in the west. I used classical techniques, translated from my college days spent in the darkroom into Photoshop, to achieve the black—and—white image(图像).

Timothy Smith(2014) Macclesfield Forest Cheshire, England

I was back in my home town of Macclesfield to take some winter images. Walking up a path through the forest towards Shutlingsloe. a local high point, I came across a small clearing and immediately noticed the dead yellow grasses set against the fresh snow. The small pine added to the interest and I placed it centrally to take the view from the foreground right through into the forest.
