1 . If you ever find yourself trapped in the wilderness without food, you'll have to figure out how to feed yourself. Many plants in the wild are edible, but many are also poisonous. So it is necessary to learn how to determine whether the plants you find can be eaten safely.

Avoid using this method without careful planning. Some plants can be deadly, and even if you follow these guidelines perfectly, there is always a chance that a plant will make you seriously ill. Prepare yourself for wilderness outings by learning about the local plants, and carry a guidebook to help you identify plants. Even if you are unprepared and cannot find food you know to be safe, remember that, depending on your activity level, the human body can go for days without food, and you’re better off being hungry than being poisoned.

Testing the plant in your mouth is dangerous, so go forward very slowly and carefully. First, hold a small portion of the prepared plant part against your lip for 3 minutes. Do not put the plant in your mouth. If you notice any burning, tingling (刺痛), or other reactions, discontinue testing. Second, place another small portion of the plant part on your tongue. Hold the plant on your tongue without chewing for 15 minutes. Discontinue testing if you notice any reaction. Third, chew the plant and hold it in your mouth for 15 minutes. Chew the plant well, and do not swallow. Discontinue testing if you notice any reaction. Fourth, swallow the small portion of the plant. Wait 8 hours. Do not eat or drink anything during this period except purified water. If you feel sick, immediately throw up what you eat and drink plenty of water. If activated charcoal (活性炭) is available, take that with the water.

2 . By the mid-1920s, Pablo Picasso, one of the most influential artists of the 20th century. had been one of the most celebrated men .In 1957, when Pablo Picasso was in his seventh decade, he joked that x-ray technology might one day reveal a lost work underneath one of his early paintings. Today, that prediction became reality although the technology involved goes far beyond x-rays.

Using hyper-modern tools to peer into one of his Blue Period paintings, researchers have not only shown a hidden piece of art history in astonishing new detail, they have revealed a striking amount of insight into Picasso's creative process and style.

The investigation focused on"La Miséreuse accroupie, "or" Crouching Woman, "painted in 1902 and currently owned by the Art Gallery. The painting, an oil on canvas (画布) piece drawing a crouching (蜷坐的) woman who wears a long coat, shows Picasso’s typical Blue Period colors: grey, green, blue and white. It shows that the innovative modernist was inspired by the lines of an underlying landscape painted by an unknown artist.

The analysis also exposes several changes to the woman described in the painting,many of which Picasso ultimately abandoned. Researchers released their findings on Saturday’s press conference of the American Association for the Advancement of Science in Austin, Texas. “We think now it's a landscape painted by someone enrolled at the fine arts academy in Barcelona, someone in Picasso’s orbit but not in his close circle, ”says Kenneth Brummel, assistant curator of modern art for the Art Gallery of Ontario.

As to why Picasso would have “recycled” another artist’s canvas(油画布), reasons could range from economic necessity, as a young artist still establishing himself, to deep inspiration driven by the lines of the image already laid down there. Picasso often re-used canvases for this reason."

“He didn't shave off the canvas or put a preparatory layer over it,” Brummel says.“ Picasso saw this landscape, found inspiration, and decided he was going to paint it immediately."
