That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theater. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.

    As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away any possible robbers. Very few people were still out except a few sad-looking homeless people under blankets.

    About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.

    Suddenly I wasn't cold or tired anymore. I ran out of the door and back to where I'd heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.

    Just as I was about to give up the search, I heard the garbage truck pull up to the sidewalk next to me. When a voice called from the inside, "Alisa Camacho?" I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes. "Is this what you're looking for?" he asked, holding up a small square shape.

    It was nearly 3 a. m. by the time I got into bed. I wouldn't get much sleep that night, but I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other.

    Feelings often run high where insects are concerned, with many people even sick when seeing them, let alone touch or swallow them. And yet insects present a huge nutritional opportunity as an increasing global population seeks more sources of food and feed.

    Insects have generally high levels of animal protein and key micronutrients with lower environmental footprints than traditional alternatives, and they can be raised on leftovers. But cultural, social and economic problems remain, reports an article published today in Nutrition Bulletin.

    “Insects present a nutritional opportunity, but it is unclear how their nutritional quality is influenced by what they are fed, "says Darja Dobermann, a researcher at the University of Nottingham.“In ideal conditions, insects have a smaller environmental impact than most traditional western forms of animal protein; less known is how to raise insect production while maintaining these environmental benefits.”

    “Studies overall show that insects could make valuable economic and nutritional contributions to the food or feed sys tems, but there are no clear regulations in place to bring insects into such supply systems without them turning into a more expensive version of poultry（家禽）for food,” says Dobermann.

    The article highlights how insects have been a source of food for hundreds of years in more than 100countries with over 2,000 species that can be eaten; in central Africa, up to 50% of dietary protein has come from insects, with their market value higher than many alternative sources of animal protein.

    Insects need to be large enough to make the effort of catching them worthwhile and easy to locate, preferably in predictably large quantities. They are consumed at various life stages, as raw, fried, boiled, roasted or ground food.

    Cropping (修剪) an Image With the Snap Shot Program

    Welcome to the world of photo-editing!

    Cropping an image allows you to zero in on (对准，聚焦) just the portion that is important to your project. For example, you may want to insert an image of a covered train in a report but may not want to include the whole train. Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.

    Option 1: Cropping by Placing the Image in a Shape

    Screen Shot 1

    Using one of Snap Shot's standard shapes as a photo-editing tool requires no special abilities to crop an image with a standard shape:

    a. Click Cropping & Orientation from the Effects menu.

    b. Click to select one of the six shapes to frame your image.

    c. Use the mouse pointer to draw a frame around the portion of the image you wish to retain. Re-size the frame by dragging the shape's sizing handles. When you are satisfied with the results, click Cut It.

    d. Snap Shot will automatically return to the project that is open. (You may also copy or cut the cropped image and paste it into another application.)

    Option 2: Freehand Cropping of an Image

    Screen Shot 2

    If you want to trace the shape of an object in order to crop out everything else, freehand cropping is the way to go. To crop an image freehand:

    a. Click Freehand Crop from the Cropping & Orientation option on the Effects menu.

    b. Using the mouse pointer, trace around the shape you want to crop. Be sure to completely enclose the image by ending at the same place you began outlining.

    c. Click Cut It. Snap Shot will automatically return to the project that is open.

    Alabama: Priester's Pecans

    Dessert in the South basically starts and ends with an ooey­gooey pecan (核桃) pie. Especially in Alabama, where the pecan is the official state nut. While there are plenty of farms that pick and package pecans, perhaps the most famous is Priester's, a family­run business that's been supplying Alabama with its favorite nuts for over seven decades.

    Alaska: Salmon jerky

    Forget beef jerky (肉干) ­ in Alaska, it's all about the salmon jerky. Home to five different species of the flavorful fish (king, red, pink, silver, and chum), the northernmost state produces nearly one­third of the wild salmon consumed around the world. Bonus: Salmon is one of the seven healthiest fish you can eat.

    Arizona: Saguaro cactus

    The largest cactus (仙人掌) in the United States, the saguaro cactus is found only in Arizona's Sonoran Desert. Living to be up to 200 years old, the cacti, whose flower is also the state's flower, are generally around 30 feet tall and can grow unlimited arms. Want to see for yourself?

    California: Wine Guide

    It isn't called "Wine Country" for no reason. Northern California, specifically Napa Valley and Sonoma Valley, produce over 60,000 registered wine labels, making vino (酒类产品) the state's most valuable agricultural product. If you're looking for the most popular varietals (优质酿酒葡萄汁), the top two frequently planted grapes are chardonnay and cabernet sauvignon.

    Ancient Chinese folk paintings and many other art styles have been passed down from generation to generation, and are still practised in different parts of China. Here's a look at four unique Chinese folk art forms.

    Chinese Opera (戏剧) is the traditional form of Chinese drama. According to incomplete statistics, in China's various ethnic regions there are about more than 360 kinds of operas. The most famous ones include Peking Opera, Kunqu Opera, Yueju Opera, Yuju Opera, Sichuan Opera, Fujian Opera, Hebei opera, Huangmei Opera arid so on, in total more than 50, among which Peking Opera is the most popular in China.

    Shadow Play (皮影戏) dates back to Western Han Dynasty in Shaanxi more than 1,000 years ago. The moving figures, usually carved out from leather, are operated by folk artists, accompanied by music and singing. It is the world's first dubbed (配音的) motion picture art form, thus considered the "ancestor" of modern film. Today this art form is still popular in northern China.

    Paper-cutting (剪纸) is one of the most popular traditional decorative arts in China with a long history. Paper-cutting can be seen across China and it has even developed into different local genres (流派). They are usually used to decorate gates and windows during festivals.

    The Kite was invented by Chinese people. According to legend the earliest kite in China was a wooden bird by Mo Di in the Eastern Zhou Dynasty. Later his student Lu Ban improved the tech and used bamboo as material to make a kite. Today, various kite-flying activities can be found in different regions of China. Shandong Weifang Kite Festival is held every year and attracts lots of kite lovers and travelers.
