The Internet nowadays opens a wide world to people, including teenagers, but many parents worry that their children may meet with something unhealthy when searching online. In order to solve this problem, a new search engine for children called Kiddle has appeared.

    Search results are filtered（过滤）,so only safe website are shown and descriptions are written in simple language. Searches with bad words are shut off, too.

    Kiddles uses the same colors as Google in its logo and a similar design on its homepage, too—with an extra robot picture.

    The top three Kiddle search results show safe websites and pages written specially for kids, and those websites and pages are well chosen and checked by Kiddle developers.

    The fourth to seventh results will be safe and trusted websites that are not written specially for kids, but have content written in a simple way. These results are also chosen and checked.

    Results on the eighth and owwards pages are safe and famous websites that are written for adults. They provide expert content, but are harder for kids to understand.

    Unlike on Google, most results appear along with large thumbnail pictures（缩略图）to make it easier for children to find what they are looking for. For example, when searching for "meow meow". Google produces pages for information about a drug（毒品）that has "meow meow" as its nickname（绰号）,but Kiddle lists information only about cats, even with some cartoon pictures.

    The company explained, "Websites which appear in Kiddle search results satisfy family-friendly requirements, as we filter websites with unhealthy content."

    Jason Weiner is a cook in New York For the past four years, he has offered a "Meatless Monday" menu at his restaurant. The idea is to encourage people to eat more vegetables. To do this, he relies heavily on a vegetable everyone is familiar with: cauliflower.

    Over the years, his cauliflower dishes have enjoyed huge popularity.

    Weiner, in fact, isn't the only cook experimenting with the vegetable. Cauliflower used to be boring. It was something to buy only when there was nothing else on the shelf. Now, however, it's "taking on a starring role," says food writer Elena North-Kelly. Across the United States, sales of cauliflower have grown rapidly for two years. On the Internet, DIY cauliflower recipes(烹饪法) have been viewed thousands of times each.

    Cauliflower can be cooked in many different ways. It can be roasted-like a steak. It can be sliced into a sandwich along with other vegetables. The hottest recipe is cauliflower "rice.” The dish is made by mixing the flower part of cauliflower and then lightly cooking the pieces in oil. The "rice" is rich in vitamins C, K and B6, and very low in calories(卡路里). No doubt it has become very popular.

    Unlike other healthy foods, cauliflower is almost always in season. That's because it can be grown everywhere, throughout the year. The vegetable also sells at a low price.
