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 onwards 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."

Many of us don't pay much attention(关注)to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.

There are several causes leading to poor eyesight like not enough food, genes(基因) and aging(变老). Televisions, computers and reading are also the causes of having poor eyesight. If you work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, you’d better clean your eyes with cold water. You must also try your best to protect your eyes from harmful things.

Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins.

Cities are taking interest in electric scooter-share systems as an affordable transportation to cut down on pollution and traffic jams. The electric scooters, which weigh between 30 and 40 pounds, reach speeds of about 15 mph.

In September 2017,Santa Monica, California, became the first U.S. city to

have an electric scooter-share service. Users find and unlock one of the more than

1,000 scooters with a smartphone app. A ride costs $ 1,and then 0.15 cents for

each minute of riding throughout the beach town.

Bird, the startup operating the scooter-share, picks up the scooters every

night to them, and places them around Santa Monica each morning ready for people’s use. The company was created by Travis VanderZanden, who once worked in Uber and Lyft, after he realized ridesharing services failed to help with traffic jams and air pollution. Since its September 2017 beginning, Bird’s system has served more than 50,000 riders who have taken 250,000 trips — more than half of which have been in the last month. It’s since expanded (扩 张) to Venice, California, and some neighborhoods in Los Angeles and San Diego. Bird plans to expand to lots of markets by the end of 2018.

Competitors, backed by millionaires, are appearing. Two bike-share startups LimeBike and Spin, have spoken of plans to provide electric scooters in cities this year.

Electric scooters have also gotten the attention of Mayor Pete Buttigieg from South Bend,

Indiana. The city is interested in using them as a way to improve public transportation. South Bend was one of the first to use bike-share systems, which allow people to park ridesharing bikes on public land. “We love to be early pioneers,” said Buttigieg. “If we work out the safety problem, we would be open to welcoming the technology.”

“We need to make sure these new transportation systems are lawful and safe for users,”

Constance Farrell,a spokeswoman for the city of Santa Monica told CNN. “We would like to see electric scooters continue to operate in the city. They are in line with our goal of multi-modal living and carbon-light living. ” According to Farrell,there have been eight accidents, including one with a serious head injury, in Santa Monica after the scooters rolled out. Users are required to have a driver’s license (驾 照),shouldn’t ride on sidewalks or have other passengers on board.

Bird has given out free helmets to some riders and tells its users to ride in bike lanes, but some users ride on sidewalks, and most U.S. streets don’t have bike lanes.

“The global community of cities is going to have to work this all out for scooters,”Buttigieg said. “They can move unbelievably quickly. That’s exciting,and a little dangerous. ”
