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. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight from UV rays.

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. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises often and eats the right kind of food, his eyes will stay in good condition for a long time.

All above are natural ways of eye care that help us keep healthy eyes. In a word, eye care is very important, no matter how old a person is.

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. ”

I work as a volunteer for the poor in Haiti. I decided to take my son Brain there for a week, hoping to educate(教育) him.

Before getting out, I told Brain this trip would be tiring and hard. For the first two days, he said almost nothing. Then on the third day, when we were climbing over high rocky mountains, he turned to me and smiled, “Really hard.”

After that, a five-year-old girl, wearing a too large dress and broken shoes, followed Brain around. Later he said regretfully(遗憾地), “I wish I could speak French.” I was surprised that this was from a boy. He always hated French classes.

One day, I was interviewing(采访) a woman villager for an article. By working hard, she had learned to read and write and became part of the leadership(领导层) of the village. That really touched my heart.

Learning her story, Brain was greatly touched. His eyes were wet and there was love and respect(尊重) on his face. He finally understood the importance of my work. When leaving for home, Brain even offered(提供) to stay in as a volunteer. This trip was very meaningful.
