A company in San Francisco, California, has found a way to turn used plastic bottles into women’s shoes.
Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company’s co-founder. He explains how ihey turn plastic into soft material for women’s feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers arc then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe arc then attached to the shoe’s outer part, called the sole (鞋底).This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rolhy’s shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. “We’re not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled material to make other products.
For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

Spring is coming, and it is time for those about to graduate to look for jobs. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing, our family and friends may accept us, but the workplace may not.
A high school newspaper editor said it is unfair for companies to discourage visible tattoos (纹身)，nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do “cover” themselves in order to convey certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.
Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees, because those people represent the companies to their customers.
As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can’t expect all our customers are.
There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.
1.Which of the following is the newspaper editor’s opinion according to Paragraph 2?
A. People’s apperances cany messages about themselves.
