A car made from a banana

Have you experienced a car made from a banana or a pineapple? It's not a joke. Scientists in Brazil have developed a new way to use fibers from fruit plants to reinforce car plastics.

By using fibers from seemingly delicate fruits such as bananas and pineapples, the scientists claim that they can strengthen new plastics, making them not only stronger and lighter, but more sustainable (可持续的) as well.

“They (the new plastics) are light, but very strong — 30 percent lighter and three to four times stronger than old plastics，” research leader Alcides Leao from Sao Paulo State University in Brazil told the American Chemical Society. Some of the fibers can be as strong as Kevlar, a super-strong material used to make bulletproof vests. Besides, the plastics are also more resistant to damage from heat, water, oxygen and even spilled gasoline.

Cellulose (纤维素) is the main component (成分) of wood and has been used for centuries to make paper. Recently scientists have discovered that intensive (密集的) processing of wood releases tiny or nano-cellulose fibers, so tiny that 50，000 could fit across the width of a single human hair. When mixed with other raw materials, these nano-cellulose fibers can make plastics stronger.

According to Leao, pineapple leaves and stems (茎), and a plant related to the pineapple in South America, called curaua, rather than wood may be the most promising source for nano-cellulose. To create the plastics, researchers put the leaves and stems of pineapples and other plants into a device similar to a pressure cooker. Then they added certain chemicals and heated the mixture over several cycles, producing

a powder that was then added to the plastics.

The process is costly, but it takes just 1 pound of nano-cellulose to produce 100 pounds of super-strong, light-weight plastics, Leao pointed out.

Some car makers have already tested these nano-cellulose plastics and scientists have predicted the plastics would be in use within two years, mainly for bodies of cars.

1．The underlined word “reinforce” in the first paragraph is closest in meaning to “________”．

A．take the place of B．make something stronger C．increase the percentage of D．get rid of

2．Which of the following statements about the nano-sized fruit fiber is TRUE? A．It is used to make bulletproof vests.

B．It is used to replace steel and aluminum automotive parts. C．It can resist damage from heat, water or oxygen. D．Leao thinks it is better than nano-cellulose from wood.

3．According to the article, which of the following is the correct order that researchers produced super-strong, lightweight plastics?

a．put pineapple leaves and stems into a device similar to a pressure cooker b．a powder is formed

c．add some powders to the plastics

d．add certain chemicals and heat the mixture over several cycles A．b－c－a－d B．a－b－c－d C．b－a－c－d D．a－d－b－c

4．We can conclude from the article that nano-cellulose ________． A．costs too much to produce

B．is the best if produced from wood C．is about the width of a single human hair D．is currently being tested to build bodies of cars

Telemedicine is the name for when doctors give advice to patients by telephone or the Internet, or when health care providers in rural areas connect with specialists in big cities.

Telemedicine has existed for a long time, but the rise of smart phones, tablets and webcam-equipped computers is raising telemedicine to new levels. Some health care systems in the United States now offer Virtual Urgent Care, patients see a doctor by video chat without having to leave home.

Diana Rae is a nurse educator in the western state of Washington. She recently showed how Virtual Urgent Care works. She used an iPad tablet and skype — the video chat service.

Doctor Green has the patient describe her symptoms, then the doctor performs a physical exam by demonstrating what he wants her to do. Doctor Green decides that the problem is a silence infection. For medicine, he prescribes an antibiotic. He says about 3 out of 4 patients have health problems that can be treated like this — through Virtual Urgent Care, that means a video chat could replace a visit to the doctor's office.

The Franciscan Health System is based in Tacoma, Washington. Franciscan charges $35 for this kind of virtual house call, that is much less than the cost of going to an emergency room, a doctor's office or an urgent care clinic.

After trying the video conference, Diana Rae says，“I would've paid twice that for the convenience of getting taken care of without having to sit in a waiting room, wait, and get exposed to everyone else's germs.”

Franciscan has a deal with a company called Carena to add virtual urgent care by Skype or phone. Carena is one of several companies doing this kind of work around the country. But a company official says state rules have not kept progress with
