AVinegar（醋）is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists，it may even help the planet’s population survive climate chang e. Researchers from the RIKEN Center for Sustainable Reso urce Science (CSRS) in proved that. They found growing pla nts in vinegar makes them more resistant to droughts. This co uld mean that in the future，worries about climate change affecting the world’s supply of f ood will be much lower.The discovery was made after the researchers studied the Ar abidopsis, a plant known for its ability to survive in dry weathe r. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate（醋酸盐）--- the main component of vinegar.After discovering this, the scientists experimented further by a dding acetate to the soil of other plants before they stopped gi ving them water completely. After leaving the plants for 14 da ys, they found that the ones treated with acetate had survived , while the untreated plants had dried up and died.It’s hoped that this simple method of survival could soon be u sed to help farmers in dry countries keep their crops alive. “In the experiment, we targeted the basic foods of the world—rice, wheat and maize... and proved successful” Jong Myong Kim, co-author of the study, told Popular Science magazine. Kim has already been in touch with people around the world who are interested in trying this simple and cost-effective method out for themselves from farmers to companie s and amateur gardeners. “Now we are trying to cooperate wit h them to make a method to apply this system, and make the process as simple as possible,” he said.

The p romise of increased student academic achievement through t he use of technology hasn’t produced any significant results i n the past 20 years.Researchers at the of conducted a study in 2014 to determin e if the social skills of elementary students were blocked by sc reen time.

This was one more weapon for her to defeat my strange problem — inability to read.In the library, I found my way into the “Children’s Room.” I sat down on the floor and pulled a few books off the shelf at rand om. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only a nimal companion I ever had as a child. He was my secret sha rer, but one morning, he was gone, given away to someone w ho had the space and the money to care for him. I never forgo t my beagle.There on the book’s cover was a beagle which looked identic al to my dog. I ran my fingers over the picture of the dog on th e cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the b ook, I borrowed it from the library for the summer.Under the shade of a bush, I started to read about Amos. I re ad very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued t he final scene of reunion, on and on, until my own lost dog an d I were, in my mind, running together.My mother’s call returned me to the real world. I suddenly real ized something: I had read a book, and I had loved reading th at book. Everyone knew I could not read. But I had read it. Bo oks could be incredibly wonderful and I was going to read the m.I never told my mother about my “miraculous” experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year.

But recent experi ments are proving that autonomous vehicles also have the po tential to improve the quality of life for millions of Americans u nderserved by traditional modes of transportation, such as the elderly and disabled, so long a s lawmakers make smart policies that pave the way for inventi on.A retirement community in , , which has been transformed by a small fleet of driverless taxis, shows the potential of self-driving cars to transform people’s lives. Built by a tech compa ny called Voyage, the modified Ford Fusions are currently limi ted to a two-mile road,but residents are already having the benefits of these autono mous vehicles, which allow them to participate in social activiti es they would otherwise be unable to enjoy simply because th ey could not get to them.When the trial run finally expands to 15 miles of road, these re sidents—whose average age is 76—will also have a convenient and reliable new way to appointments. As these cars continue to serve residents there, it is eas y to understand why is moving to simplify laws for the industr y.In , forward-thinking policies have the potential to unlock other hidden ben efits of autonomous vehicles, especially for those with physica l disabilities. The Michigan Disability Rights Coalition has stro ngly advocated for the development of this technology, saying that it could give people with disabilities greater opportunities in the workforce and enable them to lead more fulfilling, indep endent lives.Many recognize that autonomous vehicles will be the future of transportation, but it is too often overlooked that this future ca nnot arrive fast enough for millions of Americans who are forc ed to depend on others for day-to-day travel. The policymakers should follow the lead of places l ike California and , and pass rules and laws to unlock these hi dden benefits of driverless cars.32．What’s the attitude of most American people to the future of autonomous vehicles?A. uncertainB. doubtfulC. indifferentD. optimistic33．What is the modified Ford Fusion?A. The collection of social activities.B. The name of a retirement community.C. A kind of autonomous vehicle.D.

The concept of autonomous vehicles has been widely reco gnized.B. The weak groups are often overlooked despite technology advances.C. The benefits of driverless cars have been fully unlocked.D.
