    A new study shows that rising levels of planet-warming gases may reduce important nutrients(营养物质)in food crops

Researchers studied the effects of carbon dioxide on rice, In the experiment, scientists grew 18 kinds of rice in fields in China and Japan.They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century.Rice grown under high carbon dioxide conditions had,on average,13 t0 30 percent lower levels of four B vitamins and 10 percent less protein(蛋白质)The crops also had 8 percent less iron and 5 percent less zinc than rice grown under normal conditions However, vitamin E leveLs increased by about 13 percent on average.

The researchers said the effects of planet-warming gases would be most sevcre for the poorest citizens in some of the least developed countries.These people generally eat the most rice and have the least complex diets.That includes abour 600 million people in Indonesia, Cambodia,Myanmar,Bangladesh,Laos and other nations,mainly in Southeast Asia.

Other studies have shown that higher temperatures from climate change and weather extremes will reduce food production.But scientists are finding that rising levcls of carbon dioxide and other planet-warming gases threaten food quality.

Earlier studies showed that wheat,rice,field peas and soybeans grown under high carbon dioxide conditions all had Iower levels of protein and mincrais.Scientists predicted that almost 150 million people might be at risk of having too little protein or zinc in their diet by 2050.

The new study suggests a way to lower the nutritional harm of climate change.That is to grow different forms of rice that can adapt to higher carbon dioxide levels.

1.Growing rice under high carbon dioxide conditions may____.

A.increase iron in the rice

B.make it less nutritious

C.cause losses of Vitamin E

D.make it more delicious

2.How can people reduce the nutritional harm of climate change?

B.By taking other kinds of food instead of rice.

C.By avoiding eating rice from Southeast Asia.

D.By growing rice suitable for the environment.

3.What’s the author’s purpose of writing the text?

A.To infom readers what nurrients food crops contain.

D.To tell readers where food crops are mainly produced.

4.In which part of a magazine can you read the text?

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’ t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company’ s “ Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’ s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “ We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

1.How are social robots different from household robots?

A.They can control their emotions.

B.They are more like humans.

C.They do the normal housework.

D.They respond to users more slowly.

2.What can a Jibo robot do according to Paragraph 3?

A.Communicate with you and perform operations.

B.Answer your questions and make requests.

C.Take your family pictures and deliver milk.

D.Obey your orders and remind you to take pills.

3.We can learn from the last paragraph that social robots will ______.

A.train employees

B.be our workmates

C.improve technologies

D.take the place of workers

4.What does the passage mainly present?

A.A new design idea of household robots.

B.Marketing strategies for social robots.

C.Information on household robots.

D.An introduction to social robots.

    Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown. "There's so much to learn," he'd say. "Though we're born stupid, only the stupid remain that way.” He was determined that none of his children would be denied an education.

Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point. Then came the moment—the time to share the day's new learning. Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen. "Felice," he'd say, "tell me what you learned today.” "I learned that the population of Nepal is ....”  Silence.

Papa was thinking about what was said, as if the salvation of the world would depend upon it. “The population of Nepal. Hmm. Well . . . . ” he’d say. “Get the map; let's see where Nepal is.” And the whole family went on a search for Nepal.

This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.

As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another's education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.

Later during my training as a future teacher, I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.

1.What do we know from the first paragraph?

A.The author's father was born in a worker's family.

B.Those born stupid could not change their life.

C.The town elders wanted to learn about the world.

D.The poor could hardly afford school education.

I will never forget the moment when we returned to school. Because the outbreak of COVID-19, we had to stay home and study from home in depression. I was touching when I stepped into the school, which everything was thoughtfully-arranged. The staff must have worked hard to keep it tidy and safe but we could study in a comfortable environment. There were sign telling us to wash hands frequently and wearing masks. Ms. Chen, our headteacher, greeted us warm in the classroom. A mask was covered most of her face, but her eyes were shining. She said we had done her part to stop the disease spreading. What a unforgettable reunion!
