AJudy Wright and her husband decided to move closer to their son, Chris, who lived in Georgia. About a month after the move, Judy fell ill, suffering from her ongoing battle against Parkinson’s disease.Her condition worsened rapidly and she required medical care at home. The family hired a nursing aid who cancelled at the last minute. Instead, a woman named TunDe Hector showed up in her place.One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger had helped her with a kind gesture. She had run out of gas, and with only$5 in her pocket, was walking to a gas station, gas can in hand. A man saw her walking and turned his car around. He paid for her gas and gave her all the cash left in his wallet. Upon hearing the story, Judy’s son, Chris, took off his hat and said, “That was me!” He was the stranger that had helped TunDe on that difficult day.During the care of Judy, the Wright family learned about TunDe’s family and her own dream. The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse. Her tuition was past due(逾期)and she had a family to care for, but she was determined to achieve that goal for herself and her family.Judy died on July 9,2017. Instead of flowers, her family asked mourners(悼念者) to donate to TunDe’s education, to assist her in paying for her nursing school. In less than a week, they raised more than $8,000 and presented her with the surprise check.1.How might Chris feel when hearing TunDe’s story?A.Shocked.B. Thrilled.C. Puzzled.D.

Constant dropping wears the stone.BOrganic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious and safer product, then you’d better save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.For their new study, Smith-Spangler and her colleagues conducted a review of two categories(种类) of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analysed the nutritional content of the foods, including key vitamins, minerals and fats. While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The US Department of Agriculture (USDA) states that, “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.4.What does the underlined sentence in the first paragraph mean?anic food helps you save money.anic food is not always nutritious.anic food contains much more nutrients.anic food is worth the high price.5.How did Smith-Spangler and her colleagues carry out the research?A.They made 223 studies about the consumers.B.They made 17 studies about the nutrients.C.They made two kinds of research.D.They compared the consumers with the nutrients.6.What might be the author’s attitude towards organic food?A.It makes little difference to have organic food.B.It costs less money if we all buy organic food.C.Only the freshest organic food is worth twice the price.D.We should not spend any money on organic food.C“One of the reasons I find this topic very interesting is that my mum was a smoker when I was younger,” says Lindson-Hawley, who studies tobacco and health at the University of Oxford.By studying about 700 adult smokers, she found out that her mum quit the right way—by stopping abruptly and completely.In her study, participants were randomly(随机地) assigned to two groups. One had to quit abruptly on a given day, going from about a pack a day to zero. The other cut down gradually over the course of two weeks. People in both groups used the nicotine replacement, like gum or spray. They also had the talk therapy(疗法) with a nurse before and after the quit day.Six months later, more people who had quit abruptly had stuck with it—more than one-fifth of them, compared to about one-seventh in the other group. Although these numbers appear low, it is much higher than if people try without support.And the quit rates were particularly convincing given that before the study started, most of the people had said they’d rather cut down gradually before quitting. “If you’re training for a marathon, you wouldn’t expect to turn up and just be able to run it. And I think people see that for smoking as well. Th ey think, ‘Well, if I gradually reduce, it’s like practice,’” says Lindson-Hawley. But that wasn’t the case. Instead of giving people practice, the gradual reduction likely gave them addiction and withdrawal symptoms(脱瘾症状) before they even reached the day, which could be why fewer people in that group actually made it to that point. “Regardless of your stated preference, if you’re ready to quit, quitting abruptly is more effective,” says Dr Gabriela Ferreira. “When you can quote a specific number like a fifth of the patients were able to quit, that’s acceptable. It gives them the encouragement, I think, to really go for it,” Ferreira says.People rarely manage to quit the first time they try. But at least, she says, they can maximize the odds of success.7.What does Lindson-Hawley say about her mother?A. She quit smoking with her daughter’s help.B. She was also a researcher of tobacco and health.C. She studied the smoking patterns of adult smokers.D. She succeeded in quitting smoking abruptly.8.What kind of support did smokers receive to quit smoking in Lindson-Hawley’s study?A. They were given physical training.B. They were offered the nicotine replacement.C. They were encouraged by psychologists.D. They were looked after by physicians.9.How does Dr Gabriela Ferreira view the result of Lindson-Hawley’s experiment?A. It is encouraging.B. It is unexpected.C. It is impractical.D. It is misleading.10.Take the idea of “a marathon” (Para.5) as an example to show that quitting smoking .A. is something few can accomplishB. requires a lot of patienceC. needs some practice firstD. is a challenge at the beginning第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
