Four people in England, back in 1953, stared at Photo 51. It wasn't much-a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed——the shape of DNA. The discovery brought fame and fortune to scientists James Watson, Francis Crick,and Maurice Wilkins. The fourth, the one who actually made the picture, was left out. Her name was Rosalind Franklin. "She should have been up there," says historian Mary Bowden. “If her photos hadn't been there, the others couldn't have come up with the structure." One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions. At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA'S parts and then putting them together. In the meantime, at King's College in London,Franklin and Wilkins shone X-rays at the molecule. The rays produced patterns reflecting the shape. But Wilkins and Franklin's relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant. But the college actually employed her to take over the DNA project. What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to to go or be put in her place.” “As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers,” says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklin was only two steps away from the solution.” No, Franklin was the solution. “She contributed more than any other player to solving the structure of DNA . She must be considered a co-discoverer,”Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light. 【1】Why did Watson get angry with Franklin? A.Because Franklin kept her results from him. B.Because Franklin took the led in the competition. C.Because Franklin proved some of his finding wrong. D.Because Franklin shared her data with other scientists. 【2】Why is Franklin described as "Dark Lady of DNA"? A.She developed pictures in dark labs. B.Her name was forgotten after her death. C.She discovered the black X——the shape of DNA. D.Her contribution was unknown to the public. 【3】What is the writer's attitude toward Wilkins, Watson and Crick? A.Respectful B.Disapproving C.Admiring D.Doubtful 【4】Which can be the most suitable title for the passage? A.Much pain, no gain. B.Be nice, never finish last. C.When one door closes, another opens. D.Where there is a will, there is a way. |

Currently, vegetarianism is increasingly popular, but it is still not the best option for many. If you may be contemplating removing meat from your diet but do not want to go completely meat-free,perhaps try going meat-free for just one day a week. Sharon Palmer, a registered dietitian and author of Plant Powered for Life, discuses how "research consistently shows that plant based diets are linked with a lower risk of obesity, hypertension,heart disease ,type 2 diabetes and cancer. She says, "Even going meatless one day a week can make a difference, as you increase all of those whole plant-foods beans, wholegrains, nuts, seeds, vegetables,fruits-and decrease more animal foods, in particular red and processed meat. A high intake of these foods has been linked with increased disease risk.” Deciding to have a more plant-based diet also increases your intake of fiber, vitamins healthy fats and minerals. To help to do this，stocking your fridge with a variety of beans seasonable veggies , wholegrains, herbs, nuts and seeds is Palmer's secret to eating more plant-based meals. Palmer's other recommendation is“plantifying”"your favorite dishes. "Just make your favorite dishes or meals plant-based,with a few changes. If you love Taco Tuesday, make your tacos veggie by skipping the meat and serving black beans or a vegetarian mushroom with tofu filling. If you love Indian food, skip the chicken masala and have chickpea masala instead. These will be foods you already love and are familiar with.” Her biggest advice is to pick one day a week to follow through this and mark it on your calendar, "I love the Meatless Monday idea because people often start their best behaviour at the beginning of the week. . .However, there may be a better day of the week for you. So just plan it. " Palmer said. 【1】What does the underlined words “contemplating" in Paragraph l most probably mean? A.Stopping B.Delaying C.Resisting D.Considering. 【2】Why does the writer mention Sharon Palmer as a registered dietitian and author of a book? A.To make us firmly believe Palmer’s advice.

Do you find yourself unable to go more than 15 minutes without reaching into your pocket, pulling out your smart phone and checking your e-mail or WeChat? Don't panic. You are hardly alone. A recent survey shows that smart phone users have developed "checking habit"—frequently checks of e-mails and other Apps. The checks normally lasted less than 30 seconds and were often done every 10minutes. On average, the study subjects check their phones 34 times a day. And the strangest part is that they don't even realize they are doing it. "I hadn't told my hand to reach out for the phone. It seemed to be doing it all on its own," wrote Elizabeth Cohen, a medical correspondent for CNN who watched her right hand sneaking away from her side to grab her phone while sitting on the table at dinner with friends. Loren Frank, a neuroscientist at the University of California, San Francisco (UCSF), explains that checking smart phones is rewarding in some way. "Each time you get an e-mail, it's a little bit exciting, because it means a positive feedback that you're an important person," Frank told CNN. Once the brain becomes used to this positive feedback, reaching out for the phone becomes an automatic action you don't even think about consciously, said Frank. Professor Clifford Nass of Stanford University added that constantly checking your smart phone is also “an attempt to not have to think hard but feel like you are doing something". However, every coin has two sides. This habit can cause problems. Study show that whenever you take a break from what you are doing to check your smart phone, it is hard to go back to your original task, according to Adam Gazzaley, a neurologist at UCSF. That's not the worst. A survey by South Korean marriage consulting agency Duo earlier this year shows that smart phones are destroying intimate relationships, reports The Korea Herald (韩国先驱报). About half or the respondents said they had had fights with their boyfriend or girlfriend because of smart phones. And 32.8 percent of them fought about smart phone obsession. In this respect, checking smart-phones at regular intervals is a bad habit. But just as an old saying goes, "Bad habits die hard.” So to get rid of the checking habit, Cohen suggests establishing phone-free times and zones. 【1】What is the most unusual part of the study subjects? A.The times of phone checks. B.The lasting time of phone checks. C.The unawareness of checking phones. D.The high frequency of checking phones. 【2】What does Loren Frank think of checking smart-phones frequently? A.It is worthwhile in some way. B.It is necessary to think hard. C.It is unimportant for those busy people. D.It is likely to cause neurological diseases. 【3】Which of the following is the worst effect of the “checking habit” has on phone users? A.They might not have a good rest. B.They would be taken in by other people. C.They might get distract from their work. D.They would lost time to keep close relationship. 【4】What is the main purpose of writing this passage? A.To introduce a smart-phone consumption survey. B.To present the obsession with smart-phone checking. C.To list the advantage of smart-phone checking habit. D.To offer the ways to quit smart-phone checking habit. |

Many people become successful because they pay attention to the lessons that life teaches them. 【1】 However, by learning to deal with the challenges, one can come out of the experience, wiser, stronger and more able to face whatever else lies ahead. Life lessons can occur in any area. Although we learn many things each day, we don’t always learn something that we feel will affect our behavior for the rest of our lives.【2】It is usually something we are greatly changed by. For example, if we respond in a certain way to something and then face unpleasant consequences, we’ll rethink how we handled the situation. This can serve as a life lesson so that when we’re faced with similar circumstances, we can consciously change our behavior. 【3】 Such lessons in relationships are as varied and unique as each relationship, yet there are common themes. 【4】 Some of us learn a major life lesson when a loved one dies, and we wish we had spent more time with that person. This lesson can result in us spending more time with our remaining loved ones. 【5】 Since the lesson is learned through the consequences of our actions or reactions, in this way we can gain insight into how we think, act and react in certain situations. Perhaps one of the biggest lessons we can finally learn is that while we can’t control everything, we can control our response to things. A.Life lessons are unique to each person. B.Some of these lessons are learned the hard way. C.This separates a life lesson from everything else we learn. D.Spending more time with loved ones is one of the examples. E.Life lessons can serve to help us understand ourselves better. F.One way to improve your life is to learn something new every day. G.To put it simply, a life lesson teaches us not to make the same mistake twice. |
