1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

2 . Jenifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's degree.
Mauer, of Edgar, Wisconsin, grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.
Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jenifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.
Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲)to achieve her goal, giving up many nights with her kids and missing important events to study. ''Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,'' she says. However, her children have learned an important lesson witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family-and that's pretty powerful.

3 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
1. What is the recent study mainly about?| A．Food safety. | B．Movie viewership. |
| C．Consumer demand. | D．Eating behavior. |
| A．Big eaters. | B．Overweight persons. |

| C．How we perceive others. | D．How we feel about the food. |
4 . Some teens are disapproving of compulsory BMI (body mass index) （身体质量指数） checks in PE classes. Do BMI checks at school do more harm than good? Two teens take sides.
Maya Meade, a high school freshman in Ohio, says yes. “I understand that schools want to weigh students because they are concerned about their physical health. That’s not a bad thing! But what about their mental health? For many students, appearance and self-image are huge sources of stress. Forcing teens to be weighed at school will only increase the pressure they feel to fit a certain mold (模子)”, says Maya.
In Maya’s opinion, weight is a personal matter that should stay between a doctor and a patient. She says, “Just imagine someone who struggles with body image being told that his or her BMI is too high as classmates look on! Even if other kids can’t hear, no student wants to feel judged by his or her teacher. That’s not why we go to school.”
Maya thinks if a school wants to have an impact on a student’s physical health, there are better ways to do it, such as providing healthy but filling meals, encouraging physical activity and teaching students about nutrition.
Ben Bagbek, a second-year student in a high school in New York, holds a different opinion. “There is no reason why a school should not be allowed to weigh its students and teach them how to calculate BMI! Obesity (肥胖症) is a huge public health concern in our country. And schools are in a position to help students understand what their weight means to their health -- before they’re at risk of life-threatening conditions.”
“A school’s job is to help students reach their full potential, and your health undoubtedly plays a role in your academic performance. BMI is not a perfect measurement, but it can help you identify the need for healthier eating habits or more physical activity.” says Ben.
The bottom line is: When you feel good, you learn better. As long as the actual number on the scale stays private, it should be viewed as an important part of your health education.
1. What are the two teens debating?| A．Whether students are enjoying PE classes. |
| B．Whether schools are body-shaming students. |

| C．Fierce competition. | D．Positive self-awareness. |
| A．It’s private. | B．It’s important. |
| C．It’s hard to lose. | D．It’s not a big deal. |
| A．Most school students are overweight. |
| B．BMI checks are of little help to students. |
| C．Schools have the right to weigh students. |
| D．It’s not schools’ duty to help students keep fit. |
5 . Mary Anning was an English fossil collector, dealer and paleontologist(古生物学家). Her fossil-hunting helped change the way people thought about the world.
Mary was born into a poor family in England on May 21, 1799. She lived in the seaside town of Lyme Regis, in Dorset. The family had nine children. Only Mary and her brother Joseph grew up. Mary’s father took his children along the beach. They picked up shells and stones to sell to visitors. Mary did not go to school much. Her family was too poor. And schools did not teach children about fossils. Mary could read and write. She taught herself. She learned about rocks and how bodies are made.
In 1811 when Mary and Joseph were fossil hunting, Joseph saw a bone sticking out of the rock. Mary had a hammer to chip away at the rock. Very carefully she uncovered it. She found the first complete fossil of the ichthyosaur(鱼龙).
Since then, Mary became crazy about fossil hunting. She liked to hunt on the beach after a storm. The wind, rain and waves made the rocks crumble It was easy to spot fossils. Most days Mary went fossil hunting with her dog, Tray.
Rich friends helped Mary by selling fossils for her. They sent her money. Scientists wrote letters and came to see her. One good friend was William Buckland, a professor at Oxford University. Mary also opened a shop to sell fossils, stones and shells. She chatted with visitors.
Mary Anning died inl847. How evolution(进化)works was explained by Charles Darwin not long after Mary died. Her fossils had helped scientists understand how things began.

6 . The largest genetic study of mosquitoes has found their ability to resist insecticides(杀虫剂) is evolving rapidly and spreading across Africa, putting millions of people at higher risk of contracting malaria（疟疾）.
British scientists who led the work said mosquitoes’ growing resistance to control tools such as insecticide-treated bed nets and insecticide spraying, which have helped cut malaria cases since 2000, now threatens “to disturb malaria control” in Africa.
“Our study highlights the severe challenges facing public efforts to control mosquitoes and tomanage and limit insecticide resistance,” said Martin Donnelly of the Liverpool School of Tropical Medicine, who worked on the study with a team from Britain’s Wellcome Trust Sanger Institute.
Latest World Health Organization (WHO) data show that 216 million people were infected last year with the malaria parasite（寄生虫）, which is transmitted by blood-sucking Anopheles mosquitoes. The disease killed 445,000 people in 2016, and the majority of them were children in sub-Saharan Africa.
To understand how mosquitoes are evolving, the researchers sequenced the DNA of 765 wild Anopheles mosquitoes taken from 15 locations across eight African countries. Their work, published in the journal Nature on Wednesday, created the largest data resource on natural genetic variation for any species of insect.
Analyzing the data, the scientists found that the Anopheles gamblae mosquitoes（冈比亚疟蚊）were extremely genetically diverse compared with most other animal species. This high genetic diversity enables rapid evolution, they said, and helps to explain how mosquitoes develop insecticide resistance so quickly.
The data also showed the rapid evolution of insecticide resistance appeared to be due to many previously unknown genetic variants（变体）within certain genes. The scientists said these genetic variants for insecticide resistance were not only emerging independently in different parts of Africa, but were also being spread across the continent by mosquito migration.
Michael Chew, an expert at Britain’s Wellcome Trust global health charity which helped fund the research, said the finds underlined the importance of pushing scientific research ahead to control malaria.
Global efforts to control malaria through effective vaccine, insecticides and the best drug combinations require urgent, united action by scientists, drug companies, governments and the WHO.

8 . I didn't know how to say no, and was afraid to tell people what I wanted. Instead, I got myself tangled (纠结的) in a web of obligations, anxiety, and white lies.
The worst thing was that I didn't even realize what I was doing. I thought I knew how to say “no”-but couldn't remember the last time I had. Like a lot of people, I just wanted to be accepted, appreciated, loved-and that the only way to get those things was to put everyone else's needs before my own.
I never seemed to have time for things I really wanted to do. I'd like to learn Spanish, write more fiction, and travel. These aren't huge, unrealistic goals. And yet, my people-pleasing ways dramatically cut into my free time to pursue these desires.
But recently, I decided I'd had enough. As an experiment, I began standing up for myself, even at the risk of alienating (使疏远) myself from everyone and having my entire life come crashing down around me. Several days ago, a good friend asked me to go for coffee at 5 p.m. I was planning to hit the gym and then binge-watch Mad Men for the millionth time. I said, “Sorry, I've got things I want to do tonight.” She said, “That's fine. Maybe another time.” It was all so painfully simple that I wanted to cry.
Saying “no” is so much easier. If someone asks me to do something I have zero interest in, I'm polite but honest. “I'm sorry, I don't think that's really for me.” The words slip out my mouth faster than some other lame excuses.
Learning how to say “no” has added several extra hours to my days, days to my weeks, and what feels like months to my years. I no longer have to back-burner my plans to help friends with their job search, or set aside a weekend to read a book draft by someone I barely know. Saying “no” has set me free.
1. Why was the author afraid of saying “no”?| A．She didn't want to tell lies. | B．She wanted to make more friends. |
| C．She wanted to please every one. | D．She was always willing to help others. |
| A．She alienated many friends. | B．She was kept busy all day long. |
| C．She felt depressed now and then. | D．She had no time for her own hobbies. |
| A．Natural. | B．Painful. | C．Angry. | D．Disappointed. |
| A．Lonely. | B．Relaxed. | C．Confident. | D．Lost. |
9 . If you're out for a run, what difference does it make if you're able to tough it out for another 50 seconds? If you're less than a minute from the top of the hill, that extra time can make the difference between having reached your goal and snatching defeat from the jaws of victory.
How do you get those extra seconds of energy? A research team at the Texes Tech University developed a study to measure what effect listening to music would have on exercise tolerance. The researchers based the study on a stress testing. As part of the testing, they noted any changes in heart rate and blood pressure as participants underwent physically stressful exercise.
The tests were done on treadmills (跑步机), which increased in both speed and incline (坡度) through three stages. In the final stage, the treadmills moved at 10 miles per hour at a 14-percent grade. Most of these tests were designed to last up to 40 minutes. The average gym-goers lasted 30 minutes. For this study, they divided 127 participants into two groups. One listened to upbeat(快节奏) music, while the other group had earbuds in but did not listen to music.
The group that listened to music was able to outlast the non-music group by an average of 50.6 seconds. Again, being able to go an extra minute may seem like a no-brainer ,but “after 30 minutes, you feel like you are running up a mountain, so even being able to go 50 seconds longer means a lot," said the study's lead author, Waseem Shami, MD.
The study has confirmed something runners and gym-goers have suspected for years: Listening to music during workout can be beneficial to your endurance. "Our findings reinforce the idea that upbeat music can help you exercise longer and stick with a daily exercise routine," said Shami. When doctors are recommending exercise, they might suggest listening to music, too."
1. Why did Shami’s team conduct the research?| A．To test the effect of music on health. | B．To know the cause of failure in sports. |
| C．To improve runners' exercise tolerance. | D．To record the body change of participants |
| A．They ran much faster than average runners. | B．They created a new record of indoor sports. |
| C．They could run a little longer with music on. | D．They all enjoyed extreme physical challenge |
| A．A dull activity. | B．A foolish action. |
| C．A demanding task. | D．An easy practice |
| A．Developing a daily exercise routine. | B．Listening to music while working out |
| C．Participating in physical stress testing. | D．Taking exercise as doctors recommend. |
10 . This is what HBO’s Veep has been trying to do—by making US presidential election into a comedy.
Presented for the first time in 2012, Veep follows the daily life of Selina Meyer, the fictional vice-president (or “Veep” for short) of the US. We see that as much as Meyer wants to have an influence, she—despite being the second-in-command of the country—is constantly ignored by the president and kept away from important meetings. Meyer herself isn’t exactly competent: she has to put out political fires every once in a while but usually ends up making things worse.
The show also finds humor in a much darker side of politics: the unreal smiles and wrongdoings of politicians. When a mass shooting happens in the show, for example, instead of feeling shocked, Meyer is actually glad, because she feels it may help draw people’s attention from her. “It feels like peeking (窥视) behind a curtain and seeing the truth of who these politicians really are,” wrote reporter Kathryn VanArendonk.
But Veep is refreshing not just for the way it handles politics, but also because its leading role is a woman politician, especially in a comedy, considering the fact that comedies used to be an all-male kingdom. “There’s more opportunity (机会) for women in comedic roles than 20 or 30 years ago,” Julia Louis-Dreyfus, 58 this year, who plays Meyer, said. “There’s more opportunity for roles that are not just the angry wife or the cute girlfriend.”
In the 7th and final season of Veep, which came out on March 31, 2019, Meyer is finally running for president. No matter where the show—and Meyer—is heading, and whether you appreciate its way to deal with politics, the bottom line here is that Veep is funny.
1. Which of the following best describes Meyer?| A．Hardworking and demanding. | B．Humorous and influential. |
| C．Ambitious but untalented. | D．Educated but lazy. |
| A．49. | B．51. |
| C．53. | D．58. |
| A．They are fit for politics. |
| B．They don’t like comedies. |
| C．They were left out of some fields. |
| D．They seldom used to be successful. |
| A．Meyer runs for president | B．Politics can be funny |
| C．Women like power | D．A comedian realizes her dream |
