New research has found that young adults who smoke both tobacco cigarettes and e-cigarettes appear to have a higher risk of stroke than those who only smoke tobacco.
Carried out by researchers at George Mason University, the new study looked at 161,529 participants aged 18 to 44 years of age, who were surveyed about their cigarette and e-cigarette use.
The researchers also calculated the participants’ risk of experiencing a stroke, taking into account factors such as how much participants smoked, high blood pressure, diabetes, cholesterol levels, body mass index and physical activity levels.
The findings, published in the American Journal of Preventive Medicine, showed that the participants who smoked cigarettes and used e-cigarettes were nearly two times more likely to have a stroke compared to current cigarette — only smokers, and nearly three times more likely than non-smokers.
The team also found that participants who used only e-cigarettes had a lower risk of stroke than those who smoked only tobacco cigarettes. In fact, those who used e-cigarettes on their own did not have a significantly greater risk of stroke than non-smokers.
However, the researchers failed to find any clear benefit from switching from cigarette smoking to using e-cigarettes, even though many people believe that e-cigarettes are a “healthy” alternative to cigarettes, and a way to help smokers kick the habit. They also noted that the nicotine dependence and toxicity associated with e-cigarettes is worrying, particularly among young adults who smoke them for fun and the range of flavors.
“It’s long been known that smoking cigarettes is among the most significant risk factors for stroke. Our study shows that young smokers who also use e-cigarettes put themselves at an even greater risk,” explained lead investigator Tarang Parekh, MBBS, MSc. “This is an important message for young smokers who perceive e-cigarettes as less harmful ones and consider them a safer alternative.We have begun understanding the health impact of e-cigarettes and concomitant cigarette smoking, and it’s not good.”
“Our findings demonstrate an additive harmful effect of e-cigarettes on smokers’ blood vessels, hearts and brains,” explained Parekh.
“Consider this study as a wake-up call for young vapers, clinicians, and healthcare policymakers. There is an urgency to regulate such products to avoid economic and population heath consequences and a critical need to conduct further research on the benefits and risks of smoking cessation altermatives,” warned Parekh.

A new study has found that social media could be affecting the sleep of young adults.
The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.
“This is one of the first pieces of evidence that social media use really can influence your sleep.” said Jessica C Levenson. She was the lead author of a report on the study.
The researchers set out to examine the connection between social media use and sleep among young adults. Levenson noted that these young adults are possibly the first “generation to grow up with social media.”
The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media 30 times per week.”
Thirty percent of the study's participants reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.
Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be the most effective.
1.What's the main idea of the text?
A. The researchers focus on social media.
B. The researchers manage to handle sleep problems.
C. Doctors treat young patients.
D. Social media affects sleep.
2.When treating sleep problems, doctors are advised to ________.
A. offer some advice about giving up social media
B. ask the patients about young adults’ use of social media
C. give young adults some medicine
D. ask about the patients' living conditions
3.How did the researchers mainly carry out the study?
A. By doing online research. B. By giving an example.
C. By collecting published data. D. By doing questionnaires.
4.What can be inferred from the text?
A. Men are more likely to suffer from a sleep disorder than women.
B. People often using social media are less likely to have a sleep disorder.
C. Using computers less helps avoid sleep problems completely.
D. Sleep problems can be determined by the times of a person visiting social media.

A study has found that middle-aged and older adults who live in greener neighborhoods have a decreased risk of developing metabolic syndrome (代谢综合征) such as obesity, hypertension (高血压) and high blood sugar.
The study, published in Environmental Pollution, was conducted by the Barcelona Institute for Global Health (ISGlobal). It differed from previous studies on the health benefits of green spaces in that it examined all of the symptoms of metabolic syndrome together collectively rather than as individual components. Having metabolic syndrome increases a person’s risk for heart disease, stroke and type 2 diabetes, according to the National Heart, Lung, and Blood Institute.
The study from ISGlobal examined data from clinical examinations of over 6,000 British adults who were between 45 and 69 years old when the study began. The data was derived from four examinations participants went through between 1997 and 2013 that included blood analyses, blood pressure and measurements of weight. “These findings suggest that long-term exposure to green spaces can play an important role in preventing metabolic syndrome as a whole,” according to a press release published by ISGlobal.
The correlation between nearness to green spaces and better health could be associated with the expanded opportunities for physical recreation and lower exposure to air pollution, according to Carmen de Keijzer, ISGlobal researcher and principal author of the study.
Female subjects were more likely than males to exhibit the study’s association between living in greener neighborhoods and having fewer metabolic symptoms. “Women tend to spend more time in their residential neighborhood, which could explain this gender difference,” de Keijzer said. “We need greener cities if we want healthier cities.” de Keijzer added.
1.What do we know about the study from the first two paragraphs?
A.Young people were not included in the study.
B.Symptoms were examined one by one.
C.It was a joint effort of several institutes.
D.It was the first of its kind in decades.
2.What does the underlined word “derived” in Paragraph 3 mean?
A.Departed. B.Arrived.
C.Gained. D.Demanded.
3.Why do women have fewer metabolic symptoms?
A.Because they differ in gender.
B.Because they live in greener cities.
C.Because they live in healthier cities.
D.Because they stay more in where they live.
4.What can be a suitable title for the text?
A.Greener Neighborhoods, Fewer Metabolic Symptoms.
B.Women Having Fewer Metabolic Symptoms.
C.Metabolic Syndrome Increasing Heart Disease.
D.Living in Greener and Healthier Cities.

Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people’s behavior, judgment and they might contain important hidden truths as well.
“Psychologists’ explanations of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insight into themselves and their world,” said a lead author of the study Carey Morewedge, an assistant professor at Carnegie Mellon University.
In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing (揭示) the hidden truths about themselves and the rest of the world.
In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situation that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.
Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew.
The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.
“In other words,” said Morewedge, “people attribute meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.”
The researchers say that more investigation is needed to fully understand how people interpret their dreams. According to Morewedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.
1.. The purpose of the studies is to ________.
A. determine when people tend to remember their dreams
B. research whether dreams have anything to do with real life
C. find out how people explain their dreams and what impact that has
D. understand what causes people to dream and how to interpret dreams
2. According to the second experiment, what might influence people’s travel plans most?
A. Thinking about a past plane crash.
B. Dreaming about a plane crash.
C. Hearing a government’s warning of a terrorism risk.
D. Imagining a plane crashing on their planned route.
3.. What can be concluded from the study?
A. Dreams can be a useful tool for learning and problem solving.
B. Most people disagree that dreams help them better know themselves and the world.
C. A majority of people believes that dreams can predict their future and try to find their meaning.
D. When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less meaning to it.
4.. Which kind of dream is seen as more meaningful than the rest?
A. A pleasant dream about a person the dreamer likes.
B. A pleasant dream about a person the dreamer dislikes
C. An unpleasant dream about a person the dreamer likes.
D. An unpleasant dream about a person the dreamer dislikes.

New research, attempting to throw light upon how male and female brains differ, has found that timing is everything. American Vanderbilt University researchers Stephen Camarata and Richard Woodcock discovered that females have a significant advantage over males in timed tests and tasks. The study involved more than 8,000 males and females ranging in age from 2 to 90 from across the US.
“We found hardly any differences in overall intelligence. But we discovered that females performed better than men in time limited situations,” Camarata said, “It is very important for teachers to understand this difference in males and females when it comes to assigning work and tests.”
Many males can do a better job without strict time limits, added Camarata.
“Consider that many classroom activities, including testing, are directly or indirectly related to processing speed,” the researchers wrote in their report. “The higher performance in females may contribute to a classroom culture that favors females, not because of teacher bias(偏见)but because of inherent(与生俱来的)differences in gender processing speeds.”
The researchers found that males scored lower than females in all age groups in tests measuring processing speed. However, the study also found that males consistently outperformed females in some language abilities, such as identifying objects and knowing antonyms(反义词)and synonyms(同义词). The research contradicts the popular belief that girls develop all communication skills earlier than boys.
The researchers found no significant overall intelligence differences between males and females in any age groups.
“We believe there are fundamental differences in how male and female brains end up getting organized,” Camarata said, “Our next studies will give us some insight into where these processing differences are occurring.”
1.The new research referred to in the passage is intended to ________.
A. find whether age has something to do with people's intelligence
B. help teachers to assign work and arrange tests for students
C. find what's the differences between male and female brains
D. prove the differences in processing speed between males and females
2.The underlined word “outperformed” in the fifth paragraph probably means “________”.
A. to achieve better results than someone
B. to perform worse in some aspect than someone
C. to do something as well as someone
D. to be not so good at something as someone
3.People usually believe that ________.
A. there're hardly any differences between males' and females' overall intelligence
B. teachers favor girl students instead of boy students in schools
C. girls develop their language skills earlier than boys
D. females have a significant advantage over males in all subjects
4.Which of the following statements is TRUE according to the passage?
A. The researchers interviewed more than 8,000 males and females all over the world.
B. Generally speaking, males can do better jobs with strict time limits than females.
C. Females scored higher than males in any age groups in any situations.
D. The differences in gender processing speeds occur when people are born.
5.Which of the following can be inferred from the passage?
A. The researchers will continue to study how the gender differences in timing occur.
B. A female mathematician will make greater achievements than a male one.
C. School teachers have already known about these processing differences before.
D. If a girl has a higher processing speed than a boy, she must be more intelligent than him.

New research has found that grey seals can simulate(模仿）human speech and songs. The study carried out by Dr Amanda Stansbury and Professor Vincent Janik,at the University of St Andrews,found that grey seals use the same sound production system as humans due to having similar vocal tracts(声道）。
Three young grey seals-Zola,Gandalf and Janice-were monitored from birth by Stansbury and Janik to determine their natural talents.Once this process was complete, the researchers began teaching the seals to simulate common seal sounds or noises a seal might normally hear from a herd mate in the wild.Fish was used to encourage the seals to come out of the water and sing a series of notes.Stansbury would record the seals'own sounds and play them back.The seals quickly learnt that if they sang back the same notes, they would be rewarded with fish.
Once the seals were familiar with this process and could easily copy these basic sounds,Stansbury and Janik used higher and longer tones and unfamiliar vowels from human speech.The seals were then rewarded for matching these new sounds.Stansbury even used some combinations to simulate songs that no seal would be expected to produce under natural circumstances.Zola had a gift for copying up to ten notes of songs such as Twinkle,Twinkle,Little Star and the theme song of Star Wars.Gandalf and Janice were better at accurately reproducing combinations of human vowel sounds.
Stansbury said,"I was amazed how well the seals copied the model sounds we played to them.Copies were not perfect,but given that these are not typical seal sounds,it is pretty impressive.Our study really shows how flexible seal voices are."
After one year of working with the researchers,the seal pups were released back into the wild."This study gives us a better understanding of the development of vocal learning,a skill that is important for human language development."Janik believes this knowledge can help to develop new methods to study speech problems.
1.What is the first paragraph mainly about?
A.Grey seals 'learning environments.
B.A research finding on grey seals.
C.Humans 'sound production system.
D.A comparison of humans and grey seals.
2.In the study,fish would be given when the seals

C.repeated the same notes D.copied typical fish sounds
3.What can we find about Zola based on the research?
A.It can copy some musical sounds played to her.
B.It is good at copying human vowel sounds.
C.It is smarter than Gandalf and Janice.
D.It likes singing children's songs.
4.What does Janik think of the research result?
A.It shows the living environments of grey seals.
B.It leads to a better understanding of human vocal system.
C.It raises an awareness of the need to protect grey seals.
D.It brings inspirations for research on speech problems.

Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．
"Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．
Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．
That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．
That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．
Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．
1.From the passage we know that .
A．physically active kids get into less trouble
B．more skating parks are being built
C．kids who spend hours watching TV benefit a lot
D．kids who have nowhere to skate tend to take drugs
2.If your kid is a football player, he is more likely to ____
A．get into the habit of smoking or drinking
B．develop teamwork spirit
C．have risky behaviors
D．fail in the schoolwork
3.This passage is mainly written to ___ ．
A．offer some information to teachers and parents
B．persuade kids not to watch a lot of TV
C．urge the public to help children be active
D．show the author's concern about children's growth
4.What does the underlined sentence "which adults sometimes frown upon" in the 4th paragraph mean?
A．Some adults don't understand the sports．
B．Some adults are impatient with kids．
C．Adults consider it dangerous to go skating or skateboarding.
D．Some adults think them related to bad behaviors.
5.It can be inferred from the passage that .
A．kids are not expected to be active by some parents
B．professor Penny is a famous writer and journalist
C．skateboarding is popular in schools and communities
D．kids are not encouraged to join the football team
