What does the word “snowball” in Paragraph three most probably mean.第一次Why do smokers tend to weigh less than nonsmokers and gain weight when they give up the habit?Contrary to “common knowledge”, nonsmokers do not generally eat more than smokers, nor do they exercise less, studies find. Research performed on smokers at rest indicates that nicotine (尼古丁) itself can increase basal metabolic (新陈代谢的) rates, meaning smokers burn more energy than nonsmokers during periods of inactivity. But surveys suggest most smokers smoke not while completely at rest, but while performing light activities such as desk work that can increase metabolic rates by two or three times. Unless nicotine’s metabolic effects increase proportionally with metabolic rates, its influence on weight might be insignificant.Now a study shows that nicotine’s effects on body-fuel consumption indeed increase proportionally with increases in activity. “These results indicate that the metabolic effect of nicotine may play a greater part in accounting for body-weight differences between smokers and nonsmokers than was previously believed,” says Kenneth A. Perkins and his colleagues at the University of Pittsburgh School of Medicine.

Psychologists (心理学家) have found that how much people smile in old photos can predict their later success in marriage. In one test, the researchers looked at people's college yearbook photos, and rated their smile intensity from 1 to 10. Scoring was based on the stretch in two muscles: one that pulls up on the mouth, and one that creates wrinkles around the eyes. None of the people who fell within the top 10 percent of smile strength had divorced, while within the bottom 10 percent of smilers, almost one in four had had a marriage that ended, the researchers say. In a second trial, the research team asked people over age 65 to provide photos from their childhood. The researchers scored each person's smile, and found that only 11 percent of the biggest smilers had been divorced, while 31 percent of the frowners had experienced a broken marriage. Overall, the results indicate that people who frown in photos are five times more likely to get a divorce than people who smile. While the connection is striking, the researchers stress that they can't conclude anything about the cause of the correlation (相关性). "Maybe smiling represents a positive disposition (性格) towards life," said study leader Matthew Hertenstein, a psychologist at DePauw University in Indiana. "Or maybe people who smile more often tend to attract more friends, and a larger support network makes it easier to keep a marriage healthy." Hertenstein said he has considered other explanations, such as the possibility that people who smile when a photographer tells them to may have gentle personalities, which makes marriage easier. The results of the study fit into a larger pattern of research that has found many personality characteristics can be determined from very thin slices of behavior. Basically, we often reveal ourselves in the most subtle, simple ways. And smiling in photos has been shown to be connected with a number of traits, including a generally happier disposition. "I think our results go along with a lot of the literature that's been coming out over the last 5 to 10 years, which shows that positive emotionality is incredibly important in our lives," Hertenstein told Live Science. "There are many, many beneficial outcomes to a positive disposition."1. The final purpose for the researchers to score people's smiles is to ________.A) help people predict whether their marriage will surviveB) find out whether smiles relate to marriage outcomes C) find out whether people were happy at their early ageD) reveal whether smiling presents a happier personality2. What do the researchers conclude through the two tests?A) People who smile more often are likely to have a lasting marriage. B) People who frown in their old photos will get a divorce in future.C) Even the biggest smilers might also experience divorce.D) Most frowners take a passive attitude towards marriage.3. According to Hertenstein, why is smiling connected with marriage success?A) Because smiling people have more supporting friends.B) Because smiling people are easy-going and gentle.C) Because smiling people have happier personality.D) He does not know the exact reason for sure. 4. What is the implication of Hertenstein's research and the other similar study?A) It's usually hard to conceal one's personality.B) It's beneficial to reveal our true emotions.C) It's significant to have a positive personality. D) It's important to pay attention to our daily behavior.5. Which one of the following is the best title for the passage?A) Smiles and Personality.B) Smiles and Old Photos.C) Old Photos Predict Personality.D) Smiles Predict Marriage Success.

An entire industry has been developed to provide educational DVDs designed for infants. These DVDs are marketed as able to facilitate the development of various cognitive (认知的) skills such as language. An academic journal recently published a study that focused on one product, the Baby Wordsworth, from the Walt Disney Company's Baby Einstein series. The study put the DVD to the test with a group of one- and two-year-olds. For six weeks, 88 children were randomly (随机地) assigned to either watching it a few times a week or not at all. Researchers then tested the language skills in each group based on how many words the children knew. At the end of the period, children in both groups understood about 20 of the 30 words highlighted in the DVD, on average. The researchers also asked parents about their children's television viewing before entering the study. The earlier a child started watching Baby Einstein DVDs, it turned out, the smaller his or her vocabulary was. The study's finding is in line with some earlier research, says Rebekah Richert, a researcher at the University of California, who led the study, but it is unclear if the DVDs themselves are responsible. "Parents who place their kids in front of the screen could be trying to remedy slow language development, or they could be using the DVDs as baby sitters, cutting back on social stimulation." "A lot of children seem to have these kinds of DVDs," Richert says. "My take-home message would be to encourage live interaction between parent and child." Although it is not well understood how watching television affects language, Richert and his colleagues wrote in their report, the American Academy of Pediatrics (儿科) recommends that children younger than two stay away from the screen. The Baby Einstein Company emphasized that it "does not claim educational outcomes." On its web page, it notes that its products "are not designed to make babies smarter but to engage them." The company notes that it disagrees with the recommendation from the American Academy of Pediatrics. "When used properly," the company writes, "appropriate video content can be a useful tool for parents and little ones to enjoy together."1. Researchers conducted the study with the Baby Wordsworth DVD in order to ________.A) examine the quality of the DVD from the Baby Einstein CompanyB) reveal the difference in language learning ability between babiesC) find out whether the Baby Wordsworth DVD can boost language skills D) find out how many words babies can learn from the DVD2. It can be inferred that the previous studies have suggested that ________.A) early exposure to DVDs can negatively impact language development B) watching baby videos can actually boost the children' language skillsC) baby videos are harmful to the cognitive learning of childrenD) DVDs of poor quality can not facilitate language development3. Which of the following is the possible reason given by Richert to explain the results of his study?A) Putting babies in front of educational DVDs kills their interest in language learning.B) Keeping kids watching DVDs reduces parents' verbal engagement with them. C) Children under two cannot concentrate on educational DVDs.D) Kids at an early age show no much difference in language learning.4. According to Richert, what is the most important thing for parents to do?A) Keeping infants away from the educational DVDs.B) Staying together with babies in front of the screen.C) Having more interaction with children in real life. D) Limiting the video watching time for young kids.5. What does the Baby Einstein Company say about its DVD products?A) They are helpful for the kids who have language delay.B) They are harmful to young kids without a proper use.C) They cannot help the language learning of young kids.D) They are not made to improve the intelligence of kids.
