It is believed that around half the US adult population will be obese (肥胖的) by 2030, while one in four will fall into the severely obese category. This is according to a new study led by the Harvard T.H. Chan School of Public Health, which found that levels of obesity are increasing in every state. Indeed the predictions show that levels of severe obesity could be higher than 25 percent in half of states.
“Especially striking was our finding that among adults with very low income (less than $20,000 per year), severe obesity is predicted to be the most common in 44 states—almost everywhere in the US,” a researcher said.
The research was carried out to inform state policymakers—and perhaps help change the tendency. The study authors say the best form of attack is prevention. Limiting intake of sugar is stressed as one of the most effective and cost-effective methods for reducing obesity levels, and a tax likely to save more money than it costs.
Sugar (and the sugar industry) has come under fire for its role in promoting obesity. Indeed, one recent study published in September 2019 puts responsibility for today’s obesity epidemic (流行病) firmly on the shoulders of sugar, concluding high-sugar diets during childhood in the seventies and eighties could be behind the rise.
“We knew from previous work that obesity is increasing in the US, and that some states and demographic groups (人群) are at higher risk, but we were surprised that even the states with the lowest obesity will be above 35 percent in 2030—a level currently considered high, a researcher told Newsweek. What is clear is that we will not be able to treat our way out of this epidemic—achieving and keeping weight loss is difficult—so prevention efforts will be key to making progress in this area.”
1.What’s the most surprising finding in the study?
A.Over 25% of people will be seriously obese.
B.Levels of obesity are increasing in every state.
C.poor adults are more likely to be severely obese.
D.Half of the US adults will be overweight by 2030.
2.What is the best way to solve the problem according to the passage?
A.To reduce the tax. B.To limit intake of sugar.
C.To reduce obesity level. D.To inform policymakers.
3.What does the underlined word “fire” actually refer to in paragraph 4?
A.Blame from researchers. B.Rapid chemical change.
C.Current obesity epidemic. D.High-sugar diets.
4.What’s the main idea of the last two paragraphs?
A.Obesity is increasing everywhere in the US.
B.All states in America are at the same level of obesity.
C.Maintaining weight loss is a good way to deal with obesity.
D.Diets with less sugar are vital to preventing the problem of obesity.

It is estimated that more than half the world’s population is bilingual (双语的), and in an increasingly globalised world, there are obvious benefits of speaking more than one language. However, for many years, parents were advised not to teach their children to speak more than one language from birth. Learning two or more languages simultaneously (同时) was believed to cause confusion and slow down academic development. While it is certainly true that children who are learning to speak more than one language as their mother tongue will often mix the languages up or speak a little later, these are temporary problems, and there is no reason to avoid teaching a child more than one language.
In fact, there are plenty of reasons to encourage your child to become bilingual from birth. As well as the obvious benefits of being able to communicate with more people, and the possibility of earning more money, children who speak more than one language have been shown to score more highly in achievement tests at school. This is true for mathematics as well as tests of verbal (言语的) skills.
And in later life it has been found that bilinguals, on average, will tend to develop Alzheimer’s disease five years later than monolingual speakers. Speaking three or more languages offers even more protection. It seems that the increased number of connections within the brain allows bilinguals to cope better with brain damage.
But is it too late if you haven’t already learned a second language in childhood? It used to be thought that the adult brain was very fixed, but recent research has shown that we continue to develop new connections in the brain throughout our lives, meaning that it’s perfectly possible to learn another language to a high standard. Older learners are less likely to have native-like pronunciation, but they are better at learning vocabulary as they are able to use far more skills and strategies than children. And learning a language is like using a muscle – the more you use it, the stronger it gets, meaning that you will find your third language easier than your second, and so on.
1.Why shouldn’t parents be discouraged from teaching their children to be a bilingual?
A. Children’s confusion over two languages will not last long.
B. Children will not mistake one language for the other.
C. Parents should begin to teach a second language early.
D. Parents’ guidance will help children tell two languages apart.
2.Which of the following is NOT a possible benefit of being a bilingual?
A. A bilingual is less likely to develop Alzheimer’s disease.
B. A bilingual child may do well in mathematics at school.
C. A bilingual will probably make more money.
D. A bilingual child owns relatively good language ability.
3.Compared with children, adult language learners ___________.
A. are slower at learning a second language.
B. are more skilled at building vocabulary.
C. are more likely to acquire a native accent.
D. are slower at making logic connections.
4.What can be learned from the passage?
A. A bilingual child will speak both the languages badly later in his life.
B. Learning a second language certainly contributes to your body fitness.
C. Connections within adults’ brain will permanently stop developing.
D. With each language learned, the learning process will become easier.

For the first time in modern history, less than half of the U.S. adult population now reads literature, according to a recent survey. Reading at Risk: A survey of Literary Reading in America presents a detailed review of the decline of reading’s role in the nation’s culture.
Reading at Risk is a survey of national fashion in adult literary reading. The data source for Reading at Risk is as reliable and objective (客观的) as any such survey can be. The key results of the survey are presented in the “Summary”, but the report can be further explained as: literary reading in America is not only declining rapidly among all groups, but the rate of decline has been speeded up, especially among the young. Reading at Risk merely shows a great cultural change that most Americans have already noted － our society’s great turn to electronic media for entertainment and information.
Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat (减少) from participation in public and cultural life.
What is to be done? There is surely no single solution to the present problem, just as there is no single cause. The important thing now is to understand that America can no longer take active and devoted reading for granted.
Reading is not a timeless, common ability. As more Americans lose that ability, our nation becomes less informed, active, and independent minded. These are not qualities that a free, inventive, or productive society can afford to lose.
1.The main purpose of the survey is to __________.
A. focus on the role of electronic media and reading
B. show that American young people read less and less
C. give a report of the national fashion of literary reading
D. review that less than half of the population now reads literature
2.According to the passage, reading __________.
A. requires less attention and devotion
B. demands no more than passive participation
C. limits various communications and views
D. means active participation in public and cultural life
3.The underlined phrase “cultural change” in Paragraph 2 refers to the change __________.
A. from oral culture to electronic media
B. from print culture to electronic media
C. from electronic media to oral culture
D. from electronic media to print culture
4.The author of the passage __________.
A. misunderstands oral culture
B. doubts the results of the survey
C. encourages the Americans to read more
D. agrees to the solution to the present problem in reading
