    A new study has found evidence of aggressive behaviour in children who drink four or more cups of soft drinks per day. The information for the study came from the mothers of 3,000 five-year-olds.

Researchers asked the mothers to keep a record of how many glasses of soft drinks their children drank over a two-month period. The mothers were also asked to complete a list of their children’s behaviour. The researchers found that 43 percent of the youngsters drank at least one glass of sodas every day, and four percent of the youngsters had four or more sodas to drink every day.

Shakira Suglia worked on the study with researchers from the University of Vermont and Harvard University School of Public Health. She says they have found that children who drank the most sodas were more than twice as likely as those who drank no soda to show signs of aggression. “For the children who drank four or more soft drinks per day, we see a connection between aggressive behaviour, attention problems and withdrawn(沉默寡言的)behaviour.”

The aggressive behaviour includes destroying things belonging to others and physically attacking(攻击)people.

Doctor Suglia says it is not clear why young children who drink a lot of sodas have behaviour problems. “We can’t prove that this is a direct cause and effect relationship. There are a lot of ingredients(成分)in sodas, a lot of ingredients that have not been examined in relation to behaviour.”

Caffeine is often found in soft drinks, which helps to make people feel energetic. Doctor Suglia says that caffeine could be causing the five-year-olds to be more aggressive. Earlier studies of young adults have found the highest sugar levels in those who carry weapons and show signs of bad social behaviour.

1.If a teenager drinks a lot of soft drinks, what will he/she be like?

Find it hard to tell right from wrong.

Stay alone and speak little.

Have reading difficulties.

Have difficulty in concentrating.

A.①③ B.②④

C.③④ D.①②

2.What is aggressive behaviour according to the passage?

A.Protecting oneself from being hit. B.Behaving more confidently.

C.Doing harm to others. D.Saying impolite words to other.

3.What have the researchers found?

A.A lot of ingredients in soft drinks can make people feel energetic.

B.Caffeine may lead to children’s behaviour problems.

C.Having a lot of soft drinks may be bad for the memory.

D.Soft drinks are not good for the health.

4.What is the best title for the passage?

A.Children Who Are Active Show More Bad Behaviour

B.The Relationship between Caffeine and Health

C.How to Keep Children Away from Soft Drinks

D.Children Who Drink Lots of Soft Drinks Are More Likely to Be Aggressive

 

1.B 2.C 3.B 4.D 【解析】 这是一篇说明文。一项新的研究发现,如果孩子每天喝太多的软饮料,他们就有可能出现攻击性行为、注意力问题以及沉默寡言的现象。专家认为软饮料中的咖啡因可能是引起这些现象的原因。 1.细节理解题。根据文章第三段最后一句“For the children who drank four or more soft drinks per day, we see a connection between aggressive behaviour, attention problems and withdrawn(沉默寡言的)behaviour.”可知,如果孩子每天喝四杯或四杯以上的软饮料,就会出现攻击性行为、注意力问题和沉默寡言的现象,所以②和④正确。故选B。 2.推理判断题。根据文章第四段“The aggressive behaviour includes destroying things belonging to others and physically attacking(攻击)people.”可知,这种攻击行为包括破坏属于别人的东西和人身攻击。结合选项,C(伤害别人)属于此范畴。故选C。 3.细节理解题。根据文章第六段中的“Doctor Suglia says that caffeine could be causing the five-year-olds lo be more aggressive” 可知,咖啡因可能会使5岁的孩子变得更有攻击性。B(咖啡因可能会导致儿童的行为问题)与之表达意思一致。故选B。 4.主旨大意题。这篇文章主要介绍了一项研究结果。文章第一段(A new study has found evidence of aggressive behaviour in children who drink four or more cups of soft drinks per day)即是中心段:该项研究表明,已有证据证明如果一个孩子喝了太多的软饮料,他就非常有可能表现出攻击性行为。结合选项,D(喝大量软饮料的儿童更有可能具有攻击性)表达此意。故选D。

Social media and teens’ anxiety

From cyber-bullying to cruel comments, social media can be a land mine for kids. Issues parents never worried about are now a risk for many teens. With kids’ digital well-being a concern, researchers are exploring potential links between social media and the rise in teen suicide rates, tech addiction, and loss of real-life social skills. Many parents are wondering: Is social media causing my kid to have anxiety?

It’s a question that worried parents. Some research has observed a relationship between social media use and anxiety in kids, but it’s difficult to know if and when social media causes anxiety or whether kids who are anxious turn to social media as a way to seek support. How kids use social media matters, too. Social comparison and feedback-seeking behaviors have been associated with depressive symptoms, which often co-occur with anxiety.

How can parents keep social media a positive for kids?

1. Seeing photos of a trip to the beach your friends didn’t invite you to can really be upsetting. If your kid is tired of digital drama, suggest they take a break from social media for a while. In fact, if they post a status update that they’re taking a break, their friends might be very accepting because they’ve had similar feelings.

2. People post stuff that makes their lives look perfect — not the homework struggles, or the fight they had with their dad. Remind kids that social media leaves the messy stuff out — and that everyone has ups and downs.

3. In a world where kids could spend their days lying around looking at Wechat, it’s doubly important for them to feel as though they’re cultivating their inner lives. Prompt them to balance social media with soul-nourishing activities such as hobbies, exercise, reading, and helping others. Otherwise, what are they going to show off about on social media?

Vitamin D3 Improve Heart Function

A daily dose of vitamin D3 improves heart function in people with heart failure, a five-year University of Leeds research project has found.

Dr. Klaus Witte, from the School of Medicine and Consultant Cardiologist at Leeds Teaching Hospitals NHS Trust, led the study. He said: “This is a significant breakthrough for patients. It is the first evidence that vitamin D3 can improve heart function of people with heart muscle weakness –known as heart failure.” 1.

Vitamin D3 can be boosted by exposure to sunlight, but heart failure patients are often deficient in it even during the summer because older people make less vitamin D3 in response to sunlight than younger people. Vitamin D3 production in the skin is also reduced by sunscreen.

The study, which was funded by the Medical Research Council, involved more than 160 patients from Leeds who were already being treated for their heart failure using proven treatments including beta — blockers, ACE-inhibitors and pacemakers. 2. Those patients who took vitamin D3 experienced an improvement in heart function which was not seen in those who took a placebo.

3. Heart specialists measure heart function by taking an ultrasound scan of the heart and measuring how much blood pumps from the heart with each heartbeat, known as ejection fraction. The ejection fraction of a healthy person is usually between 60% and 70%. In heart failure patients, the ejection fraction is often significantly impaired — in the patients enrolled into the study the average ejection fraction was 26%.

In the 80 patients who took Vitamin D3, the heart’s pumping function improved from 26% to 34%. 4. This means that for some heart disease patients, taking vitamin D3 regularly may lessen the need for them to be fitted with an implantable cardioverter defibrillator (ICD), a device which detects dangerous irregular heart rhythms and can shock the heart to restore a normal rhythm.

A. Heart failure can by all means be cured by Vitamin D3.

B. Changes in heart function were measured by ultrasound.

C. In the others, who took placebo, there was no change in cardiac function.

D. Participants were asked to take vitamin D3 or a placebo tablet for one year.

E. Sunscreen will prevent people from absorbing more Vitamin D3 to a great extent.

F. The finding could make a significant difference to the care of heart failure patients.
