Annoying brother or sister may break your toys, but he or she may help you when you are in trouble. A new study suggests that younger siblings might be good for your health.

Children who didn't welcome a baby brother or sister into the family before first grade had almost three times the likelihood of obesity compared with kids who experienced the birth of a sibling when they were around 3 to 4 years old, the study found.

“It is possibly because when there is a younger sibling in the family, a child might become more active—for example, running around more with their younger sibling,” said Julie Lumeng, a public health researcher at the University of Michigan.

“Maybe families are more likely to take the kids to the park when there is a younger sibling, or maybe the child is less likely to sit, watching TV, when there is a younger sibling to ask them to join more active pretend play,” she added.

Mealtimes might also be different with a second kid at the table.Parents of only child can often focus too much on what their kid eats, which can lead to bad eating habits, some previous research suggests.

“When parents use restrictive or pressure­to­eat feeding practices, children have an increased risk of being overweight,” said Jerica Berge, a researcher at the University of Minnesota.

“When a new child is introduced, parents may relax their focus on the older child's eating behaviors, making it possible for the older child to self­regulate their eating,” said Berge. “This self­regulation may lead to a healthier weight for the child with a sibling.”

For their study, Lumeng and colleagues followed 697 U.S. children from birth through age 6.However,the authors acknowledged that their study lacked objectively measured birth weights and information on events such as a divorce, a move or a job loss in the family—all of which can influence the odds of children becoming obese.

文章大意:这是一篇议论文。文章主要围绕加工食品是否会让人上瘾的问题展开,论述了不同的人对此的不同看法,作者建议人们吃更健康的食物。

【推荐1】Food scientists studied what Americans eat. They found that most of the calories people eat come from ultra-processed foods. Processed foods include large amounts of sugar, salt, oils, fats, and other additives. Highly processed foods are a large part of the American diet. Scientists link them to obesity, heart disease, Type 2 diabetes, and other physical diseases.

Some scientists say these foods are not just tempting but also are addictive. Other scientists disagree. A recent journal article explored the science behind food addiction. It also asked if processed foods might contribute to overeating and obesity.

One opinion was that certain foods did create addictive behavior. At the top of the list were pizza, chocolate, potato chips, cookies, ice cream, French fries, and cheeseburgers. These foods share much in common with addictive substances. The bloodstream absorbs them. They light up parts of the brain that regulate reward, emotion, and motivation.

Another doctor says these foods are not addictive. The reason is that processed foods do not change minds the way smoking a cigarette or drinking a glass of wine can affect the mind. Mind-changing substances cause a sensation in the brain that processed foods do not, he says.

This doctor says that food industry drives overeating. It markets more than 20,000 new products every year. People have access to an endless variety of foods and drinks. People are urged to buy and eat. “It is the diversity of foods that is so appealing and causing the problem,” he says.

But you do long for processed food. If you want to kick a processed food habit, you have to do something about it. One idea is to keep a record of the foods you are thirsty for. Keep processed foods out of your house. And, of course, eat healthier foods.

1. What can we learn about ultra-processed foods?
A.They are healthy.B.They are nutritious.
C.They are rich in calories.D.They are green.
2. What does the underlined word “tempting” in paragraph 2 probably mean?
A.Amazing.B.Entertaining.C.Annoying.D.Inviting.
3. What may cause the problem of overeating according to paragraph 5?
A.Food variety.B.Food brand.C.People’s preference.D.Social needs.
4. What would be a suitable title for the text?
A.Do you like processed foods?B.Are processed foods addictive?
C.Are doctors for processed foods?D.Do you want to kick a bad habit?

【推荐2】Scientists in Argentina have created the world’s first cow with two human genes that will enable it to produce human­like milk.

Genetic engineering was used to introduce the “mothers’ milk” genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.

As an adult, the cloned cow “will produce milk that is similar to that of humans”, which will prove “a development of great importance for the nutrition of infants (婴儿)”, said the institute. “The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk,” said the statement.

In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more_closely_resemble that of humans.

“Our goal was to raise the nutrition value of cows’ milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.

Cristina Kirchner, President of Argentina, said the scientific institute made all Argentines proud. She also said that she had rejected the “honor” of having the cow named after her. “They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”

1. What is the passage mainly about?
A.The importance of genetic engineering.
B.Ways to improve mothers’ milk.
C.A cloned cow to produce human­like milk.
D.Advanced agricultural technology in Argentina.
2. Which of the following can best replace “more closely resemble” in Paragraph 4?
A.have more varieties than
B.be more similar to
C.have more nutrition than
D.be more different from
3. What can be inferred from Cristina Kirchner’s statements?
A.She was quite satisfied with the research done by the institute.
B.She considered it an honor to name the special cow.
C.She felt it improper to be named after the cow.
D.She refused to give a name to the cow out of self­respect.
