Speaking two languages can actually help offset(抵消) some effects of aging on the brain, a new study has found.

Researchers tested how long it took participants to switch from one cognitive(認(rèn)知的) task to another, something that’s known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky.

Gold’s team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental activities faster than those didn’t. The study only looked at life-long bilinguals, defined in study as people who had spoken a second language daily since they were at least 10 years old.

Gold and his team asked 30 people, either bilingual or monolingual, to have a series of tests. They found that bilingual people were not only able to switch tasks faster, they had different brain activity than their monolingual peers.

Kristina called bilingualism "a beautiful natural experiment”, because people grow up speaking two languages, and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them.

Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion（專心）would somehow hinder his ability to learn English.

"Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial.”

1. What’s the main idea of the passage?

A. Researchers found that bilingual people can slow down the speed or aging on the brain and respond fast.

B. Researchers found that bilingual people respond slowly.

C. Researchers found that speaking two languages is important.

D. Researchers found that bilingual people are great.

2.Which of the following is TRUE according to the passage?

A. Older bilinguals can’t respond faster in mind.

B. Young bilinguals can respond faster in mind than those monolinguals.

C. Older adults speaking a second language daily since they were at least 10 years old can respond faster than those who don't.

D. Bilingual children respond slower in mind than those monolinguals.

3. In Gold’s opinion, learning a second language in childhood is______.

A．dangerous to children

B. not beneficial to children

C. dangerous but beneficial to children

D. not dangerous but beneficial to children

Adding math talk to story time at home is a winning factor for children’s math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together.

Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app’s effect was especially strong for children whose parents tend to be anxious or uncomfortable with math.

Previous research from this group has demonstrated the importance of adults’ attitudes about math for children’s math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children’s math achievement.

The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents’ uneasiness about math and children’s low math achievement.

“Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math,” said Beilock, professor in Psychology and author of Choke, a book about stress and performance. “These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way.”

Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children’s math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math.

The more times parents and children in the math group used the app, the higher children’s achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year’s end.

1.Bedtime Math is an iPad app that _____.

A. requires parents and children to answer reading comprehension questions

B. assesses children’s math achievement and parents’ nervousness with math

C. teaches children how to count, recognize shapes and solve practical problems

D. encourages children together with their parents to solve math story problems

2.The previous study found that _____.

A. help from math-anxious parents improves children’s math achievement

B. children’s math achievement is related to parents’ attitude about math

C. interactions around math at home will cut off the family relationship

D. children can achieve more success if they see the importance of math

3.We can infer from the passage that ______.

A. children using the app for three months can see gains in math achievement

B. children whose parents are uneasy about math outperform other students

C. it is the math problems related to the stories that make the great difference

D. the frequency of using the app has nothing to do with children’s achievement

4.Which is the best title for the passage?

A. High-quality math interactions improve performance.

B. Frequent use of app can develop problem solving ability.

C. Low-effort activities create good parent-child relationship.

D. High-anxiety parents influence children’s attitude about math.
