Intelligence Changes in the Digital Age
zài在èr shí shì jì二十世纪 ，rén人de的zhì shāng智商fēn shù分数yì zhí一直zài在shàng shēng上升 ，dàn但zuì jìn最近èr shí二十nián年 ，hěn很duō多fā dá guó jiā发达国家de的zhì shāng智商fēn shù分数kāi shǐ开始xià jiàng下降 。
In the twentieth century, people's IQ scores kept rising, but in the past twenty years, IQ scores in many developed countries have started to decline.
kē xué jiā科学家fā xiàn发现 ，zhè这bú shì不是yīn wèi因为jī yīn基因 ，ér shì而是yīn wèi因为huán jìng环境 、shè huì社会hé和shù zì数字jì shù技术de的biàn huà变化 。
Scientists have found that this is not due to genetics, but because of changes in environment, society, and digital technology.
bǐ rú比如 ，hái zi men孩子们yòng用shǒu jī手机hé和diàn nǎo电脑de的shí jiān时间biàn变duō多le了 ，zhù yì lì注意力hé和jì yì lì记忆力biàn变chà差le了 。
For example, children are spending more time on phones and computers, which has worsened their attention and memory.
hái yǒu还有 ，chī吃de的shí wù食物bù不jiàn kāng健康 ，quē shǎo缺少tiě铁 、xīn锌děng等yíng yǎng营养 ，yě也huì会yǐng xiǎng影响dà nǎo大脑fā yù发育 。
Also, unhealthy diets lacking nutrients like iron and zinc can affect brain development.
zài在ōu zhōu欧洲hé和běi měi北美 ，zhì shāng智商xià jiàng下降zuì最míng xiǎn明显 。
The IQ decline is most obvious in Europe and North America.
zài在zhōng guó中国hé和yī xiē一些fā zhǎn zhōng guó jiā发展中国家 ，zhì shāng智商hái还zài在màn màn慢慢shàng shēng上升 ，dàn但zài在dà chéng shì大城市 ，shù zì huà数字化hé和wū rǎn污染ràng让jìn bù进步biàn变màn慢le了 。
In China and some developing countries, IQ is still slowly rising, but in big cities, digitalization and pollution have slowed progress.
zhuān jiā专家men们jiàn yì建议 ，xué xiào学校yào要gǎi jìn改进jiào xué教学fāng fǎ方法 ，jiā zhǎng家长yào要zhù yì注意hái zi孩子de的yǐn shí饮食hé和yòng用diàn zi电子chǎn pǐn产品de的shí jiān时间 。
Experts suggest that schools should improve teaching methods, and parents should pay attention to their children's diet and screen time.
wǒ men我们yào要bǎo hù保护dà nǎo大脑jiàn kāng健康 ，ràng让dà jiā大家zài在shù zì数字shí dài时代yě也néng能xué学dé得hǎo好 ，sī kǎo思考dé得gēng shēn更深 。
We need to protect brain health so that everyone can learn well and think deeply in the digital age.
