In recent years, short-form videos have become popular around the pared with traditional long-form videos, they are more convenient.
However, some Chinese researchers have some worries. They have recently studied how short-form videos reshape our brains and influence our genes. The new study found that watching short-form videos could increase brain activity (活跃性). This may lead to various biological and nervous system problems.
For the study, the researchers picked out 111 college students between the ages of 17 and 30 who liked to use social media. Researchers collected their brain imaging data using MRI scans (磁共振扫描) to see the nerve system effects of short-form videos, especially in terms of structural changes and functional activity in the brain.
The results were astonishing. Students who spent more time on short-form videos had different brain structures and functions from others. There is an increase in gray matter in two brain regions, which help people make decisions, deal with information and control their emotions. This change makes the brain more sensitive to the quick pleasure of watching one video after another. That’s why it’s harder for these students to stop using short-form video apps.
Moreover, the researchers found nearly 500 genes that are related to brain changes from short-form video addiction. Interestingly, most of these genes show greater activity when people are teenagers. This shows that the teenage years are a weak period—people at this age may be more likely to get addicted to short-form videos.
31．What did the research mainly study
A．Basic structure of human brains.
B．Common behaviours of the teenagers.
C．Influences of short-form videos on our brains.
D．Popularity of short-form videos among the young.
32．What does the underlined word “astonishing” mean
A．Surprising. B．Boring. C．Common. D．Simple.
33．What does more brain sensitivity lead to
A．Easier addiction. B．Faster learning. C．Better decisions. D．Calmer emotions.
34．Why might teenagers be more easily addicted to short-form videos
A．Because they use mobile phones more frequently.
B．Because they have more free time to use apps.
C．Because some genes are more active at their age.
D．Because the brain development is largely complete.
35．Which of the following is most likely to be shown next
A．Ways for doctors to treat video addiction symptoms.
B．Methods for parents to manage their own video use time.
C．Advice for teenagers to reduce short-form video addiction.
D．Tips for schools to educate all the people on video risks.
【答案】31．C 32．A 33．A 34．C 35．C

【详解】31．细节理解题。根据“They have recently studied how short-form videos reshape our brains and influence our genes.”可知，该研究主要探讨短视频对我们大脑的影响。故选C。
32．词句猜测题。根据“Students who spent more time on short-form videos had different brain structures and functions from others.”可知，长时间看短视频的学生大脑结构和功能与他人不同，这一结果是令人意外的。“astonishing”意为“令人惊讶的”，与“Surprising”同义。故选A。

34．细节理解题。根据“most of these genes show greater activity when people are teenagers. This shows that the teenage years are a weak period—people at this age may be more likely to get addicted to short-form videos.”可知，青少年更易沉迷短视频是因为他们这个年龄段，与短视频成瘾相关的部分基因更活跃。故选C。
35．推理判断题。文章最后重点指出青少年更易沉迷短视频，结合前文对短视频负面影响的研究，接下来最可能给出针对青少年减少短视频成瘾的建议。故选C。

【导语】本文主要介绍了一种特殊的服务——未来邮件。
【详解】51．句意：你梦想过在未来给自己寄一封信吗？根据“Do you dream of posting a letter to...in the future ”可知，此处指给自己写信，应用反身代词，you的反身代词为yourself。故填yourself。
52．句意：它能按照人们希望的速度尽可能慢地寄信。根据“It can send letters as...as people want.”可知，as...as“和……一样”，中间接形容词/副词原级，此处修饰动词send，需用副词形式，slow的副词形式为slowly。故填slowly。
53．句意：人们可以决定信件什么时候送达，可能是一年后，甚至十年后。根据“People can decide...the letters arrive, in one year or even ten years.”可知，此处为宾语从句，从句中缺少时间状语，表示决定信件何时送达。故填when。
54．句意：通常，这些信件是友情和爱的提醒。根据“the letters are reminders of...and love.”可知，此处应用名词与love为并列关系，love为抽象名词，此处应用friend的抽象名词friendship。故填friendship。
55．句意：比如，山西的一名学生Li Zixuan上周给明年的母亲节寄了一封信给她妈妈。根据时间状语“last week”可知，此处为一般过去时态，应用谓语动词过去式，send的过去式为sent。故填sent。
56．句意：他们总是期待收到这些信。根据“They always expect...the letters.”可知，expect to do sth.“期待做某事”，此处应用动词不定式。故填to get。
57．句意：通过这些信，他们可以看看自己的生活是否和之前期待的一样，并思考时间的意义。根据“think about the...of time.”可知，定冠词the后接名词，动词mean的名词形式是meaning。故填meaning。
58．句意：现在，在很多城市，人们可以轻松地使用这项服务。根据“people can use the service...”可知，副词修饰动词，easy的副词为easily。故填easily。
59．句意：但如果我收不到信，我也不会太难过。根据“But I won’t be too sad...I can’t.”可知，本句为if引导的条件状语从句，主句用一般将来时/情态动词，从句用一般现在时。故填if。
60．句意：比起收到信，最重要的事情是写信时的那份情感。根据“Compared to receiving a letter, the...thing is the feelings of writing the letter”可知，定冠词the后接最高级，important是多音节形容词，最高级形式为most important。故填most important。
六、完成句子（本大题共5小题，每小题2分，满分10分）
61．他看起来很疲惫，也许他昨晚熬夜了。

In recent years, short-form videos have become popular around the pared with traditional long-form videos, they are more convenient.
However, some Chinese researchers have some worries. They have recently studied how short-form videos reshape our brains and influence our genes. The new study found that watching short-form videos could increase brain activity (活跃性). This may lead to various biological and nervous system problems.
For the study, the researchers picked out 111 college students between the ages of 17 and 30 who liked to use social media. Researchers collected their brain imaging data using MRI scans (磁共振扫描) to see the nerve system effects of short-form videos, especially in terms of structural changes and functional activity in the brain.
The results were astonishing. Students who spent more time on short-form videos had different brain structures and functions from others. There is an increase in gray matter in two brain regions, which help people make decisions, deal with information and control their emotions. This change makes the brain more sensitive to the quick pleasure of watching one video after another. That’s why it’s harder for these students to stop using short-form video apps.
Moreover, the researchers found nearly 500 genes that are related to brain changes from short-form video addiction. Interestingly, most of these genes show greater activity when people are teenagers. This shows that the teenage years are a weak period—people at this age may be more likely to get addicted to short-form videos.
31．What did the research mainly study
A．Basic structure of human brains.
B．Common behaviours of the teenagers.
C．Influences of short-form videos on our brains.
D．Popularity of short-form videos among the young.
32．What does the underlined word “astonishing” mean
A．Surprising. B．Boring. C．Common. D．Simple.
33．What does more brain sensitivity lead to
A．Easier addiction. B．Faster learning. C．Better decisions. D．Calmer emotions.
34．Why might teenagers be more easily addicted to short-form videos
A．Because they use mobile phones more frequently.
B．Because they have more free time to use apps.
C．Because some genes are more active at their age.
D．Because the brain development is largely complete.
35．Which of the following is most likely to be shown next
A．Ways for doctors to treat video addiction symptoms.
B．Methods for parents to manage their own video use time.
C．Advice for teenagers to reduce short-form video addiction.
D．Tips for schools to educate all the people on video risks.
