Many people hope to find a simple answer to whether social media damages young people’s mental health.___1___ (fortunate), the answer is not simple.Some studies report negative effects,while ___2___ (other) find positive ones, and still others find no effect at all.
In a recent study, researchers examined nearly 3,000 teenagers ___3___ (age) 15 and 16 in Ireland.They used a method that tested every possible way of looking ___4___ a set of data, and measured how time online was linked to outcomes such as self-esteem, anxiety, depression, poor sleep and diet.More than 50,000 different pathways ___5___ (assess).Overall, 64 percent suggested that more time on social media was connected with poorer health outcomes, though the effects were ___6___ (small) than many people expected.
Compared with other ___7___ (influence), such as feeling safe at school or having supportive parents, time on social media was a weak predictor of teenage wellbeing. This challenges the popular idea that social media is the main cause of rising mental health problems.A recent report in the United States found no strong evidence ___8___ social media causes widespread harm.This finding is supported by other recent reports as well.
___9___ these findings, knowing this does not mean social media is risk-free.

1.1.
A
B
C
D
解析:选Unfortunately。 Unfortunately 考查词性转换(形容词→副词)。 原文中,空位于句首,作评注性状语修饰整个句子。结合语境判断:希望找到一个简单答案:社交媒体是否损害了年轻人的心理健康,下文却说“答案并不简单”——人们想得到一个明确的“有害/无害”答复,得到的答案却并不简单,这显然是一件遗憾的事,故须取fortunate的反义语义。故填Unfortunately。
2.2.
A
B
C
D
解析:选others。others 考查代词。原文是一个三拨枚举结构:some(一些研究发现负面影响)→ 空处(另一些研究发现正面影响)→ still others(还有更多研究发现毫无影响)。空前some与空后still others形成呼应,故空处也是泛指“另外一些(研究)”,数量不确定,用复数代词others作主语。故填others。
3.3.
A
B
C
D
解析:选aged。aged 考查非谓语动词(过去分词作定语)。原文中,句子已有谓语examined,age不能以动词形式出现;teenagers与age是被动关系(“年龄为……”),故用过去分词aged作后置定语,意为“年龄在15岁和16岁的”。故填aged。
4.4.
A
B
C
D
解析:选at。at 考查介词。原文中,looking是look的动名词形式;look作“看”讲时为不及物动词,后面不能直接跟宾语,必须借助介词把动作引向对象——look at sb./sth.即“看着/审视某物”,at标明动作指向的目标。句中审视的对象是a set of data(一组数据),全句every possible way of looking at a set of data意为“审视一组数据的每一种可能方式”(of looking at...作定语修饰 way)。故填at。
5.5.
A
B
C
D
解析:选were assessed。were assessed 考查动词时态语态(一般过去时被动语态)。主语“More than 50,000 different pathways”是复数名词,与动词“assess”之间是被动关系,即“这些路径被评估”,而不是“路径自己评估”。同时,整篇文章叙述的是一项已经完成的研究,时态应使用一般过去时。因此,空格处应填一般过去时的被动语态“were assessed”。
6.6.
A
B
C
D
解析:选smaller。smaller 考查形容词比较级。句中有明显的比较级标志词“than”,说明此处需要用比较级形式。“small”是单音节形容词,其比较级为“smaller”。句意为“尽管这些影响比许多人预期的要小”,因此填“smaller”。
7.7.
A
B
C
D
解析:选influences。influences 考查名词复数。原文中,other后接可数名词复数,influence(影响因素)的复数为influences,故填influences。
8.8.
A
B
C
D
解析:选that。that 考查同位语从句连接词。“evidence”后面接了一个从句,说明“evidence”的具体内容,即“社交媒体会造成广泛伤害”。这个从句结构完整,不缺任何成分,因此用“that”引导同位语从句。“that”在从句中只起连接作用,不充当成分。注意不能用“which”或“whether”,因为这里不是在表达选择或疑问,而是在陈述事实。
9.9.
A
B
C
D
解析:选Despite。Despite 考查介词。空格后接的是名词短语“these findings”,因此需要填一个介词。根据句意,“知道这一点并不意味着社交媒体没有风险”,这与前文提到的研究发现形成让步关系,意思是“尽管有这些发现”。介词“Despite”意为“尽管”,相当于“in spite of”,符合句意。句首单词首字母要大写。
10.10.
A
B
C
D
解析:选exists。exists 考查主谓一致(一般现在时第三人称单数)。原文中,主语Dangerous content(危险内容)为不可数名词,语法上作单数看待;本句陈述的是普遍事实——网络上确实存在危险内容,应用一般现在时(前句this does not mean...is risk-free、同句those risks deserve均为一般现在时,可作印证);谓语须与单数主语保持一致,故填exist的第三人称单数形式exists。
