Now, a teenager with 41 same problems might write them in a blog. So, what makes them different? The biggest 42 (different) is that a blog is much more public. Usually, a teenager hides his diary and treats it as something full of 43 (secret). A blog has both good and bad points. The biggest problem is that anyone can 44 (read) your blog. If you are 45 (happy) with a friend and write something bad about him in your diary, he may never know. However, 46 you do this online, that friend might read it and get angry. So we must be careful 47 what we write. Of course, blogs have good points too. People write in blogs knowing friends will read them. If you feel sad and write in 48 (you) diary, nobody may know. But if you write the same in your blog, friends may 49 (quick) offer help. Blogs help people stay in close connection and learn about friends’ lives.

These days it’s common for you to get a pop-up. It lets you 51 (put) the app in “teen mode (模式)” every time you begin to use apps. A lot of apps, especially video apps, have added this feature (功能) to protect teenagers. It’s said that it will bring teenagers 52 (good) experiences than before and make sure they’re using the apps in a healthier way. For example, some short video apps have the feature to stop teenagers from 53 (watch) videos for long and with the feature, they might only be allowed to watch for 40 minutes. The videos that teenagers can watch are ensured to be safe and even 54 (education). There are no advertisements and teenagers cannot pay any money 55 the videos. In QQ’s teen mode, teenagers can only talk to people on their contact lists. 56 (they) chat records show pinyin, which is useful for primary school students. However, the teen mode does not work for all apps, according to 57 recent report. There aren’t any 58 (different) between the teen mode and the normal mode in some apps. And in some video apps, the teen mode won’t start 59 users watch videos for 40 minutes. But users can get past it 60 clicking “I know” and continue watching. Though you can learn a lot from short videos, it’s necessary to control the time. 【答案】 51．put 52．better 53．watching 54．educational 55．for 56．Their 57．a 58．differences 59．until 60．by 【导语】本文主要介绍了现在很多应用程序都添加了“青少年模式”，以保护青少年，但并不是所有应用程序的“青少年模式”都有效。 51．句意：它让你每次开始使用应用程序时，将应用程序设置为“青少年模式”。let sb. do sth.“让某人做某事”，此处用省略to的动词不定式作宾语补足语。所以填put。 52．句意：据说它将给青少年带来比以前更好的体验，并确保他们以更健康的方式使用应用程序。根据“than before”可知，此处用形容词good的比较级better“更好的”作定语，修饰名词experiences。 53．句意：例如，一些短视频应用程序具有阻止青少年长时间观看视频的功能，有了这个功能，他们可能只被允许观看40分钟。stop sb. from doing sth.“阻止某人做某事”，此处用动名词watching作宾语。 54．句意：青少年可以观看的视频确保是安全的，甚至是有教育意义的。此处作表语，用形容词educational“有教育意义的”与safe并列。 55．句意：没有广告，青少年也不能为视频支付任何费用。pay...for...“为……支付……”，固定短语。 56．句意：他们的聊天记录显示拼音，这对小学生很有用。此处作定语修饰chat records，用形容词性物主代词their“他们的”，句首首字母大写。 57．句意：然而，根据最近的一份报告，青少年模式并不适用于所有应用程序。report“报告”，此处泛指一份报告，且recent以辅音音素开头，用不定冠词a。 58．句意：在一些应用程序中，青少年模式和普通模式没有任何区别。different“不同的”，形容词；any后跟可数名词复数或不可数名词，difference“不同之处”，可数名词，此处用复数形式differences。 59．句意：在一些视频应用程序中，青少年模式在用户观看视频40分钟后才会启动。根据“the teen mode won’t start...users watch videos for 40 minutes”可知，此处指青少年模式在用户观看视频40分钟后才会启动，not...until...“直到……才……”。 60．句意：但用户可以通过点击“我知道”来跳过它，继续观看。根据“get past it...clicking ‘I know’”可知，此处指通过点击“我知道”来跳过它，by“通过”，介词。 $ 班级 姓名 学号 分数 Unit 10 World in the
