[分析]　此句是主从复合句。I bet是主句，其后是省略了that的宾语从句，该句本身又是一个主从复合句。you're as eager as I am to find out是主句；how many引导宾语从句。 [翻译]　相信你和我一样，迫切想知道多少人有足够的动力坚持了整整七天！ 2．My brother thought I should make full use of the time without my phone，so he took me to check out our local sports centre． [分析]　此句是并列复合句。so连接两个并列分句；第一个分句是主从复合句，My brother thought是主句，I should make full use of the time without my phone 是宾语从句；第二个分句是简单句。 [翻译]　哥哥认为我应该充分规划好没有手机的日子，因此他带我去了我们当地的体育中心。 Ⅴ．课文语法填空 Brenton High launched a fundraising campaign for new sports equipment，1．which is called the Social Media Detox．More than 100 students had been persuaded 2．to stop(stop) using social media for a whole week at the start of it． Anna lasted two days．The detox was more difficult to tolerate than she 3．had expected(expect)．But she can see how much of her time had been occupied 4．with checking her phone．She's now trying to spend 5．less (little) time online and more time picking up her hobbies． Devon lasted four days．6．Doing (do) the detox meant he and his classmate had to communicate face to face!

[1]此处是过去分词短语作后置定语，修饰each day。 [2]With the detox now finished，they've switched on⑥ their devices and they're back online．I bet⑦ you're as eager as I am to find out just how many have been motivated⑧ enough to last the full seven days! And what，[3]if anything，has been learnt from the experience? [2]此处是with复合结构在句中作状语。 [3]此处是if从句的省略结构。 Anna　17 I lasted⑨ two days．[4]The detox was more difficult to tolerate⑩ than I had expected．[5]I felt like I had lost an arm! Not eating for two days would have been easier! But on reflection⑪，I can see how much of my time had been occupied⑫ with checking my phone．I'm now trying to spend less time online and more time picking up my hobbies． [4]本句是主从复合句，than引导比较状语从句。主句是“主语＋be＋adj．(＋for sb．)＋to do”句型，tolerate与主语the detox之间是动宾关系。 [5]此处使用了虚拟语气，表示对过去情况的虚拟。 Devon　16 I lasted four days．On Monday，my classmate and I spoke about what we did at the weekend—it felt really strange not to already know what he had done．[6]We would usually have posted pictures and updated our profiles⑬．Doing the detox meant we had to talk and explain what we were doing and thinking! It made me realise the value of real contact that I had forgotten． [6]本句使用了虚拟语气，且表示与过去事实相反的情况。 Cindy　18 I managed⑭ the whole week! At first，I really felt I was missing out⑮．Then，instead of messaging my friend，I went round to⑯ her house．Without our phones，we had a proper⑰ conversation for over two hours，without being distracted⑱ by messages from other people．It felt so good！Then I decided to visit a different friend every day．By the fifth day，I wondered—was I really missing out by not constantly⑲ checking my phone to see what everyone else was up to⑳？ George　16 I did all seven days，too! [7]To be honest㉑ ，I didn't find the detox too difficult，but I did give my phone to my dad to avoid giving in! My brother thought I should make full use of the time without my phone，so he took me to check out㉒ our local sports centre．An hour's sport each day [8]left me tired out and wanting to go to bed early．The detox made me healthier! [7]本句是由but连接的并列句。第一个分句中使用了“find＋宾语＋宾补”结构，不定式短语to be honest为独立成分；第二个分句中，助动词did用于强调谓语动词，不定式短语to avoid giving in作目的状语。 [8]此处是“leave＋宾语＋宾补”结构，形容词短语tired out和动词-ing形式短语wanting to go to bed early并列作宾补。 Max　17 I'm embarrassed to say㉓ that I threw in the towel㉔ on the first day! I knew there was a party [9] happening that evening，but without access㉕ to social media I couldn't remember where it was! In the end，I turned on my phone to check，but couldn't resist having㉖ a quick look at㉗ my social media accounts㉘．What's worse㉙，I then spent so much time catching up on㉚ news，I almost missed the party! [9]此处是动词-ing形式短语作后置定语，party与happen之间是主动关系。 Moderator The detox raised a total of ￡1，632.82 for new school sports equipment! Well done，everyone who took part! After reading the posts on this forum，[10]it seems that something other than㉛ money has also been raised through the detox．Awareness㉜ of just how much we rely on㉝ social media can help us step away from㉞ it and communicate with each other better． [10]it seems that...意为“看起来……，似乎/好像……”，that引导表语从句。 社交媒体脱瘾 主持人 布伦顿高中为给购置新的体育设备筹款，举办了一项名为“社交媒体脱瘾”的活动。今天是活动的最后一天。脱瘾活动初期，我们成功说服100多名学生连续七天不得使用任何形式的社交媒体。这就意味着他们在这段时间内不能给朋友发短信，不能上传照片，不能发博客，与社交媒体相关的任何形式的活动都不行。脱离社交媒体的每一天，他们都能收到来自家人和朋友的奖励金。对此，他们很兴奋，也很紧张。但他们真的能做到吗？ 如今，脱瘾活动已结束，他们纷纷开启电子设备，重返网络。相信你和我一样，迫切想知道多少人有足够的动力坚持了整整七天！而他们，又从此次经历中学到了什么？ 安娜　17岁 我坚持了两天。社交媒体脱瘾比我预期的更加难以忍受。没了社交媒体，就像缺少一只胳膊一般。让我饿两天可能还更轻松些！但一番反思后，我也意识到平日花在看手机上的时间太多了。现在，我正试图减少上网时间，把更多精力用于重拾自己的爱好。 德文　16岁 我坚持了四天。周一，我和同学讨论了周末各自的活动——我并不知道他都做了些什么，这感觉太奇怪了。因为平时我们都会上传照片，更新各自的动态。参与这次脱瘾活动，意味着我们不得不互相交流并向对方解释自己的所做所想！这也让我意识到已经遗忘了的真正沟通的重要性。 辛迪　18岁 我坚持了整整一周！最初，我真的感觉自己错过了无数消息。但我忍住没给朋友发消息，而是直接去了她家。没有手机的我们，好好地聊了两个多小时，没有被其他人的消息干扰。这感觉真棒！接下来我决定每天去见一位不同的朋友。到第五天时我在想，当我不再经常地查看手机关注他人生活的时候，我真的错过了很多吗？ 乔治　16岁 我也坚持了整整七天！说实话，我觉得社交媒体脱瘾没那么难，但为了让自己不要半途而废，我还是把手机上交给爸爸了。哥哥认为我应该充分规划好没有手机的日子，因此他带我去了我们当地的体育中心。每天一小时的运动让我筋疲力尽，想早点上床休息。脱瘾活动使我更健康了！ 马克斯　17岁 我都不好意思说自己第一天就打了退堂鼓！脱瘾活动开始的当晚有个聚会，但如果不靠社交媒体的话，我怎么也想不起地点在哪儿！最后我还是打开手机查看了一下，结果没忍住，偷看了一眼我的社交媒体账户。更糟的是，我花了大把时间刷新动态，差点错过了本该要去的聚会！ 主持人 此次脱瘾活动总共为学校募集了1 632.82英镑，用于购置新的体育设备！每位参与者都做得很棒！看了论坛上的帖子，这次活动对人们的影响似乎远远不止通过活动筹集到的钱。脱瘾活动还让我们意识到自己对社交媒体的依赖程度，从而帮助我们摆脱它的束缚，更好地互相沟通。 1 / 11 学科网（北京）股份有限公司 $
