SOCIAL MEDIA DETOX①

Moderator②

Today marks the last day of the Social Media Detox，Brenton High's fundraising③ campaign for new sports equipment.At the start of the detox，over 100 students had been persuaded to stop④ using social media，in ANY form，for seven days.This meant no messaging⑤ friends，no posting photos，no blogging—nothing.They had been promised money by family and friends for each day [1]spent without using social media．They were excited.They were nervous.But could they do it?

[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。

I lasted⑨ two days.[4]The detox was more difficult to tolerate⑩than 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。

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。此处可以理解为省略了从句“if we hadn't taken part in the campaign”。

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？

I did㉑ all seven days，too! [7]To be honest㉒，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 out㉓ 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是独立成分；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和现在分词短语wanting to go to bed early并列作宾补。

I'm embarrassed to say㉔ that I threw in the towel㉕on the first day! I knew there was a party [9]happening that evening ，but without access㉖ to social media I couldn't remember where it was！In the end，I turned on my phone to check，but couldn't resist having㉗ a quick look at㉘ my social media accounts㉙.What's worse㉚，I then spent so much time catching up on㉛ news，I almost missed the party!

[9]此处是v.-ing短语作后置定语，party与happen之间是主谓关系。

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 than㉜ money has also been raised through the detox．Awareness㉝of just how much we rely on㉞ social media can help us step away from㉟ 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。
