辨析：switch n和turn n含义侧重：switch n：着重指通过按动、拨动开关等动作来开启电器、设备等，比如 Switch n the radi by pressing this buttn.turn n：使用范围更广，不仅可用于开启电器设备，还可用于开启有流动性质的事物，像水龙头（water-tap）、煤气（gas）等，既可以指打开电灯这种电器，也可以用于打开其他能产生某种效果的事物。例如Turn n the gas t ck./Turn n the light.
4. Then she gave us a special task: t try living withut electricity fr a weekend.
try是动词，意为“尝试”
“try t d sth.”意思是 “努力去做某事；试图做某事” ，强调付出努力去达成某个目标或完成某项任务。例如 “I‘m trying t finish this reprt befre the deadline. 我正在努力在截止日期前完成这份报告。“try ding sth.”更侧重于尝试某种行为或方式，看会有什么结果或感受。比如“Try taking a different rute t wrk. Maybe yu’ll avid the traffic jam. 试试走不同的上班路线。也许你能避开交通堵塞。
5. Instead, we played vide games fr a while作连词引导时间状语从句：表示 “当…… 时候”，强调主句和从句的动作同时发生，从句中的动词必须是延续性动词。例如：While I was reading, my mther was cking. 我读书的时候，我妈妈在做饭。表示对比：意为 “然而”，连接两个并列的句子，对比两个不同的情况或动作。例如：Tm is tall while his brther is shrt.汤姆很高，然而他的弟弟很矮。作名词：意为 “一段时间”“一会儿”，常用于短语 “fr a while”一会 儿、“after a while” 过了一会儿,等中。例如： I waited fr him fr a while. 我等了他一会儿。 He sat quietly fr a mment, and after a while, he began t sing.
6. have smething in cmmn 有相同的特征have nthing in cmmn没有相同之处have much/a lt in cmmn有很多共同之处have little in cmmn几乎没有共同之处练习题：Althugh they are frm different cuntries, they _______ a lt _______ _______.
in cmmn
7. run ut 用完；耗尽。是不及物动词短语，后面不能直接接宾语。通常以物作主语，表示该物被用完、耗尽。例如Our fd is running ut. 我们的食物快用完了。The time is running ut. 时间快用完了。其同义短语有use up，及物动词短语，有被动语态，如The water has been used up. 水已经被用完了。run ut f：是及物动词短语，后面需要接宾语，通常是人作主语，表示人用完了某物。I have run ut f ink. 我把墨水用完了。He ran ut f mney last week. 他上周把钱用完了。
8. Hwever, it turned ut that it was very hard t live withut electricity.然而，事实证明，没有电是很难生活的。【详解】turn ut 表示“结果是，原来是”，使用如下 ：①turn ut+形容词（例The cake turned ut delicius.）②turn ut+不定式（例：She turned ut t be a dctr.）③turn ut + that从句（例It turned ut that they were friends.）
9. Since there wasn't any electricity, sme things in the fridge quickly went bad.因为没有电，冰箱里的一些东西很快就坏了。【详解1】g bad 表示“变质”。g 在这里表示“变得（坏的方面）”，是系动词，不能用副词修饰。例：g mad 发疯 g wrng 出问题【详解2】since 在此句中作连词，意为“由于，既然”，引导原因状语从句，语气比because弱。另外，since还可以引导时间状语从句，意为“自从...”。原因：Since yu knw the answer, tell me.既然你知道答案，告诉我。时间：I’ve lived here since I was brn.自我出生就住在这里。
