Reading strategy
Making predictions
You can make predictions by looking at the title, the writer's name and the beginning of each paragraph. Before you read the story, take a quick look at the title “A switch-off weekend”. Notice that the writer is “Daisy from Grade 7”, and read the first sentence of each paragraph and guess what happens in the story.
你可以通过看标题、作者的名字和每一段的开头来做预测。在阅读文章之前，先快速浏览标题“一个没有电的周末”。注意作者是“七年级的黛茜”，阅读每一段的第一句话。你能够猜到故事里发生了什么吗？
Last week, our science teacher, Mrs Brown, taught us about electricity
and how important it is. Then she gave us a special task: to try living
without electricity for a weekend. Our family thought it sounded interesting, so we decided to do it together.
However, it turned out that it was very hard to live without electricity. After it got dark, my little brother Benny and I could only read and write by candlelight. We usually watch a movie together on Friday nights, but the TV doesn't work without electricity. Instead, we played video games for a while, but then our tablet ran out of battery. “What about tomorrow ” we thought.
A switch-off weekend
Read the story.
by Daisy from Grade 7
Since there wasn't any electricity, some things in the fridge quickly
went bad. When we woke up on Saturday morning, we discovered
that we couldn't eat our breakfast cereal (n. 麦片) —we didn't have any milk or yogurt! By noon, it got really hot inside our apartment, but we couldn't turn on the air conditioner. Even worse, most household tasks became very difficult without electricity. For example, we had to wash all our clothes by hand, and this took us a lot of time.
However, there were also nice things about living without electricity. On Sunday, we went on a bike trip and visited my grandparents in the countryside. We enjoyed a picnic in their garden, and we also played chess and painted pictures together. At night, we sat under the stars and listened to my grandad's stories.
This was a really interesting experience, but I cannot imagine living without electricity for more than a few days.
Read and underline the phrases then translate them into Chinese.

Electricity is extremely important. When living without it for a weekend, daily activities were severely disrupted. We couldn't watch TV on Friday nights, and our tablet ran out of battery quickly.
Without electricity, food in the fridge spoiled, and we couldn't enjoy our regular breakfast.
We couldn't use the air conditioner to cool the apartment on a hot day. Even basic household chores like washing clothes became much more time - consuming as we had to do them by hand. Overall, life becomes far more challenging and inconvenient without electricity.

4. Then she gave us a special task: to try living without electricity for a weekend.
try是动词，意为“尝试”
“try to do 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 to finish this report before the deadline. 我正在努力在截止日期前完成这份报告。“try doing 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 route to work. Maybe you’ll avoid the traffic jam. 试试走不同的上班路线。也许你能避开交通堵塞。
短语 核心区别 例句
try to do sth. 努力/试图做某事（强调付出努力，结果可能成功或失败）。 She tried to finish her homework early.
她努力想早点完成作业。
try doing sth. 尝试做某事（强调用某种方法试试看效果，或建议某种解决方案）。 Try adding sugar if the coffee is bitter. 如果咖啡苦，试着加点糖。
try one’s best to do sth. 尽某人最大努力做某事 I’ll try my best to finish the task on time.
我会尽力按时完成任务的。
5. Instead, we played video games for 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 mother was cooking.
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：
Tom is tall while his brother is short.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 “for a while”一会
儿、“after a while” 过了一会儿,等中。例如：
I waited for him for a while. 我等了他一会儿。
He sat quietly for a moment, and after a while, he began to sing.
6. have something in common 有相同的特征
have nothing in common没有相同之处
have much/a lot in common有很多共同之处
have little in common几乎没有共同之处
练习题：
Although they are from different countries, they _______ a lot _______ _______.
have
in common
7. run out 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 food is running out. 我们的食物快用完了。
The time is running out. 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 out of：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 out of ink. 我把墨水用完了。
He ran out of money last week. 他上周把钱用完了。
8. However, it turned out that it was very hard to live without electricity.然而，事实证明，没有电是很难生活的。
【详解】turn out 表示“结果是，原来是”，使用如下 ：
①turn out+形容词（例The cake turned out delicious.）
②turn out+不定式（例：She turned out to be a doctor.）
③turn out + that从句（例It turned out that they were friends.）
9. Since there wasn't any electricity, some 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】go bad 表示“变质”。go 在这里表示“变得（坏的方面）”，是系动词，不能用副词修饰。
例：go mad 发疯 go wrong 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 you know the answer, tell me.既然你知道答案，告诉我。
时间：I’ve lived here since I was born.自我出生就住在这里。
