【題目】INTERVIEW:TIME OFF

I haven't much free time. I get a lot of homework so I spend most of my evenings doing homework and extra classes. I don't work much at weekends, though. I love dancing. I forget all about my problems when I dance, especially when I do ballet. I go to two classes on Saturdays. And I love cycling and swimming. Anything that is active, really.

I'm free all weekends and some weekday evenings too. I do my homework on Mondays, Wednesdays and Thursdays so I'm free on the other days. I love staying at home playing computer games and watching TV on my own or with my friends. My idea of free time heaven would be a whole weekend of my favorite programmer on TV and no parents telling me that it's unhealthy.

I have lots of free time. All the time I'm not in school is free time. Every weekend and every evening, I usually go ice skating or to the cinema with a big group of school friends. Sometimes we go to the disco in town. I like parties and meeting new people. My free-time heaven would be a birthday party for me! I would invite all my friends-about 30 or 40 of them-and we'd talk and dance till really late. I hope they'd bring presents too.

【1】Sally often________ in the evening.

A.dancesB.rides a bikeC.does her homeworkD.goes swimming

【題目】

Last week the electricity(power) in my flat went out. I had just got home from work and was happily making my tea, when suddenly I was surrounded by complete darkness. The lights had gone out, the oven had stopped working and my phone was no longer charging. My flatmates and I tried to fix it but we soon realised that we couldn't. We would have to wait for an electrician to come in the morning. This left me a whole night without any electricity. I wasn't really sure what to do. My typical evening is spent watching the TV and scrolling through social media. Tonight this wasn't possible. We weren't prepared with candles and matches. I couldn't even read a book.

So for me it was an early night. And I couldn't help but think, do we depend on electricity too much? That night, losing our electricity felt like losing a basic necessity-as basic as running water. But really , electricity is a luxury（奢侈）that we've grown to take for granted. I use electricity all the time, even when it's not really necessary. I use it to put the TV on in the background even when I'm not really watching it. I use it to check my phone when I have to wait for even just a minute, for example when waiting for friends. And as I'm writing this, I have my lights on, even in the middle of the day when I don't really need them.

Our over-use of electricity is a big problem. It contributes to something that we really should be worried about. It is harming our environment and we need to do what we can to stop it. Not only that, but if we continue to use the same large amount of energy we will soon run out.

How would we survive in a world without electricity? Our daily lives revolve around it. We wouldn't be able to function. Yet we know that, one day, we will run out. So, shouldn't we start preparing for it now? I know for sure that I could cut down on my use of electricity. And if everyone does the same, we can make a big difference.

【1】The writer ___ after the electricity went out.

A.found someone to fix it with his flatmatesB.bought some candles and matches

C.could do nothing but wait for an electricianD.tried to find out why the lights went out

【2】The writer thinks that____________

A.he makes full use of electricity

B.electricity is much more important than it was

C.electricity should not be as necessary as it has now become

D.the over-use of electricity leads to global warming

【3】The writer's main purpose in writing this passage is___________.

A.to list some ways to save energy

B.to explain reasons for global warming

C.to share his personal experience of using electricity.

D.to call on us to protect our environment by using less electricity
