on a desert island?
on 23rd April by
Steve&&&&&&&&&&&&&&&&&&
Posts 1 – 7 of 42
everyone. What would you miss most and least if you were stuck on a desert
island? For me, it would be the changing seasons in New England. I guess this
will sound stupid but I’d probably miss the rain, too. I wouldn’t miss
getting up at six every day to go to work, though! What about you?
question. Steve, I think I’d miss different types of bread, and shopping at
the supermarket. I’d miss the food most. What would I miss least? My mobile
phone---I’d like to be completely quiet --- at least for a little while
would miss the company of people because I know I’d like to have someone to
share experiences with. I’d go mad on my own. And I sure wouldn’t miss junk
mail(垃圾邮件) --- I hate coming home every
evening and a pile of junk mail in my post box.
I would miss Manga cartoon, the internet and Japanese food, like sushi. I’d
also miss TV shows and shopping for clothes… In fact, I’d miss everything.
would miss my daily newspaper and listening to the news on TV and radio. I’d
feel very cut off if I didn’t know what was happening in the world. What I’d
miss least would be traffic jams in the city, particularly my journey to
hasn’t anyone mentioned their family? I’d be lost without my husband and two
kids. They’re the most important for me. And I can’t get started in the
morning without a cup of black coffee. I wouldn’t miss doing the
housework!&
would have to be music. I couldn’t live without my music. I wouldn’t miss
going to school at all or doing homework!
Who would miss his or her family most?
A. Jaime&&&&&& B. Jayne&&&& &&&&C. Miko&&& &&&&&&D. Paola.
Which of the following people would feel most uncomfortable without the news media?
A. Steve.& &&&&&B. Jaime&& &&&&&&&C. Roger.&&&& &&&D. Tomas

I cheated on a unit test in math class this morning during second period with Mr. Burke. Afterward, I was too sick to eat lunch just thinking about it. I came straight home from school, went to my room, and lay on the floor trying to decide whether it would be better to run away from home now or after supper. Mostly I wished I was dead. It wasn't even an accident that I cheated. Yesterday Mr. Burke announced there'd be a unit test and anyone who didn't pass would have to come to school on Saturday, most particularly me, since I didn't pass the last unit test. I did plan to study just to prove to him that I'm plenty smart—which I am mostly—except in math.Anyway, I got my desk ready to study on . Just when I was ready to work, Nicho came into my room with our new rabbit and it jumped on my desk and knocked the flashcards all over the floor. What a mess! Nicho and I finally took the rabbit outside but then Philip came to my room and also Marty from next door and before long it was dinner. After dinner my father said I could watch a special on television if I'd done all my homework. Of course I said I had. That was the beginning. I felt terrible telling my father a lie about the homework.It was nine o'clock when I got up to my room and that was too late to study for the unit test so I lay in my bed with the light off and decided what I would do the next day when I was in Mr. Burke's math class not knowing the 8- and 9-times tables. So, you see, the cheating was planned after all. The next day, I'd go into class as usual, acting like things were going just great. I'd sit down next to Stanley Plummer—he is so smart in math it makes you sick—and from time to time, I'd glance over at his paper to copy the answers. Lying on the floor of my room, I begin to think that probably I've been bad all along. It just took this math test to clinch it. I'll probably never tell the truth again. I tell my mother I'm sick when she calls me to come down for dinner. She doesn't believe me, but puts me to bed anyhow. I lie there in the early winter darkness wondering what terrible thing I'll be doing next when my father comes in and sits down on my bed. "What's the matter?" he asks. "I've got a stomachache," I say. Luckily, it's too dark to see his face. "Is that all?" "Yeah." "Mommy says you've been in your room since school." "I was sick there too," I say. "She thinks something happened today and you're upset." That's the thing that really drives me crazy about my mother. She knows things sitting inside my head the same as if I was turned inside out. "Well," my father says. I can tell he doesn't believe me. "My stomach is feeling sort of upset." I hedge. "Okay," he says and he pats my leg and gets up. Just as he shuts the door to my room I call out to him in a voice I don't even recognize as my own. "How come?" he calls back not surprised or anything. So I tell him I cheated on this math test. To tell the truth, I'm pretty much surprised at myself. I didn't plan to tell him anything.He doesn't say anything at first and that just about kills me. I'd be fine if he'd spank me or something. And then he says I'll have to call Mr. Burke. It's not what I had in mind. "Now?" I ask surprised. "Now," he says. He turns on the light and pulls off my covers. "I'm not going to," I say. But I do it. I call Mr. Burke, and I tell him exactly what happened, even that I decided to cheat the night before the test. He says I'll come on Saturday to take another test, which is okay with me, and I thank him a whole lot for being understanding and all."Today I thought I was turning into a criminal," I tell my father when he turns out my light. Sometimes my father kisses me good night and sometimes he doesn't. I never know. But tonight he does.【小题1】After the author cheated on the math test, he felt ____________.A.frightened because he might be caughtB.excited that he had succeededC.pleased that nobody knew itD.unhappy because he had done something wrong【小题2】By “It wasn't even an accident that I cheated”, the author means that ________.A.he had planned not to study before the testB.he decided to cheat when he knew there was going to be a testC.he decided to cheat after he had wasted the whole eveningD.he had planned to cheat with Plummer before the test【小题3】The author’ mother often drives him crazy because _____-.A.She really knows what he is thinkingB.she was very strict with himC.she doesn’t believe himD.she asks him to come down for dinner【小题4】After he was informed of what he had done, the father _______.A.scolded the author severelyB.didn’t say anything and leftC.called Mr. Burke immediatelyD.let the author make a call to Mr. Burke【小题5】The author’s father kissed the author good night because ________-.A.he had done something unusualB.he promised to study math harderC.he was willing to take a make-up testD.he realized his mistake and had the courage to admit it

Last year, my boyfriend suggested that I
should run the London marathon(马拉松), and I laughed. He laughed too, but he laughed too long and too
loud. That made me think. I realized that he didn't believe that I could do it.
That made me angry, and determined, Now he knows that I can!
Training wasn't easy, but I kept going. I
didn't need special training but I did need to buy very good shoes. Each day, I
went a little further. By the end of three months, I was running five days a

I used to come home, have a shower and eat my breakfast. I felt wonderful!
On the day of the race in London, I lined
up with about 30,000 other runners. The faster runners were at the front, while
slower runners like me were placed further back. In that way, the professional
runners and club runners were not slowed down by the amateurs(业余爱好者).
At first, there were so many runners close
together that we were almost falling over each other.& We could only run
very slowly but that was a good thing because it meant that we didn't rush off
too quickly. Gradually the runners spread out and there was more space. There
were thousands of people watching us along the route and they cheered and
clapped everyone, even the slowest runner. It was wonderful!
For the first 10 km I felt very happy and
my legs felt very comfortable. However, at 15 km I got a pain in my side and
running became difficult, but I kept going and the pain disappeared. At the 30
km mark, I felt extremely tired, and wanted to stop, but I kept on going. I

me feel lighter and faster and it seemed as if my legs flew over the last few
kilometers. I passed hundreds of slower runners, some of whom had passed me
earlier, and I felt wonderful! AS I came round the last bend(弯道)and saw the finishing line, I
could see three runners ahead of me. I raced past all of them to finish the
race in just under four hours. The winner had completed the race in 2 hours and
10 minutes, but I didn't care! I had run 42 km and completed my first marathon!

when和while引导时间状语从句的区别及专项练习题
When,While,As引导时间状语从句的区别
when,while,as显然都可以引导时间状语从句,但用法区别非常大。
一、when可以和延续性动词连用,也可以和短暂性动词连用;而while和as只能和延续性动词连用。
① Why do you want a new job when you’ve got such a good one already?(get为短暂性动词)你已经找到如此好的工作,为何还想再找新的?
②Sorry,I was out when you called me.(call为短暂性动词)对不起,你打电话时我刚好外出了。
③Strike while the iron is hot.(is为延续性动词,表示一种持续的状态)趁热打铁。
④ The students took notes as they listened.(listen为延续性动词)学生们边听课边做笔记。
二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while和as从句的谓语动作必须是和主句谓语动作同时发生。
1.从句动作在主句动作前发生,只用 when。
①When he had finished his homework,he took a short rest.(finished先发生)当他完成作业后,他休息了一会儿。
②When I got to the airport,the guests had left.(got to后发生)当我赶到飞机场时,客人们已经离开了。
2.从句动作和主句动作同时发生,且从句动作为延续性动词时,when,while,as都可使用。
①When /While /As we were dancing,a stranger came in.(dance为延续性动词)当我们跳舞时,一位陌生人走了进来。
②When /While /As she was making a phone call,I was writing a letter.(make为延续性动词)当她在打电话时,我正在写信。
3.当主句、从句动作同时进行,从句动作的时间概念淡化,而主要表示主句动作发生的背景或条件时,只能用 as。这时,as常表示“随着„„”;“一边„„,一边„„”之意。
① As the time went on,the weather got worse.(as表示“随着„„”之意)
② The atmosphere gets thinner and thinner as the height increases.随着高度的增加,大气越来越稀薄。
③As years go by,China is getting stronger and richer.随着时间一年一年过去,中国变得越来越富强了。
④The little girls sang as they went.小姑娘们一边走,一边唱。
⑤The sad mother sat on the roadside,shouting as she was crying.伤心的妈妈坐在路边,边哭边叫。
4.在将来时从句中,常用when,且从句须用一般时代替将来时。
①You shall borrow the book when I have finished reading it.在我读完这本书后,你可以借阅。
②When the manager comes here for a visit next week,Ill talk with him about this.下周,经理来这参观时,我会和他谈谈此事。
三、when用于表示“一„„就„„”的句型中(指过去的事情)。
sb.had hardly(=scarcely) done sth.when...=Hardly / Scarcely had sb.done sth.when...
①I had hardly /scarcely closed my eyes when someone knocked at the door.=Hardly / Scarcely had I closed my eyes when someone knocked at the door.我刚一闭上眼,就有人在敲门了。
②I had hardly /scarcely entered my room when the telephone rang.=Hardly /Scarcely had I entered my room when the telephone rang.我刚一走进房门,电话就响了。
