“Cenila! Run!” I heard Mary scream. I ran as they ran. What was going on, I had no idea why I was running with them. And I have no idea why they were running. Where am I? I looked around and saw a big screen at the front and rows and rows at the back. I am at a cinema. How did I get here? I asked myself. “How come Cencila is here? I thought she flew away to another city. “Stop running and tell me what’s going on!” I shouted but they didn't seem to hear me. They just carried on running.“Stop it!” I hollered. But they didn't even take a look at me and the carried on running.“Fine, if you don't stop, I will.” I muttered under my breathe. I forced myself to try and stop my feet from moving but I couldn't control my legs. I decided to let it be. I saw David and Sophie running after them. David had a knife in his hand.Mary and Cencila rushed into one of the personal rooms, David and Sophie followed tightly after them. The door of the room closed but my legs still seemed to be moving. I am running towards the closed door without any control of my legs. I was ready for a big CRUSH on the door. But when I reached the door I sank trough with no feeling of the door. And moments after I was inside the room. I looked back, the door was still closed and it never opened, so how did I get in?There’s no time to think about these stuff because my eyes are fixed on David and them. My legs caught up with David. When I looked at him. He had the evil smile on his face and this wasn't the first time. I had always had that smile on his face. Sophie ran beside david. I looked once again at david’s face and the knife in his hand, I realized he was going to kill Cencila and Mary with it. So that's why they were running. Sweat poured from my forehead as I thought of this, I’ve got to save mummy. Where are they? Maybe they got out safely or maybe they are stuck in the corner of this room.David opened the door to another secret place and slammed the door shut. I was running so fast that I didn't have time to open the door again. I was ready for a BANG on the door which would smash my head open but again, I sank through the door. I’ve entered a tunnel which I’ve never seen before. Where are Cencila and Mary? I wondered. But before long, I saw them infront of two doors. Cencila entered one of them and Mary entered the other. David and sophie entered the one that Cencila entered! OH NO, they are after mummy!I wanted to run faster but as I said I had no control of my legs so I couldn’t. When I came close to the two doors I saw a sign.It said: These are the two exit to choose from, one of them is the one you’ll get out safe with and the other one is the one you’ll die in!You make the choice!Ok, which one could be the real exit? I looked uneasily at the door identical doors. I’ll just enter the one Cencila did. This time I didn't even try to open the door I just ran through. I was far behind David, I need to catch up or I’ll never be able to save mummy. I thought. My legs granted my wish. I seemed to be running faster. Before long, I caught up with David. Then I saw something that made my eye pop out! Cencila was standing there, trembling with fear. Because behind her was a bricked grey wall- no exit! This must be the fake one. David and Sophie was coming closer to Cencila. That pair of evil eyes…. That sharp knife…… that grey wall with no exit……. Made it seem everything turned into a nightmare. They were coming closer, closer and closer. As David was about to stab Cencila with the knife I reached out my hands to grab the knife out of David’s hands but my hands were like a bunch of clouds. They just simply sank through david’s hands. Am I a ghost? Why can no one hear me, no one feel me like I don't exist? There was no time to think about that. I wasn't running anymore, don't know why. I stood there as still as a statue as I saw David’s knife cut through Cencila, I heard a heart breaking scream. Hot tears poured down my face……

Chapter5“Me?” the girl turned around and looked at me. “I’m Elizabeth- your stepsister.” She rolled her eyes “Didn’t mummy tell you about me?”I smiled at her. “No, she must have forgotten.”“She always forgets, she has a bad memory.” Elizabeth said lowing her voice. I laughed. “Nice thing to say about your mother!”The door pushed open and Sophie walked in with my chocolate milk.“Are you talking about me?” She asked smiling as she handed me the chocolate milk.“Yeah, we were saying that you have a…” Said Elizabeth naughtily but I covered her mouth just in time.“Errr…we were just saying what a wonderful mother you are.” I prompted.“Okay, okay.” Sophie conceded.“Annie, drink your milk and go to bed, Elizabeth follow me, I need to have a word with you.” Sophie walked out of the room and Elizabeth followed. I drank my milk and turned off the light. I went to bed but couldn’t sleep. Something doesn't feel right about Sophie. Maybe it’s because she is too nice and I’ve never thought a stepmother will be so nice to a child that's not even hers.I could hear Sophie and Elizabeth whispering outside of the door. I couldn’t really hear what they said but I bet Sophie is teaching Elizabeth how to behave now that she is part of this family.I’ve got a nice family now. With a wonderful stepmother and a wonderful stepsister but let’s not try to think in the negative side- my dad who cheats on his wife he cheated on mum, and Sophie will be no exception. I could imagine David going off with other girlfriends and leaving Sophie, Elizabeth and me home. But I don't care, I don't need my dad. Mum told me to be independent and I will. Sophie, Elizabeth and I are going to have the time of our life together at home- with out David, that I know for sure. Should I tell Sophie How David really is, and how he cheats on all his wife? No, I won’t. I’ll make sure Sophie finds out herself because then she’ll react worse. I thought.It’s not that I want Sophie feel bad, it’s that I don't want David to get away of doing all this, to me and to Cenila- to sophie and Elizabeth later on. But how am I going to stop david from cheating on his wives? How? Then I remembered what Cenila always says. “Never give up trying, in the end you will make it.” I closed my eyes. Cencila’s face formed in my mind. How I wish you were here! Why did you leave me with out saying goodbye? I thought. I would never forget her smile, and mostly I would never forget about her no matter how nice Sophie is.No one can ever replace her in this world and definitely not in other worlds if there are. I was deep in thoughts and soon after I fell asleep.

首先第一个问题,这句话是与现在事实相反的虚拟语气.
其次,你说的“在这篇课文中,描述的是过去的事情”,课文的时态是过去时没错,但仔细分析这个句子,应该理解为“在当时那个条件下,海底隧道应该还没有建成时,提出的一种设想”.相比于“当时”,确实可认为是将来时.
再次,改为陈述句：Tall chimneys were bulit above sea-level,so the tunnel was well-ventilated.
最后,此为if引导的条件句,不算虚拟语气用法.”从句一般过去式,主句过去将来式“

如果火车驶进隧道,它后面就会带进新鲜空气来.
在……后面,自然是behind
请及时采纳,多谢!

等等,看我的回答.
①一列火车刚才穿过了隧道.
A train ( went/ran/passed ) ( through )the tunnel just now.
the tunnel 强调【从某空间范围内穿过】,要用介词through.
②星期天你想和我一起去购物吗?
Would you like to (do ) (some )( shopping )with me on Sunday?
给三个空用 do some shopping;两个空用 go shopping.
③他在度假的时候去看望了他的叔叔.
When he was ( on)(holiday ),he visited his uncle.
be on holiday/holidays 在度假,固定短语.
④你对到太空旅行感兴趣吗?
Are you 【interested】 in the (travel )( in )(space)?
“太空旅行”强调“长途、远程旅行”,用travel.
⑤在这条街上我们到处可以看到国旗.
We can see the(national)(flag)everywhere on this street.

你好,
1,选D ferry
n.渡船；渡口；摆渡；用船渡运
vt.航海；渡运；（乘渡船）渡过（河等）
vi.摆渡
by ferry表示乘渡船
2,选C,can be true表示会是真的,这是一种习惯表达
3,A,foods这时候是可数的.

subways tunnels highways piers photos harbours factories bridges buildings these
楼上 photo 的复数写错了应该加 S .其他的对、

B

穿过隧道的英语 drive（ through）the tunnel
through：穿过里面
across：从表面上穿过
多谢!

句子错了,back and forth直接加名词是什么意思?应该是back and forth in the happy tunnel in time吧?而且句首应该还有个表动作的动词像穿梭、翻滚什么的吧?然后整个句意就是“及时在幸福隧道里来回...（括号里是动词的意思）”

“The pop corn machine broke down so we went out of the cinema to get some. But there weren’t any. So we went to the big supermarket but it was closed.” Julia lied.Sophie didn't say anything.We sat down and another row. The movie finished.“Why are we still sitting here?” I asked.“I was worried about you guys. I thought you were kidnapped or something. So I called your father. He is coming in ten minutes.” She looked at her watch. I could tell that was a lie.We thought for ten minutes. It was boring. Julia and I prepared for a long fast run.Sophie got a phone call, it was a quite shout one.“Hi……so you arrived…… Ok stay there, wait for the right time…… I’ll call you……bye.”I could wait no longer, it was time to break the bubble.“Sophie,” I said “You don't have to lie to me anymore, I know everything about you’re plan. Julia told me”I thought she was going to pretend to be innocent. But she didn’t, she was prepared for this, she wasn’t surprised.She stared at me with her dead fishy eyes. She had the most evil smile worn on her face. She slowly picked up her mobile and spoke to it.“Now!” She said coldly. “She found out.”Sophie turned to Julia, fixing her icy eyes on her “Kiss your friend good bye,” Sophie said grimly. “Because you are never going to see her again.” Sophie’s eyes shone in the darkness.That call was obviously for David, because seconds after David burst in with a knife in his hand.“Run!” I cried.Julia and I ran for the staff room. We had prepared for this long run.They followed tightly after. We ran to the end of the room. We knocked on the walls. The walls opened. We ran in.We were quite fast runners. We have even won first and second places at the running competition in my school.We left them far behind.We were at the end of the tunnel, with too doors, we went into the left one.We made the way out!!!!!!Sophie and David got caught by the police.We jumped on the green grass field. I have never felt this happy before.Julia and I have gone through this adventure together. And our friendship became deeper and deeper.Deep…….Deep……. down to the earth……May Cencila’s soul rest in peace……

我的理解就是这只是用来标示这个tunnel用的,没有其他的意义了.

单数形式：
subway、tunnel、harbour、ferry pier、bridge、highway、building、factory
复数形式：
subways、tunnels、harbours、ferry piers、bridges、highways、buildings、factories
【额外补充】
通常我们在名次后面加S就可以了 但是一些特殊的单词例如Factory 就要把y变i再加es
再例如bus我们就要在后面加es 另外还有很多就不一一举例了

Chapter 8I finished off the last bit of my bread.“I think it’s about time for you to go to school.” Sophie noted, looking at her watch.I picked up my bag and grabbed on to the keys.“Bye Sophie, bye Elizabeth.” I called. “Oh wait, where shall I meet you for the movie?” I asked.“Umm, just outside the cinema.” Said Sophie.“Ok bye.” I tied my shoelaces and left.I jumps off the footsteps joyfully with the thought I was going to see my favorite movie again. My heart cooled down soon after.My hair was blown to my face by a cool gust of wind. Seconds after the whole street was drowned by the reddish leaves. Then I realized it was early autumn. My mind was dragged back to one point of my memory. It was when my only sister died. That day was in early autumn, leaves were flying all over the streets. My sister, Cencila, Julia and I were at the hospital. The windows were opened, my sister was lying on the bed, smiling to me. She had a illness which nothing can help her. Then all of a sudden a strong gust of wind flew in the room which made her hair covered her whole face. When the wind left, I carefully lifted her hair from her face, which was when I screamed. I found her totally pale, motionless and dead. The wind had killed her. What hurted me the most was that david didn’t even bother to come to the hospital for her last breath. Instead of being sad, he was happily going on a date with his ‘girlfriend number 11’ (Which means he has many) What a father!“Why do I always have to think about the sad things?” I asked my self a question that I couldn't answer.I smiled, or maybe just to make my self better. “Think of the bright side” I said quietly, which was when I got to Julia’s house.“I hope she isn’t late again.” I went over and rang her bell vigorously. The door opened and I saw the same pale and skinny woman.“Hi Mary.” I said tardily when I saw the expression on her face.“Hi Annie,” She said weakly. “Sweetie, are you alright?”I looked at her with a puzzled look. “What do you mean, why wouldn’t I be?” She turned around to hide from my question.“Oh well, you are here to get Julia, I’ll get her for you.” She said vaguely. “No, wait!” I pulled her back. “Give me an explaination first.” I said sternly.“Oh it’s nothing, I just asked because I …” she stopped and then continued. “I just thought you wouldn't like to have a stepmother.”At the mention of my stepmother my whole face brightened up.“Oh god! Are you kidding me?” I burst out. “She is just wonderful.” I praised.“That's good, take good care.” Mary said as if she was never going to see me again. Julia had just scarcely finished brushing her teeth.“Come on!” I rushed. “We don't want to be late for school do we?”“ Okay, okay I am coming.” Julia gave Mary a quick kiss and came out.We walked towards the school together. Then there was a strained silence.“Julia, don't you think your mum is acting a bit weird these days?” I asked at last. She gave me a plain and innocent look.“No, not really. That’s how she act normally.” She replied.“Did she tell you anything unusual?” I decided to ask again but the answered disappointed me again.“ No, not really.” She said vaguely.She is hiding something from me, whatever it is, I must find out!

第一个和后两个的字母数量不同 后两个虽然字母数量相同 但是字母样子不同 还有一点我敢肯定他们仨的意思也不是完全相同 我回答对不对?

如果就这句话,意思是,如今,一条贯穿大山的隧道造好了.now和that不是词组,that引导后面的内容,起到一个关系词的作用.

I woke up in my bed. I could feel my eyes sore from crying. It was all a nightmare. The nightmare seemed so real. I was scared. I was lonely. I was helpless. When I think of that terrifying scene, a cold shiver ran down my spine. I was breathing hard.“It’s ok, everything is just fine. It was all a nightmare which is totally fake.” I comforted myself.I got out of bed and slipped into my school uniform out of my pajamas. I stood in front of the mirror and brushed my black hair. I stared at the empty space, mum’s face formed in the mirror. “Get revenge for mommy.” She said softly, her image disappeared seconds after. Was that real or was that just my imagination? Just my imagination because it was just a dream, it can’t be real. I decided to think no more about it. I walked slowly to the dinning room, deep in thoughts. If it was just a dream, why did it feel so real?Soon I realized I wasn't buttering the bread. I was buttering my fingers. EUUUU! Yuck! I went over to the sink and washed my hands. Through the water I saw Cencila’s face again.Then I heard the same sentence “Get revenge for mummy…… Get revenge for mummy…….”I felt totally spooked. What’s going on? I must be missing my mum like crazy to imagine all these things. I turned off the tap and eventually Cencila’s image disappeared again. I slowly sat back down at the table, I continued having my breakfast. Ignore my imagination, just ignore it. It will soon be over. I thought. I don't know what happened but something just drove me to the mirror. I caught my reflection in the full length mirror. Something happened again which didn't surprise me much. Cencila’s face appeared again in the mirror. But this time she didn't say anything that I thought so would.“Be strong, I’ll see you very soon even I hope that I won’t.” She said softly, looking hopelessly at me. This got to be real, it cant be my imagination again!“Why don't you want to see me?” I asked angrily. I feel like I was a fool.Her sad eyes told me something. “I wish I could tell you but I really can’t.” She replied.“Why can’t you tell me?” I demanded.Just then I heard some footsteps. I turned around, there was Sophie, David and Elizabeth. “Who are you talking to?” Sophie asked laughing.“Errr….” I’ll tell them what happened I decided. “I know this sound crazy but I saw mummy in the mirror and she was talking to me.” I explained.Sophie wasn't laughing anymore.“She what? What did she say to you?” I couldn't ignore the hideous expression on her face.Sophie, realizing she had just scared the hell out of me, softened her voice, gave me a plain smile.“ Oh it couldn’t be, you’re just imagining everything.”Yes, I really hope you are right.They started laughing even more.“You are nuts, Annie.” Said Elizabeth, laughing. “We saw you talking to you own reflection.”“But….” I turned around so I could so them that Cencila was there but all I saw in the mirror was my own reflection, no image of Cencila. When they saw the puzzled look on my face they started laughing again.“Come one everyone, let have breakfast, we don't want to spend our whole day here laughing our heads off, do we?” Sophie insisted.We all walked in to the dinning room and had a seat.“Could you please pass me the butter?” Elizabeth asked politely. She was sitting at the end of the table and there was no way that she could have been able to reach it.I reached out my hands to pass her the butter but my sleeve got caught on the glass, I accidently knocked it over. The juice in it splashed and it got on Sophie’s beautiful dress.David stood up. “Next time, becareful!” David shouted angrily. Sophie pulled him back down the table. “It’s ok, just a little juice. It will go away in the washing machine.” Sophie said kindly.“I have to go to work now.” David announced loudly. “And don't forget we have some very important things to do today.”Sophie grinned. “Don't worry, I’ll take very good care of the kids.”Wow! GOOD CARE. How terribly nice of her. I thought, but except that I never knew what the ‘good care’ really meant.

解,设隧道长x米,则(x+60)/（4*60）m/s=120km/h=100/3m/s,得x=7940米
翻译：一列长120米的列车通过一个隧道.在10点时头部刚到达隧道,10点零4分时火车还有一半在隧道里.已知火车速度为120km/h,求隧道长度多少米?

1 隧道二极管-一种半导体二极管,是由L.伊萨吉基于隧道效应于1957年发现的.它是由重掺杂p_n半导体结组成,p_n 结会由于负偏压而短路,并且当加正向偏压时,在其适用范围它具有负电阻.其快的运行速度,致使它在许多电子领域成为一种有用的装置.在隧道二极管中,电流和电压特性波的形状,因为与从《价带〉到《导带〉隧道有关的大的隧道电流,会显著地受隧道效应的影响.由于在(p_n)结上的正向偏压的增加,隧道效应就变成越来越不显著.
2 隧道效应-一种效应,其中的电子能够通过窄势垒的隧道,如果这些电子被处理成典型的粒子,势垒会形成一禁区.那么,由于量子机制的缘故,从一个典型的容许区到另一区,电子隧道的有限概率就会提高.这个效应就被用来做隧道二极管.

隧道出了问题

As the train came to a sudden halt, like all other curious passengers, I opened the velvet green curtains of my train compartment in hopes to catch of glimpse of what was wrong. As I pulled the curtain, I had to adjust my eyes to the violent sunlight for a better view of what was going on. Before my eyes were used to such brightness, the train started moving again. Soon it passed a tunnel, and before I knew it, I arrived at Dover. Anywhere you turn you'd see a group of brightly dressed tourists busily engaged in their own little world clicking away with their cameras.
－－－－－－－－
这一段用了halt, adjust to, tunnel和 engaged in.写法比较像小说里面的一个段落.
中文翻译（中文翻译的不是很好,不过大概意思就是这样的）：
当火车突然停了下来（halt）的时候,我和所有其他好奇的乘客一样,把车厢内深绿色的窗帘拉开,试图着可以看到到底发生了什么事.当我刚把窗帘拉开,在眼睛还没有完全习惯那（adjust ... to）刺眼的阳光时,火车又开始开动了.很快的,火车经过了一个隧道（tunnel）,更在很快的就到达了多佛尔[英国的一个地名].不管你往那里看,都可以看到一群穿着鲜艳服饰的旅客们,沉醉在（engaged in...）他们自己的世界里,忙碌的按着相机快门.

1.time是不可数名词,用little修饰,这里是它的比较级less表"更少时间"
2."要再来一份三明治吗?"我们一般询问别人还要什么时通常用another(另一)而不用other(另一些),这里从sandwich也可以看出.
另:others可以看做是other things,类似的,
the other things→the others

across---throughside---sidesshall---shouldhave---be

句子为什么没主语呢?我认为这里的with 应该是伴随的,但是a plan for ,我有两种理解,一这里的a plan for 是一起的,一个什么什么计划,二是这里有省略的,plan作为先行词,后面省略which is,仅供参考

D
这道题考的是主谓一致.
前面的句子主语是人,你发现了吗?只有人才可以BUILD A TUNNEL,所以后面的句子的主语要和前面句子的主语一致,才行.所以只有D是人作主语.

tunnel
