“across、cross、through、over、via、by”的区别across,cross是横过的意思across是介词,通常在用go,run,swim.等搭配cross是动词,通常可以直接放在句子中through是穿过跟across一样介词,通常在用go,run,swim.等搭配through与across的不同在于方向through是直过across是横过例:I went across the road = I cross the road我横过马路(经斑马线)The car went through the road汽车经过马路(沿着马路)over 是越过,用法与across,through相同,都是介词,通常在用go,run,swim.等搭配through有3种词性“介词”，“副词”和“形容词”；而via只有一种词性“介词”。

我想既然这2个词要区别对待的时候，一定都是它们都被用做“介词”的时候。

下面来比较一下：through做介词的时候，有如下意思：（1）穿越：从一边进，从相对的或另一边出：例如： went through the tunnel.穿过隧道（2）在…之中或之间；在…之中：例如：a walk through the flowers.在花丛中散步（3）由，经过：例如：climbed in through the window.从窗户爬进去（4）通过：用…途径或媒介：例如：bought the antique vase through a dealer.通过一个商人买到这只古花瓶via做为介词只有2种意思：（1）经过：例如：went to Pittsburgh via Philadelphia.经过费城到匹兹堡（2）通过，凭借：例如：sent the letter via airmail.通过空邮寄信总结起来。

用via的地方都可以用through。

因为via的2个意思都被through包括了。

小学英语常用介词用法第一篇：小学英语常用介词用法小学英语常用介词用法摘要：英语介词并不很多，但其用法灵活多样。

掌握常用介词的用法及常见的介词搭配，是学习英语的重点和难点。

关键词：英语介词用法介词是英语中一个十分活跃的词类，在句子的构成中起着非常重要的作用。

介词也是英语中的一个最少规则可循的词类，几乎每一个介词都可用来表达多种不同的含义；不同的介词往往又有十分相似的用法。

因此，要学好介词，最好的方法就是在掌握常用介词的基本用法的基础上，通过广泛阅读去细心地揣摩，认真地比较，归纳不同的介词的用法，方能收到良好的效果。

那么，什么是介词呢？小学常用的介词都有哪些以及它们的用法？一·介词 1 介词的含义介词又叫前置词，是一种虚词，用来表明名词，代词（或相当于名词的其他词类，短语或从句）与句中其他词关系的词。

介词不能重读，不能单独做句子成分，必须与它后面的名词或代词（或相当于名词的其他词类，短语或从句）构成介词短语，才能在句子中充当一个成分。

介词后面的名词，代词或相当于名词的部分称为介词宾语，简称介宾。

2介词的分类1）根据介词的构成形式，可将介词分为简单介词，合成介词，双重介词，短语介词四类。

而小学英语中涉及到的介词仅为简单介词和一些短语介词，如：after（在……之后），against（反对），along （沿着），among（在……之中），at（在），behind（在……后面），near（在……附近），into（在……里），in（在……内，用，戴），from（从），for（为，给），except（除……之外），by（乘，在，由，到），on the left(在左边),on the right(在右边)······2）根据介词的意义，可将介词分为表示空间关系的介词，表示时间的介词，表示原因，目的的介词，表示手段的介词和其他介词。

如：表示时间的介词in，on，at，表示方位的介词in，on，to······下文则主要是从介词的意义方面来讲介词的用法。

Through the TunnelGoing to the shore on the first morning of the holiday, the young English boy stopped at a turning of the path and looked down at a wild and rocky bay, and then over to the crowded beach he knew so well from other years. His mother walked on in front of him, carrying a bright-striped bag in one hand. Her other arm, swinging loose, was very white in the sun. The boy watched that white, naked arm, and turned his eyes, which had a frown behind them, towards the bay and back again to his mother. When she felt he was not with her, she swung round. "Oh, there you are, Jerry.”She said. She looked impatient, and then smiled. "Why, darling, would you rather not come with me? Would you rather..." She frowned, conscientiously worrying over what amusements he might secretly be longing for which she had been too busy or too careless to imagine. He was very familiar with that anxious, apologetic smile. Contrition sent him running after her. And yet, as he ran, he looked back over his shoulder at the wild bay, and all morning, as he played on the safe beach, he was thinking of it.Next morning, when it was time for the routine of swimming and sunbathing, his mother said, "Are you tired of the usual beach, Jerry? Would you like to go somewhere else?""Oh, no!" he said quickly, smiling at her out of that unfailing impulse of contrition a sort of chivalry. Yet, walking down the path with her, he blurted out , "I'd like to go and have a look at those rocks down there."She gave the idea her attention. It was a wild-looking place, and there was no one there, but she said, "Of course, Jerry. When you've had enough, come to the big beach. Or just go straight back to the villa, if you like." She walked away, that bare arm, now slightly reddened from yesterday's sun, swinging. And he almost ran after her again, feeling it unbearable that she should go by herself, but he did not.She was thinking: Of course he's old enough to be safe without me. Have I been keeping him too close? He mustn't feel he ought to be with me. I must be careful.He was an only child, eleven years old. She was a widow. She was determined to be neither possessive nor lacking in devotion. She went worrying off to her beach.As for Jerry, once he saw that his mother had gained her beach, he began the steep descent to the bay . From where he was, high up among red-brown rocks, it was a scoop of moving bluish green fringed with white. As he went lower, he saw that it spread among small promontories and inlets of rough, sharp rock, and the crisping, lapping surface showed stains of purple and darker blue. Finally, as he ran sliding and scraping down the last few yards, he saw an edge of white surf, and the shallow, luminous movement of water over white sand, and, beyond that, a solid, heavy blue.He ran straight into the water and began swimming. He was a good swimmer. He went out fast over the gleaming sand, over a middle region where rocks lay like discolored monsters under the surface, and then he was in the real sea a warm sea where irregular cold currents from the deep water shocked his limbs.When he was so far out that he could look back not only on the little bay but past the promontory that was between it and the big beach, he floated on the buoyant surface and looked for his mother. There she was a speck of yellow under an umbrella that looked like a slice of orange-peel. He swam back to shore, relieved at being sure she was there, but all atonce very lonely.On the edge of a small cape that marked the side of the bay away from the promontory was a loose scatter of rocks. Above them, some boys were stripping off their clothes. They came running, naked, down to the rocks. The English boy swam towards them, and kept his distance at a stone's throw. They were of that coast, all of them burned smooth dark brown, and speaking a language he did not understand. To be with them, of them, was a craving that filled his whole body. He swam a little closer; they turned and watched him with narrowed, alert dark eyes. Then one smiled and waved. It was enough. In a minute he had swum in and was on the rocks beside them, smiling with a desperate, nervous supplication. They shouted cheerful greetings at him, and then, as he preserved his nervous, uncomprehending smile , they understood that he was a foreigner strayed from his own beach, and they proceeded to forget him . But he was happy. He was with them.They began diving again and again from a high point into a well of blue sea between rough, pointed rocks. After they had dived and come up, they swam round, hauled themselves up , and waited their turn to dive again. They were big boys men to Jerry. He dived, and they watched him, and when he swam round to take his place, they made way for him. He felt he was accepted, and he dived again, carefully, proud of himself.Jerry dived, shot past the school of underwater swimmers , saw a black wall of rock looming at him , touched it, and bobbed up at once to the surface, where the wall was a low barrier he could see across. There was no one visible; under him, in the water, the dim shapes of the swimmers had disappeared. Then one and then another of the boys came up on the far side of the barrier of rock, and he understood that they had swum through some gap or hole in it. He plunged down again. He could see nothing through the stinging salt water but the blank rock. When he came up, the boys were all on the diving rock, preparing to attempt the feat again. And now, in a panic of failure, he yelled up, in English, "Look at me ! Look!" and he began splashing and kicking in the water like a foolish dog.They looked down gravely, frowning. He knew the frown. At moments of failure, when he clowned to claim his mother's attention, it was with just this grave, embarrassed inspection that she rewarded him. Through his hot shame, feeling the pleading grin on his face like a scar that he could never remove, he looked up at the group of big brown boys on the rock and shouted "Bonjour! Merci! Au revoir! Monsieur, monsieur!" while he hooked his fingers round his ears and waggled them.Water surged into his mouth; he choked, sank, came up. The rock, lately weighted with boys, seemed to rear up out of the water as their weight was removed. They were flying down past him, now, into the water; the air was full of falling bodies. Then the rock was empty in the hot sunlight. He counted one, two, three...At fifty he was terrified. They must all be drowning beneath him, in the watery caves of the rock! At a hundred he stared around him at the empty hillside, wondering if he should yell for help. He counted faster, faster, to hurry them up, to bring them to the surface quickly, to drown them quickly anything rather than the terror of counting on and on into the blue emptiness of the morning. And then, at a hundred and sixty, the water beyond the rock was full of boys blowing like brown whales. They swam back to the shore without a look at him.He climbed back to the diving rock and sat down, feeling the hot roughness of it under his thighs. The boys were gathering up their bits of clothing and running off along the shore toanother promontory. They were leaving to get away from him. He cried openly, fists in his eyes . There was no one to see him, and he cried himself out.It seemed to him that a long time had passed, and he swam out to where he could see his mother. Yes, she was still there, a yellow spot under an orange umbrella. He swam back to the big rock, climbed up, and dived into the blue pool among the fanged and angry boulders . Down he went, until he touched the wall of rock again. But the salt was so painful in his eyes that he could not see.He came to the surface, swam to shore, and went back to the villa to wait for his mother. Soon she walked slowly up the path, swinging her striped bag, the flushed, naked arm dangling beside her. "I want some swimming goggles, " he panted, defiant and beseeching.She gave him a patient, inquisitive look as she said casually, "Well of course, darling."But now, now, now! He must have them this minute, and no other time. He nagged and pestered until she went with him to a shop. As soon as she had bought the goggles, he grabbed them from her hand as if she were going to claim them for herself , and was off, running down the steep path to the bay.Jerry swam out to the big barrier rock, adjusted the goggles, and dived. The impact of the water broke the rubber-enclosed vacuum, and the goggles came loose. He understood that he must swim down to the base of the rock from the surface of the water. He fixed the goggles tight and firm, filled his lungs, and floated, face down, on the water. Now he could see. It was as if he had eyes of a different kind fish-eyes that showed everything clear and delicate and wavering in the bright water.Under him, six or seven feet down, was a floor of perfectly clean, shining white sand, rippled firm and hard by the tides. Two greyish shapes steered there, like long, rounded pieces of wood or slate. They were fish. He saw them nose towards each other, poise motionless, make a dart forward, swerve off, and come round again. It was like a water dance. A few inches above them, the water sparkled as if sequins were dropping through it. Fish again myriads of minute fish, the length of his finger-nail, were drifting through the water, and in a moment he could feel the innumerable tiny touches of them against his limbs. It was like swimming in flaked silver. The great rock the big boys had swum through rose sheer out of the white sand, black, tufted lightly with greenish weed. He could see no gap in it. He swam down to its base. Again and again he rose, took a big chestful of air, and went down. Again and again he groped over the surface of the rock, feeling it, almost hugging it in the desperate need to find the entrance. And then, once, while he was clinging to the black wall, his knees came up and he shot his feet out forward and they met no obstacle. He had found the hole.He gained the surface, clambered about the stones that littered the barrier rock until he found a big one , and, with this in his arms, let himself down over the side of the rock. He dropped, with the weight, straight to the sandy floor. Clinging tight to the anchor of stone, he lay on his side and looked in under the dark shelf at the place where his feet had gone. He could see the hole. It was an irregular, dark gap, but he could not see deep into it. He let go of his anchor, clung with his hands to the edges of the hole, and tried to push himself in.He got his head in, found his shoulders jammed, moved them in sidewise, and was inside as far as his waist. He could see nothing ahead. Something soft and clammy touched his mouth, he saw a dark frond moving against the greyish rock, and panic filled him. He thought of octopuses, of clinging weed. He pushed himself out backward and caught a glimpse, as heretreated, of a harmless tentacle of seaweed drifting in the mouth of the tunnel. But it was enough. He reached the sunlight, swam to shore, and lay on the diving rock. He looked down in the blue well of water. He knew he must find his way through that cave, or hole, or tunnel, and out the other side.First, he thought, he must learn to control his breathing. He let himself down into the water with another big stone in his arms, so that he could lie effortlessly on the bottom of the sea. He counted. One, two, three. He counted steadily. He could hear the movement of blood in his chest. Fifty-one, fifty-two...His chest was hurting. He let go of the rock and went up into the air. He saw that the sun was low. He rushed to the villa and found his mother at her supper. She said only "Did you enjoy yourself?" and he said "Yes".All night the boy dreamed of the water-filled cave in the rock, and as soon as breakfast was over he went to the bay.That night his nose bled badly. For hours he had been underwater, learning to hold his breath, and now he felt weak and dizzy. His mother said, "I shouldn't overdo things, darling, if I were you. "That day and the next, Jerry exercised his lungs as if everything, the whole of his life, all that he would become, depended upon it . And again his nose bled at night, and his mother insisted on his coming with her the next day. It was a torment to him to waste a day of his careful self-training, but he stayed with her on that other beach, which now seemed a place for small children, a place where his mother might lie safe in the sun. It was not his beach.He did not ask for permission, on the following day, to go to his beach. He went, before his mother could consider the complicated rights and wrongs of the matter. A day's rest, he discovered, had improved his count by ten. The big boys had made the passage while he counted a hundred and sixty. He had been counting fast, in his fright . Probably now, if he tried, he could get through that long tunnel, but he was not going to try yet. A curious, most unchildlike persistence, a controlled impatience, made him wait. In the meantime, he lay underwater on the white sand, littered now by stones he had brought down from the upper air, and studied the entrance to the tunnel. He knew every jut and corner of it, as far as it was possible to see. It was as if he already felt its sharpness about his shoulders【考点解析】1. 辨析unfailing (para.3)和lastingunfailing:(尤指优良的特性)无尽的；无穷的；永久的e.g.①with unfailing inter est 永不衰竭的兴趣；②an unfailing admirer of modern art 永远热爱现代艺术的人。

穿越海底隧道的英语作文Crossing the Undersea Tunnel。

The undersea tunnel is one of the most amazing engineering feats in the world. It is a tunnel that runs beneath the sea, connecting two land masses that are separated by water. The tunnel is usually made of concreteor steel, and it is designed to withstand the pressure of the water above it.I had always been fascinated by the idea of crossingthe undersea tunnel, so when I had the opportunity to do so, I jumped at the chance. I was on a trip to Europe, and oneof the things on my bucket list was to cross the undersea tunnel that connects England and France. The tunnel iscalled the Channel Tunnel, or the Chunnel for short.The Chunnel is 31 miles long, and it took us about 35 minutes to cross it. We boarded the Eurostar train in London, and it took us through the tunnel to Calais, France.The train travels at a speed of about 100 miles per hour, and it was a smooth ride.As we entered the tunnel, I couldn't help but feel a little nervous. I was crossing the English Channel, one of the busiest shipping lanes in the world, and I was doing it underground. But as we traveled deeper into the tunnel, my nerves began to calm. The tunnel is well-lit, and there are emergency exits every few hundred meters.The Chunnel is an engineering marvel. It was built in the 1990s, and it took over five years to complete. The tunnel was dug using a giant boring machine, and it was lined with concrete and steel. The tunnel is divided into three sections: two rail tunnels and a service tunnel. The rail tunnels are used by trains, while the service tunnelis used for maintenance and emergencies.As we emerged from the tunnel on the French side, Ifelt a sense of accomplishment. I had crossed the undersea tunnel, something that only a few people in the world have done. The Chunnel is a testament to human ingenuity andengineering, and it is a symbol of the close ties between England and France.In conclusion, crossing the undersea tunnel was an unforgettable experience. The Chunnel is an amazing engineering feat, and I feel lucky to have had the opportunity to cross it. If you ever have the chance to cross the undersea tunnel, I highly recommend it. It is an experience that you will never forget.。
