阅读下文，回答相关问题。
高山流水
①那天我们是去寻山的。
②我们顶着碧蓝的九月，披着金黄的九月，兴致勃勃地去寻山。那天的天气很高爽。我们的心灵跃动得很年轻，真是登峰的好日子——那座高峰，耸峙在梦境中，已经很久了。
③进入群山之中，坎坷曲折，就没有一条直路。山路虽然难走，我们心里明白，要攀登那座高峰，一定得耐心地走。何况山上到处有美妙的花草，蓊郁的林木，展开一片活鲜的绿！让我们的眉眼也绿了，心灵也绿了。
④生活在平地上的人，一旦爬上了高山，真不行。我们原是唱着歌来寻山的，不知什么时候，歌声已歇。山上美丽的景物，原先会引起我们一阵大叫的，不知什么时候，再没有精神去理睬。不错，山中有千般的好，可是，骄狂的人们哪，只能在马路上追遂，到山上来，就软弱得不如一只虫豸！
⑤盘盘旋旋，升升降降，路，不必说，愈往上爬就愈苦。时间，在山上。也失去了权威，日影已过午，看看那座峰尖，却似乎越来越远了。
⑥早晓得高峰是可望而不可及的，真不该来。
⑦山，并没请谁来！
⑧真的，山没有请谁来。山，威严地站在那儿，不假人以辞色，是我们自己要来寻山的。想登上绝顶，领受独立孤峰的喜悦，岂能不品尝寂寞趱路的况味？
⑨寂寞趱路，是我们真实的写照，我们是走在寂寞中了。有一半人落了队，剩下的人一句话都懒得讲。究竟是怎么回事？难道人的精神竟这么容易激扬而又容易消沉吗？想从记忆里找一句话鼓舞一下，看大家的脸色，我发现不是谈论哲学的时候！谈什么哲学？哲学在高山上完全没有用场。
⑩泉水的溅溅声，从静寂之中传来，这对我们是亲切的召唤。翻过一道山坡，就看一条细细的泉水，从那边陡峭的山坡上，蹦蹦跳跳地奔下来，在我们的脚下回旋成一道溪流，而后扩展开向下游流去。看到这一股清泉，谁能不喜悦呢？尤其是攀援在群山中正感国顿彷徨的时候，我们怎能不以近乎感激的心情欢呼起来？
⑪那一线银丝，从峰坳里流出，忽隐忽现，简直如同幻影一般地柔弱，真不知道它靠什么力量，能在山岳中开出一条河道来。可是，壁立的山崖挡不住它，嶙峋的怪石阻不了它，终于穿过一切的障碍，奔腾而去！谁能回答，泉水，究竟是柔弱还是刚强？
⑫我们是来寻山的，没登上峰顶却已经颓唐；我们没想寻觅泉水，泉水却给我们树立了一个榜样。
⑬我们不该学学这一脉山泉吗？
⑭不管人们怎么想，泉水只是自顾自地唱歌。如果你喜欢音乐，应该到山中来，听一听山泉之歌, 有时爽朗如银铃；有时激越如仰天吟啸；有时又轻轻地情人的私语。懂么？山泉之歌是自然的音乐啊！世间的音乐家，有谁能把这一份灵秀、晶莹、活力，谱进美妙的曲子？除了山泉，谁能？
⑮在这崇山峻岭间，山泉的歌唱给谁听呢？其实，我们不必顾虑山泉歌唱给谁听，我们如果不来听，也有别的来听。山爱听，谷爱听，一切大自然的家族都爱听，也许他们更能听得懂。我想，也许山泉根本就不要唱给谁听，不然它不会唱得那么悠然，唱给自己听，就不需什么理由。要说理由，也许活力无限的山泉就爱唱歌；或者说，爱唱歌的山泉才有活力吧！
⑯山泉是活力无限的生命之泉啊！在水深处，上层虽然平滑如镜，下层仍然流动不息。在浅滩上，飞溅起雪白的珠花，冲击岩石，漱荡幽壑，向山峦要道路。山泉，每一分钟，每一秒钟，都呈现着生生不已的流动。看遍种种的水，哪一种水能有山泉的生动？哪一种水又能有山泉的清澈？山泉，真像一片澄明而秀美的心灵啊！
⑰我们徘徊在泉水旁，不忍离开。
⑱我们不该学学这一脉的山泉吗？
⑲那天，我们终于登上了山峰。
⑳我们欣慰，不仅是因为到达封顶，更因为认识了高山和流泉——高山教我们以亘古的宁静，流泉教我们以永生的不息。
我们的生活中应该有歌，应该有高山流水之音的。
We are all learning English, but how can we learn English well? A student can know a lot about English, but maybe(可能) he can't speak English. If you want to know how to (如何) swim, you must get into the river. And if you want to be a football player, you must play football.
So, you see. You can learn English only by(通过) using(使用)it. You must listen to your teacher in class. You must read your lessons every day. You must speak English to your classmates and also you must write something sometimes. Then one day, you may find your English very good.
I'm taking my family to other countries to have a trip. My wife and I and our two children are all going along. My elder brother will go with us, too. He has never been overseas and he is even more excited than the children. My father is so old that he'd like to stay at home and take care of the house.
We're going by train to New York, and then take a ship to Europe. When we arrive in Europe, we're going to some countries for sightseeing (观光). We'll go to places either by train or by bus. We're going to fly home.
It took us a long time to decide where to go, but I think we’ll have a very interesting trip. We'll go to England, France and Italy. We also talked about how we would go to Europe. At first we wanted to fly because it would be faster and would save more time, But my brother likes to take a boat trip and the children like that, too.
