　　金风换成了北风，秋去冬来了。冬天刚刚冒了个头，落了-场初雪，我满庭斗艳争娇的芳菲，顿然失色，鲜红的老来娇，还有各色的傲霜菊花，一夜全白了头。两棵丁香，叶子簌簌辞柯了，像一声声年华消失的感叹。

　　每到这个季节，十一月上旬，我生上了炉火，一直到明年四月初，将近半年的时光，我进入静多动少的生活。每到安炉子和撤火的时候，我的心里总有些感触，季候的变迁，情绪的转换，打下了很鲜明、很深刻的印记。

　　我的小四合院，每到冬季，至少要安六个炉子，日夜为它奔忙，我的家人总是念咕说：安上暖气多省事呵，又干净。我也总是用我的一套理由做挡箭牌：安暖气花费太大呀，开地道安管子多麻烦呵，几吨煤将放在何处？还得有人夜里起来烧锅炉……，我每年这样搪塞，一直搪塞了二十一年。其实，别的是假的，我中心的一条是：我爱炉火！

　　我住北房，三明两暗。左右两间有两个炉子，而当中的会客室，却冷冷清清，娇花多盆，加上两套沙发，余地供回旋的就甚少了。客人来了，大衣也不脱，衣架子成空摆设。到我家做客的朋友们，都说我屋子里的温度太低了。会客室里确是有点清冷，而我的写作间兼寝室却暖和和的。炉子，成为我亲密的朋友，几十年来，它的脾气我是摸透了。它，有时暴烈，有时温柔，它伴我寂寞，给我安慰和喜悦。窗外，北风呼号，雪花乱飘，这时，炉火正红，壶水正沸，恰巧一位风雪故人来，一进门，打打身上的雪花，进入了我的内室，沏上一杯龙井，泡沫喷香，相对倾谈，海阔天空。水壶咝咝作响，也好似参加了我们的叙谈，人间赏心乐事，有胜过如此的吗？

　　每晚，我必卧在床上，对着孤灯，夜读至十时，或更迟些。炉火伴我，它以它的体温温暖我，读到会心之处，忽然炉子里砰砰爆了几声，像是为我欢呼。有时失眠了，辗转不能安枕，瞥看炉子里的红光一点，像只炯炯的明眸，我心安了，悠悠然，入了朦胧的境界。

　　暖气，当然温暖，也干净，但是呵，它不能给我以光，它缺少性格与一种活力。我要光。我要性格。我要活力。

　　我想到七八岁上私塾的时候，冬天，带上个铜“火箱”，里边放上几块烧得通红的条炭，用灰把它半掩住，“火箱”盖上全是蜂窝似的小孔，手摸上暖乎乎的，微微的火光从小孔里透露出来，给人以光辉，它不仅使人触感上感到温暖，而且透过视觉在心灵上感受到一种启示与希望的闪光。

　　有这种生活经验的人，会饶有情味地回忆到隆冬深夜，置身在旷山大野中，几个同伴围在篝火旁边取暖的动人的情景。火，以它的巨大热力使人通体舒畅，它的火柱冲天而起，在黑暗中给人一种巨大的鼓舞力量与向前冲击的勇气。在它的猛烈的燃烧中，进出噼噼啪啪的爆炸，不像一声声鼓点吗？

　　炉火当然不是铜“火箱”，也不是篝火，可是它们也有相同的性格：它们发热，它们发光，它们也能发出震撼心灵的声响。几十年来我独持异议不安暖气，始终留恋着炉火，原因就在此。1984年11月24日

水下旅馆

In a bay near Almeria in Southern Spain will be built the world’s first underwater residence for tourists. The hotel will be 40 feet down in the Mediterranean. As all the world opened to tour operators, there was still a frontier behind which lay three quarters of the globe’s surface, the sea; in whose cool depths light fades; no winds blow; there are no stars. There even the most bored travelers could recapture their sense of romance, terror or beauty. For a submerged hotel is such a beautiful idea．

The hotel will cost 170,000 and will be able to accommodate up to ten people a night. Up until now only scientists and professional divers have lived under the sea, but soon, for the first time, the public will be able to go down into the darkness. They will have to swim down in diving suits, but at 40 feet there would be no problem about decompression.

Design of the hotel was crucial. Most of the underwater structures used before had been in the shape of a diving bell or submarine. Professional divers could cope with such things but ordinary people would run the risk of violent claustrophobiA．Then an Austrian architect had the idea of making three interconnecting circular structures, 18 feet in diameter, and looking much like flying saucers. They would be cast in concrete and launched from the shore. Towed into position they would then be sunk. A foundation of cast concrete would already be in place on the sea beD．Pylons would attach the structures to this. Once in position the structures would be pumped dry. The pylons, made to withstand an uplift pressure of 350 tons, would then take the strain.

Cables linking the underwater structures to the hotel on shore would connect it with electricity, fresh water, television, and an air pump, and also dispose of sewage. Entry would be from underneath, up a ladder; because of the pressure inside there would be no need of airlocks or doors.

The first structure would include a changing room and a shower area, where the divers would get out of their gear. There would also be a kitchen and a lavatory. The second structure would contain a dining room/lecture theater, and sleeping accommodation for eight people. The third structure would contain two suites. A steward would come down with the ten customers, to cook and look after them. Television monitors would relay all that went on to the shore so that discussions on the sea bed could be transmitted to all the world．

Around the hotel there are plans to build a strange secret garden, over 100 yards square, of plastic shapes, curves, circles, hollows. This would have a dual function. First, to attract fish who would see it as a shelter and hiding place; secondly, to allow guests looking out of the reinforced windows to see a teeming underwater life.

So far at the site a diving tower 33 feet deep has been installed for diving instruction. An aquarium has been built, and zoologists from Vienna University are in regular attendance to supervise its stocking. There are storage cupboards full of the plastic shapes for the underwater garden and there is a model of the hotel. All that is needed now is permission from the Spanish Government to start building.

The purpose of television monitors under the sea would be to relay（）

A．instructions from the sea bed to the shore

B．news from the shore to the sea bed

C．information from the world to the sea bed

D．information to the world from the sea bed
