【正文】 d a 2500 horsepower engine. Although Campbell reached a speed of over 304 miles per hour, he had great difficulty in controlling the car because a tyre burst during the first run. After his attempt, Campbell was disappointed to learn that his average speed had been 299 miles per hour. However, a few days later, he was told that a mistake had been made. His average speed had been 301 miles per hour. Since that time, racing drivers have reached speeds of over 400 miles an hour. FollowingWhen you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the . If the Houses of Parliament had hot been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the . you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down ! During a bullfight, a drunk suddenly wandered into the middle of the ring. The crowd began to shout, but the drunk was unaware of the danger. The bull was busy with the matador at the time, but it suddenly caught sight of the drunk who was shouting rude remarks and waving a red cap. Apparently sensitive to criticism, the bull forgot all about the matador and charged at the drunk. The crowd suddenly grew quiet. The drunk, however, seemed quite sure of himself. When the bull got close to him, he clumsily stepped aside to let it pass. The crowd broke into cheers and the drunk bowed. By this time, however, three men had e into the ring and they quickly dragged the drunk to safety. Even the bull seemed to feel sorry for him, for it looked on sympathetically until the drunk was out of the way before once more turning its attention to the matador.Mr Eames,39。lesson69 But not murder! 并非謀殺！waiting room !39。ll e with you,39。m going to the dentist.39。 he asked, before I had finished speaking.m going to.. .39。39。 Bert answered. 39。Fancy meeting you here !39。I crossed the street to avoid meeting him, but he saw me and came running towards me. It was no use pretending that I had not seen him, so I waved to him. I never enjoy meeting Bert Dykes. He never has anything to do. No matter how busy you are, he always insists on ing with you.

Winter was ing on and the hills threatened the surrounding villages with destruction, for heavy rain would not only wash away the soil but would cause serious floods as well. When the fire had at last been put out, the forest authorities ordered several tons of a special type of grassseed which would grow quickly. The seed was sprayed over the ground in huge quantities by aeroplanes. The planes had been planting seed for nearly a month when it began to rain. By then, however, in many places the grass had already taken root. In place of the great trees which had been growing there for centuries, patches of green had begun to appear in the blackened soil. Geoffrey Hampden has a large circle of friends and is very popular at parties. Everybody admires him for his fine sense of humoreverybody, that is, except his sixyearold daughter, Jenny.

After having been instructed to drive out of town, I began to acquire confidence. Sure that I had passed, I was almost beginning to enjoy my test.

The only passengers, a young woman and her two baby daughters, were unhurt. It was the middle of winter. Snow（5）現(xiàn)場踏勘情況研究范圍本報(bào)告對市場需求、產(chǎn)品方案、生產(chǎn)規(guī)模、工藝技術(shù)方案、原輔助材料及燃料供應(yīng)，建廠條件和廠址、公用工程和輔助設(shè)施方案，環(huán)境保護(hù)和勞動安全，公司組織、勞動定員，項(xiàng)目實(shí)施規(guī)劃、投資估算和資金籌措及財(cái)務(wù)評價(jià)等問題進(jìn)行研究。中國地質(zhì)大學(xué)為本公司提供強(qiáng)有力技術(shù)支撐，生產(chǎn)工藝自動化程度高、規(guī)范科學(xué)、軟技術(shù)是國家發(fā)明專利，引進(jìn)先進(jìn)的德國濕法超細(xì)設(shè)備。本項(xiàng)目的實(shí)施和利于聯(lián)合初級加工廠，起到龍頭帶動作用，真正形成一個(gè)大產(chǎn)業(yè)，一個(gè)集團(tuán)，全面整合優(yōu)勢資源，最大限度的提高產(chǎn)品附加值。同時(shí)項(xiàng)目可安排200余人就業(yè)。從協(xié)會調(diào)查分析的150多家生產(chǎn)企業(yè)采看，年生產(chǎn)規(guī)模5萬噸以上的占4％左右，年生產(chǎn)規(guī)模2萬—5萬噸的占10％，年生產(chǎn)規(guī)模1萬—2萬噸的占26％，其他60％左右的企業(yè)生產(chǎn)規(guī)模小于1萬噸。與此同時(shí)，我國對納米級碳酸鈣的科研及其工業(yè)應(yīng)用的研究，受到了高度的重視，并加快了工業(yè)化步伐。未來的幾年和十幾年里，我國塑料加工工業(yè)對碳酸鈣產(chǎn)品的需求有增無減，占國內(nèi)消費(fèi)結(jié)構(gòu)總量的40％，為碳酸鈣工業(yè)的發(fā)展提供了良好的機(jī)遇和光明的市場前景。2005年造紙礦物顏料總消費(fèi)量可能達(dá)到350萬噸，其中碳酸鈣約170萬噸．造紙業(yè)也將成為碳酸鈣最大的應(yīng)用市場。初級產(chǎn)品用于生產(chǎn)室內(nèi)和室外淺色涂料噴涂料壁，精加工產(chǎn)品用于高亮度噴涂。我國年耗膠量達(dá)235萬噸，僅次于美國，居世界第二位。目前在橡膠制品領(lǐng)域，重質(zhì)碳酸鈣的應(yīng)用比重要小于輕質(zhì)碳酸鈣，而且增長速度將要小于造紙和塑料領(lǐng)域，但超細(xì)活性重質(zhì)碳酸鈣在橡膠制品中的比重將不斷提高，2002年碳酸鈣在橡膠填料中消費(fèi)為9萬噸，預(yù)測2006年為5萬噸，2010年為12萬噸，％。另外，碳酸鈣在油墨，醫(yī)藥，保健食品、飼料等領(lǐng)域也有一些應(yīng)用。目前，碳酸鈣廣泛應(yīng)用于造紙，塑料、塑料薄膜、化纖、橡膠、膠粘劑、密封劑、日用化工、化妝品，油漆，油墨、涂料、醫(yī)藥、食品(如口香糖，巧克力等)等行業(yè)。填充母料以重鈣粉為主要原料(重鈣粉占80％左右)，通過偶聯(lián)劑、載體樹脂、高壓聚乙烯、助劑等化工原料加熱混合生產(chǎn)而成，具有分散性好，與樹脂結(jié)合力強(qiáng)。近20年來，市場需求不斷擴(kuò)大，已成為全球造紙工業(yè)和塑料工業(yè)用量最大的工業(yè)礦物原料之一。但是，我國重鈣與輕鈣在塑料中的消費(fèi)比重遠(yuǎn)未達(dá)到歐美等發(fā)達(dá)國家的水平。因此，超細(xì)和表面改性后的重質(zhì)碳酸鈣在塑料制品中的應(yīng)用范圍和用量還將擴(kuò)大，市場發(fā)
