Unit Two

Text A Classification Yard

A classification yard or marshalling yard is a railroad yard found at some freight train stations，used to separate railroad cars on to one of several tracks. First the cars are taken to a track，sometimes called a lead or a drill. From there the cars are sent through a series of switches called a ladder onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a hump to use the force of gravity to propel the cars through the ladder.

Freight trains which are made up of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train，which carries，for example，cars from the plant to a port，or coal from a mine to the

power plant. This shunting is done partly at the starting and final destinations and partly（for long-distance-hauling) in classification yards.

Hump Yards

These are the largest and most effective classification yards with the largest shunting capacity of several thousand cars a day. The heart of these yards is the hump：a track on a hill（hump) over which the cars are pushed by the engine after being uncoupled just before or at the top（hump crest) and then they roll，either as single cars or some coupled cars together, by gravity into their destination tracks in the classification bowl（the tracks where the cars are sorted）．

The speed of the cars rolling down from the hump into the classification bowl must be regulated because of the different natural speed of wagons（full or empty，heavy or light freight，number of axles) and the different filling of tracks（whether there are presently few or already many cars on it）．As concerns speed regulation there are two types of hump yards：without or with mechanisation by retarders. In the old non-retarder yards braking was generally done in Europe by railroaders who lay skates onto the tracks or in the USA by passengers on the cars. In the modern retarder yards this work is done by mechanized“rail brakes" called retarders.

高中英语 Unit 2 Poems单元小结教学案 新人教版选修6

Unit 2 Poems A Russian Poem Since childhood, Anton had often recited poems, accompanied on the piano and violin by pianists and violinists, at wedding ceremonies before brides and bridegroomsexchanged rings. Gradually, he found writing poems the most appropriate way to convey his joy and sorrow. When his poem Contradictory Blank won him a national championship and a scholarship to the Moscow University from a sponsor, he was just an unknown librarian. After getting his diploma, he devoted his life to writing poems. Using concrete but flexible language and the minimum of words is his style. He tried out different patterns and preferred nursery rhyme in particular. The following is a translation of one of his works made up of 3 sections： Little sparrow with heavy load， Ran out of energy and very cold； No compass and all sweat salty， Can you go through the endless darkness? Little balloon let out by the thread， Flew over c ottages and was very glad； With warmth transformed from sunlight， He said he could forever fly； Take it easy, little balloon； Don't tease the sparrow with his wound； On the bare branch and have a rest； This diamond heart will eventually get success. 俄国童谣 从童年时起，安东就常常在钢琴师或小提琴师的伴奏下在婚礼上朗诵诗歌，为新郎新娘交换戒指前的仪式助兴。渐渐地，他发现写诗是表达他的欢乐和悲伤的最合适方式。在他还是个不知名的图书管理员时，他的诗《矛盾的空白》就获得了全国诗歌创作冠军，并为他赢得一位赞助人提供的、到莫斯科大学深造的奖学金。获得文凭后，他将一生都投入到诗歌创作中。使用具体而灵活的语言和最少的词语数量是他的风格。他还喜欢尝试不同的诗歌形式，特别是童谣。下面有三部分组成的译文就是他的作品中的一首： 小麻雀，负重担，
