Lesson 17 The longest suspension bridge(a little too long?) in the Lesson 17 The longest suspension bridge in the world(good) 世界上最長的
Listen to the tape then answer the question below.
How is the bridge(over exaggerated?) supported?
Verrazano, an Italian about whom little is known, sailed(mind the vowel) into New York Harbour in 1524 and named it Angouleme. He described it as 'a very agreeable situation(good) located within two small hills in the midst of which flowed a great river.' Though Verrazano is by no means considered to be a great explorer, his name will probably remain immortal, for on November 21st, 1964, the longest suspension bridge in the world(mind the l sound) was named after him.
The Verrazano Bridge, which was designed by Othmar Ammann, joins Brooklyn to Staten Island. It has a span of 4,260 feet. The bridge is so long that the shape of the earth had to be taken into account by its designer. Two great towers support four huge(good) cables. The towers(sounds like towel) are built on immense underwater platforms made of steel(good) and concrete. The platforms extend to a depth of over 100 feet under the sea. These alone took sixteen months to build. Above(good!) the surface of the water, the towers(sounds like towel) rise to a height of nearly 700 feet. They support the cables from which the bridge has been suspended. Each of the four cables contains 26,108 lengths of wire. It has been estimated that if the bridge(sounds good) were packed with cars, it would still only be carrying a third of its total capacity. However, size and strength are not the only important things about this bridge. Despite its immensity, it is both simple and elegant, fulfilling its designer's dream to create 'an enormous object drawn as faintly as possible'.
急著出門,找得不夠仔細,說錯的地方也不能負責,僅供你參考。
至於那個“辦法”,沒啥捷徑。這兩天在想那個“石頭湯”現象,興許是個法子。
有時間再聊。
