完形填空题不同于单项选择填空题。单项填空题所给的是一个或两个句子，根据本句或前后句就可以判定所选的答案。而完形填空题所给的是一篇意思完整的短文，所选的答案处在整段或整篇文章之中。所以在做题前，必须先浏览全文，了解短文的大意，这是绝对不可以省略的一步。

The World’s Longest Bridge

Rumor has it that1 a legendary six—headed monster lurks in the deep waters of the Tyrrhenian Sea between Italy and the island of Sicily.____ (1)____ When completed in 2010，the world ’ s longest bridge will weigh nearly 300，000 tons—equivalent to the iceberg that sank the Titanic—and stretch 5 kilometers long.“That’s nearly 50 percent longer than any other bridge ever built，”says structural engineer Shane Rixon.

____(2) ____They’ re suspension bridges，massive structures built to span vast water channels or gorges.A suspension bridge needs just two towers to shoulder the structure’s mammoth weight，thanks to hefty supporting cables slung between the towers and anchored firmly in deep pools of cement at each end of the bridge.The Messina Strait Bridge will have two 54，100-ton towers，which will support most of the bridge’ s load.The beefy cables of the 1.2 meter in diameter, will hold up the longest and widest bridge deck ever built.

After lowering vertical“ suspender ”cables from the main rs will erect a 60 meter-wide 54.630-ton steel roadway, or deck——wide enough to accommodate 12 lanes of traffic.The deck’s weight will pull down on the cables with a force of 70，500 tons.In return，the cables yank up against their firmly rooted anchors with a force of 1 39。000 tons—equivalent to the weight of about 100，000 cars.Those anchors are essential.____(5)____

答案与题解：

1. C 选项C中有一个关键词beast，与第一句中的monster相呼应。所以，C是答案。

2. B 第二段第二句的主语是 They。由于表语是suspension bridges，They 替代的一定是前面句子出现过的bridges。六个选项中，只有B含有bridges。填在第二段段首，意思连贯。

3. E “空3”前面的句子中有 the first job 这几个词。有first，必有second/then。六个选项中，只有E含有The second job。所以，E是答案。

4.F “空4”前面的句子说的是，把这些吊索吊高定位是有难度的，不仅仅由于它们很长，还由于它们很重。F具体地介绍了它们的重量，应该是“空4”前面的句子的后续句。

5.D “空5”前面的句子说的是，桥桩很重要。为什么很重要呢?D解释了桥桩的作用，意思连贯，所以是答案。
