由1，2，3，4这四个数，组成个位数字不为2的没有重复数字的四位数，共有      个 答案：18　　The city of Venice, in Italy, is one of a kind. It is built on more than 120 islands, just off the coast. The islands are small and close together. The waterways between them are used as streets. They are called canals. 　　In this watery world, people use boats to get from place to place. Gondolas to place, small boats that are moved with one oar（桨）, were once the only boats used in the canals. But today motorboats make getting around faster; there are still lots of gondolas, though. Many visitors go to Venice all the year round. And they like to ride in the old-style（老式）boats. 　　If you aren't going far in this city, it's easier to go on foot. There are hundreds of narrow footpaths. About 100 low bridges connect the footpaths and islands. But these bridges cause problems for the boaters. When the sea tide（潮）is high, the canal water rises. People in the boats must duck to fit under bridges. (1)After reading the first paragraph, we can come to the conclusion that ________.
